Repurposing and recycling wind turbine blades in the United States

Environmental Progress &Sustainable Energy, Volume 42, Issue 1, January/February 2023., 2023
Abstract Wind energy is increasing in popularity worldwide as a low‐cost, carbon‐free energy technology. As deployment continues to grow, owners will need to conduct planning for end‐of‐life strategies for the components that are large in volume, number, and not readily recyclable in the operational form.

Studying the Internal Ballistics of a Combustion Driven Potato Cannon using High-speed Video [PDF]

Eur. J. Phys. 34 (2013) 915-920, 2013
A potato cannon was designed to accommodate several different experimental propellants and have a transparent barrel so the movement of the projectile could be recorded on high-speed video (at 2000 frames per second). Both combustion chamber and barrel were made of polyvinyl chloride (PVC).

A Natural Lignification Inspired Super‐Hard Wood‐Based Composites with Extreme Resilience

Advanced Materials, EarlyView.
Super‐hard wood‐based composites (WBC) are designed and developed inspired by the mesoscale homogeneous lignification process intrinsic to tree growth. This innovative hybrid structure is achieved by leveraging the infusion of low‐molecular‐weight phenol formaldehyde resin into the cell walls of thin wood slices, followed by a unique multi‐layer ...

Experimental and numerical engine cycle setup for a dual fuel hydrogen, methane, and hythane with diesel to assess the effect of water injection and nozzle geometry

Environmental Progress &Sustainable Energy, Volume 42, Issue 1, January/February 2023., 2023
Abstract In this study, the potential of gaseous fuels such as hydrogen, methane, and hythane in combination with diesel fuel is assessed in a closed loop thermodynamic framework. An experimental test is conducted with basic diesel fuel and then the model is configured based on the realistic one‐cylinder diesel engine to evaluate the robustness and ...

Thermally driven hydrogen compression using metal hydrides

International Journal of Energy Research, Volume 46, Issue 15, Page 22049-22069, December 2022., 2022
This article overviews R&D activities related to the thermally‐driven hydrogen compression utilising metal hydrides. The focus is put on the interrelation between properties of metal hydride materials and their hydrogen compression performances, first, operating pressure – temperature range, process productivity and efficiency.
