Hi @LatinXChem, presenting an automated protocol for building #biochar atomistic models guided by experimental characterization data and validated against laboratory observables at #LatinXChem24 #LatinXChemComp #Comp008
Check out the structures: https://t.co/nDxMGGHq0a

@rgraucrespo @LatinXChem We used two main metrics, ultimate analysis (C,H,O, and N) and CNMR data to fix the structure, with a confidence of 90% compared with experimental data.

@rgraucrespo @LatinXChem Thanks for your question. It would be applicable if the carbon-based material is between the range of applicability of the code for the H/C and O/C molar ratios.

@maykcaldas @LatinXChem They are incorporated from the beginning, considering the C NMR data that quantifies the amount of defective carbon in the sample. So, we consider all these constraints to select fragments with defects to accommodate this feature in the model.

@maykcaldas @LatinXChem Hi! Thanks for your question. Each model has about 10,000 atoms. Biochar is a particular type of charcoal made from agroindustrial waste. It helps soil by holding water and nutrients and traps carbon, which is good for the environment.

@Bancolombia hay alguna manera de cancelar la cuenta de ahorros que tengo con ustedes si estoy en el extranjero? He tratado de cancelarla hace 3 meses y en el chat de atención al usuario siempre quedan en llamarme para realizar el proceso y nunca lo hacen... que puedo hacer?

Do not use your energy to worry. Use your energy to believe, to create, to learn, to think and to grow.

Hi everyone!
I developed a project in Fortran, it is possible to connect it to Aspen plus, as a calculator or as a USER model?
How I could do it?
