Present work aimed at investigating the friction and wear of martensitic stainless steel of grade 410. This steel is used in nuclear industry for various moving components due to its high strength and moderate corrosion resistance. Properties of this material depend upon the heat treatment to which subjected to. The w…
Atmospheric pressure plasma systems are routinely used to treat the surfaces of thermally sensitive materials. There are wide ranges of commercial plasma jet systems available, and for the end user, it can be difficult to directly compare the power outputs of these sources. This paper evaluates the use of a thermal im…
We report a didactic and simple example of the subtleness in the balance of intermolecular and molecule–substrate interactions and its effect on molecular self-assembly. The study is performed on two closely related molecular blends of copper phthalocyanines and pentacene, in each of which one of the two molecules is…
The possibility of promoting the self-cleaning properties of the cement materials was verified by implementing the obtained nitrogen and carbon co-modified titania-based (TiO 2 /N,C) photocatalysts into the cement plates. Additionally, unmodified TiO 2 (Grupa Azoty Zakłady Chemiczne POLICE S.A., Poland) and a commerci…
Aluminum boron carbide metal matrix composites (Al-MMC) have got wide applications in aeronautical and automobile industries due to their excellent mechanical and physical properties. Due to the presence of harder reinforcement particles, machining of these composites is a difficult task. The results of experimental i…
Direct conversion of methane, the dominating component of natural and shale gases, into key chemical feedstock and liquid fuels has long been a big challenge in chemistry and chemical engineering [1, 2]. The industrial processes for methane-resourced higher hydrocarbons (e.g. olefin and gasoline) are based on indirect…
I-shaped stiffened skin was manufactured by a new co-cured resin film infusion process (co-RFI) with fiber preform stiffener and prepreg skin. One kind of epoxy resin film and four kinds of carbon fiber prepreg were used. Resin flow behavior, processing quality, and mechanical performance were investigated for co-RFI…
Abstract Antarctic seaweeds play an important ecological role, but the vast macroalgal beds, typical of the shallow-water zone, are not efficiently grazed. However, macroalgal thalli are covered by epiphytic diatoms which represent a rich food source for higher trophic levels. We describe the abundances, growth form s…
This study developed a novel one-step method for the synthesis of well-dispersed CZTSe nanoparticles from Cu, Zn, Sn, Se elemental powders using a solvent-thermal reflux technique. Polyetheramine was used as a solvent and chelating agent, which provided two NH2 bonding sites at the ends as well as long, continuous epo…
Abstract [Mn(LH)(H2O)]n {1, where LH2– is the dianion of N‐(4‐carboxybenzyl)iminodiacetic acid} has been synthesized and its crystal structure has been determined. The crystal of 1 is built from 1D polymeric ladder‐shaped chains that extend to a 3D supramolecular architecture through H‐bonds. The compound was characte…
Experimental observations of the optical and electromagnetic fields generated by lightning flashes during the last 50 years have significantly advanced our knowledge concerning the mechanism of the lightning flash. Nevertheless, this knowledge is not as exhaustive as that of long laboratory sparks due to our inability…
Abstract The conductivity of a single aromatic ring, perpendicular to its plane, is determined using a new strategy under ambient conditions and at room temperature by a combination of molecular assembly, scanning tunneling microscopy (STM) imaging, and STM break junction (STM‐BJ) techniques. The construction of such…
This study is focused on the synthesis and characterization of hydroxy-apo-10'-carotenal/quantum dot (QD) conjugates aiming at the in vivo visualization of β-ionone, a carotenoid-derived volatile compound known for its important contribution to the flavor and aroma of many fruits, vegetables, and plants. The synthesis…
Friction stir processing (FSP) is as a novel modifying technique to synthesize surface composites. An attempt has been made to synthesis AA6082/TiC surface composite using FSP and to analyze the effect of tool rotational speed on microstructure and microhardness of the same. The tool rotational speed was varied from 8…
Static and dynamic autocorrelations of charge density, composed of positive point ions and instantaneous distribution of electron density, are studied in liquid Li in a pressure range from ambient to 186 GPa using ab initio molecular dynamics simulations. It is shown analytically that the long-wavelength limit of the…
The effects of Sn and Zn seed layers on the rectifying characteristics of Pd/ZnO thin-film Schottky diodes fabricated on n-Si substrates by the thermal evaporation method have been investigated in this letter. The field emission scanning electron microscopy images show the changes in the surface morphology of the ZnO…
Nanodimensional monodispersed Cu–MnO heterostructures were synthesized via a facile solution-based method. Cu–MnO heterostructures with narrow size distribution were successfully achieved in the presence of organic surfactants to prevent agglomeration during the growth process. Furthermore, the unique architecture of…
A dry de-NO x technique based on a highly efficient photochemical oxidation process was demonstrated for a simulated flue gas of a diesel engine using a lab-scale reaction chamber. A hybrid system of an ultraviolet (UV 185, 254 nm ) lamp and aerosolized H 2 O/hydrogen peroxide (H 2 O 2 ) was employed. De-NO x characte…

Crystals of molecular complexes of trimethyltrioxane (TMT) with chloroform (CF), bromoform (BF), dichloromethane (DCM), and dibromomethane (DBM) as well as those of pure TMT were grown in situ and characterized by single crystal X-ray crystallography. The CF and BF complexes, as well as those of DCM and DBM, are isost…
