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 Novel Modified Petroresin Particle (MPRP) With Enhanced Oil–Water Selectivity for Cold Production in Heavy Oil Reservoirs

Advanced Functional Materials, EarlyView.
A novel oil–water selective conformance control agent, MPRP, is prepared via hydrophilic grafting and mechanical granulation. MPRP uniformly disperses in water, cohesively expands upon aging, and readily dissolves in the oil phase. During conformance control, it selectively aggregates in water channeling pathways to form effective plugs without ...

Alternative Fuels for Internal Combustion Engines

Energies, 2020
The recent transport electrification trend is pushing governments to limit the future use of Internal Combustion Engines (ICEs). However, the rationale for this strong limitation is frequently not sufficiently addressed or justified. The problem does not
