A big amount of vanadium is used in the industry. It is used as a vanadium carbide stabiliser in steel production. Only $ 0.5\% $ 0.5 % vanadium in an iron alloy will double the tensile strength. Vanadium salts are used in leather, ink, dye manufacturing and yellow ceramic glaze. On the other hand, vanadium pentoxide is used as a catalyst, in the chemical industry, for the production of sulphuric acid and in the petroleum refinery industry. Resolvability parameter is the most discussed topic in graph theory. This helps to reorganise a network in a unique way, sometimes in terms of atoms (metric dimension) and sometimes bound (edge metric dimension). We studied resolvability parameters of vanadium carbide network in this article i.e. metric, edge metric and partition dimension. Among these metrics resolvability defined by parameters taking a subset from the set of vertices, if it has a unique representation with all the vertices, then it is called a resolving set. The number of elements in the smallest resolving set is called the metric dimension. While the number of elements of the minimal subset of vertices taking from vertex set is called the edge metric dimension, if the representations are unique of all edges and the set is called the edge resolving set. This study can have an effect in many ways in the research, particularly, with the help of some key points such as network structure analysis, material science via material properties, graph theory applications, predictive modelling, material testing and characterisation, as well as in industrial applications.

A form of porous polymeric material known as metal-organic frameworks is made up of metal ions connected by organic bridging ligands. Entropy is used as a complexity indicator for graphs and is regarded as the graph's structural information content. The graph entropies have evolved into information-theoretic variables for computing the structure information of chemical graphs. The potential use in chemistry of the graph entropy portion has gained the attention of the research community. In this article, we investigate the explicit expressions of graph entropies for two categories of metal organic frameworks (MOFs) named as, $ M_{1}TPyP-M_{2} $ M 1 TPyP − M 2 (TPyP= 5, 10, 15, 20-tetrakis (4-pyridyl) porphyrin and $ M_{1}, M_{2} $ M 1 , M 2 = Fe and Co) MOFs and butylated hydroxytoluene-(BHT-) based metal-organic (M= Co, Fe, Mn, Cr) (MBHT) frameworks. we compute some numeric values for certain graph entropies in Tables. In the last, we present a comprehensive graphic comparison of our new results. [ABSTRACT FROM AUTHOR]

Complex networks are difficult to understand and deal with, yet building a graph of any complex and huge structure, whether chemical or computer-related, is quite straightforward. In the form of a graph theory view, it becomes simple to design networks. Each component's recognition is aided by the ease of its production in the form of graph theory. Finding a vertex (node or atom) in a structure is similarly difficult; in this instance, resolvability parameters come into play. This technique plays a significant role in managing or allowing access to each vertex in relation to some chosen vertices called a resolving set that shapes an entire cluster of vertices into a unique form and every single vertex is easy to recognise or locate, whether the small or large the structure. This article contributes the bounds on the parameter of partition dimension of chemical complexes in dialkyltin of supramolecular chain from N-Salicylidene-L-Valine. We supposed the complexes of chains from 2,3,4 and another chemical network, and we demonstrated that the number of vertices has a significant impact on the composition of resolving partition sets.

This paper presents a goal programming model to predict the kinetic parameters of micro fluidized bed (Micro-FB) gasification of woody biomass in Qom, Iran. Qom has an abundance of waste woody biomass, and gasification can convert this residue into clean syngas. To do this, a kinetic model of biomass gasification was developed and validated against the experimental data available in the literature. The experiments were carried out in a Micro-FB in the presence of silica sand as the fluidization medium. To fully decompose the aromatic tars, the reaction temperatures were considered between 700°C and 1000°C with 100°C intervals. Results showed that the obtained activation energies strongly depend on the particle size for all the tested conditions. [ABSTRACT FROM AUTHOR]
