Unprotected colloidal nanoparticle suspensions are promising building blocks for various types of catalysts. The work featured on the Back Cover shows that exposing a Pt precursor reaction mixture at room temperature to light leads to the formation of well-defined, unprotected Pt nanoparticles, whereas no particles ar…
Mechanical rebar couplers are preferable in the advanced building construction and structural design of antiseismic elements. The paper presents destructive inspection techniques used to investigate stress fields (tensile and compressive) and deformation curves for mechanical rebar splicing. The properties of mechanic…
The currently applied criteria of identification of imperfections based on results of Radiographic Testing have no unambiguous description in regulatory documents. Therefore, there is a lack of coherence between opinions of the experts who are interpreting images on radiographic films .Authors suggest dividing images…

We propose a model for predicting the fluctuations of electron states in thin films as function of film thickness. The model was derived based on the assumption of the existence of potential barrier fluctuations on the film surface. Since the wave functions of electrons in the film is determined by the boundary condit…
El animo de este trabajo de investigacion ha sido sumarse a las opiniones mas optimistas en el campo de la nanotecnologia y tratar de hacer un aporte en el desarrollo de una mas de las piezas de su engranaje; la elaboracion de materiales nanoestructurados con propiedades a medida. Para ello, se ha analizado la influen…
We report the lattice dynamics of transition metal thin films by using the ultrafast electron diffraction. We observe a suppression of the diffraction intensity in a few picosecond after the photoexcitation, which is directly interpreted as the lattice heating via the electron-phonon interaction. The electron-phonon c…
A progressive collapse mitigation strategy is to ensure load redistribution when a column fails due to fire. The study seeks to understand whether welded unreinforced flange-bolted web (WUF-B) moment connections can effectively redistribute loads in a structural system subjected to fire when a critical column is lost.…
FeCo/Cu core shell structure with FeCo as a core and copper as the shell has been successfully synthesized by displacement reaction. The morphology, grain size, lattice strain, and magnetic properties of all the samples were examined by using transmission electron microscopy (TEM), X-ray diffraction (XRD), and vibrati…
It is the main idea and work of this paper that mathematical methods are used to predict the lowest energy structure of clusters with powerful computing capability of the computer. A modified dynamic lattice searching method is proposed in this paper for Au clusters. It is applied to the Au clusters with Gupta potenti…
Plasma annealing, which attributes structure change below melting as a lattice weakening effect solely by the high density of excited carriers, has been widely accepted for non-thermal phase transition. By carrying out time-dependent density functional theory-molecular dynamics for Ge2Sb2Te5 alloy, we show that such a…
The welds are the site of high residual stresses, localized in the vicinity of the weld cracks.Their presence caused many type of damage modes as stress corrosion, fatigue, sudden failure and increasing the temperature of ductile-brittle transition.Residual stresses in restrained welds and weld repairs are very comple…
Purpose – The purpose of this paper is to present thermal properties of palladium-carbon films prepared by physical vapour deposition (PVD)/chemical vapour deposition (CVD) methods. Design/methodology/approach – Thin palladium-carbon films were prepared at Tele- and Radioresearch Institute. Test structures containing…
Here we present a detailed study of the THz and FIR response of the mixed perovskite manganite system Eu$_{1-x}$Ho$_x$MnO$_3$ for holmium concentrations x = 0.1 and 0.3. We compare the magnetic excitations of the four different magnetically ordered phases (A-type antiferromagnetic, sinusoidally modulated collinear, he…
Electronic structures of 3d transition element Cu-doped anatase TiO2 and (Cu+N) co-doped anatase TiO2 are studied by using the first-principle method based on density functional theory. The calculations are performed by using the projector augmented wave method within the generalized gradient approximation as implemen…
