Three laccases, functioning in mild acidic, and one in slightly alkaline conditions, were evaluated in order to reduce low-molecular phenolic VOCs of kraft lignins, which could be used in lignin/natural fibers composites. The potential of a sulfhydryl oxidase to catalyze the oxidation of sulfur containing VOCs (thiols) was also tested in combination with the laccase-catalyzed oxidation. In addi...

Conjugated linoleic acid (CLA) is a mixture of positional and geometric isomers of octadecadienoic acid with conjugated double bounds. Positive health properties have been attributed to some isomers, such as anticarcinogenic activity, antiartherosclerotic effects and reduction of body fat gain. Hence, oils rich in CLA such as Tonalin(®) oil (TO), normally obtained through alkaline isomerization...

Polyols and polyacrylates have a wide range of applications in polymer synthesis as monomers, initiators, or building blocks variety polymerization reaction types. With an ever-growing need to reduce the global dependency on fossil fuels, finding bio-based/renewable sources for these compounds is now critical. Herein, alkene moieties common, abundant terpenes are functionalized via oxidation ex...

Abstract Plasma fibrinogen is an important coagulation factor and susceptible to post-translational modification by oxidants. We have reported impairment of fibrin polymerization after exposure hypochlorous acid (HOCl) increased methionine oxidation in severely injured trauma patients. Molecular dynamics suggests that poses a mechanistic link between oxidative stress through protofibril lateral...

Two series of well-defined lignin fractions derived from birch and spruce alkaline (AL) by sequential solvent fractionation (i-PrOH-EtOH-MeOH) were engaged in a structure–property-application relationship study. The bacterial-derived alkaliphilic laccase (MetZyme) extensively catalyzed the oxidation polymerization AL an aqueous solution (pH 10). Lignin with low molar mass reached higher degree ...

Traditionally, wool fibers are dyed with acid dyes at the boil, which is energy-intensive process, and increases cost of dyeing. The development alternative energy-efficient dyeing processes quite attractive to textile industry make sustainable. In this work, feasibility low-temperature fabric several aniline sulfonic (ASA) derivatives by oxidative polymerization method was investigated. effect...

Invited for this month's cover picture are Hikaru Iwami, Mio Kondo, and Shigeyuki Masaoka at Osaka University. The illustrates catalytic water oxidation by electrochemically deposited Ru complex polymer bearing carbazole moieties. catalyst exhibited excellent charge transporting ability, which was found to be a key the efficient reaction.

In this study, first a hydrogel based on sodium alginate and acrylamide was prepared by radical polymerization method then manganese oxide formed in its lattice structure nanocomposite hydrogels were obtained. the next step, Nanocomposite used as catalysts for oxidation of alcohols. To evaluate physical properties confirm hydrogels, Hydrogel swelling tests, FT-IR infrared conversion spectroscop...

• Metallocalix[ n ]arene complexes as catalysts in numerous catalytic reactions. The presence of the calixarene cavity allows for enhanced enantioselectivity. Cross-coupling, olefin oxidation and polymerization processes are most studied. Increased attention to ROP cyclic esters produce biodegradable polymers. Large flexible calix[ ]arenes can adapt energy requirements a process. Aside from the...
