Cucurbit[8]Uril Achieved Single‐Molecule Chiral Transfer to Supramolecular Circularly Polarized Luminescence

open access: yesAdvanced Science, EarlyView.
A single‐molecule cascade supramolecular system comprising L/D‐FPy, CB[8], and SC4AD serves as an efficient light‐harvesting platform. It facilitates cascade energy transfer and chiral transfer to acceptor dyes. Co‐assembly with a PVA matrix produces a multicolor solid film that exhibits enhanced luminescence dissymmetry factors (glum), enabling ...

Radical‐Based On‐Surface Transformation of Nonplanar Aromatics Into Nonbenzenoid Nanographenes

open access: yesAngewandte Chemie, EarlyView.
Formation of radicals in nonplanar hydrocarbons through thermally induced dehydrogenation leads to molecular transformation via intramolecular radical‐based cyclization and dimerization, leading to formation of nonbenzenoid nanographenes. ABSTRACT On‐surface synthesis has emerged as a powerful tool for atomically precise C─C bond formation, enabling ...

Ethical and Frugal Approaches to Animal Experimentation in Bioelectronics and Neural Engineering—An Invertebrate Renaissance?

open access: yesAdvanced Electronic Materials, EarlyView.
Invertebrates are the classic neuroscience models and should make a comeback. Invertebrate organisms can be a more ethical and cost‐effective way to move bioelectronics research forward more rapidly. ABSTRACT The accelerating development of bioelectronic neural interfaces has brought increased attention to ethical considerations surrounding in vivo ...

Light‐Induced Dispersion of Pd Single Atoms Provides Steady‐State‐Stabilized Activity for Photocatalytic H2 Generation

open access: yesAngewandte Chemie, EarlyView.
High photon flux causes (re)distionpersion of atomic Pd species on TiO2 in photocatalytic experiments, whereas Pt SAs undergo continuous agglormation. This allows light‐driven stabilization of active Pd centers for sustained H2 evolution. ABSTRACT In recent years, the use of single atoms (SAs) has become increasingly significant in photocatalysis ...

Capacitive versus Faradaic Microelectrodes for Extracellular Stimulation: A Fully Coupled FEM–Hodgkin–Huxley Study of Thresholds and Current Redistribution

open access: yesAdvanced Electronic Materials, EarlyView.
A fully coupled FEM–HH model shows that ideally capacitive microelectrodes can achieve lower charge‐density thresholds than Faradaic contacts under current‐controlled stimulation. The advantage stems from the dynamics of surface current density on capacitive interfaces, which redirects current beneath adherent neurons.

Depth‐of‐Discharge‐Dependent Chemical Evolution in Sulfurized Polyacrylonitrile Cathodes for Ether‐Based Room‐Temperature Sodium–Sulfur Batteries

open access: yesAdvanced Energy Materials, EarlyView.
Sulfurized polyacrylonitrile (SPAN) is investigated as a cathode for room‐temperature Na–S batteries in ether‐based electrolytes under controlled discharge depths. Depth‐of‐discharge‐dependent structural evolution reveals that deep discharge below 1.0 V destabilizes SPAN structure, alters polysulfide equilibria, and promotes sodium dendrite formation ...

A Machine Learning Model for Interpretable PECVD Deposition Rate Prediction

open access: yesAdvanced Intelligent Discovery, EarlyView.
This study develops six machine learning models (k‐nearest neighbors, support vector regression, decision tree, random forest, CatBoost, and backpropagation neural network) to predict SiNx deposition rates in plasma‐enhanced chemical vapor deposition using hybrid production and simulation data.

Definitions of community‐level approaches to address substance‐related harms and lessons learned: A systematic overview of reviews

open access: yesAmerican Journal of Community Psychology, EarlyView.
Abstract Community action focused on sociocultural and environmental influences to prevent alcohol and other drug (AOD) use and related harms is a global priority. Despite this recognition, understanding of effective community‐level approaches is limited.

Genetic Risk and High Burden of Depression and Suicide in the Maya‐Mestizo Population of Yucatán, México

open access: yesAmerican Journal of Medical Genetics Part B: Neuropsychiatric Genetics, EarlyView.
ABSTRACT Major depression and suicide are critical public health concerns, particularly in underrepresented populations with unique genetic and sociocultural contexts. The Maya‐mestizo population presents the highest suicide rates in the country but remains understudied in psychiatric genetics. This study evaluated the association between three genetic

Strengthening Treaty Understanding: The Role of Education in Building Durable Indigenous–State Agreements

open access: yesAustralian Journal of Social Issues, EarlyView.
ABSTRACT Education is a central mechanism for ensuring that Indigenous–State treaties are understood, supported and endure through political change. Public knowledge shapes the negotiation, acceptance, implementation and long‐term stability of agreements. In Australia, however, treaty knowledge remains fragmented.
