We demonstrate efficient guided-mode resonant polarization-controlled tunable color filters. The devices consist of subwavelength gratings that are partially etched into a thin silicon-nitride film deposited on a glass substrate. Two color filters with grating periods of 300 nm and 370 nm are designed and fabricated.…
Because of their considerable science and technical interest, nanodiamonds (3-5 nm) are often used as a model to study the phase transformation between graphite and diamond. Here we demonstrated that a reversible nanodiamond-carbon onion phase transformation can become true when laser irradiates colloidal suspensions…
Recent advances in creating complex oxide heterostructures, interfaces formed between two different transition-metal oxides, have heralded a new era of materials and physics research, enabling a uniquely diverse set of coexisting physical properties to be combined with an ever-increasing degree of experimental control…
In the field of hydrolysis of sodium borohydride, most of the works deal with metal-based catalysis and catalytic performance. Knowledge of reaction mechanisms, especially when a cobalt-based catalyst is used, is limited. This review has therefore two objectives. It aims at surveying the reaction paths and the related…
Exposure to the EGFR (epidermal growth factor receptor) inhibitor erlotinib promotes the dynamic rewiring of apoptotic pathways, which sensitizes cells within a specific period to subsequent exposure to the DNA-damaging agent doxorubicin. A critical challenge for translating this therapeutic network rewiring into clin…
A novel free-standing and flexible electrospun carbon-silica composite nanofibrous membrane is newly introduced. The characterization results suggest that the electrospun composite nanofibers are constructed by carbon chains interpenetrated through a linear network of 3-dimensional SiO2. Thermogravimetric analysis ind…
Field-effect transistor (FET) devices composed of a MoS2-graphene heterostructure can combine the advantages of high carrier mobility in graphene with the permanent band gap of MoS2 for digital applications. Herein, we investigate the electron transfer, photoluminescence, and gate-controlled carrier transport in such…
The electronic properties of colloidal quantum dots (QDs) are critically dependent on both QD size and surface chemistry. Modification of quantum confinement provides control of the QD bandgap, while ligand-induced surface dipoles present a hitherto underutilized means of control over the absolute energy levels of QDs…
Nanoparticle incorporation is a convenient way to enhance the mechanical properties of polymer matrices. In the last number of years abundant research has been done published concerning the enhancement of the mechanical properties of nanoparticle filled polymers. This work analyses the influence of nano clay and nano…
Dicalcium phosphate anhydrous (DCPA) powder was synthesized in the size range between 200- 750 nm using calcium carbonate and phosphoric acid in ethanol solution. The X-ray diffraction pattern of the synthesized powder showed monetite as the major phase with some unreacted calcium carbonate as secondary phase. After 2…
Le procede de mise en forme des toles metalliques, generalement oxydees, par emboutissage est en pleine evolutionpour repondre a de nouveaux besoins : intervalles de tolerances dimensionnelles de plus en plus etroits, productionen grande serie a faible cout, apparition de nouvelles nuances de materiaux, souci ecologiq…

Dans les industries laitières, les procédés de transformation du lait conduisent à la formation de dépôts indésirables sur les parois des équipements. En raison du manque de solutions pour minimiser ces dépôts et assurer la sécurité et qualité des transformations, des procédures de nettoyage aux impacts économiques et…

The nitrogen depth profiles obtained from plasma nitrited CoCr alloy are analyzed by the stress induced diffusion model. The model considers diffusion of nitrogen under the influence of internal stresses created during nitriding process. Besides, this model is supplemented with concentration dependent nitrogen diffusi…
Guided mode resonance structures were fabricated and applied for on-line refractive index sensing. The method was applied for monitoring of biological reactions. Optical responds from the regular structures was simulated and explained employing different numerical solvers. The methods demonstrated better then 10-4 ref…
Liquid hydrogen (LH₂), which has large latent heat, low viscosity coefficient, is expected to be a candidate for a cryogen for superconducting wires, not only MgB₂ but also other HTC superconductors. LH₂ cooled superconducting wires are expected to have excellent electro-magnetic characteristics, which is necessary to…
Solid metals have previously been widely used for implant fabrication in the replacement of human hard tissues. For the implant-bone interface bonding newer materials are now-a-days being introduced with porosity. With tissue ingrowth into the porous structure of the implant this bonding has subsequently been enhanced…
