Abstract In the “Hypothesis” paper entitled “Lanthanides‐Based Catalysis in Eukaryotes” (IUBMB Life 2018 Nov;70(11):1067–1075), we analyzed the possibility that Ce3+‐dependent methanol dehydrogenases (MDHs) could be found not only in archaea and bacteria but also in eukaryotic organisms. This hypothesis was based on t…
Multistep 18 O isotope exchange procedures and subsequent analytical techniques can be used to elucidate the effect of ambient gas atmospheres on the transport properties of oxide ion-conducting materials utilized in high-temperature solid oxide devices for electrochemical energy conversion. In this contribution, we p…
The paper has analyzed influence of additives representing a group of thermoplastic elastomers and complex thermoplast-based modifiers on fatigue life of asphalt concrete. Regularities in time have been determined in the paper and close values of their physical and mechanical properties have been obtained while using…
This study focused on fabrication of polyurethane (PU) foams and its composites based on hydroxylated bioepoxy (B) and petroleum based synthetic epoxy (E), crosslinker and wood fillers. The fabrication of foams: B and E with different wood filler size such as flake (L) and powder (P) on different composition ratios of…
Drug delivery that enables spatial and temporal control is essential to optimal pharmacotherapy, among which photothermal heating has been widely used as a light-responsive drug release. However, the heating mechanism underlying the application has been rarely elaborated. Herein, we used a template-assisted approach t…
The paper presents solutions of two contact problems for the annular plate die on an elastic half-space under the action of axisymmetrically applied force and moment. Such problems usually arise in the calculation of rigid foundations with the sole of the annular shape in chimneys, cooling towers, water towers and oth…
Effect of diagonal path on the physical properties of compact and conventional ring yarns has been investigated. The compact and conventional ring yarns have been spun using three completely different paths in the ring frame, like normal path, right diagonal path and left diagonal path. The yarn spun by the left diago…
Copper pipelines are widely used while designing modern heating systems, water and gas supply of residential buildings and these pipelines have a number of advantages in comparison with steel and plastic pipelines. The main reason for limited use of copper pipes is their cost which is practically twice as much as cost…
The luminescent properties of Ce 3+ , Eu 2+ , Ce 3+ -Tb 3+ , and Eu 3+ in the mullite (Al 6 Si 2 O 13 ) host were investigated for realization of full colors phosphors with a single type host. Ce 3+ and Eu 2+ in mullite showed blue photoluminescence (PL), whereas green and red emission were obtained in the Ce 3+ -Tb 3…
The effects of cellulose nanowhiskers (CNWs) and irradiation dose on phase separation behavior as well as rheological and physical properties of Poly vinyl methyl ether (PVME) nanogels are investigated. Interactions between CNWs and polymer chains lead to the dehydration of PVME chains. Increasing the irradiation dose…
In this study, poly(azomethine)s with cresol and pyrrole as side chain units were synthesized in three steps. In the first step; symmetrical dialdehyde bromide (DAB), in the second step; symmetrical derivatives (DAB-1 and DAB-2) of DAB using p -cresol and pyrrole, respectively, and in the third step; poly(azomethinecr…
Owing to weak interfacial bonding and incompatibility between graphene and polymer, there are several challenges in the fabrication of graphene-based polymer composites with an effective gas barrier. Hence, it is necessary to enhance the affinity between polymers and graphene. We selected graphene oxide (GO) as filler…
As density is one of the basic physical properties of materials, an accurate density standard is absolutely essential. To determine density with high accuracy and precision, two 1‐kg single‐crystal silicon spheres (NMIJ‐S4 and NMIJ‐S5) are used as the primary standard at the National Metrology Institute of Japan. For…
The effect of bromine (Br2) doping on the hole transfer properties in amorphous polyethylene (PE) oligomer is studied by utilizing a multi-scale computational approach without adopting any empirical models. The computational method comprises molecular dynamics simulations, quantum chemical calculations, and kinetic Mo…
Nanocomposites of polycarbonate (PC) and polyethylene oxide (PEO) embedded with graphene oxide (GO) nanopowder have been prepared using casting method. Prepared nanocomposites are studied and investigated using different characterization techniques. The X-ray diffraction (XRD) pattern reveals the semi-crystalline natu…
As an efficient energy-saving piece of equipment, an air-source heat pump can not only reduce the energy consumption required for heating, but can also reduce the pollution from fossil consumption. However, when an air-source heat pump operates under low temperatures and high humidity, the heat exchanger surface of it…
In this work, by the example of the system of linear low‐density polyethylene—multi‐walled carbon nanotubes (LLDPE/CNTs), specific features of the nanocomposite structure modified by severe plastic deformation (SPD) are studied. The effect of SPD on the mechanical properties and electrical conductivity is analyzed. It…
Abstract Graphene was grown on both r-plane and c-plane sapphires by low-pressure chemical vapor deposition without using a metal catalyst. The growth pressure was systematically changed to investigate how the growth pressure effects the graphene growth. Consequently, it was found that the coverage of the graphene inc…

Based on previous scientific research, it has been found that they possess have very interesting properties such fire resistance, m…
Surface properties are an essential feature in a wide range of functional materials. In this article, we summarize strategies developed in our group that employ nanoparticles and proteins as nanobricks to create thin-film coatings on surfaces. These coatings contain tailorable surface functionality based on the proper…
