Three different procedures are used to deposit aluminium onto O-terminated (100) and (111) boron-doped diamond, with the aim of producing a thermally stable surface low work function negative electron affinity. The methods 1) deposition > 20 nm film Al by high-vacuum evaporation followed HCl acid wash remove excess metallic Al, 2) <3 Å atomic layer deposition, 3) thin-film beam evaporation. str...

In this work, the effect of presence of the sodium tripolyphosphate (STPP), as an inorganic salt, on improving the performance of polyamide (PA) thin layer membranes has been studied. Characterization analyses confirmed the presence of the salt on the whole surface structure of the thin layer. Different salt loadings resulted in different fluxes and Cu (II) rejections. The thin layer containing...

Evaporation process, the main component of the water cycle in nature, is essential in agricultural studies, hydrology and meteorology, the operation of reservoirs, irrigation and drainage systems, irrigation scheduling and management of water resources. Various methods have been presented for estimating evaporation from free surface including water budget method, evaporation from pan and experi...

the objective of this study was to investigate the drying kinetics of oyster mushroom, pleurotus ostreatus mushrooms were dried using a cabinet-type convective dryer. air temperatures of 50, 60 and 70 oc were used for the drying experiments. the experimental drying data were fitted to different theoretical models to predict the drying kinetics. nonlinear regression analysis was performed to rel...

The theory of coronal evaporation predicts the formation of an inner hole in the cool thin accretion disk for mass accretion rates below a certain value (≈ 1/50 of the Eddington mass accretion rate) and the sudden disappearance of this hole when the mass accretion rate rises above that value. The inner edge of the standard thin disk then suddenly shifts inward vvvvfrom about a few hundred Schwa...

Spontaneous ordering of nanoparticles (NPs) occurring as a consequence of solvent evaporation can yield highly ordered and extended NP superlattices bearing both fundamental scientific interest and potential for technological application. A versatile experimental chamber has been developed allowing (i) controlled in situ deposition of NP solutions on solid substrates, (ii) rate-controlled evapo...

Background: Approximately one quarter of all nosocomial infections can be attributed to the urinary tract. The infections are supposed to be mainly caused by implantations of urethral catheters and stents. A new catheter design is introduced with the aim to lower the high number of nosocomial urethral infections. In order to avoid limitations to use, the design is first applied to conventional ...

When a polymer solution with volatile solvent is exposed to open air, an elastic layer (called a skin) is often formed at the surface of the solution due to evaporation of the solvent. After such a skin is formed, further extraction of the solvent from the solution caused by evaporation has generally been considered to reduce the pressure in the solution. We have found that, in PMMA/acetone dro...
