Chemically Driven Nano‐Elastic Heterogeneities Control Fragility in Volcanic Melts

Advanced Science, EarlyView.
The study elucidates how nanoscale structural heterogeneity governs the mechanical behavior of volcanic glasses across compositions from basalt to rhyolite. Using a physicochemical framework, correlation length (ξ) and microscopic free volume (Vc) are derived from vibrational and physical properties, revealing systematic trends with silica content that

A Closed‐Loop‐Capable Neural Interface Platform for Deep Brain Modulation via Integrated Non‐Viral Gene Delivery, NIR Optogenetics, and Electrophysiological Recording

Advanced Science, EarlyView.
A multifunctional, 3D porous neural interface combines non‐viral gene delivery and NIR optogenetics to enable minimally invasive, closed‐loop modulation of deep‐brain circuits. Abstract Closed‐loop neuromodulation requires precise, stable, and cell‐specific control of neural circuits with minimal invasiveness.

Defect‐Cascades‐Induced Photodegradation in InP/ZnSe/ZnS Quantum Dots

Advanced Science, EarlyView.
Surface sulfur vacancies in InP/ZnSe/ZnS quantum dots trigger vacancy cascades under blue light, propagating toward the ZnSe interface. In situ ESR (g = 2.004, 2.012) and DFT reveal a defect‐driven shift from type‐I to type‐II band alignment, reducing radiative recombination and EQE.

Low-Cost Real-Time Gas Monitoring Using a Laser Plasma Induced by a Third Harmonic Q-Switched Nd-YAG Laser [PDF]

ITB Journal of Engineering Science, 2005
A gas plasma induced by a third harmonic Nd-YAG laser with relatively low pulsed energy (about 10 mJ) has favorable characteristics for gas analysis due to its low background characteristics, nevertheless a high power fundamental Nd-YAG laser (100-200 mJ)

Laser Cooling of Dense Rubidium-Noble Gas Mixtures via Collisional Redistribution of Radiation

, 2012
We describe experiments on the laser cooling of both helium-rubidium and argon-rubidium gas mixtures by collisional redistribution of radiation. Frequent alkali-noble gas collisions in the ultradense gas, with typically 200\,bar of noble buffer gas ...

Integrin β3 Orchestrates Hepatic Steatosis via a Novel CD36‐Dependent Lipid Uptake Complex

Advanced Science, EarlyView.
In MASH, ITGB3 recruits LYN and drives its ubiquitin‐proteasomal degradation via phosphorylation. This relieves DHHC5 inhibition, enabling ITGB3/DHHC5/CD36 complex assembly to enhance CD36 palmitoylation and fatty acid uptake, thereby exacerbating disease. Targeting ITGB3 blocks this pathogenic axis and ameliorates MASH.

The Experimental and Modeling Study on the Thermodynamic Equilibrium Hydrate Formation Pressure of Helium-Rich Natural Gas in the Presence of Tetrahydrofuran

Molecules
Hydrate-based gas separation (HBGS) has good potential in the separation of helium from helium-rich natural gas. HBGS should be carried out under a pressure higher than the thermodynamic equilibrium hydrate formation pressure (Peq) to ensure the ...
