Manipulation of emission energy in GaAs/AlGaAs core-shell nanowires with radial heterostructure
(American Institute of Physics - AIPCollege Park, 2014)
Photoluminescence was studied in GaAs/AlGaAs nanowires (NWs) with different radial heterostructures. We demonstrated that manipulation of the emission energy may be achieved by appropriate choice of the shell structure. ...
Microstructure and crystallographic-texture of giant barnacle (Austromegabalanus psittacus) shell
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2006-11)
Barnacle shell is a very complex and strong composite bioceramic composed of different structural units which consist of calcite 15
microcrystals of very uniform size. In the study reported herein, the microstructural ...
Optical and structural investigation of ZnO@ZnS core-shell nanostructures
(2016-04-15)
In the present work, are reported the experimental study of ZnO@ZnS core-shell synthesised by a microwave-assisted solvothermal (MAS) method. Some synthesis parameters such as, time, precursor concentration and temperature ...

Molecular structure and bonding of copper cluster monocarbonyls CunCO (n=1-9)
(AMER CHEMICAL SOC, 2006)
In this work we analyze CO binding on small neutral copper clusters, Cu-n (n = 1-9). Molecular structures and reactivity descriptors of copper clusters are computed and discussed. The results show that the condensed Fukui ...
Core-Shell Nanoparticles and Three-Dimensional Nanostructured Materials as Electrocatalysts for Direct Alcohol Fuel Cells: How to Use Less Platinum and Not Die Trying
(Nova Science Publishers, 2019)
Today, the major challenges that have to be overcome for a massive production and commercialization of direct alcohol fuel cell (DAFC) technologies for stationary, portable and transportation applications are the high cost ...
Iron Oxide Versus Fe55Pt45/Fe3O4: Improved Magnetic Properties of Core/Shell Nanoparticles for Biomedical Applications
(Institute of Electrical and Electronics Engineers (IEEE), 2014)
Multi-shell spherical GaAs/AlxGa(1-x)As quantum dot shells-size distribution as a mechanism to generate intermediate band energy levels
(Elsevier, 2017-04)
In this work the generation of an intermediate band of energy levels from multi-shell spherical GaAs/AlxGa(1-x)As quantum dot shells-size distribution is reported. Within the effective mass approximation the electronic ...
Generation of engineered core-shell antibiotic nanoparticles
(Facultad de Ingeniería y Tecnología, 2019)
Well-defined nanocomposite structures have received significant attention due to their superior combinatorial properties. Rational tuning of the core and shell of the nanostructure(s) can offer potent antibacterial activity. ...
