Photochromic materials refer to a class of materials that can change color after being excited by a light source. The first successful commercial application of photochromic materials began in the 1960s. Subsequently, a lot of research was done on its mechanism and application. Later on, color-changing glasses were developed. Photochromic compounds can generally be divided into two types: organic and inorganic. The first developed photochromic compounds are mainly organic compounds, and their photochromic activity mainly comes from the color change caused by bond cleavage, reorganization or conformational change. Among them, the basis of molecular motors, photo-induced cis-trans isomerization, is a typical system in the field of photochromism. In addition, spiropyran can hetero-cleavage the carbon-oxygen bond under UV irradiation to produce cyanine compounds that can be photoexcited to open the ring, which is a typical bond-cleavage photochromic system. In addition, salicylaldehyde ani...

N ever forgetting  its mission to bring cost-effective yet high-quality materials to customers worldwide, earlier this year the US-based chemical supplier Alfa Chemistry has   successfully introduced a new product line of  alternative and renewable energy materials.   Considering the vital role these materials play, the company recently also demonstrates its proven capability in thermal analysis   for the testing of  materials to be used in the alternative energy industry. Thermal analysis is purposed to   measure how materials ’   physical, mechanical, chemical, and thermodynamic properties will change under differing temperatures and loads, and help to   pinpoint when and at what temperature significant changes may occur.   As the world is increasingly demanding for a cleaner environment , more and more renewable energy sources   such as solar energy, wind energy or biomass plants , have been developed . “ Our group of specialists...

As a reliable source for versatile catalysts, Alfa Chemistry Catalysts today   announces  that it has launched a rich of collection of asymmetric organocatalysts , including chiral amines, chiral amino acids, chiral ammonium salts, chiral bicyclic guanidines, chiral diols, chiral imidazolidinones, chiral isothioureas, chiral n-heterocyclic carbenes ( NHC ), chiral oxazaborolidines, chiral sulfonic acids, cinchona alkaloids, and prolines, proline analogs. All  can be used to accelerate different types of chemical reactions  for research and production , whereas all are of high purity and of high-popularity   among  consumers. The efficacy and synthetic versatility of asymmetric organocatalysis have contributed to the huge achievements in resolving enduring synthetic challenges  of stereochemical relevance as well as discovery of new catalytic modes, reaction types and advantageous integration with disparate reaction types.   “Simply put, a symmetri...

The past decade has witnessed the advent of a new recycled plastics revolution. As a supplier of functional polymers, Alfa Chemistry   recently announces that it is starting to offer recycled plastic products   for customers who are interested in saving resources and protecting the environment   by doing so. Using the r ecycled plastic as  raw material , and together with physical or chemical methods like  pretreatment, melting granulation and modification , plastic   products can be re-produced for use in manufacture or research. “ Overall, t he prospect of recycled plastic is broad . It ’ s not just about turning  the waste into treasure, but more about truly achieving environmental protection and energy saving , ”   says the Marketing Chief of Alfa Chemistry . “ Another evident advantage for the recycled plastic   is their cheaper price, which increases their popularity among both manufacturers and consumers. We can provide professional pr...

E merged as important players in modern medicine   and many other fields , n anoparticles   are now at the center of research for various   applications . As a leading supplier of nanomaterials, Alfa Chemistry   announces its ability to provide varieties of n anoparticles   for use in both academia and industry manufacturing, including oxides nanoparticles, nanopowder compounds, alloys nanopowders, nano dispersion, mineral trioxide aggregate (MTA), magnetic nanoparticles, graphene nanopowders, elements nanoparticles, doped nanoparticles, compounds nanoparticles, clay nanopowders and more. N anoparticles range from 1 nm to 1000 nm   in size. Because of their properties   in chemical reactivity, energy absorption, and biological mobility , they are very different from bulk materials . Having gained a position at the core of all forms of nanobiomaterials , n anoparticles   have found broad prospects in catalysis, imaging, biomedicine , energy-based r...
