Removal of spacecraft-surface particulate contaminants by simulated micrometeoroid impacts [PDF]
A series of hypervelocity impacts has been conducted in an exploding lithium-wire accelerator to examine with a far-field holographic system the removal of particulate contaminants from external spacecraft surfaces subjected to micrometeoroid bombardment.

Advanced Energy and Sustainability Research, EarlyView.This work assesses the environmental impacts associated with the production of perovskite solar cells (PSCs) with two different architectures, mesoporous n‐i‐p and inverted p‐i‐n, using the life cycle assessment methodology. Results indicate that producing mesoporous n‐i‐p PSCs has higher environmental impacts than producing inverted p‐i‐n PSCs, due to

Advanced Energy and Sustainability Research, EarlyView.Using CO2‐rich polluting gases in greenhouse plant cultivation has proven to be a promising technique for stimulating plants while reducing emissions to the atmosphere. The use of an experimental biofilter proves to be effective in retaining most of the toxic particles. The alteration of physiological and metabolic parameters shows an adaptation of the

Clinical and Experimental Dental Research, Volume 8, Issue 6, Page 1331-1340, December 2022., 2022 Abstract Objectives Bone grafting is commonly used to reconstruct skeletal defects in the craniofacial region. Several bone augmentation models have been developed to evaluate bone formation using novel bone substitute materials. The aim of this study was to evaluate a surgical animal model for establishing a three‐dimensional (3D) grafting environment
