Advances in Perovskite-Based Solar Cells

Olasunkanmi R. Kesinro、M. L. Akinyemi、A. O. Boyo2017-01-01Covenant University Repository (Covenant University)

The increase in energy demand due to increase in population and reduction of fossil fuels has led to the search of alternative energy sources. Solar energy, which is an alternative source of energy, has been in the fore front of this research. Various methods of converting solar energy into electricity has been attain…

Modeling the formation of collagen-mimetic triple helices and microfibrils

Vyshnavi S. Karra2017-01-01OpenAlex

Collagen is an abundant and integral protein within the body, due to its mechanical strength and elasticity. These properties arise from the structural hierarchy of collagen, from the peptide strands, to tropocollagen, to microfibrils, to fibers. Understanding the formation mechanisms of collagen can aid in the resear…

Magnesium-selective ligands in luminescence-based systems

Edward Robert Henry Walter2017-01-01Durham e-Theses (Durham University)

Magnesium is the most abundant divalent cation in vivo. Despite this, Mg2+ homeostasis remains poorly understood compared to other biologically relevant cations. Literature-based chelates lack structural variety, with a number of intrinsic problems limiting their applications in vivo. The o‑aminophenol-N,N,O-triacetic…

Non-periodic Metasurfaces for Blazing and Metasurface Assisted Leaky Waveguide

T.C.E. Cheng2017-01-01eScholarship (California Digital Library)

In the first part of this thesis, non-periodic metasurfaces are explored to realize blazing effects under oblique plane-wave illumination. Genetic Algorithm is used to optimize the surface’s local reflection phase over the entire finite aperture, for a particular scattering response (e.g. blazing). Such non-periodic a…

Kartläggning av ventiler innehållande Stellite i reaktornära vattensystem på Forsmark 2

Daniel Ohlsson2017-01-01KTH Publication Database DiVA (KTH Royal Institute of Technology)

In the process of a boiling water reactor, high-levels of waste and radiation occur, where almost all the dose per person of the radiation in Forsmark are due to the radioactive iso-tope cobalt-60. The reason is that the stable isotope cobalt-59 is converted to the radioac-tive isotope cobalt-60 due to neutron irradia…

Hellinger-Reissner variational principle for stress gradient elastic bodies with embedded coherent interfaces

Guido Borino、Francesco Parrinello、Castrenze Polizzotto2017-01-01Nova Science Publishers (Nova Science Publishers, Inc.)

An Hellinger-Reissner (H-R) variational principle is proposed for stress gradient elasticity material models. Stress gradient elasticity is an emerging branch of non-simple constitutive elastic models where the infinitesimal strain tensor is linearly related to the Cauchy stress tensor and to its Laplacian. The H-R pr…
