Lithiophilic Current Collector Without Interfacial Penalty in Zero‐Excess Lithium Metal Batteries

open access: yesAdvanced Science, EarlyView.
Bilayer lithiophilic coatings are introduced to overcome the structural fragility of conventional single‐layer current collectors in zero‐excess Li‐metal batteries (ZE‐LMBs). By integrating density functional theory with electrochemical analyses, the Ag‐outer/Pt‐inner configuration enables uniform Li deposition, robust SEI formation, and persistent ...

Capital Account Liberalization: Allocative Efficiency or Animal Spirits? [PDF]

open access: yes
In the year that capital-poor countries open their stock markets to foreign investors, the growth rate of their typical firm's capital stock exceeds its pre-liberalization mean by 4.1 percentage points.

A Soft, Flexible Implant for Wireless Photothermal–Pyroelectric Neurostimulation

open access: yesAdvanced Science, EarlyView.
A replication strategy is used to enlarge the exposed surface area of barium titanate within flexible films with embedded carbon nanotubes, enabling efficient photothermal‐pyroelectric stimulation. Polar crystalline nanosheets show superior performance in guiding neural progenitor cells toward neuronal differentiation.

PROFIT EFFICIENCY AMONG BANGLADESHI RICE FARMERS [PDF]

open access: yes
Production inefficiency is usually analysed by its two components - technical efficiency and allocative efficiency. In this study we provide a direct measure of production efficiency of the Bangladeshi rice farmers using a stochastic profit frontier and ...

Inhibition of SIRT7 Overcomes Radioresistance in Pancreatic Neuroendocrine Tumors by Reactivating MEN1 Expression

open access: yesAdvanced Science, EarlyView.
Pancreatic neuroendocrine tumors frequently silence MEN1 through epigenetic mechanisms. Here, SIRT7 recruits DNMT1 to the MEN1 promoter, drives hypermethylation, and enhances DNA repair. Inhibiting SIRT7 restores MEN1, reduces MRN complex abundance, impairs double‐strand break repair, and sensitizes PanNET models to radiation, supporting SIRT7 as a ...

SOME TESTS OF THE ECONOMIC THEORY OF COOPERATIVES: METHODOLOGY AND APPLICATION TO COTTON GINNING [PDF]

open access: yes
Little progress has been made in testing the often conflicting hypotheses generated from theoretical research on cooperatives. This paper addresses the deficiency by describing and applying (to California cotton ginning cooperatives) a methodology to ...

Global Nitrogen Deposition Promotes Carbon Sink Formation in Terrestrial Ecosystems

open access: yesAdvanced Science, EarlyView.
Nitrogen deposition alleviates ecosystem N limitation and enhances carbon sinks. Using 829 observations, we show 36% of deposited N is retained globally (39.15 Tg N yr−1), with distinct NHx and NOy contributions. This retention drives a terrestrial C sink of 0.88 Pg C yr−1 (25.48%), highlighting the importance of pool‐specific C:N stoichiometry ...
