Chloroperoxidase-catalyzed aminoalcohol oxidation : substrate specificity and novel strategy for the synthesis of N-Cbz-3-aminopropanal [PDF]

open access: yes, 2016
The ability of chloroperoxidase (CPO) to catalyze amino alcohol oxidations was investigated. The oxidations of compounds with different configurations with respect to the amine position towards hydroxyl - using H₂O₂ and tert-butyl hydroperoxide (t-BuOOH)

Artifact‐Minimizing Ultrathin Transparent Electrodes Fabricated via iCVD for In Vivo Optogenetic Stimulation and Neural Signal Monitoring of Primary Visual Cortex

open access: yesAdvanced Functional Materials, EarlyView.
We present ultrathin flexible transparent electrodes through iCVD‐enabled molecular control of 10 nm gold films on poly(dimethylaminomethylstyrene). In vivo validation demonstrated photoelectric artifact reduction vs. opaque electrodes and preservation of natural neural dynamics.

On the Stabilizing Action of Protein Denaturants: Acetonitrile Effect on Stability of Lysozyme in Aqueous Solutions [PDF]

open access: yes, 2000
Stability of hen lysozyme in the presence of acetonitrile (MeCN) at different pH values of the medium was studied by scanning microcalorimetry with a special emphasis on determination of reliable values of the denaturational heat capacity change.

Shape‐Controlled Guanine Self‐Assemblies for Stable and Fast‐Ion Solid–Electrolyte Interphases in Sustainable Li Metal Batteries

open access: yesAdvanced Functional Materials, EarlyView.
The shape of guanine self‐assemblies is tuned by introducing alkyl (G8), fluoroalkyl (G8f), and oligoether (G8g) side chains into the G moiety. The scanning tunneling microscopy results and calculations show that the presence and type of the side chain strongly affect the G self‐assembly network.

Photo‐Promoted Nitrogen‐Centered Radical Mediated Intermolecular Aminative Carbonylation of Tertiary Allyl Alcohols to Access β‐Amino Ketones through (Hetero)Aryl Migration

open access: yesChemistryEurope
Carbon monoxide, as a crucial C1 synthon, has been widely used in the difunctionalization of alkenes. Additionally, nitrogen‐centered radicals (NCRs) are also effective intermediates for constructing C−N bonds.

Carbohydrate-Based Chiral Ligands for the Enantioselective Addition of Diethylzinc to Aldehydes

open access: yesPharmaceuticals
Background: Carbohydrate-derived chiral ligands are promising tools in asymmetric catalysis due to their structural diversity, chirality, and availability. However, ligands based on galactose or sorbose have been scarcely explored in the enantioselective

Enantioselective conjugate addition of ketones to β-nitrostyrenes catalyzed by 1,2-amino alcohol-derived prolinamides [PDF]

open access: yes, 2006
Various l-prolinamides 14, prepared from l-proline and chiral β-amino alcohols, are active bifunctional catalysts for the direct nitro-Michael addition of ketones to β-nitrostyrenes.

Magnetothermal‐Triggered Response and Self‐Healing of Recyclable and Reprocessable Nanocomposites for Actuation Systems

open access: yesAdvanced Functional Materials, EarlyView.
Developing recyclable materials for magnetic robotics that combine rapid response and self‐healing properties is challenging. Hence, this study focuses on the integration of magnetothermal nanoparticles into a dynamic sorbitol‐based vitrimer, a recyclable composite capable of remote actuation and self‐healing by magnetic heating.
