Journal of the American Oil Chemists' Society, EarlyView.The manuscript confirms and expands on previous reports concerning the presence of unusual conjugated hydroxydienoic fatty acids and acetyl‐TAG in the seed oil of Securidaca longipedunculata. The location of acetate only at sn‐2 of TAG was conclusively shown by high resolution NMR and hydroxy seed fatty acids are characterized.

Three‐dimensional geometric morphometric analysis of diaphragmatic dome motion in COPD patients
The Anatomical Record, EarlyView.Abstract Diaphragmatic dysfunction is a hallmark of chronic obstructive pulmonary disease (COPD), especially in emphysema, where hyperinflation alters diaphragm geometry and impairs inspiratory mechanics. However, quantitative three‐dimensional (3D) assessments of diaphragmatic dome shape and motion across COPD phenotypes are limited.

Combining TLC Separation with MS Detection - A Revival of TLC
Journal of Glycomics & Lipidomics, 2015 It is very likely that every natural scientist has at least heard about thin-layer chromatography (TLC) because its fundamentals are taught in all basic courses of chemistry and biochemistry. TLC is widely used in preparative organic chemistry for a first check of a reaction mixture to monitor how many different products were generated.

Synthesis and Optical Properties of Diboron Complexes of 1,4‐Anthraquinone Derivatives
Chemistry – A European Journal, EarlyView.1,4‐Diboron complexes exhibit near‐infrared fluorescence, in contrast to non‐emissive 1,5‐diboron analogues. Fluorescence quantum yields decrease with increasing electron‐donating substituents, attributed to enhanced nonradiative decay via intramolecular PeT.

Chemistry – A European Journal, EarlyView.A sustainable route to photoresponsive molecular systems is achieved using the bio‐based flavanone (‐)‐isolonchocarpin from Tephrosia vogelii. Through McMurry homocoupling and light‐driven 6‐π‐electrocyclization, an overcrowded alkene and a fluorescent O‐heterocyclic phenanthrene are synthesized.
