Selective depressant plays an important role in mineral flotation. In this work, a low molecular weight carboxylated starch (LMWCS) was prepared as the selective depress ant for the separation of forsterite and ilmenite by flotation. Flotation behaviors and adsorption mechanisms were...

Facing the serious environmental problem caused by water pollution, it is still challenging to develop a kind of acidic wastewater treatment adsorbent with high adsorption efficiency. In this study, the negative charged cellulose nanofibrils (CNF) were used to enhance the acid-resistance of the...

Mg(NH2)2 -2LiH is one of the most promising hydrogen storage systems to be applied in hydrogen powered vehicles as hydrogen source. However, the synthesis of the main raw material Mg(NH2)2 is high-cost and time-consuming for the present technologies. Herein, we report a low-cost, time-saving and...

Dielectric capacitors show great potential in superior energy storage devices. But the energy density of these capacitors still inadequate for the requirement of energy storage applications. Herein, the Bi0.5Na0.47Li0.03TiO3 -xNaNbO3 (BNLT-xNN) ceramics were prepared via conventional solid phase...

How do online platforms contribute to inclusive growth policies? In this study, we examine how the East-West Poverty Alleviation Partnership, which pairs rich cities in East China with economically disadvantaged cities in West China, affects e-commerce trade. Using proprietary trade-flow data...

Purpose Scattered parts are laid randomly during the manufacturing process and have difficulty to recognize and manipulate. This study aims to complete the grasp of the scattered parts by a manipulator with a camera and learning method. Design/methodology/approach In this paper, a cascaded...
