In the present work, Pt-Cr2N composite and carbon thin film electrodes were directly deposited on a flexible 304 stainless steel current collector by one-step sputtering technique. The inclusion of platinum (Pt) in chromium nitride (Cr2N) provides significant enhancement electrochemical properties Cr2N. prepared composite-based electrode demonstrates high specific capacitance cyclic life compar...

Abstract Directed energy deposition (DED) was used to produce niobium carbide (NbC)‐reinforced Ti6Al4V (Ti64) metal–matrix‐composite (MMC) structures. The objective improve upon Ti64's wear and oxidation resistance. characterization techniques consisted of scanning electron microscopy (SEM), backscattered (BSE) imaging, energy‐dispersive X‐ray spectroscopy (EDS), diffraction analysis (XRD), the...

Haemophilus ducreyi is the etiologic agent of the sexually transmitted genital ulcer disease chancroid. In both natural and experimental chancroid, H. ducreyi colocalizes with fibrin at the base of the ulcer. Fibrin is obtained by cleavage of the serum glycoprotein fibrinogen (Fg) by thrombin to initiate formation of the blood clot. Fg binding proteins are critical virulence factors in medicall...

This study adopts the Keller’s ARCS (Attention, Relevance, Confidence, and Satisfaction) motivational design framework to develop instructional strategies to integrate educational game learning into formal classroom settings. The experimental instruction lasts 8 weeks and there are 103 students in 6 grader involved. From the result of students’ opinions, motivational instruction strategies deve...
