BCN-driven interfacial effect: A novel strategy to remarkably enhance the capacitance of CoO/NiO for supercapacitor.

A BCN/CoO/NiO (BCN/CNOs) hetero-interface was developed to introduce a novel strategy that remarkably enhances the specific capacitance of transition metal oxides (TMOs). The engineered hetero-interface driven by BCN was characterized by plentiful electrons accumulation and effectively increased the specific capacitance of the as-prepared BCN/CNOs electrode to 8533 mF cm at 2 mA cm, obtaining 154 % improvement compared to acid-treated carbon cloth loaded CNOs (ACC/CNOs). DFT theoretical calculations indicated that the BCN-driven interfacial effect primarily accelerates the charge transfer due to charge accumulation at interface between BCN and CNOs.

Point-to-Point Efficient Grafting Improved Compatibility of Boron-Based Fuel-Rich Propellants.

Due to the high mass calorific value, boron powder is widely used in energetic material systems such as solid propellants and ignition powders. Especially, boron powder has very broad application prospects in the field of fuel-rich propellants. However, due to the cross-linking reaction between the boric acid contained on the surface of boron powder and an adhesive called hydroxylated polybutadiene (HTPB), the viscosity of the propellant mixture system increases sharply, which seriously affects the preparation of the propellant.

Sand-Based Economical Micro/Nanocomposite Materials for Diverse Applications.

Sand is one of the most fundamental construction materials that is of significant importance and widely used for making concrete, plasters, and mortars, and also for filling under floor and basements. Sand-derived functional materials, for instance superhydrophobic sand, which can be used to prepare liquid marble, separate oil-water mixtures, and transport liquids, have recently been a highly topical and promising research field. However, such materials are mainly prepared using valuable surface modification agents via complicated procedures that are difficult for mass-production, which restricted their true applications.

Development of Red Exciplex for Efficient OLEDs by Employing a Phosphor as a Component.

Exciplexes are ideal candidates as effective thermally activated delayed fluorescence (TADF) emitters. However, efficient orange and red TADF exciplexes have been reported seldomly, because their significant non-radiative (NR) decay of excited states lead to unavoidable energy loss. Herein, we propose a novel strategy to construct efficient red TADF exciplexes by introducing phosphor as one component.

Rural settlements transition (RST) is one of the most significant indices for understanding the phenomena of rural reconstruction and urban-rural transformation in China. However, a systematic overview of RST is missing, and there is a lack of evidence regarding its characteristics from the internal structure perspectives. In this paper, we systematically explore the RST regarding spatio-temporal change characteristics of internal structure, patterns and impacts on rural environment and development by using practical survey internal land-use data from 2005 to 2015.

Spin relaxation in single-layer graphene with tunable mobility.

Graphene is an attractive material for spintronics due to theoretical predictions of long spin lifetimes arising from low spin-orbit and hyperfine couplings. In experiments, however, spin lifetimes in single-layer graphene (SLG) measured via Hanle effects are much shorter than expected theoretically. Thus, the origin of spin relaxation in SLG is a major issue for graphene spintronics.
