WebPlotDigitizer has been updated

 

I just noticed that WebPlotDigitizer has recently been updated.

It is often necessary to reverse engineer images of data visualizations to extract the underlying numerical data. WebPlotDigitizer is a semi-automated tool that makes this process extremely easy.

More details on the Data Analysis Tools Page.

Mobile Science Apps updated

 

A couple of the Apps on the Mobile Science site have been updated.

Most notably the Human Anatomy Atlas, which is currently the fifth most viewed app on the site.

3rd RSC-BMCS / RSC-CICAG Artificial Intelligence in Chemistry

 

Registration is open!!

Synopsis.
Artificial Intelligence is presently experiencing a renaissance in development of new methods and practical applications to ongoing challenges in Chemistry. Following the successes of two “Artificial Intelligence in Chemistry” meetings in 2018 and 2019, we are pleased to announce that the Biological & Medicinal Chemistry Sector (BMCS) and Chemical Information & Computer Applications Group (CICAG) of the Royal Society of Chemistry are once again organising a conference to present the current efforts in applying these new methods. The meeting will be held over two days and combine aspects of artificial intelligence and deep machine learning methods to applications in chemistry

The Call for Abstracts is Open.
Applications for both oral and poster presentations are invited. Posters will be displayed during a dedicated poster session and, at the time of submission, applicants are asked if they wish to provide a two-minute lightning oral presentation. The closing date for all submissions is Friday, 31st July.

There will be a mix of plenary and keynote talks as well as poster sessions with some lightning poster talks. There will also be exhibitor sessions, and we are currently exploring options for providing breakout rooms for discussions.

MOPAC updated

 

A new version of MOPAC has been released full details are in this publication "A New Release of MOPAC Incorporating the INDO/S Semiempirical Model with CI Excited States" DOI.

We have incorporated the semiempirical INDO/S Hamiltonian into a new release of MOPAC2016, which has long been at the forefront of semiempirical quantum chemical methods (SEQMs). Our new code enables the calculation of excited states using the INDO/S Hamiltonian combined with a configuration interaction approach using single excitations (CIS), single and double excitations (CISD), or multiple reference determinants (MRCI) where reference determinants are generated using a complete active space (CAS) approach. The capacity to perform excited-state calculations beyond the CIS level makes INDO/CI one of the few low-cost computational methods capable of accurately modeling states with substantial double-excitation character. Solvent corrections to the ground-state and excited-state energies can be computed using the COSMO implicit solvent model, incorporating state-specific corrections to the excited states based on the solvent refractive index. We demonstrate that this code produces physically reasonable electronic structures, absorption spectra, and solvatochromic shifts at low computational costs for systems up to hundreds of atoms, and for both organic molecules and metal clusters.
