Rethinking plastic waste: innovations in enzymatic breakdown of oil‐based polyesters and bioplastics

FEBS Open Bio, EarlyView.
Plastic pollution remains a critical environmental challenge, and current mechanical and chemical recycling methods are insufficient to achieve a fully circular economy. This review highlights recent breakthroughs in the enzymatic depolymerization of both oil‐derived polyesters and bioplastics, including high‐throughput protein engineering, de novo ...

Raman‐based label‐free microscopic analysis of the pancreas in living zebrafish larvae

FEBS Open Bio, EarlyView.
Forward stimulated Raman scattering (F‐SRS) and epi coherent anti‐Stokes Raman scattering (E‐CARS) allow label‐free discrimination of distinct subcellular structures in the pancreas of living zebrafish larvae. Given the straightforward applicability, we anticipate broad implementation of Raman microscopy in other organs and across various biomedical ...

SIRT4 positively regulates autophagy via ULK1, but independently of HDAC6 and OPA1

FEBS Open Bio, EarlyView.
Cells expressing SIRT4 (H161Y), a catalytically inactive mutant of the sirtuin SIRT4, fail to upregulate LC3B‐II and exhibit a reduced autophagic flux under stress conditions. Interestingly, SIRT4(H161Y) promotes phosphorylation of ULK1 at S638 and S758 that are associated with inhibition of autophagy initiation.

A New Feed-Forward Control for Dynamics Improvement in a Dual-Input DC–DC Converter for Hybrid Vehicle Applications

Energies
In this study, a double-input single-output bidirectional DC–DC converter is considered. This particular architecture allows less switches to be used than a conventional solution.

A New Hard Switching Bidirectional Converter With High Power Density [PDF]

Journal of Intelligent Procedures in Electrical Technology, 2010
In this paper, a new isolated dc-dc bidirectional converter is proposed. This converter consists of two transformers (flyback and forward) and only one switch in primary side and one switch in secondary side of transformers.

Contribution of particulate nitrate to airborne measurements of total reactive nitrogen [PDF]

, 2005
Simultaneous measurements of speciated, total reactive nitrogen (NOy) and particulate NO3 (particle diameter <1.3 μm) were made on board the NASA P-3B aircraft over the western Pacific in February-April 2001 during the Transport and Chemical Evolution

Dual‐passive snubber dual‐switch forward converter

Electronics Letters, 2017
A dual‐passive snubber (DPS) for dual‐switch forward converter is presented. Snubber networks provide zero‐current turn‐on and zero‐voltage turn‐off conditions for dual switches. DPS achieves soft switching conditions for power diodes at secondary side of transformer.

dUTPase is essential in zebrafish development and possesses several single‐nucleotide variants with pronounced structural and functional consequences

FEBS Open Bio, EarlyView.
dUTPases are involved in balancing the appropriate nucleotide pools. We showed that dUTPase is essential for normal development in zebrafish. The different zebrafish genomes contain several single‐nucleotide variations (SNPs) of the dut gene. One of the dUTPase variants displayed drastically lower protein stability and catalytic efficiency as compared ...

Zero‐current transition single‐ended forward converter [PDF]

IET Power Electronics, 2020
In this study, a novel zero‐current transition (ZCT) auxiliary circuit is applied to pulse‐width modulation single‐ended forward converter (PWM SEFC). The proposed ZCT circuit has achieved the power switch zero‐current switching (ZCS) turn‐on; the power switch ZCT turn‐off; the auxiliary switch ZCS and zero‐voltage switching turn on/off and soft ...
