It is known that the carbon atoms become more positive as the neighboring doped nitrogen and sulfur atoms are more electronegative27,29. This change of the charge state of the carbon atoms causes the nearby oxygen functional groups to be polarized and activated to anchor sulfur by covalent ...
While for covalent-ionic bonded fibers, the weak interface at fiber/surface coating and uneven distribution of GO lead to lower IFSS. This work provides valuable guidance for interphase design in order to obtain high performance composites with good interfacial adhesion....

Using your knowledge of how CO2 dissolves and reacts in water, explain why global increases in atmospheric CO2 should cause a decrease in the pH of ocean water. Is the reaction of calcium chloride with sodium carbonate ionic or covalent?
Developing novel techniques to convert lignin into sustainable chemicals and functional materials is a critical route toward the high-value utilization of
carbon dioxide capture materials in time. In this paper, the main technologies of CO2capture are reviewed, with emphasis on the latest research status of CO2capture materials, such as amines, zeolites, alkali metals, as well as emerging MOFs and carbon nanomaterials. More and more research on ...
As used herein, “receptor agent” means any element or compound capable of interacting with intermediate species (e.g. via covalent or ionic bonding) to produce non-carbon dioxide end products. Some non-carbon dioxide end products that may be produced include carbonate-containing end products (...
Pyrolyzed biomass-derived carbon is non-graphitizing, hard carbon with varying textures, morphologies, and degrees of crystallinity. It provides short diffusion paths for ionic and electron transport and can therefore be an attractive material for anodes in metal-ion batteries. The solid structure of ...
Namely, site A can be considered as an ionic or GIC site. On the other hand, band B may result from the existence of molecular Li2 in the PPP-based carbon. A small chemical shift for band B is consistent with a Li2 molecule model. This model is also consistent with a Lorentzian ...
