Abstract: An antimicrobial air treatment device and a method of its construction. The antimicrobial air treatment device comprises an antimicrobial metal nanoparticle mesh comprising a steel support mesh and a layer of copper nanoparticles disposed on the steel support mesh. The antimicrobial air treatment device may be in the form of a facemask or a component of a moving air filtration system such as an HVAC system, an automobile cabin air filtration system, and an air purifier. The antimicrobial air treatment device may contain one or more filtration layers of filtration medium. The method of constructing the antimicrobial air treatment device involves the preparation of the antimicrobial metal nanoparticle mesh by an electrodeposition technique.

Abstract: A thermoelectric module comprising nanostructured SnO and SnO2, and electrodes arranged between two electrical insulating substrates is described. The nanostructured SnO may be in the form of nanosheets and acting as p-type pillars of the module. The nanostructured SnO2 may be in the form of nanospheres and acting as n-type pillars of the module. This thermoelectric module is evaluated on the voltage, current, and power of the electricity generated once subjected to a temperature gradient.

Abstract: An organic light emitting diode (OLED) utilizes dysprosium incorporated tris-(8-hydroxyquinoline) aluminum (Alq3-Dy) as the emissive layer. The OLED, which can be fabricated as a multi-layer device with each layer having a thickness of 30-300 nm, provides a luminance value at a voltage ranging from 24V to 30V of 3000-15000 cd/m2. In comparison to similar OLEDs which utilize pure Alq3, the diodes with the Alq3-Dy layer provide an electroluminescence intensity 20 times higher than diodes with a pure Alq3 layer (Alq3 OLED). In addition, the peak position (EL emission band) of the Alq3-Dy OLED is shifted to the higher wavelength side by 10 nm compared to that of the pure Alq3 OLED (from 515 nm to 525 nm).

Abstract: Coaxial electrospinning is used to encapsulate a chitin-lignin based hybrid gel with polycaprolactone (PCL). Antibiotics and/or other bioactive agents loaded into the core and/or shell layer of the fibrous platform are released in a controlled and sustained manner that effectively inhibits both Gram-positive and Gram-negative bacteria without cytotoxicity to mammalian cells. The PCL shell layer provides longer life for the CL gels in a wet environment and allows sustainable drug release. The PCL-coated CL nanofiber scaffolds can be loaded with antimicrobial nanoparticles, antibiotics, oxygen-releasing agents, antioxidants and/or growth factors that promote healing when used as a controlled drug release dressing for chronic wounds, such as diabetic ulcers.

Abstract: A method for making an epoxy-carbon nanotube polymer composite. Carbon nanotubes of fly ash are initially dispersed in an organic solvent, then an epoxy resin is added to the dispersion. The epoxy-carbon nanotube mixture is ultrasonicated, degassed, mixed with a curative, then placed into a mold to cure to form the composite. The composite produced contains different amounts of fly ash carbon nanotubes homogeneously dispersed an epoxy resin matrix, and exhibits unusual physical properties such as viscoelasticity and flexibility.
