- DRIFTS - Diffuse Reflectance Infrared Fourier Transform . . .
DRIFTS allows evaluation of non-transparent, highly absorbing materials to detect subtle changes on rough surfaces, designed to minimize reflection losses Understanding surface chemistry is crucial for catalyst innovation and determining modifications that will produce enhanced performance
- Single-Particle Motion in Given Electric and Magnetic Fields
Drift of the center of the circular orbit The drifts can be calculated one at a time and then added together Alternatively, they can be derived all together and show that the particle behaves like a composite entity that has both: Charge q, and Magnetic moment Average over one gyro-orbit is the gyrocenter Gyrating part is the gyroradius

A third adiabatic invariant can be associated with the periodic drift of a particle (due to rB and curvature drifts) around a dipole magnetic eld It is useful for studying particle motions in Earth's magnetosphere but is not addressed further here
- Introduction to FT-IR Sample Handling - Thermo Fisher Scientific
What types of samples can you analyze? DRIFTS is commonly used for the analysis of both organic and inorganic samples that can be ground into a fine powder (less than 10 microns) and mixed in a powder matrix such as potassium bromide (KBr) Typical sample types include: • Soft powders and powder mixtures • Hard polymers • Rigid polymers
- Understanding Thermal Drift - Epsilon Tech
When using load cells, extensometers, or other sensor systems, small variations in temperature over time typically produce a small offset in the reading which changes over time – thus it is called drift The relationship is often nonlinear and is related to the rate of change
- Diffuse Reflection Infrared Spectroscopy (Drifts . . .
The use of a diffuse reflection accessory and the associated DRIFTS (Diffuse Reflectance Infrared Fourier Transform Spec- troscopy) technique helps to circumvent these obstacles and to analyze materials under reactive atmosphere 1 THEORETICAL REVIEW: DIFFUSE REFLECTANCE INFRARED FOURIER TRANSFORM SPECTROSCOPY (DRIFTS) Any radiation focused on
- In-situ DRIFTS study of two-step CO2 capture and catalytic . . .
Two-step capture and methanation process was studied by DRIFTS over several materials by feeding a stream of 15% CO2 N2 for 1 h (i e , CO2 capture step) and followed by the reduction step with 20% H2 N2 for 1 h (i e , methanation step)
