The electrochemical oxidation of dye wastewater with the cathode modified by quinones has beeninvestigated. Under the optimal conditions, the decolorization efficiency can reach 96.0% after 120 min. The addition of tert-butanol significantly decreased the decolorization efficiency, suggesting theinvolvement of -OH radicals in the decomposition of H2O2. A potential difference may result in a quinoneradical on the cathode which can catalyze the reduction of O2 to H2O2. UV–vis spectrum and GC/MSanalysis revealed that the dye molecule was firstly initiated by the cleavage of –N55N–, and decomposedto aromatic intermediates, further degraded to ring opening products and finally mineralized.

This paper investigates the problem of relative motion control for spacecraft rendezvous on an arbitrary elliptical orbit. The simplified dynamic model describing the relative motion between the chaser spacecraft and the target spacecraft is established via using transformed variables. Due to the presence of time variant parameters in this novel model, robust control scheme and adaptive control scheme are designed to solve the rendezvous problem. Theoretical analyses and simulation results demonstrate the effectiveness of the proposed methods.

Background Diethylstilbestrol (DES) has been shown to disrupt the morphology and proliferation of gubernaculum testis cells. Objective This study aimed to elucidate the mechanism underlying DES induced damage to gubernaculum testis based on proteome analysis. Results Neonatal mice were exposed to DES or control vehicle and the gonads were collected for isobaric tags for relative and absolute quantitation based proteomics analysis. We found that at the early and late stages of gubernaculum development, treatment with different concentrations of DES upregulated the expression of proteins which were generally involved in several function categories including single-organism process, cellular process, binding, catalytic activity, cell part and organelle. KEGG pathway analysis showed that cardiac muscle contraction, oxidative phosphorylation, calcium signaling and cGMP-PKG signaling pathway were the most dysregulated pathways associated with DES in the late stage of gubernaculum development, while steroid biosynthesis was the only enriched pathway in the early stage of gubernaculum development. Conclusion Proteomics profi ling and functional analysis reveal new clues on how DES interferes with cellular processes and disrupts the development of gubernaculum. These findings have potential applications in the treatment of genitourinary diseases such as cryptorchidism.

Electrochemical oxidation of Acid Red 3R was investigated in the presence of Fe2O3/γ-Al2O3 as Fenton-like catalyst in the reactor. The results showed that the catalyst had catalytic activity in theelectrochemical process. Under the optimal conditions, the decolorization efficiency reached 77.2% in100 min. UV–vis spectrum and LC–MS analysis revealed that the dye molecule was firstly decomposed toaromatic intermediates, further degraded to ring opening products and finally mineralized. The azo dyedegradation might be attributed to strong oxidant -OH that produced from the synergetic effect ofbetween Fe2O3/γ-Al2O3 catalyst and electrochemical system.
