“…Because of the low cost, ready availability in various forms, chemical inertness, mechanical properties and high specific proton density of polyethylene (PE) materials, many emerging applications of PE have been envisioned. For example, PE microspheres have been employed as core materials for fabricating hollow alumina microspheres and non‐porous silica ultramicrospheres for HPLC column packing 1, 2. PE fibers can serve as filtration materials, absorber materials of heavy particle irradiation for space exploration or precursors of carbon fibers in the presence of a catalyst 3–7.…”

Low density polyethylene (LDPE) was prepared into micro‐ or submicro‐spheres or nanofibers via melt blending or extrusion of cellulose acetate butyrate (CAB)/LDPE immiscible blends and subsequent removal of the CAB matrix. The sizes of the PE spheres or fibers can be successfully controlled by varying the composition ratio and modifying the interfacial properties of the blends. The surface structures of LDPE micro‐ or submicro‐spheres and nanofibers were analyzed using SEM and FTIR‐ATR spectroscopy. In addition, the crystalline structures of the LDPE nanofibers were characterized.magnified image

“…Because the OPAL opacity has a prominent peak at log T (K) ∼ 5.2 owing to iron ionization (Iglesias & Rogers 1996), the optically thick winds are accelerated around this temperature region, i.e., deep inside the photosphere. The occurrence condition of winds was examined first by Kato (1985) for the old opacities, and then by Kato & Hachisu (2009) and Kato et al (2013) for the OPAL opacities (Iglesias & Rogers 1996). These works clarified that WDs do not emit optically-thick winds in the following cases.…”

“…These condition led us to search nova (thermonuclear runaway event) solutions for no-mass-ejection (e.g. Kato 1985;Kato & Hachisu 2009). They are periodically variable supersoft X-ray sources (e.g., Hachisu et al 2016).…”

ASASSN-16oh is a peculiar transient supersoft X-ray source without a mass ejection signature in the field of the Small Magellanic Cloud. Maccarone et al. (2019) concluded that ASASSN-16oh is the first dwarf nova with supersoft X-ray that originated from an equatorial accretion belt on a white dwarf (WD). Hillman et al. (2019) proposed a thermonuclear runaway model that both the X-rays and V /I photons are emitted from the hot WD. We calculated the same parameter models as Hillman et al.'s and found that they manipulated on/off the mass-accretion, and their best fit V light curves are 6 mag fainter, and decay about 10 times slower, than that of ASASSN-16oh. We propose a nova model induced by a high rate of mass-accretion during a dwarf nova outburst, i.e., the X-rays originate from the surface of the hydrogen-burning WD whereas the V /I photons are from the irradiated disk. Our model explains the main observational properties of ASASSN-16oh. We also obtained thermonuclear runaway models with no mass ejection for a wide range of parameters of the WD mass and massaccretion rates including both natural and forced novae in low-metal environments of Z = 0.001 and Z = 0.0001. They are a new type of periodic supersoft X-ray sources with no mass ejection, and also a bright transient in V /I bands if they have a large disk. We suggest that such objects are candidates of Type Ia supernova progenitors because its mass is increasing at a very high efficiency (∼ 100%).

Inorganic microballoons composed of metal-silicate shell were prepared by ion exchange between internal Na+ and external metal cation through liquid surfactant membrane. The effects of metal species and salts concentration on the state of microballoons were examined for a series of alkaline earth and transition metals. The mechanism of balloons formation was discussed based on the ion releasing behavior and the composition of particles.
