Dependence of Sheet Resistivity on Urbach Energy of Nano TiO2 - Graphene-based Electrode for DSSC Application [PDF]

open access: yes
The importance of renewable energy cannot be over-emphasized. Titanium IV oxide (TiO2 ) is the most suitable semiconductor for dye-sensitized solar cells (DSSC) due to its chemical stability, non-toxicity and excellent optoelectronic properties.

Reference Question Data Mining [PDF]

open access: yes, 2010
This exploratory study investigated the feasibility of using reference questions as an important tool in the construction of study guides, instructional outreach, and collection development at a small, four-year university in Lake Charles, Louisiana. The

Measurement of the W boson helicity fractions in the decays of top quark pairs to lepton+jets final states produced in pp collisions at s=8TeV

open access: yesPhysics Letters B, 2016
The W boson helicity fractions from top quark decays in tt‾ events are measured using data from proton–proton collisions at a centre-of-mass energy of 8TeV.

Pseudorapidity dependence of the anisotropic flow of charged particles in Pb–Pb collisions at sNN=2.76 TeV

open access: yesPhysics Letters B, 2016
We present measurements of the elliptic (v2), triangular (v3) and quadrangular (v4) anisotropic azimuthal flow over a wide range of pseudorapidities (−3 ...

A new route to graphene layers by selective laser ablation

open access: yesAIP Advances, 2011
Selectively creating regions of spatially varying thickness may enable the utilization of the electronic properties of N-layer (N=1 or more) graphene and other similar layered materials (e.g., topological insulators or layered superconductors) for novel ...

Non-abelian (hyperscaling violating) Lifshitz black holes in general dimensions

open access: yesPhysics Letters B, 2015
We consider Einstein gravities coupled to a cosmological constant and multiple SU(2) Yang–Mills fields in general dimensions and find that the theories admit colored Lifshitz solutions with dynamic exponents z>1.

Sizeable magnetic circular dichroism of artificially precipitated Co clusters in amorphous carbon

open access: yesAIP Advances, 2012
This study examines sizeable magnetic circular dichroism (MCD) in Co(20%)-doped amorphous carbon (a-C) films. While as-grown films exhibit a non-detectable MCD signal, films that undergo rapid thermal annealing (RTA) at 600°C in a vacuum yield broad MCD ...

Interpreting the 750 GeV diphoton excess in minimal extensions of Two-Higgs-Doublet models

open access: yesPhysics Letters B, 2016
It is shown that the 750 GeV diphoton excess can be explained in extensions of Two-Higgs-Doublet Models that do not involve large multiplicities of new electromagnetically charged states.

Mid-infrared Fe2+:ZnSe semiconductor saturable absorber mirror for passively Q-switched Er3+-doped ZBLAN fiber laser

open access: yesAIP Advances, 2018
A mid-infrared (mid-IR) semiconductor saturable absorber mirror (SESAM) based on Fe2+:ZnSe for passively Q-switched Er3+-doped ZBLAN fiber laser has been demonstrated. Fe2+:ZnSe SESAM was fabricated by electron beam evaporation method.

On anisotropic black branes with Lifshitz scaling

open access: yesPhysics Letters B, 2016
In this paper, based on the method of scalar perturbations, we construct the anisotropic charged Lifshitz background perturbatively up to leading order in the anisotropy.
