Products from incomplete combustion of organic carbon (black carbon) are ubiquitous in the environment. However, the available information on black carbon in marine dissolved organic matter (DOM), one of the largest organic carbon pools, is extremely scarce. The objective of this study was to intr...
Black carbon (BC) is ubiquitous in the environments and participates in various biogeochemical processes. Both positive and negative effects of BC (especially biochar) on the ecosystem have been identified, which are mainly derived from its diverse physicochemical properties. Nevertheless, few studies sy...
It was found that the addition of the carbon black contributed to increase the wear resistance of UHMWPE, which was attributed to the load-carrying action of the carbon black particulates as the filler. The counterpart surface roughness had a great influence on the tribological behavior of the ...
Soot black carbon (here expressed as GBC) is present in sediments of Central Park and Prospect Park Lakes, New York City (NYC), and peaks in the middle of the 20th Century at the highest values (1-3% dry weight) ever reported in urban lakes. During that period (approximately 1940-1970...
bycompression moulding.72The lubricants used may be different, i.e. solid (such asmolybdenum disulphide(MoS2) and carbon black (CB)) or liquid (such as perfluoropolyether (PFPE)). The UHMWPE and the lubricants form three-dimensional networks, where the lubricant is evenly spread over the ...
The natural products synthesized by organisms that were living a long time ago gave rise to their molecular fossils. These can consist of either the original unchanged compounds or they may undergo peripheral transformations in which their skeletons rema
The biosynthesis of these 5-carbon monomers was achieved by the mevalonate (MVA) and the 2-C-methyl-D-erythritol-4-phosphate (MEP) pathways [2, 3]. However, a complete understanding of these highly complex biosynthetic pathways has been elucidated in only few plants. The MVA pathway is a ...
Enzymatic breakdown of sphingomyelin by sphingomyelinase (SMase) is the main source of the membrane lipids, ceramides, which are involved in many cellular physiological processes. However, the full-length structure of human neutral SMase has not been res
Water-soluble organic carbon Source apportionment Molecular compositions Optical properties Wet deposition 1. Introduction Precipitation is one part of the most important segment of the hydrological cycle, as it plays the main role for water in the atmosphere to return to the earth's surface (Bonacci...
Lamin A is a nuclear intermediate filament protein critical for nuclear architecture and mechanics and mutated in a wide range of human diseases. Yet little is known about the molecular architecture of lamins and mechanisms of their assembly. Here we use
