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...

Magnetothermal Properties of Triethylene Glycol-Coated Cobalt-Zinc-Ferrite Nanoparticles for Magnetic Hyperthermia Applications

Cobalt zinc ferrite (Co$_{0.6}$Zn$_{0.4}$Fe$_2$O) nanoparticles were synthesized using a one-step hydrothermal method. Triethylene glycol (TREG) was used as a biocompatible coating material. The TREG-coated nanoparticles were spherical, with an average diameter of 9.82 nm. The Fourier-transform infrared spectra confirmed the presence of a TREG-coating on the surfaces of the nanoparticles. The particles had a saturation magnetization of 84 emu/g and a coercivity of 32 Oe. The heating capability of the particles was evaluated using an induction system, and the heating curves for aqueous samples with various particle concentrations were obtained. An alternating magnetic field with an amplitude of 4.5 kA/m and a frequency of 216 kHz was applied to the samples. The optimal particle concentration in water for achieving the hyperthermia target temperature of 42 $^\circ$C was 4.58 mg/mL. The specific absorption rate ($SAR$) of the 2-mg/mL sample was 83 W/g. The linear relationship between the $SAR$ and the square of the field strength was confirmed for a representative 10-mg/mL sample. These findings show that TREG-coated particles are suitable for magnetic hyperthermia applications owing to their superparamagnetic properties and high $SAR$ values.

Over the past decade, additive manufacturing and three-dimensional (3D) printing have had a profound impact on manufacturing. With the emergence of affordable 3D printers, rapid prototyping has been quite accessible to researchers in academic and industrial laboratories. As a consequence, the number of laboratory instruments that have been assembled with 3D printed parts has risen. We present an atomic force microscope (AFM) constructed with as many 3D printed parts as the design would permit. Due to its simplicity, the proposed AFM is suitable for assembly by undergraduate students in a project-based laboratory course setting. The images of compact disc (CD) data tracks and standard samples obtained using the proposed low-cost AFM effectively demonstrate its nanoscale imaging capability.
