Proper description of chemical structure diversity is necessary for a coal model in exploring the coal pyrolysis mechanism by reactive molecular dynamics (ReaxFF-MD) simulation. This paper presents a strategy for constructing large and reasonable coal models manually with varied chemical structures. A multicomponent molecular model containing 23,898 atoms was constructed for Fugu subbituminous coal following the proposed strategy on the basis of characterization data obtained from the proximate and ultimate analysis, 13C NMR, and solvent extraction experiments. The model consists of 75 macromolecules of 20 varied average structures for structural diversity and 29 varied small compounds to capture the mobile phase. The elemental composition and key structural parameters of the multicomponent model agree with the analytical data of Fugu coal sample on the whole. The weight loss profile obtained from slow heat-up (2 K/ps) ReaxFF-MD simulations agrees fairly with the observations from thermogravimetric experiments reported in the literature. The temporal evolution of a representative product (C2H4) from long-time (2000 ps) isothermal ReaxFF-MD simulations shows qualitative agreement with the results of the synchrotron radiation vacuum ultraviolet photoionization time-of-flight mass spectrometry (SVUV-PI-TOF-MS) pyrolysis experiments. These examinations indicate the applicability of the constructed model in ReaxFF-MD simulations to explore the coal pyrolysis mechanism. The proposed strategy suggests a feasible approach for manually constructing reasonable large coal models based on limited conventional characterization data.

Cellulose is the most abundant biomass resource in the world. It can be transferred to various water soluble derivatives, biochemicals, and materials. In the second half of the 20th century, nanocellulose was extracted with unique properties such as optical transparency, high strength, and high surface area. These new forms of cellulose can be combined with other materials, mainly biopolymers, to form multifarious composites, which are used in all applications of human life. For convenience, to introduce the recent development of these cellulose-based functional composites, we divided them to seven categories, including biological applications, water treatment, sensor, reinforcing agent, energy storage materials, Pickering emulsion stabilizer, and other versatile applications. The preparation, properties, and applications of these functional composites were depicted.

“…Modificación química del almidón: esterificación. Con el fin de anclar las sustancias orgánicas fotoactivas al almidón fue necesaria su esterificación, previa con anhídrido succínico, empleando piridina e hidróxido de sodio, como sistema catalizador (Martins et al 2014). La esterificación del almidón nativo fue identificada mediante Espectroscopia de Infrarrojo Transformada de Fourier (por sus siglas en idioma inglés Fourier Transform Infrared Spectroscopy, FTIR) (Fang et al 2004).…”

The results showed that the anchoring of the photoactive substances to the esterified starch optimizes the values of water solubility, transparency, acid-base stability and resistance to rupture of the biofilms. The greater photoactive protection was obtained with the biofilm of Rutin, reducing in 66.6% and 57.3% the oxidative degradation of proteins and lipids respectively. It is concluded that the esterification of residual potato starch and its subsequent anchoring of photoactive substances confers a potential use in the production of biodegradable food packaging.
