( E)-4-[2-(Pyridin-4-yl)vinyl]benzaldehyde, containing both a 4-vinylpyridine and an aldehyde functionality, is utilized to develop new, highly conjugated chalcone compounds and a bis-Schiff base azine compound. The chalcone-containing compounds are further explored for their protonation, methylation and silver(I) coordination chemistry using the pyridine moiety. In parallel, a cyano-containing analogue, ( E)-4-[2-(pyridin-4-yl)vinyl]benzonitrile is also synthesized and studied for its silver(I) coordination chemistry. These new compounds are fully characterized by mass spectrometry, elemental analysis and spectroscopic techniques. The methylated product of ( E)-1-(9-anthryl)-3-{4-[2-(pyridin-4-yl)vinyl]phenyl}prop-2-en-1-one and a silver complex of ( E)-4-[2-(pyridin-4-yl)vinyl]benzonitrile are structurally determined by X-ray crystallography.

“…These coated fabrics have low surface energy, they may exhibit a lotus effect or self-cleaning properties to withstand water and organic liquids [9]. Moisture permeable protective clothing, embedded with a breathable microporous membrane has been developed to provide resistance against liquid chemicals while permitting penetration of air and water vapour [10,11]. Currently, activated carbon-based textiles are extensively used for military and civilian purposes as chemical barrier clothing.…”

Protection is obligatory for the safety of people in certain occupations where they might be exposed to hazardous chemicals. This review provides an overview of chemical protective clothing, along with its necessity during industrial and military operations as well as in response to acts of terror. Moreover, chemical protective or barrier suits are illustrated and explained including their types, selection processes based on chemical hazards, working environments, and various materials available for the fabrication of effective barrier clothing. Additionally, this review elucidates current research gaps, while underscoring the challenges facing recently developed chemical protective clothing, by compiling relevant research onto a single platform. Besides, this review includes and delineates future trends in chemical protective outfits based on electro-spun nano-fibre technology involved in both detection and decomposition of poisonous chemical agents that come in contact with clothing material, and the integration of selectively permeable membrane technology to discriminately block hazardous chemicals.

As the demand for specialized and diversified pressure sensors continues to increase, excellent performance and multi‐applicability have become necessary for pressure sensors. Currently, flexible pressure sensors are primarily utilized in fields such as health monitoring and human‐computer interaction. However, numerous complex extreme environments in reality, including deep sea, corrosive conditions, extreme cold, and high temperatures, urgently require the services of flexible devices. Here, a piezoresistive flexible pressure sensor based on expanded polytetrafluoroethylene/functionalized carbon nanotubes (EPTFE/FCNT) is proposed. Benefiting from the unique fiber‐segment architecture, chemical stability, and strong chemical binding force between EPTFE and FCNT, the fabricated sensor exhibits remarkable sensing capabilities and can be employed in multifarious extreme environments. It demonstrates a sensitivity of 862.28 kPa−1, a response time of 6–7 ms, and a detection limit below 1 Pa. Furthermore, it possesses a pressure resolution of 0.0018% under 111 kPa and can withstand over 10,000 loading and unloading cycles under 1 MPa. Additionally, the EPTFE/FCNT sensor retains its outstanding pressure response and work efficiency in extreme conditions such as an ultra‐low temperature of −80 °C, high temperature (200 °C), acidic and alkaline corrosion, and underwater. These notable attributes enormously broaden the sensors’ real‐world application range.
