Quantum chemical calculations have proven to be a reliable tool for the prediction of thermodynamics quantities, particularly for smaller organic species
The major cause of deteriorating concrete in the infrastructure is corrosion of the reinforcing steel. This is also the major mechanism of deterioration of
Time-of-flight secondary ion mass spectrometry (ToF-SIMS) employs a pulsed primary ion beam and a time-of-flight mass analyzer for the detection of molecular
The following videos and corresponding narrated PowerPoint presentations are provided for training and education in chemical metrology. Each presentation
Ultra-dense networks will arise not only from an expanded user base and shorter links, but also from an enriched topology, including different technologies and
Theory and simulation are used to advance our understanding of pure and multicomponent fluids confined in tight spaces, such as the pores of a zeolite, metal
Much of our knowledge of protein folding comes from experiments on polypeptides in dilute solutions or from theoretical models of isolated proteins. However
Protein drugs are the fastest-growing class of drugs in the pharmaceutical industry. However, they can be plagued by long-term stability issues, including
We develop and deploy portable vapor sampling instruments to collect detailed chemical information in the field, in sampling situations where the laboratory is
We develop and evaluate dynamic headspace sampling methods to capture and concentrate vapors from single components (solid or liquid) to determine vapor
Compared with conventional, physical measurements, the cost of computational modeling continues to drop. This has driven many industries to incorporate
