Energy‐Resolved Femtosecond Dynamics of Plasmon‐Induced Hole Injection at Au/GaN Heterointerfaces

Advanced Science, EarlyView.
We reveal the spectral signature of ultrafast nonthermal hot‐hole transfer at plasmonic heterointerfaces, which reshapes hot‐carrier relaxation dynamics and significantly enhances hydrogen evolution, providing a mechanistic basis for optimizing hot‐carrier utilization in photocatalysis.

Quark spin in the proton

, 2010
The proton spin puzzle has challenged our understanding of QCD for the last 20 years. We survey new developments in theory and experiment. The proton spin puzzle seems to be telling us about the interplay of valence quarks with chiral dynamics and the ...

Superatom Distortion Induces Triferroicity and Spin Splitting in Two‐Dimensional Antiferromagnets

Advanced Science, EarlyView.
The incorporation of superatoms into a 2D square lattice induces symmetry breaking, thereby enabling concurrent coupling among magnetism, ferroelectricity, and ferroelasticity. This strategy achieves triferroic behavior—characterized by spin‐split antiferromagnetic ground states—and offers a viable pathway toward energy‐efficient spintronic devices ...

Differences in gas-bearing properties of deep and shallow coal reservoirs and their implications for coalbed methane production in the western section of the southern margin of the Junggar Basin, Xinjiang

Meitian dizhi yu kantan
BackgroundIn recent years, breakthroughs have been constantly achieved in the production of coalbed methane (CBM) at burial depths exceeding 2 000 m in China, with the gas-bearing properties of coal reservoirs identified as a primary geological parameter

Insights and challenges of applying the $GW$ method to transition metal oxides

, 2014
The ab initio $GW$ method is considered as the most accurate approach for calculating the band gaps of semiconductors and insulators. Yet its application to transition metal oxides (TMOs) has been hindered by the failure of traditional approximations ...

Diffusion‐Driven Targeted Passivation of Selenium Vacancies via an I‐Doped CdS Buffer Layer for Efficient Sb2Se3 Solar Cells

Advanced Science, EarlyView.
Iodine incorporation into the CdS buffer layer induces spontaneous anion diffusion and selectively passivates selenium vacancies in Sb2Se3 absorbers. The formation of low‐energy, charge‐neutral ISe defects effectively suppresses non‐radiative recombination, resulting in a substantially enhanced open‐circuit voltage and boosting the device efficiency to

Delayed Halide‐Rich Molecular Passivation of CsPbCl3 Perovskite Nanocrystals Enables Bright Violet Light‐Emitting Diodes

Angewandte Chemie, EarlyView.
POCl3 enables delayed dual passivation in CsPbCl3 nanocrystals by slowly releasing Cl‐containing and phosphonic species that heal halide vacancies and Pb‐related defects over time. This self‐healing boosts PLQY by >40‐fold, preserves efficient violet emission for over 2 months in air, and yields a record 409 cd m−2 luminance for CsPbCl3 violet LEDs ...

Manipulating Atomic Disorder and Mesoscale Architectures for High‐Efficiency Thermoelectric Modules

Advanced Science, EarlyView.
The in situ reaction of PbTiO3 precursor reacts in situ with the Bi0.5Sb1.5Te3 matrix, effectively enlarging the energy barrier for minority carrier excitation and suppressing bipolar diffusion, and predominantly scattering mid‐to‐low frequency phonons. Ultimately, a single thermoelectric module was fabricated to achieve a competitive efficiency of ∼7%
