Hermeticity, reliability and strength of Al-Al thermocompression bonds realized by applying different bonding parameters have been investigated. Laminates of diameter 150 mm were realized by bonding wafers containing membrane structures to wafers with patterned bonding frames. The laminates were...

Nanoporous and nanowire structures based on silicon (Si) have a well recognized potential in a number of applications such as photovoltaics, energy storage and thermoelectricity. The immiscibility of Si and aluminum (Al) may be utilized to produce a thin film of vertically aligned Al nanowires of...

Modelling of wire-arc additive manufacturing process is an effective way for adapting the optimum parameters as well as understanding and managing the sequences of layer-by-layer deposition. Some of these parameters such as toolpath, deposition intervals and heat source power play important roles in...

Predictions of the anisotropic coefficients of thermal expansion are needed to not only compare to experimental measurement, but also as input for macroscopic modeling of devices which operate over a large temperature range. While most current methods are limited to isotropic systems within the...

We present a study of the surface effects and optical properties of the self-assembled nanostructures comprised of vertically aligned 5 nm-diameter Al nanowires embedded in an amorphous Si matrix (a-Si:Al). The controlled (partial) removal of Al nanowires in a selective etching process yielded...

The production of concrete for construction purposes is a major source of anthropogenic CO₂ emissions. One promising avenue towards a more sustainable construction industry is to make use of naturally occurring mineral-microbe interactions, such as microbial-induced carbonate precipitation (MICP...

The production of concrete is one of the most significant contributors to global greenhouse gas emissions. This work focuses on bio-cementation-based products and their potential to reduce global warming potential (GWP). In particular, we address a proposed bio-cementation method employing bacterial...

Calculations of thermoelectric transport coefficients including quantum effects are performed on superlattices using the Buttiker approximation. The results arecomparedto the Boltzmann transport equation withminibands present, and to an incoherent transport model. Comparisons are performed in the...

For the purpose of withstanding very high radiation doses, silicon pixel sensors with a ‘3D’ electrode geometry are being developed. Detectors of this kind are highly interesting for harch radiation environments such as expected in the High Luminosity LHC, but also for space physics and medical...

Nanostructured materials offer unique electronic and optical properties compared to their bulk counterparts. The challenging part of the synthesis is to create a balance between the control of design, size limitations, up-scalability and contamination. In this work we show that self-organized Al...

The role of hydrogen on intergranular (IG) fracture in hydrogen-assisted fatigue crack growth (HAFCG) of a pure iron at low stress intensity was discussed in terms of the microscopic deformation structures near crack propagation paths. The main cause of IG fracture was assumed to be the hydrogen...

Using monochromated electron energy loss spectroscopy in a probe-corrected scanning transmission electron microscope we demonstrate band gap mapping in ZnO/ZnCdO thin films with a spatial resolution below 10 nm and spectral precision of 20 meV....

The ZnCr2O4/ZnO materials system has a wide range of potential applications, for example, as a photocatalytic material for waste-water treatment and gas sensing. In this study, probe-corrected high-resolution scanning transmission electron microscopy and geometric phase analysis were utilized to...

The electrical, mechanical, and hermeticity properties of low-temperature, plasma activated direct silicon bonds were investigated. On individual dies with a bonding area ranging from 1–4 mm2, the bonded interface was found to have a capacitance ranging from 2.62 pF/mm2–2.89 pF/mm2 at 1 kHz. Linear...

Hermeticity, reliability and strength of four laminates bonded at different temperatures by Au-Au thermocompression bonding have been investigated. Laminates with a diameter of 150 mm were realized by bonding a wafer containing membrane structures to a Si wafer with patterned bond frames. A bond...

Proton-conducting electrolytes are candidates for a range of electrochemical applications. The search for one which may operate in the intermediate temperature range of 400-800 °C has been ongoing for a while, and Yttrium-doped BaZrO3 (BZY) have been established as one of the most promising...

Stereotactic Synchrotron Radiotherapy (SSRT) and Microbeam Radiation Therapy (MRT) are both novel approaches to treat brain tumor and potentially other tumors using synchrotron radiation. Although the techniques differ by their principles, SSRT and MRT share certain common aspects with the...

The objective of this study was to evaluate sperm quality of Duroc boars during sexual maturation and examine whether these parameters were related to metabolites in semen. Ejaculates were collected longitudinally from 28 Duroc boars at approximately 7 months of age (Age 1), 6 weeks later (Age...

Circular economy strategies, such as reusing load-bearing elements from obsolete buildings, can reduce the construction industry’s environmental impact. However, limited data on building composition often hinders implementation. Existing methods for estimating building composition are often...

BACKGROUND Non-verbal persons with intellectual disabilities (ID) may suffer from pain or discomfort, but caregivers may not notice this because of the communication difficulties. Previously, we conducted a study in which professional caregivers used heart rate (HR) monitoring to identify situations...
