The Role of Organic Peroxides in the Induction of Mutations [PDF]

open access: yes, 1949
The discovery by Wyss, Stone, and Clark' that bacteria grown on a substrate recently exposed to ultra-violet light are subject to high mutation rates shows clearly that some meta-stable chemical substance, probably of no great complexity, is an ...

Flippase‐Mediated Hybrid Vesicle Division

open access: yesAdvanced Materials, EarlyView.
The successful reconstitution of Drs2p–Cdc50p flippase in small and giant polymer lipid hybrid vesicles is illustrated. The hybrid vesicles show adenosine 5′‐triphosphate consumption and flipping of 2‐dioleoyl‐sn‐glycero‐3‐phospho‐l‐serine lipids from the inner to the outer leaflet.

4-Hydroxymethyl-2-methoxyphenol

open access: yesActa Crystallographica Section E, 2009
The title compound, C8H10O3, is close to planar (r.m.s. deviation = 0.042 Å) apart from the hydroxyl O atom [deviation = 1.285 (1) Å] and an intramolecular O—H...O hydrogen bond occurs.

Development of polymer network of phenolic and epoxies resins mixed with linseed oil: pilot study [PDF]

open access: yes, 2010
Epoxy resin was mixed with phenolic resins in different percentages by weight. Composite 40/60 means the proportion by weight of epoxy resin is 40 percent. It was found that only composites 50/50 and 40/60 could be cured in ambient conditions. Dynamic

Selective Aerobic Oxidation of 5-(Hydroxymethyl)furfural to 5-Formyl-2-furancarboxylic Acid in Water.

open access: yesChemSusChem, 2016
A simple, cheap, and selective catalyst based on copper/cerium oxides is described for the oxidation of 5-(hydroxymethyl)furfural (5-HMF) in water. An almost quantitative conversion (99 %) with excellent (90 %) selectivity towards the formation of 5 ...

3D Printing of Conducting Polymer Hydrogels for Electrostimulation‐Assisted Tissue Engineering

open access: yesAdvanced Materials, EarlyView.
This review highlights nanosized inherently conducting polymers (ICPs) as promising ink constituents for 3D printing of conducting hydrogel (CH)‐based electrostimulation (ES) devices. ICP‐based ink formulation, 3D printing, and solidification strategies are discussed, along with the application of 3D‐printed ICP‐based CHs as ES platforms for regulating

Method of detecting and counting bacteria in body fluids [PDF]

open access: yes, 1973
A novel method is reported for determining bacterial levels in urine samples, which method depends on the quantitative determination of bacterial adenosine triphosphate (ATP) in the presence of non-bacterial ATP.

(Sp)-1-Diphenylphosphanyl-2-{(S)-[2-(diphenylphosphanyl)phenyl]hydroxymethyl}ferrocene [PDF]

open access: yes, 2008
The absolute configuration of the title compound, [Fe(C5H5)(C36H29OP2)], is Sp at the ferrocene group and S at the asymmetric C atom. Both P atoms have a trigonal-pyramidal conformation.

Unlocking the Essence of Lignin: High‐Performance Adhesives That Bond via Thiol‐Catechol Connectivities and Debond on Electrochemical Command

open access: yesAdvanced Materials, EarlyView.
A novel lignin‐inspired adhesive is presented, that combines the bonding strength of a structural adhesive with on‐demand electrochemical debonding, enabled by biomimetic thiol‐catechol connectivities. Voltage application of only 9 V facilitates electrochemical oxidation of catechols to quinones leading to guided detachment on command.
