Bioxolography Using Diphenyliodonium Chloride and N‐Vinylpyrrolidone Enables Rapid High‐Resolution Volumetric 3D Printing of Spatially Encoded Living Matter

open access: yesAdvanced Materials, EarlyView.
Bioxolography, a novel volumetric 3D‐bioprinting technique, enables rapid and high‐resolution fabrication of >1 cm3 engineered living materials. A newly developed three‐component photoinitiator system significantly enhances the photoreactivity of gelatin methacryloyl‐based bioresins, allowing for precise xolographic bioprinting.

On‐Chip Active Non‐Reciprocal Topological Photonics

open access: yesAdvanced Materials, EarlyView.
An ultra‐compact and efficient on‐chip isolator is experimentally demonstrated by integrating magneto‐optical InSb onto a terahertz silicon topological chip. The simultaneous breaking of spatial and temporal reversal symmetries forms a valley‐conserved non‐reciprocal waveguide mode, enabling a compact cavity size of 6.4 × 2.5λ2 and a low insertion loss

PERMANENT AND DOMINANT OF MATRIX OVER INTERVAL MIN-PLUS ALGEBRA

open access: yesBarekeng
A min-plus algebra is a set , where is the set of all real numbers equipped with two binary operations, namely minimum and addition . Every square matrix in min-plus algebra can always be calculated as a permanent and dominant matrix.

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.

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 ...
