Chemical Engineering &Technology, Volume 46, Issue 1, Page 110-117, January 2023., 2023 In hydraulic axial piston pumps, conventionally leaded brass is used right against steel. In order to renounce lead and find a lead‐free alternative, high‐speed laser material deposition is employed to apply a carbide‐reinforced anti‐wear coating. Based on the experiences of prior tests, it demonstrates that this coating also works in a state‐of‐the ...

Hydrophilic Chitosan Derivatives: Synthesis and Applications
Chemistry – A European Journal, Volume 28, Issue 67, December 1, 2022., 2022 A benign and low‐cost alternative for fossil‐fuel‐sourced polymers, chitosan has tremendous potential because of its bioactivity, biocompatibility, biodegradability, and low toxicity. Synthetic pathways for chitosan derivatives with improved water solubility, and their associated applications, are explored. With the change in global direction towards a

Stratospheric Albedo Modification by Aerosol Injection [PDF]
Energy and Environmental Science 3, 1634--1644 (2010), 2009 This paper reviews and develops the proposal, widely discussed but not examined in detail, to use stratospheric aerosols to increase the Earth's albedo to Solar radiation in order to control climate change. The potential of this method has been demonstrated by the "natural experiments" of volcanic injection of sulfate aerosols into the stratosphere ...

Aerosol Jet Printing of Superhydrophobic Surfaces
Advanced Materials Technologies, EarlyView.A novel method for creating spatially programmable superhydrophobic surfaces using an aerosol jet printer is presented. This technique allows precise deposition of micrometer‐sized polymer solution droplets onto a substrate, with control over surface morphology, microstructure, and wettability through solvent evaporation modulation.

Canadian contributions to environmetrics
Canadian Journal of Statistics, Volume 50, Issue 4, Page 1355-1386, December 2022., 2022 Abstract This article focuses on the importance of collaboration in statistics by Canadian researchers and highlights the contributions that Canadian statisticians have made to many research areas in environmetrics. We provide a discussion about different vehicles that have been developed for collaboration by Canadians in the environmetrics context as ...
