Hydrothermal, KOH-assisted synthesis of lignin-derived porous carbon for supercapacitors: value-added of lignin and constructing texture properties/specific capacitance relationships

Journal of Materials Research and Technology, 2022
Searching for good-natured feedstocks and understanding the texture property of porous carbon/specific capacitance relationships have long been highly desirable.

Direct Measurement of Specific Membrane Capacitance in Neurons [PDF]

Biophysical Journal, 2000
The specific membrane capacitance (C(m)) of a neuron influences synaptic efficacy and determines the speed with which electrical signals propagate along dendrites and unmyelinated axons. The value of this important parameter remains controversial. In this study, C(m) was estimated for the somatic membrane of cortical pyramidal neurons, spinal cord ...

Activated Carbon Aerogel as an Electrode with High Specific Capacitance for Capacitive Deionization

Processes, 2022
In this study, carbon aerogels (CAs) were synthesized by the sol-gel method, using environmentally friendly glucose as a precursor, and then they were further activated with potassium hydroxide (KOH) to obtain activated carbon aerogels (ACAs). After the activation, the electrochemical performance of the ACAs was significantly improved, and the specific

Capacitation of Rabbit Spermatozoa: Species Specificity and Organ Specificity.

Experimental Biology and Medicine, 1967
SummaryIt has been found that washed rabbit sperm may be capacitated in the uterus of an estrous rabbit, rat, and dog, indicating that the capacitation mechanism is similar in these species. It was shown that washed rabbit sperm are capacitated only in the uterus and oviduct of the estrous rabbit and not in the bladder, colon and knee joint, indicating

Effect of mesoporosity on specific capacitance of carbons [PDF]

Carbon, 2009
The study compares the structural and electrochemical properties of 12 porous carbons based on phenolic resins, using both aqueous (H2SO4) and aprotic ((C2H5)4NBF4 in acetonitrile) electrolytes. It appears that they fit into the general pattern observed for other carbons.
