Hydrophilic patterning of octadecyltrichlorosilane (OTS)-coated paper via atmospheric-pressure dielectric-barrier-discharge jet (DBDjet)
This study demonstrates a method for patterning paper-based microfluidic devices. An octadecyltrichlorosilane (OTS) solution is used to coat a chromatography paper to make it hydrophobic. A low-temperature (~ ...

Ar dielectric barrier discharge jet (DBDjet) plasma treatment of reduced graphene oxide (rGO)–polyaniline (PANI)–chitosan (CS) nanocomposite on carbon cloth for supercapacitor application
A low-temperature (< 42 °C) Ar dielectric barrier discharge jet (DBDjet) is used to treat screen-printed reduced graphene oxide (rGO)–polyaniline (PANI)–chitosan (CS) nanocomposites used as the electrodes of g...

Investigation of ultrashort (< 1 min) calcination processes for conversion of Pt–SnOx from mixture of chloroplatinic acid and tin(II) chloride
We investigate the ultrashort (< 1 min) calcination process for Pt–SnOx catalysts converted from a mixture solution of chloroplatinic acid and tin(II) chloride in air. An electric furnace is used to test the ultr...

Nitrogen Atmospheric-Pressure-Plasma-Jet Induced Oxidation of SnOx Thin Films
SnOx thin films that were rf-sputter-deposited under various gas flow ratios ([O2]/([O2] + [Ar]) OFR = 3.0, 3.6, 4.2 and 4.8 %) were rapidly annealed using atmospheric pressure plasma jets (APPJs) in temperature ...

HfZnO/ZnO Heterostructures Fabricated Using Low-Cost Large-Area Compatible Sputtering Processes
We investigated the electrical properties of the rf-sputtered HfxZn1-xO/ZnO heterostructures. The thermal annealing on ZnO prior to the HfxZn1-xO deposition greatly influences the properties of the heterostructur...

New Optimal Asymmetric Quantum Codes Derived from Negacyclic Codes
The construction of quantum maximum-distance-separable (MDS) codes have been studied by many researchers for many years. Here, by using negacyclic codes, we construct two families of asymmetric quantum codes. ...

Characterization of rf-sputtered HfMgZnO thin films
MgZnO becomes amorphous or short-range-ordered with the addition of hafnium oxide. The films are rf-sputter deposited onto glass substrates (Eagle 2000, Corning Inc.) from Mg0.05HfxZn0.95-xO targets (x=0, 0.025, ...
