Nano-Carbon Electrodes for Thermal Energy Harvesting

Abstract

Thermogalvanic cells are capable of converting waste heat (generated as a by-product of almost all human activity) to electricity. These devices may alleviate the problems associated with the use of fossil fuels to meet the world's current demand for energy. This review discusses the developments in thermogalvanic systems attained through the use of nano-carbons as the electrode materials. Advances in cell design and electrode configuration that improve performance of these thermo converters and make them applicable in a variety of environments are also summarized. It is the aim of this review to act as a channel for further developments in thermogalvanic cell design and electrode engineering.

Protective effect of selenium against cisplatin-induced nasopharyngeal cancer in male albino rats

“…ROS play a vital role in facilitating signal transduction processes within the intracellular region (10). The fluorescent probe, DCFH-DA, determined the intracellular ROS generation.…”

“…Control cells were incubated with growth medium only. The cells were examined with a fluorescence microscope (10) (Axiovert 2000; Carl Zeiss AG, Oberkochen, Germany).…”

“…Cells were stained with EB and AO stains. The cells were viewed immediately under a CLS microscope (1X81 R Motorized Inverted Microscope; Olympus Corporation, Tokyo, Japan) (10). …”

“…The cells were incubated with 5 µM of DCFH-DA in a growth medium (Sigma-Aldrich; Merck Millipore) for 30 min at 37°C and 5% CO 2 . The fluorescence was measured at 485/525 nm (Ex/Em) based on the method of Muthuraman et al (10) (Axiovert 2000; Carl Zeiss AG).…”

Combining thermogalvanic corrosion and thermogalvanic redox couples for improved electrochemical waste heat harvesting

“…Thermogalvanic cells (or thermocells or thermoelectrochemical cells) can convert waste heat into an electrical current [1][2][3]. Principally, such assemblies require two electrodes that are at different temperatures, in contact with a common (solid or liquid) electrolyte and a suitable redox couple.…”
