Thermal barrier coatings (TBC) are important materials applied to hot part components of
aero-engines in order to improve their service temperature. Increasing inlet temperature is …

Under excitation at 980 nm, Tm3+ may emit ultraviolet, blue, and red light, and Ho3+ may
emit green light through multiphoton upconversion processes in Yb/Tm/Ho codoped …

Carbon/carbon composites modified by HfC–SiC, HfC–SiC: ZrC–SiC (2: 1), HfC–SiC: ZrC–
SiC (1: 2) and ZrC–SiC were ablated by oxyacetylene torch to investigate the effect of doped …

The dehydrogenation of CH 3 CH 2 OH to produce CH 3 CHO and H 2 is crucial for
generating valuable chemicals. This study uses density functional theory (DFT) and …

The capture and storage of CO2 are of growing interest in atmospheric science since
greenhouse gas emission has to be reduced considerably in the near future. The present …

We report on optical properties of various polymorphs of hafnia predicted within the
framework of density functional theory. The full potential linearised augmented plane wave …

An amorphous Al 2 O 3 (a-Al 2 O 3)/MoS 2 interface has attracted much attention because of
its unique properties. In this study, the interface behaviors under non-strain and biaxial strain …

The pressure induced theoretical investigations of electronic, optical and elastic constants of
cubic zirconia (c-ZrO 2) are estimated under the effect of hydrostatic pressure (0–40 GPa) by …

Polymer-derived ceramics (PDCs) are important ceramics for high temperature
electromagnetic wave (EMW) absorption because of their tunable conductivity with the …

Cubic ZrO 2 has strong mechanical properties, however, its weak electronic and optical
properties limit practical applications. We demonstrate Cr-doping can be an efficient …
