The corrosion resistance of MoNb/AlNd/MoNb film during different sputter conditions was studied for G6 rotating target sputter equipment. The results show that with the increase of sputter power and the increase of the thickness, top MoNb tends to form coarse columnar crystals, and the corrosion resistance of the metal thin films, at first, increases and then decreases with the increase of sputter power and metal thickness. As the sputter temperature increases, top MoNb tends to form coarse grains while the corrosion resistance of the film is poor. The result also release that with the increase of the target speed, top MoNb film becomes loose so that it is difficult to play a protective role because of its poor corrosion resistance ability. Under the same conditions, the sputter of the planar target film is denser; as a result, the top MoNb layer can protect the inner AlNd layer from corrosion.

Wastewater of Gambier (Uncaria gambier Roxb) is a byproduct of pressing gambier leaves used for textile dyes. This wastewater cannot be stored for a long time to ease the moldy and rot process. The use of textile dye directly requires several long process steps. The study's purpose was to make a natural liquid dyestuff from gambier wastewater using varying mordant concentrations and test the quality of the dyestuff on cotton fabrics. The gambier wastewater was reacted with the FeSO 4 mordant to form a concentrated liquid used directly to dye textiles in a rapid and straightforward process. The study investigated varying the concentration of the FeSO 4 mordant from 1 to 5% (by weight). The reaction between wastewater and mordant was conducted while being stirred at 300 rpm and 70 o C for 30 minutes. It was generated a dark green liquid dyestuff. The concentration of FeSO 4 influenced the color strength (K/S) of the dyestuff and resulted in K/S values from 2.49-3.70. This dyestuff-colored cotton cloth a greenish-grey color. The resulting color depth depended on diluting the dyestuff with K/S values ranging from 6.34 to 12.64. The color fastness against washing, sunlight, and rubbing varied from reasonably good (2-3), good (4), and very good (4-5). It was observed that after a year of storage, the dyestuff retained its color, was stable and showed no visible sign of mold contamination, and was still able to dye the fabric effectively.

BACKGROUND: microRNA (miRNA) molecules are considered as biomarkers and have promising future for early-stage cancer diagnosis. Lawsone (Law) enriched carbon nanofibers (CNFs) were prepared via electrospinning process for the selective miRNA detection. Anti-miRNA molecules were attached on the CNFs immobilized screen printed electrodes (SPE) and used for the detection of miRNA molecules by observing guanine oxidation signal via differential pulse voltammetry (DPV) method. Three different miRNA molecules including the target (miRNA), single-base mismatched (SM.miRNA) and non-complementary (NC. miRNA) were hybridized with the previously attached anti-miRNA molecules (with guanine [PolyT(G)] and without guanine [PolyT(I)]) on the CNFs immobilized SPE surfaces.RESULTS: Guanine oxidation signal decreased after the hybridization of miRNA with anti-miRNA molecules on CNF immobilized SPE surfaces. Guanine oxidation signal was not detected on the PolyT(I) attached samples, but the existence of guanine oxidation signal was clear detected after the addition of miRNA molecules on the previously attached PolyT(I). Because no hybridization of anti-miRNA molecules with the non-complementary miRNA (NC.miRNA) molecules occurred, the guanine oxidation signal was not significantly decreased after the interaction of NC.miRNA with the attached PolyT(G). Since there was no hybridization between the NC.miRNA molecules with the attached PolyT(I) on the SPEs, weak guanine peaks were detected at PolyT(I)-NC.miRNA samples as a result of the existence of residual NC.miRNA molecules on SPE after washing. CONCLUSIONS: The measurement results confirm the enhanced selectivity of the miRNA molecules by using CNFs with SPEs and the developed biosensory system could be used to detect the specific RNA molecules.
