Abstract

Highly sulfonated carbonaceous spheres with diameter of 100–500 nm can be generated by hydrothermal carbonization of glucose in the presence of hydroxyethylsulfonic acid and acrylic acid at 180 °C for 4 h. The acidity of the prepared carbonaceous sphere C4-SO{sub 3}H can reach 2.10 mmol/g. It was used as a solid acid catalyst for the hydrolysis of cornstarch. Total reducing sugar (TRS) concentration of 19.91 mg/mL could be obtained by hydrolyzing 20 mg/mL cornstarch at 150 °C for 6 h using C4-SO{sub 3}H as solid acid catalyst. The solid acid catalyst demonstrated good stability that only 9% decrease in TRS concentration was observed after five repeat uses. The as-prepared carbon-based solid acid catalyst can be an environmentally benign replacement for homogeneous catalyst. - Highlights: • Carbon solid acid was successfully prepared by one-step hydrothermal carbonization. • The acrylic acid as monomer was effectively reduce the diameter size of particle. • The solid acid catalyst show good catalytic performance of starch hydrolysis. • The solid acid catalyst is not significantly deteriorated after repeated use.

Fluidized-bed immobilized-enzyme reactor for the hydrolysis of cornstarch to glucose

Journal Article Allen, B; Charles, M; Coughlin, R - Biotechnol. Bioeng.; (United States)

We have developed an economical fluidized-bed immobilized-enzyme cornstarch hydrolysis reactor employing an inexpensive glucoamylase-on-alumina (covalently bonded) catalyst having a high initial activity (130 units/g) and excellent long term stability (t/sub 1/2/ = 6450 hr at 50/sup 0/C). The reactor can give higher yields of dextrose from streams containing approx.30% (wt) low dextrose equivalent (DE) cornstarch than can a comparable fixed-bed reactor because its design exploits the fact that fluidization permits the use of very small catalyst particles (down to 50 ..mu..m in our case) which overcomes the yield-limiting diffusion-associated problems encountered in the use of conventional fixed-bed cornstarch hydrolysis reactors.more »« less

Template free fabrication of hollow hematite spheres via a one-pot polyoxometalate-assisted hydrolysis process

Journal Article Baodong, Mao; Zhenhui, Kang; Chungui, Tian; ... - Journal of Solid State Chemistry

Uniform hollow hematite ({alpha}-Fe{sub 2}O{sub 3}) spheres with diameter of about 600-700 nm and shell thickness lower than 100 nm are obtained by direct hydrothermal treatment of dilute FeCl{sub 3} and tungstophosphoric acid H{sub 3}PW{sub 12}O{sub 40} solution at 180 deg. C. The hollow spheres are composed of robust shells with small nanoparticles standing out of the surface and present a high-surface area and a weak ferromagnetic behavior at room temperature. The effect of concentration of H{sub 3}PW{sub 12}O{sub 40}, reaction time and temperature for the formation of the hollow spheres are investigated in series of experiments.

Improvement of catalytic activity in selective oxidation of styrene with H{sub 2}O{sub 2} over spinel Mg–Cu ferrite hollow spheres in water

Journal Article Tong, Jinhui; Cai, Xiaodong; Wang, Haiyan; ... - Materials Research Bulletin

Graphical abstract: Uniform spinel Mg–Cu ferrite hollow spheres were prepared using carbon spheres as templates. Solid spinel Mg{sub 0.5}Cu{sub 0.5}Fe{sub 2}O{sub 4} ferrite nanocrystals were also prepared by sol–gel auto-combustion, hydrothermal and coprecipitation methods for comparison. The samples were found to be efficient catalysts for oxidation of styrene using hydrogen peroxide as oxidant. Especially, in the case of Mg{sub 0.5}Cu{sub 0.5}Fe{sub 2}O{sub 4} hollow spheres, obvious improvement on catalytic activity was observed and 21.2% of styrene conversion and 75.2% of selectivity for benzaldehyde were obtained at 80 °C for 6 h reaction in water. The catalyst can be magnetically separatedmore »« less

Radiotracers For Lipid Signaling Pathways In Biological Systems

Technical Report Gatley, S.

The primary focus of this project continues to be the development of radiotracers and radiotracer methodology for studying physiology and biochemistry. The compounds that have been labeled areacylethanolamines and acylglycerols that are, as classes, represented in both in plants and in animals. In the latter, some of these act as ligands for cannabinoid receptors and they are therefore known as endocannabinoids. Cannabinoid receptors are not found in plant genomes so that plants must contain other receptors and signaling systems that use acylethanolamines. Relatively little work has been done on that issue, though acylethanolamines do modulate plant growth and stress resistance,more »« less

Effects of cornstarch on the gel properties of black bean protein isolate

Journal Article Xu, Xiu‐Ying; Cao, Yong; Zhang, Hao; ... - Journal of texture studies

Abstract The effects of common starch (CS) and high amylopectin starch (HAS) from corn on the properties of heat induced black bean protein isolate (BBPI) gels prepared by heating at 95°C for 30 min were investigated by using dynamic oscillatory rheometer, texture analyzer, and scanning electron microscopy (SEM). Compared with BBPI alone, the presence of cornstarch (1–4%, wt/vol) could improve storage modulus (G′) and textural properties of BBPI (10%, wt/vol) gels. The mixed system of BBPI and 4% (wt/vol) HAS exhibited the highest G′ and formed the gel faster and more easily, which resulted in firmer and more elastic gel thanmore »« less
