Stable carbon isotope variations in surface bloom scum and subsurface seston among shallow eutrophic lakes [PDF]

open access: yes, 2007
Carbon stable isotope analysis of surface bloom scum and subsurface seston samples was conducted in shallow eutrophic lakes in China during warm seasons from 2003 to 2004. delta C-13 values of bloom scum were always higher (averaged 5 parts per thousand)

Gas‐Selective Remote Plasma Engineering of WO3 Photoanodes for Solar Water Splitting

open access: yesAdvanced Materials Interfaces, EarlyView.
Gas‐selective remote plasma treatment tunes the near‐surface defect chemistry of WO3 photoanodes without altering their bulk structure. Ar plasma generates the most oxygen‐vacancy‐rich surface and the highest W5+ content, delivering the strongest photocurrent.

Additive‐Manufactured, Multifunctional Bioreactor Technology for Dynamic Culture of 3D Bioprinted Tissue Models

open access: yesAdvanced Materials Technologies, EarlyView.
We introduce an additively manufactured bioreactor with a perfusion flow system and integrated temperature and pH sensors for skeletal muscle tissue biofabrication. The bioreactor's performance was evaluated by assessing the viability, spreading of the myoblast cells in a printed scaffold, and contraction of the isolated murine musculi interossei ...

Multiscale Microscopy via Automation: Dual Magnification Environmental Scanning Electron Microscopy Imaging by Frame Alternation

open access: yesAdvanced Materials Technologies, EarlyView.
An automation interface for environmental scanning electron microscopy (ESEM) enables simultaneous, interlaced data sets via frame‐by‐frame parameter changes. Demonstrated on oscillatory hydrogen oxidation over cobalt (Co) foil, dual‐magnification imaging bridges mesoscopic to microscopic length scales, capturing alternating views of surface dynamics ...

Ultraviolet Radiation Sensitivity in Cave Bacteria: Evidence of Adaptation to the Subsurface? [PDF]

open access: yesInternational Journal of Speleology, 2009
We hypothesize that a reduced capacity to withstand or repair cellular damage from ultraviolet radiation may be present in caveadaptedmicroorganisms that never experience such conditions.
