Ultra‐Sensitive Nanofiber‐Based Triboelectric Nanogenerator for Energy Harvesting and Self‐Powered Sensing

open access: yesAdvanced Materials, EarlyView.
A multidimensional molecular strategy optimizes the tribonegative layer by electrospinning PVDF‐HFP for dipole alignment and crystallinity, followed by 2D borophene doping to enhance conductivity and charge trapping. Integrated with Nylon‐66 nanofibers, the composite device delivers a record sensitivity of 53.8 ± 1.2 V kPa−1 at 3 Hz, enabling ultra ...

Chemomechanical Origin of Morphological Disparity in Lithium Metal Electrodeposition

open access: yesAdvanced Materials, EarlyView.
Selective dissociation of either solvent or salt on copper current collector induced different solid electrolyte interphase (SEI) layers. The solvent derived organic SEI favors formation of Li whisker, while salt derived SEI favors formation of Li particle, revealing the root cause of Li morphology disparity within the same cell.

Systematic Evaluation of Isolation Techniques and Freeze‐Thaw Effects on Plasma Extracellular Vesicle Heterogeneity and Subpopulation Profiling

open access: yesJournal of Extracellular Biology
Extracellular vesicles (EVs) are increasingly recognized as promising disease biomarkers and therapeutic carriers. However, standardizing blood‐derived EV isolation remains challenging due to the heterogeneity of EV populations and variability among ...

Efficient algorithms for Asymmetric Flow Field Flow Fractionation

open access: yes, 2014
This thesis is devoted to the modeling and simulation of Asymmetric Flow Field Flow Fractionation, which is a technique for separating particles of submicron scale. This process is a part of large family of Field Flow Fractionation techniques and has a very broad range of industrial applications, e. g.

Monte Carlo simulation of asymmetric flow field flow fractionation

open access: yes, 2019
SDEs are used in the description of a variety of industrial processes. While numerous studies on Monte Carlo and multilevel Monte Carlo methods for SDEs used in financial engineering (option pricing, calculation of Greeks etc.) are available in the literature, technical applications are not so broadly studied.

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 ...
