Synthesis and characterization of poly(methylphenylsilylene) poly(methyl methacrylate) block copolymers [PDF]

open access: yes, 1998
Block copolymers of poly(methylphenylsilylene) and poly(methyl methacrylate) have been synthesized by condensation of alpha,omega-dichloropoly(methylphenylsilylene) with poly(methyl methacrylate)-lithium. The alpha,omega-dichloropoly(methylphenylsilylene)

Dielectric relaxations of poly(2-norbornyl methacrylate) and poly(3-methyl-2-norbornyl methacrylate) [PDF]

open access: yes, 2001
Dielectric behaviour of poly(2-norbornyl methacrylate) (P2NBM) and poly(3-methyl-2-norbornyl methacrylate) (P3M2NBM) was studied. The effect of the methyl substituent on the norbornyl ring is to decrease the temperature of the dynamic glass transition ...

Chemically Fueled Systems Chemistry Across Length Scales

open access: yesAdvanced Functional Materials, EarlyView.
Chemically fueled reaction cycles regulate processes through single and multiple catalytic sites on the molecular and assembly scale. This gives rise to unique kinetically controlled properties/functions like spatio‐temporal catalysis, oscillations, optical properties, and perform work.

Thermal expansion of irradiated poly(methyl methacrylate) [PDF]

open access: yes, 1987
The thermal expansion coefficient of irradiated poly(methyl methacrylate) is measured in the temperature range 80-350K using a three-terminal capacitance technique. The samples are irradiated with gamma-rays from a 60Co source in air at room temperature.

The comparison of nanoparticle adjuvant with the montanide adjuvant for hyper-immunization to produce anti-snakebite serum [PDF]

open access: yesJournal of Advanced Biomedical Sciences, 2018
Background & Objective: Currently selection and use of nanoparticle adjuvant is very important. Due to the lack of effective anti-snakebite serums to treat it and high cost of purchasing external anti-snakebite serums, preparation of suitable internal ...
