The biotoxicity and chemotherapeutic resistance of cisplatin (CDDP) pose a challenge for tumor therapy. Practically, the change in therapeutic response from to sensitivity are impressive but challenging. To this end, we propose strategy "one stone, three birds" by designing CuPt nanoalloy simultaneously eliminate GSH, relieve hypoxia, promote ROS production effectively reversing platinum (IV) (Pt(IV), (c,c,t-[Pt(NH

A new mechanism of O2 reduction, which follows principles different from those generally accepted for describing ORR reduction on heteroatom-doped carbons, is suggested. It based the ability oxygen to strongly adsorb in narrow hydrophobic pores. In this respect, a cellular vitreous carbon foam–graphene oxide composite was synthesized. The materials were doped with sulfur and nitrogen and/or heat-treated at 950 °C order modify their surface chemistry. resultant samples presented...

3D printing is widely adopted to quickly produce rock mass models with complex structures in batches, improving the consistency and repeatability of physical modeling. It necessary regulate mechanical properties 3D-printed specimens make them proportionally similar natural rocks. This study investigates analogues prepared by furan resin-bonded silica sand particles. The property regulation realized through quantifying its similarity sandstone, so that analogous deformation characteristics...

This work finds that Fe3O4 nanoclusters can rearrange by Gd doping and then self-assemble to a hollow magnetic nanocluster (HMNC), providing larger moments obtain an excellent MRI capability increasing the number of oxygen vacancies in HMNC. The structure makes platinum(IV) prodrugs effectively load into Second, plenty vacancy defects capture molecules, enhance catalytic activity HMNC, promote intracellular ROS generation. On basis this, targeting iRGD-labeled HMNC nanosystem (iHMNCPt-O2) is...

Cemented coal waste backfill material (CCWBM) is developed for backfilling the goaf in mines. As fresh CCWBM slurry generally transported into underground openings through a pipeline, fluidity of becomes one most important properties. Adding superplasticizer considered to improve flow performance without alerting mechanical filling body. The dosage (SP) related cost, thus response surface methodology (RSM) adopted study influence composition on SP when target slump 250 mm. effects fly ash...

Titanium alloys additively manufactured by electron beam melting (EBM) inevitably obtained some pore defects, which significantly reduced the very high cycle fatigue performance. An ultrasonic test was carried out on an EBM TC21 titanium alloy with hot isostatic pressing (HIP) and non-HIP treatment, effect of defects (VHCF) behavior were investigated for alloy. The results showed that S-N curve specimens clearly had a tendency to decrease in regimes, HIP treatment improved properties....
