(1) Background: Safety problems associated with aflatoxin B (AFB) contamination have always been a major threat to human health. Removing AFB through adsorption is considered an attractive remediation technique. (2) Methods: To produce an adsorbent with a high AFB adsorption efficiency, a magnetic reduced graphene oxide composite (FeO@rGO) was synthesized using one-step hydrothermal fabrication.

It is highly urgent and significant to clarify the regulatory mechanism of peanuts in response to . In this study, transcriptome and proteome profiling were combined to provide new insights into the molecular mechanisms of peanut stems after infection.

MnO@CoO composite was successfully prepared by in-situ growth of nano-particle-like CoO on nano-rod-like MnO. The hybrid products had (121), (310), (311), (400) and (511) crystal planes, rod-like and point-like structures were observed.

To confirm the structure and to assess biological activity, we semi-synthesized 1 a from commercially available oleanolic acid. A series of novel 1 a derivatives was then designed and synthesized for a structure-activity relationship (SAR) study.
