Spiral packing and chiral selectivity in model membranes probed by phase-resolved sum-frequency generation microscopy

open access: yesNature Communications
Since the lipid raft model was developed at the end of the last century, it became clear that the specific molecular arrangements of phospholipid assemblies within a membrane have profound implications in a vast range of physiological functions.

Dynamic Etching‐Induced Cl‐Terminated Ti3C2Clx/Ti3ZnC2 Heterostructure for Ammonia Electrosynthesis and Zinc‐Nitrogen Batteries

open access: yesAdvanced Science, EarlyView.
A stable Ti3C2Clx/Ti3ZnC2 heterostructure, fabricated by dynamic etching, exhibits outstanding electrocatalytic NRR activity (NH3 yield: 20.1 µg h−1 mg−1, FE: 38.1%) in alkaline media. The corresponding Zn‐N2 battery achieves a peak power density of 36.5 µW cm−2 and an NH3 yield of 13.1 µg h−1 mg−1, providing an advanced strategy for NH3 and ...

Integrating Machine Learning With Constant‐Potential Simulation to Unravel Charge‐Transfer Mechanisms in Electrochemical Nitrogen Fixation

open access: yesAdvanced Science, EarlyView.
Integrating interpretable machine learning with the fixed‐potential method reveals a novel mechanism: the catalytic activity of the electrochemical nitrogen reduction reaction is governed by partial charge transfer, induced by variations in the intermediate potential of zero charge under constant potential.

Haber

open access: yes, 2021
Felç hastası olan babasına bakması için kocasıyla anlaşan Ayşe, İlknur adında birbakıcı ile anlaşır. İlknur?un amacı aslında felçli hastaya bakmak yerine kendi haberiniyaratmak için öldürmektir. Bu onun ilk cinayeti değildir.

New LHC Benchmarks for the CP-conserving Two-Higgs-Doublet Model

open access: yes, 2015
We introduce a strategy to study the parameter space of the general, CP-conserving, two-Higgs-doublet Model (2HDM) with a softly broken Z_2-symmetry by means of a new "hybrid" basis.

Tailored Catalytic Microenvironments Enable Efficient Electrochemical Ammonia Production

open access: yesAdvanced Science, EarlyView.
This study shows that Co2+ substitution in inverse spinel FeFeCoO4 constructs an integrated catalytic microenvironment for efficient nitrate‐to‐ammonia reduction. Jahn–Teller distortion activates Fe sites for *H generation, while hard–soft acid–base regulated dual‐metal sites optimize proton‐coupled electron transfer and intermediate adsorption ...

Bioinspired Interfacial Hydration Engineering via Metal–Organic Frameworks for Efficient Nitrate‐To‐Ammonia Conversion in Neutral Media

open access: yesAdvanced Science, EarlyView.
Inspired by Nitrite reductase, a metal–organic framework overlayer is introduced to regulate the interfacial hydration microenvironment on Cu electrodes, enriching hydrated K+ species that act as efficient proton donors. This strategy enables nitrate‐to‐ammonia conversion with near‐unity selectivity at industrial‐level current densities in neutral ...
