NANOPATTERNING OF FREE-STANDING VAN DER WAALS HETEROSTRUCTURES USING CHARGED PARTICLES
Lateral confinement in two-dimensional (2D) transition metal dichalcogenides (TMDs) enables one-dimensional structures with tunable band structures, offering new opportunities in nanophotonics and optoelectronics. However, achieving such confinement with high spatial and depth resolution in stacked …

Wave propagation in one dimensional confined granular media
… to consider the effects of different types of lateral confinement on the dynamic response of such one dimensional granular chains. Chains of metallic beads are placed under lateral confinement in one of two ways: (a) by having a metal tube with a diameter mismatch shrink fit around the chain …

Axial load capacity of circular steel tube columns filled with high strength concrete
… capacity of short columns attributed to the lateral confinement of the concrete infill provided by the steel encasement. The degree of confinement has been found to be dependent on several geometric and mechanical parameters. At present, significant discrepancies exist with respect to …

A Design Approach for Seismic Retrofit of Circular Bridge Columns With Lap Splices
… in order to study the optimal amount of lateral confinement necessary to avoid a lap splice failure, the influence of the bar orientation in the retrofitting of the columns, and to assess the different retrofitting techniques. Eight half size models were built with characteristics similar …

Finite Element Method Modeling Of Advanced Electronic Devices
… with multi-step discontinuities and soft wall lateral confinement. Radiation mechanism and conditions are examined by numerical simulation of dispersion relations and transport properties. The study of geometry variations shows its significant impact on the radiation intensity and direction. In …

Swelling behaviour of unsaturated fine grained soils
… pressure of the soil under conditions of lateral confinement. The results show that the swelling behaviour of these soils is controlled by the testing conditions imposed on the soil as well as the initial state of the soil as described by dry density and water content. Suction measurements …

Laterally confined THz sources and graphene based THz optics
… of the hot electrons. Theoretical studies in laterally confined QCL structures have predicted enhanced lifetime of the upper state through suppression of the non-radiative intersubband relaxation of carriers, which leads to lower threshold, and higher temperature performance. Lithographically …

Identification, Mapping, Analysis, and Dating of Composite Mega Landslides in the Colorado Plateau
… susceptible to creep and strain softening where lateral confinement has been removed by the downcutting of the Colorado River and its tributaries. Strata dipping towards valleys, including dips of 5 degrees or less, greatly impact the number and scale of landslide events. The over consolidated …

Elastomer Degradation in Chemically Reactive Environment under Elevated Temperature and Pressurized Condition
… that for elastomer stress relaxation, additional lateral confinement induced by environmental stress can effective reduce elastomer relaxation along the axial direction. In addition to the development of experimental elastomer characterization methodology, we also built a quantitative model to …

Exploring and exploiting charge-carrier confinement in semiconductor nanostructures : heterodimensionality in sub-monolayer InAs in GaAs and photoelectrolysis using type-II heterojunctions
… important technologies. Firstly, charge-carrier confinement in stacked sub-monolayer (SML) InAs in GaAs: SML deposition results in the formation of In-rich agglomerations within a lateral InGaAs quantum well (QW) with lower In content. Low-temperature photoluminescence (PL) and magneto-PL reveals …

Probabilistic seismic demand models of RC bridge columns retrofitted with shape memory alloy spirals
… these vulnerable RC bridge columns by applying lateral active confinement using shape memory alloy (SMA) spirals can significantly improve their ductility, resulting in enhanced seismic performance. The research work done till date in this area is limited to exploring experimentally the efficacy …

Seismic characterization of recycled aggregate concrete
… The columns with sufficient and well-distributed lateral confinement did not also show any stiffness degradation under cyclic loading. Special attention was paid to recording the axial strains at which vertical cracks were developing, as well as the strains at which the cover was no longer …
