Atomically precise metal cluster enzymes for pathological tissue regeneration

BMEMat, EarlyView.
Schematic illustration of atomically precise metal cluster enzymes (MCEs) for pathological tissue regeneration. Atomically precise MCEs can modulate biological processes, such as attenuation of inflammatory responses, eradication of bacterial pathogens, regulation of angiogenesis, and promotion of cell development.

Harnessing ferroptosis from multilayer defense networks to nanoplatforms for specific cancer therapy

BMEMat, EarlyView.
Nanomaterials target metabolically‐regulated ferroptosis for cancer therapy. Iron‐based or alternative nanoplatforms integrate ferroptosis with chemotherapy, immunotherapy, or radiotherapy. They enable stimulus‐responsive therapies (photothermal, photodynamic, sonodynamic) activated by near‐infrared, light, or ultrasound, achieving potent synergistic ...

Interface‐Engineered Li–Ni–O/Ni Heterostructures With Tunable Vacancies on Biochar Enable Biomass‐to‐Hydrogen Conversion

Carbon Energy, EarlyView.
This study shows that lithium induces Li–Ni–O/Ni heterostructures on biochar, creating oxygen vacancies and optimal acid–base environments that enhance steam activation and suppress carbon deposition. These interfacial effects and synergistic modulation lead to high hydrogen yields at moderate temperatures, providing a scalable catalyst design strategy

Oxygen ionization rates at Mars and Venus: Relative contributions of impact ionization and charge exchange

Journal of Geophysical Research, 1993
Oxygen ion production rates above the ionopauses of Venus and Mars are calculated for photoionization, charge exchange, and solar wind electron impact ionization processes. The latter two require the use of the Spreiter and Stahara (1980) gas dynamic model to estimate magnetosheath velocities, densities, and temperatures.

Cross sections of charge exchange and ionization in O8+ +H collision in Debye plasmas

Physics of Plasmas, 2012
Charge exchange and ionization processes in O8+ +H collision system in a Debye plasma are studied using the classical trajectory Monte Carlo (CTMC) method in the collision energy ranging from 1 keV/amu to 500 keV/amu. Total charge exchange and ionization cross sections have been determined in both screening and unscreening environments.

A new type of ionizer for charge-exchange particle analyzer

Review of Scientific Instruments, 2018
The application of effective methods of charge-exchange neutral particle diagnostics to determine ion temperatures of plasmas in modern plasma installations is of great practical interest. In this paper, we propose a new type of ionizer based on ionization of neutral charge-exchange particles reflecting from metallic surfaces.

Charge exchange, excitation, and ionization via hidden avoided crossings

Physical Review A, 1990
General principles of the asymptotic theory of adiabatically slow atomic collisions are reviewed. Special emphasis is placed on analytic properties of adiabatic potential energy curves for complex values of internuclear separation. The significance of the complex branch points and hidden avoided crossings for the dynamics of one-electron collisional ...
