Anodic bonding was used to fabricate a 10 mm diameter × 640 nm tall annular geometry suitable for torsion pendulum studies of confined 3He. For pure 3He at saturated vapor pressure the inertia of the confined fluid was seen to be only partially coupled to the pendulum at 160 mK. Below 100 mK the liquid’s inertial contribution was negligible, indicating a complete decoupling of the 3He from the ...

We report here on the results of experiments concerning particular bonding processes potentially useful for ultimate miniaturization of microfluidic systems. Direct anodic bonding of continuous thin Pyrex glass of 250 pm thickness to silicon substrates gives multiple, large voids in the glass. Etchback of thick glass of 1200 pm thickness bonded to silicon substrates gives thin continuous glass ...

The inhibition action of environmentally sustainable inhibitor Cycas revoluta leaves extract (CRLE) for corrosion protection soft-cast steel in a solution HCl was assessed with electrochemical and chemical methods. eco-friendly forms thin coating on slows the acid media. percent performance, current density, potential, both anodic cathodic slopes Tafel were calculated. results research are bene...

Corrosion protection performance of a completely soluble polyaniline-dodecylbenzenesulfonic acid salt (PANI-DBSA) on C45 steel has been studied with electrochemical impedance and potentiodynamic measurements. Chloroform is the most suitable solvent to process the pristine PANI-DBSA because of negligible interaction of the solvent with the polyaniline (PANI) backbone. An anodic shift in the corr...

The aim of this work was to evaluate the corrosion behavior AA2055 Aluminum-lithium alloy anodized in a sulfuric acid (H2SO4) bath, varying current density 0.19 and 1 A·cm−2 why sealing solution water (H2O) sodium dichromate (Na2Cr2O7). Anodized samples were exposed 10 vol.% H2SO4 electrochemical technique used impedance spectroscopy. Scanning electron microscopy X-ray photoelectron spectroscop...

The tribocorrosion behavior and degradation mechanism of 316L stainless steel, in four typically industrial corrosion media, under different potentials, were studied. results indicated that they strongly depended on medium electrode potential. When the potential increased from cathodic protection region to anodic region, was accelerated. It dramatically promoted mechanical wear which even domin...

The features of the bismuth oxide deposition by ion layering method on matrices anodic alumina and titania have been studied. formed nanostructured systems studied means electron micros copy, X-ray microanalysis, spectroscopy. Two-layer nanocomposites consist porous matrix or TiO 2 island film with vertically oriented Bi O 3 plates placed surface. photoluminescence spectrum Al /Bi structure con...

One-dimensional (1D) Bi-based nanostructures are promising thermoelectric materials and, furthermore, are very interesting systems for studying physical and chemical properties in the nanoscale, owing to their anisotropic character. The main challenges in this area are to control the diameter, orientation, and alloy composition with precision, and thereby to gain ready access to junction and su...
