The electrochemical performance of all-solid-state lithium batteries (ASSLBs) can be prominently enhanced by minimizing the detrimental degradation of solid electrolytes through their undesirable side reactions with the conductive carbon additives (CCAs) inside the composite cathodes. Herein, the well-defined MoNiN nanosheets embedded onto the N-doped porous carbons (NPCs) substrate are successfully synthesized (Mo-Ni@NPCs) as CCAs inside LiCoO for LiPSCCl (LPSCl)-based ASSLBs. This nano-composite not only makes it difficult for hydroxide groups (-OH) to survive on the surface but also allows the in situ surface reconstruction to generate the ultra-stable MoS-MoNiN heterostructures after the initial cycling stage.

Transition-metal nitrides (TMNs) have garnered considerable attention for energy conversion applications owing to their exceptional electronic structures and high catalytic activities. However, the scarcity of active sites in TMNs impedes their large-scale application. This study describes the use of wetness impregnation and ionic-liquid methods to enhance the electrocatalytic efficiency of molybdenum nitride (MoN) atomic clusters finely dispersed on nitrogen-doped carbon (MoN@NC) substrates.

The electrochemical nitrogen reduction reaction (NRR) to synthesize ammonia (NH) is considered as a promising method due to its approvable advantages of zero-pollution emission, feasible reaction proceedings, good safety and easy management. The multiple efforts have been devoted to the exploration of earth-abundant-element-based nanomaterials as high-efficiency electrocatalysts for realizing their industrial applications. Among these, the Ni-based nanomaterials is prioritized as an attractive non-noble-metal electrocatalysts for catalyzing NRR because they are earth-abundance and exceedingly easy to synthesize as well as also delivers the potential of high electrocatalytic activity and durability.

Catalysts made of CuO/BiO nanoparticles supported on g-CN were synthesized using a MOF-derived strategy. The activation of CuO to CuCCCu species and stabilization of the catalyst were facilitated by the synergistic effect of the CuO/CN interface and CuO nanoparticles, resulting in enhanced catalytic efficacy in the ethynylation of formaldehyde.

Background: Hepatocellular carcinoma (HCC) patients have a poor prognosis after radio-frequency ablation (RFA), and investigating the risk factors affecting RFA and establishing predictive models are important for improving the prognosis of HCC patients.

Methods: Patients with HCC undergoing RFA in Shenzhen People's Hospital between January 2011 and December 2021 were included in this study. Using the screened independent influences on recurrence and survival, predictive models were constructed and validated, and the predictive models were then used to classify patients into different risk categories and assess the prognosis of different categories.

CO methanation has attracted considerable attention as a promising strategy for recycling CO and generating valuable methane. This study presents a niobium-doped CeO-supported Ni catalyst (Ni/NbCe), which demonstrates remarkable performance in terms of CO conversion and CH selectivity, even when operating at a low temperature of 250 °C. Structural analysis reveals the incorporation of Nb species into the CeO lattice, resulting in the formation of a Nb-Ce-O solid solution.

Sodium-ion batteries (SIBs) are investigated as promising alternatives to lithium-ion batteries (LIBs) on account of the economical abundance and reliable availability of sodium, as well as its analogous chemical properties compared to lithium. Nevertheless, the performance of SIBs is severely restricted by the availability of satisfactory cathode nanomaterials with stable frameworks to accommodate the transportation of large-sized Na ions. These challenges can be effectively resolved when exploiting Prussian blue (PB) and its analogs (PBAs) as SIB cathodes.

Article Synopsis
  • The study investigates the effectiveness of adjuvant transarterial chemoembolization (TACE) for improving survival in hepatocellular carcinoma (HCC) patients post-hepatectomy, involving 1491 patients analyzed from various medical centers in China.
  • After matching groups based on clinical characteristics, results showed that patients who received adjuvant TACE had significantly better disease-free survival (DFS) and overall survival (OS) rates compared to those who did not.
  • The findings suggest that adjuvant TACE could be beneficial for HCC patients post-surgery, as it seems to enhance survival rates and enable patients to pursue more aggressive subsequent antitumor therapies.

Background: Preeclampsia is a major cause of increased maternal and fetal morbidity and mortality, which is closely related to the abnormal maternal immune response. The skew of decidual macrophage polarization toward M1 phenotype has been proved to promote the pathogenesis of preeclampsia. However, it's not easy to monitor the change of decidual macrophage subtypes.

Herein, V-doped cobalt hydroxides grown on carbon cloth (V-Co(OH)/CC) were prepared hydrothermal method. The incorporation of V can trigger phase transition and tune the local electronic structure of Co(OH), thereby improving the intrinsic alkaline HER activity. We find that the V-Co(OH) dominated by β-Co(OH) exhibits excellent HER activity with only 83 mV overpotential at a current density of 10 mA cm, which outperforms most reported hydroxide-based catalysts and even surpasses the commercial Pt/C at large current density (>160 mA cm).

Potassium-ion batteries (KIBs) are gradually being considered as an alternative for lithium-ion batteries because of their non-negligible advantages such as abundance and low expenditure of K, as well as higher electrochemical potential than another alternative─sodium-ion batteries. Nevertheless, when the electrode materials are inserted and extracted with large-sized K ions, the tremendous volume change will cause the collapse of the microstructures of electrodes and make the charging/discharging process irreversible, thus disapproving their extended application. In response to this, we put forward a feasible strategy to realize the in situ assembly of layered MoSe nanosheets onto N, P codoped hollow carbon nanospheres (MoSe/NP-HCNSs) through thermal annealing and heteroatom doping strategies, and the resulting nanoengineered material can function well as an anode for KIBs.

Heterogeneous photo-Fenton catalysts prepared by doping metal ions in g-CN are promising alternatives to traditional homogeneous Fenton catalysts, but are restricted by poor mesoporous structure and agglomerate of metal species. Recently, the highly uniformly dispersed metal-N active sites in various photocatalysts have been proved to be the critical reason for their enhanced catalytic activity. In this study based on reasonable control of mesoporous structure and metal-N active sites, mesoporous Fe-g-CN was synthesized using a simple one-step thermal shrinkage polymerization method using ferrous oxalate as iron source and pore-forming agent.

Sulfur (S) dynamics in soils formed from granite remain poorly understood despite its importance as an essential plant macronutrient and component of soil organic matter. We used stable S isotope ratios to trace the sources and biogeochemical processes of S in four forest soil profiles developed on granite under contrasting climate conditions. The soil S is derived mainly from decomposing litter; no significant geogenic contribution to its content is noted as a result of the low S concentration of the granite (~ 5 μg/g).

Constructing effective interphase boundary is one of the efficient approaches for improving photocatalytic performances of semiconductor materials. In this work, an anatase/rutile-TiO (AR-TiO) heterophase junction with appropriate carbon content was successfully fabricated via an in-situ phase transformation process. The phase transformation started from the inner core of the nanoparticles and the area of phase interface between anatase and rutile was carefully controlled by regulating the activation temperature.

High specific surface area, hierarchical porosity, high conductivity and heteroatoms doping have been considered as the dominating factors of high-performance carbon-based supercapacitors. Inspired by the blue phenomenon of combination of starch and iodine, iodine is employed firstly as pore-making agent to create micropores for the starch-derived carbon in this study. Based on this mechanism, the hierarchically porous carbon is synthesized through simple solvent heating and high-temperature (1000 °C) carbonization, which achieves high specific surface area of 2989 m g (an increase of 39.
