Interaction of Oligonucleotides with Gold Nanoparticles: Factors Beyond Electrostatic and Van‐Der Waals Forces

open access: yesAdvanced Materials Interfaces, EarlyView.
The formation of stable clusters of gold nanoparticles with oligonucleotides at different solution conditions is explored. DNA base homogeneity and strand directionality influence the binding with gold nanoparticles leading to interesting clustering behavior that can be relevant for SERS applications.

Deterministic Dynamics and Chaos: Epistemology and Interdisciplinary Methodology [PDF]

open access: yesInterdisciplinaria, Vol. 28, Nr. 2, pp. 279 - 298, 2012, 2011
We analyze, from a theoretical viewpoint, the bidirectional interdisciplinary relation between mathematics and psychology, focused on the mathematical theory of deterministic dynamical systems, and in particular, on the theory of chaos. On one hand, there is the direct classic relation: the application of mathematics to psychology.

Multi‐Scale Modeling of a 3D Soft Magnetoelectric Patch for Wireless Nerve Stimulation

open access: yesAdvanced Materials Interfaces, EarlyView.
Core‐shell, magnetoelectric nanoparticles (MENPs) can serve as wireless electric nano‐sources, thanks to their ability to generate high levels of electricity, when stimulated by a human‐safe external magnetic field. By combining MENPs with soft, biocompatible polymeric matrices and optimizing its composite configuration and electrical behavior via ...

Permanent Plasma Surface Functionalization of Internal Surface Areas

open access: yesAdvanced Materials Interfaces, EarlyView.
With applications in various fields including biomedical sciences, textiles, or filter industry, stable functionalization of porous membranes is indispensable. Plasma‐activated species with specific reactivities infiltrate porous substrates at different penetration depths due to their distinct energies and diffusivities.

A purely mathematical proof for the existence of the universe.

open access: yes, 2017
In this work, I present a minimalist approach to first-order logic and show how it implies an irrefutable equation which connects the field of formal logic to our major theories of physics. The method is sufficiently strong to recover General Relativity and the Dirac equation (and much more) from pure reason.The minimalist approach is, in many ways ...
