Corrosion under insulation (CUI) occurs from electrochemical reactions on the surface of thermally insulated industrial equipment and has water as an electrolyte. CUI generates many costs for companies due to maintenance can also cause problems human environmental integrity. In this work, vast bibliographic research was carried out corrosion insulation, in articles published between 1998 2022, ...

Cu3N with a cubic crystal structure is obtained in this paper by the sputtering of Cu under N2 followed annealing NH3: H2 at 400 °C, after which it was doped iodine room temperature resulting into p-type hole densities between 1016 and 1017 cm−3. The exhibited distinct maxima differential transmission ~2.01 eV 1.87 as shown ultrafast pump-probe spectroscopy, corresponding to M R direct energy b...

The mononuclear complex [Cu(L)(CH3CN)(PPh3)]ClO4, (1), (L= 2,5-diphenyl-3,4-bis(2-pyridyl)cyclopenta-2,4-dien-1-one), has been synthesized and investigated by elemental analysis, IR, 1H NMR, UV-Vis spectroscopic methods and X-ray diffraction. The complex crystallizes in the non-centrosymmetric space group P212121 in accord with the asymmetric (atropisomer) Cu centre. Its coordination polyhedron...

In 2019, media reports raised awareness about privacy and security violations in Conversational User Interfaces (CUI) like Alexa, Siri Google. Users report that they perceive CUI as creepy are concerned their privacy. The European General Data Protection Regulation (GDPR) several other laws across the globe, give users right to control processing of data, for example by requesting deletion data...

We report a neutron scattering study on the tetragonal compound Sr2Cu3O4Cl2, which has two-dimensional (2D) interpenetrating CuI and CuII subsystems, each forming a S=1/2 square lattice quantum Heisenberg antiferromagnet (SLQHA). The mean-field ground state is degenerate, since the intersubsystem interactions are geometrically frustrated. Magnetic neutron scattering experiments show that quantu...
