Sustainable CO2 utilization and calcium carbonate recovery from calcium carbide wastewater

iScience
Summary: The hydration of calcium carbide for acetylene production generates calcium carbide residue (CCR), primarily as a calcium hydroxide slurry, often disposed of in ponds, increasing soil alkalinity and CCR wastewater.

Hot piston ring/cylinder liner materials: Selection and evaluation [PDF]

In current designs of the automotive (kinematic) Stirling engine, the piston rings are made of a reinforced polymer and are located below the pistons because they cannot withstand the high temperatures in the upper cylinder area.

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

Soil & 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

Moving From Micro‐ to Nanofibers Within Melt Electrospinning

Journal of Applied Polymer Science, EarlyView.
Controlling flow rate enables production of more nanofibers. This can be achieved even when electrospinning from viscous melts in a simple two‐plate geometry. Finding the optimal melt thickness to reduce flow without lowering the number of fiber‐forming jets is key.
