Investigation of the laser fluence and wavelength dependence in surface‐assisted laser desorption/ionization mass spectrometry using gold nanoparticles

open access: yesRapid Communications in Mass Spectrometry, EarlyView.
Rationale Surface‐assisted laser desorption/ionization (SALDI) mass spectrometry (MS) builds on the use of nanostructured surfaces (e.g., coatings of colloidal nanoparticles) to promote analyte desorption and ionization. The SALDI process is believed to occur mainly through thermal processes, resulting from heating of the nanosubstrate upon absorption ...

Why Autonomous Vehicles Are Not Ready Yet: A Multi‐Disciplinary Review of Problems, Attempted Solutions, and Future Directions

open access: yesJournal of Field Robotics, EarlyView.
ABSTRACT Personal autonomous vehicles can sense their surrounding environment, plan their route, and drive with little or no involvement of human drivers. Despite the latest technological advancements and the hopeful announcements made by leading entrepreneurs, to date no personal vehicle is approved for road circulation in a “fully” or “semi ...

X‐Ray Photoelectron Spectroscopy Study of Ni and Ni–SiO2 Coatings Electrodeposited From Deep Eutectic Solvent

open access: yesSurface and Interface Analysis, EarlyView.
ABSTRACT Ni and nanocomposite Ni–SiO2 coatings with nanostructured Ni crystalline characteristics were electrodeposited at 8 mA cm−2 from an environmentally friendly deep eutectic solvent (DES)–based electrolyte containing 0 and 30 g/L of SiO2 nanoparticles. X‐ray photoelectron spectroscopy study was performed on the coatings to study the effect of the

Exploratory XPS Evidence for Ca–N Environments at the Organic–Mineral Interface in Bone

open access: yesSurface and Interface Analysis, EarlyView.
ABSTRACT Bone derives its remarkable mechanical properties from the nanoscale relationship between its organic matrix and mineral components. While interfacial interactions are known to affect bone mechanics, direct evidence of chemical bonding at this interface has been lacking.

Roughness Measurements at Small and Uneven Surfaces of Ceramic Foam Filters

open access: yesSurface and Interface Analysis, EarlyView.
ABSTRACT This study investigated the possibility of roughness characterization of ceramic foam filters using a laser scanning microscope, examining the influence of magnification, measured area, cutoff wavelength (λc), measured roughness parameter, and position within the ceramic foam on the measured roughness data. Firstly, the effect of magnification
