Flow boiling in microchannels offers a promising and attractive solution for thermal management of electronic devices and power systems. In this paper, microchannels composed of a hydrophilic surface with hydrophobic dots were studied to characterize the effects of non-wetting fraction and pitch...

Recently, semiconductor-based photocatalysis has been witnessed as an alternative technology for many frontier fields. Among the plenty of heterostructures, constructing type II heterojunctions with two or more semiconductors are deemed as efficient strategy for realizing the directional...

Cu2O is one of the few transition metal oxides which can exhibit p–type conductivity due to native acceptor defects. Further improvements in p–type conductivity of Cu2O can be achieved via extrinsic doping and post–growth processing. In this work, we investigate the effects of Ni doping in...

Analyzing and modelling the relationship between particle size and size distribution of engineered nanoparticles (NPs) in vivo represents an important challenge to properly assess the environmental fate and effects of NPs. This study used single-particle ICP-MS to investigate how three sizes of...

The behavior and toxicity of nanoparticles (NPs) could be affected significantly by the ubiquitous natural organic matter (NOM) in aquatic environments. However, the influence of NOM on NPs along the food chain remains largely unknown. This study constructed bacteria Escherichia coli (E. coli)...

Solar water splitting is an eco-friendly technology to produce clean energy, but the water oxidation half reaction hinders the overall water splitting due to four electron transfer processes. Z-Scheme photocatalytic system could effectively promote the separation of photogenerated carriers and...

The electrocatalysis nitrogen reduction reaction (NRR) has been accepted as a sustainable method for N 2 fixation. However, N 2 adsorption and the cleavage of triple bond in N 2 molecules are the main challenges for the NRR. In this work, an I - assisted one-step hydrothermal method was...

Doping the carbon-free fuel NH 3 into pulverized coal furnaces is a feasible approach for reducing CO 2 emissions during thermal power generation, but the NH 3 co-combustion increases NO x emissions. Therefore, it is necessary to study the formation mechanism of NO during the NH 3 -pulverized...

A surface modification through multiple micro shot peening have been performed on Mg-steel components. Application of shot peening was found favorable to the elimination of surface micro defects owing to severe surface plastic deformation induced by shot peening. Besides, multiple shot peening...
