Atomic Force Microscopy (AFM)

Atomic Force Microscopy (AFM) 1. General Principle The Atomic Force Microscope is a kind of scanning probe microscope in which a topographical image of the sample surface can be achieved based on the interactions between a tip and a sample surface. The atomic force microscope was invented by Gerd Binning et al. in 1986 at IBM Zurich based on ...

1. Math 262 Exercises and Solutions (1) Let A be a 3 × 3 matrix with real entries. Prove that if A is not similar over R to a triangular matrix then A is similar over C to a diagonal matrix. Proof. Since A is a 3 × 3 matrix with real entries, the characteristic polynomial, f(x), of A is a polynomial of degree 3 with real coefficients. We know ...

Alcohol and Neurotransmitter Interactions

The main inhibitory neurotransmitter in the brain is gamma-aminobutyric acid (GABA). Acting through a recep-tor subtype called GABAA, GABA leads to a state of sedation and de-creased anxiety. Sedative medications such as the benzodiazepines (e.g., Valium®) also act at the GABAA receptor. Some reports suggest that short-term alcohol exposure ...
