Ferroelectricity and piezoelectric energy harvesting of an AMX-type 0D bromobismuthate hybrid with a bulky organic quaternary amine.

Organic-inorganic hybrid ferroelectric compounds of the halobismuthate family have emerged as a focal point of research owing to their reduced toxicity and distinctive optical characteristics. This study presents a novel ammonium hybrid perovskite, [BPMBDMA]·[Bi2Br9], which exhibits both ferro- and piezoelectric properties and crystallizes in the polar noncentrosymmetric 2 space group. The nonlinear optical (NLO) activity of [BPMBDMA]·[Bi2Br9] was corroborated through second harmonic generation measurements evidencing its noncentrosymmetric structure, which was further substantiated by piezoresponse force microscopy analyses.

Molecular genetic characterization of porcine reproductive and respiratory syndrome virus outbreak in Assam, India and neighbouring regions.

Porcine reproductive and respiratory syndrome (PRRS) is a significant swine disease with no effective vaccine due to high viral mutation rates. This study investigates a natural PRRS outbreak through molecular, pathological, and serological analyses. Nineteen affected pigs were clinically examined, and 10 underwent post-mortem examination.

Metabolic interplay between and facilitates polymicrobial biofilm formation and invasive disease.

Biofilms play an important role in the development and pathogenesis of catheter-associated urinary tract infection (CAUTI). and are common CAUTI pathogens that persistently co-colonize the catheterized urinary tract and form biofilms with increased biomass and antibiotic resistance. In this study, we uncover the metabolic interplay that drives biofilm enhancement and examine the contribution to CAUTI severity.

Metal-free small molecule-based piezoelectric energy harvesters.

Organic and metal-free molecules with piezoelectric and ferroelectric properties have gained wide interest for their applications in the domain of mechanical energy harvesting due to their desirable properties such as light weight, thermal stability, mechanical flexibility, feasibility to achieve high Curie temperatures, and ease of synthesis. However, the understanding and design of these materials for piezoelectric energy harvesting applications is still in its early stages. This review paper presents a comprehensive overview of the fundamental characterization of piezoelectricity for a range of organic ferro- and piezoelectric materials and their composites.

Effect of tyrode albumin lactate pyruvate and modified Krebs Ringers broth media on in vitro capacitation of HD-K75 boar spermatozoa at different period of incubation.

In vitro capacitation allows for a greater understanding of the mechanisms underlying fertilization and the development of improved reproductive techniques for improving fertility rates in porcine. Tyrodes albumin lactate pyruvate (TALP) and modified Krebs Ringers Broth (m-KRB) are two medias that are commonly used in research experiments to induce capacitation in boar spermatozoa (Cañón-Beltrán et al., Theriogenology, 198, 2023 and 231; Oberlender et al.
