“…[10] Further demand for H 2 O 2 is driven from its application in chemical synthesis ( Figure 2) with typical applications of H 2 O 2 found in the integrated HPPO process [12][13][14][15][16][17][18][19] and the ammoximation of cyclohexanone to cyclohexanone oxime, a key intermediate in the formation of Nylon-6. [20][21][22][23] These routes for chemical synthesis have, in-part, been driven by the discovery of TS-1 by Enichem in 1983. [24] With the utilisation of H 2 O 2 in tandem with TS-1 and other titanosilicates, [25][26][27][28] finding further application in a number of key processes including, aromatic hydroxylation, [29][30][31] alkane oxidation [32][33][34] and alkene epoxidation.…”

Hydrogen peroxide (H2O2) is a highly effective, green oxidant that has found application in sectors ranging from the synthesis of fine chemicals and waste stream treatment to the extraction of precious metals and the bleaching of paper pulp and textiles. The growing demand for H2O2 has seen it become one of the 100 most important chemicals in the world. The direct synthesis of H2O2 from H2 and O2 has been a challenge for the scientific community for over 100 years and represents an attractive alternative to the current means of production. Herein we discuss the historical perspective of the direct synthesis process, the recent literature regarding catalyst design and the role of additives as well as the application of H2O2 as an in situ oxidant. We discuss the key problems that remain and conclude that although there has been progress with respect to the selectivity of hydrogen utilisation, there is a need to now concentrate on catalyst activity as the key remaining problem requiring a solution is the concentration of H2O2 that can be achieved, especially in flow reactors.

“…The critical angle b r ¼ 55.6 determined from equation (11), at which the robot rolls over, because the reaction force R Cy ¼ 0, is shown with a blue horizontal line. It can be seen that when h o ¼ 47.5 mm, the graph crosses the critical angle b r for which the robot rolls over.…”

The purpose of this work is to investigate the possibilities of climbing higher obstacles while maintaining the overall dimensions of a walking robot through design improvements and experiments. An original concept for the design of a walking robot with a minimum number of motors is presented. Geometric and force constraints for overcoming an obstacle and the conditions for maintaining static stability are determined. Experiments for overcoming a vertical obstacle are conducted with a 3D printed model. The 3D printed robot feet with different shapes and materials are used. The results of the experiments are presented graphically as a percentage of success against a baseline model. In this study, a dimensionless index to compare the height of the overcome obstacle and the dimensions of the robot is introduced. It allows to objectively compare the possibilities of overcoming obstacles between various types of mobile robots. Conclusions and guidelines for design improvements are made.

“…15) Thus, more consideration should be given on actual production modes and process rules in SMCC to raise the validity of scheduling models and solving algorithms. Liu et al 16) summarized the operation principles and control strategies for steelmaking system and indicated the "furnace-caster matching" was the primary principle to keep high-efficiency operation in SMCC. Wang et al 17) presented the static scheduling models by introducing the rules of converter-caster matching and designed the dynamic scheduling approaches based on the flexibilities of refining furnace in processing time.…”
