Volatile components from Exocarpium Citri Grandis (ECG) were, respectively, extracted by three methods, that is, steam distillation (SD), headspace solid-phase microextraction (HS-SPME), and solvent extraction (SE). A total of 81 compounds were identified by gas chromatography-mass spectrometry including 77 (SD), 56 (HS-SPME), and 48 (SE) compounds, respectively. Despite of the extraction metho...

Volatile organic compounds are important flavor components of finished wines. In addition to winemaking practices, which shape wine quality, cultivation of the grape berries in the vineyard each season affects the production of volatile organic compounds as well as other chemical components that ultimately contribute to our perception of flavor in finished wines. By studying how berry flavor co...

The existence of two basic levels of storage (fast/volatile and slow/non-volatile) has been a long-standing premise of most computer systems, influencing the design of OS components, including file systems, virtual memory, scheduling, execution models, and even their APIs. Emerging resistive memory technologies – such as phase-change memory (PCM) and memristors – have the potential to provide l...
