Long-lived enzyme catalysts are produced by chemically cross-linking the enzyme crystals.Reports on the production of long-lived enzyme catalysts by chemically cross-linking the enzyme crystals. Study by J.J. Lalonde and colleagues.D.L.N.
Enzymes are protein catalysts that accelerate a chemical reaction and are not used up or changed during the reaction. They are able to do this by binding to the substrate, a specific substance the enzyme interacts with, and lowering the activation energy needed to undergo the reaction. The subs...
it is hard to regulate the intracellular delivery to a target organelles. Right here we report an intracellular delivery system of nanoparticles changed with microbial cytotoxins towards the endoplasmic reticulum (ER) and anti inflammatory activity associated with the nanoparticles. Subtilase cytotoxin (Sub...
Plastic resins are made by polymerizing one or more monomers in the presence of additives such as antioxidants, initiators, catalysts, thermal stabilizers, etc. More chemicals such as other antioxidants, thermal stabilizers, plasticizers, impact modifiers, clarifiers, colorants, mold release agents and...
Metal homeostasis imbalance has been observed in brains of HD patients, and since they are catalysts that induce the production of free radicals, they are believed to participate in the progression of the disease [106]. In this regard, iron and copper accumulation has been observed in HD patien...
Driers and catalysts. They allow for the acceleration of the drying process of the paints. Dryers are generally organometallic compounds, where the active part (the metal) is generally represented by cobalt and manganese (primary dryers), lead, calcium, zinc, zirconium, and barium (secondary dryer...
An example is represented by a nanocomposite coating made of single-walled carbon nanotubes (SWCNT) and a series of waterborne polyurethane-urea dispersions (WPUD) free from tin catalysts and harmful solvents. The obtained WPUD are made of 100% bio-based semi-crystalline polyester polyol (Prip...

Work function, carrier type, and conductivity of nitrogen-doped single-walled carbon nanotube catalysts prepared by annealing via defluorination and efficient oxygen reduction reaction. Carbon 2019, 142, 518–527. [CrossRef] 30. Yokoyama, K.; Mamiya, I.; Morita, H.; Sato, Y.; Nishida, T.;...
Generally, biobased polymers are classified into three classes: • 1st class; naturally derived biomass polymers: direct use of biomass as polymeric material including chemically modified ones such as cellulose, cellulose acetate, starches, chitin, modified starch, etc.; • 2nd class; bio-...
