The synthesis of furanic derivatives (5-hydroxymethylfurfural (HMF), furfural . . . ) from carbohydrates is of high interest for a wide range of applications. These reactions are carried out in the presence of various solvents, and among them choline chloride can be used. It is a salt that can form a low melting mixture with a carbohydrate (fructose, glucose . . . ) or a deep eutectic mixture w...

Laser remelting has been performed on Ni-30 wt.% Sn hypoeutectic alloy. An anomalous eutectic formed at the bottom of the molten pool when the sample was remelted thoroughly. 3D morphologies of the α-Ni and Ni3Sn phases in the anomalous eutectic region were obtained and investigated using serial sectioning reconstruction technology. It is found that the Ni3Sn phase has a continuous interconnect...

Organic semiconductors including rubrene, Alq3, copper phthalocyanine and pentacene are crystallized by the eutectic melt crystallization. Those organic semiconductors form good eutectic systems with the various volatile crystallizable additives such as benzoic acid, salicylic acid, naphthalene and 1,3,5-trichlorobenzene. Due to the formation of the eutectic system, organic semiconductors havin...

NiTi wires were brazed together via eutectic reaction between NiTi and Nb powder deposited at the wire contact region. Phase transformation and deformation behavior of the NiTi-Nb eutectic microstructure were investigated using transmission electron microscopy (TEM) and cyclic loading-unloading tests. Results show that R phase and B19' martensite transformation are induced by plastic deformatio...

The competitive growth mechanisms of ternary eutectic and peri-eutectic transitions liquid Fe–Ni–Ti alloys were investigated by drop tube technique. As undercooling cooling rate increased, the microstructure Ni40.6Fe36.4Ti23 alloy transformed from mixture primary Ni3Ti phase into complete eutectic. predominant mode independently grown Fe2Ti intermetallic varied nonfaceted to faceted growth, whi...

copper–silver bimetallic strips were produced by cold roll welding process and were treated by diffusion annealing in the temperature range 250–800 ?c. the interface bonding strength was determined by bending and peeling tests, resistance, conductivity and micro hardness profiles were determined and microstructure in the interface region was observed by optical microscope. electrical resistance...

Medazepam, citric acid and their binary mixtures were studied using differential scanning calorimetry (DSC) Fourier transform infrared spectroscopy (FTIR) for thermal structural properties. The DSC data show a simple eutectic peak at 370 K. To determine the exact mole fraction which occurs, Tamman’s triangle was used. obtained results that mixture appears molar of medazepam approximately 0.85. ...
