Organonitrogen compounds present in fuel oils are deleterious to the environment as well as refining catalysts. Herein, functional polybenzimidazole (PBI) nanofibres fabricated in the presence of N-compounds (nitrogen-containing compounds) were employed for the selective adsorption of quinoline, pyrimidine and carbazo…
MACE (Metal-Assisted Chemical Etching) approach has drawn a lot of attentions due to its ability to create highly light-absorptive silicon surface. This method can generate numerous cylindrical shape microstructure on the surface of silicon like a forest, which is called “silicon nanowires arrays”. This structure can…
The paper presents results of experimental research of selected solid rocket propellants with the use of modern thermal analysis techniques. Differential Scanning Calorimetry (DSC) was used to determine specific heat values in the temperature range from –100 °C to 100 °C with the heating rate of 10 K/min. Simultaneous…
The acceptor strength of the 1,2-diphenyl-3,5-pyrazolidinedione residue is re-evaluated based on the spectral-fluorescent properties of donor–acceptor dyes. Low fluorescence of the title compounds is explained by the low-lying forbidden ππ*-state.
The present work evaluated the effect on charge transfer in functionalized TiO 2 nanostructured systems using different binders. We highlight the conditions required to form self-assembled systems by varying the number of layers, as well as by substituting them for an organic binder, cysteine. Additionally, we study t…

In this paper, results of the simulation tools URANUS and PICLas are compared to Plasma wind tunnel experiments. This is done for validation purposes of catalytic modelling within these tools. Therefore, the used experimental setup, from which the discussed simulation case is derived, and challenges in the flow charac…
Nitrogen strengthened austenitic stainless steels is gaining its popularity in replacing the SS 304 component by cheaper AISI 201 grade in many industrial application including repair and maintenance due to its outstanding combination of mechanical property and corrosion resistance. Gas metal arc welding (GMAW) is pre…
This article describes highly luminescent ionic compounds in liquid and crystalline states, where a naphthalene moiety is conjugated to an imidazolium center decorated with two different lengths of alkyl chains.
Picosecond laser device is used to treat Aluminum samples, the appearance of the treated samples is affected by the variation of laser focus distance and the samples surface roughness. Samples with smoother surface before laser treatments show dark colors and high increase in surface roughness after laser treatments,…
The present investigation aims at developing copper chilled aluminum alloy (LM-13) reinforced with beryl using stir casting method. Matrix alloy was melted in a composite making furnace to a temperature of about 700°C to which preheated reinforcement particles was added (3 wt.% to 12 wt.% in steps of 3 wt.%), stirred…
A dimensional conversion process of semiconducting lead bromide perovskites is followed by electrospray ionization mass spectrometry (ESI-MS), powder X-ray diffraction (PXRD), microcalorimetry and crystallography.
The possibility of retaining Cs+ and Co2+ bound by immobilization processes in the cement matrix is defined as the subject of its investigation: the cement matrix formulation, the water/cement ratio, the amount of waste, and the porosity of such a structure. Implementing the standard leaching method by Hespe the possi…
Due to the increase in population and demand for consumer products, chemical industries responsible for their production have grown rapidly year by year. Even if the positive effects are evident, they still threaten the environment due to their high energy consumption and harmful emissions. There is an urgent need to…
The mechanical characteristics of siltstone under high static load and frequent dynamic disturbance were investigated by the improved split Hopkinson pressure bar (SHPB), which is used to simulate the failure phenomenon of the extracted ore drift owing to high stress concentration and blasting disturbance in Dongguash…
As data center ethernet switches scale towards 100Tbps, fiber links that keep pace with interconnecting exploding DCI capacity will face significant cost, power and engineering barriers. In this talk, we describe FRESCO, an approach to bring highly coherent WDM Terabit links inside the data center without the need for…
Traditional medicinal chemistry has directed hits and leads toward larger size and more lipophilic compounds during optimization. Avoiding molecular obesity has been a major challenge in drug discovery. Nowadays, useful metrics are developing to substantially help medicinal chemists to find more efficient ligands of o…
Nanoparticles composed by the biodegradable polymers possess several advantages, i.e. improved stability of therapeutic agents against degradation, controlled drug release, and efficient targeting. The current investigation describes the detail of the formation and size control of biodegradable Polycaprolactone (PCL)…
The machinability of brittle materials is strongly dependent on machining conditions. In the present work, we perform ultra-precision single point diamond turning experiments of monocrystalline Si(100) using diamond cutting tools. The machined surface quality is characterized by evaluating surface topography and surfa…
We have investigated the structural, transport properties and electronic structure of CaIrO3 (CIO) thin film on (LaAlO3)0.3(Sr2AlTaO6)0.7 (100) substrate. X-ray diffraction results reveal the phase purity and the epitaxial growth of the film with partial tensile strain. The overall behavior of the temperature dependen…
