Zirconium Dioxide Supported on .alpha.-Cellulose: Synthesis and Characterization
Langmuir, 1994Cellulose-supported zirconium dioxide was prepared by reaction of ethanolic zirconium tetrachloride solution with a-cellulose. The treated cellulose was characterized by C-13 cross-polarization magic angle spinning nuclear magnetic resonance, powder X-ray diffraction, X-ray photoelectron spectroscopy, scanning electron microscope, and X-ray ...

MWNT reinforced melamine-formaldehyde containing alpha-cellulose
Composites Science and Technology, 2007Multi-wall carbon nanotubes (MWNT) were used as reinforcement for melamine-formaldehyde (MF). They were oxidised in HNO3/ H2SO4 mixture and analyzed by means of X-ray Photoelectron Spectroscopy (XPS). Two anionic surfactants: sodium dodecyl sulphate (SDS) and sodium dodecylbenzenesulfonate (NaDDBS) were used to assist the dispersion of nanotubes.

Study the modifications induced by alpha particles in cellulose nitrate NTD
Vacuum, 2019Cellulose Nitrate (CN-85) polymer samples were irradiated by alpha particles with different fluences varying from 1.45 × 106 to 7.2 × 106 particles/cm2 using a 241Am source. The optical and structural alterations produced in CN-85 nuclear track detector (

The synergistic effect of benzhydrylation and iodination of the flammability of alpha‐cellulose
Journal of Applied Polymer Science, 1971AbstractCellulose samples modified by iodination, benzhydrylation, and benzhydrylation followed by iodination were pyrolyzed to investigate the potential flame retardance of such treatments. Their effect on crystallinity, rate of thermal degradation, char production, and pyrolysis products was determined.

Mechanical Properties of Poly(Butylene Succinate) Reinforced with Alpha Cellulose
Advanced Materials Research, 2015The objective of this study is to prepare α-cellulose reinforced poly (butylene succinate) composites (PBS/α-cellulose). The effect of amount α-cellulose on the mechanical properties of the composites was investigated. To improve interfacial interaction between PBS and α-cellulose, glycidyl methacrylate grafted poly (butylene succinate) (PBS-g-GMA) was

Ignition of alpha-cellulose and cotton fabric by flame radiation
Fire Technology, 1969Spectral emission characteristics of radiation affect the ignition behavior of flammable materials subjected to the same incident irradiance levels from different irradiating sources. Experimental flame radiation results were obtained in an ignition cabinet utilizing sheets of flames as the irradiating source.

Digestion of Alpha-Cellulose by Larvæ of Anobium punctatum De Geer
Nature, 1951PARKIN1 demonstrated that the larval gut of the common house borer Anobium punctatum De Geer contained an enzyme or enzymes which produced reducing sugars from isolated oak α-cellulose in vitro. Falck2 and Muller3 concluded from chemical analyses of sound and digested wood that some α-cellulose was digested by the larvae.

Effects of Alpha-Cellulose Supply on the Working Life of MCF Slurry in MCF Polishing
JSME 2020 Conference on Leading Edge Manufacturing/Materials and Processing, 2020Abstract High precision surfaces exhibit prominent capabilities for enhancing the imaging quality, expanding the visibility of equipment, simplifying structures, and reducing total costs of optical systems. Hence, they are regarded as essential optical surfaces for replacing traditional elements to modify optical systems, including space

Viscous and damping properties of magnetic compound fluids containing alpha-cellulose
International Journal of Applied Electromagnetics and Mechanics, 2014Viscous, magnetization and damping properties of magnetic compound fluids containing fibrous material such as alpha-cellulose were investigated experimentally. It is shown that adding fibrous material to magnetic functional fluids is effective on increasing viscosity on the fluid while the amplification ratio of damping force in the presence of ...
