“…Two proposed mechanisms for the effect of COS are: the formation of nickel sulphide or poisoning of the surface of the particles. Information available in the literature shows that the free energy of adsorptions of sulphur on a metal is lower than that for the formation of a stable sulphide [13,[17][18][19][20]. Much of the work available in the literature has been conducted where the sulphur species originates from H 2 S. The information provided is, however, relevant to the low oxygen partial pressures experienced in the conditions in this research.…”

In this paper, the results of a systematic study of the effect of temperature and COS concentration on the formation of carbon deposits on a 20Cr25Ni austenitic stainless steel under a depositing gas of 1000 vppm ethene in 1%CO/CO 2 have been presented. Carbon deposits were found over the temperature range of 550-725°C after 4 h exposure. COS additions to the ethene-bearing gas inhibited 123Oxid Met (2017) 87:667-678 DOI 10.1007 the deposition process, but the effect was concentration and temperature dependent. The results have been interpreted in terms of the oxidation process and the adsorption of sulphur on the catalytic Ni-rich particles.

“…Noble metals, such as Pd, platinum (Pt), gold (Au), rhodium (Rh), and their alloys are usually used as the electrodes as well as catalysts, which increase the total cost of the conversion process [24,29]. Transition metals and their complexes, such as [Pd(triphosphine)(PR 3 )](BF 4 ) 2 , aza-macrocyclic complexes of Ni (II), Co (II), and Cu (II), and [Pd(triphosphine)-(CH 3 CN)] 2+ can also be used as the catalysts in this process [23,25,30,31].

Energy issues are important and consumption is slated to increase across the globe in the future. The energy-environment nexus is very important as strategies to meet future energy demand are developed. To ensure sustainable growth and development, it is essential that energy production is environmentally benign. There are two temporal issues-one that is immediate, and needs to address the environmental compliance of energy generation from fossil fuel sources; and second that is the need to develop newer alternate and more sustainable approaches in the future. Aerosol science and technology is an enabling discipline that addresses the energy issue over both these time scales. The paper is a review of aspects of aerosol science and engineering that helps address carbon neutrality of fossil fuels. Advanced materials to meet these challenges are discussed. Future approaches to effective harvesting of sunlight that are enabled by aerosol studies are discussed.

“…An important aspect is the incorporation of transition metals into the chemistry of p-block elements other than carbon [45][46][47]. The literature contains numerous examples for boron, but other elements illustrate the possibilities as well [48,49]. The chemistry of transition-metal complexes with main group elements, particularly with chalcogen ligands, are of substantial importance.…”

Synthesis of Trithia-Borinane Complexes Stabilized in Diruthenium Core: [(Cp*Ru)2(η1-S)(η1-CS){(CH2)2S3BR}] (R = H or SMe)

The thermolysis of arachno-1 [(Cp*Ru)2(B3H8)(CS2H)] in the presence of tellurium powder yielded a series of ruthenium trithia-borinane complexes: [(Cp*Ru)2(η1-S)(η1-CS){(CH2)2S3BH}] 2, [(Cp*Ru)2(η1-S)(η1-CS){(CH2)2S3B(SMe)}] 3, and [(Cp*Ru)2(η1-S)(η1-CS){(CH2)2S3BH}] 4. Compounds 2–4 were considered as ruthenium trithia-borinane complexes, where the central six-membered ring {C2BS3} adopted a boat conformation. Compounds 2–4 were similar to our recently reported ruthenium diborinane complex [(Cp*Ru){(η2-SCHS)CH2S2(BH2)2}]. Unlike diborinane, where the central six-membered ring {CB2S3} adopted a chair conformation, compounds 2–4 adopted a boat conformation. In an attempt to convert arachno-1 into a closo or nido cluster, we pyrolyzed it in toluene. Interestingly, the reaction led to the isolation of a capped butterfly cluster, [(Cp*Ru)2(B3H5)(CS2H2)] 5. All the compounds were characterized by 1H, 11B{1H}, and 13C{1H} NMR spectroscopy and mass spectrometry. The molecular structures of complexes 2, 3, and 5 were also determined by single-crystal X-ray diffraction analysis.
