Quantum computing based on semiconductor nanowires

Frolov, S.M. (author), Plissard, S.R. (author), Nadj-Perge, S. (author), Kouwenhoven, L.P. (author), Bakkers, E.P.A.M. (author)

A quantum computer will have computational power beyond that of conventional computers, which can be exploited for solving important and complex problems, such as predicting the conformations of large biological molecules. Materials play a major role in this emerging technology, as they can enable sophisticated operations, such as control over...

Active suspensions in thin films: Nutrient uptake and swimmer motion

Lambert, R.A. (author), Picano, F. (author), Breugem, W.P. (author), Brandt, L. (author)

A numerical study of swimming particle motion and nutrient transport is conducted for a semidilute to dense suspension in a thin film. The steady squirmer model is used to represent the motion of living cells in suspension with the nutrient uptake by swimming particles modelled using a first-order kinetic equation representing the absorption...

Origin(s) of Antarctica's Wilkes subglacial basin

Weihaupt, J.G. (author), Van der Hoeven, F.G. (author), Lorius, C. (author), Chambers, F.B. (author)

The Wilkes Subglacial Basin (WSB), the largest subglacial basin in East Antarctica, is a topographic depression of continental proportions that lies beneath the East Antarctic continental ice sheet. Discovered by the US Victoria Land Traverse 1959–60, the origin of the WSB and the influence of palaeoclimate on its overlying continental ice sheet...

In Situ transmission electron microscopy imaging of electromigration in platinum nanowires

Rudneva, M. (author), Gao, B. (author), Prins, F. (author), Xu, Q. (author), Van der Zant, H.S.J. (author), Zandbergen, H.W. (author)

In situ transmission electron microscopy was performed on the electromigration in platinum (Pt) nanowires (14 nm thick, 200 nm wide, and 300 nm long) with and without feedback control. Using the feedback control mode, symmetric electrodes are obtained and the gap usually forms at the center of the Pt nanowire. Without feedback control,...

Precise and faster GNSS signal direction of arrival estimation

Sun, R. (author), O'Keefe, K. (author), Guo, J. (author), Gill, E. (author)

This paper proposes a precise and fast direction of arrival estimation method using Global Navigation Satellite System (GNSS) carrier phase measurements. Single-epoch, single-satellite integer cycle ambiguities are reliably resolved by making use of constraints and taking advantages of antenna arrays. The algorithm shows good robustness in cases...

The coexistence of engineering meanings of function: Four responses and their methodological implications

Vermaas, P.E. (author)

In this position paper, the ambiguity of functional descriptions in engineering is considered from a methodological point of view. Four responses to this ambiguity are discussed, ranging from defining a single meaning of function and rejecting the different meanings that are currently used in engineering to accepting these meanings as coexisting...

Metal hydrides for smart window and sensor applications

Yoshimura, K. (author), Langhammer, C. (author), Dam, B. (author)

The hydrogenation of metals often leads to changes in optical properties in the visible range. This allows for fundamental studies of the hydrogenation process, as well as the exploration of various applications using these optical effects. Here, we focus on recent developments in metal hydride-based optical fiber and plasmonic sensors and smart...

Diamond NV centers for quantum computing and quantum networks

Childress, L. (author), Hanson, R. (author)

The exotic features of quantum mechanics have the potential to revolutionize information technologies. Using superposition and entanglement, a quantum processor could efficiently tackle problems inaccessible to current-day computers. Nonlocal correlations may be exploited for intrinsically secure communication across the globe. Finding and...

Dynamics of droplet breakup in a T-junction

Hoang, D.A. (author), Portela, L.M. (author), Kleijn, C.R. (author), Kreutzer, M.T. (author), Van Steijn, V. (author)

The breakup of droplets due to creeping motion in a confined microchannel geometry is studied using three-dimensional numerical simulations. Analogously to unconfined droplets, there exist two distinct breakup phases: (i) a quasi-steady droplet deformation driven by the externally applied flow; and (ii) a surface-tension-driven three-dimensional...

Automated podosome identification and characterization in fluorescence microscopy images

Meddens, M.B.M. (author), Rieger, B. (author), Figdor, C.G. (author), Cambi, A. (author), Van den Dries, K. (author)

Podosomes are cellular adhesion structures involved in matrix degradation and invasion that comprise an actin core and a ring of cytoskeletal adaptor proteins. They are most often identified by staining with phalloidin, which binds F-actin and therefore visualizes the core. However, not only podosomes, but also many other cytoskeletal structures...

Turbulent drag reduction using fluid spheres

Gillissen, J.J.J. (author)

Using direct numerical simulations of turbulent Couette flow, we predict drag reduction in suspensions of neutrally buoyant fluid spheres, of diameter larger than the Kolmogorov length scale. The velocity fluctuations are enhanced in the streamwise direction, and reduced in the cross-stream directions, which is similar to the more studied case...

A method to reduce ambiguities of qualitative reasoning for conceptual design applications

D'Amelio, V. (author), Chmarra, M.K. (author), Tomiyama, T. (author)

Qualitative reasoning can generate ambiguous behaviors due to the lack of quantitative information. Despite many different research results focusing on ambiguities reduction, fundamentally it is impossible to totally remove ambiguities with only qualitative methods and to guarantee the consistency of results. This prevents the wide use of...

Interphasial energy transfer and particle dissipation in particle-laden wall turbulence

Zhao, L. (author), Andersson, H.I. (author), Gillissen, J.J.J. (author)

Transfer of mechanical energy between solid spherical particles and a Newtonian carrier fluid has been explored in two-way coupled direct numerical simulations of turbulent channel flow. The inertial particles have been treated as individual point particles in a Lagrangian framework and their feedback on the fluid phase has been incorporated in...
