Synthesis of dihydropyridine and piperidine derivatives via an unexpected reaction of pyridine with acetyl chloride [PDF]

open access: yes, 2013
Acetyl chloride reacts with pyridine to give a mixture of N-acetyl-1,4- and 1,2-dihydropyridyl acetic acid (1a,b) after water quenching. The reactioninvolves the formation of a zwitterionic ketene enolate intermediate which results from deprotonation of

Differential Compartmentalization of Enzymatic Reactions for Lactate Signaling Across Protocells

open access: yesAdvanced Functional Materials, EarlyView.
Two populations of protocells consisting of giant unilamellar vesicles containing active species and distinct artificial organelles are competent of collective behavior by mimicking production, intercellular communication, and detection of the bioinspired signal molecule lactate. Enzymatic cascade reactions within artificial organelles demonstrate that

A Sustainable Biotechnology Approach for Mineral Separation

open access: yesAdvanced Functional Materials, EarlyView.
Silver‑binding peptides are first identified through phage‐display screening, and then engineered into multifunctional and responsive peptides or proteins. These tailored biomolecules can selectively capture and aggregate silver particles or ions from complex mixtures, enabling rapid and efficient silver separation and recovery.

Rationally Designed Carbon Nanomaterials for Electrically Driven Solid‐State Hydrogen Storage

open access: yesAdvanced Functional Materials, EarlyView.
A bottom‐up design principle integrating atomic‐level and nanoscale structural engineering is developed to guide the rational design of electrically tunable, solid‐state hydrogen storage materials that enable non‐dissociative chemisorption under applied electric fields.

Defect‐Free Block Copolymer‐Based Distributed Bragg Reflector for Optimized Light Harvesting in BiVO4 Photoanodes

open access: yesAdvanced Functional Materials, EarlyView.
A solution‐processed distributed Bragg reflector (DBR) film, integrated via block copolymer (BCP) self‐assembly, enhances photon recycling in BiVO4 photoanodes for improved photoelectrochemical (PEC) performance. By tuning lamellar structures using lactic acid and cross‐linking density, the DBR film optimally shifts working wavelengths, boosting ...
