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 a few heat-resistant products on the market that have added boric acids to common glass. This means the glass will not expand or contract easily after joining.

Diamond is the hardest substance known to man. However, recent theories suggest wurtzite, an alternate form of boron, may be harder. However, the crystals for this compound have not been created yet.

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 labs.

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 in advance. 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, another BE PM-Ti 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 low 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 formula of B4C. The powder is typically grayish. It is one the three hardest materials known (the other two being diamond and cubic boronnitride), which are used in many industrial applications, including tank armor, torso armor, and body armor. It has a Mohs toughness of 9.3. A large number of tests were conducted by the team of the 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 the development hypersonic cars.

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 sound. With such high speeds, the flight between Beijing and New York could be completed in just 2 hours - provided the aircraft's key structural components can handle severe air friction as well as hot air impacts of 2000-3000 deg. C. . Central South University has developed ceramic composite materials and coatings for ultra-high temperatures that provide better protection of the above components. The world's very first synthesis of a single-phase quaternary carbide ultra-high-temperature ceramic material with boron is being reported. This coating is a perfect "fusion" between carbon-carbon-based materials. The current focus of research in the area of new materials is on the mixed materials of binary compound system. The successful application of materials quaternary to hypersonic will be greatly facilitated by its development.

The novel ceramic coated modified carbon/carbon material is composed by a single-phase carbide of zirconium (quarterary), titanium, carbon, and boron. It has a stable carbide-crystal structure. Infiltration of a multiceramic phase is the main method for obtaining it. The ultra high temperature ceramic combines the high-temperature adaptability of carbides and the anti-oxidation property of borides. This makes the coatings, composites, and other 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 and gradient ceramic coatings, all of which make the ceramic a lighter material. Ablation loss rate.

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

Nature Communications published on 15th June the results of research conducted by the team. The State Key Laboratory of Powder Metallurgy of Central South University was the first completion unit of this 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. In the three days immediately following publication, this article was downloaded over 5,000-times, whereas other articles were only downloaded 300 to 900 times. 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 results will ignite academic excitement and interest in applying quaternary materials in the field of hypersonics, because it represents a very promising system of material."

The team has been working on anti-oxidation coatings for carbon/carbon composites since 2002. This was done with the help of the National 863 and 973, as well as the National Natural Science Foundation. Professor Chang Xiang is the leader of this project. Find a new ultra high temperature ceramic coating that has excellent oxidation resistance, and resistance to ablation. In the course the research, dozens and hundreds of high-temperature material systems were screened, from the initial strontium carbide through to zirconium and zirconium boride. tantalum and tantalum carbide. It has taken 15 years to achieve the breakthrough of developing new ablation-resistant coatings in 3000 degC ultra high temperature environment.

Controlling the electronic state of two-layer molybdenum disulfide in an origami manner

In recent years, transition metal dichalcogenide was one of the key two-dimensional materials for quantum functional applications. These materials have a honeycomb like graphene but have spin-orbit coupling that allows them to exhibit novel properties. As an example, molybdenum isosulfide's energy band structure evolved from a multilayer to monoatomic layer from an indirect band to a directly band, which improved fluorescence efficiency. It is important to understand the mechanisms behind these quantum phenomena in order to manipulate them. This will be of great benefit to condensed matter science and future electronics and optoelectronics.
Professor Wu Shiwei claims that the concept behind this work is the "ultra thin" nature of the two-dimensional quantum functional material: the monoatomic layers are folded like paper to create a second layer that is not possible by natural epitaxial growth or crystallization. Layer structure. Molybdenum Disulfide “origami” has many interlayer arrangements depending on the direction and location of the fold line. This in turn results in different macrostructure symmetry, and interlayer coupling. The research team combined first-principles computations with various experimental techniques including fluorescence spectroscopy and optical depolarization to study the electronic and space structures of various molybdenum "origami".
In addition, the change of interlayer coupling not only can greatly affect indirect band gaps in molybdenum-disulfide "origami", but it can also be used to switch the relationship between spine and electron spin when "folding the paper". Changes in interlayers can affect not only the indirect band gap, but also the relationship between spine and electron spin. This work provides an experimental platform that allows for the manipulation of interactions between multiple degrees of free will, including valley, spin and interlayer coupling.

Nano silver substitution trend is irreversible

Nanowires to replace infrared first
Due to the rapid growth of the display industry, as well the high cost and shortage of ITO films and indium, 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 a flexible display for east wind.

Nanosilver has the most important role in Nanosilver. Nanosilver has excellent antibacterial properties and is safe.

"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.

Infrared is the main touch control technology used in 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 begun to slow. However, the small and mid-sized markets, due to their large base of users, are also vital for silver nanowires technology to become mainstream.

"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 new AI feature, smartphone innovation needs to be revolutionary," du said. For now, foldable smartphones are a good thing.

The last step to breaking through 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 films with silver nanowires. Future application scenarios will offer the biggest opportunities.

What metal can withstand higher temperatures than tungsten

What metal is more resistant to heat than tungsten?

Among all metal elements, tungsten's melting point is the highest, at 3,422. (Boiling point: 5,930). No metal element is higher in melting point than the tungsten.

Tungsten is the element 74 in the VIB Group of the 6th Period of the Periodic Table. This means that every atom is capable of forming six metal bond.

There are elements that can be heated higher than tungsten. Solid carbon can reach temperatures as high as 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 (which has a melting point of 4000), both of which are more heat resistant 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.

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

As a typical material with two dimensions, graphene is widely used and highly sought-after by both industry and the scientific community. What exactly is a 2-dimensional material? Simple, two-dimensional material is a non-nanoscale material (1-100nm) where electrons are able to move freely in two directions (planar movement). Examples of this include: graphene and other transition metal compounds, Molybdenum disulfide or disilicide, tungsten, black phosphorus etc.
2D materials can be used in a variety of fields. Following the introductions by the authors, some examples include: spintronics (printed electronics), flexible electronics, microelectronics (microelectronics), memory, processors and hyperlenses. , quantum dots, sensors, semiconductor manufacturing, NFC, medical, etc.


Molybdenum diulfide, also known as MoS2, is a typical 2-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. The graphene thickness is nearly the same as molybdenum, but graphene has no band gap. The author of this article once stated that the US Department of Energy Berkeley Lab's research team 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 migration rate of about 1400 cm2/vs. However, it is better than amorphous silica and other ultra thin semiconductors.

Molybdenum diulfide, with its excellent semiconductor characteristics and small size and ultra-thinness, is ideal for transistors, flexible electronic devices, LEDs, Lasers, and Solar Cells.

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. The tungsten-trioxide salts are classified according to their content in tungsten dioxide.
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 acids except hydrofluoric. It is soluble with hot sodium hydroxide solution, ammonia and hot concentrated sodium chloride to form soluble tantalate. If the temperature is greater than 650 degrees C, H2 can be used to reduce it. At 1000-1100 degrees C it can also be reduced with C.

The application of tungsten dioxide transparent insulation material
Smart homes make home life safer, more comfortable and more convenient. The smart home also saves energy and is environmentally friendly. So, it's not surprising to see the smart sunroom. One of these is the so-called "intelligence", which breaks the sun room into two parts: summer as "fire stove", and winter as "refrigerator". Transparent semiconductor materials like tungsten oxide transparent materials are a good way to make the sun room 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 in the sunroom is to start at the roots.

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 left the house every time. The result was that he forgot something, but remembered it halfway. Is your air conditioner turned off? You cannot survive the day if you do not go back to confirm. But go back, and you'll be late to work! What about changing to the smart home scenario? ----After you lock the front door, turn the scene to unmanned, shut off the power of the terminal blocks, and check the status from the app at any time. It is easy to use, and it makes people feel more at ease.
The switch to a smart room can also be compared. Low-e glass is now 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, single-sided glass and glass coated with hollow tempered. They found that: Infrared blocking rates of the glass coated with nano-tungsten dioxide are 91%, and ultraviolet blocking rates are 91%. 2. Low-e glass has an infrared blocking percentage of 62.8%, and a UV blocking percentage of 56%. 3. Infrared rays are blocked 59% by the heat-insulating glass. UV rays are blocked 99.7%. 4. Hollow tempered glasses have an infrared-blocking rate of 34.2%, and an 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 nano tungsten oxide coating has the best infrared blocking ability. Single-sided tempered glass with thermal film and nano tungsten oxide have the most effective ultraviolet blocking ability. Single sided glass that is coated. 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. It is widely known that solar energy provides the necessary energy to sustain all human life. 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 best.

It is clear that tungsten oxide is a transparent insulation material with two issues to solve urgently when building energy-saving windows: High transparency is defined as high transmittance of visible light and meeting lighting requirements. High barrier for the near infrared. This reduces energy consumption by blocking the radiant sun's energy.
This transparent tungsten-oxide heat insulating film is an environmentally friendly, water-based material that can be painted to a thickness as low as a few nanometers. It will then give the impression of "warm summer and cool winter" without the need for air conditioning. This kind of insulation also offers excellent safety features (if the glass breaks, there will be no glass slag), privacy protection, stain-resistance, self-cleaning capabilities, anti glare and anti radiation. . 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.
