LLM‐Assisted Design of Ultralow‐κ$\kappa$ Chalcogenides

Advanced Science, EarlyView.
An AI assisted, physics guided workflow accelerates the discovery of ultralow thermal conductivity materials by combining Bayesian optimization, evidence conditioned LLM reasoning, and automated physics‐based validation. The framework uncovers dynamically stable Ag based chalcogenides with ultralow thermal conductivity and promising thermoelectric ...

Improved electroluminescence from n-ZnO/AlN/p-GaN heterojunction light-emitting diodes

, 2010
n-ZnO/p-GaN heterojunction light-emitting diodes with and without a sandwiched AlN layer were fabricated. The electroluminescence (EL) spectrum acquired from the n-ZnO/p-GaN displays broad emission at 650 nm originating from ZnO and weak emission at 440 ...

Hepatic Lipid Stress Drives Metabolic Dysfunction‐Associated Steatohepatitis Progression through FTO O‐GlcNAcylation‐Induced m6A Demethylation of HRAS

Advanced Science, EarlyView.
Lipid stress drives O‐GlcNAcylation of the m6A demethylase FTO at Ser195, enhancing its stability and demethylase activity. This modification removes m6A from HRAS mRNA, preventing its degradation and activating PI3K/AKT signaling to promote hepatic steatosis and inflammation.

Reverse current suppression of p-GaN diode using SiOx interlayer

p-GaN diodes exhibit large reverse currents due to poor Schottky contacts between p-GaN and metal, which hinders their application in environmentally robust power systems and GaN complementary metal–oxide–semiconductor (CMOS) integration.

H4K12 Lactylation Impairs Dopaminergic Neuron Energy Metabolism via the HIF‐1α/NDUFS1 Pathway in Parkinson's Disease

Advanced Science, EarlyView.
Lactate and H4K12la are elevated in Parkinson's disease. Mechanistically, p300‐mediated H4K12la enrichment at the HIF‐1α promoter upregulates HIF‐1α, which represses Ndufs1, impairing mitochondrial respiration and energy homeostasis in DA neurons.

Improved Deformability of Co‐Free Medium Entropy Oxides by Controlled Entropy Destabilization

Advanced Science, EarlyView.
Controlled entropy destabilization activates defect‐mediated plasticity in Co‐free (CuMgNiZn)O by promoting pre‐existing Cu‐rich secondary phases that serve as defect sources. Temperature‐dependent dislocation activity evolves from limited motion at room temperature to extensive glide and stacking‐fault formation at 600 °C, enabling improved plasticity

p型GaN的掺杂研究

, 2005
采用正交实验设计方法设计p型GaN的生长,通过较少的实验,优化了影响p型GaN性质的三个生长参数:Mg流量、生长温度和Ⅴ/Ⅲ比.过量的Mg源流量、过高的生长温度、过大的Ⅴ/Ⅲ比都会降低自由空穴浓度.还研究了退火温度对p型GaN的载流子浓度和光学性质的影响.实验结果表明,700～750 ...
