Equilibrium Adsorption of Single Component and Binary Mixtures of Aromatic Compounds onto a Polyfunctional Hypercrosslinked Polymeric Adsorbent

Adsorption Science & Technology, 2004
A polyfunctional hypercrosslinked polymeric adsorbent, LA-8, was synthesized and characterized. It was first used to investigate the adsorption properties of 1-amino-2-naphthol-4-sulphonic acid (1,2,4-acid), including the corresponding adsorption ...

Multifunctional Design of Solid Polymer Electrolytes: Paving the Way for High‐Performance All‐Solid‐State Batteries

Carbon Energy, EarlyView.
This review provides a comprehensive and systematic overview of the multifunctional design strategies for solid polymer electrolytes (SPEs), a pivotal component for enabling high‐performance all‐solid‐state batteries (ASSBs). It begins with a detailed classification of SPE systems and elaborates on their respective molecular design principles. The work

Separate hydrolysis and fermentation of softwood bark pretreated with 2-naphthol by steam explosion

Biotechnology for Biofuels and Bioproducts
Background 2-Naphthol, a carbocation scavenger, is known to mitigate lignin condensation during the acidic processing of lignocellulosic biomass, which may benefit downstream processing of the resulting materials. Consequently, various raw materials have

Flipping the Card With Enantiodivergent Organocatalysis

Chemistry – A European Journal, EarlyView.
This minireview elaborates on recent organocatalytic strategies for achieving enantiodivergence—the ability to access both product enantiomers using a single chiral catalyst. It highlights how achiral stimuli, such as solvent polarity and chemical additives, along with minimal catalyst modifications, trigger stereochemical inversions in reactions ...

Nitrooxylation in Organic Synthesis: From Classical Nitrate Ester Formation to Modern Catalytic Strategies

Chemistry – A European Journal, EarlyView.
Nitrooxylation—the installation of nitrate esters (–ONO2) has evolved from classical mixed‐acid protocols to catalytic and mechano‐, flow‐, photo‐, and electrochemical strategies. This review delineates ionic and radical manifolds for C–ONO2 bond formation, emphasizing mechanistic control, selected substrate scope, and selectivity.

Coordination Chemistry of Boron Subphthalocyanine With BINOL Derivatives: Unexpected Oxidation to Oxa[4]Helicene and Properties of the Resulting Axially Coordinated Complexes Containing Oxa[4]Helicene and/or BINOL Derivatives

Chemistry – A European Journal, EarlyView.
Treatment of BINOL with a boron subphthalocyanine derivative resulted in the formation of a complex coordinated to an oxa[4]helicene derivative, which is generated via a ring‐closure reaction of BINOL. In contrast, treatment of the monomethyl ether of 1,1′‐bi‐2‐naphthol (BINOL) afforded the expected axially coordinated complex.
