Assessment of the Oxidative State of Thermally Treated Sunflower Oil After Regeneration with Molecular Sieves

open access: yesEngineering Proceedings
Edible oils undergo undesirable changes over time or during thermal treatment due to enzymatic, microbial, and chemical processes, leading to spoilage. In this study, the oxidative state of sunflower oil was assessed by determining the peroxide value (PV)

Small RNA pathways in mammalian oocytes

open access: yesFEBS 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 ...

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

open access: yesFEBS 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‐

Preparation of gasified ash-based zeolite molecular sieve PEI modification and CO2 adsorption performance

open access: yesMeitan xuebao
Aiming at the problems of bulk solid waste accumulation and environmental pollution caused by the large output and low utilization rate of coal-to-oil gasification ash, and combining with the strategic goal of "double-carbon", the idea of combining ...

MagmaFlow: A desktop platform for artificial intelligence‐driven expression analysis

open access: yesFEBS Open Bio, EarlyView.
MagmaFlow is a free, no‐code platform for gene expression analysis. It generates interactive volcano plots, links genes to literature, pathways, and diseases, prioritizes candidates using millions of publications, identifies affected biological processes, builds network diagrams, and exports publication‐ready figures and reports for macOS and Windows ...

Structural characterization of zeolitic catalysts in non-ambient conditions by X-ray and neutron diffraction [PDF]

open access: yes, 2009
This PhD thesis strives to give an exhaustive characterization of the behaviour of zeolites in nonambient conditions. Zeolites presents a lot of peculiar characteristics, such as shape selectivity, high thermal stability, but the most important is ...

Preparation and structure characterization of nanospherical MCM- 41 molecular sieves

open access: yes上海师范大学学报. 自然科学版, 2013
Nanospherical MCM-41 molecular sieves have been synthesized by using hexadecyl trimethyl ammonium bromide (CTAB) as templates and tetraethyl orthosilicate (TEOS) as silicon sources.

Evolution‐guided yeast complementation reveals functional differences in human PSPH variants

open access: yesFEBS Open Bio, EarlyView.
Ancient genomes can help guide which human genetic variants are tested experimentally. This study applies that idea to PSPH, a gene involved in serine biosynthesis, and uses high‐throughput yeast complementation to compare variant function. The findings reveal measurable differences among selected alleles and illustrate the value of evolution‐guided ...

Effect of water on the ionothermal synthesis of molecular sieves

open access: yes, 2008
AIPO(4)-11 adn AIPO(4)-5 molecular sieves are ionothermally prepared without addition of water by using anhydrous starting materials, such as NH4H2PO4, pseudodoehmite (ALOOH), and NH4F. The synthesis appears to be an autocatalytic process.

Adsorptive Distillation Using Molecular Sieves and Low-Cost Biobased Adsorbents for the Break-up of the Isopropanol–Water Azeotrope

open access: yesAdsorption Science & Technology, 2003
The separation of isopropanol from aqueous vapours near the azeotropic composition was investigated using fixed beds packed with type A molecular sieves and biobased adsorbents.
