SAPONIFICAÇÃO ASSISTIDA POR MICRO-ONDAS NA EXTRAÇÃO DE DITERPENOS EM CAFÉ ARÁBICA TORRADO
Química NovaThe extraction of kahweol and cafestol involves saponification reaction. This step is important for the efficiency of the extraction as the diterpenes are susceptible to structural changes during hydrolysis. The microwave-assisted saponification has been

Seasonal Changes in Marine Archaeal Tetraether Lipid Export Depth Linked to Net Primary Productivity
Paleoceanography and Paleoclimatology, Volume 41, Issue 2, February 2026.Abstract Marine ammonia oxidizing archaea (AOA) produce isoprenoid glycerol dibiphytanyl glycerol tetraethers (GDGTs) which form the basis of seawater temperature proxy TEX86. Although most studies use TEX86 for sea surface temperature (SST) reconstructions, maximum GDGT production occurs at and below the nitracline. Moreover, sedimentary GDGT‐2/GDGT‐3

Journal of the Science of Food and Agriculture, Volume 106, Issue 2, Page 1299-1313, 30 January 2026.Abstract Background Persimmon (Diospyros kaki Thunb.) byproducts are a remarkable source of bioactive compounds, particularly carotenoids. Several studies suggest that carotenoids have beneficial effects in prevention of a large number of diseases. This study aims to highlight the effects of a persimmon carotenoid extract (PSCE) rich in β‐cryptoxanthin

Thiophene Derivatives as Versatile Precursors for (Hetero)Arene and Natural Product Synthesis
Angewandte Chemie International Edition, Volume 65, Issue 5, 28 January 2026.Hidden but Powerful: Thiophenes and their saturated analogues have been demonstrated to be versatile C4‐building blocks that can be rapidly applied to natural product synthesis and the construction of functionalized (hetero)arenes. This minireview aims to provide a concise overview of the strategies and implementations of these sulfur‐containing ...

Multistate Azobenzene–Norbornadiene Photoswitches for Molecular Solar Thermal Energy Storage
Chemistry – A European Journal, Volume 32, Issue 2, 9 January 2026.Systems consisting of two different photoswitches (azobenzene and norbornadiene) are presented, which can be switched by light, store energy, and release it again. The combination of the switching units leads to synergistic effects. ABSTRACT The combination of two photochromic molecules into a multimodal photoswitch offers the potential to generate new
