PTR-ToF-MS VOC Profiling of Raw and Cooked Gilthead Sea Bream Fillet (): Effect of Rearing System, Season, and Geographical Origin.

This study explores the impact of geographical origin, harvest time, and cooking on the volatile organic compound (VOC) profiles of wild and reared seabream from the Adriatic and Tyrrhenian Seas. A Proton Transfer Reaction-Time of Flight-Mass Spectrometry (PTR-ToF-MS) allowed for VOC profiling with high sensitivity and high throughput. A total of 227 mass peaks were identified.

Porous Halogen-Bonded Frameworks Assembled through Hetero-polytopic Ion Pair Templation.

Halogen-bonding (XB) interactions have been extensively studied in the preparation of crystalline frameworks, yet porous 3D framework materials built on XBs remain elusive. The donor-acceptor interactions are strengthened by use of anionic XB acceptors; however, the requisite charge-balancing cations typically disrupt the framework and occupy potential void space. In this work, we prepare a tetratopic XB donor bearing a crown ether moiety for sodium cation sequestration.

Polytriphenylamine Conjugated Microporous Polymers as Versatile Platforms for Tunable Hydrogen Storage.

Hydrogen (H) as a fuel source presents a promising route toward decarbonization, though challenges in its storage remain significant. This study explores the synthesis and characterization of polytriphenylamine (PTPA) conjugated microporous polymers (CMPs) for H storage. Utilizing a combination of Buchwald-Hartwig (BH) coupling, the Bristol-Xi'an Jiaotong (BXJ) approach, and variations in monomer reactive site stoichiometry, a polymer with specific surface areas in excess of 1150 m g and micropore volume of 0.

Modified Sepiolite Nanoclays in Advanced Composites for Engineering Applications.

Clay-polymer nanocomposites (CPNs) containing a small weight fraction of nanoclay are known to display enhanced mechanical and thermal properties compared to neat polymers. However, the preparation and application of such nanocomposites remain challenging owing to the difficulties in dispersing nanoclays in polymer matrices. This study focuses on two surfactant-modified organophilic sepiolite clays to demonstrate the simplicity of the modification process, as well as on the use of a benzoxazine monomer (i.
