(2009-05-15)Ammonia refrigeration systems are widely used in industry. Demand of these systems is expected to increase due to the advantages of ammonia as refrigerant and because ammonia is considered a green refrigerant. Therefore, ...
-
(2012-11-01)Aflatoxin is a potent biological toxin produced by fungi Aspergillus flavus and A. parasiticus. Current quantification methods for aflatoxins are mostly established on immunoaffinity columns which are both costly and labor ...
-
(2010-01-14)A variety of functional thin films can be produced using the layer-by-layer assembly technique. In this work, assemblies of anionic clay and cationic polymer were studied with regard to film growth and gas barrier properties. ...
-
(Texas A&M University, 2007-09-17)Layer-by-layer (LbL) assembly was used to produce highly conductive thin films with carbon black (CB) and polyelectrolytes. The effects of sonication and pHadjustment of the deposition mixtures on the conductivity and ...
-
(2020-07-28)Exhaled breath analysis is a non-intrusive, point-of-care monitoring technique capable of detection and diagnosis of respiratory diseases, offering rapid response and recovery rates. Detection of volatile organic compounds ...
-
(2022-06-03)MXenes are a class of two-dimensional nanomaterials which have drawn interest in a wide variety of fields (e.g., energy storage, sensing, catalysis, separation, etc.). While there are hundreds of possible MXene compositions, ...
-
(2012-07-16)Thin layers with high barrier to oxygen and other gases are a key component to many packaging applications, such as flexible electronics, food, and pharmaceuticals. Vapor deposited thin films provide significant gas barrier, ...
-
(2009-05-15)Conductive thin films of poly(3,4-ethylenedioxythiophene)-polystyrenesulfonate (PEDOT-PSS) were created via layer-by-layer assembly. The PEDOT-PSS was used in an aqueous solution as an anionic polyelectrolyte, with both ...
-
(2018-05-04)This thesis presents three investigations into the responsive physical and thermal properties of polyelectrolyte layer-by-layer assemblies. The first study focuses on hydrogen bonded, layer-by-layer assembled films and ...
