We demonstrate that the halide perovskite planar solar cells with the architecture of ITO/PEDOT:PSS/Perovskite/PCBM/LiF/Al show a switchable dual operation of descent photovoltaic and quite bright electroluminescence in visible range. In our experiments, the active layer is made of a mixed halide perovskite (MAPbBr 2…
Nanofibrous scaffolds are often used to reconstruct damaged tissues/organs. Unfortunately the lack of producing three-dimensional (3D) nanofiber results in their restricted applications. Therefore, bulky-shaped gelatin nanofibers were fabricated through novel rapid freeze casting (RFC) technique to simulate extracellu…
Nowadays, due to the decline in oil supplies on the one hand and raising the price of petroleum, on the other hand, countries have led to other sources of fuel and energy. The use of methods such as the production of light hydrocarbons from synthesis gas is highly regarded by the Fischer-Tropsch process, in these coun…
The requirements for controlling Particulate Matter (PM) and gaseous emissions emitted from gasoline direct injection (GDI) engines, especially under cold start conditions, and the introduction of bio-alcohols fuels in the market demands the development of novel efficient aftertreatment technologies. Understanding the…
The work in this thesis aims to investigate the ductility of s-HD (solid hydrogenation disproportionation) processed book mould cast NdFeB material in order to develop a novel processing route for producing fully dense magnetic material with a high energy product. A major drawback of NdFeB–based alloys is that they ar…
The present study aims at investigating nonlinear free vibration of thermally buckled functionally graded nanobeam. The nonlocal nonlinear Euler-Bernoulli beam theory as well as linear eigenmodes of a functionally graded nanobeam vibrating around the first buckling configuration are employed to derive a system of ordi…
BACKGROUND: Intrinsic structural disorder is a common property of many proteins, especially in eukaryotic and virus proteomes. The tendency of some proteins or protein regions to exist in a disordered state usually precludes their structural characterisation and renders them especially difficult for experimental handl…
Abstract The aim of this work is the development of a thermodynamically consistent fully coupled thermo‐viscoplastic material model for metals. The model is based on a split of the free energy into a thermo‐elastic, a thermo‐plastic and a purely thermal part and covers nonlinear cold‐work hardening and thermal softeni…
Derivation and application of
Understanding the interactions between proteins and biomaterials underpins the development of novel biomaterials that could produce a specific response towards the surrounding tissue, depending on the application. In this thesis, a combination of molecular dynamics (MD) simulations and experimental techniques was depl…
A new type of unsaturated poly ester-amide was prepared by melt polycondensation and characterized completely. Influence of heat treatment conditions and cross-linking content on mechanical and degradation properties of unsaturated polyester-amide were studied. Results suggested that the newly synthesized unsaturated…
The defect in work rolls directly influence the forming cost and the final shape of the product. The researchers tend to investigate the thermo-mechanical stress in work roll of rolling machines. These stresses may reduce the roll life. Since the investigation of the thermo-mechanical stress in work roll with real-con…
Pattern formation occurring in a two-dimensional system of rod-like particles has been simulated using a lattice approach. The rod-like particles were modelled as linear k -mers of two mutually perpendicular orientations ( k x - and k y -mers) on a square lattice with periodic boundary conditions (torus). Two differen…
The present research was conducted to investigate the effect of water stress and silver nanoparticles on morphological traits of some saffron ecotypes. The experiment was done in form of split plot factorial in a randomized complete block design format in three replications at research farm of Birjand University with…

Efficient and selective oxidation of alcohols with NaIO4 catalyzed by an organic-inorganic hybrid material in which manganese(III)5,10,15,20-tetrakis(4-aminophenyl)porphyrin chloride, MnIII(TAPP)Cl, is covalently linked to a Lindqvist structure of polyoxometalate, Mo6O192-, at room temperature is reported. The effect…
Schiff base complexes of transition metals are of particular interest to inorganic chemists because of their structural, spectral and chemical properties, which are often strongly dependant on the nature of the ligand structure. Large number of metal (II) complexes with Schiff-base ligands has been extensively studied…
This work is an experimental justification of the choice of the temperature and time modes designed for the heat treatment of real magnetrons, the end result of which is the initial decomposition of barium carbonate into barium oxide. We experimentally determine the temperatures of polymorphic transitions in barium ca…
In this paper we introduce a novel methodology to transmit the origin to the center of a polygon in a molecule structure such that the special axis be perpendicular to the plane containing the polygon. The mathematical calculation are described completely and the algorithm will be showed as a computer program.
Let $G$ be a group, we say that $G$ satisfies the property $mathcal{T}(infty)$ provided that, every infinite set of elements of $G$ contains elements $xneq y, z$ such that $[x, y, z]=1=[y, z, x]=[z, x, y]$. We denote by $mathcal{C}$ the class of all polycyclic groups, $mathcal{S}$ the class of al…
