Co‐activation of Selective Nicotinic Acetylcholine Receptor Subtypes Is Required for Neuroprotection against Alzheimer's Disease

open access: yesAdvanced Science, EarlyView.
ABSTRACT Beta‐amyloid peptide (Aβ)‐induced suppression of hippocampal GABAergic interneuron activity drives hyperexcitability, amyloid pathology, and cognitive impairment in Alzheimer's disease (AD), suggesting that enhancing hippocampal inhibition may be protective.

Oxygen‐Tolerant, Controlled Synthesis of Degradable and Water‐Soluble Poly(Vinyl Amide)s via Radical Ring‐Opening Copolymerization of Cyclic Dithiothreitol

open access: yesAngewandte Chemie, EarlyView.
Oxygen‐tolerant photoinduced electron/energy transfer reversible addition–fragmentation chain transfer (PET‐RAFT) polymerization enables the controlled radical ring‐opening (rROP) copolymerization of cyclic dithiothreitol (cDTT) with less‐activated vinyl monomers, affording degradable polymers with predictable molecular weights, low dispersities, and ...

Green approach for tracking the photofate of ciprofloxacin and levofloxacin in different matrices adopting synchronous fluorescence spectroscopy: a kinetic study

open access: yesRoyal Society Open Science, 2023
First derivative synchronous fluorescence spectroscopy (FDSFS) was applied to detect and quantify either ciprofloxacin (CIP) or levofloxacin (LEV) simultaneously with their photodegradation products, where the photolytic pathway for each analyte was ...

CO-Photolysis-Induced H‑Atom Transfer from MnIO–H Bonds

open access: yes, 2019
The formation of TEMPOH from a mixture of [Mn­(CO)3(μ3-OH)]4 (1) and (2,2,6,6-tetramethylpiperidin-1-yl)­oxyl (TEMPO) is shown to occur through a light-initiated CO photolysis from 1 (illumination at 300–375 nm). One hypothesis is that the loss of carbon

Advancing Energy Materials by In Situ Atomic Scale Methods

open access: yesAdvanced Energy Materials, Volume 15, Issue 11, March 18, 2025.
Progress in in situ atomic scale methods leads to an improved understanding of new and advanced energy materials, where a local understanding of complex, inhomogeneous systems or interfaces down to the atomic scale and quantum level is required. Topics from photovoltaics, dissipation losses, phase transitions, and chemical energy conversion are ...

Enhancing Stability of Layered Double Perovskites With a Naphthalene Diimide Spacer Toward Photoelectrochemical Application

open access: yesAngewandte Chemie, EarlyView.
A bulky, hydrophobic naphthalene diimide dication spacer (NDI‐dH2+) endows the lead‐free layered double perovskite (NDI‐dH)2AgBiI8 with threefold‐higher in‐plane carrier mobility, an order‐of‐magnitude lower trap density, and exceptional water tolerance compared to aliphatic and benzene‐based analogues, enabling the first sustained photoelectrochemical

Light‐Induced Phase Segregation in Mixed‐Halide Perovskites: Reconciling Mechanistic and Thermodynamic Models

open access: yesAdvanced Energy Materials, EarlyView.
Light‐induced halide segregation limits the stability of mixed‐halide perovskites. This perspective shows how different mechanistic models can be viewed within a common free‐energy framework. It highlights the need to separate kinetic and thermodynamic aspects, the need for bulk‐sensitive measurements, and the need for controlled conditions to identify
