Aims and Scope

The origin of New Physics: Sae Mulli (NPSM, ISO abbreviation: New Phys.: Sae Mulli.): Sae Mulli (새물리 in Korean characters means ‘new physics’) is the oldest Korean pure scientific journal. It was first published in 1961 just after the Korean War by the Korean Physical Society (KPS). The primary mission of Sae Mulli was to start building up Korean physics research community from almost nothing and in fact Sae Mulli had made tremendous contributions to the Korean science community. Through a peer-review system, Sae Mulli had continued elevating the level of scientific researches, consequently becoming a cornerstone of the economic miracle of Korea...

Nanoporosity is an advantageous property for the polymeric membrane films in fuel cells, filters, and drug delivery systems, in which interconnected pores within the material facilitate transport of small molecules across the membrane. Here, we examined the effect of a DC electric field on the pore structure and oxygen transport of films formed by bicontinuous microemulsion polymerization (BµEP) of 2-hydroxyethyl methacrylate and methyl methacrylate in water containing a cationic surfactant, and compared with those of samples polymerized without an applied electric field. Membranes polymerized through BµEP under an applied electric field that showed 50-130\% increase in oxygen transmissibility demonstrated more elongated pore channels in 3D nanoscopic image as well as smaller standard deviations in pore size distribution than those of membranes that exhibited a decrease in oxygen transmissibility. The results suggest the potential of this preparative technique for controlling pore connectivity in a nanostructured membrane system.

The Dependence of the characteristics of MgZnO thin films deposited by using a RF sputtering system on the deposition power were investigated. A Mg$_{0.3}$Zn$_{0.7}$O target was used to deposit thin films at powers of 150 W, 200 W, 250 W, and 300 W. While the hexagonal (002) orientation in the X-ray diffractometry (XRD) patterns increases as the deposition power increases, the MgO (200) peak begins to appear and the MgZnO (002) peak sharply decreases at 300 W. X-ray photoelectron spectroscopy (XPS) measurements showed the binding energy of the Zn2$_{p3}$ peak to be is close to that of pure ZnO, which means an the improvement in the ZnO crystallinity with increasing deposition power. However, Hall measurements show that as the crystallinity improves, the oxygen vacancies, acting as electron donors, are reduced, as are the and electron concentration and mobility and the electrical conductivity.
