Cryogenic LN2 fracturing is one of the environmentally friendly waterless fracturing technologies that promote the fracture complexity of shale gas reservoir.The water-ice phase transition under freezing condition causes frost heave in saturated shale.The effect of moisture in shale should be taken into account during cryogenic damage process.There
The most common method of cancer treatment still includes surgical treatment, which is also the oldest way to fight cancer.Radiotherapy is currently one of the basic method of treating malignant tumors [1].This method uses the action of ionizing radiation.However, the radiation does not work selectively and also damages healthy tissues.Chemotherapy

Nanotechnology has gained tremendous attention because of its crucial characteristics and wide biomedical applications.Although zinc oxide nanoparticles (ZnO-NPs) are involved in many industrial applications, researchers pay more attention to their toxic effects on living organisms.Since the olfactory epithelium is exposed to the external environme
The MnOx/Al2O3 catalysts with different Ce content doping were prepared by an ultrasonic impregnation method, and the catalytic activity for NO oxidation removal was tested in a fixed-bed quartz tube furnace.Simultaneously, the catalysts were characterized by X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), full-automatic physical-c
