X-ray absorption study of Ti-bearing silicate glasses [PDF]
, 1994 Ti K-edge XANES spectra have been collected on a series of Ti-bearing silicate glasses with metasilicate and tetrasilicate compositions. The intensity of the preedge feature in these spectra has been found to change with glass composition and varies from

Dynamics of water molecules in an alkaline environment
The Journal of Chemical Physics, 2002 We report on a two-color mid-infrared pump–probe spectroscopic study of the dynamics of the OH stretch vibrations of HDO molecules dissolved in a concentrated (10 M) solution of NaOD in D2O. We observe that spectral holes can be created in the broad OH stretch absorption band that change neither position nor width on a picosecond time scale.

Harnessing Fungal Biowelding for Constructing Mycelium‐Engineered Materials
Advanced Engineering Materials, EarlyView.Mycelium‐bound composites (MBCs) offer low‐carbon alternatives for construction, yet interfacial bonding remains a critical challenge. This review examines fungal biowelding as a biocompatible adhesive, elucidating mycelium‐mediated interfacial mechanisms and their role in material assembly. Strategies to optimize biowelding are discussed, highlighting

Bacterial Diversity in a Nonsaline Alkaline Environment: Heterotrophic Aerobic Populations [PDF]
Applied and Environmental Microbiology, 2004 ABSTRACT Heterotrophic populations were isolated and characterized from an alkaline groundwater environment generated by active serpentinization, which results in a Ca(OH) 2 -enriched, extremely diluted groundwater with pH 11.4.

Sterol-Response Pathways Mediate Alkaline Survival in Diverse Fungi
mBio, 2020 The ability for cells to maintain homeostasis in the presence of extracellular stress is essential for their survival. Stress adaptations are especially important for microbial pathogens to respond to rapidly changing conditions, such as those ...

Environmentally induced physiological responses that determine fish survival and distribution: a review [PDF]
, 2005 Limitation to an aqueous habitat is the most fundamental physiological constraint imposed upon fish, phrases such as 'like a fish of water', convey our acceptance of the general unsuitability of fish for terrestrial existence.
