Silicon carbide fiber reinforced strontium aluminosilicate glass-ceramic matrix composite [PDF]

open access: yes
A SrO-Al2O3 - 2SrO2 (SAS) glass ceramic matrix is reinforced with CVD SiC continuous fibers. This material is prepared by casting a slurry of SAS glass powder into tapes.

Computational Discovery of a Novel Yttrium Silicide as an Ambient Pressure Superconductor

open access: yesAnnalen der Physik, EarlyView.
We predict a tetragonal YSi₆ whose dumbbell‐silicon network strengthens electron‐phonon coupling, yielding a record 8.4 K critical temperature for binary yttrium silicides. The finding broadens silicide superconductivity design space and spotlights YSi₆ as a candidate material for quantum‐circuit and qubit technologies.

Impact of calcium sulphate and calcium carbide on nitrogen use efficiency of wheat in normal and saline sodic soils

open access: yesSoil & Environment, 2009
pot experiment was conducted to study the effect of calcium as CaSO4 or CaC2 (20 mg Ca kg-1 of soil from each source) on N use efficiency of wheat (Triticum aestivum L. var. Inqlab-91) under normal (ECe=0.7 dS m-1, SAR=4.37 and pH=8.1) and saline-sodic

From solid waste to subgrade stabilizer: lithium slag-calcium carbide residue geopolymer for silty clay subgrade stabilization

open access: yesResults in Engineering
In seasonally frozen regions, silty clay subgrades often suffer from frost heave, thaw settlement, and mud pumping, which jeopardize road stability.
