Synthetic Biology

5.0K
Synthetic biology is an interdisciplinary science that involves using principles from disciplines such as engineering, molecular biology, cell biology, and systems biology. It involves remodeling existing organisms from nature or constructing completely new synthetic organisms for applications such as protein or enzyme production, bioremediation, value-added macromolecule production, and the addition of desirable traits to crops, to name a few.

Combustion Energy: A Measure of Stability in Alkanes and Cycloalkanes

6.6K
The low reactivity in alkanes can be attributed to the non-polar nature of C–C and C–H σ bonds. Alkanes, therefore, were  initially termed as “paraffins,” derived from the Latin words: parum, meaning “too little,” and affinis, meaning “affinity.”
Alkanes undergo combustion in the presence of excess oxygen and high-temperature conditions to give carbon dioxide and water. A combustion reaction is the energy source in natural gas, liquified...

Carbon Skeletons

110.0K
Life on Earth is carbon-based, as all macromolecules that make up living organisms contain carbon atoms. All organic compounds have a carbon backbone. Each carbon atom is tetravalent and can bond with four other atoms, making it an extraordinarily flexible component of biological molecules. Because carbon’s valence electrons are stable, it rarely becomes an ion. As the carbon chain increases in length, structural modifications such as ring structures, double bonds, and branching side...

Conformations of Ethane and Propane02:18

Conformations of Ethane and Propane

14.5K
In an organic molecule, free rotation about the carbon-carbon single bond results in energetically different conformers of the molecule. Due to this rotation, called the internal rotation, ethane has two major conformations — staggered and eclipsed.
Staggered conformation is a low energy and more stable conformation with the C-H bonds on the front carbon placed at 60°dihedral angles relative to the C-H bonds on the back carbon, leading to a reduced torsional strain. In staggered...

Pyruvate Oxidation01:15

Pyruvate Oxidation

161.1K
After glycolysis, the charged pyruvate molecules enter the mitochondria via active transport and undergo three enzymatic reactions. These reactions ensure that pyruvate can enter the next metabolic pathway so that energy stored in the pyruvate molecules can be harnessed by the cells.
First, the enzyme pyruvate dehydrogenase removes the carboxyl group from pyruvate and releases it as carbon dioxide. The stripped molecule is then oxidized and releases electrons, which are then picked up by NAD+...

Área de la Ciencia:

  • Ciencias de los materiales
  • Ciencia de los datos
  • Ingeniería Química

Sus antecedentes:

  • Las propiedades del biocarburante dependen de la materia prima, la modificación y la pirólisis, lo que hace que el diseño de biocarburante diseñado sea complejo.
  • La predicción de las propiedades del biocarburante requiere métodos robustos para manejar la variabilidad y las interdependencias de los datos.

Objetivo del estudio:

  • Desarrollar y evaluar modelos generativos de datos para predecir las propiedades del biocarburante.
  • Identificar el modelo más eficaz para la síntesis de datos de alta fidelidad sobre las propiedades del biocarburante.

Principales métodos:

  • Se desarrollaron cuatro modelos: Red adversaria generativa tabular (TGAN), Red adversaria generativa tabular condicional (CTGAN), Autoencoder variacional tabular (TVAE) y Synthpop.
  • Los modelos fueron entrenados y evaluados en conjuntos de datos de propiedades de biocarbón imputados (n=461).
  • El rendimiento del modelo se evaluó utilizando la similitud de distribución, la preservación de la correlación y la validación experimental.

Principales resultados:

  • Synthpop demostró una calidad de datos sintéticos superior, capturando con precisión varios patrones de distribución.
  • Synthpop logró una alta similitud de distribución (0,97), KSComplement (0,98) y TVComplement (0,95).
  • La validación experimental mostró bajos errores relativos (<5%) para las propiedades clave del biocarburante utilizando datos generados por Synthpop.

Conclusiones:

  • Synthpop es un modelo confiable para sintetizar propiedades de biocarbón pirolizado.
  • El marco desarrollado permite una selección rápida del biocarbón específico de la aplicación.
  • La generación precisa de datos sintéticos puede acelerar la investigación y el desarrollo de biocarbón.
