Efective processing and use of coal slime is of great signifcance to protect the environment and save resources. Diferent coal slimes (untreated with 43 wt% ash content, crushed and fotation treated with 10 wt% ash content, and pre-carbonized) were activated with KOH to prepare porous activated carbon. The results show the activated carbon prepared from coal slime with 10 wt% ash had high specifc surface area (3037 m2 /g) and pore volume (1.66 cm3 /g), which was ascribed to the suitable contents of minerals as template and oxygen-containing functional groups. Electrochemical measurements exhibited the best specifc capacitance of 220 F/g at 0.1 A/g and the cycle stability of over 100% capacitance retention after 1000 cycles at 5 A/g in 6 M KOH solution. Due to the high specifc surface area, superior electrochemical performance, and facile and low cost, developing highly porous activated carbon for supercapacitors is one alternative way for efective use of coal slime waste.

Background/Aims: Epstein-Barr virus-associated gastric cancers (EBVaGCs) have unique molecular and clinicopathological characteristics. The cyclic GMP-AMP synthase-stimulator of interferon genes (STING) pathway is recently recognized as the critical innate immunity against pathogens and tumors. STING is also a master regulator in the cancer-immunity cycle and tar geting STING could synergize with existing immune-checkpoint therapies. However, the role of STING in GC, especially in EBVaGC, and its correlation with programmed death-ligand 1 (PD-L1) remain largely unclear. Methods: We collected 78 cases of EBVaGCs and 210 cases of EBV-negative GC (EBVnGC) from a total of 1,443 cases of GC analyzed by EBV-encoded small RNA in situ hybridization. We investigated STING and PD-L1 expression and their concomitant prognostic value in EBVaGCs and EBVnGCs using tissue microarray and immunohistochemistry. The effects of STING and PD-L1 expression on the overall survival of patients with EBVaGC or EBVnGC were assessed by univariate and multivariate analysis. Results: We found that both STING and PD-L1 exhibited significantly higher expression in the EBVaGCs than that in the EBVnGCs. The expression of STING was positively correlated with that of PD-L1 in EBVaGCs. Simultaneous negative expression of STING and PD-L1, and posi tive expression of STING were independent prognostic risk factors for EBVaGC and EBVnGC, respectively. Conclusions: This is the first prognostic retrospective study of STING and PD-L1 expression and the prognosis among EBVaGC and EBVnGC. The expression and prognostic value of STING and PD-L1 are different in the two types of GCs. STING and PD-L1 are promising prog nostic biomarkers and therapeutic targets for EBVaGC and EBVnGC.

Thermal interface materials with high thermal conductivity are the best choice to solve the current overheating problem of electronic devices, and the choice of thermal conductive fi ller is a key factor aff ecting the performance of thermal interface composites. Hexagonal boron nitride sheet is considered to be ideal thermal conductive fi ller, but the thermal conductive eff ect of single fi ller is still insuffi cient to meet actual needs. Here, a new type of hybrid fi ller mixed with boron nitride sheet and boron phosphide particles is used to prepare epoxy based composites. When the fi ller volume fraction is 40%, the thermal conductivity of composites reaches 3.18 W m −1 K −1 . Under the same content, the thermal conductivity of the composites with mixed fi llers outperforms those with boron nitride sheet alone. At the same time, the composite material shows high breakdown strength of 46 kV mm −1 . This work provides a new way to prepare thermal interface materials with high thermal conductivity for modern electronic packaging.
