A Web Tool for Calculating Substituent Denoscriptors Compatible with Hammett Sigma Constants

The electron-donating and -accepting power of organic substituents is an important parameter affecting many properties of parent molecules, most notably their reactivity and pKa of ionisable groups. These substituent properties are described by Hammett σ constants obtained by measuring ionization constants of substituted benzoic acids. Although values of the Hammett σ constants have been measured for the most common functional groups, data for many important substituents are not available. In the present study, a method to calculate substituent denoscriptors compatible with the Hammett σ constants using quantum-chemically derived parameters is described. On this basis, a free web tool allowing to calculate electronic and hydrophobic substituent denoscriptors is made available at the link below:

Orbital Optimized Density Functional Theory for Electronic Excited States
—-
Is this a revolution for theoretical excited-state chemistry?

https://pubs.acs.org/doi/10.1021/acs.jpclett.1c00744
To publish in academia is hard (and there is bias involved to make it harder)
—-
In a new study, the same paper as subjected to 534 reviewers. The name of the main author was changed to a novice scientist or to a high level (Nobel laureate) scientist. Depending just on the author’s name THE SAME paper was well reviewed (if the author is famous) or rejected if the author is not famous.

OPEN ACCESS
Best-Practice DFT Protocols for Basic Molecular Computational Chemistry

Many chemical investigations are supported by routine calculations of molecular structures, reaction energies, barrier heights, and spectroscopic properties. Most of these quantum-chemical calculations apply various combinations of DFT-based methods. This Scientific Perspective provides best-practice protocols and guidance in the choice of robust method combinations to deal with many day-to-day challenges in computational chemistry and discusses representative examples.

#workshop #virtual #genomics #beginner #level

Virtual workshop on Introduction to fundamentals and Bash Scripting for Genomics.

This two-day workshop focuses on the basics of genomics and using Linux for genomics. Further, It will provide concepts, and hands-on training on Linux commands noscripts and basics of genomics, such as designing experiments, accessing datasets from different databases, and data uploading to resources like NCBI.

🎙Our speakers, Dr. Meenakshi I (NCBS, India) & Dr.Samdani A (ICOA, France), carry Ph.D. degrees in Bioinformatics with rich of experience in Genomics.

✍️Who can apply?
Anyone interested in learning the basics of Linux and genomics study design and managing sequencing data. The workshop assumes that learners have no or little experience with Linux systems

✳️It is free for Undergraduate students.
