Photolabile coumarins with improved efficiency through azetidinyl substitution

Pablo Rivera Fuentes, Zacharias Thiel, Eric Vauthey

Azetidinyl substituents have been recently used to improve the fluorescence quantum yield of several classes of fluorophores. Herein, we demonstrate that other useful photochem. processes can be modulated using this strategy. In particular, we prepd. and m ...

Two-Dimensional Folding of Polypeptides into Molecular Nanostructures at Surfaces

Klaus Kern, Stephan Rauschenbach, Sabine Abb, Gordon Rinke

Herein we report the fabrication of molecular nanostructures on surfaces via two-dimensional (2D) folding of the nine amino acid peptide bradykinin. Soft-landing electrospray ion beam deposition in conjunction with high-resolution imaging by scanning tunne ...

Foldable Drones: from Biology to Technology

Dario Floreano, Stefano Mintchev, Jun Shintake

Current drones are developed with a fixed morphology that can limit their versatility and mission capabilities. There is biological evidence that adaptive morphological changes can not only extend dynamic performances, but also provide new functionalities. ...

Molecular Imaging of Biopolymers Enabled by Electrospray-Ion Beam Deposition

Sabine Abb

Biomolecular functional complexes often serve as inspiration for the development of artificial molecular nanostructures. The functionality of the biomolecular structures is based on complex and adaptable binding motifs that have evolved over billions of ye ...

Integrally attached timber folded surface structures

Andrea Stitic

In structural engineering, folded surface structures present one of the concepts for construction of self supporting column free systems. They utilize structural benefits of folding to achieve material saving and improve structural efficiency. The folding ...

Thermodynamic bounds on the ultra- and infra-affinity of Hsp70 for its substrates

Paolo De Los Rios, Basile Nguyen

The 70 kDa Heat Shock Proteins Hsp70 have several essential functions in living systems, such as protecting proteins against protein aggregation, assisting protein folding, remodeling protein complexes and driving the translocation into organelles. These f ...

A Low Profile Electromagnetic Actuator Design and Model for an Origami Parallel Platform

Jamie Paik, Amir Firouzeh, Marco Salerno

Thin foldable origami mechanisms allow reconfiguration of complex structures with large volumetric change, versatility, and at low cost; however, there is rarely a systematic way to make them autonomously actuated due to the lack of low profile actuators. ...

On the Analysis of Intrahost and Interhost Viral Populations: Human Cytomegalovirus as a Case Study of Pitfalls and Expectations

Jeffrey David Jensen, Sebastian Matuszewski, Susanne Petra Pfeifer

Intrahost and interhost assessments of viral diversity are often treated as measures of separate and distinct evolutionary processes, with numerous investigations reporting seemingly incompatible results between the two. For example, in human cytomegalovir ...

Properties of helium bubbles in covalent systems at the nanoscale: A combined numerical and experimental study

Cécile Hébert, Duncan Thomas Lindsay Alexander

The properties of nanometric-sized helium bubbles in silicon have been investigated using both spatially resolved electron-energy-loss spectroscopy combined with a recently developed method, and molecular-dynamics simulations. The experiments allowed for a ...

Magnetic microrobots with addressable shape control

Mahmut Selman Sakar

Shape shifting soft microrobots are generated from self-folding hydrogel bilayer structures. The folding conditions are analyzed to develop an optimal strategy for producing desired three-dimensional shapes. We present two different methods for programming ...
