Lattice Distortion‐Driven Metal Exsolution in Perovskite Oxides

Advanced Science, EarlyView.
This study elucidates the mechanism of lattice distortion‐driven exsolution through a combination of computational simulations and experimental approaches. Lattice distortion facilitates the formation of oxygen vacancies and subsequent metal segregation, thereby enhancing the exsolution behavior.

Interfacial Proton‐Relay Microenvironment Enables Self‐Driven Singlet Oxygen Generation under Neutral Conditions

Advanced Science, EarlyView.
An interfacial proton‐relay microenvironment at MoS2‐CuCl heterostructures enables selective O2 activation to 1O2 under neutral conditions. Electron‐deficient sulfur sites mediate proton transfer to Cu‐bound O2, accelerating *OOH hydrogenation while suppressing O─O bond cleavage, achieving stable, efficient pollutant removal.

Unlocking Strength‐Toughness Dilemma in High‐Entropy Borides by Intragranular Microstructural Reconstruction

Advanced Science, EarlyView.
An extreme non‐equilibrium process combining heavy direct current sintering and TiSi2 addition is used to construct intragranular energy dissipation units within high‐entropy boride ceramics to overcome the strength‐toughness trade‐off. The resulting ceramic demonstrates attractive mechanical properties with a flexural strength of 887 MPa and a ...

The Gasification and Pyrolysis of Biomass Using a Plasma System

Energies
This research paper analyzes the use of plasma technology to process biomass in the form of dried, mixed animal manure (dung containing 30% moisture). The irrational use of manure as well as huge quantities of it can negatively impact the environment. In

Study of Luminescence in Noble Gases and Binary Kr-Xe Mixture Excited by the Products of 6Li(n,α)T Nuclear Reaction

Eurasian Chemico-Technological Journal, 2019
At the present time the direct nuclear energy conversion into optical radiation is realized in gas media in which filling of energy levels takes place in the low-temperature plasma (nuclear-excited plasma) induced by ionizing radiation.

Graphene (0002)/Diamond (111) Heterojunction with High Piezoresistive Response

Advanced Science, EarlyView.
Graphene/diamond heterostructures show promise as silicon alternatives for semiconductors, but high‐quality integration is challenging. Thermal electron irradiation enables covalent bonding; lonsdaleite acts as an intermediate. The heterostructure exhibits a high piezoresistive response (gauge factor −1149) associated with electron‐rich layers and ...

Ultra‐Radiostable Covalent Conformationally Interlocked Networks Enabling a Universal Radiometal‐Labeling Platform for Cancer Radioembolization

Advanced Science, EarlyView.
Conjugated poly(imide dioxime)‐based microspheres establish a radiometal coordination‐driven conformational interlocked network with ultra‐high radiostability. This platform enables low‐temperature, multi‐radionuclide labeling for SPECT/PET/MRI imaging and radionuclide therapy. Mechanistic insights from EXAFS and DFT reveal enhanced stability, while in
