Using QCM‐D for Real‐Time Analysis of Cell Adhesion Dynamics at Biointerfaces

Advanced Materials Interfaces, EarlyView.
This study explores adhesion of human fibroblasts to functionalized biomaterial surfaces. Quartz crystal microbalance with dissipation (QCM‐D) is used to measure cell responses in real time. The QCM‐D signalis correlated with changes in cell morphology and focal adhesion kinase (FAK) activation. This data shows a positive correlation between the energy

A Systematic Study of Staphylococcus aureus Biofilm Formation on Thiol‐Ene Polymers: Toward the Development of Microfluidic Bacterial Biofilm Models

Advanced Materials Interfaces, EarlyView.
This work presents a systematic characterization of an emerging polymer platform, off‐stoichiometry thiol‐ene, in terms of its ability to support the formation, growth, and metabolic activity of Staphylococcus aureus biofilms. The findings indicate that thiol‐enes promote S.

Filtered bicarbonate and plasma pH as determinants of renal bicarbonate reabsorption

Kidney International, 1981
To examine if bicarbonate reabsorption varies with filtered bicarbonate and plasma pH, we infused anesthetized dogs i.v. with sodium chloride and sodium bicarbonate to alter plasma bicarbonate concentration (PHCO3) without changing hematocrit. Examinations in five dogs over a wide range of glomerular filtration rates (GFR) during ethacrynic acid ...

Proton Conduction of a Hydrothermally Synthesized Hexaazatriphenylene‐Based Covalent Organic Framework

Advanced Materials Interfaces, EarlyView.
A quinone‐functionalized hexaazatriphenylene‐based covalent organic framework (HAQ‐COF) is synthesized, making HAQ‐COF a promising polymer electrolyte membrane material for polymer electrolyte fuel cells. HAQ‐COF exhibits high water retention at room temperature and atmospheric pressure, along with high thermal stability.

4D Printed Self‐Deploying Bio‐Based Scaffolds for the Regeneration of Endoluminal Tissue

Advanced Materials Technologies, EarlyView.
A bilayer self‐deploying tubular C‐shaped scaffold, made of natural polymers and triggerable by humidity, is fabricated via 4D printing for the regeneration of gastro‐intestinal tissue. The choice of the materials and their spatial arrangement is guided by physical and biological evaluation, whereas the geometry of the structure is optimized through ...

The Case for a Hot Archean Climate and its Implications to the History of the Biosphere [PDF]

arXiv, 2015
The case for a much warmer climate on the early Earth than now is presented. The oxygen isotope record in sedimentary chert and the compelling case for a near constant isotopic oxygen composition of seawater over geologic time support thermophilic surface temperatures prevailing in the Archean, with some support for hot conditions lasting until about 1.
