Smart Dust for Chemical Mapping

open access: yesAdvanced Materials, EarlyView.
This review article explores the advancement of smart dust networks for high‐resolution spatial and temporal chemical mapping. Comprising miniature, wireless sensors, and communication devices, smart dust autonomously collects, processes, and transmits data via swarm‐based communication.

Comment on "Nonreciprocal Light Propagation in a Silicon Photonic Circuit" in Science 333, 729-733 (2011) [PDF]

open access: yesarXiv, 2011
In the recent article by Feng et al. [Science 333, 729-733 (2011)] a system is proposed with a periodic spatial modulation of refractive index and absorption. It is claimed that this system is nonreciprocal and can be used as an optical isolator.

A note on -hyponormal operators

open access: yesJournal of Inequalities and Applications, 2002
Let be a -hyponormal operator with the polar decomposition . In this paper, we show the following: (1) If is normal, then is normal. (2) If , then is also -hyponormal. (3) There exists a -hyponormal operator such that and .

Flexographic Printed Flexible Thermochromic Stickers for Smart Sensing Applications

open access: yesAdvanced Materials Interfaces, EarlyView.
Thermochromic complexes of 1‐butyl‐3‐methylimidazolium chloride and 4‐chloronickelate are synthesized and incorporated in hydroxypropyl cellulose‐based water inks. Films with 40 wt.% thermochromic complexes and three layers are flexographic printed on polypropylene tags in a process compatible with roll‐to‐roll manufacturing. After encapsulation with a

Constant Enzymatic in situ Production of H2O2 for an Unspecific Peroxygenase by an l–Amino Acid Oxidase

open access: yesAdvanced Synthesis &Catalysis, EarlyView.
Abstract Unspecific Peroxygenases have been the subject of a lot of research in the recent past as they offer opportunities for green hydroxylation reactions using hydrogen peroxide (H2O2) as donor. A striking problem of UPOs is their low stability against their own co‐substrate H2O2. In order to prevent the deactivation, we developed an enzyme cascade

circRNAome Profiling in Oral Carcinoma Unveils a Novel circFLNB that Mediates Tumour Growth-Regulating Transcriptional Response

open access: yesCells, 2020
Deep sequencing technologies have revealed the once uncharted non-coding transcriptome of circular RNAs (circRNAs). Despite the lack of protein-coding potential, these unorthodox yet highly stable RNA species are known to act as critical gene regulatory ...

The Global Warming Potential of Geoengineering via Radiative Cooling

open access: yesAdvanced Sustainable Systems, EarlyView.
The cooling power of engineered radiative cooling materials is determined and compared to conventional construction and roofing materials and Earth's natural surfaces. Results show if 1% of Earth's surface are to be covered with state‐of‐the‐art radiative cooling materials the terrestrial radiative forcing would decrease by 1.61 W·m−2 (from 0.6 to −1 ...
