An Intercalated heterostructural g-C3N4/TiO2/HNTs supported photocatalyst was successfully prepared via sol–gel and calcination methods. The introduction of HNTs and the g-C3N4-TiO2 heterojunction effectively enhanced the charge transfer and separation efficiency of photogenerated electron–hole pairs, which endued the g-C3N4/TiO2/HNTs hybrid material with an outstanding photoelectric performance and good stability. And an obviously enhanced photocatalytic activity was exhibited by photodegrading ciprofloxacin compared with pure TiO2. Furthermore, the main active species were detected through trapping experiment and ESR spin-trap technique with DMPO, which confirmed that the O2− and the h+ were the main active species in the photocatalytic system.

The easy scalability and low cost of range-free localization algorithms have led to their wide attention and application in node localization of wireless sensor networks. However, the existing range-free localization algorithms still have problems, such as large cumulative errors and poor localization performance. To solve these problems, an incremental strategy-based residual regression network is proposed for node localization in wireless sensor networks. The algorithm predicts the coordinates of the nodes to be solved by building a deep learning model and fine-tunes the prediction results by regression based on the intersection of the communication range between the predicted and real coordinates and the loss function, which improves the localization performance of the algorithm. Moreover, a correction scheme is proposed to correct the augmented data in the incremental strategy, which reduces the cumulative error generated during the algorithm localization. The analysis through simulation experiments demonstrates that our proposed algorithm has strong robustness and has obvious advantages in localization performance compared with other algorithms.

The purpose of this work designed hybrid-structured and plasma effect photocatalyst of Ag/In2O3/TiO2/HNTs via sol–gel and photo-reduction methods. The structures, morphologies, optical and photoelectric performances of as-prepared photocatalysts were characterized via XRD, TEM, XPS, BET, UV–vis DRS, PL and photocurrents. The photocatalytic activity was evaluated by degradation of TC. The results showed that the hybrid-structure and plasma effect can effectively cause the multi-transfer of electrons and increase the separation rate of electron and hole pairs which obtained high photocatalytic activity. The photocatalytic degradation processes reveal that O2− and h+ are major active species.

Lactobacillus plantarum is an essential probiotic in the human gastrointestinal tract. L. plantarum BF_15, a functional probiotic isolated from the feces of breast-fed infants, has been reported in many in vitro and in vivo studies with strong gastrointestinal adaptability and outstanding anti-oxidative activities. Therefore, the whole genome of L. plantarum BF_15 was sequenced. Several genes, encoding the gastrointestinal adaptability-related proteins, were identified, including genes related to gastrointestinal environment-induced stress resistance, adhesive performance, and ability to transport and metabolize resistant starch and oligosaccharides. Genes related to alleviating oxidative stress were also found. Further functional verification was carried out by RT-qPCR on the 10 and 12 key adhesion and antioxidant genes. Overall, this study might provide a critical basis for L. plantarum BF_15 as a potential candidate for probiotics.

In this work, we reported one kind of photocatalytic and antibacterial materials, Ag/Ag2S/reducedgraphene oxide (rGO), which prepared by the hydrothermal and UV-light-assisted reduction methods. The Ag2S nanoparticals were well dispersed on the surface of rGO as revealed by series ofcharacterization. The obtained Ag/Ag2S/rGO photocatalyst showed excellent photocatalytic degradationefficiency of 87.6% for ciprofloxacin (CIP) under visible light irradiation and outstanding antibacterialactivity for Escherichia coli (E. coli) which reached to 97.76% in 24 h. The trapping of active species showedthat the hydroxyl radicals, holes and superoxide radicals played important roles in the photocatalyticdegradation of CIP processes.
