Polymer Nanogels with Albumin Reporting Interface Created Using RAFT Precipitation Polymerization for Disease Diagnosis and Food Testing

Advanced Materials Interfaces, EarlyView.
Herein, polymer nanogels with a reporting interface for albumin are synthesized through reversible addition–fragmentation chain transfer (RAFT) precipitation polymerization of di(ethylene glycol) methyl ether methacrylate and N,N’‐methylenebis(acrylamide) using a poly(2‐methacryloyloxyethyl phosphorylcholine) macro‐RAFT agent, followed by dansyl ...

A procedure for the determination of proteolytic activity [PDF]

, 1950
The difficulties introduced by the desire to maintain a constant pH during an enzyme-catalyzed hydrolysis of peptide-like substrates and at the same time to determine the extent of hydrolysis by an acid-base titration have been pointed out (1), but to ...

Synthesis and Structure-Activity Relationships of Pyridoxal-6-arylazo-5'-phosphate and Phosphonate Derivatives as P2 Receptor Antagonists. [PDF]

, 1998
Novel analogs of the P2 receptor antagonist pyridoxal-5'-phosphate-6-phenylazo-2',4'-disulfonate (PPADS) were synthesized. Modifications were made through functional group substitution on the sulfophenyl ring and at the phosphate moiety through the ...

Electrophotocatalytic Hydroxymethylation of Azaarenes with Methanol

Organic Letters
The merge of electrochemistry and photocatalysis allowed the required selectivity for the hydroxymethylation of functionalized azaarenes with methanol, including bioactive substrates. The two electrophotocatalytic protocols developed in this work address this transformation, using non-toxic and readily available reagents under mild reaction conditions ...

How to Manufacture Photonic Metamaterials

Advanced Materials Technologies, EarlyView.
Metamaterials boast applications such as invisibility and “hyperlenses” with resolution beyond the diffraction limit, but these applications haven’t been exploited in earnest and the market for them hasn’t grown much likely because facile and economical methods for fabricating them without defect has not emerged.

Corrosion studies on Fe-30Mn-1C alloy in chloridecontaining solutions with view to biomedical application [PDF]

Materials and Corrosion 69 (2018) Nr. 2, S. 167-177, 2019
Austenitic Fe-30Mn-1C (FeMnC) is a prospective biodegradable implant material combining high mechanical integrity with adequate corrosion rates. The fast solidified TWIP alloy, its constituents and 316L stainless steel were electrochemically analysed in various electrolytes at 37 {\deg}C under laminar flow.

Dearomative, Intramolecular Bromoetherification of Carbohydrate‐derived Glycosyl Furans: Access to Enantiopure 6‐Bromo‐Furo[3,2‐b]furans

Advanced Synthesis &Catalysis, EarlyView.
Abstract Glycosyl furans represent versatile chiral platform molecules that can be readily accessed via the Garcia Gonzalez reaction. Herein, we report a dearomative, intramolecular bromoetherification of carbohydrate‐derived glycosyl furans to generate enantiopure 6‐bromo‐furo[3,2‐b]furans in up to 69% yield. The method employs N‐Br aromatic amides as

XPS Supported INS and DRIFT Spectroscopy of sp2 Amorphous Carbons [PDF]

arXiv, 2019
We carried out a joint analysis of the INS, DRIFT, and XPS spectra of a set of sp2 amorphous carbons of the highest carbonization rank representing natural substances (shungite carbon, anthraxolite, and anthracite), technical graphenes (laboratory reduced graphene oxides), and industrial products (carbon blacks).

Oxidation products of 5-methyl cytosine are decreased in senescent cells and tissues of progeroid mice [PDF]

, 2018
5-Hydroxymethylcytosine and 5-formylcytosine are stable DNA base modifications generated from 5-methylcytosine by the ten-eleven translocation protein family that function as epigenetic markers. 5-Hydroxymethyluracil may also be generated from thymine by
