Summary: This study extensively examines the relationship between contact overlap, protective effect, electric field, and ESD resilience in bottom-gate bottom-contact pentacene organic field-effect transistor (OFET) devices. The research shows a significant increase in tolerance with negative contact overlaps, and a slight decrease with more positive overlaps. Careful consideration should be given to negative overlap lengths when designing OFET devices to balance decreased performance and increased ESD resilience.

Summary: This paper investigates fluid-solid interaction in an electrostatic microvalve to control flow rate. By imposing a DC voltage on a double clamped microbeam in a capacitive system, the microbeam is deflected, changing the boundary conditions of the fluid domain. The Navier-Stokes and Euler-Bernoulli equations are solved simultaneously in each step of increasing voltage. A mapping approach is used to overcome difficulties in the finite element solution for moving boundaries in the fluid domain. Silicon and dielectric elastomer (DE) are compared as materials for the microbeam, and the results show that DE can be an attractive candidate for microvalve due to its lower required applied voltage for achieving a certain flow rate. The findings of this study are also valuable for modeling fluid-solid interaction problems with moving boundaries, especially in microvalve design applications.

Summary: Nowadays, neuromorphic systems based on memristors have potential for hardware realization of efficient artificial intelligence systems. However, their performance is strongly affected by the unavoidable variations in memristive devices. Reservoir computing and spiking neuromorphic systems have been proposed as valuable options to address this problem. In this study, a fully organic system is created by combining both approaches, using volatile polyaniline memristive devices for the reservoir layer and nonvolatile parylene memristors for the SNS readout layer. This combination simplifies the training procedure and provides greater robustness to device variability.

Summary: Achieving a positive total pressure gain (PG) is crucial for the application of rotating detonation in aerospace propulsion systems. This study conducts a theoretical analysis on the PG of a rotating detonation system and emphasizes the impact of the reverse oblique shock wave (ROSW) on system performance.

Summary: Two-dimensional (2D) cell culture lacks cell-cell and cell-extracellular matrix interactions, while three-dimensional (3D) cell culture methods enable equal transportation and mimic the in vivo conditions. Spheroids, self-assembled 3D cell aggregates, closely mimic the cell microenvironment and have important applications in medical and clinical research. Microfluidic methods provide rapid and precise fabrication of spheroids and allow for mimicking of the microenvironment-like in vivo conditions.

Summary: This study proposes a microfluidic channel design for efficient enrichment of CTCs from blood, independent of epitopes. Compared to existing designs, the design with hydrofoil-shaped pillars demonstrates higher recovery rates and slightly lower white blood cell depletion rate. The results show that the recovery rate is influenced by the size and deformability variation of the different cell lines. The analysis confirms that the microfluidic chip process does not affect cell viability.

Summary: With the development of Lab on a chip technology, fluid management using dispersed droplets has become an important approach. Electrowetting on dielectric (EWOD) is one method for droplet actuation, but it requires prior definition of droplet positions. Optoelectrowetting (OEW) goes further by allowing changes in electrical parameters through impinging light spots, without the need for predefined droplet positions. This study re-evaluates the key parameters of OEW and explores their effects on droplet actuation using numerical optimization methods.
