Swelling Behavior of a Crosslinked pHEMA Hydrogel in pH and Salt Environments

Journal of Applied Polymer Science, EarlyView.
The swelling behavior of non‐ionic crosslinked poly hydroxyethyl methacrylate (pHEMA) is investigated in alkaline, acidic, and electrolyte solutions. The swelling behavior is affected by crosslinker concentration, pH, swelling time, and specific Ion‐pHEMA‐water interactions.

PRESENCE OF hemA-LIKE AND hemT-LlKE GENES IN A JSUMBER OF ANOXYGENIC PHOTOSYNTHETIC BACTERIAL ISOLATES FROM INDONESIA AND SOIL SAMPLES FROM BOGOR AREA

Biotropia: The Southeast Asian Journal of Tropical Biology, 2011
The Rhodobacter sphaeroides hemA and hemT are known to encode a distinct 5-aminolevulinic acid (ALA)-synthase isozyme. This enzyme catalyzes the first and rate limiting step in ALA biosynthesis through the C4 pathway.

Europium Doped Atomically Precise Bismuth Oxido Nanoclusters as Molecular Building Blocks for Photoluminescent Hybrid Materials

Chemistry – A European Journal, EarlyView.
Europium doping of bismuth oxido nanoclusters (BiO‐NCs) provides stable hosts for Eu3+ in an asymmetric coordination environment, which in turn results in an intense 5D0→7F0 transition and long luminescence lifetimes. Transparent hybrid materials showing characteristic red photoluminescence are accessible via radical copolymerisation of these soluble ...

CytoScan: Automated Detection of Technical Anomalies for Cytometry Quality Control

Cytometry Part A, EarlyView.
ABSTRACT Studies evaluating cellular phenotypes by cytometry techniques are increasingly facing analytical challenges due to the multitudes of samples and parameters that are evaluated concurrently. Spurious technical effects resulting from a lack of standardization can affect marker distributions and further complicate multi‐sample analyses.

Charting Water‐in‐Natural‐Salt (WiNS) Electrolytes. Part I: Effect of Anion's Alkyl Tail Length

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
At 20 m, potassium carboxylates from formate to butyrate reveal anion tail‐controlled nanostructure. SAXS shows a pre‐peak shifting to lower q with chain length. Molecular dynamics reproduces S(q) and attributes it to concentration fluctuations forming bicontinuous segregation.
