Functionalization of waterborne polyurethane with rosin and epoxidized soybean oil for high-performance, UV-shielding, and hydrophobic biobased films and cotton coatings

Industrial Crops and Products
The development of high-performance waterborne polyurethane (WPU) from biomass materials represents a significant issue in green industry. In this work, a rosin-based epoxidized soybean oil polyol (RE) was synthesized via a ring-opening reaction between ...

Conditions for Shake-Gel Formation: The Relationship between the Size of Poly(Ethylene Oxide) and the Distance between Silica Particles

Molecules, 2022
Colloidal silica suspensions are widely used in many fields, including environmental restoration, oil drilling, and food and medical industries. To control the rheological property of suspensions, poly(ethylene oxide) (PEO) polymers are often used. Under

Rheological measurement of molecular weight distribution of polymers

e-Polymers, 2013
This paper has described a method to obtain the molecular weight distribution (MWD) of polymeric materials from their rheological data. The method has been developed for linear polymers with log normal molecular weight distribution.

Recovery of the PHA Copolymer P(HB-co-HHx) With Non-halogenated Solvents: Influences on Molecular Weight and HHx-Content

Frontiers in Bioengineering and Biotechnology, 2020
Biodegradable and biocompatible polyhydroxyalkanoates (PHAs) are promising alternatives to conventional plastics. Based on the chain length of their monomers they are classified as short chain length (scl-) or medium chain length (mcl-) PHA polymers. The

Physicochemical and Molecular Properties of Spelt and Wheat Starches Illuminated with UV Light

Applied Sciences, 2023
Scope: Aqueous suspensions of spelt and wheat starch were irradiated with ultraviolet radiation for 5–50 h. The changes in the molecular structure of the starch induced by UV radiation were related to the photodegradation of starch chains and the ...

Influence of Hyaluronic Acid Transitions in Tumor Microenvironment on Glioblastoma Malignancy and Invasive Behavior

Frontiers in Materials, 2018
The extracellular matrix (ECM) is critical in tumor growth and invasive potential of cancer cells. In glioblastoma tumors, some components of the native brain ECM such as hyaluronic acid (HA) have been suggested as key regulators of processes associated ...

European Standard Clinical Practice Guideline and EXPeRT Recommendations for the Diagnosis and Management of Gastroenteropancreatic Neuroendocrine Neoplasms in Children and Adolescents

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Pediatric gastroenteropancreatic neuroendocrine neoplasms (GEP‐NENs) are extremely rare and clinically heterogeneous. Management has largely been extrapolated from adult practice. This European Standard Clinical Practice Guideline (ESCP), developed by the EXPeRT network in collaboration with adult NEN experts, provides (adult) evidence ...

Dynamic Wetting of Molten Polymers on Cellulosic Substrates: Model Prediction for Total and Partial Wetting

Frontiers in Materials, 2020
This work consists in an experimental investigation of forced dynamic wetting of molten polymers on cellulosic substrates and an estimation of models describing this dynamic. A previous work of Pucci et al. (2018) showed that for totally wetting liquids (

Effect of Degumming Methods on Structure and Properties of Regenerated Antheraea Pernyi Silk Fibroin Films

Journal of Natural Fibers, 2022
The extraction of fibroin (degumming) from the silk fibers impacts the properties of silk fibroin. However, the effect of the degumming method on structures and properties of regenerated Antheraea pernyi silk fibroin (ASF) biomaterials has not been ...
