Sensitivity Threshold for Selected Aromas and Defects in Casual Wine Consumers

Journal of Sensory Studies, Volume 41, Issue 2, April 2026.
ABSTRACT Wine aromas and faults are caused by chemical compounds impacting wine quality that can originate from viticulture, vinification, bottling, or aging. Wine professionals are highly trained to recognize and assess quality indicators including characteristic aromas and faults/defects.

Effect of fermentation region on the volatile compounds and sensory characteristics of soy sauce mash

Journal of the Science of Food and Agriculture, Volume 106, Issue 4, Page 2190-2199, 15 March 2026.
Abstract BACKGROUND Regional environmental conditions, particularly temperature, significantly affect the fermentation characteristics of traditional fermented foods. This study investigated how regional variations influence the volatile aroma compounds and sensory aroma attributes of soy sauce mash fermented in different locations in Korea.

Schnelle RASER‐MRT

Angewandte Chemie, Volume 138, Issue 10, 2 March 2026.
Schnelle RASER‐MRT ermöglicht Bildgebung ohne RF‐Anregung. Stattdessen wird eine Populationsinversion der Kernspins durch SABRE‐Hyperpolarisation erzeugt, die eine Selbstanregung durch RASER ermöglicht. Wenn die gewünschte transversale Magnetisierung aufgebaut ist, wird herkömmliche EPI‐Kodierung ausgelöst, um das Bild aufzuzeichnen.

Rapid RASER MRI

Angewandte Chemie International Edition, Volume 65, Issue 10, 2 March 2026.
Rapid RASER MRI allows for image acquisition without RF excitation. Instead, a population inversion on the nuclear spins is generated by SABRE hyperpolarization, which allows for self‐excitation through the RASER approach. When the desired transverse magnetization is built‐up, conventional EPI encoding is triggered to record the image.

[1,2,5]Thiadiazolo[3,4-b]pyrazine-5,6(4H,7H)-dione

Molbank
Fused 1,2,5-chalcogenadiazoles are often used as biologically active compounds and organic optovoltaic materials. [1,2,5]Thiadiazolo[3,4-b]pyrazines are much less studied due to difficulties in their preparation. In this communication, [1,2,5]thiadiazolo[

High‐Performance Flexible Near‐Infrared Organic Light‐Emitting Diodes with a Heterogeneous Alloy Semitransparent Electrode

Advanced Materials, Volume 38, Issue 17, 20 March 2026.
This study presents a micro‐structured magnesium‐bismuth alloy electrode that enhances flexible NIR OLEDs. The electrode provides 40% broadband transmittance (400–1600 nm) and boosts light outcoupling efficiency (42.3%) and photoluminescence quantum yield (71.8%) through the Purcell effect in optical microcavities.
