A latent heat thermal energy storage (LHTES) system, which uses phase change materials (PCMs) as thermal storage medium, has attracted interests over the past decades due to its high energy storage density. However, a computationally efficient heat transfer model, which is essential for...

The efficient removal of arsenic from wastewater is still a challenge. In this paper, a heterojunction consisted of in-situ carbon-doped TiO2 and nitrogen deficiency g-C3N4 (C/TiO2@ND-C3N4) has been constructed, which can completely oxidize As(III) (10,000 μg/L, 40 mL) to As(V) within 12 min...

Controlling the shape, morphology, and porosity of hollow nanostructures is a pivotal issue for adjusting the characteristics of tailor-made nanomaterials to expand their application to more fields. Although many hollow metal oxides have been developed, studies on the construction of hollow...

Improper operating temperature will degrade the performances of electronic components, Li-ion batteries and photovoltaic (PV) cells, which calls for a good thermal management system. In this paper, specific attention is paid to the thermal management systems based on the phase change materials...

We test the determinants of low intra-industrial technology spillovers of foreign direct investment in China’s manufacturing industries with the quantile regression method. Greater technology gap, fewer state-owned enterprises and large-and-medium-size enterprises, and greater industrial...

An opposed-piston hydraulic free piston engine operating with homogenous charge compression ignition (HCCI) combustion, has been proposed by State Key Laboratory of Engines as a means of significantly improving the IC engine’s cycle thermal efficiency and lowering exhaust emissions. Single and...
