Effect of the length of silicon nano-dot/wire on band gap by Hassan, Walid M.I.

“…We will report on the role of the length of silicon nanowire (SNW) in determining the band gap of a structure. We find that the band gap decreases with SNW length for the same diameter and approaches the band gap for an ideal infinitely long SNW. …”

Emerging clay-aryl-gold nanohybrids for efficient electrocatalytic proton reduction by Jlassi, Khouloud

“…Both nanohybrids showed efficient electrochemical activity for HER in acidic condition (0.1 M H2SO4) with high current density up to −25 mA.cm−2 at −1 V and 0.148 mV onset. Negligible decreasing in current density and slight shift in onset was observed after 1000 cycles. …”

Electrochemical oxidation of ammonia (NH4+/NH3) ON synthesized nickel-cobalt oxide catalyst by Almomani F.

“…The reported Pgen were 0.55, 0.85, 1.1 and 0.0.93 mW/cm2 for Ni–C, Co10/Ni–C, Co20/Ni–C and Co40/Ni–C. A concentration of Co higher than 40% decreased cell potential (Vcell) and reduced the percentage removal of ammonia (%REAmm). …”

Simulation and experimental study of underwater dissimilar friction-stir welding between aluminium and steel by Eyvazian, Arameh

“…Theeffects of processing parameters on the formation of intermetallic compounds (IMCs) atthe Al/St interface, microstructural characteristics, and mechanical property of dissimilarweldments were studied and addressed. By decreasing tool rotational speed (w), increas-ing traverse velocity (v), and employing cooling medium, peak temperature continuouslyreduced (down to ?…”

Long-Distance Vowel-to-Vowel Coarticulation in Arabic: Influences of Intervening Consonant Pharyngealization and Length by Ahmed, Sarah

“…Speakers of Egyptian Arabic were recorded saying sentences containing nonsense sequences of the form /baɁabaCV:/, where C was chosen from {/t/, /tˤ/, /t:/, /tˤ:/} and V was a long vowel /i:/, /a:/ or /u:/. Analysis of the first and second formants of the recorded vowels revealed that (a) vowel-to-vowel coarticulatory effects could sometimes extend to a distance of three vowels before the context vowel; (b) the consonant-to-vowel effects associated with pharyngealization were consistently seen at similar distances, while also decreasing in magnitude at greater distances from the triggering consonant; and (c) effects related to intervening consonant length were idiosyncratic, and in particular did not lead to consistent blocking of vowel-to-vowel effects. …”
