1.0 overview it seems that grammar plays a crucial role in the area of second and foreign language learning and widely has been acknowledged in grammar research. in other words, teaching grammar is an issue which has attracted much attention to itself, and a lot of teachers argue about the existence of grammar in language teaching and learning. this issue will remind us a famous sentence f...
Halide perovskites solar cells (PSCs) are making true on past promises, having reached power conversion efficiencies (PCEs) of 25.7% and long lifespans (>3000 h). Although stability has become the focus research efforts, a significant number researchers still dedicated to further increasing cell efficiency. To push PCE any higher however, every element must be controlled optimized. In context r...
Recent work has shown that small additions of chemical modifiers can cause major structural rearrangements on Ag, Cu (l-3), and Pt (4) surfaces. The first purpose of this letter is to explain how these electronically driven geometrical changes arise. Second, we suggest that in catalysis, the role of electron donor/acceptors may often be an indirect one, namely to cause such geometrical changes....
This paper presents a voltage mode universal filter using two multi-output operational transconductance amplifier (OTA). Proposed multi-input single output universal filter employs two capacitors only and realizes all the standard second order filtering functions from same configuration. Filter parameters namely pole frequency and quality factor can be tuned independently without affecting each...
