Scientific News Boron Nitride Graphene Mixture May Be Suitable For Next-Generation Green Cars

Scientific community has long been fascinated by boron nitride due to its unique properties: sturdy, ultra-thin transparent, insulating and lightweight. The boron is a material that can be used by a wide range of researchers.
According to researchers at Rice University a graphene film separated by boron nanotube columns could be used as a material for storing fuel hydrogen in automobiles.

The Department of Energy is setting the benchmark in storage materials to make hydrogen fuel a viable option for light vehicles. A new computational study by materials scientist Rouzbeh Sharsavari of Rice Lab has determined that pillared Boron Nitride and graphene may be suitable candidates.

Shahsavari's lab determined the elastic and columnar graphene structures by computer simulation, and then processed the boron nanotubes to create a mixture that simulates an unique three-dimensional structural design. (A sample consisting of boron nanotubes that are seamlessly bonded with graphene is prepared.

As the pillars of the building provide space between floors for people, so do the pillars within the graphene made from boron-nitride. The goal is to keep them inside and get out as necessary.

The researchers discovered that the latest simulations of molecular dynamics showed that pillared-graphene and pillared-boron nitride-graphene have a high surface area (about 2.547 square meters/square meter) as well as good recyclability in ambient conditions. The researchers' model suggests that adding lithium and oxygen to the materials will improve their ability to combine with hydrogen.

They concentrated their simulations on four different variants: either a graphene pillared with boron or lithium, or a graphene pillared with boron or lithium.

The best graphene at room temperature was oxygen-doped boron oxide graphene. This graphene weighs 11.6% (weight capacity) and 60 g/L volume capacity.

The material's hydrogen weight was 14.77% in cold weather at -321 Fahrenheit.

The current US Department of Energy economic storage media goal is to store more hydrogen than 5.5% in weight and 40 grams of hydrogen per liter under moderate conditions. The ultimate target is 7.5% weight and 70 gram per liter.

Shahsavari explained that the hydrogen atoms adsorb on boron-nitride graphene without oxygen doping due to a weak van der Waals force. When the material has been doped with oxygen the atoms firmly bind to the mix and create a surface that is better for hydrogen. According to Shahsavari, this can be done under pressure, and the hydrogen may then be withdrawn after the pressure is released.

"Oxygen and hydrogen are known to have a strong chemical affinity." "Oxygen, and hydrogen have been known to share a strong chemical affinity."

Shahsavari explained that the boron nitride polarization properties combined with the graphene electron mobility make the material highly adaptable in application.

Shahsavari explains that "we are looking for the best point" which describes ideal conditions such as the balance of surface area, weight and material as well as the operating temperature and pressure. This is only possible through computational modeling. We can test many different changes very quickly. In just a couple of days, the experimenter is able to finish the work that would normally take months.

He said these structures are strong enough to easily surpass the requirements of Department of Energy. The hydrogen fuel tank, for example, can withstand up to 1,500 charging and discharge cycles.

Compound Name TiH2 Powder Titanium Hydride Application For Welding And Catalysts

The titanium hydride used in powder metallurgy and metal-ceramic sealing is also used to provide titanium for the alloy powder.

Titanium Hydride is very fragile and can be used for powdered titanium. The hydride is also used to weld. Thermal decomposition of titanium hydride precipitates new, ecological hydrogen and Titanium metal. This increases the strength and promotes welding.

PNNL's collaborators and PNNL discovered a method to get around this issue six years ago. They additionally developed a low cost way of supplying material at a commercial scale. Instead of starting with molten Titanium, the team substituted titanium-hydride (TiH2) Powder.

In the last few years, a BE PM-Ti alternative approach has been developed that allows for the production of BE components which are almost poreless at one time. This method uses vacuum sintering titanium hydride (TiH2) instead of Ti-steel powder. TiH2 powders will dehydrogenate during the entire sintering process at mild temperatures, before being sintered under vacuum at high temperature.

Current implant requirements include biocompatibility and bone-like mechanical properties. Porous Titanium can meet these needs if enough porosity is obtained, as well as large pores and interconnections that allow bone to grow. Porous components are created from TiH2 based feedstocks with space holders.

Newly 3000°C Ablative Ceramic Coating Successfully Developed - Multi-boron-containing Single-phase Carbide

Boron carbide is also known as black Diamond. It has a molecular structure of B4C. The powder is typically grayish. It is one the three hardest materials known (the other two being diamond and cubic boronnitride). It can be found in many industrial applications, including tank armor and body armor. It has a Mohs toughness of 9.3. A large number of tests were conducted by the team of Academician Huang Boyun of Central South University’s National Laboratory of Powder Metallurgy to develop a new ceramic coating and composite materials that are resistant to 3000°C ablation. This discovery may pave a way for hypersonic vehicle development.

According to Professor Xiong Xiang of the Institute of Powder Metallurgy of Central South University's Institute of Powder Metallurgy (IPM), hypersonic flight is defined as a flight speed that is at least 6120 km/h, or 5 times faster than the speed of the sound. With such high speeds, a flight from Beijing to New York could be completed in just 2 hours if key structural components can withstand air friction and hot-air impact up to 2000-3000 °C without damage. . Central South University has developed ceramic composites and coatings for ultra-high temperatures that provide better protection of the above components. The world's very first synthesis of a quaternary boron containing carbide, single-phase ultra high temperature ceramic material has been reported. It is made into a coating and "fuses" perfectly with carbon-carbon. In the field of developing new materials, mixed materials are studied in binary compound system. The successful application of materials based on quaternary system will be greatly promoted by its development.

The new ceramic coated carbon/carbon material is composed by a single-phase carbide with a stable carbide structural structure. It contains zirconium elements, titanium, carbon, and boron. Infiltration of a multiceramic phase is the main method for obtaining it. The ultra high temperature ceramic combines high temperature adaptability carbides and anti-oxidation borides. This makes the coatings, composites, and materials exhibit superior ablation and thermal shock resistance. The ceramic oxide can withstand an ultra-high temperature of 3000 degC and has low oxygen diffusion rates, self-healing properties at high temperatures, dense ceramic coatings, and gradient structures. It also exhibits a lower material content than other ceramic systems. Ablation loss rate.

The above composites and coatings are superior in ablation resistance as they combine the carbide with the antioxidant properties of the boride. This combination is essential for hypersonic cars. Xiong Xiang said that the promising candidates were for the parts.

Nature Communications published on 15 June the results of research conducted by the team. The State Key Laboratory of Powder Metallurgy of Central South University was the first unit to complete the thesis. Zeng Yi and Professor Xiong Xiang are the first correspondents. First author is the doctor. The University of Manchester (UK), a partner unit of the University of Manchester, UK characterized the material and performed an analysis.

After publication, the article attracted a great deal of interest from the foreign media and academic circles. The downloads of the article exceeded 5,000 in the three days immediately following publication. The Daily Mail in Britain, The Economist in the United States and Public Machinery (Russia) have all covered the research. . According to the reviewer in Nature Newsletter, the above research results "will ignite the academic excitement and interest in applying quaternary materials in hypersonic fields, because this material system represents a promising one."

The team began working with Professor Chang Xiang in 2002 with the help of the National 863 and 973, as well as the National Natural Science Foundation. They were led by a Yangtze River scholar, Professor Chang Xiang. Find a new ultra high temperature ceramic coating that has excellent oxidation resistance, and resistance to ablation. During the research, dozens and hundreds of high temperature materials were screened, from silicon carbide through strontium carbide and titanium carbide. It has taken 15 years to achieve the breakthrough of developing new ablation-resistant coatings in 3000 degC ultra high temperature environment.

Knowing the interesting chemical elements boron B comes from afar

Boron has been a major name in the world of chemistry. There have been two Nobel Prizes in Chemistry for the work done on boron.

There are boron-containing glasses and washing powders on the market. They contain boric acid in the glass to prevent it from expanding or contracting after joining.

Diamond is the hardest substance known to man. However, recent theories suggest boron-nitride in alternate forms, wurtzite, may actually be more hard than diamond. But these crystals have yet to be synthesized.

Boron compounds have a number of interesting properties. They play a crucial role in polymer crosslinking, which gives plasticine a remarkable ability. It is soft and malleable when held in your hands but becomes hard and elastic if you throw it at a wall.

Boric acid is a compound that contains boron and it's often used as a medicine or to kill insects. Boric Acid can be used for eye disinfection, especially in high school and middle school chemistry laboratories.

What metal can withstand higher temperatures than tungsten

What metal is more resistant to heat than tungsten?

The melting point for tungsten, which is 3,422°F (boiling at 5,930°F), is the highest of all metal elements on the periodic table. No metal element is higher in melting point than the tungsten.

Tungsten is element number 74 in the VIB Group of Period 6. Each atom has the ability to form six metal bond.

There are elements that are more resistant to heat than tungsten. Solid carbon, for example, can be heated up to 3,627 degrees c. However, carbon does not have a fixed melting temperature (one atmosphere), because it sublimates between 3627 and 4330 degrees c.

Ta4HfC5 is the heat-resistant material that humans have produced so far. It has a melt point of 4215. It's made from tantalum carbide and hafnium carbide (melting point nearly 4000), both of which have higher melting points than tungsten.

The melting point of a material is dependent on its pressure. The higher the pressure the higher it will be. But when temperature and pressure exceed critical levels, the material becomes superfluid, losing its melting point.

Nano silver substitution trend is irreversible

Nanowires to replace infrared first
Due to the rapid growth of the display industry, as well the high processing costs of ITO films and the limited indium resources, the industry has looked for alternatives, such as nanowires. Silver nanowires, among other alternatives, are the most advantageous due to their technology and maturity. Additionally, they are flexible and can be used to replace other materials that conduct electricity with flexible displays of east winds.

Nanosilver has the most important role in Nanosilver. Nanosilver has the best antibacterial properties.

"With the present process, silver nanowires are first to be used on a large scale as an alternative for infrared touchscreen technology. Du said, ""The substitute is already obvious." "The large-size products made of silver nanowires are gaining customers' recognition.

Currently, infrared control is used mainly on the market for electronic whiteboards. Infrared transmitter tube and receiving tube is arranged on the raised border so that infrared optical networks are formed.

The next big flashpoint is 2020

The global smartphone market, with its huge population, has slowed down. However, the small and mid-sized markets will be essential for silver nanowires' mainstream adoption.

"The smartphone industry needs revolutionary innovation, whether it's facial recognition, the full screen or the hot AI feature," du said. ""Whether it is facial recognition, a full-screen, or the latest AI feature, the industry needs revolutionary innovations," du said.For the moment, foldable phones make sense. As screens get bigger, they become more difficult to handle. Foldable screens also offer a new market for product experiences.

The last step to breaking through the nanowire

The technology of silver microwires is not widely used. The production, manufacture, storage, and patent of the silver nanowires is considered to be an important factor that limits their development.

It is not possible to replace ITO conductive film with silver nanowires. The future holds the biggest potential for completely new applications.

Molybdenum disulfide nanoelectromechanical system ultra-thin ultra-small ultra-low power consumption

Graphene, a typical material with two dimensions, is widely used and highly sought-after by scientists and the industry. What exactly is a 2-dimensional material? Simple, two-dimensional material is a non-nanoscale (between 1 and 100 nm) material in which electrons are able to move freely in two directions (planar movement). Examples of such materials include: graphene; boron nitride; transition metal compounds, (disulfide); Molybdenum; tungsten diulfide; tungsten silicidide, black phosphorus.
2D materials can be used in a variety of fields. In combination with the authors' previous introductions, some examples include: spintronics (printed electronics), flexible electronics (microelectronics), memory, processors and hyperlenses. , quantum dots, sensors, semiconductor manufacturing, NFC, medical, etc.


Molybdenum diulfide, also known as MoS2, is a two-dimensional material that deserves our attention. Molybdenum diulfide, which is composed of two atoms of molybdenum with one atom of sulfur, has only three atoms of thickness. Molybdenum diulfide and graphene are almost identical in thickness, however, molybdenum diulfide's band gap is 1.8 eV whereas graphene has no band gap. The author of this article once stated that the US Department of Energy Berkeley Lab had accurately measured band gap of semiconductor two-dimensional materials molybdenum sulfide and revealed a powerful tuning mechanism.


In addition, the molybdenum diulfide has an electron mobility that is 100 cm2 /vs. (ie. 100 electrons per centimeter square per volt), although it's much lower than crystal. The silicon has an electron transfer of 1400 cm2/vs but has a higher migration rate than ultra-thin semiconductors and amorphous silica.

Molybdenum diulfide, with its excellent semiconductor characteristics and small size and ultra-thinness, is ideal for use in flexible electronics, solar cells, LEDs and lasers.

Tungsten Oxide Insulation Material Can Make The Sun Room Cool in Winter and Cool in Summer

What is tungsten Oxide?Tungsten dioxide has the molecular formula WO3 with a weight of 2318.5.
It is a form of tungsticanhydride. Tungsten dioxide is not produced in industrial production. According to the amount of tungsten, the tungsten-trioxide salt can be divided into tungstic acids, sodium tungstates, calcium tungstates, ammonium paratungstates, ammonium métatungstates, etc.
Tungsten Trioxide is a powder crystal of pale yellow triclinic. Once the temperature reaches 740 deg C it changes into an orange tetragonal crystalline. In air, it is stable, with a melting point of 1473 deg C and a boiling point higher than 1750.
Tungsten Trioxide is one of the most stable tungsten oxydes. It is not soluble in water or inorganic acid other than hydrofluoric. It is soluble with hot sodium hydroxide solution, ammonia and a concentrated sodium chloride solution to form soluble tantstate. If the temperature is greater than 650 deg C it can reduce by H2, but at 1000-1100 C it can reduce by C to get tungsten.

The application of tungsten dioxide transparent insulation material
Smart homes make home life safer, more comfortable and convenient. The smart home also saves energy and is environmentally friendly. So, it's not surprising to see the smart sun room. The so-called "intelligence", one of them, is to break the room in summer like "fire stove", winterlike a refrigerator. Transparent semiconductor materials like tungsten oxide transparent materials are a good way to make the sunroom cool in summer and warm in winter. My opinion is that it's not necessary to install floor heating and air conditioning equipment. The best solution to heat insulation is to start at the source.

This concept of smart homes has already permeated our minds and is being applied everywhere! Unfortunately, this author hasn't been able live an intelligent lifestyle. This led to the classic home scene: the author would go out and come back halfway. Then, she'd remember something, did I lock my door? Is your air conditioner turned off? If you don’t go back to confirm, you won't make it through the day. But go back, and you'll be late to work! What about changing to the smart home scenario? ----Set the home scene to unmanned after locking the door. Turn off all power supplies to the terminal blocks and confirm home status anytime through the mobile application. It is easy to use, and it makes people feel more at ease.
The switch to a smart room can also be compared. Now, Low-e is used in some sunrooms. Researchers tested the blocking of ultraviolet rays and near-infrared radiation by glass coated with nano tungsten oxide, Low-e, glass with heat insulation film, hollow-tempered glass, and single sided glass. The glass coated with nano-tungsten dioxide has an infrared blockage rate of 91%. 2. Low-e glass has an infrared blocking percentage of 62.8% and a UV blocking percentage of 56%. 3. The infrared blocking percentage of glass with heat-insulating films is 59%, while the ultraviolet blocking percentage is 99.7%. 4. Hollow tempered glasses have an infrared-blocking rate of 34.2%, and a ultraviolet-blocking rate of 23.5%. 5. The infrared blocking percentage of single-sided glasses is 12.4%, and the ultraviolet blocking percentage is 13.5%.

As can be seen by the data, single-sided tempered glass with a nano-tungsten coating is the best for blocking infrared; and single-sided tempered glass with a thermal insulation film with nano tungsten is the best for blocking ultraviolet. Coated single-sided glass. Industry insiders say that because UV light is bactericidal and most people want to take pictures of the sun, having a high UV-blocking rate can be harmful. Solar radiation is known to provide energy for life on Earth. The amount of infrared, ultraviolet, and other rays that are present in sunlight is important. In general, the scientifically-recommended permeability rate is around 10%. In terms of health and energy savings, using nano-tungsten oxide coated insulation glass is the most effective.

It is clear that tungsten oxide is a transparent insulation material with two issues to solve urgently when building energy-saving windows: Transparency is defined as the ability to transmit light. It also meets lighting requirements. High barrier for the near infrared. This reduces energy consumption by blocking the sun's radiant energy.
Moreover, the tungsten-oxide transparent heat insulating film is an environmentally friendly, water-based material that can be painted to a thickness as low as a few nanometers. This allows it to enjoy the "warm winter" and the "cool summer" effects without opening the air conditioner. The tungsten oxide transparent heat insulating material is also a great option for insulation. . These materials include tungsten bronze as well as ITO, ATO FTO.
Tungsten-oxide insulation is not an "evil technology" but rather a result of technological and scientific development. According to the author, in today's advocacy for "energy conservation and emission reduction", as well as "taking the path towards sustainable development", these transparent insulation materials will receive more and greater attention.
