Completing the Spectral Mosaic of Chloromethane by Adding the CHD₂Cl Missing Piece Through the Interplay of Rotational/Vibrational Spectroscopy and Quantum Chemical Calculations

Molecules
Chloromethane (CH3Cl) is a key chlorinated organic compound not only in atmospheric chemistry, but also in the field of molecular astrophysics and a possible biosignature in exoplanetary atmospheres.

Accurate Determination of Optical Constants of Amorphous Absorbing Thin Films by Spectroscopic Ellipsometry

, 2015
Spectroscopic ellipsometry (SE) and spectrophotometer are used to measure the ellipsometric parameters (psi and △) and transmittance of ultrathin diamond like carbon (DLC) film and amorphous silicon (a-Si) film respectively.

Multilayer Self‐Limiting Electrospray Deposition via Stepped Voltage Bias

Advanced Engineering Materials, EarlyView.
Self‐limiting electrospray deposition (SLED) uses a high voltage to generate and deposit a charged payload on a target surface. The coating retains its charge, repelling newly arriving material. SLED thickness can be decreased by applying a secondary bias to the target.

Spectroscopic constants from atomic properties: a machine learning approach [PDF]

We present a machine-learning approach toward predicting spectroscopic constants based on atomic properties. After collecting spectroscopic information on diatomics and generating an extensive database, we employ Gaussian process regression to identify ...

Superlubricity and Corrosion Inhibition Properties of Solvate Ionic Liquids in Hybrid Carbon Fiber Reinforced Plastic–Steel Interfaces

Advanced Engineering Materials, EarlyView.
Solvate ionic liquids lubrication reduced the coefficient of friction by ∼60% compared to dry sliding, reaching steady‐state values as low as 0.04–0.05. Corrosion weight‐loss measurements in 1 M HCl further demonstrated significant inhibition behavior, with only 100 ppm of [Li(G3)][TFSI] (∼68.5 μL/L) reducing corrosion‐product weight loss by 63 ...

Ab initio electronic structure and prospects for the formation of ultracold calcium–alkali-metal-atom molecular ions

New Journal of Physics, 2020
Experiments with cold ion–atom mixtures have recently opened the way for the production and application of ultracold molecular ions. Here, in a comparative study, we theoretically investigate ground and several excited electronic states and prospects for

The Schumann-Runge absorption bands of 16O 18O in the wavelength region 175-205 nm and spectroscopic constants of isotopic oxygen molecules

, 1989
High-resolution absorption spectra of 16O 18O have been photographed, at 300 and 78 K, throughout the region 175-205 nm, in the first order of a 2400 lines/mm grating in a 6.65-m vacuum spectrograph at a dispersion of 0.06 nm/mm.

Self‐Cleaning Sensor Surfaces for Long‐Term Environmental Monitoring

Advanced Engineering Materials, EarlyView.
Long‐term use of unattended outdoor sensors without soiling or biofouling is achieved through generation of a micro‐ and nanorough cuvette surface by combing hydrophobic nanoparticles with fluorinated polymers, crosslinked and surface‐attached through CHic chemistry. The coating demonstrates self‐cleaning behavior and prolonged outdoor stability, which

Reaction Pathway and Rovibrational Analysis of Aluminum Nitride Species as Potential Dust Grain Nucleation Agents

The Astrophysical Journal
A dust nucleating agent may be present in interstellar or circumstellar media that has gone seemingly undetected and unstudied for decades. Some analyses of the Murchison CM2 meteorite suggest that at least some of the aluminum present within condensed ...
