A biosorbent prepared from powdered mycelial biomass of Ceriporia lacerata （CLB）, a basidiomycetous fungus, was applied for the uptake of Crystal Violet from aqueous solution. A batch adsorption experiment was used for the biosorption process, involving effect of experimental factors and biosorption kinetics and equilibrium. Biosorption process showed that the removal of Crystal Violet by CLB was effective over wide pH range, and meanwhile was independent on ionic strength. Biosorption capacities of CLB increased with the initial dye concentration increasing, due to an increase in the driving force of the concentration gradient. The adsorbed Crystal Violet amount per unit biomass weight decreased with increasing biosorbent dosage, due to the splitting effect of flux （concentration gradient） between sorbate and biosorbent. A maximum sorption capacity of 239.25 mg/g was observed. Biosorption kinetics was found to be best represented by the pseudo second-order kinetic model. The equilibrium adsorption data was well described by the Koble-Corrigan model. FT-IR （Fourier Transform Infrared Spetroscopy） spectrum showed the presence of O–H, COOH, C=O, C–N, C–H, –NH2 and P–OH in the surface of CLB as functional groups. This study showed CLB can effectively remove CV from dye wastewater.

ZTE Communications 2024年

An integrated sensing and communication (ISAC) scheme for a millimeter wave (mmWave) multiple-input multiple-output orthogonal frequency division multiplexing (MIMO-OFDM) Vehicle-to-Infrastructure (V2I) system is presented， in which both the access point (AP) and the vehicle equip large antenna arrays and employ hybrid analog and digital beamforming structures to compensate the path loss meanwhile compromise between hardware complexity and system performance. Based on the sparse scattering nature of the mmWave channel， the received signal at the AP is organized to a four-order tensor by the introduced novel frame structure. A CANDECOMP/PARAFAC (CP) decomposition-based method is proposed for time-varying channel parameter extraction， including angles of departure/arrival (AODs/AOAs)， Doppler shift， time delay and path gain. Then leveraging the estimates of channel parameters， a nonlinear weighted least-square problem is proposed to accurately recover the location， heading and velocity of vehicles. Simulation results show that the proposed methods are effective and efficient in time-varying channel estimation as well as vehicle sensing in mmWave MIMO-OFDM V2I systems.
