Oxalate-silica gel thin-layer system for free 2-hydroxy fatty acids and for fatty acyl coenzyme A

open access: yesJournal of Lipid Research, 1972
The 2-hydroxy fatty acids tend to yield streaks in thin-layer chromatography on silica gel plates. If potassium oxalate is included with binder-free silica gel, good spots are obtained.

Semiconducting Polymers Post‐Functionalized With Ureido‐Pyrimidinone for Robust Stretchable Transistors

open access: yesAdvanced Functional Materials, EarlyView.
The design of intrinsically robust stretchable semiconducting polymers was achieved through OTBS‐mediated post‐functionalization of PDPP2T side chains with UPy units, generating dual hydrogen‐bonding motifs comprising weaker urethane linkages and strong quadruple UPy interactions along the long alkyl side chain, which is crucial for achieving desirable

Distribution of fatty acids in triacylglycerols from ungrafted Desi Mango (Mangifera indica) kernel lipids

open access: yesJournal of Saudi Chemical Society, 2010
The lipids of ungrafted ‘Desi’ mango (Mangifera indica) kernel were extracted with chloroform/methanol, purified and triacylglycerols (82.6%) were separated by thin layer chromatography (TLC). The pure triglycerides are fractionated into five bands by 25%

Sulfur‐Free Ultrahigh‐Refractive‐Index Polymers Enabled by Densely Packed Oxygen‐Bridged Dibenzofuran‐Cardo Architectures

open access: yesAdvanced Functional Materials, EarlyView.
A new class of sulfur‐free, oxygen‐bridged dibenzofuran‐based polymers is developed for ultrahigh‐refractive‐index applications. The rigid π‐extended architecture and enhanced molecular polarizability enable exceptional optical performance, combining refractive indices up to 1.848 with high Abbe numbers and full visible transparency. This work offers a

Mono‐Material Polydisulfides for Pressure Sensitive Adhesive Tapes With Closed‐Loop Recyclability

open access: yesAdvanced Functional Materials, EarlyView.
A high‐performance pressure‐sensitive adhesive (PSA) tape is developed where both the adhesive layer and plastic backing layer can be recycled back to monomer in a closed‐loop cycle. Both layers of the tape are composed of analogous polydisulfide copolymers using only two unique monomers, thus giving it a mono‐material design and enabling recycling of ...

Chemiluminescence detection of gangliosides by thin-layer chromatography.

open access: yesJournal of Lipid Research, 1995
We describe a method for the detection of gangliosides on thin-layer chromatography plates using enhanced chemiluminescence. In contrast to previously published colorimetric techniques, the use of chemiluminescence of detect antibody binding to ...

Electrochemical Pathways for Nitrate Conversion to Ammonia: From Environmental Challenges to Ammonia Economy

open access: yesAdvanced Functional Materials, EarlyView.
This perspective presents recent advances in electrocatalytic nitrate reduction, focusing on reaction mechanisms, catalyst design, and electrolyzer configurations. Key challenges in selectivity, stability, and practical wastewater treatment are highlighted, while future directions for advancing sustainable ammonia synthesis and nitrate remediation are ...

Preparative thin-layer and column chromatography of prostaglandins

open access: yesJournal of Lipid Research, 1969
Analytical and preparative chromatographic methods for monounsaturated prostaglandins are described. The systems were developed specifically for separation of the various hydroxy epimers of prostaglandin E1 and F1 but also offer superior separations for ...
