There is intense interest in graphene in fields such as physics, chemistry, and materials science, among others. Interest in graphene's exceptional physical properties, chemical tunability, and potential for applications has generated thousands of publications and an accelerating pace of research, making review of such research timely. Here is an overview of the synthesis, properties, and applications of graphene and related materials (primarily, graphite oxide and its colloidal suspensions and materials made from them), from a materials science perspective.

Insight into the oxidation of phenolic pollutants by enhanced permanganate with biochar: The role of high-valent manganese intermediate species.

The last decade has witnessed a great interest on the application of evolutionary algorithms, such as genetic algorithm (GA), particle swarm optimization (PSO) and gene expression programming (GEP), for optimization problems. This paper presents a hybrid algorithm by combining the GEP algorithm and the orthogonal design method. A multiple-parent crossover operator is introduced for the chromosome reproduction using the orthogonal design method. In addition, an evolutionary stable strategy is also employed to maintain the population diversity during the evolution. The efficiency of the proposed algorithm is evaluated using three benchmark problems. The results demonstrate that the proposed hybrid algorithm has a better generalization ability compared to conventional algorithms.

Cross-border E-commerce has grown exponentially in the past decade in global market. To gain global competition in product-convergent markets, China¿s over 200 thousands cross-border E-commerce businesses have focused more on the service and cost control of supply chain downstream. In this study, we analyse three strategic cost control measures, summarise ten evaluation criteria for cost and develop an evaluation method for cost control using an extended COmplex PRoportion ASsessment (COPRAS) method, named L-COPRAS. This method is proposed to deal with uncertain or linguistic expression on strategic cost measures with varied weights to different alternatives. A case study of helping a Chinese Ecommerce business to select strategic cost control measure on supply chain downstream is conducted. This study indicates that the proposed method is able to deal flexibly with uncertain information in supply chain downstream strategic cost evaluation.
