The understanding of cell-cell and cell-matrix interactions via receptor and ligand binding relies on our ability to study the very first events of their contact. Of particular interest is the interaction between a T cell receptor and its cognate peptide-m ...

Porous brittle solids evidence complex mechanical behavior, where localized failure patterns originate from mechanical processes on the microstructural level. In order to investigate the failure mechanics of porous brittle solids, we outline a general stoc ...

The design of energy pile is hampered by the complex interaction between the piles and the slab subjected to thermal loads. Although finite element analysis is used to account explicitly for the interactions, this method is mainly considered as a research ...

Strain Hardening Ultra High Performance Fiber Reinforced Concretes (SH-UHPFRC) are cementitious materials with exceptional mechanical properties and outstanding durability making them ideal materials for rehabilitation, for the improvement of load carrying ...

Spurred by developments in digital fabrication, there has been an increase in the application of the Integral Mechanical Attachment (IMA) technique in timber plate structures. Despite its increase in popularity, there have been very few systematic investig ...

Over the last fifty years, the interaction factor method has been widely used to address the vertical displacement and the increased deformation of conventional pile groups subjected to mechanical loads when group effects and interactions occur among the p ...

The baseline configuration of the Compact Linear Collider (CLIC) foresees an electron beam with 80% polarization at the interaction point (IP) to be measured with an accuracy of 0.1%. The propagation of the polarization through the CLIC beam delivery syste ...

Seismic assessment of unreinforced masonry structures remains a challenge. This dissertation investigates the in-plane behavior of historical masonry elements and proposes an advanced simulation method based on the cohesive zone model (CZM) in a finite ele ...

Prior to this study, no simplified yet rational methods were available for estimating the vertical displacements of energy pile groups subjected to thermal loads. Observing such a challenge, the goal of this study has been threefold: (i) to extend the inte ...

This study investigates the thermally induced mechanical interactions among closely spaced energy piles that partially operate as geothermal heat exchangers over a time-scale that is typical of practical applications. The analysis is based on the results o ...

We reveal a strong elastic interaction between nonferroelastic domain walls in ferroelectric thin films. This interaction, having no analogue in bulk materials, is governed by elastic fields that are associated with the domain walls and extends to distance ...

The problem of mechanical contact is a truly multiscale one. Atomistic effects that violate continuum theory dominate the deformations of contacting asperities, while the interactions between distant asperities occur through long-range elasticity. This the ...

Energy piles are an effective and economic means of using geothermal energy resources for heating and cooling buildings, contributing to legislative requirements for renewable energy in new construction. While such piles have been used for around 25 years ...

An unprecedented series of titanocene-gold bi- and trimetallic complexes of the general formula [(eta(5)-C5H5)-(mu-eta(5):kappa(1)-C5H4(CH2)(n)PPh2)TiCl2AuClx](q+) (n = 0, 2, or 4; m = 1, x =1, q = 0 or m = 2, x = 0, q = 1) have been prepared and char ...

Multiscale modeling, including molecular dynamics (MD) and discrete dislocation dynamics (DDD) methods, appears as a signiﬁcant tool for the description of plasticity and mechanical properties of materials. This research concerns the inﬂuence of irradiatio ...

Particle aggregation is a commonly observed phenomenon in many types of soils, such as natural clays and agricultural soils. These soils contain porous aggregates, often separated by large, interaggregate pores. Two levels of intra- and interaggregate poro ...

Hot tearing is one of the most severe defects observed in castings, e.g. in billets or sheet ingots of aluminum alloys produced by DC casting. It is due to both tensile strains and a lack of interdendritic feeding in the mushy zone. In order to predict thi ...

Interaction of N2O at low temps. (473-603 K) with Fe-ZSM-5 zeolites (Fe, 0.01-2.1 wt%) activated by steaming and/or thermal treatment in He at 1323 K was studied by the transient response method and temp.-programmed desorption (TPD). Diffuse reflectance IR ...

This thesis explores the processing and properties of microcellular aluminium-based materials produced by replication. It includes the development of a pressure infiltration process for net-shape component production, structural characterization of the foa ...

We numerically study the dependence of the dynamics on the range of interaction Δ for the short-range square well potential. We find that, for small Δ, dynamics scale exactly in the same way as thermodynamics, both for Newtonian and Brownian microscopic dy ...
