Surface-enhanced Raman scattering (SERS), owing to its high sensitivity based on localized surface plasmon resonance of nanostructured metals, is recently attracting much attention to be used for biotechnology, such as c...

Penelitian ini bertujuan untuk menjelaskan dan memahami bagaimana para pemeran tokoh Dewi Shinta dalam pertunjukan Sendratari Ramayana memaknai perannya. Sendratari merupakan suatu drama tari tanpa dialog dengan mengambi...

La participación comunitaria aplicada al campo de la salud puede entenderse como los diferentes alcances en los programas en referencia a la planificación, evaluación, control de acciones y servicios de salud hacia la...

Polymer composites of epoxy resin and Nb2O5 doped BaTiO3 were prepared in the form of film (thickness 30-300 μm) using a dipping technique. Samples containing various amounts of ceramic filler were examined by thermal a...

Analisou-se como as residências de Medicina de Família e Comunidade (RMFC) de uma capital da região norte do Brasil contribuíram para a formação e o desenvolvimento do atual processo de trabalho de seus egressos. E...

Apresenta-se um modelo de análise proposto por Jean-Marie Floch como possibilidade para a criação e avaliação da comunicação visual na área da saúde, especialmente em campanhas educativas. Parte-se de questões ...

Silver colloid based nanostructures are a very common means of achieving strong SERS signals. This is due to the hot spots that are formed in between the nanoparti‐ cles, as well as their ease of synthesis. They are fr...

Honey is one of the oldest sweetening foods and has economic importance, making this product attractive to adulteration with cheap sugars. This can cause a critical problem in the honey industry and a possible health ris...

A quick one-step fabrication of efficient SERS substrates by a modified approach based on a silver-mirror reaction (using Tollens’ reagent) is reported. Commercially available microscope slides or cover glass (coversli...

Surface-enhanced Raman scattering (SERS) substrates based on chemical mechanism (CM) have received widespread attentions for the stable and repeatable signal output due to their excellent chemical stability, uniform mole...

The molecular structure and conformational properties of 2,2,2-trichloroethyl chloroformate, ClC(O)OCH2CCl3 were determined experimentally using gas-phase electron diffraction (GED) and theoretically based on quantum-che...

Tip-based plasmonic nanofocusing, which delivers light into a nanoscale region and achieves localized electromagnetic (EM) field enhancement beyond the diffraction limit, is highly desired for light-matter interaction-ba...

The effect of synthesis temperature regimes on the structure and some physical properties of glassy germanium disulfide was examined using the methods of dilatometry and Raman scattering of light. It is concluded that th...

In pursuit of manufacturing of carbon nanotubes (CNTs) in good yield at lower temperatures, a mixture of d-block elements such as Iron, Nickel, and Cobalt was expected to be advantageous because of the high yield and low...

The ability of phytochromes (Phy) to act as photointerconvertible light switches in plants and microorganisms depends on key interactions between the bilin chromophore and the apoprotein that promote bilin attachment and...

Vanadium oxide thin films were fabricated using a multi-step deposition process involving magnetron sputtering and sequential annealing. The structural, vibrational, and nanomechanical properties of the films were invest...

The rechargeable lithium air (oxygen) battery (Li-O2) has very high energy density comparable to fossil fuels (∽3,600 Wh/kg). However, the parasitic reactions of the O2- reduction products with solvent and electrolyte ...

"Pulse propagation in nonlinear waveguides is most frequently modeled by resorting to the generalized nonlinear Schrödinger equation (GNLSE). In recent times, exciting new materials with peculiar nonlinear properties, s...

Metallic nanostructures with nanometer gaps support hybrid plasmonic modes with an extremely small mode volume and strong local field intensity, which constitutes an attractive plasmonic platform for exploring novel ligh...

Genipap (Genipa americana L., Rubiaceae ) is a native Brazilian species and can be used in the recovery of degraded forest areas or for food supply. In order for the species to reach its potential, production of high qua...

Ferrochelatases catalyze the insertion of ferrous iron into the porphyrin during the heme b biosynthesis pathway, which is fundamental for both prokaryotes and eukaryotes. Interestingly, in the active site of ferrochelat...

In this paper, the adsorption of trivalent chromium cations by a sample of sodium-modified TiO2 was studied. XRF analysis of the TiO2 surface was performed.  The dependence of the adsorption value on the duration of the...
