Subwavelength gratings for sensing and polarization management
Sub-wavelength grating (SWGs) structures are becoming important building blocks in planar waveguide photonic devices [1]. SWG structures have been successfully applied in the design of a range of devices with remarkable performance by using refractive index engineering and dispersion engineering techniques [2]. In thi…

A comparative study between Direct Spinel Addition and In- Situ Spinelisation in a Low Cement High Alumina based Refractory Castable
Spinel containing castables are becoming widely popular due to their high slag resistance, spalling resistance, drying behavior and hot strength. Most of the steel plants today use Magnesia-Alumina spinel system (MgAl2O4). Spinel containing castables can be prepared by two methods: direct spinel addition and in-situ s…

Nickel-Seeded Silicon Nanowires Grown on Graphene as Anode Material for Lithium Ion Batteries
There is a growing interest for relying on cleaner and more sustainable energy sources due to the negative side-effects of the dominant fossil-fuel based energy storage and conversion systems. Cleaner, electrochemical energy storage through lithium-ion batteries has gained considerable interest and market value for ap…
Preparação e caracterização de elastômeros reticulados dinamicamente de PA6-12/EVA
Materiais poliméricos que possuam boas propriedades mecânicas aliadas à flexibilidade são requisitos para atender novas necessidades da indústria. Tais necessidades podem ser atingidas com a produção de elastômeros termoplásticos vulcanizados/reticulados dinamicamente (TPVs). Os TPVs são produzidos normalmente a parti…
Scalar wave scattering by two-layer radial inhomogeneities
It is known that the Jost-function formulation of quantum scattering theory can be applied to classical problems concerned with the scattering of a plane scalar wave by a medium with a spherically symmetric inhomogeneity of finite extent. This technique is applied to solve the radial differential equation for the scat…
Carbon Nanotube Electrochemical Detectors in Microfluidics
Microarray technology is constantly evolving to meet new demands for research tools, sensors, and bioinformatics. Particularly, the detection of multiple classes of biomarkers on a single platform has the ability to advance areas, such as genomics and proteomics, where high throughput and large data sets are outpacing…
Desenvolvimento de compósitos com base em rejeito de tecidos de algodão e acrílico em matriz de polietileno de alta densidade
Compósitos de polietileno de alta densidade (HDPE) com resíduos de fibras têxteis com propriedades mecânicas otimizadas foram desenvolvidos buscando viabilizar o reaproveitamento desses resíduos. Para tanto, foram utilizados resíduos contendo fibras de algodão e fibra acrílica, provenientes do setor de tecelagem da in…
CLAY MINERALOGY OF LITHOFACIES OF NORTHLAND ALLOCHTHON ROCKS, NORTH ISLAND, NEW ZEALAND
Northland Allochthon, a bathyal depth sediments, comprises an originally fining-upwards passive margin wedge which accumulated adjacent to northeastern New Zealand between mid-Cretaceous and latest Oligocene. The Northland Allochthon is overlain by Miocene arc and arc-basin deposits. This paper provides clay mineralog…
Temperature Dependent Time-Resolved Fluorescence in Au25 Nanoclusters
Fluorescent gold nanoclusters have attracted considerable interest for fundamental research and practical applications. Herein we study the optical properties of Au25 nanoclusters protected by glutathione (GSH) using temperature dependent time-resolved fluorescence. We elucidate that the fluorescence of Au25 dominantl…
A superconducting magnet feeder system that avoids the risk of Paschen discharge
Current is traditionally fed to magnets in fusion devices via a system of superconducting busbars in a thermally insulating vacuum enclosure. Some of the magnets are pulsed, taking the busbars to a potential of several kilovolts, so these must be well insulated electrically. There is a risk of helium leaking into the…
The use of carbon molecule sieve and Pd membranes for conventional and reactive applications
High-temperature gas separations using inorganic membranes have attracted increased attention in recent years. In particular, the use of such membranes in high?temperature and high?pressure membrane reactors has the potential to enhance process intensification and to increase energy savings and/or product yield. Thoug…
