Article Abstract
This paper reports a superiority of the asymmetric electric field formed in the rectangle microwell array for the electrofusion of splenocytes and myeloma cells with different diameters. The upper substrate with microband electrodes was mounted on the lower substrate with the microwell array. Two electrodes were arranged at the both sides of the microwells on the bottom surface. An attractive force of positive dielectrophoresis was employed to capture splenocytes with smaller diameter and myeloma cells with larger diameter at the right and left of microwells by applying AC electric field. The splenocytes and myeloma cells were fused by the asymmetric electric field that was generated in the microwells by applying DC electric pulse to the bottom electrode at the right side. The asymmetric field could allow to the formation of small openings on the membrane for the fusion of smaller splenocytes by experiencing higher field and the suppression for the disruption of larger myeloma cells by experiencing lower field.

A fundamental question in the field of molecular computation is what computational tasks a biochemical system can carry out. In this work, we focus on the problem of finding the maximum likelihood estimate (MLE) for log-affine models. We revisit a construction due to Gopalkrishnan of a mass-action system with the MLE as its unique positive steady state, which is based on choosing a basis for the kernel of the design matrix of the model.

This study investigated the effects of a low-frequency polarized electric field (LFPEF) on postharvest disease resistance and storage quality of grapes. LFPEF treatment (3 h/d) significantly reduced weight loss, suppressed lesion expansion, and maintained fruit firmness by reinforcing cell wall integrity and enhancing defense-related enzyme activities. Mechanistic analyses indicated that LFPEF activated Ca signaling, promoted calcium accumulation, and upregulated calcium sensor genes, thereby contributing to membrane stabilization.

In recent years, light-controlled ion transport systems have attracted widespread attention, however, the use of photoresponsive materials suffers from rapid carrier recombination, thermal field limitations, and narrow spectral response, which significantly restricts their performance enhancement in osmotic energy conversion. This study innovatively couples "blue energy" (osmotic energy) with "green energy" (solar energy), assembling graphene oxide/molybdenum disulfide/sulfonated cellulose nanocrystal (GO/ MoS/CNC) ion-channel membranes. Under solar irradiation, the energy level difference between MoS and GO effectively suppresses the recombination of photogenerated carriers, generating more active electrons and significantly enhancing the carrier density, thereby improving the current flux and ion selectivity.

Owing to its wide bandgap, LaAlO has garnered extensive attention in the field of high-temperature negative temperature coefficient (NTC) thermistors. However, its poor thermal stability and excessively high B value limit the working temperature range. In this work, introducing O 2p and Ni 3d hybrid energy levels into the bandgap is proposed via Ni doping and inducing stacking faults in the crystal structure to narrow the bandgap and enhance aging performance.

Achieving superior energy storage performance in dielectric materials under low electric fields remains a challenge. Most recent advancements require high fields that limit device applicability. Developing dielectric capacitors with high recoverable energy density (W), efficiency (η), and energy-storage coefficient (W/E) at low/moderate fields is critical for safer, compact, and durable electronics.
