Dataset associated with "Trifluoroacetic acid deposition from emissions of HFO-1234yf in India, China, and the Middle East"
We have investigated trifluoroacetic acid (TFA) formation from emissions of HFO-1234yf, its dry and wet deposition, and rainwater concentration over India, China, and the Middle East with GEOS-Chem and WRF-Chem models. We ... -
Quantum dot studies with time-resolved super-resolution microscopy
Quantum dots (QDs) are semiconductor nanoparticles whose optical properties make them ideal candidates for a myriad of applications including fluorescence imaging and light harvesting technologies. They are highly emissive ... -
Optically detected ion insertion dynamics in hexagonal tungsten oxide
Nanoparticle electrodes are attractive for electrochemical energy storage applications because their nanoscale dimensions decrease ion transport distances and generally increase ion insertion/extraction efficiency. However, ... -
Developing and investigating copper and iron chalcogenide nanoparticle syntheses to elucidate the underlying processes of formation
Nanoparticle technology is rapidly growing field due to the unique, tunable properties of nanoparticles (NPs) as compared to their bulk counterparts, enabling a wide range of new applications. The key step, however, to ... -
Molecular dynamics simulations of peptide and protein systems
Molecular systems composed of amino acids play an important role in biological systems and have numerous functions and applications due to their enormous chemical versatility. These systems are usually divided into peptides ... -

From colloidal solution to single particles: investigating energy flow from semiconductor nanocrystals to molecules
The interaction of nanomaterials and molecules is at the heart of many modern processes (catalysis, chemical synthesis, lighting, etc.). The presence of crystallographic defects in the nanomaterials can strongly influence ... -
Phosphorus ligand-coupling reactions for the functionalization of pyridine and other azines
Pyridines and related azines are ubiquitous in pharmaceuticals, agrochemicals, and materials. The discovery and development of new purpose-built molecules is contingent on our ability to modify these motifs. Described ... -
Developing paper-based devices for mapping agricultural pesticides and environmental contaminants
The detection of environmental contaminants is important to ensure the health of both humans and the environment. Currently, detection is done by instrumentation like liquid or gas chromatography coupled with mass spectrometry. ... -
Regioselective functionalization of pyridines and other azines
Pyridines and diazines serve as cores in pharmaceuticals and are common motifs in organomaterials and ligands. Selective functionalization of these motifs is of importance for discovery and optimization of new bioactive ... -
Study of structural organizations in amorphous oxide thin films for low mechanical loss mirror coatings in interferometric gravitational wave detectors, A
Amorphous thin films prepared from vapor deposition are nonequilibrium solids with structures dependent on their physical parameters, such as composition, and method of preparation. The macroscopic properties of an amorphous ... -
Fundamental research into gold nanocluster properties
Gold materials are popular for research into many applications with their interesting properties, such as magnetism, bio-inactivity, and other size-dependent properties. As the size of the gold material decreases from a ... -
Clonable selenium nanoparticle in action: high resolution localization of FtsZ using electron tomography, A
A meaningful understanding of biochemistry requires that we understand the function of proteins, which is heavily dependent on their structure and location within an organism. As the Resolution Revolution of cryo-electron ... -
Glyme-synthesized nanomaterials
Nanomaterials include materials with at least one dimension in the nanometer range. These materials include nanoparticles, quantum dots, thin films, self-assembled materials, supramolecular materials and more. Nanoscience ... -
Static and dynamic study of metal salt hydrates of weakly-coordinating fluoroanions by vibrational spectroscopy, gravimetry, and an analysis of previously published x-ray structures
Eighteen metal salt hydrates (Li(H2O)4(Al(OC(CF3)3)4), Li(H2O)(B(3,5-C6H3(CF3)2)4), Li(H2O)n(Ga(C2F5)4), Li(H2O)(PF6), Na(H2O)(PF6), Li2(H2O)4(B12F12), Na2(H2O)2(B12F12), K2(H2O)2(B12F12), Rb2(H2O)2(B12F12), Cs2(H2O)(B12F12), ... -
Using chemical ionization mass spectrometry to probe indoor and outdoor atmospheric chemistry
People spend the majority of their time in indoor environments. Knowledge of the sources, sinks, and chemistry of indoor pollutants is therefore imperative to indoor air quality and human health. We studied the indoor ... -
Determination of reliable minimum, disproof-based particle formation mechanisms: investigation of a second-generation Ir(0)n nanoparticle system
A long-sought goal in particle formation is an understanding of the chemical reaction mechanism. The complete understanding of the associated processes (nucleation, growth, and agglomeration) will yield particle size and ... -
Development of a multidisciplinary toolkit for the colloidal nanoparticle synthesis of copper selenophosphate, Cu3PSe4, a promising material for photovoltaics

Quantifying proximity, confinement, and interventions in disease outbreaks: a decision support framework for air-transported pathogens
The inability to communicate how infectious diseases are transmitted in human environments has triggered avoidance of interactions during the COVID-19 pandemic. We define a metric, Effective ReBreathed Volume (ERBV), that ... -
Effect of resins on the aggregation behavior of asphaltenes, The
Millions of barrels of crude oil are extracted on a daily basis. Crude oil has four main components separated by the SARA fractionation method.1 Asphaltenes are the heaviest component of the cured oil. They are known to ...
