Bilayer Formation

We propose a two-dimensional BP3crystal with a very high electron mobility of 4.6 × 104cm2V−1s−1. Bilayer formation, specifically stacking pattern AA, results in an even higher electron mobility of ∼3.7 × 105cm2V−1s−1, which is ∼2500 times larger than that of an α phosphorene bilayer.

This study aims to analyze the critical thinking skills of P21 students in solving Arithmetic Two Dimensional problems through the application of Guided Discovery Learning. GDL is a learning process that occurs when students are not presented  with material in final form but learners are expected to organize their own material with guidance from educators if needed. Implementation of GDL in learning process is expected to improve students' thinking ability, especially critical thinking ability version P21. According to P21, in the 21st century, every individual is required to have 4C's skills in order to compete globally and one of 4C's skills is critical thinking. By having these skills, learners are expected to achieve success in life and work. The subjects of this study are discrete mathematics class students, as many as 64 students. Research steps are by providing initial knowledge of Two Dimensional Arithmetic materials through GDL method and Student Worksheet (LKM) then at the end of student learning work on Test Mastery of Teaching Materials (TPBA). The test results are then analyzed using the P21 critical thinking indicator that is reasoned effectively, using a system of thinking, making judgments and decisions. From the analysis result of Teaching Material Mastery Test obtained data about critical thinking level of students, in class A there are 25 students being in very high category (level 4), 10 students are in high category (level 3) and 9 students are in medium category (level 2). While in class C there are 22 students being in very high category (level 4), 4 students are in high category (level 3) and 4 students are in medium category (level 2). The study also produced a two dimensional arithmetic monograph. From the results of this study can be concluded that the application of GDL has a positive effect in developing students' critical thinking skills in solving two-dimensional arithmetic problems.

Direct numerical simulations and linear stability analysis are carried out to study mixed convection in a horizontal duct with constant-rate heating applied at the bottom and an imposed transverse horizontal magnetic field. A two-dimensional approximation corresponding to the asymptotic limit of a very strong magnetic field effect is validated and applied, together with full three-dimensional analysis, to investigate the flow's behaviour in the previously unexplored range of control parameters corresponding to typical conditions of a liquid metal blanket of a nuclear fusion reactor (Hartmann numbers up to $10^4$ and Grashof numbers up to $10^{10}$ ). It is found that the instability to quasi-two-dimensional rolls parallel to the magnetic field discovered at smaller Hartmann and Grashof numbers in earlier studies also occurs in this parameter range. Transport of the rolls by the mean flow leads to magnetoconvective temperature fluctuations of exceptionally high amplitudes. It is also demonstrated that quasi-two-dimensional structure of flows at very high Hartmann numbers does not guarantee accuracy of the classical two-dimensional approximation. The accuracy deteriorates at the highest Grashof numbers considered in the study.
