36, 24 different MMT/CNF/gelatin/glycerol ratios were selected, and 6 sets of all-natural nanocomposites were prepared using three different gelatin sources (cold fish skin, porcine skin and bovine skin) and three different MMT sizes (large-, medium- and small-sized nanosheets). Subsequently, ...
Summary: The novel semi-natural Schiff bases were synthesized with the reaction of the natural compounds usnic acid and naringenin extracted and purified in natural sources and chemically modified silica gel. Cu(II), Ni(II), Co(II) and Mn(II) complexes of the ligands were synthesized and the...
The clay, which exists in a biphase of silicates and silica, was reacted with Mg vapor at 650 °C (the melting temperature of Mg) to produce the SiNSs. As expected, the magnesiothermic reaction generated a large amount of exothermic heat. Metal salts (for example, NaCl, KCl, and MgCl2...
HA can imbibe water to achieve considerable mechanical robustness. As an essential component of the endogenous or synthetic ECM, HA has been proven to be effective at inducing cellular proliferation [25,26]. In contrast to animal tissue, which has potential pathogenicity and limited sources, HA ...

Column chromatography over silica gel eluted with increasing polarity was used to separate the more active fractions (EEF and BUF) (Figure 4). Figure 4. Phenolic antioxidant compounds from walnut kernels, Zhai et al. [76]. All the derivative compounds (7a–f and 8) were screened for α,...
Accordingly, the global consumption of natural rubber is considerable. In 1990, natural rubber consumption amounted to 5.2 million metric tons, but has increased significantly since then. Chinese natural rubber consumption China is by far the largest consumer of natural rubber worldwide. China uses ...
