Non-equilibrium stochastic dynamics of open ion channels [PDF]

, 2013
We present and discuss a modified version of reaction rate theory (RRT) to describe the passage of a positive ion through a biological ion channel. It takes explicit account of the non-equilibrium nature of the permeation process. Unlike traditional RRT,

Swelling‐Programmed Topographical Guidance for Dynamic Spheroid Self‐Assembly via a Mechanochemical Hydrogel Niche

Advanced Functional Materials, EarlyView.
A swelling‐programmed micropatterned hydrogel guides adherent cells through a controlled transition from cell–matrix anchoring to cadherin‐mediated cell–cell compaction, enabling rapid assembly of high‐viability spheroids with defined size and morphology.

Characterisation of electrospray properties in high vacuum with a view to application in colloid thruster technology

, 2005
PhDThe operational environment of colloid thrusters is high vacuum (10-3 _ 10-6 mbar) however, much of the experimental data collected to date to identify parameter relationships in cone jet mode electrosprays (ES), such as current-volumetric flow ...

Omnipolar Magnetic Field Detection by Superlattice‐Based Hall Sensor

Advanced Functional Materials, EarlyView.
Magnetic‐field‐induced electronic switching is demonstrated in unit‐cell‐engineered La0.7Sr0.3MnO3–BiFeO3 superlattices. Distinct substrate terminations modify magnetic and transport properties. Hall resistance measurements show omnipolar, hysteretic anomalous Hall switching above the Curie temperature, arising from Fe─Mn interfacial exchange, enabling

Toward Tunable Magnetic Dirac Semimetals: Mn Doping of Cd3As2

Advanced Functional Materials, EarlyView.
Dilute magnetic doping of topological semimetals offers a pathway to tune the topological phase via time reversal symmetry breaking. This is achieved by alloying the Dirac semimetal Cd3As2 with Mn via molecular beam epitaxy. Magnetotransport measurements provide preliminary evidence of changes to the electronic structure consistent with the emergence ...

Intrinsic Photoactive Star ZnPc–Poly(glutamate) Nanoplatforms for Multimodal Glioblastoma Therapy and Brain‐Targeted Delivery

Advanced Functional Materials, EarlyView.
An intrinsic photoactive star‐shaped zinc phtalocyanine‐poly(L‐glutamic acid) (ZnPc‐PGA) nanoplatform for multimodal glioblastoma (GBM) therapy and brain‐targeted elivery. A ZnPc‐PGA‐based multifunctional theranostic nanocarrier platform enables image‐guided, multimodal GBM therapy. ZnPc‐PGA nanocarriers support the integration of fluorescence imaging,

Electrostatic and non-electrostatic interactions of positively charged polypeptides with negatively charged lipid membranes

, 2008
Im Rahmen dieser Arbeit wurde die Wechselwirkung zwischen geladenen Peptiden und geladenen Membranen untersucht. Dazu wurde ein Modellsystem gewählt, das aus den zwei positiv geladenen Homopolypeptiden Poly(L-lysine) (PLL) und Poly(L-arginine) (PLA) besteht sowie aus negativ geladenen Membranen, die Phosphatidylglycerole (PG) oder Phosphatidsäuren (PA)
