“…The resultso ft hermogravimetric analysis( TGA) and differential thermala nalysis (DTA) of FS ( Figure S4) reveal that the FS undergoes at hree-stage thermal decomposition process.T he first two stages (17.9-130.03 and 130.03-296.29 8C) were attributed to the loss of moisture in the sample. The third stage (296-647.37 8C) was attributed to the decomposition of PAM and SH, [27] and the decomposition temperature was higher than that reported previously. [28] These resultsi ndicate that SH and PAMc ombined successfully with ATPt of orm the FS and that the SH and PAMi nF Sp ossessedh ighert hermals tabilities than SH or PAMa lone.…”

Urea tends to be hydrolyzed by urease and then migrate into the environment, which results in a low utilization efficiency and severe environmental contamination. To solve this problem, a network-structured nanocomposite (sodium humate-attapulgite-polyacrylamide) was fabricated and used as an excellent fertilizer synergist (FS) that could effectively inhibit the hydrolysis, reduce the loss, and enhance the utilization efficiency of nitrogen. Additionally, the FS exerted significant positive effects on the expression of several nitrogen-uptake-related genes, ion flux in maize roots, the growth of crops, and the organic matter in soil. The FS could modify the microbial community in the soil and increase the number of bacteria involved in nitrogen metabolism, organic matter degradation, the iron cycle, and photosynthesis. Importantly, this technology displayed a high biosafety and has a great potential to reduce nonpoint agricultural pollution. Therefore, this work provides a promising approach to manage nitrogen and to promote the sustainable development of agriculture and the environment.

Summary An efficient intrinsic flame retardants composite was prepared by curing epoxy resin with a functional magnesium organic composite salt (FMOCS, 0.685 ± 0.3 nm) and diethylenetriamine (DETA). Curing behavior, thermal and flame‐retardant properties of the cured epoxy resins were systematically investigated by infrared spectrum (FTIR), thermogravimetric analysis (TGA), vertical burning test (UL‐94) and limited oxygen index (LOI) measurement. It was found that flame retardancy and mechanical properties of the cured composite are significantly enhanced compared with DETA/EP. The LOI of the EP reached to 33%, which is much higher than the DETA/EP (19%) or its IFR composite (31%) in the optimal addition of ammonium polyphosphate (APP, 18.69 wt %), pentaerythritol (PER, 6.21 wt %) and FMOCS (3.50 wt %). Furthermore, the mechanical properties of the composite material measurement results to imply that it can enhance tensile strength (150%) and bending strength (88%) rather than DETA/EP, which were tested by impact testing machine and microcomputer control electron universal testing machines.

Improved properties by hydrogen bonding interaction of poly(lactic acid)/palygorskite nanocomposites for agricultural products packaging

Poly(lactic acid) (PLA)/palygorskite (PA) nanocomposites were fabricated through melt blending. The significant finding by Fourier transformed infrared spectra and X‐ray photoelectron spectroscopy was that the hydrogen bonding interaction between PA surface and PLA matrix. Due to the hydrogen bonding interaction, the PA particles could be well dispersed and distributed in the PLA matrix, which had been further confirmed by scanning electron microscopy and transmission electron microscopy results. Therefore, PLA/PA nanocomposites revealed the significant improvements in tensile properties, resulting in the potential application for agricultural products packaging. Due to PA aggregates, the degree of hydrogen bonding decreased with the increasing content of PA in the matrix, and the appropriate PA content is 3% (by weight). POLYM.
