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

Machine‐Learning‐Enabled Wood with Nanopump Functionalization for Solar Interfacial Evaporation

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This study employed machine learning to design an iron‐cobalt‐carbon‐wood photothermal material, achieving high‐efficiency evaporation at 2.807 kg m−2 h−1 and excellent salt resistance. The integrated system increased the daily water production efficiency of solar distillation by 1.5 times, providing an innovative solution for sustainable seawater ...

Engineering Nanoclay Edges to Construct Effective Polysulfide‐Trapping Interface for Markedly Enhanced Electrochemical Energy Storage

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A capsule‐shaped silicate clay (H‐ATP‐N2) rich in protonated edge hydroxyl groups (‐OH2+) is synthesized through a two‐step process involving microwave‐assisted acid treatment and N2 plasma etching to fibrous natural attapulgite. The H‐ATP‐N2 host inhibits the shuttle effect owing to the dominant adsorption mechanism–Lewis acid–base interaction between
