TiO6 as a Compensatory Structural Unit in Co‐Free, High‐Ni Layered Oxide for Durable Lithium‐Ion Batteries

Advanced Science, EarlyView.
Ti substitution stabilizes Co‐free high‐Ni layered oxides through both structural and electronic effects. TiO6 octahedra act as compensatory structural units that help interrupt cooperative Jahn–Teller distortion and suppress detrimental phase transitions, while the electron‐withdrawing inductive effect of Ti stabilizes the oxygen lattice. As a result,

A Decoy‐Receptor‐Armed Biomimetic Nanotherapeutic With Inherent Tropism for Conserved Pathogenic Macrophages for Treating Osteoarthritis and Intervertebral Disc Degeneration

Advanced Science, EarlyView.
A biomimetic doppelgänger nanosystem neutralizes extracellular inflammatory cytokines and silences intracellular pyroptosis, reprogramming pathogenic macrophages to attenuate both joint and spine degeneration. ABSTRACT Osteoarthritis (OA) and intervertebral disc degeneration (IVDD) are debilitating musculoskeletal disorders driven by shared ...

Stabilising the Lattice Oxygen Oxidation Mechanism Through Iridium Single Atoms in Chromium‐Doped Cobalt Iron Layered Double Hydroxides

Advanced Science, EarlyView.
Iridium single atoms and Cr doping synergistically activate and stabilise the lattice oxygen oxidation mechanism in CoFe layered double hydroxides. Electronic modulation enhances metal–oxygen covalency, suppresses over‐oxidation, and enables durable oxygen evolution, delivering high‐performance anion exchange membrane water electrolysis with ...

A Drug‐Gated, Modular STAb‐T Immunotherapy With External Control

Advanced Science, EarlyView.
Engineered STAb‐TON cells act as programmable living factories that continuously secrete inactive antibody modules, which assemble extracellularly into a functional T cell engager only upon small‐molecule administration. This externally controlled platform enables reversible, on‐demand regulation of antitumor immunity, establishing a new paradigm for ...

Explosive Plasma Instabilities

Physical Review Letters, 1969
The interaction of three monochromatic waves (two positive energy longitudinal waves and one negative energy wave) is investigated. When only the first-order nonlinear interactions are considered, an explosive instability occurs. However, this instability is stabilized by the higher order nonlinear interactions.

Instability of the cometary plasma tail — the instability in a plasma sheet

Research in Astronomy and Astrophysics, 2011
We consider the instability of the cometary plasma tail which is composed of a neutral sheet, two lobes of the ion tail and solar wind. The plasma is assumed to be highly conductive and incompressible. The unstable state yields a magnetic field which is perpendicular to the tail axis.

Anisotropic Temperature Plasma Instabilities

The Physics of Fluids, 1968
An anisotropic plasma exhibits a transverse instability due to the mutual attraction of the microscopic current elements. A detailed study is made of this instability in an electron-ion plasma without any external magnetic field. The system is characterized by a temperature tensor and described by a quasi-Maxwellian distribution function.

Plasma Electromagnetic Instabilities

The Physics of Fluids, 1963
A gyrotropic plasma with T∥/T⊥ ≡ γ < 1, where T⊥ and T∥ are the transverse and longitudinal temperatures, is shown to be unstable to a perturbation in the form of a transverse wave with a wave vector k such that k2 < k02 = {ωc2(1−γ)2 + ωp2(1−γ)/γ}/c2, ωc and ωp are the gyro and plasma frequencies.

Waves and Instabilities in a Finite Plasma

The Physics of Fluids, 1969
A dispersion relation is derived for electrostatic waves in a plasma confined between planes which perfectly reflect the particles but have no effect on the fields. A uniform magnetic field perpendicular to the planes is assumed. Both classical and quantum-mechanical derivations are given. In the quantum-mechanical derivation some terms appear which do

Instability of a strongly inhomogeneous plasma

Physical Review A, 1990
The stability of a plasma boundary in the presence of a powerful p-polarized electromagnetic wave is studied. It is shown that surface waves that are coupled to plasmons localized in the plasma-vacuum transition layer can be excited. The growth rate that is calculated turns out to be larger than the corresponding value obtained without taking nonlocal ...
