The topology of surface mediatrices

open access: yesTopology and its Applications, 2007
Given two points of a metric space the mediatrix is the set of all points which have the same distance from both points. In the paper under review the authors examine the topological structure of mediatrices in connected, compact 2-manifolds with respect to the metric induced from a Riemannian metric. Building on previous work [Topology Appl.

DNA‐Templated 2D Heterostructures as Phototriggered Dynamic Nanohybrids: From Releasing Molecular Loads to Controlling Enzyme Biocatalytic Function

open access: yesAdvanced Functional Materials, EarlyView.
DNA strands are employed both as dynamic linkers and nanoscale templates for the integration of Ag2S nanoparticles on MoS2, which in turn imparted photothermal responsiveness; this feature permits the selective cargo (fluorophore, quantum dots or an enzyme) release from the MoS2 surface in response to local heat induced by light irradiation.

Symbolic Block Decomposition In Hexahedral Mesh Generation

open access: yesComputer Science, 2005
Hexahedral mesh generation for three-dimensional solid objects is often done in stages. Usually an object is first subdivided into simple-shaped subregions, which then are filled withhexahedral finite elements. This article presents an automatic subdividing

Circular‐Polarization‐Sensitive Organic Photodetectors with a Chiral Nanopatterned Electrode Inverse‐Designed by Genetic Algorithm

open access: yesAdvanced Functional Materials, EarlyView.
A chiral photodetector capable of selectively distinguishing left‐ and right‐handed circularly polarized light is experimentally demonstrated. The device, which features a nanopatterned electrode inverse‐designed by a genetic algorithm within a metal–dielectric–metal nanocavity that incorporates a vacuum‐deposited small‐molecule multilayer, exhibits ...
