Increasing Trend

In the last decade, there has been an increasing trend in the exploitation of indium chalcogenides in various applications which range from water splitting reactions in renewable energy to degradation of dyes in environmental rehabilitation. This trend is attributed to the interesting and unique properties of indium chalcogenide nanomaterials which can be easily tuned through a common approach: particle size, shape and morphology engineering. In this chapter, we outline the preferred attributes of indium chalcogenide nanomaterials which are deemed suitable for recent applications. Furthermore, we explore recent reaction protocols which have been reported to yield good quality indium chalcogenide nanomaterials of multinary configurations, e.g. binary and ternary compounds, among others.

With the increasing trend of mechanized harvesting of green sugarcane the trash residue needs to be used. Leaving large amounts of trash remaining on the field can sometimes lead to problems such as delay of sprouting of tillers, increased levels of leafhopper infestation and difficulty of tillage operation. Windrowing of trash after harvesting can minimize these problems. To eliminate the operation of trash windrowing and to facilitate the trash decomposition, the Sugarcane Technology Center, CTC (Centro de Tecnologia Canavieira), Brazil developed a trash shredder system for a primary extractor of John Deere chopper sugarcane harvester. Using rotating knives all vegetable material passing through the primary extractor is chopped, thereby reducing the particle size. After some adjustments, preliminary tests were carried out to prove the efficiency of chopping and sugarcane cleaning. The machine produces a much smaller trash particle size than conventional harvesters. The system shows promise in shredding trash either for use at the mill or for dispersion on the field.

Recent Insight

Light-driven water oxidation occurs in oxygenic photosynthesis in photosystem II and provides redox equivalents directed to photosystem I, in which carbon dioxide is reduced. Water oxidation is also essential in artificial photosynthesis and solar fuel-forming reactions, such as water splitting into hydrogen and oxygen (2 H2O + 4 hν → O2 + 2 H2) or water reduction of CO2 to methanol (2 H2O + CO2 + 6 hν → CH3OH + 3/2 O2), or hydrocarbons, which could provide clean, renewable energy. The “blue ruthenium dimer,” cis,cis-[(bpy)2(H2O)RuIIIORuIII(OH2)(bpy)2]4+, was the first well characterized molecule to catalyze water oxidation. On the basis of recent insight into the mechanism, we have devised a strategy for enhancing catalytic rates by using kinetically facile electron-transfer mediators. Rate enhancements by factors of up to ≈30 have been obtained, and preliminary electrochemical experiments have demonstrated that mediator-assisted electrocatalytic water oxidation is also attainable.
