Article Abstract

In this work, a self-powered system based on a triboelectric-electromagnetic hybrid pipeline energy harvesting module is demonstrated. Rabbit fur and poly tetra fluoroethylene (PTFE) are used as triboelectric electrodes to fabricate disk-type soft-contact triboelectric nanogenerators (TENGs) instead of traditional direct-contact TENGs to collect the mechanical energy of water flow and convert it into electrical energy. This design has a stable electrical output and gives an improved durability. Its simple fabrication process enables excellent potential for practical applications in industry. In addition, the hybridization of electromagnetic generator module and TENGs module to form a triboelectric-electromagnetic hybrid nanogenerator (TEHNG) can improve the electrical output performance, especially the current output. TEHNG cannot only power small electronic devices, such as lighting systems, but also collect independent fluid energy and monitor data signals simultaneously in harsh environments, such as fluid energy harvesting in industrial production pipelines and temperature and humidity in fluid environments. This work provides an efficient strategy to harvest multiple energies simultaneously, significantly increasing the yield and promoting the application of TENGs in engineering.

How SNARE proteins generate force to fuse membranes.

Biophys J

January 2025

Department of Chemical Engineering, Columbia University, New York, NY 10027. Electronic address:

Membrane fusion is central to fundamental cellular processes such as exocytosis, when an intracellular machinery fuses membrane-enclosed vesicles to the plasma membrane for contents release. The core machinery components are the SNARE proteins. SNARE complexation pulls the membranes together, but the fusion mechanism remains unclear.

This research proposes an all-metal metamaterial-based absorber with a novel geometry capable of refractive index sensing in the terahertz (THz) range. The structure consists of four concentric diamond-shaped gold resonators on the top of a gold metal plate; the resonators increase in height by 2 µm moving from the outer to the inner resonators, making the design distinctive. This novel configuration has played a very significant role in achieving multiple ultra-narrow resonant absorption peaks that produce very high sensitivity when employed as a refractive index sensor.

This research presents an innovative polarization-insensitive metasurface (MS) harvester designed for energy harvesting applications at 5 GHz, capable of operating efficiently over wide reception angles. The proposed MS features a novel wheel-shaped resonator array whose symmetrical structure ensures insensitivity to the polarization of incident electromagnetic (EM) waves, enabling efficient energy absorption and minimizing reflections. Unlike conventional designs, the metasurface achieves near-unity harvesting efficiency, exceeds 94% under normal incidence, and maintains superior performance across various incident angles for TE and TM polarizations.
