Above: The molecular tool and general mechanosynthetic processes. (A) Overview of the probe and sample (above and below, respectively, not to scale) for IM-STM enabled mechanosynthesis. (B) Zoomed-in focus on the desired surface binding of the EAOGe–C2I molecular tool. (C) Chemical scheme for (B). (D) The deiodinated tool (EAOGe–C2●). Approaching the tool to the probe … Continue reading "Towards…
Above: NASA’s James Webb Space Telescope recently imaged the Sombrero Galaxy with its MIRI (Mid-Infrared Instrument), resolving the clumpy nature of the dust along the galaxy’s outer ring. The mid-infrared light highlights the gas and dust that are part of star formation taking place within the Sombrero Galaxy’s outer disk. The rings of the Sombrero Galaxy … Continue reading "Free Astronomy…
Above: The most-stable gas-phase configuration (1a, two views shown) exhibits π···H THF interactions (shown in gold) and F···H interactions (shown in green). The next most stable configurations (1c, shown as representative) exhibit a significant π···π interaction (shown in purple) and F···H interactions. In the higher energy configurations most similar to the crystal structure (crystal), there ……
Above: Examples of subtractive and additive mechanosynthesis under IM-STM/UHV conditions. HAT between activated 19 (chemisorbed on a Si(100)-2×1 surface) and H:Si(100)-2×1 SPC apex (A) and possible reaction outcomes between activated 19 (chemisorbed on a Si(100)-2×1 surface) and Si(100)-2×1 SPC apex including additive (C2-transfer) and subtractive (Si-atom abstraction) mechanosynthesis (B). BDEs…
Above: Mechanosynthetic C2 donation. (A) Schematic of the inverted-mode STM setup. EAOGe-C2I molecules are deposited on flat Si(100), and an H-passivated Si(100) silicon probe chip (SPC) with a flat, crystalline apex is positioned above the surface. The molecules function both as imaging probes, where an applied bias (VS) drives a tunneling current (IT) through the … Continue reading "Atomically…

Above: The current header for the www.rochesterastronomy.org website. Subject to change (when the template finally breaks). From the shameless self-promotion department (isn't that the whole site?) – I was honored to have been selected as the Outstanding Astronomer of 2025 by my current home astronomy club, the Astronomy Section of the Rochester Academy of Science … Continue reading "Looking Down…
Above: An artistic rendering of a dust and gas disk encircling the young exoplanet CT Cha b, 625 light-years from Earth. Spectroscopic data from NASA’s James Webb Space Telescope suggests the disk contains the raw materials for moon formation: diacetylene, hydrogen cyanide, propyne, acetylene, ethane, carbon dioxide, and benzene. The planet appears at lower right, … Continue reading "Free…
