Natural rubber bound phenolic antioxidant, 2,6-di-tert-butyl-4-vinylphenol (2,6-DBVP), was prepared from natural rubber and 2,6-DBVP in both solution and melt state. The 2,6-DBVP had been synthesized from 3,5-di-tert-butyl-4-hydroxybenzaldehyde and methyltriphenylphosphonium iodide ( $MePPh_3I$ ) by Wittig reaction (…
Lactic acid is used in various industrial areas such as the food, pharmaceutical, textile and other chemicalindustries. In this study, 49 lactic acid bacteria were isolated from oral microbiota of voluntary patients.These isolates were screened for their lactic acid production abilities. The isolate which has a highpo…
Fluorescence anisotropy decay is a popular optical technique to study the structure, size, shape, and even functions of biomolecules. The method measures the time dependence of the depolarization of a fluorophore and is therefore sensitive to the changes in the rotational motion (e.g., aggregation and binding) or chan…
Cancer is a group of diseases in which normal cells are converted to cells capable of autonomous growthand invasion. In the chemotherapeutic control of cancer, drugs are usually given systemically so they reachtoxic levels in cancer cells. This causes serious side effects in healthy cells. Another important problem wi…
Highly crosslinked copolymers of 1‐vinyl‐2‐pyrrolidone (VP) were obtained in the form of microspheres by combined suspension–emulsion polymerization. The porous structure of the copolymers was created by the use of proper diluents. The main parameters of porous structure were established in the dry and wet states. Thr…
Here, we report computational studies of the SH3 protein domain interacting with various single-walled carbon nanotubes (SWCNT) either bare or functionalized by mimicking the proline-rich motif (PRM) ligand (PPPVPPRR) and compare it to the SH3-PRM complex binding. With prolines or a single arginine attached, the SWCNT…
We investigated condensate mobility and resulting heat transfer performance on Cu based water repellent surfaces including hydrophobic, superhydrophobic and oil-infused surfaces. We observed the transient microscale condensation behaviours up to 3 hours with controlling the supersaturation level at 1.64. We experiment…
Polypyrrole (PPy) films were successfully prepared on the self-assembled silane monolayers (SAMs) for electromagnetic interference (EMI) shielding. X-ray photoelectron spectroscopy was used to estimate the surface properties of SAMs and hydrolytic silane. The deposition process of PPy films on silane SAMs surface was…
This paper reports modified graphene-based materials as metal-free electrocatalysts for oxygen reduction reaction (ORR) with outstanding electrocatalytic activity in alkaline conditions. Nitrogen-doped graphene samples are synthesized by a novel procedure. The defect density in the structure of the prepared materials…
Abstract Review: overview of smart chemistry developed and utilized in the last 5—10 years in polymer‐based drug delivery nanomedicine; 506 refs.
Abstract The surface activities of two amphiphilic diblock copolymers containing 2‐ethyl hexyl methacrylate‐b‐N,N′‐dimethylacrylamide (EHMA‐b‐DMA) possessing hydrophobic segments of different chain lengths were studied. Toward this end, surface pressure−area (π−A) isotherms, static and dynamic elasticities and the ν e…
This paper reports a novel nanocomposite anode for lithium-ion battery, with high initial specific capacity (1200mAh/g) and good capacity retention (850mAh/g remaining after 30 cycles). Sufficient silicon nanoparticles (SiNPs) at anode make a significant contribution to specific capacity increase. Moreover, nano void…
Choke valves used in oil and gas production can be exposed to serious corrosive conditions during oil well stimulation when concentrated acids are used. These valves are also exposed to extreme erosive conditions. Hardmetals with varying binder content (5–7 wt%), binder composition (cobalt and a mixture of cobalt, nic…

Abstract Two new molecule‐based magnetic materials were prepared, namely, [CuCyclam(CH3CN)2][Ni(bdt)2]2 and [CuCyclam][Ni(bdt)2]2 (bdt = 1,2‐benzenedithiolate). The former compound is characterized by a two‐dimensional layer structure, in which axially coordinated acetonitrile molecules prevent cation–anion stacking.…
A weighted dual mean square criterion for stochastic equivalent linearization method is considered in which the forward and backward replacements are weighted. The normalized weighting coefficient is suggested as a piecewise linear function of the squared correlation coefficient and is defined by the least square meth…
This study highlights the growth mechanisms involved in the atmospheric pressure plasma polymerisation of a phosphorus-containing monomer.
The final goal of this study is to develop all-Ge-based energy harvesting modules consisting of mechanical generators, rectifiers, capacitors and power managing digital circuits. To make basis for the development of modules, we focused on development of the Ge electrodes for electric double layer capacitors (EDLC). Fi…
We estimate the optical constants of a biological thin layer (Allium cepa) by surface plasmon resonance (SPR) spectroscopy. For this study, the fresh inner thin epidermis of an onion bulb was used and stacked directly on gold (Au) and silver (Ag) film surfaces in order to identify the shift in SPR mode of each metal f…
