In Situ High‐Resolution Imaging of Live Treponema pallidum Using Catalyst‐Free Bioorthogonal Strategy

Aggregate, EarlyView.
Schematic illustration of labeling live Treponema pallidum using an activated alkyne‐modified AIE chromophore via catalyst‐free bioorthogonal reaction. ABSTRACT Treponema pallidum (T. pallidum) causes syphilis, a sexually transmitted disease that leads to multi‐organ complications and even death. The lack of technology for tracing live T.

Preparation of Polyester-Based Metal-Cross Linked Polymeric Composites as Novel Materials Resistant to Bacterial Adhesion and Biofilm Formation

Molecules, 2011
Bacterial biofilms constitute an extremely resistant form of bacterial colonization with dire health and economical implications. Towards achieving polymeric composites capable of resisting bacterial adhesion and biofilm formation, we prepared five 2,6 ...

Efficient Removal of Cd(II) and PB(II) Ions Using Innovatively Functionalized Poly(2,5‐Dihydro‐2,5‐Dimethoxyfuran) for Water Treatment Applications

Journal of Applied Polymer Science, EarlyView.
Synthesis and surface functionalization of pDHMF for enhanced Cd(II) and Pb(II) adsorption from water. ABSTRACT In this work, a novel polymeric adsorbent was synthesized via the cationic polymerization of cis, trans‐2,5‐dihydro‐2,5‐dimethoxyfuran (DHMF), a renewable monomer derived from biomass. To improve its adsorption performance, synthesized poly(2,

INFRARED SPECTROPHOTOMETRY, A RAPID AND EFFECTIVE TOOL FOR CHARACTERIZATION OF DIRECT DISTILLATION NAPHTHAS La espectrofotometría infraroja, una herramienta rápida y efectiva para la caracterización de naftas de destilación directa

CT&F Ciencia, Tecnología & Futuro, 2005
The characterization of naphtha obtained by direct distillation of medium and heavy crude oils is often limited by the low yield of these fractions. Gas chromatography is a technique that allows a complete determination of the chemical composition of ...

Broadband Transmission Spectroscopy of the super-Earth GJ 1214b suggests a Low Mean Molecular Weight Atmosphere

, 2011
We used WIRCam on CFHT to observe four transits of the super-Earth GJ 1214b in the near-infrared. For each transit we observed in two bands nearly-simultaneously by rapidly switching the WIRCam filter wheel back and forth for the duration of the ...

A New Era for Using Natural Pigments: The Case of the C50 Carotenoid Called Bacterioruberin

Biotechnology and Applied Biochemistry, EarlyView.
ABSTRACT Haloarchaea are extremophilic microorganisms belonging to the Archaea domain that require high salt concentrations to live, thus inhabiting ecosystems like salty ponds, salty marshes, or extremely salty lagoons. They are more abundant and widely distributed worldwide than initially expected.
