Recent advances in photocatalytic hydrogen peroxide production

open access: yesPhotoMat, EarlyView., 2023
We classify the representative photocatalytic materials for photosynthesis of hydrogen peroxide (H2O2) in recent years and discuss the related modification methods in detail, providing inspiration and insights for the future design of photocatalysts for H2O2 production.

Tunable Oleo-Furan Surfactants by Acylation of Renewable Furans

open access: yesACS Central Science, 2016
An important advance in fluid surface control was the amphiphilic surfactant composed of coupled molecular structures (i.e., hydrophilic and hydrophobic) to reduce surface tension between two distinct fluid phases. However, implementation of simple surfactants has been hindered by the broad range of applications in water containing alkaline earth ...

Potential Antagonistic Effects of Acrylamide Mitigation during Coffee Roasting on Furfuryl Alcohol, Furan and 5-Hydroxymethylfurfural

open access: yesToxics, 2018
The four heat-induced coffee contaminants—acrylamide, furfuryl alcohol (FA), furan and 5-hydroxymethylfurfural (HMF)—were analyzed in a collective of commercial samples as well as in Coffea arabica seeds roasted under controlled conditions from very ...

Encapsulation of ascorbic acid promotes the reduction of Maillard reaction products in UHT milk [PDF]

open access: yes, 2016
The presence of amino groups and carbonyls renders fortified milk with ascorbic acid particularly susceptible to the reduction of available lysine and to the formation of Maillard reaction products (MRPs), as Nε-(Carboxyethyl)-L-lysine (CEL), Nε ...

Synthesis, Characterization, Biological Properties, and Sensor Applications of Novel Thiosemicarbazone Derivatives

open access: yesBiotechnology and Applied Biochemistry, EarlyView.
ABSTRACT In this study, novel thiosemicarbazone derivative molecules (5a–j) were synthesized. The characterization of the synthesized molecules was carried out using 1H–, 13C–NMR, FT–IR, and Q–TOF spectroscopic techniques. Then, the inhibitory effect of these compounds was examined for human carbonic anhydrase I and II (hCA I, and II) and ...

Liquid crystalline properties of unsymmetrically substituted phthalocyanines: structural features leading to nematic mesophase materials [PDF]

open access: yes, 2014
A novel homologous series of four 1,4,8,11,15,18-hexakis(pentyl)-22-methyl-25-hydroxyalkylphthalocyanine derivatives with the hydroxyalkyl chain varying from hydroxynonyl through to hydroxydodecyl has been synthesized to investigate the role of the ...

Effective acetalization of furfural catalyzed by Fe‐ and Co‐oxalates: impact of alcohols structure on products composition

open access: yesBiofuels, Bioproducts and Biorefining, EarlyView.
Abstract Fe‐, Co‐, and FeCo‐oxalates supported on silica gel (5 wt% metal load) were synthesized, characterized, and tested for the first time in solvent‐free furfural (FF) acetalization with C1–C8 alcohols at 70–170 °C under both conventional and microwave (MW)‐assisted conditions. The interaction of FF with linear C1–C4 alcohols yielded pincer‐shaped
