A gateway for ion transport on gas bubbles pinned onto solids

open access: yesCommunications Chemistry, 2021
Electrocatalytic reactions depend on ion transport phenomena within the electric double layer, but the electrochemical response of single gas bubbles that form on catalyst surfaces remains unclear.

Hydroxyapatite-modified micro/nanostructured titania surfaces with different crystalline phases for osteoblast regulation

open access: yesBioactive Materials, 2021
Surface structures and physicochemical properties critically influence osseointegration of titanium (Ti) implants. Previous studies have shown that the surface with both micro- and nanoscale roughness may provide multiple features comparable to cell ...

A systematic review comparing the macrophage inflammatory response to hydrophobic and hydrophilic sandblasted large grit, acid‐etched titanium or titanium–zirconium surfaces during in vitro studies

open access: yesClinical and Experimental Dental Research, 2023
Objectives Macrophages are among the first cells to interact with the dental implant surface and are critical regulators for controlling the immune response toward biomaterials.

Nano-Topographical Control of Ti-Nb-Zr Alloy Surfaces for Enhanced Osteoblastic Response

open access: yesNanomaterials, 2021
Nano-scale surface roughening of metallic bio-implants plays an important role in the clinical success of hard tissue reconstruction and replacement. In this study, the nano-topographical features of titanium-niobium-zirconium (TNZ) alloy surfaces were ...

A statistical response surface generator [PDF]

open access: yesProceedings of the 7th conference on Winter simulation - WSC '74, 1974
Small scale special purpose analog simulators are finding many applications as teaching aids in the classroom. One type of simulator design is currently being used in graduate level statistics courses at the University of Delaware. It was developed primarily for teaching Statistical Response Surface Technology.Statistical Response Surface Technology ...

Enteropathogenic E. coli shows delayed attachment and host response in human jejunum organoid‐derived monolayers compared to HeLa cells

open access: yesFEBS Letters, EarlyView.
Enteropathogenic E. coli (EPEC) infects the human intestinal epithelium, resulting in severe illness and diarrhoea. In this study, we compared the infection of cancer‐derived cell lines with human organoid‐derived models of the small intestine. We observed a delayed in attachment, inflammation and cell death on primary cells, indicating that host ...

Organoids in pediatric cancer research

open access: yesFEBS Letters, EarlyView.
Organoid technology has revolutionized cancer research, yet its application in pediatric oncology remains limited. Recent advances have enabled the development of pediatric tumor organoids, offering new insights into disease biology, treatment response, and interactions with the tumor microenvironment.

Loci That Control Nonlinear, Interdependent Responses to Combinations of Drought and Nitrogen Limitation

open access: yesG3: Genes, Genomes, Genetics, 2018
Crop improvement must accelerate to feed an increasing human population in the face of environmental changes. Including anticipated climatic changes with genetic architecture in breeding programs could better optimize improvement strategies. Combinations
