Advanced Functional Materials, EarlyView.We investigate size‐dependent CO selectivity on Ag nanoparticles, where optimized Ag loading achieves nearly 100% Faradaic Efficiency for CO at −100 mA·cm−2. In situ SERS and XPS reveal the crucial role of optimized loading in catalytic performance. The Ag/C catalyst further exhibits bifunctional activity, enabling efficient electrolysis of CO2 and ...

Advanced Functional Materials, EarlyView.Inspired by metal‐free carbonic anhydrases (CAs) that achieve efficient catalysis without metal cofactors, we herein report a sequence‐defined supramolecular peptoid platform that mimics metal‐free CAs and exhibits hydrolytic activity via a supramolecular assembly‐mediated proton‐transfer mechanism.

Mapping stellar streams with LSST
, 2019 Large photometric surveys like SDSS and DES have shown that the Milky Way Galaxy is littered with stellar streams; the remnants of tidally disrupted star clusters and dwarf galaxies. However these surveys were limited to either the northern sky, or only a region of the southern sky.

Advanced Functional Materials, EarlyView.Atomically dispersed Ni–S4 sites on CdS nanorods induce interfacial charge polarization, directing photogenerated electrons to H2 evolution and holes to selective ester‐bond cleavage of poly(lactic acid). Without sacrificial reagents, this charge‐coupled system produces lactate while suppressing overoxidation, achieving an H2 evolution rate of 41.74 ...

The Astrophysical JournalStellar streams are one of the most promising tracers of low-mass dark-matter subhalos. Existing frameworks for modeling stream perturbations rely on restrictive assumptions for the Milky Way potential (e.g., static, axisymmetric) or are computationally ...

Change detection in categorical evolving data streams [PDF]
, 2014 Detecting change in evolving data streams is a central issue for accurate adaptive learning. In real world applications, data streams have categorical features, and changes induced in the data distribution of these categorical features have not been ...

Epicyclic density variations in the Indus stellar stream
Monthly Notices of the Royal Astronomical SocietyABSTRACT Longitudinal density fluctuations observed in stellar streams can result from gravitational interactions with massive perturbers in the Milky Way, such as dark matter subhaloes. Analysing these density variations provides a powerful probe of properties (motion, mass, size, etc.) of the perturbing objects.

A New Tidal Stream Discovered in Gaia DR3
The Astrophysical JournalThanks to the precise astrometric measurements of proper motions by the Gaia mission, a new tidal stellar stream has been discovered in the northern hemisphere. The distribution of star count shows that the stream is approximately 80° long and 1.°70 wide.

Advanced Healthcare Materials, EarlyView.In this study, Hammer et al. highlight cyclic‐arginine surface engineering as a highly biocompatible, controllable, and concentration‐dependent regulator of intravitreal nanoparticle mobility in vivo in a translational large animal model. The cyclic arginine surface‐modification supports the development of next‐generation biomaterials for long‐acting ...
