Multilayer thin films composed of dielectric BaCaZrTiO (BCZT) and oxygen-deficient BCZT (BCZT-OD) were fabricated on (001)-oriented NSTO substrates using the pulsed laser deposition (PLD) technique. Unlike conventional approaches to energy storage capacitors, which primarily focus on compositional or structural modifications, this study explored the influence of the layer sequence and periodicity. The interface between the NSTO substrate and the BCZT-OD layer forms a Schottky barrier, resulting in electric field redistribution across the sublayers of the BCZT/BCZT-OD//(1P) thin film.

Silk fibroin (SF) hydrogel has been proven to have excellent applications in the field of pressure sensors, but its sensing performance still needs improvement. A flexible hydrogel prepared from natural macromolecular materials was developed, and lignin nanoparticles (LNPs) were introduced during the preparation of the SF hydrogel. When LNPs account for 3% of SF, the sensing unit of the SF-LNPs hydrogel exhibits high stress sensitivity (1.

The direct power control (DPC) algorithm is one of the most popular linear techniques used to implement notable controllers, known for their simplicity and fast dynamic response. However, this approach has drawbacks that cause a decrease in the current quality and disturbances in the network. Therefore, this experimental work presents a simple and efficient solution that uses a proportional-integral regulator based on a genetic algorithm to regulate the power quality.

Glycosylation, the intricate process of adding carbohydrate motifs to proteins, lipids, and exosomes on the cell surface, is crucial for both physiological and pathological mechanisms. Alterations in glycans significantly affect cancer cell metastasis by mediating cell-cell and cell-matrix interactions. The subtle changes in glycosylation during malignant transformations highlight the importance of analyzing cell and exosome surface glycosylation for prognostic and early treatment strategies in cancer.
