Rhodamine B (RhB) is a synthetic organic xanthene dye that harmful to human health. RhB can easily be illegally added food as colorant due its cheap and abundant. This work presents molecularly imprinted (MIP) electrochemical sensor for the determination of by modifying ZIF-67-derived N-doped carbon composite interconnected MWCNTs (NC@MWCNT) MIP on surface glassy electrode. The exhibited excellent performance detection outstanding conductivity NC@MWCNT specific adsorption MIP. Under...

In this study, a simple electrochemical aptasensor for saxitoxin (STX) detection was developed based on short anti-STX aptamer with methylene blue (MB) incorporated at the 3'-end. The immobilized surface of gold electrode and served as recognition element. successfully used highly selective sensitive biosensor STX because selection along excellent electrocatalytical properties MB. With increase dynamic concentration from 1 nM to μM, exhibited sensitivity peak current change 2.92 μA per...

A novel lignocellulosic aerogel, MT-LCA, was successfully prepared from MT by undergoing partial dissolution in an ionic liquid, coagulation water, freezing liquid nitrogen, and subsequent freeze-drying. The MT-LCA preserves its original honeycomb-like porous structure, the newly formed micropores contribute to increased porosity specific surface area. FT-IR analysis reveals that MT, after coagulation, experiences no chemical reactions. However, a change crystalline structure of cellulose is...

Abstract Wood is one of the high‐quality biomass raw materials due to its excellent performance. However, wood cannot be directly processed plastically because rigidity, limiting utilization high added value. This study was conducted develop a novel biocomposite based on flexible delignified (FDW) modified with epoxidized soybean oil (ESO) resin. FDW, as template, obtained by delignification plantation poplar slices poor quality, and then impregnated ESO pre‐polymerized solution formed...

To improve the performance and expand applications of poplar plantation wood, modified veneers based on 1-butyl-3-methylchloride ([Bmim]Cl) were studied. Two groups impregnated in ionic liquid [Bmim]Cl (group C) pure water B), separately. Techniques such as hot pressing-coagulation bath-annealing applied to these two prepare samples. The physical mechanical properties each group tested characterized, using untreated (A) control. ductility thickness variation rate samples C higher than those...

BaFe12-xCrxO19 (x = 0.0, 0.1, 0.2, 0.3, and 0.4) ferrite ceramics were prepared by a sol-gel method using spruce sapwoods as the templates.The materials characterized scanning electron microscopy (SEM), X-ray diffraction (XRD), magnetic property measurement system (MPMS).The maintained multilayer wall structure of sapwoods.All samples presented single-phase magnetoplumbite barium hexaferrite.The saturation magnetization initially increased until it reached maximum value at x 0.2 then...

Two formulations of wood preservative one containing water-dispersible copper naphthenate (CuN) alone and in combination with sodium fluoride (NaF) were used to treat southern pine sapwood blocks determine the effect addition QNS on protection against decay fungi using laboratory soil block tests following AWPA (American Wood Association) standard E10-16 [American Protection Association AWPA-E10. (2016 American Association. (2016) Standard Laboratory Method for Evaluating Decay Resistance...

Based on the previous study of heat-treated wood at 0-3 mm surface layer, this focuses transition thermal modification intensity 160-220 °C poplar from to core layers. The color change was evaluated by CIELAB, and hardness detected via Shore D (HD) pressing ball method (HR); furthermore, FT-IR applied detect degradation components. results show that cell wall components in layer is greater than layers, other inner Surface properties between S0 S1-S5 test surfaces were significantly...

Novel lignocellulosic composite films (LCFs) based on poplar wood flour (PWF) and waste filter paper (WFP) were developed with 1-allyl-3-methylimidazolium chloride ([Amim]Cl) as green solvent. Scanning electron microscopy revealed that the dissolved part acted matrix combined insoluble reinforced LCFs. Under same preparation conditions, there was an increased amount of PWF. The PWF WFP mass ratio a key parameter influenced solubility raw materials. differences in grammage, thickness,...

Due to the high viscosity of pure [Bmim]Cl, PEG was selected be co-solvent form solvent system. The dissolution and plasticization ability PEG-[Bmim]Cl poplar veneer completed with processes such as hot pressing coagulation bath achieve in-situ modification veneers develop an innovative wood composite, which are expected molded. At same time, effects system on properties composites were studied. results showed that both [Bmim]Cl-treated group (B) PEG-treated (C) had a certain degree...

Wood heat treatment is an environmentally friendly method, and the heat-treated wood properties are closely related to thermal modification intensity. This study focuses on 0-3 mm surface layer (SL) of poplar treated at 160~220 °C. The intensity, including color, hardness, chemical component morphological changes SL, was evaluated. findings this research showed that color difference before after (ΔE*1) increased; between up-surface down-surface SL (ΔE*2) also...
