Thermally constructed stable Zn-doped NiCoO alloy structures on stainless steel mesh for efficient hydrogen production via overall hydrazine splitting in alkaline electrolyte.

Hydrogen has a high energy density of approximately 120 to 140 MJ kg, which is very high compared to other natural energy sources. However, hydrogen generation through electrocatalytic water splitting is a high electricity consumption process due to the sluggish oxygen evolution reaction (OER). As a result, hydrogen generation through hydrazine-assisted water electrolysis has recently been intensively investigated.

Exfoliation of 2D materials by saponin in water: Aerogel adsorption / photodegradation organic dye.

The biggest challenge for the paint industry is to clean the contaminated waste dye solution before it released into the water or to reuse it to create new paint and to protect the water from environmental pollution. Here in this work, exfoliating layered transition metal dichalcogenide materials prepare to the exfoliated 2D materials thin sheets in water with the assistance of natural saponin. Then, the three-dimensional (3D) MoS-aerogel composite was synthesized by using greenway exfoliated two-dimensional (2D) MoS thin sheets to form MoS-aerogel composite.

Marigold micro-flower like NiCoO grown on flexible stainless-steel mesh as an electrode for supercapacitors.

Nanostructured NiCoO is a promising material for energy storage systems. Herein, we report the binder-free deposition of porous marigold micro-flower like NiCoO (PNCO) on the flexible stainless-steel mesh (FSSM) as (PNCO@FSSM) electrode by simple chemical bath deposition. The SEM and EDS analysis revealed the marigold micro-flowers like morphology of NiCoO and its elemental composition.

Biomass-Mediated Synthesis of Cu-Doped TiO Nanoparticles for Improved-Performance Lithium-Ion Batteries.

Pure TiO and Cu-doped TiO nanoparticles are synthesized by the biomediated green approach using the Bengal gram bean extract. The extract containing biomolecules acts as capping agent, which helps to control the size of nanoparticles and inhibit the agglomeration of particles. Copper is doped in TiO to enhance the electronic conductivity of TiO and its electrochemical performance.

Ultrasound-assisted green economic synthesis of hydroxyapatite nanoparticles using eggshell biowaste and study of mechanical and biological properties for orthopedic applications.

Nanostructured hydroxyapatite (HAp) is the most favorable candidate biomaterial for bone tissue engineering because of its bioactive and osteoconductive properties. Herein, we report for the first time ultrasound-assisted facile and economic approach for the synthesis of nanocrystalline hydroxyapatite (Ca (PO ) (OH) ) using recycled eggshell biowaste referred as EHAp. The process involves the reaction of eggshell biowaste as a source of calcium and ammonium dihydrogen orthophosphate as a phosphate source.
