A three-electrode system composed of TiO2/Ni as the working electrode, porous nickel counter and saturated calomel electrode (SCE) reference was used for photoelectrocatalytic degradation organic compounds. The sulfosalicylic acid (SSal) under anodic bias potential investigated. It is shown that SSal can be degraded effectively external increased up to 700 mV (vs SCE). characteristics by electrochemical impedance spectroscopy (EIS) also from EIS appears a simple reaction on surface,...
A parametric array loudspeaker (PAL) generates a highly directional audible sound beam. However, indoor scattering and reflecting effects diminish its advantage of high directivity, causing the scattered or reflected to appear in undesired regions. Deriving from Westervelt equation, nonlinear coupling exists between each channel, rendering linear field control algorithms ineffective. This paper proposes framework control, enabling manipulation fields generated by PAL complicated acoustic...
Parametric array loudspeakers (PALs) produce highly directional sounds due to the parametric process in air. Its application creating personal audio zones requires simple modeling of audible sound field near PAL, which is crucial for subsequent designs reduce inherent nonlinear distortion. However, current accurate methods describing field, reliant on numerical solutions wave equations, are computationally intensive. To achieve both effectiveness and simplicity, this paper proposes a...
This paper describes a method for focusing the reproduced sound in bright zone without disturbing other people dark personal audio systems. The proposed combines least-squares and acoustic contrast criteria. A constrained parameter is introduced to tune balance between two performance indices, namely, spatial average error. An efficient implementation of this using convex optimization presented. Offline simulations real-time experiments linear loudspeaker array are conducted evaluate...
This study performed a laboratory investigation of applying high percentage reclaimed asphalt pavement (RAP, up to 50%) in an mixture. The properties aged binder were first determined and the rejuvenator SBR latex used restore properties. optimum dosages additive are 2% 4% mass, respectively. Then preheating temperatures aggregate according RAP content meet mixture temperature requirement. effects blending process, especially feeding sequence materials, on performances investigated recommend...
Current chemo/biosensors for hypochlorous acid or hypochlorite detections are usually limited to the submicromolar level because of their insufficient sensitivity, which is a problem concentrations in biological matrices generally on nanomolar scale even lower. Developing probe with high enough sensitivity remains challenge. Using minimal background fluorescence upconversion nanocrystals our advantage, we herein report an energy-transfer mechanism-based luminescent nanosensor sensitive and...
A substrate integrated waveguide multibeam antenna fed by a double-fold 7×8 Butler matrix (BM) beam-forming network (BFN) is presented. The proposed composed of BM feeding and an 8×8 slot array. By merging the two central input ports into one port, can provide output signals with equal phase, which generate boresight beam. In order to reduce size antenna, folded twice three-layer structure. Measured results show that has impedance bandwidth 29.5 ∼ 30.5 GHz, whereas gain lies in range...
Although microplastics (MPs) toxicity to soil microorganisms has been preliminarily explored, the underlying reasons affecting direction of microbial community succession are unclear. This study aimed investigate impacts MPs infer assembly mechanisms through phylogenetic bin-based null model analysis, network models, and protein function prediction in five typical Northeast China soils. The results show that communities soils with high organic matter exhibit a stronger response MPs, enhanced...
This study aims to investigate factors influencing dental arch development in patients aged 0-6 years with cleft palate after Sommerlad-Furlow (SF) palatoplasty. A total of 183 who underwent primary SF repair for lip and before 18 months age were included. Follow-ups conducted at different ages, digital casts the maxillary obtained using 3-matic Research 12.0 software. The length width measured explore developmental changes procedure. also investigated influence gender, age, type, relaxation...
Abstract Multicompartment micelles (MCPs), comprising sequences of repeated elemental discoid parts connected by fasciculus, were formed self‐assembly polystyrene‐ block ‐poly(2‐vinyl pyridine)‐ ‐poly(ethylene oxide). Using an electrostatic field, the MCPs can be disassembled through consequent release small spherical micelles. During this disassembly process, loaded species achieved from in chronological order. Two location‐selected cargos (mitoxantrone (MTNT) and fluorescein isothiocyanate...
We study the evolution of temporal properties MAXI 1820+070 during 2018 outburst in its hard state from MJD 58190 to 58289 with Insight-HXMT a broad energy band 1-150 keV. find different behaviors hardness ratio, fractional rms and time lag before after 58257, suggesting transition occurred at around this point. The observed lags between soft photons 1-5 keV higher bands, up 150 keV, are frequency-dependent: low-frequency range, 2-10 mHz, both timescale dozens seconds but without clear trend...
