Recent dramatic expansion in potential uses of protein conjugates has fueled the development of a wide range of protein modification methods; however, the desirable single-site multi-functionalization of proteins has remained a particularly intransigent challenge. Herein, we present the application of 5-hydroxy-1,5-dihydro-2H-pyrrol-2-ones (5HP2Os)...

Levoglucosan, mainly derived from cellulose fast pyrolysis, is a versatile precursor to fuels, pharmaceuticals, and other value-added chemicals. However, biomass fast pyrolysis produces a very low amount of levoglucosan when compared to the theoretical yield based on cellulose fraction. Microwave pretreatment of biomass in glycerol is a potential p...

Singlet-oxygen oxidation of 5-hydroxymethylfurfural (5-HMF) was performed in continuous flow mode using rose Bengal as photosensitizer. The resulting butenolide ((HMF)-M-2) was formed selectively in high yield. The procedure proved to be scalable and applicable to related bio-based furfurals. Furthermore, preliminary data show that (HMF)-M-2 can be...

[EN] The Sylvan (2-methylfuran) diesel process involves the conversion of pentose biopolymers into premium diesel via furfural, by means of hydroxyalkylation/alkylation and hydrodeoxygenation reactions. In the hydroxyalkylation/alkylation step two Sylvan molecules are reacted with an aldehyde or a ketone to yield C-12+ oxygenated intermediate molec...

The formation of 2-alkylfurans from the corresponding lipid-derived α,β-unsaturated aldehydes under dry-roasting conditions was investigated in detail. The addition of an amino acid to an α,β-unsaturated aldehyde drastically increased 2-alkylfuran formation. Peptides and proteins as well were able to catalyze 2-alkylfuran formation from the corresp...

An IRA-743 resin bulk sampler was validated to monitor long-term bulk deposition of polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs). Six consecutive sampling campaigns (2008-2009) were conducted at four sites around steel complexes in Pohang, South Korea to investigate spatial and seasonal variations of PCDD/F bulk deposition. The bul...

The distribution of polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs) was examined according to particle size in marine sediments, with a particular focus on fine particulates. Samples from different coastal sites were fractionated into five size groups (

This study describes the development of an emission measuring system for the quasi-continuous determination of polychlorinated Dibenzo-p-dioxins and Dibenzofurans in stack gases which have low dust concentrations. The emission measuring system consists of three components, a continuous operating sampler producing a stack gas condensate which contai...
