Abstract. The increasing share and expansion of miniature devices requires the mastery parts production, including metal parts. In microforming, due to conditions mechanical similarity, aim is use materials with smallest grain. Ultra-fine-grained metals (UFG) fulfill this requirement. These can be obtained, inter alia, in SPD processes such as ECAP. work uses extension based on ECAP additional ...

Transition metal sulfides have a great potential for energy storage due to the pronouncedly higher capacity (owing to conversion to metal or even alloy) than traditional insertion electrode materials. However, the poor cycling stability still limits the development and application in lithium and sodium ion batteries. Here, taking SnS as a model material, a novel general strategy is proposed to ...

Solid-state lithium (Li) metal batteries are prominent among next-generation energy storage technologies due to their significantly high energy density and reduced safety risks. Previously, solid electrolytes have been intensively studied and several materials with high ionic conductivity have been identified. However, there are still at least three obstacles before making the Li metal foil-bas...

Abstract Structural carbon fibre composite batteries are a type of multifunctional that combine the energy storage capability battery with load-carrying ability structural material. To extract current from cell, collectors needed. However, expensive, hard to connect electrode material and add mass system. Further, attaching collector must not affect electrochemical properties negatively or requ...

HIHEX experiments at GSI-Darmstadt are carried out for investigation of material properties and processes in matter under intense heavy ion beam loading. In these experiments [1, 2], a heavy ion beam of U with an initiation energy of 350AMeV was used to irradiate a lead foil with a thickness of 250 μm. The temperature of the expanded part of the foil was measured by a pyrometer through the tran...

Backlit pinhole radiography used with ungated film as a detector creates x-ray radiographs with increased resolution and contrast. Current hydrodynamics experiments on the OMEGA Laser use a three-dimensional sinusoidal pattern as a seed perturbation for the study of instabilities. The structure of this perturbation makes it highly desirable to obtain two simultaneous orthogonal backlighting vie...

Non-radiative surface plasma oscillations in a semi-infinite metal are quantized by using a hydrodynamic jellium model for electrons in the metal. In consequence of the quantization, the electronSF (surface plasmon) vertex function is obtained for the overall region of the surface plasmon wave vector k. In the electrostatic limit, it coincides with the usual electrostatic vertex function obtain...

Stable Li Metal Batteries Ordered micro-grooves are prepared by femtosecond laser on Cu foil for lithium metal battery. The deposition of can be directed the to form ordered and dense arrays. This idea tuning nucleation sites current collector significantly enlighten future work high-energy-density anode-free full cells.

This paper describes a novel technique for joining similar and dissimilar metal foils, namely micro clinching with cutting by laser shock forming. A series of experiments were conducted to study the deformation behavior of single layer material, during which many important process parameters were determined. The process window of the 1060 pure aluminum foils and annealed copper foils produced b...

A new methodology which combines reactor experiments and numerical modelling to derive kinetic rates of solid-gas heterogeneous reactions in a stagnation point flow reactor (SPFR) is developed and used to investigate the effects of small concentrations of H2S and SO2 on the lean catalytic combustion of methane on precious metal catalysts. The activity of polycrystalline Pt foil, then Pt, Rh and...
