Facet‐Controlled Growth of Molybdenum Phosphide Single Crystals for Efficient Hydrogen Peroxide Synthesis

open access: yesAdvanced Materials, EarlyView.
Facet‐controlled growth of molybdenum phosphide single crystals via liquid‐metal‐assisted chemical vapor deposition, demonstrating MoP nanoplate and pillar morphologies formed at different temperatures for efficient hydrogen peroxide synthesis. Abstract Transition metal phosphides (TMPs) stand out for their excellent catalytic activity, driven by metal‒

Selective Electrosynthesis of Methanol from CO2 Over Cu/Cu2P2O7 Via the Formate Pathway

open access: yesAdvanced Materials, EarlyView.
A Cu/Cu2P2O7‐based hybrid catalyst delivers over 50% Faradaic efficiency and >100 mA cm−2 partial current density for methanol electrosynthesis from CO2. The synergy between Cu (111) facets and Cu2P2O7 promotes HCOOH‐mediated pathways, offering a scalable route for sustainable liquid fuel production. Abstract The electrochemical CO2 reduction reaction (

Notes on Nash modification [PDF]

open access: yesarXiv
The Nash blowing-up (or modification) of an algebraic variety $X$ is a canonical process that produces a proper, birational morphism $\pi : X' \to X$ of varieties. It is expected that the singularities of $X'$ will be better than those of $X$. In the mid-1970's, it was proved that in characteristic zero, ${\pi}$ is an isomorphism if and only if $X$ is ...

Mussel‐Inspired Molecular Strategies for Fabricating Functional Materials With Underwater Adhesion and Self‐Healing Properties

open access: yesAdvanced Materials, EarlyView.
This review systematically examines the nanomechanical mechanisms of mussel‐inspired molecular interactions, primarily investigated by direct force measurement techniques such as surface forces apparatus and atomic force microscopy. The macroscopic adhesive and self‐healing performances of mussel‐inspired functional materials, including coacervates ...
