Expanding Transparent Covalently Attached Liquid‐Like Surfaces for Icephobic Coatings with Broad Substrate Compatibility

Advanced Materials Interfaces, EarlyView.
This study introduces an approach for creating liquid‐like slippery surfaces (LLS) on various substrates. An epoxy‐silicon (EpSi) coating is applied, plasma‐activated, and immersed in an organosilane solution, forming siloxane chains. The resulting LLS exhibits ultra‐low ice adhesion, high transparency, self‐cleaning, and anti‐staining properties ...

The Chemo-Dynamical Evolution Of The Milky Way Disc

, 2016
The kinematic properties of the stellar subpopulations in the Milky Way disc are linked to their radial and vertical scale lengths. On the other hand, element abundances and abundance ratios are a signature of the evolution history of the stellar components.

The Chemo-Dynamical History of the Milky Way as Revealed by SDSS/SEGUE [PDF]

Proceedings of the International Astronomical Union, 2009
AbstractAlthough originally conceived as primarily an extragalactic survey, the Sloan Digital Sky Survey (SDSS-I), and its extensions SDSS-II and SDSS-III, continue to have a major impact on our understanding of the formation and evolution of our host galaxy, the Milky Way.

Anti‐Counterfeiting Tags with Camouflaged QR Codes on Nanocavities, Using Polymer‐Dispersed Liquid Crystals

Advanced Materials Technologies, EarlyView.
A QR code, printed through a commercial printer on a thin plastic foil, pre‐coated with a nanocavity is proposed as an anti‐counterfeiting label. Nanocavity imparts distinctive optical properties in terms of light reflection and transmission. A thin layer of polymer‐dispersed liquid crystals (PDLC) is used to camouflage the QR code, that become ...

Mimicking Symmetry‐Breaking Einstein Ring by Optical Lens

Advanced Photonics Research, EarlyView.
This article uses an optical lens to emulate the gravitational lensing effect and observe the Einstein ring (ER) patterns. The symmetry‐breaking ER, i.e., Einstein cross, is observed utilizing a rotation‐symmetry‐breaking hemi‐ellipsoid lens. Deformed Einstein cross patterns induced by noncollinearly alignment of the light source–lens–observer are ...

An Eccentricity-Mass Relation for Galaxies from Tidally Disrupting Satellites [PDF]

arXiv, 2014
We infer the past orbit of the Sagittarius (Sgr) dwarf galaxy in the Milky Way halo by integrating backwards from its observed position and proper motions, including the effects of dynamical friction. Given measured proper motions, we show that there is a relation between the eccentricity ($e$) of Sgr's orbit and the mass of the Milky Way ($M_{T}$) in ...

Virulent Factor‐Targeted Point‐of‐Care Biosensor for Detection of Staphylococcus Aureus Infections

Advanced Sensor Research, EarlyView.
In this work, the use of aureolysin as a biomarker of Staphylococcus Aureus infection in periprosthetic joint infection (PJI) is presented for the first time. Through the immobilization of an anti‐aureolysin antibody on gold nanospike‐modified screen‐printed electrodes, it is successfully detected aureolysin in both buffer solution and bacterial ...

Dual Charge Transfer Mechanisms in Intimately Bonded S‐scheme Heterojunction Photocatalyst with Expeditious Activity toward Environmental Remediation

Advanced Sustainable Systems, EarlyView.
A novel MBOdCN S‐scheme heterojunction photocatalyst is fabricated using pristine Mg‐Bi2O3 and grayish g‐C3N4, where dynamic dual charge migration paths occur to accelerate exciton dissociation. This composite catalyst realizes high degradation efficiency of up to 99.56% of oxytetracycline (OTC) removal under optimized conditions. The material exhibits

Insights into the Dynamics and Binding Mechanisms of the Alkhumra Virus NS2B/NS3 Protease: A Molecular Dynamics Study

Advanced Theory and Simulations, EarlyView.
The ΔRMSF$\Delta {\rm RMSF}$ analysis reveals significant flexibility differences between free NS3 and the NS2B/NS3 complex, with notable deviations in specific regions. Key residues driving NS2B binding are identified, and the protonation state of catalytic serine affects oxyanion hole formation.

The Age Distribution of Stellar Orbit Space Clumps

The Astrophysical Journal
The orbit distribution of young stars in the Galactic disk is highly structured, from well-defined clusters to streams of stars that may be widely dispersed across the sky, but are compact in orbital action-angle space.
