Clinoptilolite supported rutile TiO2 composites: Synthesis, characterization, and photocatalytic activity on the degradation of terephthalic acid
Clinoptilolite supported rutile TiO2 composites were synthesized for the enhancement of its photocatalytic performance in the degradation of the aqueous terephthalic acid solution under UVC illumination by the increase in ...
Theory of optical properties of graphene quantum dots
We present here a theory of the optical properties of graphene quantum dots (GQDs) with tunable band gaps by lateral size confinement, from UV to THz. Starting from the Hartree-Fock ground state, we construct the correlated ...
Evidence for exclusive γγ → W+ W− production and constraints on anomalous quartic gauge couplings in pp collisions at √s = 7 and 8 TeV
A search for exclusive or quasi-exclusive γγ → W+W− production, via pp → p(*)W+W−p(*) → p(*)μ±e∓p(*) at √s = 8 TeV, is reported using data corresponding to an integrated luminosity of 19.7 fb−1. Events are selected by ...
Low-power and low-cost stiffness-variable oesophageal tissue phantom
Biological tissues are complex structures with changing mechanical properties depending on physiological or pathological factors. Thus they are extendible under normal conditions or stiff if they are subject to an inflammatory ...
Experimental modeling of silicate-based geothermal deposits
Scaling by metal silicates represents a major obstacle for geothermal systems. A composition that enables the fabrication of artificial deposits is necessary for the rapid testing of potential inhibitors. In this work, ...
Search for neutral color-octet weak-triplet scalar particles in proton-proton collisions at √s= 8TeV
A search for pair production of neutral color-octet weak-triplet scalar particles (Θ0) is performed in processes where one Θ0 decays to a pair of b quark jets and the other to a Z boson plus a jet, with the Z boson decaying ...
Pseudorapidity distribution of charged hadrons in proton-proton collisions at s=13 TeV
The pseudorapidity distribution of charged hadrons in pp collisions at s=13 TeV is measured using a data sample obtained with the CMS detector, operated at zero magnetic field, at the CERN LHC. The yield of primary charged ...
Cosmological consequences of a variable cosmological constant model
(World Scientific Publishing, 2017-06)
We derive a model of dark energy which evolves with time via the scale factor. The equation-of-state is studied as a function of a parameter α introduced in this model as = (1 - 2α)/(1 + 2α). In addition to the recent ...
Development of mentor teacher role inventory
(Taylor and Francis, 2011-05)
This study aimed to develop and investigate the validity and reliability of the Mentor Teacher Role Inventory (MTRI). A total of 1843 student teachers in the Distance English Teacher Training Program participated in the ...
