Laser‐Induced Graphene from Waste Almond Shells

Advanced Functional Materials, EarlyView.
Almond shells, an abundant agricultural by‐product, are repurposed to create a fully bioderived almond shell/chitosan composite (ASC) degradable in soil. ASC is converted into laser‐induced graphene (LIG) by laser scribing and proposed as a substrate for transient electronics.

A COMPARATIVE ANALYSIS OF NUTRIENT CONTENT OF SOILS SAMPLED FROM MID OF FOUR PLANTS AND DRIP CIRCLE OF COFFEE PLANTATIONS IN INDIA [PDF]

Russian Journal of Agricultural and Socio-Economic Sciences
Coffee growers often apply fertilizers very close to the plants, which results in accumulation of nutrients in one place leading to poor nutrient use efficiency, whereas soil sampling is done in the middle of four plants.

Laser‐Welded Cellulose‐Carbon Nanotube Nanocomposites as a 3D Scaffold of Si Anodes for High‐Performance Lithium‐Ion Batteries

Advanced Functional Materials, EarlyView.
A Si anode comprising entangled networks of cellulose and SWCNT (C‐CNT) nanocomposites as an anode electrode for a high‐performance LIB is realized by fully utilizing the generated microstructure of a novel conductive 3D scaffold via a low‐temperature and eco‐friendly process. Additionally, localized heating via photo‐thermal conversion can be utilized
