Recently, biodegradable packaging materials have received significant prominence in the food sector. Herein, chrysanthemum leaves extract (CLE), integrated sodium alginate (SA) and polyvinyl alcohol (PVA) active films were prepared and their physicochemical and multifunctional properties were evaluated for use in green chili packaging. FTIR and SEM results confirmed favorable interaction and uniform dispersion of CLE in the SA/PVA blend film. Addition of CLE to the SA/PVA matrix considerably lowered surface wettability (∼61 %), water solubility (∼28 %), moisture-binding (∼27 %), water vapor transmission and oxygen permeability (∼28 %). CLE-loaded active film demonstrated higher tensile strength (29.06 ± 0.46 MPa), UV light barrier capabilities and significant antimicrobial activity against foodborne pathogens. Additionally, it had an adequate antioxidant capacity of (∼46 %) compared to the control film without CLE. In the study of green chili packaging, the active film containing a more significant amount of CLE limited the weight loss, suppressed microbial growth and retained the polyphenolic and chlorophyll content of the chili. Compared to polyethylene (PE), the fabricated active film displayed a far better packaging capability and extended the shelf life of green chili for up to 10 days. Hence, the fabricated active films were suitable for biodegradable packaging applications.

While amorphous indium gallium zinc oxide (α-IGZO) thin film transistors (TFTs) are practical alternatives to silicon-based TFTs, their field-effect mobility (∼50 cm/(V s), depending on deposition conditions) remains insufficient to meet the growing demands of high-resolution active-matrix organic light-emitting diode (AMOLED) displays. The need for high-performance oxide TFTs with mobility ≥100 cm/(V s) has become critical to meet the evolving display industry's requirements. This study explored the development of high-mobility hexagonal homologous compound (HC) indium zinc tin oxide (IZTO) TFTs as an alternative to α-IGZO TFTs.

Enhancing the performance of organic solar cells (OSCs) is essential for achieving sustainability in energy production. This study presents an innovative strategy that involves fine-tuning the thickness of the bulk heterojunction (BHJ) photoactive layer at the nanoscale to improve efficiency. The organic blend D18:L8-BO is utilized to capture a wide range of photons while addressing the challenge of minimizing optical losses from low-energy photons.

Enzymatic hydrolysis of polyethylene terephthalate (PET) is a promising technology for advancing a circular PET economy. Several PET-degrading α/β hydrolases have been identified, but the full potential of this enzyme family to catalyze PET hydrolysis remains largely unexplored. To address this, sequence similarity networks were employed to investigate the α/β hydrolase fold-5 subfamily (IPR029059) for new PETases.

Through-space charge transfer (TSCT) rather than the commonly postulated metal-to-ligand charge transfer (MLCT) process was proposed in getting the lowest lying excited state of newly designed Ir(III) blue phosphors. Accordingly, two benzo[d]imidazolylidene pro-chelates L12H2+ and L13H2+, one with two cyano groups at the peri-benzo and N-aryl pendent and the other with its peri-cyano group being replaced with methyl substituent, were employed in syntheses of Ir(III) complexes f-ct12b,c and f-ct13b,c. Notably, complexes f-ct12b,c exhibited the traditional MLCT process, while f-ct13b,c were dominated by the TSCT transition, resulting in a smaller S1-T1 energy gap ΔEST.
