Advances in Low‐Temperature Dual‐Ion Batteries

ChemSusChem, 2023
AbstractFabricating rechargeable batteries for low‐temperature (LT) applications is highly desired at high altitudes/latitudes, aerospace/subsea exploration, and defense. Lithium‐ion batteries (LIBs) suffer from severe loss of capacity and energy/power density at sub‐zero temperatures caused by the sluggish kinetics.

A Metallic Room‐Temperature Oxide Ion Conductor

Angewandte Chemie International Edition, 2014
AbstractNanoparticles of Bi3Ir, obtained from a microwave‐assisted polyol process, activate molecular oxygen from air at room temperature and reversibly intercalate it as oxide ions. The closely related structures of Bi3Ir and Bi3IrOx (x≤2) were investigated by X‐ray diffraction, electron microscopy, and quantum‐chemical modeling. In the topochemically

Effects of temperature and temperature gradients on ion-sensitive microelectrodes

Journal of Neuroscience Methods, 1988
Ion-sensitive microelectrodes are widely used in studies of mammalian tissues. Often the tissue is maintained at 37 degrees C, some 10-15 degrees C above room temperature. The temperature difference between the room and the preparation was found to be capable of altering the measured ion potential by as much as 10 mV.

Low-temperature ion beam sputtered optical coatings

Applied Optics, 2023
In thin film deposition processes, the lower limit of the deposition temperature is determined by the used coating technology and the duration of the coating process and is usually higher than room temperature. Hence, the processing of thermally sensitive materials and the adjustability of thin film morphology are limited.

Variable-temperature ion–implantation cryostat

Review of Scientific Instruments, 1980
A versatile low-temperature apparatus for studies using ion beams in an ultrahigh vacuum environment is described. By providing variable-temperature operation from ∼2–300 K, the facility can be used for a variety of studies. These have included low-temperature ion implantations for the production of metastable superconducting systems, thermal-annealing

Room Temperature Fluoride Ion Batteries

ECS Meeting Abstracts, 2019
Fluorine is highly electronegative (+2.84 V vs. SHE) element and possess low weight. Fluoride is monovalent, and it has high charge density. Consequently, it enables high ionic conductivity similar to Li+ in certain solids. However, fluorine is a corrosive and toxic gas, which forbids it as one of the electrodes.

Very high-temperature ion source

Review of Scientific Instruments, 2004
This paper represents the next step in the development and research of high-temperature ion sources of refractory metals. The very high-temperature ion source is created on the basis of the already produced high-temperature source for palladium ions. The basic difficulties of such device designing, the successes, and perspective tasks are presented.

Low-temperature growth and ion-assisted deposition

Physical Review B, 1995
Using standard molecular-dynamics methods, we have simulated silicon molecular-beam epitaxy on a (100) substrate, subject to a second beam of low-energy argon atoms. We find that the presence of the ion beam has an important effect on the structure of the deposits formed: good crystalline material forms at significantly lower temperatures, where ...

Ion and Temperature Sensitive Polypeptide Block Copolymer

Biomacromolecules, 2014
A poly(ethylene glycol)/poly(L-alanine) multiblock copolymer incorporating ethylene diamine tetraacetic acid ([PA-PEG-PA-EDTA(m)) was synthesized as an ion/temperature dual stimuli-sensitive polymer, where the effect of different metal ions (Cu(2+), Zn(2+), and Ca(2+)) on the thermogelation of the polymer aqueous solution was investigated.

Temperature anisotropy stabilization of ion temperature gradient instabilities

Physics Letters A, 1988
Abstract The effect of ion temperature anisotropies on the ion temperature gradient instability (“ion mixing mode”) is investigated in a shearless slab geometry. The roles played by the parallel and perpendicular (to the equilibrium magnetic field) components of the temperature are described and modified stability diagrams are presented.
