Adiabatic Hyperspherical Representation for the Three-body Problem in Two Dimensions [PDF]

, 2014
We explore the three-body problem in two dimensions using the adiabatic hyperspherical representation. We develop the main equations in terms of democratic hyperangular coordinates and determine several symmetry properties and boundary conditions for ...

Programmable Semi‐Interpenetrating Living Materials With Robust Stability for Versatile Bioremediation and Biotherapeutics

Advanced Science, EarlyView.
A semi‐interpenetrating engineered living material (sIHSELM), fabricated via thermosensitive hydroxybutyl chitosan and covalent protein self‐assembly, demonstrates exceptional mechanical properties and environmental stability. Shielding bacteria from harsh conditions, sIHSELM exhibits remarkable efficacy in ulcerative colitis treatment and pollutants ...

A polyphasic method for the characterization of epiphytic diatoms growing on Gelidium corneum

MethodsX
Epiphytic diatoms associated with marine macroalgae play vital ecological roles in nutrient cycling and primary production, yet their study remains limited due to the lack of standardized methodologies. This study focuses on diatom communities growing on

High‐Throughput Screening and Interpretable Machine Learning for Rational Design of Bimetallic Catalysts for Methane Activation

Advanced Science, EarlyView.
ABSTRACT Methane's efficient catalytic removal is vital for sustainable development. Bimetallic catalysts, though promising for methane activation, pose a design challenge due to their complex compositional space. This work introduces an integrated framework that combines high‐throughput density functional theory (DFT) and interpretable machine ...

Stabilizing Atomically Dispersed Au With Adjacent Pt for Spatially Precise Molecule Recognition

Advanced Science, EarlyView.
A strategy to stabilize atomically dispersed Au catalysts by introducing Pt atoms into CeO2 supports is presented. Pt incorporation prevents Au aggregation, enhances Au‐O orbital coupling, and enables precise recognition of multi‐functionalized molecules, improving catalytic performance and the structural stability of Au‐based catalysts in ...

Chiral‐Encoded Pt‐Ir Surfaces as Apparent Spin Filter for Enhanced Oxygen Reduction

Advanced Science, EarlyView.
The Chiral‐Induced Spin Selectivity (CISS) effect is employed in chiral‐encoded mesoporous Platinum‐Iridium (Pt‐Ir) electrocatalysts to enhance the oxygen reduction reaction (ORR). A break in spin symmetry leads to a substantial antagonistic difference in activity (>200%) when comparing two enantiomorphs of the same electrode.
