The Impact of Catalyst Layer Composition and Structure on Performance and Durability of PEMWE Anodes

Advanced Materials Technologies, EarlyView.
This article explores a new type of anode for water electrolysis that uses less iridium, a rare and expensive metal. By combining stable iridium oxide with platinum and carbon‐based materials, the authors create a catalyst layer that maintains strong performance.

Six domesticated PiggyBac transposases together carry out programmed DNA elimination in Paramecium

eLife, 2018
The domestication of transposable elements has repeatedly occurred during evolution and domesticated transposases have often been implicated in programmed genome rearrangements, as remarkably illustrated in ciliates.

Recovery of platinum group metals from spent automotive catalysts: A review

Cleaner Engineering and Technology, 2021
In the last decades, a worldwide investment in the recovery or substitution of platinum group metals (PGMs) has been financed. PGMs have been classified as critical raw materials (CRMs), thus a circular economy model should be implemented for their ...

CellPolaris: Transfer Learning for Gene Regulatory Network Construction to Guide Cell State Transitions

Advanced Science, EarlyView.
CellPolaris decodes how transcription factors guide cell fate by building gene regulatory networks from transcriptomic data using transfer learning. It generates tissue‐ and cell‐type‐specific networks, identifies master regulators in cell state transitions, and simulates TF perturbations in developmental processes.

Comparison of Illumina MiSeq and the Ion Torrent PGM and S5 platforms for whole-genome sequencing of picornaviruses and caliciviruses

bioRxiv, 2019
Next-generation sequencing is a powerful tool for virological surveillance. While Illumina® and Ion Torrent® sequencing platforms are used extensively for generating viral RNA genome sequences, there is limited data comparing different platforms.

Noise Fingerprints as a Quantitative Order Parameter for Polarization‐ and Defect‐Mediated Switching in Hafnia Ferroelectrics

Advanced Science, EarlyView.
Low‐frequency noise fingerprints in hafnia ferroelectrics provide a quantitative handle to resolve the long‐standing debate between polarization‐mediated and defect‐mediated switching. By tuning oxygen vacancy density via ALD O3 dose time and applying a physically constrained deconvolution, we extract bias‐resolved current fractions for both mechanisms

A Catechol-Meter Based on Conventional Personal Glucose Meter for Portable Detection of Tyrosinase and Sodium Benzoate

Biosensors, 2022
In this study, the personal glucose meter (PGM) was first used as a fast and user-friendly meter for analyzing catechol (CA) based on the reduction of the mediator K3[Fe(CN)6] to K4[Fe(CN)6] in the glucose test strip.

PGM-Free ORR Catalysts Designed by Templating PANI-Type Polymers Containing Functional Groups with High Affinity to Iron

Journal of the Electrochemical Society, 2019
In this work, a coordination-chemistry approach was used to increase the content of nitrogen-coordinated iron moieties (Fe-N x ) in platinum group metal-free (PGM-free) catalysts for oxygen reduction reaction (ORR).
