Graphene/carbon aerogels (RF) were prepared via a Sol-Gel process in graphene oxide (GO) solution using resorcinol (R) and formaldehyde (F) as carbon precursor. The structure, morphology and pore-size distribution of the samples were characterized by XRD, Raman spectrum, SEM and N2 adsorption desorption method. The re…
Обнаружено, что продуктами реакций пивалата, бензоата и цимантренкарбоксилата марганца(II) с 3,5-диметилпиразолом (Hdmpz) являются моноядерные комплексы (Hdmpz)4Mn(OOCR) (R = But, Ph) и биядерный комплекс , содержащий сольватную молекулу пиразола. Полученные комплексы выделены с высоким выходом в монокристаллическом в…
Fosinopril, the unique phosphinic acid deriva- tive among the angiotensin-converting enzyme inhibitors, is a poorly water-soluble and highly lipophilic substance, exhibiting poor bioavailability following oral administra- tion. The inclusion complex between the drug substance and hydroxypropyl-b-cyclodextrin (HPBCD) w…
Artemisinin (ART) is an oral antimalarial agent with poor aqueous solubility and low oral bioavailability. The present study describes the preparation of artemisinin with polyethylene glycol (PEGs 1500, 4000 and 6000) as a solid dispersion to increase the solubility of artemisinin. Solid dispersion of the drug were pr…
Abstract NiTi shape memory alloys have gained increased interest in various industries, including biomedical and aerospace applications due to their unique properties such as shape memory effect and superelasticity. Martensitic phase transformation in NiTi significantly affects the surface integrity characteristics. T…
In this paper, we reported the compositional, morphological and structural properties of the alumina(Al2O3) thin films prepared by sol-gel technique and annealed between 800 °C to 1200 °C for 1-hour in an air atmosphere. The deposited films were polycrystalline in nature. Thin films were found uniform and adherent to…
This paper shows successful hindering of the negative effects of the cobalt binder in the process of coating WC-Co cutting tools with CVD diamond films. The strategy was creating a boron-rich layer on the surface of the WC-Co substrates as an interlayer to block Co migration. The traditional boriding technique was imp…
The development of green synthesis route method for the synthesis of nanoparticles or nanophosphor using echo friendly chemicals and plant product have received attention in the recent times as it is environment friendly and economical method. Gd2O3: Er 3+ , Yb 3+ Nanophosphor have been prepared using glucose both as…
We prove that any 12-neighbour packing of unit balls in is composed of parallel layers of the same hexagonal structure as the layers in the densest lattice packing.
The dynamic properties of a magnet with magneticion spin of 3/2 and an isotropic spin interac� tion of a general form have been investigated. Only four phase states can be realized in the system under con� sideration at various relationships between the material parameters: the ferroand antiferromagnetic phases with s…
Zinc sulphidenanocrystalline thin film has been grown on glass plate through successive ionic layer adsorption and Reduction by SILAR technique at ambient conditions, which involves multiple dipping of a substrate in the cationic and anionic precursors. The nanocrystalline thin film has beencharacterised by X-Ray diff…
A new phenomenon was observed for p-men- thane-1,2,4-triol, i.e., the substance with the same molecular structure occurs in two forms with different polarity. The form with a lower polarity is eluted with ethyl acetate in column chromatography; the form with a higher polarity is eluted with methanol. The crystals isol…
The article considers the task of competitiveness prolongation for the aircraft put into operation. It describes the means to increase aerodynamic efficiency of commercial aircraft and provides the outcome of regional aircraft modification.
In this paper we introduce and investigate an interesting subclassMK (k) (;h ) of functions which are analytic in the punctured unit disk and meromorphically close-to-convex. By using the principle of subordination, we establish several properties such as inclusion rela- tionship and distortion theorems for functions…
This Paper proposes the high-power non-linear loads and high-power adjustable-speed motor drives, such as mainly used in electric novel ships, the shunt active power filter is proposed here to reduce the harmonic contents in source voltage and source currents of harmonic polluted three phase system supplying a Non- li…
The present study examined effect of salt (NaCl) on enzymatic and non-enzymatic antioxidant activity in vegetatively propagated plantlets of Excoecaria agallocha, a mangrove species, during hardening. The propagated plantlets were exposed to 0, 50, 100, 150 and 200 mM NaCl for 28 days, where the enzymatic and non-enzy…
The paper presents the objective function of metal spraying process and optimizing its ultrasonic field. For CCR objective function, named quality function of resulted couple, were taken into account the following factors: resistance to adhesion surface; porosity; tensile strength; wear resistance; hardness of the mat…
The prediction of strength in silica needs knowledge of failure behaviour of defects in the surface region. Pores and cracks are studied by using the Finite Element method. The results for pores are given in terms of stresses, the results for cracks by stress intensity factors.

This paper compares numerical and analytic solutions for a typical plasmonic waveguide consisting of a thin film sandwiched between a cladding cover and a substrate. Two configurations are analyzed using the Electromagnetic Waves, Frequency Domain interface (emw) of the RF Module of COMSOL Multiphysics: dielectric-met…
