Salt Water Drops Slide Faster: Ionic Modulation of Drop Friction

Advanced Science, EarlyView.
Salt ions markedly accelerate water drops on conductive substrates coated with nanometer‐thin hydrophobic layers. Across diverse electrolytes and surfaces, higher ion concentration consistently lowers kinetic friction by reducing contact angle hysteresis.

Ultrafast Electron Transfer Coupled with a Proton Relay in an Anisotropic Dual S‐Scheme Heterojunction for Overcoming Kinetics Mismatch in H2O2 Photosynthesis

Advanced Science, EarlyView.
An anisotropic dual S‐scheme heterojunction (C3N4/SubPc‐1/C3N5) is constructed to overcome the electron–proton kinetics mismatch in photocatalytic H2O2 production. The imide bridge serves as a dual channel for ultrafast electron transfer and proton relay, synergistically enabling efficient dual‐pathway oxygen reduction and achieving a high H2O2 ...

In‐Wheel Piezoelectric DC Power Generator With Zero Resistive Torque

Advanced Science, EarlyView.
In this paper, we present a wheel‐shaped direct‐current piezoelectric generator (DC‐PG) that fundamentally overcomes these constraints by producing phase‐stable DC electricity directly from rolling motion. By embedding this system into suitcase wheels, we demonstrated a fully integrated real‐time location tracking system powered solely by mechanical ...

A Dual‐Piezoelectric Metal–Organic Cage/COF Z‐Scheme Heterojunction for Solar‐Mechanical Water Splitting

Advanced Science, EarlyView.
A dual‐piezoelectric Z‐scheme heterojunction is constructed by integrating a piezoelectric metal–organic cage (MOC‐FA3) with a β‐ketoenamine‐linked covalent organic framework (S‐COF). This design enables efficient solar‐mechanical energy conversion, achieving remarkable piezo‐photocatalytic pure water splitting for simultaneous H2 and H2O2 production ...

The Kr85 s-process Branching and the Mass of Carbon Stars

, 2001
We present new spectroscopic observations for a sample of C(N)-type red giants. These objects belong to the class of Asymptotic Giant Branch stars, experiencing thermal instabilities in the He-burning shell (thermal pulses).

Apoptosis induced by t10,c12-conjugated linoleic acid is mediated by an atypical endoplasmic reticulum stress response*

Journal of Lipid Research, 2008
Conjugated linoleic acid (CLA) inhibits rat mammary carcinogenesis, in part by inducing apoptosis of preneoplastic and neoplastic mammary epithelial cells. The current study focused on the mechanism by which apoptosis is induced.
