One-dimensional (1D) nanomaterials such as nanowires, nanotubes, nanorods, nanofibers and nanobelts have drawn a lot of attention arising out oftheir unique optical, magnetic, electrical, and otheremerging properties. Among them nanofibers provide several amazing characteristics such as very large surface area to volu…
This project work presents a single phase shunt active power filter based on synchronous detection method. Due to wide use of nonlinear single phase power electronic devices in low voltage side has increased harmonic pollution in the power system to the larger extent. Improving power quality has become the biggest cha…
Abstract : The focus of this project was to develop synthetic methodologies and evaluate Titanium Nitride (TiN)-based nanomaterials, as prospective contrast agents for Photoacoustic (PA) Tomography, according to the following program: 1. Development of methodologies for preparation of stable nano-suspensions of TiN na…
Correction: nanoindentation experiments for single-layer rectangular graphene films: a molecular dynamics study
Bioplastics can be defined as plastics made of biomass such as corn, sugarcane etc. These substances have been increasingly spotlighted as means to saving fossil fuels, reducing CO2 emission and plastic wastes. Biodegradability of Bioplastics has been widely publicized in society and the demand for packaging is rapidl…
We have studied the phonon specific heat in single-layer, bilayer and twisted bilayer graphene. The calculations were performed using the Born-von Karman model of lattice dynamics for intralayer atomic interactions and spherically symmetric interatomic potential for interlayer interactions. We found that at temperatur…
Distortion-induced fatigue cracking has occurred in many types of steel bridge structures, especially welded structures where high local stresses exist. This research experimentally investigates the fatigue cracking behaviors around the web gap of welded I-beam. A total of nine specimens in three series of experiments…
Problemy przy spawaniu łukiem krytym paneli ścian szczelnych z nowej bainitycznej stali 7CrMoVTiB10-10 przyczyniły się do poszukiwania innych technologii wy- twarzania paneli z tej stali. Jedną z nowo opracowa- nych technologii jest spawanie hybrydowe laser+MAG. W pracy przedstawiono wyniki prób spawania paneli ścian…
Ciągły rozwój robotyzacji procesów produkcyjnych dyktuje niższe ceny rynkowe konstrukcji i wyrobów spawanych. Wdrożenie robotów spawalniczych w danym przedsiębiorstwie wiąże się z szeregiem zmian organizacyjnych także w strukturze zatrudnienia. Przedstawiono wpływ robotyzacji na zatrudnienie, kwalifikacje personelu or…
The structures and stabilities of the Fe N (CO)m (N = 1-4, m = 1-5) clusters have been theoretically studied at the density functional theory (DFT) and ab initio levels of theory. In particular, the energetic, structural and vibrational frequencies of carbon monoxide (CO) chemisorptions on iron clusters are studied an…
MOTIVATION: Protein domains are fundamental units of protein structure, function and evolution; thus, it is critical to gain a deep understanding of protein domain organization. Previous works have attempted to identify key residues involved in organization of domain architecture. Because one of the most important cha…

W pracy przedstawiono wyniki oceny mikrostruktury wybranych stopów niklu, tzn. 600, 617 i 625. Stosując mikroskopię świetlną poddano ocenie obserwowane mikrostruktury w odniesieniu do ich składu chemicznego. Przedstawiono również typowe mechanizmy utwardzaia występujące w stopach niklu.Abstract The paper presents the…
This article is the third part of the work devoted to plasma chemical processing of plastic waste (and other toxic organic compounds) into hydrogen and other liquid products. The obtained results are crucial to solving global environmental and energy challenges of our time. The article presents a brief overview of the…
Background and Objective: Poly D,L-lactic-co-glycolic acid (PLGA) is known as biodegradable and biocompatible polymer. These polymers have recently received much attention in tissue engineering. The aim of this study was to investigate the biological behavior of the bone marrow stromal cells (BMSCs) in culturing with…
The purpose of this paper is to investigate the performance of supplemental cooling and heating system equipped with the 1 kW thermoelectric module. The system consist of 96 thermoelectric modules, heat sink with louver fin and water cooling jacket which is attached on the hot side of the thermoelectric module. The co…

This paper summarizes the ballistic considerations of a general project concerning the protection against the threats associated with improvised explosive devices (IEDs). IEDs generate two kinds of threats: blast and fragments. One possible protection combines a ballistic textile (Kevlar®) to stop the fragments and a…
