Carbon‒Carbon Bond Activation of Ketones
Trends in Chemistry, 2020C−C bond activation has emerged as an increasingly useful approach for constructing complex molecular scaffolds through unusual bond-disconnection strategies. As a common versatile functional group, ketones provide an excellent handle and platform for C−C bond activation reactions.

Journal of Colloid and Interface Science, 2003
Four activated carbons (S1-S4) possessing different structural characteristics were prepared by carbonization of commercial resins (used for ion exchange) and subsequent activation. Their textural parameters were determined on the basis of nitrogen adsorption-desorption at 77.4 K, analyzed by applying several local and overall adsorption isotherm ...

Future Medicinal Chemistry, 2018
Mammalian carbonic anhydrases (CAs; EC 4.2.1.1) of which 16 isoforms are known, are involved in important physiological functions. Their inhibition is exploited pharmacologically for the treatment of many diseases (glaucoma, edema, epilepsy, obesity, hypoxic tumors, neuropathic pain, etc.) but the activators were less investigated till recently.

Advanced activated carbon monoliths and activated carbons for hydrogen storage
Microporous and Mesoporous Materials, 2008Abstract Results of hydrogen storage are presented for advanced activated carbon monoliths (ACM) and activated carbons (AC). It is shown that materials having both, high micropore volume and high packing density, are required to reach a high hydrogen adsorption capacity in volumetric basis.

A procedure to form powder activated carbon into activated carbon monolith
The International Journal of Advanced Manufacturing Technology, 2015Activated carbon monolith was prepared using powder-activated carbon, methyl cellulose as organic binder, and bentonite as clay binder. The used organic binder contrib- uted to the plasticity of powder-activated carbon for well ex- truding into well-shaped bodies, and the used clay binder con- tributed to the mechanical strength of the bodies.

Activation of carbonic anhydrase isozymes
2000CA inhibition by sulphanilamide, discovered in England by Mann and Keilin (1940) and its activation by different classes of compounds, reported in Germany by Leiner (1940), although simultaneous, had completely different consequences for CA research.

Trihalomethanes adsorption on activated carbon fiber and granular activated carbon
Water, Air, & Soil Pollution, 1997Isotherms and the effects on activated carbon fiber (ACF), compared with granular activated carbon (GAC), adsorption of trihalomethans (THMs) in water were studied. It was found that the isotherms for ACF or GAC were not agree to Langmuir equation well, but successfully correlated by Freundlich equation, and the coefficients of Freundlich isotherm were

Osteoblast activity on carbonated hydroxyapatite
Journal of Biomedical Materials Research Part A, 2012AbstractHydroxyapatite (HA), has been used commonly as a bone substitute and as a scaffold in bone tissue engineering. However it has certain drawbacks such as limited biodegradability and osteointegration properties. Other forms of HA, for example, carbonated hydroxyapatite (CHA) could prove to have enhanced bioactivity as they more closely mimic the ...

Adsorption of Carbon Dioxide on Activated Carbon
Journal of Natural Gas Chemistry, 2006The adsorption of CO2 on a raw activated carbon A and three modified activated carbon samples B, C, and D at temperatures ranging from 303 to 333 K and the thermodynamics of adsorption have been investigated using a vacuum adsorption apparatus in order to obtain more information about the effect of CO2 on removal of organic sulfur-containing compounds ...
