Photoinduced changes in the electronic structure of As 2 Se 3 glass
In situ irradiation experiments were performed on the oxygen-free surface of bulk As2Se3 glass that was fractured in the UHV environment of the X-ray photoelectron spectroscopy (XPS) chamber. The results are in agreement with theoretical simulations, which predict a large concentration of valence alternation pairs in this glass. Compared to previous experiments conducted in air, we find relativ...
متن کاملEffect of physical aging on fracture behavior of Te 2 As 3 Se 5 glass fibers
Fracture surface characteristics of Te2As3Se5 (TAS) glass fibers aged in light and in dark have been investigated respectively for understanding physical aging effect on their fracture behavior. The properties including tensile strength ( ), surface flaw depth ( ), and mirror radii (rm) were measured by DY30 Adamel Lomarghy and SEM respectively. Shape factor extracted by fitting of vs confirms ...
متن کاملInhibitive Assessment of N-(8-bromo-3H-phenoxazin-3-ylidene)-N,N’-Dimethylaminium, as a Novel Corrosion Inhibitor for Mild Steel in 1.0 M HCl
The inhibition effect of N-(8-bromo-3H-phenoxazin-3-ylidene)-N,N’-dimethylaminium (DPhDMA) on the corrosion behavior of mild steel in 1.0 M HCl solution has been studied. Weight loss measurements, potentiodynamic polarization, electrochemical impedance spectroscopy (EIS) and quantum chemical calculations were used in this study. Electrochemical results revealed that DPhDMA is an effective mixed...
متن کامل2 3 Se p 20 05 Associativity as Commutativity
It is shown that coherence conditions for monoidal categories concerning associativity are analogous to coherence conditions for symmetric strictly monoidal categories, where associativity arrows are identities. Mac Lane’s pentagonal coherence condition for associativity is decomposed into conditions concerning commutativity, among which we have a condition analogous to naturality and a degener...
متن کاملThe effect of hydrogen bonding on the conformations of 2-(1H-indol-3-yl)-2-oxoacetamide and 2-(1H-indol-3-yl)-N,N-dimethyl-2-oxoacetamide.
In the title compounds, C(10)H(8)N(2)O(2), (I), and C(12)H(12)N(2)O(2), (II), the two carbonyl groups are oriented with torsion angles of -149.3 (3) and -88.55 (15)°, respectively. The single-bond distances linking the two carbonyl groups are 1.528 (4) and 1.5298 (17) Å, respectively. In (I), the molecules are linked by an elaborate system of N-H···O hydrogen bonds, which form adjacent R(2)(2)(...
