Abstract Recent years have witnessed growing applications of the molecular imprinting technique for detection pesticide residues in environmental and food samples. In this study, molecularly imprinted polymers (MIPs) pyrethroids, a class popular insecticides, were synthesized by crosslinking β‐cyclodextrin (β‐CD) with 1,6‐hexamethylene diisocyanate (HMDI) or toluene‐2,4‐diisocyanate (TDI) dimethyl sulfoxide, lambda‐cyhalothrin (LCT) as model template. Equilibrium batch‐rebinding tests...

Attapulgite (denoted as APT, also called palygorskite) has been regarded the green material in "21st century world" and attracted widespread attention due to its advantages of low cost, natural abundance, nontoxic nature, environmental friendliness. However, limited adsorption sites surface charges APT greatly hinder application an adsorbent industrial fields. In this work, was modified with sodium humate (SA) via a facile one-step hydrothermal process improve capacity systematically studied...

Abstract Cyperus iria is an aggressive weed of rice throughout the world. Until now, reference genome C. has not been published. Here, we completed chromosome-level assembly based on Illumina, PacBio and Hi-C reads. The assembled size was 479.08 Mb with a contig N50 7.02 Mb. 68 pseudochromosomes were produced using scaffolding, accounting for 99.65% genome. number predicted protein-coding genes 47,395, which 93.26% annotated, 37.69% repetitive sequences identified. Our study provided...

Abstract The pyruvate dehydrogenase complex (PDH) critically regulates carbohydrate metabolism. Phosphorylation of PDH by one the kinases 1–4 (PDK1–4) decreases flux carbohydrates into TCA cycle. Inhibition PDKs increases oxidative metabolism carbohydrates, so targeting has emerged as an important therapeutic approach to manage various metabolic diseases. Therefore, it is highly desirable begin establish imaging tools for noninvasive measurements in rodent models. In this study, we used...

Abstract SCMNPs@Uridine/Zn is utilized as an environmental-friendly and efficient heterogeneous nanocatalyst for two one-pot four-component condensation reactions, containing hydrazine hydrate, arylaldehyde, ethyl acetoacetate, barbituric acid to yield tricyclic fused pyrazolopyranopyrimidine derivatives (5a-q), malononitrile, dimethyl acetylenedicarboxylate/diethyl acetylenedicarboxylate 3-methyl carboxylate substituted pyrano[2,3- c ]pyrazole (8a-y) under solvent-free conditions with high...

A novel poly(ionic liquid) adsorbent (PIL-APIBCl) exhibits a high adsorption capacity of 236.68 mg g⁻¹ for Au(<sc>iii</sc>).

Hydrophilic ionic liquid (imidazolium chloride, imCl)–polyvinyl chloride ionomer (imCl–PVC) as a green sorbent to recover precious gold from acidic solution was characterized by SEM, FTIR, XPS and NMR.

Acid red 73 is an azo dye, and its residue can pollute the environment seriously threaten human health life. In this study, glutaraldehyde was used as crosslinking agent, chitosan polyvinyl alcohol were crosslinked under appropriate conditions to obtain a hydrogel film, carbon nanotubes dispersed in film. The FTIR, XRD, BET, SEM applied chatacterize structure morphology of absorbent results showed that when mass fraction 1%, three-dimensional network with microporous, water absorption...

The pseudo‐first‐order pseudo‐second‐order models are to fit adsorption data in kinetic studies results show good correlation with model. Langmuir model found isotherm all rare earth ions (RE ) maximum capacity hydrolyzed PSMA 285.79, 301.92, 305.46, 336.65 mg g −1 at 298 K respectively. could be...

NaYF 4 :Yb 3+ (58%),Tm @NaYF @Au composite nanomaterials were designed and synthesized through condition optimization for the quantitative detection catalytic reduction of 4-NP.

Ammannia auriculata Willd. (eared redstem) has become one of the most troublesome weeds in paddy rice China. Resistance to bensulfuron-methyl (BSM) spread extensively this species. Greenhouse and field experiments were conducted determine how eared redstem biotype density affect competition against rice. In greenhouse experiment, five treatments tested: a BSM-susceptible at low (58 plants m−2, SL), high (288 SH), BSM-resistant (RL), (RH), control without (CK). Eared grew slowly until 15 days...

Abstract Acid red 73 is an azo dye, and its residue can pollute the environment seriously threaten human health life.
