Vanadium-modified molecular sieves: preparation, characterization and catalysis

Química Nova, 2009
Vanadium-containing molecular sieves are redox catalysts and are good candidates as substitutes for oxide-supported V2O5 in a number of reactions. These materials have the advantage of presenting better dispersion of vanadium species, as well as shape ...

YIPFα1A expression is regulated by multilayered molecular mechanisms

FEBS Open Bio, EarlyView.
YIPFα1A, a five‐pass Golgi protein, is regulated at multiple layers. (1) Rare‐codon enrichment drives translation‐coupled mRNA decay. (2) A proximal 3′‐UTR element stabilizes mRNA. (3) A distal 3′‐UTR element included by alternate poly(A) site usage represses translation, which can be overridden by the proximal 3′‐UTR element.

Application Research of Ion-Exchange Molecular Sieves in Oxygen-Argon Separation

He huaxue yu fangshe huaxue
Inert gas argon has important applications in the fields of daily life, industrial manufacture and nuclear environmental monitoring. The key to its application is to selectively and efficiently separate and purify Ar from complex gas components. However,

Optimizing photoactivation of PA‐mCherry for optical pooled CRISPR screens

FEBS Open Bio, EarlyView.
Photoactivatable PA‐mCherry finds widespread use to optically tag individual cells. However, confocal 405 nm UV laser‐scanning (normal scan) is much less efficient than widefield UV illumination, limiting the use of PA‐mCherry on confocal instruments. We remedy this limitation by reporting that rapid and repeated confocal scanning with a low‐intensity,

Synthesis, Characterization and Catalytic Properties of Microporous Cobalt Aluminosilicate (CoLTL) Molecular Sieves

Eurasian Chemico-Technological Journal, 2008
Thermally stable divalent cobalt substituted microporous aluminosilicate (CoLTL) molecular sieves were synthesized and characterized. These studies revealed isomorphous substitution of divalent cobalt in tetrahedral framework of LTL structure.

The Influence of Solvents on the Liquid-Phase Adsorption Rate of n-Hexane in 5A Molecular Sieves

Adsorption Science & Technology, 2009
The main branched hydrocarbons in naphtha are isomeric hydrocarbons, cyclo-paraffins and aromatics. The naphthenic base naphtha has a high content of cyclo-paraffins while aryl naphtha has a correspondingly high content of aromatics.

Small RNA pathways in mammalian oocytes

FEBS Open Bio, EarlyView.
Three distinct small RNA pathways operate in mammalian oocytes: RNAi interference (RNAi), the microRNA (miRNA) pathway, and the PIWI‐associated RNA (piRNA) pathway. These pathways use small RNAs to guide sequence‐specific repression and contribute to oocyte biology by targeting genes and mobile elements or appear insignificant since different ...

Study on the Synthesis Method of [11C]Methionine Using Molecular Sieve as Desiccant

Korean Journal of Clinical Laboratory Science
[11C]Methionine is used widely for brain tumor diagnosis via positron emission tomography. Moisture generated during the synthesis of [11C]methionine reduces the synthesis yield. Therefore, a desiccant is used to remove moisture.

Pathways and pitfalls: a qualitative study of student experiences in biomedical science education

FEBS Open Bio, EarlyView.
Biomedical science students from underrepresented backgrounds face barriers including financial strain, disrupted laboratory access and cultural exclusion. Peer networks provide vital support when institutional systems are difficult to navigate. To create inclusive learning environments and achieve academic success, educators should blend active, hands‐
