Temperature programmed desorption (TPD) is the method of observing desorbed molecules from a surface when the surface temperature is increased. When experiments are performed using well-defined surfaces of single-crystalline samples in a continuously pumped ultra-high vacuum (UHV) chamber, then this experimental technique is often also referred to as thermal desorption spectroscopy or thermal ...
There were 32 positions for possible hole locations, giving approximately 4.3 billion different keys. The key could easily be changed for each new guest by inserting a new key template in the lock that matched the new key. [2] In the early 1980s, the key card lock was electrified with LEDs that detected the holes. A keycard with a magnetic stripe

There’s no shame in asking for Wordle assistance now and again. Before diving into the hints and solutions for the Thursday, Feb. 6 puzzle, though, let’s go over the basics of Wordle.
The 3DO Blaster is an add-on produced by Creative Labs from 1994 designed to allow compatible Windows-based PCs to play 3DO format games. It is a full-sized ISA compatibility card with the 3DO logic board included, with the input (controllers) and output (video & audio) redirected to the PC.
Typical pulse as measured with THz-TDS. In physics, terahertz time-domain spectroscopy (THz-TDS) is a spectroscopic technique in which the properties of matter are probed with short pulses of terahertz radiation. The generation and detection scheme is sensitive to the sample's effect on both the amplitude and the phase of the terahertz radiation.
Barclays strategists estimate that the tariffs could lead to a 2.8% drag on S&P 500 company earnings, including the projected fallout from retaliatory measures from the targeted countries.
Demonstrators gather near the U.S. Capitol on Presidents' Day to protest against U.S. President Donald Trump's actions during his first weeks in office, in Washington, D.C., U.S., February 17, 2025.
