Dear Editor,Since the COVID-19 demonstrated a remarkable transmission speed and a high mortality risk,COVID-19 is currently declared as a pandemic by the World Health *** is the first time that the WHO has declared a pandemic since H1N1 in *** of 6 September 2020,the total number of COVID-19 patients is 26,763,217(876,616 deaths),and it continues to rise(https://***/).In spite of the urgent demand for the vaccines and therapeutics,global efforts are primarily focused on the utilization of the existing anti-viral drugs,such as remdesivir,hydroxychloroquine,and dexamethasone,to relieve the symptoms due to the limited development of renovative therapeutics.

Transferring single-crystalline(SC)membranes to flexible substrates has been increasingly studied,enabling emerging functionality and enhanced performance of various devices.A commonly used support-assisted transfer process inevitably leaves dirty residue on material surfaces,limiting the further development of surface-related ***,we scale down the thickness of flexible SC SrRuO_(3)(SRO)membranes to 15 nm with a clean surface area of 2.5×2.5 mm^(2).This is accomplished by making the polyethylene terephthalate(PET)substrate surface hydrophilic via oxygen plasma treatment,thereby reducing the surface *** ultrathin,clean,wide,and flexible SC SRO membranes guarantee a high transmittance of up to 60%,a low resistivity of 10^(−4)−10^(−3)Ωcm at room temperature,and band ferromagnetism below 150 K with a high magnetic moment of~0.5μB/Ru at 10 *** SC-level properties of our SRO membranes imply their potential use in state-of-the-art platforms for next-generation electronics and energy devices.

Nondestructive Skeletal Imaging of Hyla suweonensis Using Micro-Computed Tomography

引用

Asian Herpetological Research 2017年第4期18卷 235-243页

作者： Eunbin kim Hacheol SUNG Donghyun LEE Geunjoong kim dongha NAM Etmgsam kim School of Biological Sciences and Biotechnology Chonnam National University 77 Yongbong-ro Bukgu Gwangju 61186 South Korea2 u 61186 South Korea

We successfully obtained 3D skeletal images of Hyla suweonensis, employing a nondestructive method by applying appropriate anesthesia and limiting the radiation dose. H. suweonensis is a tree frog endemic to Korea and is on the list of endangered species. Previous studies have employed caliper-based measurements and two-dimensional （2D） X-ray imaging for anatomical analyses of the skeletal system or bone types of H. suweonensis. In this work we reconstructed three-dimensional （3D） skeletal images of H. suweonensis, utilizing a nondestructive micro-computed tomography （micro-CT） with a short scan and low radiation dose （i.e. 4 min and 0.16 Gy）. Importantly, our approach can be applied to the imaging of 3D skeletal systems of other endangered frog species, allowing both versatile and high contrast images of anatomical structures without causing any significant damages to the living animal.
