Piezoelectric Stimulation of Neural Cells: Exploring the Synergistic Potential of Hybrid Scaffolds for Enhanced Regeneration

open access: yesAdvanced Materials Interfaces, EarlyView.
Hybrid piezoelectric scaffolds offer a promising route for Central Nervous System regeneration by combining structural and electrical cues to support neural stem cell growth. This review highlights their potential to overcome current challenges in neural tissue engineering by exploring porous hybrid materials, their biological interactions, and ...

Permittering og sykefravær

open access: yes, 2004
Målet med denne rapporten var å finne ut om det er noen samvariasjon mellom sykefravær og permittering. Bakgrunnen er at lønnstakere har et ikke ubetydelig inntektsbortfall ved en permittering, noe som gir et økonomisk incitament til å bli sykemeldt i stedet.

Membrane Semi‐Permeability and Ion Selectivity in Chemiosmosis: Open Systems Volume Dependence of Electrolyte Chemistry

open access: yesAdvanced Materials Interfaces, EarlyView.
Very small cellular compartments can break electroneutrality and harness proton gradients without active transport structures, whereas larger volumes cannot, underscoring why life's critical energy processes are confined in microscopic spaces. ABSTRACT The effect of pH changes in external ionic solutions on liposomes entrapping non‐permeable weak acid ...

Charge Injection for Polarization Screening at Electrode Interfaces and the Antiferroelectric Double Hysteresis Loop of La‐Doped Pb(Zr,Sn,Ti)O3

open access: yesAdvanced Materials Interfaces, EarlyView.
Screening of the bound polarization charges of ferroelectrics at electrode interfaces is accommodated either by electrode charges or by charge injection. By means of X‐ray photoelectron spectroscopy with in‐situ polarization reversal, it is demonstrated that screening charges at antiferroelectric La‐doped Pb(Zr,Ti)O3 are injected, while they remain at ...

Combinatorial Screening for Europium Induced Defect Engineering in Titania Anodic Memristors

open access: yesAdvanced Materials Interfaces, EarlyView.
A Ti‐Eu thin‐film combinatorial libary (3‐17 at.% Eu) was fabricated by co‐sputtering and anodisation. Systematic screening revealed forming‐free memristors with analog switching, with compositions between 7‐17 at.% Eu showing improved endurance and multilevel resistive states.
