Ion implantation induced phase transformation and the crystal structure of a series ion implanted β-Ga 2 O 3 samples were studied using electron diffraction, high resolution transmission microscopy, scanning microscopy. In contrast to previous reports suggesting an orthorhombic κ-phase, we show that for 28 Si + , 58 Ni stoichiometric 69 Ga / 16 -implantations, monoclinic β-phase transforms cubi...

Tin-based perovskites are promising alternative absorber materials for lead-free perovskite solar cells but need strategies to avoid fast tin (Sn) oxidation. Generally, this reaction can be slowed down by the addition of fluoride (SnF2) precursor solution, which also improves layer morphology. Here, work analyzes spatial distribution additive within formamidinium triiodide (FASnI3) films deposi...

NaPO2F2 prepared via a facile two-step reaction was characterized by structural analysis and used as an additive for sodium-ion batteries. The addition of formed highly Na+-conductive SEI layer, which enhanced electrode performance.

We present a non-linear model transformation for adapting Gaussian Mixture HMMs using both static and dynamic MFCC observation vectors to additive noise and constant system tilt. This transformation depends upon a few compensation coefficients which can be estimated from channel distorted speech via Maximum-Likelihood stochastic matching. Experimental results validate the effectiveness of the a...

The beneficial role of lithium bis(trimethylsilyl) phosphate (LiTMSP), which may act as a novel bifunctional additive for high-voltage LiNi1.5Mn0.5O4 (LNMO)/graphite cells, has been investigated. LiTMSP is synthesized by heating tris(trimethylsilyl) with tert-butoxide. cycle performance LNMO/graphite cells at 45 °C significantly improved upon incorporation (0.5 wt %). Nuclear magnetic resonance...
