Abstract Simultaneously generating various motion modes with high strains in piezoelectric devices is highly desired for high-technology fields to achieve multi-functionalities. However, traditional approach designing multi-degrees-of-freedom systems bond together several multilayer stacks, which generally leads cumbersome and complicated structures. Here, we proposed a transparent piezo metasurface types of wide frequency range. As an example, designed ten-unit metasurface, can produce ( ε...
Piezoelectric devices based on a variety of vibration modes are widely utilized in high-tech fields to make conversion between mechanical and electrical energies. The excitation single or coupled piezoelectric is mainly related the structure property materials. However, for generally used materials, e.g., lead zirconate titanate ceramics, most coefficients matrix equal zero, resulting many cannot be excited, which hinders design devices. In this work, an orderly stacked with strain units...

This study aimed to predict the optimal carbon source for higher production of exopolysaccharides (EPS) by Lactobacillus paracasei TD 062, and evaluate effect this on monosaccharide composition EPS. We evaluated EPS capacity 20 strains L. under same conditions. further investigated which showed highest EPS-producing activity (0.609 g/L), examining associated biosynthesis pathways Genomics revealed that fructose, mannose, trehalose, glucose, galactose, lactose were sources 062 could use...
Cronobacter sakazakii (C. sakazakii) is a food-borne pathogen that can be spread by powdered infant formula (PIF) to cause illness in infants. Bacteriophages (phages) are an effective potential strategy control pathogens. Phage JK004 which isolated from the native environment of C. was novel virulent phage with short latent period and large burst size. had tolerance heat, pH osmotic-stress. The did not contain known virulence, transduction or antibiotic resistance genes, indicating safe...
Low driving voltage is important for miniaturization and untethered service of millirobots made piezoelectric materials. In this research, we designed a bio-inspired bimorph-structured millirobot with transparent relaxor ferroelectric crystal. Due to the ultrahigh piezoelectricity crystals optimized bimorph-based structure, shows maximum moving speed up 9.22 b s−1 (body length per second) at 100 V, while minimum initial movement can be as low 3 which more than two orders magnitude smaller...
Electric-field control of magnetism is one the most promising routes for developing energy-efficient magnetoresistive random access memory and spin-logic devices.
