The Global Polarity of Alcoholic Solvents and Water – Importance of the Collectively Acting Factors Density, Refractive Index and Hydrogen Bonding Forces
The DHBD quantity represents the hydroxyl group density of alcoholic solvents or water. DHBD is purely physically defined by the product of molar concentration of the solvent (N) and the factor Σn=n×f...
Publications | 07.11.2022Optical photothermal infrared spectroscopy with simultaneously acquired Raman spectroscopy for two-dimensional microplastic identification
In recent years, vibrational spectroscopic techniques based on Fourier transform infrared (FTIR) or Raman microspectroscopy have been suggested to fulfill the unmet need for microplastic particle detection...
Publications | 07.11.2022A full quantum mechanical approach assessing the chemical and electromagnetic effect in TERS
Tip-enhanced Raman spectroscopy (TERS) is a valuable method for surface analysis with nanometer to angstrom-scale resolution, however, the accurate simulation of particular TERS signals remains a computational...
Publications | 04.11.2022Immune mobilising T cell receptors redirect polyclonal CD8+ T cells in chronic HIV infection to form immunological synapses
T cell exhaustion develops in human immunodeficiency virus (HIV) infection due to chronic viral antigenic stimulation. This adaptive response primarily affects virus-specific CD8+ T cells, which may remain...
Publications | 04.11.2022Colorimetric Biosensors Based on Polymer/Gold Hybrid Nanoparticles: Topological Effects of the Polymer Coating
Gold nanoparticles decorated with analyte recognition units can form the basis of colorimetric (bio)sensors. The presentation of those recognition units may play a critical role in determining sensor sensitivity....
Publications | 21.10.2022Time-resolved velocity mapping at high magnetic fields: A preclinical comparison between stack-of-stars and cartesian 4D-Flow
Purpose: Prospectively-gated Cartesian 4D-flow (referred to as Cartesian-4Dflow) imaging suffers from long TE and intensified flow-related intravoxel-dephasing especially in preclinical ultra-high field...
Publications | 21.10.2022Multimodale spektroskopische Bildgebung: Ein neues leistungsstarkesWerkzeug fur die intraoperative Tumordiagnostik
Hintergrund: Die zunehmende Zahl an Krebserkrankungen erfordert neue bildgebende Ansätze fur eine intraoperative Tumorcharakterisierung. Fragestellung: Einsatz neuer optischer/photonischer Methoden mit...
Publications | 21.10.2022Locally Structured On-Chip Optofluidic Hollow-Core Light Cages for Single Nanoparticle Tracking
Nanoparticle tracking analysis (NTA) is a widely used methodology to investigate nanoscale systems at the single species level. Here, we introduce the locally structured on-chip optofluidic hollow-core...
Publications | 21.10.2022Review On Data-Centric Brain-Inspired Computing Paradigms Exploiting Emerging Memory Devices
Biologically-inspired neuromorphic computing paradigms are computational platforms that imitate synaptic and neuronal activities in the human brain to process big data flows in an efficient and cognitive...
Publications | 18.10.2022Bifacial dye membranes: ultrathin and free-standing although not being covalently bound
Layers of aligned dyes are key to photo-driven charge separation in dye sensitized solar cells, but cannot be exploited as rectifying membranes in photocatalysis to separate half-cells because they are...
