The sdA problem - II. Photometric and Spectroscopic Follow-up [PDF]

, 2018
Subdwarf A star (sdA) is a spectral classification given to objects showing H-rich spectra and sub-main sequence surface gravities, but effective temperature lower than the zero-age horizontal branch. Their evolutionary origin is an enigma. In this work,

Unraveling Quantitative Sensing Mechanism and Predictive Molecular Metrics for High‐Performance OFET Amine Sensors

Advanced Functional Materials, EarlyView.
This study introduces a novel chloro boron subphthalocyanine/polymer blend OFET sensor achieving 0.005 ppb limit of detection for ammonia at room temperature and high selectivity against similar amines. An original theoretical framework is proposed to describe the sensing mechanism, relating analyte molecular volume and Lewis basicity to sensor ...

Exploring the physics of a high-performance H-mode scenario with small ELMs at low collisionality in JET with Be/W wall

Nuclear Fusion
A new H-mode regime at low density and low edge safety factor ( q _95 = 3.2, with $I_\mathrm{p}$ = 3 MA) that combines high energy confinement, stationary conditions for density and radiation and small Edge Localized Modes (ELMs) have been found in JET ...

Deciphering Small Molecule Diffusion Parameters Across Light Responsive Polymersome Membranes

Advanced Functional Materials, EarlyView.
Light‐responsive polymersomes bearing donor–acceptor Stenhouse adducts (DASAs) enable programmable control over small‐molecule transport across synthetic membranes. By systematically varying DASA density, an optimal functionalization regime is identified that maximizes light‐gated permeability.

Nanolayer‐Encapsulated Stretchable Liquid‐Metal Sheets for Thermal Management

Advanced Functional Materials, EarlyView.
A stretchable liquid metal sheet with both high thermal conductivity and mechanical flexibility is developed. Its trilayer structure, comprising copper‐particle‐dispersed gallium liquid metal encapsulated by styrene‐butadiene‐styrene nanosheets, shows 40.4 W m−1 K−1 conductivity, elongation exceeding 200%, and retention of 96% of its initial ...

An Engineered Living Material With Pro‐Angiogenic Activity Inducible by Near‐Infrared Light

Advanced Functional Materials, EarlyView.
NIR‐responsive engineered living materials (ELMs) for controlled angiogenesis: Near‐infrared (800 nm) light activates engineered probiotic bacteria within alginate‐based living materials to secrete a blood vessel‐regenerating protein. The released protein promotes pro‐angiogenic effects in endothelial networks and chick chorioallantoic membranes.
