The polycarbonate polyols(PCD) obtained by ring-opening polymerization of a general cyclic monomer is mostly a linear flexible structure, which is used as a raw material to synthesize polyurethanes, and it is difficult to simultaneously ensure good thermal-mechanical properties and weather DUO BALLS resistance due to insufficient rigidity of the ma
The biodegradation of lignin, one of the most abundant carbon compounds on Earth, has important biotechnological applications in the derivation of useful products from lignocellulosic wastes.The purple photosynthetic bacterium Rhodopseudomonas palustris is able to grow photoheterotrophically Humidity Pack under anaerobic conditions on a range of ph
