Application of gallium nitride nanostructures and nitrogen doped carbon spheres as supports for the hydrogenation of cinnamaldehyde.
This paper reports on the synthesis and use of nanostructures of gallium nitride (GaN NSs) and nitrogen doped carbon spheres (NCSs) as support materials for the hydrogenation of cinnamaldehyde. This s...Read More
Cellular metabolism converts available nutrients into usable energy and biomass precursors. The process is regulated to facilitate efficient nutrient use and metabolic homeostasis. Feedback inhibition...Read More
Pre-oxidation with KMnO4 changes extra-cellular organic matter's secretion characteristics to improve algal removal by coagulation with a low dosage of polyaluminium chloride.
Microcystis aeruginosa was used to study the effect of KMnO4 pre-oxidation on algal removal through coagulation with polyaluminium chloride (PAC). KMnO4 pre-oxidation improved the coagulation efficien...Read More
Coccolithophores are marine algae that use carbon for calcification and photosynthesis. The long-term adaptation of these and other marine algae to decreasing carbon dioxide levels during the Cenozoic...Read More
Solar energy assisted starch-stabilized palladium nanoparticles and their application in C-C coupling reactions.
Present work reports a novel one step, greener protocol for the synthesis of starch-stabilized palladium nanoparticles (PdNPs) with an average particle diameter of 30-40 nm. These particles were stabl...Read More
We report the synthesis of biogenic silver nanoparticles using chlorogenic acid as a bioreducing agent. Chlorogenic acid is a polyphenol compound abundant in coffee. UV-Vis spectra showed the characte...Read More
Electrocatalytic activity of silver nanoparticles modified glassy carbon electrode as amperometric sensor for hydrogen peroxide.
A simple chemical route has been applied for the preparation of quasi-spherical silver (Ag) nanoparticles (NPs) with average diameter of 265 and 8 nm. The as prepared products were characterized by po...Read More
[Transformation of humic substances of highly oxidized brown coal by the basidiomycetes fungi Trametes hirsuta and Trametes maxima].
The ability of the white rot basidiomycetes Trametes hirsuta and Trametes maxima to transform coal humic substances (HS's) under the conditions of solid phase cultivation in the presence or absen...Read More
Carbon (C) uptake rates in many forests are sustained, or decline only briefly, following disturbances that partially defoliate the canopy. The mechanisms supporting such functional resistance to mode...Read More
Earthworm effects on the incorporation of litter C and N into soil organic matter in a sugar maple forest.
To examine the mechanisms of earthworm effects on forest soil C and N, we double-labeled leaf litter with 13C and 15N, applied it to sugar maple forest plots with and without earthworms, and traced is...Read More
Ninety per cent of marine organic matter burial occurs in continental margin sediments, where a substantial fraction of organic carbon escapes oxidation and enters long-term geologic storage within se...Read More
[Effect of low-temperature vernalization on metabolism of carbon and nitrogen of Isatis indigotica].
The aim of the present study is to investigate the effect of low temperature vernalization on metabolism change of carbon and nitrogen of Isatis indigotica.The Yunnan and Beijing I. indigotica seedlin...Read More
Microbial community characterization, activity analysis and purifying efficiency in a biofilter process.
The growth and metabolism of microbial communities on biologically activated carbon (BAC) play a crucial role in the purification of drinking water. To gain insight into the growth and metabolic chara...Read More
Optimisation of chemical purification conditions for direct application of solid metal salt coagulants: treatment of peatland-derived diffuse runoff.
The drainage of peatland areas for peat extraction, agriculture or bioenergy requires affordable, simple and reliable treatment methods that can purify waters rich in particulates and dissolved organi...Read More
Influence of fuel mass load, oxygen supply and burning rate on emission factor and size distribution of carbonaceous particulate matter from indoor corn straw burning.
The uncertainty in emission estimation is strongly associated with the variation in emission factor (EF), which could be influenced by a variety of factors such as fuel properties, stove type, fire ma...Read More
Common practice when validating the cleaning of medical devices is to employ clinically relevant test soils as a challenge to the cleaning process. During use, medical devices may come into contact wi...Read More
Currently, there are very few provisions for recycling in theatres. We measured the weight of clinical waste for several orthopaedic operations. This waste was then examined and sorted into domestic w...Read More
The utilization of carbon dioxide for the production of valuable chemicals via catalysts is one of the efficient ways to mitigate the greenhouse gases in the atmosphere. It is known that the carbon di...Read More
Low-temperature Preparation of Functional Carbon Nanocapsules via Self-assembly and Carbonization of Hexayne Amphiphiles.
The labeling of living cells with carbon nanoparticles has been increasingly studied both in vivo and in vitro, but concerns about the potential cytotoxicity of these nanoprobes are also increasing. I...Read More

[Utilization of different carbon sources by soil and endophytic strains of Penicillium funiculosum Thom].
The ability of soil and endophytic strains of P. funiculosum to accumulate biomass under cultivation conditions in media containing carbon sources from mono- to polysaccharides has been studied. It ha...Read More
Quantifying the sampling error in tree census measurements by volunteers and its effect on carbon stock estimates.
A typical way to quantify aboveground carbon in forests is to measure tree diameters and use species-specific allometric equations to estimate biomass and carbon stocks. Using "citizen scientists...Read More
Hydrophilic carbon nanoonions coated with carbon nanobubbles by laser ablation of carbon black suspension.
Hydrophilic carbon nanoonions coated with carbon nanobubbles were synthesized by long-pulse-width laser ablating of carbon black particles suspended in water. The high resolution TEM (HTREM), selected...Read More
Response to comment on "Radiative absorption enhancements due to the mixing state of atmospheric black carbon".
Jacobson argues that our statement that "many climate models may overestimate warming by BC" has not been demonstrated. Jacobson challenges our results on the basis that we have misinterpret...Read More
