The sensitivities of CH4 and CD4 differ by about 2 percent and are probably equal within the experimental uncertainty. The total ionization is apparently the same for CH4, CH3D, and CH?D2. The low value for CHD3 is not significant in view of the uncertainty in this spectrum. The difference in the total ionization of CH4 and CD4, however, is greater than the estimated error; and since the number...

Abstract There is growing interest in biodegradable and bio‐based materials that can replace conventional plastics applications such as packaging. Polymers based on 2,5‐furandicarboxylic acid (FDCA) have been proposed analogues for polymers terephthalic acid. However, they tend to be brittle, exhibit limited biodegradability, there are few examples of biocomposites from these polymers. Describe...

Life cycle assessment shows the potential benefits of N -vinyl-2-pyrrolidone synthesis from succinic acid. Given right catalyst, replacing incumbent fossil technology can be cost-neutral, while slashing CO 2 equivalent emissions by 50%.

In the title compound, 2C(4)H(7)N(2) (+)·C(4)H(4)O(4) (2-)·C(4)H(6)O(4), the asymmetric unit consists of two 4-methyl-imidazolium cations, one succinate dianion and one netrual succinic acid mol-ecule and within the latter components, the C-O, C=O and C O bonds are clearly evidenced from their relative distances. In the crystal structure, the individual components are linked by inter-molecular ...

In the title compound, 2C(3)H(5)N(2)S(+)·C(4)H(4)O(4) (2-)·C(4)H(6)O(4), the thia-zolium ring is almost planar, with the maximum deviation from planarity being 0.0056 (8) Å for the C atom carrying the amine substituent. The N atom of the 2-amino-thia-zole mol-ecule is protonated. Both the anion and the acid lie across inversion centres. The crystal packing is consolidated by inter-molecular O-H...

The asymmetric unit of the solvated title salt, 2C(3)H(7)N(6) (+)·C(4)H(4)O(4) (2-)·C(4)H(6)O(4)·2H(2)O, contains one essentially planar melaminium (2,4,6-triamino-1,3,5-triazin-1-ium) cation (r.m.s. deviation of the non-H atoms = 0.0097 Å), one-half of a succinate anion, one-half of a succinic acid solvent mol-ecule and one water molecule of crystallization; full mol-ecules are generated by in...
