The introduction of the 157-nm wavelength for next-generation optical lithography has created a need for new soft (polymeric) or hard (quartz) pellicle materials optimized for that wavelength. The design and development of ultratransparent fluoropolymers suitable for 157-nm soft-pellicle applications has produced several promising candidate materials with absorbances <0.03/μm to achieve pellicl...

The wide-spreading use of innovative lightweight materials like advanced composites and metal coated plastics in several fields of applications has pushed toward an increasing interest in the characterization of the shielding performances of test materials. In the paper, we revisit the conventional methods of measuring shielding effectiveness of materials, and introduce the nested reverberation...

Energy dispersive X-ray spectroscopy microanalysis (EDX), scanning electron microscopy (SEM), and Archimedes' Principle were used to determine the characteristics of inorganic filler particles in five dental alginates, including Cavex ColorChange (C), Hydrogum 5 (H5), Hydrogum (H), Orthoprint (O), and Jeltrate Plus (JP). The different alginate powders (0.5 mg) were fixed on plastic stubs (n = 5...

The results of coating capacitive micromachined ultrasonic transducer (CMUT) arrays with two different biocompatible materials, parylene-c and polydimethylsiloxane (PDMS), are reported. These materials were characterized for use with CMUTs to enable direct contact transcutaneous and in vivo imaging. A passivation coating is required to provide electrical isolation to the active areas of the dev...

We have theoretically investigated the effect of a coating made of the elastically dissimilar material on the acoustic phonon properties of semiconductor nanowires. It is shown that the acoustic impedance mismatch at the interface between the nanowire and the barrier coating affects dramatically the phonon spectra and group velocities in the nanowires. Coatings made of materials with a small so...

In the solar energy industry great emphasis has been placed on the development of better and efficient systems as these are utilized in the form of heat and electricity for both domestic and industry purpose. The system is integration of several sub systems namely coated solar collectors; absorbers; plates shape and size, type of coatings, and techniques of applying these coatings are major gov...

Objective(s): Drug delivery via mucosal routes has been confirmed to be effective in inducing strong immune responses. Liposomes could enhance immune responses and mucoadhesive potentials, make them useful mucosal drug delivery systems. Coating of liposomes by mucoadhesive polymers succeeded in enhancing immune responses. Our studies aim at preparation and characterization of trimethylchitosan-...

It is well known that the mechanical properties of fiberglass reinforced "phenolic moulding compounds" are significantly enhanced if the glass particles are coated with silane coupling agents before compounding. It has been shown that improvements obtained by using scanning electron microscopy techniques are due to better bonding of phenolic resin to the surface of treated glass fibers. These o...

Cellulose nanofibers or ‘‘whiskers’’ derived from tunicates were coated with PEDOT:PSS to produce high-aspect-ratio nanorods with high electrical conductivity. Films made from these PEDOT:PSS whiskers have surface resistivities as low as 97 U/,. The nanorods were found to disperse well in polar organic solvents such as dimethylformamide, which allowed the fabrication of nanocomposites with iner...

A volume-surface integral equation (VSIE) formulation is developed for determining the electromagnetic TM scattering by a two-dimensional conducting cylinder coated with an inhomogeneous dielectric/magnetic material. The electric field integral equations (EFIEs) are utilized to derive the VSIE. The surface EFIE is applied to the conducting surface, while the volume EFIE is applied to the coatin...
