We describe here a drug depot hydrogel system comprising sildenafil (Viagra®) incorporated in mesoporous silica nanoparticles (60 nm) and conjugated with a thermosensitive poloxamer, which presents a high efficiency against prostate cancer.
A highly stable face-extended cluster-organic framework incorporating infinite inorganic guests is hydrothermally constructed, in which the tetrahedral O-centred Cu4O cluster is firstly found as the face-extended structure building unit to further provide a diamondoid cluster-organic framework with high thermal and st…
Asymmetry in the electronic structure of low-dimensional carbon nanomaterials is important for designing molecular devices for functions such as directional transport and magnetic switching. In this paper, we use density functional theory to achieve an asymmetric spin distribution in a typical (9,0) carbon nanotube (C…
A “two-step growth” method for obtaining large dimensional bridge-like Bi 2 Se 3 nanostructures was proposed for the first time.
Hydrophilic periodic polymer possessing [AB x AC] n repeating sequence was synthesized by aqueous radical addition-coupling polymerization using water-soluble inclusion complex of nitrosobenzene and Me 2 -β-cyclodextrin.
This work reports a simple process for preparation of stable and uniform magnetite nanoparticles (Fe3O4) at low temperature. The method is supported in three single steps and provides low-sized functionalized magnetite nanoparticles at lower temperatures than the obtained by similar methods. The samples have been char…
The structure of photocatalytic and photoluminescent binary vanadate of the general formula “CaZnV 2 O 7 ” has been investigated using X-ray powder diffraction.
Conventionally, commercialized spherical silicone powders, such as silicone resin powder [INCI: POLYMETHYLSILSESQUIOXANE (PMSQ beads)] and silicone rubber powder [INCI: DIMETHICONE/VINYL DIMETHICONE CROSSPOLYMER (DVDC beads)], have been formulated into cosmetics for soft and smooth feeling. Due to the low crosslink de…
New hybrid organic-inorganic composites based on sulfur-containing styrene copolymers and allyl glycidyl ether and tetraethoxysilane were obtained by a sol-gel synthesis method. The membranes created on the basis of composites have proton-conductive properties and are characterized by a higher heat-exchange capacity c…
Tungsten oxide nanowires (NWs) were successfully deposited on the membrane of micro hotplates (ams, Germany) by a very simple and scalable thermal oxidation technique. Synthetized nanostructures were morphologically investigated by mean of a FE-SEM (LEO 1525) and the structure was analysed by X-Ray Diffraction and Ram…
The paper presents a systematic investigation of the effects of a corrosive condition on grain boundary corrosion and other deleterious phenomena in a nickel alloys commonly used in nuclear waste containers, chemical refining plants and steam generator tubes. Grain boundary corrosion is investigated with the aid of mi…
Heavy-fermion superconductors (HFSCs) are regarded as outside the purview of BCS theory because it is usually constrained by the inequality , where EF, μ, kB, and θD are, respectively, the Fermi energy, chemical potential, Boltzmann constant, and the Debye temperature. We show that this restriction can be removed by i…
Real attribute of femininity, wearing high-heeled shoes is a dress conduct of women in daily and professional tasks. Objectives. Consider the kinematics changes induced by walking heels and determine a height of comfort in the least intrusive possible locomotor pattern. Materials and methods. Fifteen young women had n…
Spontaneous encapsulation of drugs into carbon nanotubes (CNTs) has attracted great interest because of their importance in biological and biomedical devices. In this work, the diameter dependence of 20 drugs on the carbon nanotube size was explored via molecular dynamics (MD) simulation. Negative free energy of inter…
In this study doped SnO2 thin films have been prepared by spray pyrolysis technique using an alcoholic precursor solution consisting of stannic chloride (SnCl4.5H2O), ammonium fluoride (NH4F) and palladium chloride (PdCl2). Optimization on the deposition parameters was done so as to obtain high quality thin films. The…
Hydrophilized graphite felt has been used, for the first time , for the electrochemical detection of Hg 2+ ions both as single metal species and via its simultaneous detection with Pb 2+ . To do so, square wave voltammetry (SWV) method was developed with alginate modified graphite felt as working electrode. The struct…
This study was conducted to assess hydrolytic influence of cellulase (C) on the physicochemical stability of chitosan (CH)/hydroxypropyl methylcellulose (HPMC) films in time of storage (T). Initially, nine films were physically characterized by contact angle, water vapour permeability (WVP), water activity (aw) , tens…
Phase change materials (PCMs) have been applying in many areas. One of them is energy field. PCMs are interesting for the energy sector because their use enables thermal stabilization and storage of large amount of heat. It is major issue for safety of electronic devices, thermal control of buildings and vehicles, sol…
We sprayed a mixture of steam and water on an aluminum deposited glass surface and observed the removal process. In addition, we observed ethanol droplet deformation after impact on solid surface in ethanol vapor atmosphere. As a film removal mechanism, we propose following scenario; initially high-speed droplets crea…
Regenerative medicine consisting of cells and materials offers a new approach for repairing and regenerating the organs and tissues. More and more researches focused on the magnetic nanobiomaterials due to its superior advantages to traditional materials. However, the toxicity of nanosized magnetic particles cannot be…
