A Sb2(S1-x/Sex)3 graded-composition is obtained by a sequential deposition of Sb2S3 and Sb2Se3 onto a mesoporous TiO2 photoelectrode followed by thermal annealing at 300 °C. The compositional graded-solar cells exhibit a greatly enhanced performance compared to pristine Sb2S3-sensitized or Sb2Se3-sensitized solar cell…
Polysulfobetaines, polymers carrying highly polar zwitterionic side chains, present a promising research field by virtue of their antifouling properties, hemocompatibility, and stimulus-responsive behavior. However, limited synthetic approaches exist to produce sulfobetaine copolymers comprising hydrophobic components…
An integrated and reproducible chemical process was developed to fabricate the N-doped mesoporous carbon by using melamine resin as nitrogen source. A two-dimensional carbon framework of graphene sheets was also used as a conductive substrate in order to boost the performance of such nitrogen-doped carbon materials. C…
We report a giant electric-field control of magnetization (M) as well as magnetic anisotropy in a Co40Fe40B20(CoFeB)/Pb(Mg1/3Nb2/3)0.7Ti0.3O3(PMN-PT) structure at room temperature, in which a maximum relative magnetization change (ΔM/M) up to 83% with a 90° rotation of the easy axis under electric fields were observed…
Nickel and cobalt (Ni-Co) binary oxide nanosheets with mesoporous structure are prepared by a facile approach based on the formation and disassociation of nickel/cobalt-citrate complex, and they show an ultra-high Faradaic capacitance up to 1846 F g(-1) and excellent rate capability. On this basic, advanced aqueous as…
Light-responsive polymeric micelles have emerged as site-specific and time-controlled systems for advanced drug delivery. Spiropyran (SP), a well-known photochromic molecule, was used to initiate the ring-opening multibranching polymerization of glycidol to afford a series of hyperbranched polyglycerols (SP-hb-PG). Th…
Nanoparticles are rapidly being developed and trialed to overcome several limitations of traditional drug delivery systems and are coming up as a distinct therapeutics for cancer treatment. Conventional chemotherapeutics possess some serious side effects including damage of the immune system and other organs with rapi…
The development of new and improved photothermal contrast agents for the successful treatment of cancer (or other diseases) via plasmonic photothermal therapy (PPTT) is a crucial part of the application of nanotechnology in medicine. Gold nanorods (AuNRs) have been found to be the most effective photothermal contrast…
Lanthanide-doped upconversion nanoparticles (UCNPs) have shown great promise in bioapplications. Exploring new host materials to realize efficient upconversion luminescence (UCL) output is a goal of general concern. Herein, we develop a unique strategy for the synthesis of novel LiLuF4 :Ln(3+) core/shell UCNPs with ty…
An effort was made to formulate drug free transdermal patches by using different polymers like ethyl cellulose, poly vinyl pyrrolidone and eudragit. Four groups of twelve formulations of drug free transdermal patches were prepared by solvent evaporation technique in which each group have different plasticizer concen…
A thermal diode that rectifies heat current is one of the basic devices for functional heat control. Frequency response is an important feature of many electric devices, such as diodes and transistors. Frequency response measures the ability of a device to process high-frequency signals. In this paper, we systematical…
Using the experimental research of the dependence of the degree of curing resin PHAM from content in the composite material wood chips room-dry humidity and increase the degree of curing due adsorption capacity of dry wood, resulting from a polymer solution FEMME free water is removed, can inhibit the reaction of poly…
Dendrimers are a new class of synthetic polymers which have a tree or star shape like structure, with a central core, interior branches and terminal groups which embellish the surface. It can be synthesized by a repetitive step-growth polymerization process. They are highly branched and monodisperse macromolecules. Th…
The static and dynamic properties of striped colloidal particles are obtained using molecular dynamics computer simulations. Striped particles with n = 2 to n = 7 stripes of alternating electric charge are modeled at a high level of detail through a pointwise (PW) representation of the particle surface. We also consid…
Plasmon enhancement of photoinduced charge injection from a perylene dye into a large TiO 2 cluster is studied theoretically. A system is investigated where a spherical metal nanoparticle (MNP) is placed near the dye at the cluster surface. The simulations account for optical excitation of the dye coupled to the MNP a…
Recently, hybrid materials using poly ethylene glycol and porous nanocrystals have been developed for drug release. In this study, a series of poly ethylene glycol (PEG)/NaY zeolite and PEG/MCM-41 nanocomposites get synthesized. These materials are characterized using FT-IR spectroscopy, XRD, TGA and SEM. After loadin…
We present here an analytical method, based on the kinetic theory, to determine the impact of defects such as cavities on the thermal conductivity of a solid. This approach, which explicitly takes into account the effects of internal pore surfaces, will be referred to as the Phonon Interface THermal cONductivity (PITH…
Motivated by the experimental realization of D022-type Mn3Ge (001) films [Kurt et al. Appl. Phys. Lett. 101, 132410 (2012)] and the structural stability of D03-type Heusler alloy Mn3Ge [Zhang et al. J. Phys.: Condens. Matter 25, 206006 (2013)], we use the first-principles calculations based on the full potential linea…
Abstract Quinine sulfate dihydrate (QNS), IUPAC name: (8S,9R)-6-methoxy-4-quinolenyl-5-vinyl-2-quinuclidinyl methanol sulfate dihydrate, was tested as corrosion inhibitor for carbon steel in 1.5 mol L−1 HCl solution using the potentiodynamic polarization and the electrochemical impedance spectroscopy (EIS) associated…
The growth of Cobalt oxides by reactive thermal evaporation of metallic Cobalt in an oxygen atmosphere on a series of oxide substrates, namely SiO 2 , Al 2 O 3 and MgO, has been chemically and morphologically studied by means of XPS and atomic force microscopy (AFM). The XPS results reveal that cobalt oxide grows as C…
