In this work, new type of methacrylate monomers, with fluorine and ketone chain (4-florophenyl)-2- oxo ethyl methactylate (FFMA) were synthesized. The free-radical-initiated copolymerization FFMA with acrylonitrile (AN) were carried out in 1,4-dioxane solution at 65 o C using 2,2’-azobisisobutyronitrile (AIBN) as an i…

Composite in composite material means, two or more materials combined on a macroscopic scale to form a useful material. The advantage of composite is, they exhibit the best qualities of their constituents and also some qualities that neither constituent possesses. These properties make advanced composites extremely at…

The Aim of this paper is to evaluate the effect of transportation node protection on the resilience of pipeline systems to the development of damage by the mechanism of progressive blocking of nodes as well as the efficiency analysis of the employed protection measures. Damage to a point element of a system due to sim…
Quasi-2D perovskites strike a good balance between high performance and stability for solar cell applications. Formamidinium iodide doping could improve thermal stability and broaden optical absorption, yet tends to cause poor morphology. The work featured on this cover presents a new strategy to optimize the morpholo…
Spinel-type NiFe2O4 with oxygen vacancies was prepared via a simple hydrothermal method followed by mild reduction under hydrogen flow and used as a catalyst for the oxygen evolution reaction (OER). The oxygen-deficient spinel-type oxide nanoparticles exhibited excellent electrocatalytic activity and long-term durabil…
The cover feature shows an acid-base bifunctional faujasite (FAU; zeolite Y) that has a hierarchical structure and is formed by the solid-state dealumination of NaX nanosheets with ammonium hexafluorosilicate. The obtained material acts as a catalyst in the tandem deacetalization-Henry reaction of benzaldehyde dimethy…
The Antimony thiorea thin films which are the subject of this study were prepared by ultrasonic spray pyrolysis technique. The Antimony thiorea thin films were investigated depending on the substrate temperature. The optical and structural characteristics of these films were determined using UV–vis spectrophotometry a…
Relevant: Is the study of the response of biological macromolecules to external stimuli. Often the reaction of macromolecules has an effect of structural self-regulation. In this case, their reaction is not only external infl uence, but also the spatial-temporal motions of the macromolecule. In this situation deserves…
The environmental impact of aviation is multifaceted. Aircraft engines emit noise, heat, particulates and gases that contribute to climate change and, in general, to pollution. Aviation is shown to be the fastest growing mode of transportation in terms of passenger numbers. Passenger traffic, expressed in revenue pass…
A high-purity uranium/plutonium mixed oxide material from the Material Identification and Surveillance (MIS) Program inventory has been studied with regard to gas generation and corrosion in a storage environment. Sample 5501579 represents process plutonium oxides from high purity mixed oxides and mixed oxides from al…
Cliff failure is occurring and threatens to expose pits and shafts. Steep slope angles = FoS < 1 = high probability of failure and retreat. EQ magnitude > 5.5 could initiate failure where FoS > 1. Fracture characterization (location, orientation, etc.) is essential for predictive analysis of at-risk cliff failure loca…
Absorption ( K ), reflection ( R ) and wavelength modulated transmission ( ΔT/Δλ ) spectra in SnS, SnS 2 and SnSe crystals were investigated in temperature range from 300 to 10 K. Excitonic states were discovered in all investigated compounds. Parameters of observed excitons and character of electron transitions parti…
In this paper we investigate the prospective of use of some nanostructured organic crystals as efficient thermoelectric material for infrared biosensors. Nowadays, the infrared sensors are widely implemented in thermal imaging system, night vision systems and different personal or clinical devices for health monitorin…
In fabricating CdS/CdTe photovoltaic devices by close space sublimation method, thermal annealed in CdCI 2 ambient at 400 °C at the interface is deposited an i -CdO layer by magnetron sputtering. Comparative analysis of electrical, photovoltaic parameters and photo-response spectral distribution is studied. The insert…
