This chapter explains the evolution of academic tetrafluoroethylene (TFE) barricades for the purpose of preparing fluoropolymers, which to the best of knowledge began a little over 25 years ago with a facility at Clemson University's Hunter Laboratories. It explains initial barricade was primarily for TFE cylinder sto…

The ability to evaluate mucoadhesion properties depends to a great extent on the model surface used in a specific research. The state of the mucus model surface and its content are crucial parameters affecting the results of the bioadhesion assay. This chapter describes a variety of experimental methods that have been…
Treating ocular disorders presents many problems for drug delivery. The preferred means for ocular drug delivery is via the topical route, due to ease of access and patient compliance. Ocular mucosa plays an important role in drug delivery and is the focus of this chapter. The chapter lists some of the main individual…
Complexity of mucin molecules permits multiple interaction mechanisms ranging from covalent chemical bonds to physicochemical and colloidal interactions. In real settings, the majority of mucoadhesive materials and delivery systems act concomitantly through multiple mechanisms, resulting in complex compounding interac…
This chapter presents a survey of the open literature to examine the various methods of polytetrafluoroethylene (PTFE) pyrolysis so as to build a coherent image of the art, and to present and evaluate the known catalytic reactions of the pyrolysis products, with emphasis on those of tetrafluoroethylene (TFE). The lite…
New classes of amorphous perfluorinated polymers with extraordinary properties were developed and commercialized by DuPont (as Teflon® AF), Asahi Glass (as Cytop®), and Solvay (as Hyflon® AD). Teflon® AF and Hyflon® AD are a family of copolymers of 2,2-bis(trifluoromethyl)-4,5-difluoro-1,3- dioxole (I) and 2,2-bis(tri…

The ligands of platinum anticancer complexes determine a multitude of factors including reactivity, distribution, tumour selectivity and penetration, cellular accumulation, mode of cytotoxicity, type of pharmaceutical formulation required, and route of drug administration. They can be tailored to fine-tune physicochem…
Renewable feedstocks are gaining traction in supplementing and replacing traditional petrochemical products. Seed oils are attractive renewable feedstocks because they are available on a large scale at low prices and contain multiple functional groups for further modifications. To help understand the effect of ethylen…

Mucoadhesion is said to occur when two surfaces, one of which is a mucous membrane, adhere to each other. Mucoadhesive materials are typically hydrophilic macromolecules containing numerous hydrogen bond forming groups, the carbomers, cellulose derivatives and chitosans being well-known examples. Mucoadhesion is said…
Photocatalytically active nanostructures require a large specific surface area with the presence of many catalytically active sites for the oxidation and reduction half reactions, and fast electron (hole) diffusion and charge separation. Nanowires present suitable architectures to meet these requirements. Axially segm…
Little is known of the effects of combined blast and thermal loading on structures within an explosive fireball. This paper documents and discusses the response of 2mm thick steel plate within a fireball of a 41kg TNT equivalent explosive. This continues the study of work investigating the synergistic response of stru…
Spectroscopically resolved emission from single nanocrystals at cryogenic temperatures provides unique insight into photophysical processes that occur within these materials. At low temperatures the emission spectra collapse to narrow lines revealing a rich spectroscopic landscape and unexpected properties, completely…
Field theoretic approaches have been particularly useful in studying colloidal and biological systems, in which long-range electrostatic interactions are important. For weakly coupled systems, the field theoretic methods reduce to the commonly known Poisson- Boltzmann (PB) theory [Chapman (1913); Gouy (1910)], which ha…
We present an iterative design method for the coupling and the mode conversion of arbitrary modes to focused surface plasmons using a large array of aperiodically randomly located slits in a thin metal lm. As the distance between the slits is small and the number of slits is large, significant mutual coupling occurs b…
Abstract Two coordination polymers, namely {[Mn(2,4′‐bpdc)(bimb)(H2O)0.5]·0.5H2O}n (1) and [Mn(4,4′‐bpdc)(bimb)]n·2.5H2O (2) [2,4′‐bpdc = biphenyl‐2,4′‐dicarboxylate, 4,4′‐bpdc = biphenyl‐4,4′‐dicarboxylate, and bimb = 1,4‐bis(1‐imidazol‐yl)‐2,5‐dimethyl benzene], were hydrothermally synthesized by reactions of mangan…
Leakage radiation spectroscopy of organic para-Hexaphenylene (p-6P) molecules has been performed in the spectral range 420-675 nm which overlaps with the p-6P photoluminescence band. The p-6P was deposited on 40 nm silver (Ag) films on BK7 glass, covered with SiO2 layers. The SiO2 layer thickness was varied in the ran…
ABSTRACT In this article, boric acid‐modified poly(aryl ether sulfone) (PES‐B) membranes were prepared by solution blending, solution casting, evaporation, and programmed temperature curing method for the first time. The chemical modification of poly(aryl ether sulfone) was accomplished by the curing of poly(aryl ethe…
