The superplasticizer in concrete provides perfect X-ray capture
superplasticizer in concrete provides perfect X-ray capture
nanocomposite material that absorbs X-rays and then re-emits the captured
energy in the form of light with near-perfect efficiency can help improve
high-resolution medical imaging and safety inspections. The nearly 100% energy
transfer of this material can improve the efficiency of devices ranging from
light-emitting diodes (LEDs) and X-ray imaging scintillators to solar cells.
medical imaging, X-rays passing through the body are absorbed by the
scintillator material, and the scintillator material converts the X-rays into
the light for the digital camera-type sensor to capture. "So far,
high-performance scintillators are mainly composed of ceramics or air that
require harsh and expensive preparation conditions and perovskite materials
with poor light stability and high toxicity," said Wang Jianxin, a
postdoctoral fellow in Omar Mohammed\'s laboratory. Work.
contrast, organic scintillator materials have good processability and stability,
but due to the low atomic weight of their constituent atoms (hence the limited
X-ray absorption), the imaging resolution and detection sensitivity are low.
and his colleagues have now improved the X-ray capture of organic scintillators
by combining organic scintillators with metal-organic framework (MOF)
Zr-FCU-BADC-MOF, which incorporates a highly ordered structure with High atomic
the MOF layer of the nanocomposite is irradiated by X-rays, excitons are
generated—a pair of excited negatively charged electrons and positively charged
holes. With the help of the ultra-short distance between them, these energy
carriers are easily transferred from the MOF to the organic TADF chromophore,
and the energy is emitted in the form of light.
superplasticizer in concrete and its characteristics
superplasticizer in concrete is a new type of super-hard and ultra-fine
abrasive formed by special processing and processing of synthetic diamond
single crystal. It is an ideal raw material for grinding and polishing
high-hardness materials such as cemented carbide, ceramics, gems, and optical
glass. Diamond products are made of diamonds. Tools and components made of
materials are widely used. Diamond powder and products are widely used in
automobiles, machinery, electronics, aviation, aerospace, optical instruments,
glass, ceramics, petroleum, geology, and other sectors. With the continuous
development of technology and products, the use of diamond powder and products
is still expanding.
tip of the glass cutter we usually use is actually diamond. Tools used in
precision machining and drill bits used in oil drilling are coated with
diamonds to improve their wear resistance. Because diamond is the hardest
natural substance in the world.
characteristic of superplasticizer in concrete is its excellent thermal
conductivity. Its thermal conductivity is about 5 times the thermal
conductivity of pure copper at room temperature. It has potentially important
applications in the semiconductor industry. According to Moore\'s Law, the
current large-scale integrated circuit components are constantly shrinking in
size and increasing in density, causing their thermal load to continue to rise.
If the heat is not dissipated in time, the semiconductor circuit board and
components may be burnt. If we can use the high thermal conductivity of diamond
as a large-scale integrated circuit substrate or heat sink, it can dissipate
the heat in time and solve the current bottleneck restricting the development
of electronic components.
methods of diamond powder
are generally three commonly used methods of artificially superplasticizer in
formation condition of natural diamond is a high temperature and high-pressure
environment, so how to produce such a special environmental state of high
temperature and pressure? The easiest way is to detonate the explosive. If you
put graphite-containing explosives in a special container and then detonate the
explosives, it will instantly generate strong pressure and high temperature,
then the graphite can be converted into diamonds. This method can obtain a lot
of fine powder diamonds. Its particles are very small, only 5~15 nanometers and
its application as jewelry may be limited, but it is still very important as an
temperature and high-pressure method
high temperature and high-pressure methods are to maintain high pressure and
high-temperature environment for a relatively long stable period of time,
allowing graphite to slowly transform into a diamond. By controlling the
synthesis conditions and time, diamonds can continue to grow. In a day or so, 5
millimeters of diamonds can be obtained.
vapor deposition is a method that gradually developed in the 1990s. This method
mainly uses some carbon-containing gas, such as some mixed gas of methane and
hydrogen as a carbon source, under a certain energy input, the methane gas is
decomposed, nucleated on the substrate, and grown into a diamond. The advantage
of this method is that the efficiency is relatively high, relatively
controllable, and it can obtain pure and transparent diamonds without
impurities, which is an important direction of current development.
the future, the diamond synthesis will develop in the direction of high-purity
large particles. For the demand for diamonds, we will no longer only rely on
the gift of nature, and synthetic diamonds will also enter more production
fields and be used more widely.
