2017年8月15日 · In this paper, we investigate the surface chemistry of starch adsorbed onto hematite by means of X-ray photoelectron spectroscopy and Fourier transform infrared spectroscopy. Our results indicate that starch undergoes an important oxidation process under industrial gelatinization conditions, which favors the binding of starch molecules.

2022年4月15日 · In this study, we report a top-down approach to fabricate starch nanoplatelets (SNPs) based on a deep eutectic solvent (DES) comprised of choline chloride and oxalic acid dihydrate. When subjecting waxy maize starch (WMS) to 2 h of DES treatment, the SNPs of oxalate half-ester were successfully fabricated.

2024年10月1日 · The XPS was employed to investigate the elemental binding state of SNC and SNC-(1-5) by measuring the chemical state of carbon (C) and oxygen (O) atoms. In Fig. 3 A, the peaks at 531 and 285 eV were attributed to the C and O elements, respectively.

2023年5月1日 · Smooth surface and homogeneous starch nanospheres are prepared using controllable dynamic high-pressure microfluidization with a nanoprecipitation method.

Surface chemical compositions of starch nanocrystals (SNC) prepared using sulfuric acid (H2SO4) and hydrochloric acid (HCl) hydrolysis were analyzed by X-ray photoelectron spectroscopy (XPS)...

5 天之前 · Unless otherwise noted, the starch-based gel samples were prepared by applying 200 µl of BSA solution to 100 mg of MPs for uniform and sufficient wetting. The XPS spectrum of the gel was measured using a K-alpha X-ray photoelectron spectrometer (Thermo Fisher Scientific).

2022年4月18日 · In-depth XPS and AES spectra further confirm the Zn corrosion and by-products generation can be suppressed by starch due to its polyiodide trapping capacity. This systematic study paves a way for designing next-generation Zn–I 2 batteries without a shuttle effect, and provides inspiration for the development of other batteries suffering from ...

The results showed that, with respect to starch particles, PANI/starch biocomposites exhibit an overall decrease in particles size, which improves both their aqueous dispersion and solubility...

2017年8月15日 · The traditional hematite depressant starch has the disadvantages of poor solubility and high viscosity. In this study, a novel hematite depressant, pullulan, with better performance and flotation … Expand
