Gas-Phase Alkali Metal-Assisted MOCVD Growth of 2D Transition Metal Dichalcogenides for Large-Scale Precise Nucleation Control.

Advances in large-area and high-quality 2D transition metal dichalcogenides (TMDCs) growth are essential for semiconductor applications. Here, the gas-phase alkali metal-assisted metal-organic chemical vapor deposition (GAA-MOCVD) of 2D TMDCs is reported. It is determined that sodium propionate (SP) is an ideal gas-phase alkali-metal additive for nucleation control in the MOCVD of 2D TMDCs.

Growth and Interlayer Engineering of 2D Layered Semiconductors for Future Electronics.

Layered materials that do not form a covalent bond in a vertical direction can be prepared in a few atoms to one atom thickness without dangling bonds. This distinctive characteristic of limiting thickness around the sub-nanometer level allowed scientists to explore various physical phenomena in the quantum realm. In addition to the contribution to fundamental science, various applications were proposed.

Performance evaluation of platelet counting of Abbott Alinity hq and Sysmex XN-9000 automated hematology analyzer compared with international reference method.

Introduction: Accurate platelet counting is essential for risk assessment of bleeding and thrombosis. Abbott Alinity hq hematology analyzer was recently introduced, and its performance in platelet counting has yet to be evaluated comprehensively. In this study, we evaluated the performance of the optical platelet counting of Abbott Alinity hq (Alinity-PLT) and the impedance and fluorescent platelet counting of Sysmex XN-9000 (XN-PLT-I and XN-PLT-F) compared with the international reference method.

Effects of core balance training on Cobb angle, isokinetic torque, and balance in unilateral handed athletes.

This study aimed to provide fundamental data of core balance training (CBT) on Cobb angle and isokinetic torque and balance in unilateral exercised athletes. Forty-eight subjects were divided by control group (CON; n=16), non-CBT exercised group in unilateral handed athletes (NEG, n=16), and CBT exercised group in unilateral handed athletes (EG, n=16), respectively. Although the group by time interaction in the Cobb angle and in the isokinetic torque were not significantly changed in the EG, the balance of the EG showed significantly improved.

Distinct frequencies and mutation spectrums of genetic thrombophilia in Korea in comparison with other Asian countries both in patients with thromboembolism and in the general population.

Hereditary natural anticoagulant deficiencies are the major cause of genetic thrombophilia in Asia. Given the growing acknowledgment of the risk of venous thromboembolism in Asian populations, we investigated the frequency and mutation spectrums of natural anticoagulant deficiency in Korea. The group of patients consisted of consecutive patients with venous thromboembolism screened for thrombophilia.

Establishment of reference intervals for von Willebrand factor antigen and eight coagulation factors in a Korean population following the Clinical and Laboratory Standards Institute guidelines.

Establishment of reference intervals for coagulation molecules is important but is costly and sometimes not feasible. Since reference intervals from manufacturers or the literature are mostly out of date or involved Western populations, the authors determined reference intervals for VWF: Ag and eight factors in a Korean population. VWF: Ag, factor VIII (FVIII), FII, FV, FVII, FIX, FX, FXI, and FXII were determined in Korean individuals visiting for routine checkup following the CLSI (Clinical and Laboratory Standards Institute) guidelines.

Severe factor XI deficiency in a Korean woman with a novel missense mutation (Val498Met) and duplication G mutation in exon 13 of the F11 gene.

Hereditary factor XI (FXI) deficiency is a rare bleeding disorder inherited in an autosomal recessive manner. The genetic background of FXI deficiency is the mutations in the F11 gene on the chromosome band 4q35. The prevalence is known to be particularly high in Ashkenazi Jews with well documented recurrent mutations; however, founder mutations in F11 have also been reported in non-Jewish patients.
