Planar Chiral MetaMaterials structures, based on mutually twisted faces or conjugated faces, with C4 symmetry, may present high optical activity but low circular dichroism values. In this communication, an Asymmetric CMM structure with high circular dichroism is proposed. Due to its lack of C4 symmetry, the transmissi…
Abstract In this paper, we describe measurements of the cathodoluminescence of nanosized cubic Y 2 O 3 :Tb 3+ with a transmission electron microscope. From the CL‐spectra we determined the energy flow from excited Tb 3+ in a S 6 lattice site to Tb 3+ in a C 2 site.
fully biobased polymer which utilizes a novel chemical structure, as opposed to ‘drop-in’ biobased polymers. However, it is a relatively brittle plastic, which limits its application areas. Therefore, ongoing research is developing high-impact PLA (HIPLA) through compounding with additives or copolymerisation , aiming…
In the present work, Polypropylene (PP) was blended with poly methyl methacrylate (PMMA) to form (PP/PMMA) polymer blends. High Density Polyethylene (HDPE) was mixed into these blends at different weight fractions (2,4,6,8) % wt to form (PP/PMMA/HDPE) blends were prepared using an one screw extruder. results obtained…
Photonic structure plays a significant role in determining the brightness and efficiency of nanoemitter systems. Using photonic crystal slabs it is possible to affect these quantities in various ways. First, positioning a leaky mode near the emission frequency allows more light to be extracted from within the slab. Se…
Sub-diffractional confinement of light has led to advancements in imaging, metamaterials, nano-manufacturing, plasmonics, and other fields. One potential route to sub-diffractional confinement is via stimulated surface phonon polaritons (SPhPs). SPhPs couple infrared photons with optical phonons and consequently their…
We show experimentally that wavefront - the direction, spectral composition and phase profile of light emission - stimulated by free electron injection into plasmonic and dielectric media can be controlled with high finesse using holographic nanostructures.
In this study the effect of nano sized silica particles (nano-SiO2) on the physical and mechanical properties of rice husk and Old Corrugated Container (OCC)-cement boards was investigated. Modulus Of Rupture (MOR), Modulus Of Elasticity (MOE), Internal Bonding Strength (IB), density, water absorption and thickness sw…
Abstract This work describes the manufacture and performance of an electrochromic display with solution‐based processing. The presented process yields devices with very high life times of more than 100,000 cycles even when switched asymmetrically (with respect to time).
Abstract : This report contains information regarding the feasibility studies conducted by Nanosyntex during the US Army BAA project to design and develop a Fire Resistant (FR) and Heat Resistant (HR) sewing thread. The main goal of the project is to produce sewing threads made of blends of high performance and commod…
Nanoscale integration of materials in three dimensions is critical for the realization of a number of highly functional optical metamaterials. Starting with structures enabled via eutectic solidification and holographic lithography, our team is applying unique template-based and post-synthetic materials transformation…
The question considered is the approximation of problem-solving results for the deformable solids me-chanics through finite differences with MathCAD built-in functions. It is shown that the most acceptable approximant in a MathCAD package for deformable solid mechanics problem-solving when required parameters express…
The concept of symmetry pervades modern physics. Through the conservation laws derived from various symmetries, high-level restrictions and selection rules can be derived for a variety of physical systems without any need for detailed investigations of their specific properties. The spatial symmetries of electric char…
A new model was proposed to describe the behavior of melts and concentrated solutions of polymers at high strain rates. This model is a lattice of elastic elements, which, under deformation, transform into ellipsoids, are oriented, and elastically interact with each other. The calculation results give a qualitatively…
The present study aims to detect morphological abnormalities in Zygnema sp. because this test species have high adaptive capacity in unfavourable environmental stress. This alga is inhabited at the suburban bank of river Ganga, West Bengal, India. The study was done at experimental sites, downstream at Khardah near se…
Plasmonics is promising for future electronics as it can combine optical speed of operation with nanoscale size, something which is not possible with traditional optics and electronics [1]. Coupling of photons, plasmonic excitations and electrons is of key importance as it provides opportunities to monitor or control…
Defects in the metal structure of the rubbing surfaces (pores, fractures, and dislocations) are considered to be magnetic traps for hydrogen and impurity elements. As a result of the interaction of hydrogen with carbon, not only is methane formed in the metal, but also other hydrocarbon homologous (from ethane to hexa…
Transition metal dichalcogenides (TMDs) have emerged as an attractive class of two-dimensional (2D) semiconductors that show unprecedented strength in its interaction with light. Here we will discuss our recent work on embedding such a 2D TMD layer of molybdenum disulphide in a dielectric microcavity showing the formi…
Bulk metallic glasses synthesized at specialized facilities at Yale using magnetron cosputtering are sent to Southern Connecticut State University for elemental characterization. Characterization is done using a Zeiss Sigma VP SEM coupled with an Oxford EDS. Characterization is automated using control software provide…
