Flow characteristics and gelatinization kinetics of rice starch under strong alkali conditions [PDF]

open access: yesarXiv, 2004
The normality dependence and the kinetics of flow behavior in the rice starch dispersion under strong alkali conditions were studied. Non-Newtonian flow (power-law) quantities n and \mu (\sigma=\mu(\dot\epsilon)^n; \sigma: shear stress, \dot\epsilon: shear rate) of the samples stored (gelatinized) at 20^{\circ}C for 10min after the addition of NaOH ...

How Does Cultural and Colonial Heritage Affect Optimal Branding Strategies? Evidence From the Rice Sector in Senegal

open access: yesAgribusiness, EarlyView.
ABSTRACT Africa's cultural and colonial heritage has profoundly segmented rice markets. Whereas in ancient centers of rice domestication, consumers maintained preferences for local rice consistent with their cultural heritage, preferences have shifted toward imported Asian rice in coastal areas around seaports, due to prior exposure to colonial import ...

Controlled Catalysis Delivering High Molecular Weight Polyesters as Recyclable Alternatives to Polystyrenes

open access: yesAngewandte Chemie, EarlyView.
This work exemplifies how to make high molar mass ring opening copolymerization (ROCOP) polyesters as engineering plastics, informing upon their thermal and mechanical properties. Leading polyesters, prepared by epoxide/anhydride ROCOP, show high glass transition temperatures and tensile and flexural strengths, matching or exceeding polystyrene ...

Nationwide medical database study for postoperative nutritional management in patients undergoing gastroenterological cancer surgery

open access: yesAnnals of Gastroenterological Surgery, EarlyView.
The study aim was to clarify how nutrition was managed in patients based on surgical site during the first 7 d after gastrointestinal cancer surgery. As results, oral intake after gastrointestinal cancer surgery started earliest in patients having liver surgery and latest in patients having esophageal surgery.

Preparation and electrochemical properties of nitrogen-doped starch hard carbon anode materials for lithium-ion battery [PDF]

open access: yesarXiv
Here, we report the synthesis of hard carbon materials(CSH) made from corn starch and their application as an anode in lithium-ion batteries. The study shows that the Microstructure and electrochemical properties of CSHs are affected by nitrogen doping. It is found that nitrogen is embedded in the carbon layer with graphite nitrogen, pyridine nitrogen,

Hydrogel‐Based Smart Materials for Wound Healing and Sensing

open access: yesAggregate, EarlyView.
The graphical abstract illustrates the role of hydrogel‐based flexible materials in advancing biomedical applications, including wound healing, point‐of‐care diagnostics, smart patches, and wearable devices. Hydrogels are particularly promising in modern wound care due to their high‐water content, flexibility, and biocompatibility.
