It is generally accepted that the formation of kerogens is the result of the so-called depolymerization-recondensation pathway (Tissot and Welte, 1984; Durand, 1980), Thus, naturally occurring macromolecular substances such as polysaccharides and protein

In subject area: Physics and Astronomy Dissolved organic matter refers to organic compounds found in water bodies, playing crucial roles in global cycles, environmental processes, and biodiversity. It contains a vast array of diverse molecules that hold valuable information about aquatic ecosystems. AI...
Bicyclobutanes are among the most highly strained isolable organic compounds and their associated low activation barriers to reactivity make them intriguing building-blocks in organic chemistry. In recent years, numerous creative synthetic strategies exploiting their heightened reactivity have been presented ...
Si/SiO2, glass and polyimide were used as the substrates to fabricate the BPEA single crystal arrays. The Si/SiO2substrates were cleaned in hot sulphuric acid (98%) and hydrogen peroxide (V/V = 7:3) mixed solution for 10 minutes to get rid of organic compounds and then cleaned with...
It covers ultraviolet spectroscopy, infrared spectroscopy, nuclear magnetic resonance spectroscopy and mass spectrometry, which are widely used in characterization of organic compounds. The course would help students to make full use of these tools in order to accurately analyze structures of organic ...
metal-organic frameworks nucleation and growth controllable synthesis hierarchical assemblies superstructures morphology composites catalysis Main Text Introduction It has been widely observed that special functions of natural systems originate from their compositions, sizes, morphologies, and structures. For exampl...
In this Review, we describe the mechanisms and processes operating at the mineral–organic interface as they relate to OM transformation dynamics. A broad set of interactions occur, with minerals adsorbing organic compounds to their surfaces and/or acting as catalysts for organic reactions. Minerals ...
Saturated N-heterocycles are ubiquitous structures among natural products and biologically active compounds, but methods to edit the ring size of these substructures are scarce. Now the ring expansion of unactivated cyclic amines has been achieved via sequential Ru-catalysed C‒C bond formation, retro...
