“…Phase transitions [15,16] or a distortion towards an orthorhombic lattice [17] have been reported to take place at pressures below 6 GPa, but the observations are not very consistent. Recently, the structural behavior of SnO under pressure was investigated by energy-dispersive X-ray diffraction and EXAFS measurements using synchrotron radiation [18]. Furthermore, the effect of pressure on the one-phonon density of states of SnO was measured by nuclear inelastic scattering [19].…”

We have investigated the high-pressure behavior of the 'lone-pair' compound SnO using monochromatic synchrotron X-ray diffraction, synchrotron far-and mid-infrared reflection measurements, and Raman spectroscopy. The litharge-type ambient pressure structure is observed up to at least 20 GPa, though with indications for a small distortion above 15 GPa. Changes in interatomic distances are determined via full Rietveld refinements of diffraction patterns. SnO is found to undergo a semiconductor to metal transition near 5(1) GPa; the transition is attributed to the closure of the indirect fundamental gap. The mode Grüneisen parameters of zone-center Raman mode frequencies are reported. The results are discussed in light of related experimental and theoretical studies of structural, dynamical, and electronic properties of SnO.

Abstract. The structure of an intermediate form of tin oxide was investigated by precession electron diffraction. The results support a revised version of a layered, vacancy-ordered structure for Sn 3 O 4 proposed in the preceding literature. The lattice parameters were found to be consistent with a monoclinic cell which is a distorted superlattice of the cassiterite structure. Zero-order Laue zone (ZOLZ) Patterson maps, phased projections and phases measured from a ½001 first-order Laue zone (FOLZ) conditional Patterson map all support the proposed modification to the tin coordinates over the unmodified form. The results of kinematical refinement were not satisfactory, although weak features found in the Patterson maps were consistent with the oxygen atoms being located close to the previously proposed positions.

ÖZBu çalışmada Li-iyon piller için uyumlu çekirdek olarak kalay (II) oksit anotlar kimyasal indirgeme yöntemi ile sentezlenmiştir. Karbon esaslı kabuk sentezi için mikrodalga destekli karbürizasyon yöntemi kullanılmış ve SnO tozlarının yüzeylerinde ince amorf bir karbon tabakası elde edilmiştir. Üretilen kalay (II) oksit/karbon kompozit elektrotların yüzey morfolojileri Taramalı Elektron Mikroskobu (SEM) ile analiz edilmiş ve yapıların faz bileşenleri X-Işınları Difraktometresi (XRD) ile karakterize edilmiştir. Üretilen kalay (II) oksit/karbon kompozit tozları kullanılarak hazırlanan elektrotlar ile CR2016 test hücreleri hazırlanmış ve elektrotların elektrokimyasal performansı MTI BST8-MA 8 kanallı pil test ünitesinde, oda sıcaklığında 10 mV ve 2,5 V arasında sabit 1C şarj/deşarj şartlarında akım verilerek test edilmiştir. Sonuç olarak, kalay (II) oksit/karbon kompozit elektrot malzemeleri ile 100 çevrim sonrasında 396 mAh g -1 deşarj kapasitesi elde edilmiştir.Anahtar Kelimeler: Kalay (II) oksit, çekirdek/kabuk, kimyasal indirgeme, mikrodalga destekli karbürizasyon, Li iyon pil. The Production and characterization of tin (II) oxide composite anode electrodes for lithium ion batteries ABSTRACTIn this study, the core component of the composite, tin (II) oxide powders synthesized through a facile chemical reduction methods for Li-ion batteries. As the shell structure, surfaces of the as-synthesized tin (II) oxide particles were coated with carbon through microwave assisted carburization process. The surface morphologies and phase components of the as-synthesized tin (II) oxide/carbon composites were investigated via scanning electron microscopy and X-ray diffraction methods, respectively. CR2016 type coin cells were prepared by using tin (II) oxide/carbon composite powders and electrochemical tests were performed at room temperature via 8-channel MTI BST8-MA electrochemical test station between 10 mV and 2.5 V potential range by applying fixed 1 C state of charge conditions. The results have shown that tin (II) oxide/carbon composite structure have significantly improved the specific capacities to 396 mAh g-1 after 100 cycles. sea takimata sanctus est Lorem ipsum dolor sit amet, consetetur sadipscing elitr, sed diam * nonumy eirmod tempor invidunt ut lab ore sit et dolore magna
