Fluoropolymer alone, as an alternative to lead-based piezoelectric materials, has shown multiple challenges to develop useful sensors for solving real-world problems such as photoacoustic, ultrasound pulse echo, and other non-destructive testing. This work demonstrates the fabrication of high frequency and wide bandwidth transducers with fluoropolymer and highly polarizing cubic single crystal Barium titanate (BaTiO) ceramic composite for high resolution in-vivo photo-acoustic and ultrasound imaging. For transducer fabrication, a customized bio-compatible nanocomposite sensor film of PVDF-TrFE (Polyvinylidene fluoride trifluoroethylene)/BaTiO (BTO) is synthesized by drop and dry in heating-cum-electro-poling system for advancing polarization, crystallinity, and higher charge generation.

Sluggish redox kinetics and dendrite growth perplex the fulfillment of efficient electrochemistry in lithium-sulfur (Li-S) batteries. The complicated sulfur phase transformation and sulfur/lithium diversity kinetics necessitate an all-inclusive approach in catalyst design. Herein, a compatible mediator with nanoscale-asymmetric-size configuration by integrating Co single atoms and defective CoTe (Co-CoTe@NHCF) is elaborately developed for regulating sulfur/lithium electrochemistry synchronously.

Pathogen nucleic acid detection technology based on isothermal amplification and CRISPR/Cas12a system offers advantages in terms of high sensitivity, high specificity, and rapidity. However, this method has not been widely applied because of its shortcomings in utilizing conventional instruments, which cannot satisfy the requirements for Point of Care Testing (POCT), such as integration, convenience, and miniaturization. In this study, we developed an integrated lift-heater centrifugal microfluidic platform (Lift-CM) to automate the processes of isothermal amplification and CRISPR/Cas12a detection.

Fungal lipases are the leading industrial biocatalyst due to their broad applications, but high cost limits their commercial usage. The low-cost agri-residues substrates can reduce the cost of lipase production. However, the compatibility of agri-residue with fungal species, recovery process of lipase and stability of the enzyme are crucial steps.

The growing demand for environmentally friendly semiconductors that can be tailored and developed easily is compelling researchers and technologists to design inherently bio-compatible, self-assembling nanostructures with tunable semiconducting characteristics. Peptide-based bioinspired materials exhibit a variety of supramolecular morphologies and have the potential to function as organic semiconductors. Such biologically or naturally derived peptides with intrinsic semiconducting characteristics create new opportunities for sustainable biomolecule-based optoelectronics devices.
