Highly Efficient Upconverted Fluorescence from Coulombically Assembled Ion Pair

open access: yesAdvanced Optical Materials, EarlyView.
A dicationic Os(II) complex paired with two monoanionic fluorophores is designed to enable highly efficient triplet–triplet annihilation upconversion, achieving a remarkable upconverted fluorescence quantum yield of 13% at 785 nm excitation with a record‐low threshold intensity of 5.9 mW cm⁻2, attributed to diffusion‐free acceleration of energy ...

Mesenteric thrombosis: An unusual complication of severe acute pancreatitis—Report of two cases

open access: yesAdvances in Digestive Medicine, EarlyView.
Abstract The incidence of acute pancreatitis is 34 per 100 000 people in the general population and is on the rise. Approximately 15% to 20% of all patients experience severe pancreatitis, with a mortality rate nearing 20%. This condition is often linked to vascular complications, although mesenteric thrombosis is a rare presentation.

Comparison of two extraction methods for ergosterol determination in vegetal feeds [PDF]

open access: yes, 2007
Ergosterol is the principal sterol of fungi in which it plays an essential role in cell membrane and other cellular constituents. This sterol is considered as a good marker of fungal contamination and of mycotoxin production.

A Versatile Disulfide‐Containing Solid‐Support Strategy for 3′‐Modifiers in Oligonucleotides: Introducing Modular Tandem Oligonucleotide Synthesis

open access: yesChemistry – An Asian Journal, EarlyView.
We report a versatile disulfide‐containing linkage to solid support that enables on‐column synthesis of DNA and RNA containing a 3′‐amino or 3′‐phosphate group. This orthogonal solid‐support linker enables a protecting group strategy for the synthesis of oligonucleotides containing 3′‐amino‐2′,3′‐dideoxyribosides directly from commercially available ...

Molecular study of lipids in humic acids by sequential chemical degradation [PDF]

open access: yes, 2009
Lipidy v půdě vykazují poměrně vysokou resistenci k biodegradaci, mohou proto tak zajistit informace o zdrojích organické hmoty a diagenetických procesech. Půdní organická hmota je vysoce heterogenní a vyskytují se v ní různé dynamické systémy.

Sustainable biofuel production from fish processing waste: lipase‐catalyzed hydroesterification of tilapia residual oil

open access: yesBiofuels, Bioproducts and Biorefining, EarlyView.
Abstract Fishing waste and byproducts, whether naturally occurring or from industrial processing, are important sources of high‐value compounds. Fertilizers, biomaterials, cosmetics, biolubricants, and biodiesel are some of the substances that can be obtained from these residues. The objective of this study was to conduct a theoretical and experimental

Separation of gadolinium and europium from chloride media by the solvent extraction technique

open access: yesREM: International Engineering Journal, 2019
Obtaining rare earth elements (REE) is a complicated task, due mainly to the difficulty of separating and purifying them. Solvent extraction is the most widely used technique for separating REE, and the most common extractants used are organophosphorus ...
