The Universal Selection Source: Plastics & Elastomers
A SpecialChem Client requires a technology to optimize the performance of UV filters from its formulation. Technologies that could enhance usual UV filters are also of interest.
A SpecialChem Client is seeking a transparent technology to protect organic particles from high alkaline environment and UV radiation.
This technology allows selective separation of metals from solid or liquid mixtures. Given the nature of this technology, it can be tailored to separate specific elements. Industri...

Thermal management has always been a major concern in the design of high frequency, high power electronic devices. For example, historically, in many power amplifier designs, the vast majority of the power that needs to be dissipated is from the high power field effect transistors, or FET's, themselves. In these cases, the high power dissipation ...

Thermoelectricity is the direct conversion of
temperature gradient to electric voltage, and vice-versa.
There are several potential applications of
thermoelectricity, ranging from clean noiseless cooling, to
waste-power harvesting in automotives. The performance
of thermoelectric devices is still a challenge, and many
approaches have been res...

Energy Density and Corona Resistance (or Voltage Endurance) are two critical properties that are commonly used to characterize the performance of materials targeted for insulation and capacitor applications. A common problem in such dielectric designs involves the maximization of both energy density and voltage endurance. One of the strategies that...

Block copolymers, block copolymer and inorganic nanoparticle composite materials and devices including such composite materials. The block copolymers have polar functional groups that can facilitate the dispersion of inorganic nanoparticles in composite materials. The nanoparticles are especially useful in optical/microelectronic sensors, transisto...

From the elastomeric materials, side significant changes occurred in these past years, with many more options offered to product designers and engineers. Vulcanized rubbers were the first to be developed, and therefore have a long history in multiple uses. Flexible PVC entered the game, and thanks to their cost competitive pricing and almost infini...

Disperse Multiwall carbon nanotubes (MWCNTs) are incorporated aqueous N-hydroxy methyl acrylamide, which is subjected to crosslinking to develop a transparent conductive composite free standing film. The effects of the concentration of MWCNTs and temperature on optical and electrical properties of nano-composites are investigated. Interestingly, on...

In this work, maleic anhydride grafted styrene–ethylene–butadiene–styrene copolymer (SEBS-g-MA) and carbon nanotubes (CNTs) were introduced into the immiscible polypropylene/polystyrene (PP/PS) blend. Among the three polymer components, SEBS-g-MA has the strongest affinity to CNTs; thus, it exhibits dual effects to adjust the phase morphology of th...

A common problem that arises when viewing an object through an intervening transparent medium is glare. Glare may be defined as the substantially specular reflection of ambient light on the viewer side of the transparent medium from one or more surfaces of the transparent medium. Thus, glare light travels an optical path that extends from the sourc...
