To investigate the differences in key volatile components among different types of baijiu, this study utilized - nose, HS-SPME-GC-MS/MS, and HS-GC-IMS to identify key volatile compounds in four baijiu samples: Sauce-flavor (SAF), Thick Sauce-flavor (TSF), Strong-flavor (STF), and Light-flavor (LF). baijiu total of 35, 29, 8, and 12 key volatile components were identified in SAF, TSF, STF, and LF samples, respectively. Based on these findings, the study explored the differences and correlations in aroma profiles among different baijiu aroma types. The results provide valuable insights for baijiu flavor differentiation and product optimization while also offering a theoretical foundation for in-depth research on baijiu aroma and the development of new products.

Polyploidy is an important driver of the evolution and diversification of flowering plants. Several studies have shown that established polyploids differ from diploids in floral morphological traits and that polyploidization directly affects these traits. However, for floral scent, which is key to many plant-pollinator interactions, only a few studies have quantified differences between established cytotypes, and the direct effects of polyploidization on floral scent are not yet known.

Jasmine tea, a further processing tea made by scenting green, black, oolong, or other tea with jasmine flowers, is widely appreciated worldwide for its fragrant aroma, refreshing taste, and beneficial health effects. The production of jasmine tea is a meticulous and complex process that involves chemical reactions, physical adsorption, and flavor interaction effects at the sensory level between jasmine and tea. This paper provides a comprehensive review of the research on the processing technology, characteristic aroma formation, nonvolatile compounds, and health benefits of jasmine tea.

Neuromorphic Visual Devices hold considerable promise for integration into neuromorphic vision systems that combine sensing, memory, and computing. This potential arises from their synergistic benefits in optical signal detection and neuro-inspired computational processes. However, current devices face challenges such as insufficient light/dark resistance ratios, mismatched transient photo-response, and volatile retention characteristics, limiting their adaptability to complex artificial vision systems.

Naomaohu lignite (NL) from Hami, Xinjiang, was ultrasonically extracted with a mixed solvent of CS and acetone (in equal volumes) to obtain the extract residue (ER). The ER was then separated based on density differences with CCl to yield the corresponding light residue (NL-L). The composition and structural characteristics of the light residue were characterized by proximate, ultimate, infrared, and thermogravimetric analyses (TG-DTG).

Background: Volatile anesthetics are gaining recognition for their benefits in long-term sedation of mechanically ventilated patients with bacterial pneumonia and acute respiratory distress syndrome. In addition to their sedative role, they also exhibit anti-bacterial and anti-inflammatory properties, though the mechanisms behind these effects remain only partially understood. In vitro studies examining the prolonged impact of volatile anesthetics on bacterial growth, inflammatory cytokine response, and surfactant proteins - key to maintaining lung homeostasis - are still lacking.
