Summary: Zn2SnO4(ZTO)/ZIF-8 nanocomposite photocatalysts were prepared using solution method and hydrothermal method. The addition of ZIF-8 improved the photocatalytic activity of ZTO by inhibiting the recombination of photoelectron-hole pairs. The composite exhibited slightly improved adsorption performance due to the high specific surface area of ZIF-8. With 0.4 wt%ZIF-8, the ZTO nanocomposite achieved a photocatalytic activity of 75% in the removal of 20 mg/L MB dye solution after 120 min.

Summary: In this study, a hybrid heterostructure composite electrode material made of transition metal oxide (NiO) and metal dichalcogenide (MoS2) was prepared using a hydrothermal process. This heterostructure composite exhibited significantly improved specific capacitance compared to pure NiO and MoS2 materials. The combination of transition metal oxide and metal dichalcogenide effectively supported the pseudocapacitive performance, greatly improving ion transport and storage within the material. After 2000 cycles, the prepared heterostructure composite electrode material retained 101% of its initial capacitance. This finding opens up a new avenue for the quickly increasing field of heterostructure materials.

CNF with SiO2 facilitated the formation of a CoO-NiO coating with a stacked petal structure, while nano-SiO2 acted as an anchor between NiO-CoO and CNF, enhancing the binding. NiCo@Si1-C exhibited a specific capacitance of 518.1 F g-1 at 0.5 A g-1, 2.25 times that of NiCo@Si0-C. It also showed a low capacitance decrease of 3.9% at a high current density of 50 A g-1, indicating excellent rate performance. Furthermore, an asymmetric supercapacitor device (NiCo@Si1-C//AC) achieved an energy density of 11.7 Wh kg -1 and a high power density of 14,000.7 W kg -1.

Summary: In this study, nano-cube ceria was synthesized through a hydrothermal method, and ultrafine ruthenium nanoparticles were loaded on the surface of nano-cube ceria to prepare two different catalysts. The ruthenium nanoparticles were uniformly dispersed on the ceria support, providing a strong metal-support interaction. The Ru/CeO2-H2/Ar catalyst showed high catalytic activity and relatively low activation energy for the hydrolytic dehydrogenation of ammonia-borane, and retained about 65.8% of its catalytic activity after five consecutive tests. This work presents a general strategy for achieving high-performance supported catalysts with ultrafine metal nanoparticles in a uniform distribution.

Summary: In this study, sodium fluotitanate (Na2TiF6) was introduced into MgH2 through ball milling to enhance its hydrogen storage performance. The in-situ generated TiH2, MgF2, NaMgH3, and TiF4 catalytically active species can realize the regulation of kinetic and thermodynamic properties, leading to improved hydrogen storage properties. The starting hydrogen release temperature of MgH2-NTF-10 was significantly decreased to 226 degrees C, and about 6.1 wt% of hydrogen can be released at 300 degrees C in only 30 min. The reversible hydrogen storage performance of MgH2-NTF-10 after ten cycles showed 95% hydrogen storage capacity retention. The synergistic functions of multiphase active components from NTF additive may advance MgH2 further to practical applications.

Summary: This study investigated the changes in serum lncRNA MIR17HG levels in multiple myeloma (MM) patients and its value in assessing MM diagnosis accuracy and prognosis prediction. The results showed that serum MIR17HG levels were up-regulated in MM patients and increased with the progression of DS and ISS stages. Serum MIR17HG was positively correlated with Scr and LDH, and negatively correlated with ALB in MM patients. A serum MIR17HG level >1.485 could evaluate the accuracy of MM diagnosis. High serum MIR17HG level was associated with significantly shortened PFS and OS in MM patients.
