Colloidal self-assembly into highly ordered binary systems represents a versatile and inexpensive approach to generate well defined surface topographical features with submicron resolution. In addition, the use of surface-functionalized particles where each particle bears a different surface functionality enables the generation of highly resolved surface chemical patterns. Such topographical, a...
We present the design and initial operation of a 96 kV, 40 A Magnetron Injection Gun (MIG) for a 1.5 MW, 110 GHz gyrotron. A critical parameter for the successful application of this electron gun is the uniformity of electron emission. The I-V curve of emission, at a series of temperatures, is measured. Analysis indicates that the work function of the emitter is 1.6 eV with a (total) spread of ...
The lack of water resources in Iran has increased concern about water consumption in the country. The agricultural sector is known as the largest sector of water consumption, and saving in this sector will save significant water resources. One of the solutions for the optimal use of water resources is the use of modern irrigation methods with proper design and implementation. Therefore, the pur...
a novel acrylic acid-functionalized fe3o4 magnetic nanoparticle with a core-shell structure was developed for utilization as a heterogeneous organosuperacid in chemical transformations. the structural, surface, and magnetic characteristics of the nanosized catalyst were investigated by various techniques such as transmission electron microscopy (tem), thermogravimetric analysis (tga), and ft-ir...
Building upon the observation that newly defined Ellingsen, et al. (2020) concept of c-differential uniformity is not invariant under EA or CCZ-equivalence Hasan (2021), we showed in Stanica and Geary (2021) adding some appropriate linearized monomials increases inverse function, significantly, for c. We continue investigation here. First, by analyzing involved equations, find bounds Gold funct...
due to the scarcity of water resources, the need for sustainable development of drip irrigation tape is essential in iran. a number of drip irrigation tape systems used in sugar beet fields of isfahan and chahar mahal va bakhtiari provinces were evaluated and were compared with furrow irrigation methods in two consecutive years. the actual water use efficiency (wuesy, wuewsy) in lower quarter, ...
