Self-perfection by liquefaction (SPEL) was used to fabricate nanoimprint molds with an array of sub-25 nm diameter pillars (200 nm period), resulting in nearly perfect cylindrical shape and smooth sidewalls. SPEL turned an array of irregularly shaped Cr polygons into an array of nearly perfect circular dots with small diameter. The Cr dot arrays were then transferred to SiO(2) or Si pillar arra...

Earlier this year, European authorities agreed on the second pillar of the banking union, a single resolution mechanism, to come into effect in 2016. After the ECB taking over responsibility for bank supervision (directly for the largest, indirectly for all banks) in the Eurozone, centralizing resolution as complement for centralized supervision has been an important next step. The result is a ...

Microand nano-hierarchical structures (lamellae, setae, branches, and spatulae) on the toe pads of many animals play key roles for generating strong but reversible adhesion for locomotion. The hierarchical structure possesses significantly reduced, effective elastic modulus (Eeff), as compared to the inherent elastic modulus (Einh) of the corresponding biological material (and therefore contrib...

This paper reports a gradient elution system for pressure-driven liquid chromatography (LC) on a chip. We have already reported the microfabrication of efficient pillar array columns with low dispersion turns. For faster and more efficient analysis, we fabricated a gradient elution system with a cross-Tesla mixer for the effective mixing of two solutions on a chip with a separation channel of p...

A water-soluble linear supramolecular polymer was efficiently constructed driven by pillar[5]arene-based host-guest molecular recognition.

Both Skow (2007) and Callender (2008) independently argue that time can be distinguished from space due to the special role it plays in our laws of nature: our laws determine the behaviour of physical systems across time, but not across space. In this work we asses the claim that the laws of nature might provide the basis for distinguishing time from space by looking specifically at the claims ...

The work presented herein evaluates silicon nano-pillar arrays for use in planar chromatography. Electron beam lithography and metal thermal dewetting protocols were used to create nano-thin layer chromatography platforms. With these fabrication methods we are able to reduce the size of the characteristic features in a separation medium below that used in ultra-thin layer chromatography; i.e. p...
