Clarifying the reaction process and specific mechanism between variable-valence elements and oxidized carbon nanoparticles is essential to evaluate the environmental impact of carbon nanomaterials. In this study, the photocatalytic reduction of Cr(VI) on oxidized carbon nanotubes (OCNTs), oxidized graphene ribbons (OGRs), and graphene oxide sheets...
Due to the widespread applications, graphene oxide (GO) possibly interact with natural minerals to form new heteroaggregates in the environment, which will affect the environmental processes of heavy metals as an example of arsenic. In this work, photo-oxidation and sequestration behaviors of As(III) on β-FeOOH/GO (FeGO) heteroaggregates were explo...
The application of graphene oxide (GO) in the photoelectronic materials are greatly restricted by the ineffective carrier separation and mobility, as well as the poor utilization of visible light. In this study, a strategy is proposed to overcome these disadvantages via the fabrication of van der Waals heterostructure. The goal heterostructure, Pc-...

The distribution characteristics of typical heavy metals (HMs) and Pb isotopic compositions in profile soils from different areas were investigated in Baiyin district, northwest China. The soil samples from the ore district and the sewage irrigation area showed an obvious enrichment of HMs in different depths, and the difference in the longitudinal...
The transport of radiocesium (RCs) in granite has attracted great concerns for the consideration of a long-term safety assessment and performance evaluation of the nuclear waste disposal repository. In this study, the transport behaviors of Cs⁺ in granite were addressed and quantified by column experiments, sequential extraction, and a convection-d...
The photocatalytic U(VI) reduction provides a promising strategy for extracting uranium from seawater. However, seawater contains ∼2.75 mM carbonates, which would seriously inhibit the photocatalytic reduction of U(VI), restricting the practical application of this method. This study is devoted to realizing the photo-reduction of U(VI) in carbonate...
Due to the critical tumorigenic role of fused NTRK genes in multiple cancers, TRK kinases have attracted extensive attention as a drug discovery target. Starting from an indazole based scaffold, through the type II kinase inhibitor fragments hybrid design approach with a ring closure strategy, we discovered a novel potent type II TRK kinase inhibit...
The synergetic sequestration of sorption and photocatalysis promises unique advantage in the environment remediation; however, the mechanism, especially the photocatalytic sites, is still ambiguous in carbon catalysts. Here, a metal-free three-dimensional carbon framework, named P-OGR, was fabricated via the assembly of oxidized graphene ribbons (O...
As the important anions in the high-level radioactive waste (HLRW), and the sorption behaviors of Se(VI) and Se(IV) on Beishan granite are important to the safe evaluation and performance assessment of the deep geological repository for HLRW in China. In this study, the sorption behaviors of Se(IV) and Se(VI) on Beishan granite were investigated un...

... The chromium oxidation states + 3 (Cr((III))) and + 6 (Cr((VI))) are primarily found in wastewaters, and the presence of Cr(VI) represents a great concern due to its high toxicity even at low concentrations. Heterogeneous photocatalysis is suggested as a suitable treatment for Cr(VI) reduction to the less toxic and less soluble Cr(III) (Ding et al. 2023). Different nanomaterials and nanocomposites have been evaluated for photocatalysis processes and also in heavy metal detection applications. ...

... Photocatalytic oxidation is undoubtedly a competitive technology due to its effective and environmentally friendly feature. Recently, more and more photocatalysts have been developed, for example Pc-GO [25], g-C 3 N 4 /TiO 2 [26], C 3 N 4 /WO 3 [27]. However, it is still extremely desirable for the catalysts that simultaneously complete the oxidation and sequestration of As(III). ...
... We found FTIR absorption bands at ~3400 cm -1 caused by -O-H stretching hydroxyl groups [33]. Two FTIR bands were observed at 1461 cm -1 and 1586 cm -1 , which are attributed to symmetric and asymmetric stretching vibrations of the carboxylate groups respectively [34]. ...

... Considering that the sorption coefficient of mineral assemblage is relatively difficult to obtain, it is attractive to predict the sorption properties of mineral assemblages through information from grain-scale minerals. Based on this idea, the component additivity (CA) model was developed and frequently used Wang et al. 2021;Zhang et al. 2016). In the CA method, the sorption characteristic of the mineral assemblage is calculated by mathematically combining the grainsize sorption contributions of individual mineral phases according to individual sorption coefficients and the mineral component contents. ...

... These mutations can occur in the solvent-front, gatekeeper residues, and the xDFG motif of the TRK enzyme. Several compounds have been developed to address this problem [96][97][98][99]. Among them, selitrectinib (LOXO-195) and repotrectinib (TPX-0005) have entered clinical trials and are regarded as second-generation TRK inhibitors. ...

... The results showed that after adsorption, the pore structure of S-PC did not change significantly, indicating that the structure of S-PC was relatively stable, which may also be one of the reasons why S-PC could be used many times (Fig. 8a). Furthermore, the EDS images showed that the distributions of C, O and Cr on S-PC were strongly correlated, indicating that both C and O groups were adsorbed and fixed the Cr [48]. To reveal the Cr(VI) species adsorbed by the C and O species, S-PC samples were compared before and after adsorption and analyzed with an XPS atlas. ...
... Fission-based nuclear energy is nowadays a reliable power source which arises as a consequence of the reduced availability of fossil fuels as well as to counter the threat of climate change [1,2]. Consequently, a large amount of long-term nuclear waste had been produced because of the subsequent increase of elements processing to be used in fuel and weapons [3,4]. ...
