An in silico MS/MS library for automatic annotation of novel FAHFA lipids. [PDF]

, 2015
BackgroundA new lipid class named 'fatty acid esters of hydroxyl fatty acids' (FAHFA) was recently discovered in mammalian adipose tissue and in blood plasma and some FAHFAs were found to be associated with type 2 diabetes.

A Dual‐Emissive DNA‐Templated Silver Nanocluster with Near‐Infrared I and II Emission

Advanced Optical Materials, Volume 13, Issue 8, March 13, 2025.
This study presents a dual‐emissive DNA‐stabilized silver nanocluster with a nanosecond‐lived NIR‐I emission band and a microsecond‐lived NIR‐II emission band. Mass spectrometry establishes that the nanocluster has molecular formula (DNA)2[Ag17]11+. DNA sequence variations reveal critical nucleobases for stabilization, and modifications at the DNA 5 ...

Water‐Mediated 1,7‐Palladium Aryl‐to‐Aryl Migration in an Unusual Aryne Trimerization Enables the Synthesis of Multihelicenes with Profoundly Hindered Stereogenic Axes

Advanced Synthesis &Catalysis, EarlyView.
In the presence of a Pd0 catalyst, large π‐extended arynes trimerize in an unusual manner to forge extremely compact and strained chiral benzenoids. This new trimerization reaction involves a 1,7‐Pd isomerization, a rare and poorly understood process that is elucidated.

Naphthalimide Derivatives as Film‐Based Fluorescent Sensors for Rapid Detection of Illicit Drugs

Advanced Sensor Research, EarlyView.
Four novel 1,8‐naphthalimide (NI) derivatives for the detection of illicit drugs with different substituents at the 4‐position are reported. Their contrasting fluorescence responses enables five illicit drugs to be distinguished from interferents with a mean classification accuracy of 81%.

Single-photon absorption of isolated collagen mimetic peptides and triple-helix models in the VUV-X energy range [PDF]

, 2017
Cartilage and tendons owe their special mechanical properties to the fibrous collagen structure. These strong fibrils are aggregates of a sub-unit consisting of three collagen proteins wound around each other in a triple helix.
