Preparation and Characterization of Cellulose Nanocrystal Extraction From Pennisetum hydridum Fertilized by Municipal Sewage Sludge via Sulfuric Acid Hydrolysis

open access: yesFrontiers in Energy Research, 2021
This research focuses on the preparation of cellulose nanocrystals (CNCs) from Pennisetum hydridum fertilized by municipal sewage sludge (MSS) through sulfuric acid hydrolysis in different acid concentrations (40–65%), temperature (room temperature ∼55°C)

Beyond Crystallinity: Using Raman Spectroscopic Methods to Further Define Aggregated/Supramolecular Structure of Cellulose

open access: yesFrontiers in Energy Research, 2022
In the bio-based economy, conversion of biomass to biofuels and other products is essential for developing a sustainable alternative to fossil fuels. For this to become a reality, understanding of the biomass ultrastructure is critically important.

Crystalline Nephropathies [PDF]

open access: yesArchives of Pathology & Laboratory Medicine, 2012
Context .—The kidney is a favored site for crystal deposition because of the high concentration of ions and molecules reached at the level of the renal tubules in the course of filtration. This review focuses on crystalline nephropathies in 4 broad categories: (1) dysproteinemia- associated, (2) drug-induced, (3)

Effects of crystallinity control on mechanical properties of 3D-printed short-carbon-fiber-reinforced polyether ether ketone composites

open access: yes, 2021
A change in the crystallinity of short-carbon-fiber-reinforced polyether ether ketone (CF/PEEK) composites has a significant effect on the shrinkage deformation characteristics and mechanical properties of the components that are fabricated using 3D ...

Crystallinity and β Phase Fraction of PVDF in Biaxially Stretched PVDF/PMMA Films

open access: yesPolymers, 2021
Polyvinylidene fluoride (PVDF) and poly(methyl methacrylate) (PMMA) blend films were prepared using biaxial stretching. The effects of PMMA content and stretching ratio on the crystallinity and β phase fraction of PVDF in blend films were investigated ...

Mineral maturity and crystallinity index are distinct characteristics of bone mineral [PDF]

open access: yes, 2010
The purpose of this study was to test the hypothesis that mineral maturity and crystallinity index are two different characteristics of bone mineral. To this end, Fourier transform infrared microspectroscopy (FTIRM) was used.

Utilization of blue crab shells for the synthesis of chitosan nanoparticles and their characterization [PDF]

open access: yesSongklanakarin Journal of Science and Technology (SJST), 2018
Chitosan, a useful biopolymer, was obtained from pulverized shells of blue crabs via demineralization, deproteination and de-acetylation. The chitosan was converted to nanoparticles using sodium tripolyphosphate (TPP).
