Unique thermal properties of metal clusters are believed to originate from the hierarchy of the bonding. However, an atomic-level understanding of how the bond stiffnesses are affected by the atomic packing of a metal cluster and the interfacial structure with the surrounding environment has not been attained to date.…
Superparamagnetic FeCo nanochains consisting of assembled ∼25 nm nanoparticles and ∼1 nm gaps are synthesized by facial wet-chemical route and exhibit significant electromagnetic absorption at gigahertz. Both the dielectric and magnetic loss factors present dual-resonance behaviors at 2-18 GHz frequencies, originated…
In search of functional molecular materials and the study of their formation mechanism, we report the elucidation of a hierarchical step-by-step formation from monomer (Mn) to heptamer (Mn7) to nonadecamer (Mn19) satisfying the relation 1 + Σn6n, where n is the ring number of the Brucite structure using high-resolutio…
We report on the electrical characterization of single MXene Ti3C2Tx flakes (where T is a surface termination) and demonstrate the metallic nature of their conductivities. We also show that the carrier density can be modulated by an external gate voltage. The density of free carriers is estimated to be 8 ± 3 × 1021 cm…
It is generally recognized that nanoparticles possess unique physicochemical properties that are largely different from those of conventional materials, specifically the electromagnetic properties of magnetic nanoparticles (MNPs). These properties have attracted many researchers to launch investigations into their pot…
Raman spectroscopy is among the primary techniques for the characterisation of graphene materials, as it provides insights into the quality of measured graphenes including their structure and conductivity as well as the presence of dopants. However, our ability to draw conclusions based on such spectra is limited by a…
Abstract This is a review article on the current status and future prospects of the research and development on gallium oxide (Ga 2 O 3 ) power devices. Ga 2 O 3 possesses excellent material properties, in particular for power device applications. It is also attractive from an industrial viewpoint since large-size, hi…
Microstructure reconstruction and compression techniques are designed to find\na microstructure with desired properties. While the microstructure\nreconstruction searches for a microstructure with prescribed statistical\nproperties, the microstructure compression focuses on efficient representation\nof material morpho…
A new versatile facility LEETECH for detector R&D, tests and calibration is designed and constructed. It uses electrons produced by the photoinjector PHIL at LAL, Orsay and provides a powerful tool for wide range R&D studies of different detector concepts delivering "mono-chromatic" samples of low energy electrons wit…

El presente trabajo se basa en el desarrollo de un proceso para la extraccion en frio de quitina y produccion de quitosano a partir de desechos de exoesqueletos de camaron determinando la cantidad optima de acido clorhidrico concentrado usado en el proceso de extraccion de la proteina que posteriormente fue empleada c…
Let $K$ be a convex body. It is known that, in general, if $K$ is a $k$-fold translative tile (for some positive integer $k$), then $K$ may not be a (onefold) translative tile. However, in this paper I will show that for every convex body $K$, $K$ is a twofold translative tile if and only if $K$ is a translative tile.

In this article, we study the emergence of polarization singularities in the scattered fields of optical resonators excited by linearly polarized plane waves. First, we prove analytically that combinations of isotropic electric and magnetic dipoles can sustain L surfaces, and C lines that propagate from the near-field…
To improve enzymatic digestibility and sugar concentration, sweet sorghum bagasse was pretreated with alkali and liquid hot water, and then subjected to fed-batch enzymatic hydrolysis. Scanning electron microscopy assay suggested that different pretreatment methods resulted in different composition and structure of re…
Using chicken embryos it is possible to test directly the effects of either growth factors or specific inhibitors of signaling pathways on gene expression and activation of signal transduction pathways. This technique allows the delivery of signaling molecules at precisely defined developmental stages for specific tim…
Solvent-base paint industries moreover to hazardous solid wastes, volatile organic compounds and air emissions produce significant amount of wastewater containing organic solvents which are classified as hazardous wastes due to toxicity, ignitability or both. These wastes have adverse impacts on human health and natur…
Europium trivalent (Eu\(\mbox{} ^{3+}\), 2%) doped Y\(_2\)O\(_3\) nanophosphors were synthesized by solgel method and annealed at temperature 600 \(^\circ\)C and 900 \(^\circ\)C. The phosphors were characterized by XRD, FTIR, UV-visible and PL spectroscopy. The average crystal size was in the range of 10-26 nm. FTIR s…
Resumo Este trabalho teve como objetivo determinar o efeito da inclusão de óleos essenciais (EOs) e do armazenamento na cor dos filmes de quitosana (CH) para os parâmetros de L*, a*, b* e ΔE. Os óleos essenciais de tomilho (TEO) e alecrim (REO) foram incluídos em concentrações de 0,5:1 e 1:1 p/p (EOs:CH), assim como s…
