Efficient catalytic conversion of NO2 to non-harmful species remains an important target for research. State-of-the-art deNOx processes are based upon ammonia (NH3)-assisted selective reduction (NH3-SCR) over Cu-exchanged zeolites at elevated temperatures. Here, we describe a highly efficient non-thermal plasma (NTP) process catalyzed by Cu-embedded metal-organic framework, Cu/MFM-300(Al), room...

To bond a semiconductor power chip on substrate using the formation of bondlines exhibiting long-term mechanical durability at high temperatures such as 300 °C, compression-assisted sinter bonding between Cu finishes was carried out 300–350 °C in air. flakes approximately 7 µm were used main filler material; their surfaces modified by pretreatment formic acid solution, and existing oxide layers...

For Y B a 2 C u 3 0 7 _ a powder samples of different average grain sizes the temperature dependences of 6 Cu NQR frequencies and signal intensities are reported for the Cu (1) site in a temperature range of 4 300 K. Both quantities show a non-monotonic behaviour in the vicinity of the superconduction transition temperature Tc. In the superconducting state the line shape of the NQR signal in ze...

63-65Cu and 79,81Br spectra of halogenocuprate (I) complexes containing [CuPPh3 X2]~ (X = C1, Br, I) anions with different cations were recorded in the range 77 K -300 K. The results confirm the previous trend that, for a given ligand, 63Cu NQR frequencies are in the order C l> B r> I. fe3Cu NQR frequencies in [CuPPh3 X2]_ are compared with those in neutral Cu(Ph3 )2 X(X = Cl, Br) complexes and...

In situ high-temperature X-ray diffraction was used to investigate the reaction mechanism and kinetics of CuGaSe2 formation from Cu–Ga precursors during selenization. The precursor films were deposited in a migration enhanced molecular beam epitaxial reactor on Mo-coated thin glass substrates. During the selenization CuSe forms in the temperature range of approximately 260 to 370 °C, and the on...

The two-dimensional, free-electron-like band structure of noble metal surfaces can be radically transformed by appropriate nanostructuration. A case example is the triangular dislocation network that characterizes the epitaxial Ag/Cu(111) system, which exhibits a highly featured band topology with a full band gap above E(F) and a hole-pocket-like Fermi surface. Here we show that controlled dopi...

It is interesting to imagine what would happen when a mixture of soft-boiled eggs and stones is deformed together. A foil made of pure Ti is stronger than that made of Cu. When a composite Cu/Ti foil deforms, the harder Ti will penetrate into the softer Cu in the convex shapes according to previously reported results. In this paper, we describe the fabrication of multilayer Cu/Ti foils by the r...

Pulsed laser deposition (PLD) has been used to grow epitaxially oriented thin films of Cu and Pt on (100)-oriented substrates of both SrTiO3 and LaAlO3. The resulting films have been characterized for their crystalline orientations using x-ray diffraction (XRD) and for their surface morphologies using atomic force microscopy (AFM). The diffraction results illustrated that purely epitaxial Cu(10...
