Machine Learning‐Supported Analysis for Predicting and Visualizing Nonlinear Relationships Between Material Properties in Electroplated Chromium Layers

Advanced Engineering Materials, EarlyView.
This study applies machine learning regression to predict chromium layer thickness in decorative trivalent chromium electroplating, using 441 experiments from laboratory‐scale (1L) and pilot‐scale (14L) setups. Tree‐based models, particularly CatBoost, outperformed linear regression by capturing nonlinear parameter interactions (R2$R^2$ up to 0.77 ...

Determination of Carbon in Aerosol by X-Ray Fluorescence Spectrometry

Analytical Sciences, 1988
Carbon concentration in aerosol samples was determined by X-ray fluorescence spectrometry using a synthetic multilayers crystal (W/C, 2d=16.0nm) as an analyzer. X-Ray fluorescence is an excellent method because of its handiness and non-destructive nature as well as the simultaneous determination of a number of elements with low and high atomic numbers ...

A Practical Noise2Noise Denoising Pipeline for High‐Throughput Raman Spectroscopy

Advanced Engineering Materials, EarlyView.
A lightweight and reproducible denoising pipeline for high‐throughput Raman spectroscopy is introduced, based on a 1D convolutional autoencoder trained with a Noise2Noise strategy. Using only repeated short‐exposure acquisitions, the method suppresses stochastic noise without reference spectra, enabling reliable spectral reconstruction while preserving

Investigating the Effect of Inclination Angle and the Influence of Scan Parameters on the Appearance and Thermal and Mechanical Properties of Filigree Tension Rods of LPBF‐Manufactured NiTi Shape‐Memory Alloys

Advanced Engineering Materials, EarlyView.
This article investigates the dependence of the properties on the manufacturing orientation in the form of the inclination angle to the build plate of LPBF‐fabricated NiTi rods with a diameter of 150–220 µm. Metallographic, chemical, thermal, and mechanical characterization show behavior under identical manufacturing conditions that ranges from ...

Metal and Complementary Molecular Bioimaging in Alzheimer’s Disease

Frontiers in Aging Neuroscience, 2014
Alzheimer’s disease (AD) is the leading cause of dementia in the elderly. AD represents a complex neurological disorder which is best understood as the consequence of a number of interconnected genetic and lifestyle variables, which culminate in multiple

DNA‐Templated 2D Heterostructures as Phototriggered Dynamic Nanohybrids: From Releasing Molecular Loads to Controlling Enzyme Biocatalytic Function

Advanced Functional Materials, EarlyView.
DNA strands are employed both as dynamic linkers and nanoscale templates for the integration of Ag2S nanoparticles on MoS2, which in turn imparted photothermal responsiveness; this feature permits the selective cargo (fluorophore, quantum dots or an enzyme) release from the MoS2 surface in response to local heat induced by light irradiation.

Improvement of 93mNb and 103mRh activity measurement methodology for reactor dosimetry

EPJ Web of Conferences, 2017
Reactor dosimetry is based on the analysis of the activity of irradiated dosimeters, such as 93mNb and 103mRh. The activity measurement of these dosimeters is conventionally performed by X-ray spectrometry, but the low-energy of emitted photons makes it ...

Calculation of Fluorescence Intensities in Grazing-Emission X-Ray Fluorescence Spectrometry

Analytical Sciences, 1995
The fluorescence intensities in grazing-emission X-ray fluorescence spectrometry were calculated by applying asymptotics to the Fourier integrals resulting from the Helmholtz equation. This approach has led to a straightforward interpretation of the interference of fluorescence radiation from layered materials.
