Determination of contact angle hysteresis of water microdroplets evaporating on hydrolyzed PET foils [PDF]

Acta Montanistica Slovaca, 2013
Moderately hydrophobic surfaces of PET foils were gradually hydrophilized by their immersion in NaOH solutions of increasing concentration. Then, the contact angle and geometric factors of microliter water drops, deposited on these polymer surfaces, were

Functionalization of a Hydrophilic Commercial Membrane Using Inorganic-Organic Polymers Coatings for Membrane Distillation

Applied Sciences, 2017
Membrane distillation is a thermal separation technique using a microporous hydrophobic membrane. One of the concerns with respect to the industrialization of the technique is the development of novel membranes.

Joining of Metal to Ceramic Plate Using Super-Spread Wetting

Metals, 2020
Ceramic-metal composites with novel performance are desirable materials; however, differences in their properties result in difficulties in joining. In this study, the joining of metal to ceramic is investigated.

Grain Boundary Wetting and Material Performance in an Industrial EZ33A Mg Cast Alloy [PDF]

Archives of Metallurgy and Materials, 2019
The grain boundary wetting phase transition in an industrial EZ33A cast alloy is studied. 12% of the grain boundaries are completely wetted at the temperature slightly higher than the eutectic transformation temperature (530°C).

Impact of a senior research thesis on students' perceptions of scientific inquiry in distinct student populations

FEBS Open Bio, EarlyView.
This study addressed how a senior research thesis is perceived by undergraduate students. It assessed students' perception of research skills, epistemological beliefs, and career goals in Biochemistry (science) and BDC (science‐business) students. Completing a thesis improved confidence in research skills, resilience, scientific identity, closed gender‐

Lotus Effect and Friction: Does Nonsticky Mean Slippery?

Biomimetics, 2020
Lotus-effect-based superhydrophobicity is one of the most celebrated applications of biomimetics in materials science. Due to a combination of controlled surface roughness (surface patterns) and low-surface energy coatings, superhydrophobic surfaces ...

Mycobacterial cell division arrest and smooth‐to‐rough envelope transition using CRISPRi‐mediated genetic repression systems

FEBS Open Bio, EarlyView.
CRISPRI‐mediated gene silencing and phenotypic exploration in nontuberculous mycobacteria. In this Research Protocol, we describe approaches to control, monitor, and quantitatively assess CRISPRI‐mediated gene silencing in M. smegmatis and M. abscessus model organisms.

Rapid Microbial Dynamics in Response to an Induced Wetting Event in Antarctic Dry Valley Soils

Frontiers in Microbiology, 2019
The cold deserts of the McMurdo Dry Valleys (MDV), Antarctica, host a high level of microbial diversity. Microbial composition and biomass in arid vs. ephemerally wetted regions are distinctly different, with wetted communities representing hot spots of ...

Characterization of Clinical Phenotype to Glial Fibrillary Acidic Protein Concentrations in Alexander Disease

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective To determine the concentration of glial fibrillary acidic protein (GFAP) in cerebrospinal fluid (CSF) and plasma in Alexander disease (AxD) and whether GFAP levels are predictive of disease phenotypes. Methods CSF and plasma were collected (longitudinally when available) from AxD participants and non‐AxD controls.

Advances in reactive air wetting and brazing of engineering ceramics

Journal of Advanced Ceramics
The reactive air brazing (RAB) process of ceramics was developed in the early 2000s because high-temperature electrochemical devices, such as solid oxide fuel cells (SOFCs), gas separators, reformers, and ion transport membrane systems, are increasingly ...
