Carbon–cement supercapacitors as a scalable bulk energy storage solution
Published 2024“…Texture analysis reveals that the hydration reactions of cement in the presence of carbon generate a fractal-like electron-conducting carbon network that permeates the load-bearing cement-based matrix. The energy storage capacity of this space-filling carbon black network of the high specific surface area accessible to charge storage is shown to be an intensive quantity, whereas the high-rate capability of the carbon-cement electrodes exhibits self-similarity due to the hydration porosity available for charge transport. …”

SARS-CoV-2 evolution during treatment of chronic infection
Published 2021“…In vitro, the spike double mutant bearing both ΔH69/ΔV70 and D796H conferred modestly decreased sensitivity to convalescent plasma, while maintaining infectivity levels that were similar to the wild-type virus.The spike substitution mutant D796H appeared to be the main contributor to the decreased susceptibility to neutralizing antibodies, but this mutation resulted in an infectivity defect. …”

Response of geostationary communications satellite solid-state power amplifiers to high-energy electron fluence
Published 2017“…We also find that the accumulated voltages reached are high enough to compromise components in the amplifier system, for example, the direct current (DC) blocking capacitor. An electron beam test using a representative coaxial cable terminated in a blocking capacitor showed that discharges could occur with peak voltages and energies sufficient to damage active RF semiconductor devices.…”

Opto-mechatronics instrumentation of a specialty optical fiber based optogenetic probe
Published 2019“…The galvanometric mirrors in the conventional targeted neuronal stimulation studies were replaced by the Spatial Light Modulators (SLM) in the state of the art optogenetics system due to its superior beam modulation options and response time. However, most of the SLM integrated with the optogenetic systems using coherent fiber bundle are the reflective type which suffers from a major drawback of complex optical configuration. …”
