A Coherent PMI Estimation Scheme for Double Codebook
The double codebook structures are proposed and applied in LTE-advanced, which can track both longterm and short-term channel state information. In traditional incoherent estimation, precoding matrix indicators (PMI) estimation is performed on each individual subcarrier and some form of averaging procedure then follows to combine the results from individual narrow-band processing. As a result, …

Facile synthesis of activated carbon/carbon nanotubes compound for supercapac…
a b s t r a c t A large number of carbon nanotubes (CNTs) have been produced commingled in activated mesocarbon microbeads (AMCMBs) activated by potassium hydroxide in a stainless steel container at 900 ◦C, in which an especial buried-protection method with petroleum coke powders was used to protecting the product during activation. The CNTs were found to be about 50nmin diameter and char…

Highly enhanced capacitance of CuO nanosheets by formation of CuO/SWCNT netwo…
Abstract. A series of uniform composite networks consisting of CuO nanosheets (NSs)/single-wall carbon nanotubes (SWCNT) were fabricated through a facile and green method with the aid of electrostatic interaction in aqueous solution. The capacitance was investigated by using various electrochemical methods including cyclic voltammetry (CV), constant-current galvanostatic charge/discharge cu…

Kinetic parameters and mechanisms of the batch biosorption of Cr(VI) and Cr(I…
Abstract. The hyperaccumulative plant species Leersia hexandra Swartz, particularly, has been considered for its detoxification mechanism for phytoremediation of chromium-contaminated water environments. This study investigates the role of the adsorption mechanism of the L. hexandra Sw. biomass on the removal of chromium ions Cr(VI) and Cr(III) from an aqueous solution. The interaction betw…

Fabrication of robust honeycomb polymer films: A facile photochemical cross-l…
Abstract. Highly ordered honeycomb films are prepared by breath-figure method using an amphiphilic diblock copolymer of polystyrene-block-polyacrylic acid (PS-b-PAA). By simply cross-linking PS matrix via deep ultraviolet (UV) irradiation, both the solvent and thermal stability of the porous films was significantly improved while retaining the three-dimensional (3D) structures. The film sur…

Sustainable production of acrolein: Preparation and characterization of zirco…
Abstract ZrO2-supported H3PW12O40 (HPW) catalysts were used to catalyze the dehydration of glycerol to produce acrolein at 315 8C under a high space velocity (GHSVGlycerol = 400 h1). The catalysts were prepared by varying the loading of HPW on two ZrO(OH)2 supports of different preparations, followed by calcination in flowing nitrogen. The use of alcogel-derived ZrO(OH)2-AN for the support…

Effect of La2O3 on Ru/CeO2-La2O3 Catalyst for Ammonia Synthesis
Abstract A series of CeO2-La2O3 supported ruthenium catalysts were prepared by co-precipitation method and the as-obtained samples were characterized by N2 physisorption, X-ray diffraction, CO chemisorption, H2-TPR, H2- TPD and XPS. The activity test shows that ammonia concentration of the catalyst with 10% La is 13.9% at 10 MPa, 10,000 h-1, 450 C, which is 17% higher than that of Ru/CeO2…

A triple fluorescent compound, N-salicylidene-3-hydroxy-4-(benzo[d]thiazol-2-yl)phenylamine (SalHBP), was dispersed in solid polymers and was developed as a white-light-emitting source in LED by using it as the first simple single compound with different configurations. The CIE coordinates were at (0.29, 0.35), close to those of pure white light. To explore speciation mechanisms in this sing…

Novel Thrombo-Resistant Coating Based on Iron-Polysaccharide Complex Multilayers
ABSTRACT The biocompatibility of iron-polysaccharide complexes has been well-documented. Herein, a stable thrombo-resistant coating was fabricated by consecutive adsorption of Fe (III) and polysaccharides including heparin (Hep) and dextran sulfate (DS) onto various surface by layer-by-layer self-assembly technique via both electrostatic interaction and chemical complexation process. The abso…

Effect of biochar amendment on soil-silicon availability and rice uptake
Rice growth and its resistance to pests had been often constrained by soil-silicon (Si) availability.The purpose of this study was to assess the potential of biochar soil amendment (BSA) to improve Si availability in paddy soils. A cross-site field trail with BSA was conducted in six locations with different climatic and crop-production conditions across S China. Plant-available Si content befo…
