Oxygen passivation as effective technique for tailoring the nature of band gap of silicon nanowires
(
Institute of Electrical and Electronics Engineers Inc. (IEEE)
, 2015 , Conference Paper)
Silicon nanowires have been subjected to several experiential and theoretical studies, including chemical tuning with different substituents aiming to tailor the band gap as well as increasing optical absorption efficiency ...
CO2 Reduction to Renewable Hydrocarbon Fuel - Mimicking Natural Photosynthesis
(
Springer Nature
, 2017 , Article)
We report on a wide-range Density Functional Theory (DFT) investigation of the g-C3N4 photocatalysis systems combined with metals/nonmetals, especially those available in plants and involved in the natural photosynthesis ...
Macro-scale direct shear test device for assessing soil-solid interface friction under low effective normal stresses
(
ASTM International
, 2014 , Article)
The paper describes a new macro-scale direct shear test device for assessing the largedisplacement soil/solid interface drained shear strength at low effective normal stresses. The testing method arises from a need to ...
Shear strength of geosynthetic composite systems for design of landfill liner and cover slopes
(
Elsevier
, 2011 , Article)
Torsional ring shear tests were performed on composite specimens that simulate the field alignment of municipal solid waste (MSW) landfill liner and cover system components. Simultaneous shearing was provided to each test ...
Numerical study on settlement of piled foundations on homogenous rock
(
Taylor and Francis
, 2014 , Conference Paper)
Settlement behavior of piled foundations on homogenous rock was investigated using an extensive three-dimensional finite element analysis of different piled-foundation models. Effects of pile slenderness ratio, pile spacing, ...
Settlement of axially loaded piles entirely embedded in rock - analytical and experimental study
(
Taylor and Francis
, 2012 , Article)
Finite element analysis was performed to study the settlement behaviour of axially loaded piles entirely embedded in nonhomogenous rock. The elastic modulus of the rock mass was taken to increase linearly along the pile ...
Two- and three-dimensional analyses of translational slides in soils with nonlinear failure envelopes
(
Canadian Science Publishing
, 2010 , Article)
This paper aims to assess the effect of nonlinearity of the soil shear strength envelope on the sliding mass con-figurations and the minimum two- and three-dimensional factors of safety for slopes susceptible to translational ...
Residual shear strength of fine-grained soils and soil-solid interfaces at low effective normal stresses
(
Canadian Science Publishing
, 2015 , Article)
A laboratory research program was undertaken to study the large-strain shear strength characteristics of fine-grained soils under low effective normal stresses ([1]3-7 kPa). Soils that cover a wide range of plasticity and ...
Laboratory testing of full-scale pipes partially embedded in soil to study soil-pipe interaction of offshore seabed oil and gas pipelines - Initial observations
(
American Society of Mechanical Engineers (ASME)
, 2014 , Conference Paper)
The geotechnical aspect of the design of off-shore oil and gas pipelines is a challenge due to inherent uncertainties in predicting soil-pipe interaction behaviour. Physical modeling is often sought after to gain insight ...
Geotechnical considerations on the design of piled rafts on rock
(
Research Publishing Services
, 2011 , Conference Paper)
This research shows the effect of misestimating the pile spring constant (Kpl) and the modulus of subgrade reaction (Ksg) on design of piled rafts on rock. The high mass stiffness of rock contacting the base of such rafts ...
