A highly efficient protective membrane based on PVDF-HFP/LiF for protecting an LATP solid-state electrolyte from lithium metal anodes.
The growing energy demands of the industrial world have driven advancements in green technologies. Microbial fuel cells (MFCs), which harness power from microorganisms, show promise for extraction wastewater and sludge. However, challenges remain improving output sustaining performance under high-charge conditions. Incorporating nanomaterials into 3D structures offers potential solutions, including miniaturized designs. This study introduces nickel silicide nanowires as anode materials MFCs....
In this report, the fabrication of vertically aligned carbon nanotube nanoelectrode array (VACNT-NEA) by photolithography method is presented. Electrochemical impedance spectroscopy as well cyclic voltammetry was performed to characterize arrays with respect different diffusion regimes. The fabricated illustrated sigmoidal voltammogram steady state current dominated radial diffusion. VACNT-NEA and high density VACNTs were employed electrochemical glutamate biosensors. Glutamate dehydrogenase...
A novel vertically aligned carbon nanotube based electrical cell impedance sensing biosensor (CNT-ECIS) was demonstrated for the first time as a more rapid, sensitive and specific device detection of cancer cells. This is on fast entrapment cells arrays leads to mechanical interactions between CNT tips entrapped membranes, changing biosensor. CNT-ECIS fabricated through photolithography process Ni/SiO2/Si layers. Carbon have been grown 9 nm thick patterned Ni microelectrodes by DC-PECVD....
Bioinspired materials can mimic the stem cell environment and modulate differentiation proliferation. In this study, biomimetic micro/nanoenvironments were fabricated by cell-imprinted substrates based on mature human keratinocyte morphological templates. The data obtained from atomic force microscopy field emission scanning electron revealed that keratinocyte-cell-imprinted poly(dimethylsiloxane) casting procedure could imitate surface morphology of plasma membrane, ranging nanoscale to...
In this study, flakes of molybdenum disulfide (MoS2) with controlled size and thickness are prepared through sequential solvent exchange method by sonication in dimethylformamide (DMF) N-methyl-2-pyrrolidone (NMP) solvents. While NMP acts more effectively reducing the flakes, DMF shows better potential conserving lateral nanosheets. The distribution nanoflakes as a function time verifies that extended results dramatic drop dimension exfoliated flakes. This technique leads to formation...
We report the use of vertically aligned carbon nanotubes (VACNTs) as electrical endoscopes (biosensors) for cancer metastatic diagnosis at single-cell resolution.
