The crystallinity degree influence on the weather resistance of CF/PPS composites
Polyphenylene sulphide (PPS) is a semi-crystalline high-performance thermoplastic used in the aeronautic field as a composite usually reinforced with carbon fibers. The crystallinity of semi-crystalline thermoplastics can ...
Correlation between degree of crystallinity, morphology and mechanical properties of PPS/carbon fiber laminates
The crystallization degree in semi-crystalline thermoplastics plays an important role in determining the final properties of structural composite material (e.g. Toughness, stiffness and solvent resistance). The main purpose ...
Effect of crystallinity on CF/PPS performance under weather exposure: Moisture, salt fog and UV radiation
The crystalline content of a composite can affect its performance under environmental conditions. The objective of this study is to evaluate the influence of the crystallinity degree of CF/PPS composites to hygrothermal, ...
Influence of pretreatment severity on structural changes, lignin content and enzymatic hydrolysis of sugarcane bagasse samples
The structural changes, lignin content and enzymatic hydrolysis of dilute acid pretreated bagasse from 19 varieties of sugarcane were investigated. Chemical compositions varied significantly between the materials. Glucose ...
Structural characterization and in vivo evaluation of retinyl palmitate in non-ionic lamellar liquid crystalline system
(Elsevier B.V., 2011-07-01)
Carrier systems for lipophilic drugs, such as the liquid crystalline systems (LCS) have been extensively studied to improve effect and selectivity. Retinyl palmitate (RP) is widely used in pharmaceutical and cosmetics ...
Synthesis and Characterization of Novel, Highly Crystalline Poly(vinyl alcohol) Microspheres for Chemoembolization Therapy
Biodegradable polymeric microspheres can be used to deliver drugs through controlled rate and targeted processes. The drug is released from the particles by drug leaching or degradation of the polymeric matrix. Crystallinity ...
Morphometric and crystallinity changes on jicama starch (Pachyrizus erosus) during gelatinization and their relation with in vitro glycemic index
(Wiley VCH Verlag, 2017-07)
The effect of gelatinization on the in vitro glycemic index (GI) of starch obtained from jicama tubers was investigated, and the relationships between the starch crystallinity, granule morphology, and the GI were measured. ...
The effect of cyclic voltammetry on the crystalline order of PdPc thin films

Luminescence in semi-crystalline zirconium titanate doped with lanthanum
(Elsevier B.V., 2006-10-25)
This paper aims to describe the synthesis of the semi-crystalline and crystalline powder of lanthanum doped with zirconium titanate (65/35), LZT through Pechini method. The analysis done by Raman demonstrated that ...
Melt behaviour, crystallinity and morphology of poly(p-dioxanone)
