The rapid change of topology is one the most important factors affecting performance routing protocols flying ad hoc networks (FANETs). A scheme suitable for highly dynamic mobile proposed in complex scenarios. In moving nodes sense changes surrounding network periodically, and current scenario confirmed according to perceived result. Furthermore, a protocol selected maintaining performances at high level. concerned metrics are packet delivery ratio, throughput, average end-to-end delay...
Optical vortex beams, endowed with orbital angular momentum (OAM) due to their helical wavefronts, are essential for advancements in optical manipulation, quantum computing, and communication technologies. Existing methods generating beams often struggle issues such as low efficiency, limited scalability, rigid control over beam properties. To address these limitations, we have developed a novel generator utilizing plasmonic metasurface constructed from the antimony telluride (Sb 2 Te 3 )....
The mid-infrared (mid-IR) region, often referred to as the molecular fingerprint encompasses distinctive absorption spectra characteristic of numerous important molecules. However, intrinsically small cross-sections, combined with size mismatch between nanoscale molecules and microscale mid-IR wavelengths, result in inherently weak light-molecule interactions. In this work, we propose a broadband, tunable platform based on plasmonic-enhanced infrared for label-free retrieval fingerprints. By...
Abstract Differential scanning calorimetry and X‐ray diffraction experiments on ß‐nucleated poly(propylene) were made samples crystallized at different temperatures. The crystal perfection was shown to vary with crystallization temperature. observed multiple peaks could be related a ß 1 ‐phase defective inclination of the chains, recrystallized or original 2 more perfect inclination, α‐phase.
An on-chip liquid metal based micro-thermocouple on a reversible bonding technology.
This study presented a convenient method of gathering, splitting, merging, and sorting microdroplets by dynamic pneumatic rails in double-layered microfluidic devices. In these devices, the were placed below droplet channel, with thin elastic polydimethylsiloxane (PDMS) film between them. The PDMS would sag down to rail forming groove pattern at bottom when fluid pressure channel was higher than air channel. could capture flattened droplets guide flow path them due lowered surface energy...
Abstract This work proposes a liquid-metal-based calorimetric micro-flow sensor within polydimethylsiloxane (PDMS) chip. It can measure the flow rate of fluid in microscale channels, with range as low several microliters per minute. in-chip is proposed to solve issue detecting microfluidic systems.
