Energy conversion in isothermal nonlinear irreversible processes - struggling for higher efficiency

open access: yes, 2017
First we discuss some early work of Ulrike Feudel on structure formation in nonlinear reactions including ions and the efficiency of the conversion of chemical into electrical energy.

The (Glg)ABCs of cyanobacteria: modelling of glycogen synthesis and functional divergence of glycogen synthases in Synechocystis sp. PCC 6803

open access: yesFEBS Letters, EarlyView.
We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

The Neglected Dimension of Well-Being: Analyzing the Development of "Conversion Efficiency" in Great Britain [PDF]

open access: yes
In Amartya Sen's capability approach, policy makers can focus on different levels to influence the well-being of a society. We argue that improving capability to function as well as absolute levels of functioning achievement should be complemented by ...

Structural biology of ferritin nanocages

open access: yesFEBS Letters, EarlyView.
Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...

Performance enhancement of nanogenerator achieved in branch-heterostructure piezoelectric ceramic fiber toward electrical transmission power line monitoring

open access: yesJournal of Advanced Ceramics
A flexible composite-based piezoelectric nanogenerator (PENG) with low cost, stable properties, and sensitivity to mechanical deformation is highly suitable for constructing self-powered sensing layers for distributed electrical transmission power lines.

Characterizing the salivary RNA landscape to identify potential diagnostic, prognostic, and follow‐up biomarkers for breast cancer

open access: yesMolecular Oncology, EarlyView.
This study explores salivary RNA for breast cancer (BC) diagnosis, prognosis, and follow‐up. High‐throughput RNA sequencing identified distinct salivary RNA signatures, including novel transcripts, that differentiate BC from healthy controls, characterize histological and molecular subtypes, and indicate lymph node involvement.

The role of nonlinear optical absorption in narrow-band difference frequency terahertz-wave generation

open access: yes, 2009
We present a general analysis of the influence of nonlinear optical absorption on terahertz generation via optical difference frequency generation, when reaching for the quantum conversion efficiency limit.

Bridging the gap: Multi‐stakeholder perspectives of molecular diagnostics in oncology

open access: yesMolecular Oncology, EarlyView.
Although molecular diagnostics is transforming cancer care, implementing novel technologies remains challenging. This study identifies unmet needs and technology requirements through a two‐step stakeholder involvement. Liquid biopsies for monitoring applications and predictive biomarker testing emerge as key unmet needs. Technology requirements vary by
