Electron beam co-deposited Bi1xTex
Bi1_xTex-compounds are among the most commonly used thermoelectric materials due to their high Seebeck coefficient, high electrical conductivity and low thermal conductivity at room temperature. N-type...
PublicationsComplex-valued Chemometrics in Spectroscopy: Principal Component Regression
We have begun introducing complex-valued principal component regression (PCR) into spectroscopy. Unlike traditional methods that are constrained to either the real or imaginary axis, this approach allows...
PublicationsTime-deterministic cryo-optical microscopy
Fluorescence microscopy enables the visualization of cellular morphology, molecular distribution, ion distribution, and their dynamic behaviors during biological processes. Enhancing the signal-to-noise...
PublicationsCrystalline Texture of Gold nanoparticles formed on polished silicon using solid state and laser-induced dewetting
We aim to demonstrate the gold nanoparticle formation on silicon substrates by a time-consuming furnace process and a ns-short laser-induced process as methods that can be performed under ambient conditions....
PublicationsDeviations from the Beer-Lambert approximation investigated by 2D-Correlation IR spectroscopy
Two-dimensional correlation spectroscopy (2D-COS) is a highly sensitive technique for detecting deviations from the Beer–Lambert approximation through asynchronous spectra. In this study, we apply 2D-COS...
PublicationsInducing Hard Carbon-like Sodium Storage Behavior in Graphitizable Carbon via PostSynthetic Introduction of Closed Porosity
Hard carbon is commonly used as negative electrode in sodium-ion-batteries (SIBs). Another type of disordered carbon, soft car-bon (SC, also known as graphitizable carbon), is considered as unsuitable...
PublicationsThree-dimensional inversion of QAMT airborne natural-source electromagnetic data
Airborne natural-source electromagnetics (EM), similar to the magnetovariational technique, offers the potential of great penetration depth combined with superior time- and cost-efficiency compared with...
PublicationsLabel-free differentiation of antimicrobial resistance groups using Raman spectroscopy
Increasing antimicrobial resistance (AMR) has developed into an enormous health burden. Here, a systematic investigation was conducted to evaluate the discriminative performance of Raman spectroscopy between...
PublicationsPeculiarities in thermal transport of nanostructured silicon arrays with different morphology
This study explores the thermal conductivity of nanostructured porous silicon with different morphology produced by metal-assisted chemical etching of silicon wafers with different dopants, doping levels...
PublicationsOn-chip twisted hollow-core light cages: enhancing planar photonics with 3D nanoprinting
Twisted optical fibers are a promising platform for manipulating circularly polarized light and orbital angular momentum beams for applications such as nonlinear frequency conversion, optical communication,...
