Save as: TIFF black/white bitmap with a resolution of 720 dpi (small molecules) to 240 dpi (large molecules) (in ChemDraw under the Options button in the Save as TIFF dialog). ChemDraw / ChemBioDraw 11 (2007) cannot save black and white TIFF images. Therefore, save as a 1200 dpi greyscale TIFF image and decrease the color depth to 2 bit (black ...
ACD/ChemSketch allows for both basic structure drawing and importation of 3D and 2D .MDL files from other molecular modelling programs. ChemSketch has been favorably compared to other molecular modelling software, especially ChemDraw, based on its ability to display a wide range of structural components and the ease of creating complex structures quickly.
A Newman projection is a drawing that helps visualize the 3-dimensional structure of a molecule. [1] This projection most commonly sights down a carbon-carbon bond, making it a very useful way to visualize the stereochemistry of alkanes.
ChemDraw is a molecule editor first developed in 1985 by Selena "Sally" Evans, her husband David A. Evans, and Stewart Rubenstein [1] [2] (later by the cheminformatics company CambridgeSoft). The company was sold to PerkinElmer in 2011. [ 3 ]
ChemWindow is a chemical structure drawing molecule editor and publishing program now published by John Wiley & Sons as of 2020, [1] originally developed by Bio-Rad Laboratories, Inc. [2] [3] It was first developed by SoftShell International in the 1990s. [4]
This area of organometallic chemistry was first developed in the 1950s. Bent metallocenes are represented by compounds of the type [MCp 2 L x]. Some are catalysts for ethylene polymerization. [3] Metallocenes are often thermally stable, and find use as catalysts in various types of reactions.
This coconut wax candle from Volupsa has notes of lemon, thyme, blackberry and amber. Pro tip: This is also a sure hit at a White Elephant or Secret Santa party. $26 at Nordstrom.
David A. Evans (January 11, 1941 – April 29, 2022) [1] [2] [3] was an American chemist who was the Abbott and James Lawrence professor of chemistry at Harvard University. [4] [5] He was a prominent figure in the field of organic chemistry and his research focused on synthetic chemistry and total synthesis, particularly of large biologically active molecules.
