Abstract
GaN substrates were directly bonded with Si substrates by wet treatments using H2SO4/H2O2 and NH3/H2O2 mixtures. Under the optimized condition, the tensile strength reached 7.36 MPa, and a part of the Si substrate was fractured within the bulk instead of the bonding interface. There is an amorphous intermediate layer with a thickness of 1.7 nm, which mainly consists of Si oxides, at the bonding interface. It is remarkable that wafer-scale GaN/Si integration was successfully achieved by using common cleaning methods. It is believed that the proposed direct bonding technique would contribute to future heterogeneous integration because the GaN and Si substrates can be bonded through the atomically thin intermediate layer without vacuum processes.
Direct observation of porous coordination polymer surfaces by atomic force microscopy
Authors: Hosono Nobuhiko , Kitagawa Susumu 
Published: February 2022

Abstract
Flexible porous coordination polymers (PCPs) and metal–organic frameworks (MOFs) have attracted significant attention as emerging nanoporous materials because their responsive functions have many promising applications in molecular recognition systems and gas storage/separation applications. Flexible PCP/MOFs undergo dynamic structural transformations in response to guest accommodation into the nanopores; here, the outermost surfaces of the PCP/MOFs play a key role in their porous functions. However, the surface structures and behavior in response to external environmental changes are largely unknown due to the limitations of observation techniques. This review provides a brief overview of the surface chemistry and progress of in situ imaging technology as a new tool for the direct visualization of dynamic PCP/MOF surfaces.

The technology of vibrocasting high-quality refractories from granular masses of different chemical composition, size, configuration and weight of products, in particular crucibles for induction melting of heat-resistant alloys was developed and introduced by JSC “URIR named after A. S. Berezhnoy”. According to the developed technology, mullite-alumina zircon-containing crucibles contain ZrO2 ~ 8 %, zirconia-containing crucibles — ~ 17 %, alumina zircon-containing crucibles — ~ 8 %, ~ 8—10 % and ~ 25 %, have open porosity < 20 %, cold crushing strength depending on the used raw materials and firing temperature within ~ 50—230 N/mm2, thermal shock resistance> 20 thermal cycles (1300 °C — water).
The article studies the effect of ZrO2 and SiO2 additives type introduced with zircon or zirconia in combination with a silica-containing additive on the main properties of vibrocasting samples after firing at 1580 °C.
As a result of the studies the high alumina samples with 10 % ZrO2, introduced by zircon or zirconia powder, were produced, which are characterized by apparent density of 3.12 and 3.08 g/cm3, open porosity of 14.4 and 15.5 %, cold crushing strength 145 and 210 N/mm2, thermal shock resistance > 20 thermal cycles and 6 thermal cycles (1300 °C — water) respectively. That is, with practically the same chemical composition, samples with zircon have better indicators of apparent density and especially thermal shock resistance than samples with zirconia in combination with silica. The high thermal shock resistance of samples with zircon can be explained by a nature of the pores which long irregular in configuration and connected to each and, as well as microfractured structure due to the decomposition of zircon and the formation of microcrystalline monoclinic zirconia while in the structure of the samples, which included zirconia powder and silica and a mixture of joint grinding of alumina and a silica-containing additive, the pores are predominantly round isolated. Considering also that zircon is a domestic material and is cheaper than imported ZrO2, it is more expedient to use zircon for crucibles.

Thermal insulation and safety of cement rotary kilns is ensured by the use of modern and reliable refractory materials with a set of specified performance characteristics. The MgO—Al2O3—FeO—ТіО2 system is a physicochemical basis for the development of compositions of periclase-spinel refractories for lining rotary kilns of cement production.
Since periclase-spinel refractories obtained on the basis of the MgO— Al2O3—FeO—ТіО2 system are operated at elevated temperatures, in this article, the calculations of temperatures and compositions of eutectics of binary, triple and quadruple sections of the system are carried out in order to predict the appearance of a melt in the corresponding materials, and to develop technological solutions for a rational amount of melt during sintering and as a seed for a set of coatings.
Analysis of temperatures and compositions of eutectics of multicomponent sections MgO—FeO—Mg2TiO4—MgAl2O4, FeAl2O4—Mg2TiO4—FeO—Fe2TiO4, FeAl2O4—Mg2TiO4—MgAl2O4—FeO and FeAl2O4—MgTiO3—MgAl2O4—Al2O3 systems MgO—Al2O3—FeO—ТіО2 confirms the possibility of synthesis of periclase-spinel refractories with high performance in this system and provides the necessary technological information for targeted control of the relationship “composition—structure—properties” during their production.

In the article, the creation of electrically conductive composite ceramics based on facing tiles with the addition of SiC with specified electrodynamics’ characteristics was considered.
To obtain a press powder, the raw materials in a predetermined amount were weighed, 10, 20 and 30 % silicon carbide were added and subjected to wet grinding in a ball mill. The resulting slip was dried in a drying oven and passed through a № 05 sieve. The finished press powder for facing ceramics with SiC, moistened to 8 %, was weighed and poured into a mold for pressing, the pressure force was 18—20 MPa. The resulting green was dried in a drying oven. The semi-finished product was burned in a sillite furnace at a firing temperature of 1120—1140 °C with a holding at a maximum temperature of 5—10 minutes. The chemical composition of obtained press powder and the technological scheme for obtaining samples were presented.
The obtained data shown that the best sample was facing ceramics with 30 % SiC, which had the following properties: water absorption — 5.9 %, open porosity — 12.5 %, apparent density — 2.13 g/cm2, resistivity — 0.43 ⋅10-6 Ohm ⋅m. The obtained X-ray diffraction pattern indicated the presence of silicon carbide in the sample after firing, which was confirmed by the data on the study of specific volumetric resistance of the studied ceramics and the obtained practical results.

Published: February 2022

A time deposit is one of the major sources of liquidity of the commercial bank to maintain money supply to the demand of business and household sector. In this context, an interesting query is the determinants of time deposit. This paper measures the determinants of time deposit in the commercial banks of Nepal based on 15 years’ time series data sets from 2000-01 to 2017-18 of the sample commercial banks published by the central bank of Nepal. Using descriptive statistics and multiple regression models as the analytical tools, the paper has found a fluctuating trend of liquidity in the commercial banks but the inclining trend of external and internal variables including GDP, Deposit, Capital, Size of Bank, remittance, and public debt. In this trend, the liquidity of the commercial banks depends significantly on time deposits and remittance inflow. Besides, the positive trend of time deposit from 1994-95 to 2017-18 has caused the positive trend of total deposit from 1994-95 to 2017-18. Additionally, the paper has found that GDP per capita, US exchange rate, interest rate, and the branch of the bank are positively and significant determinants to the time deposit of the commercial bank but the inflation rate is negatively and determinant with significance. The internal variables are more determinants than the external variables to the time deposits. It is clear that time deposit is a reliable and long-term source to main the bank liquidity of the commercial bank for their financial stability and performance depends on more the internal variables than the external variables. Therefore, the commercial bank should reform as mentioned in the monetary policy and money market dynamics to improve the competitiveness and smartness of bank policy including interest rate policy and branch of the commercial banks for effective mobilization of the scattered small resources all over the country for the higher rate of capital formation, investment, and economic growth.

Resource Allocation for Joint Interference Management and Security Enhancement in Cellular-Connected Internet-of-Drones Networks
Authors: HASSAN MD ZOHEB , Kaddoum Georges , Akhrif Ouassima 
Published: February 2022

<p>Internet-of-drones (IoD) systems require enhanced data transmission security and efficient interference management to accommodate the rapidly growing drone-based and rate-intensive applications. This paper develops a novel resource allocation scheme to jointly manage interference and enhance the physical layer security of cellular-connected IoD networks in the presence of a multi-band eavesdropping drone. Our envisioned cellular-connected IoD network has multiple full-duplex cellular base stations (CBSs), where each CBS reserves an orthogonal cellular radio resource block (RRB) for the aerial communication links. To efficiently utilize the cellular RRBs, each CBS is connected to a cluster of data transmitting drones using uplink non-orthogonal multiple access (NOMA) scheme. In addition, all the CBSs simultaneously transmit artificial noise signals to weaken the eavesdropper links. A joint optimization problem, considering the transmit power allocation and clustering of the legitimate drones, and the jamming power allocation of the CBSs, is formulated to maximize the worst-case average sum-secrecy-rate of the network. The joint optimization problem is decomposed into drone-clustering and power allocation sub-problems to obtain an efficient solution. A multi-agent reinforcement-learning framework is devised to solve the drone-clustering sub-problem. Meanwhile, the transmit and jamming power allocation sub-problem is solved by employing fractional programming, successive convex approximation, and alternating optimization techniques. By iteratively solving these two sub-problems, a convergent resource allocation algorithm, namely, security and interference management with reinforcement-learning and NOMA (SIREN), is proposed. The superiority of SIREN over several benchmark schemes is verified via extensive simulations. </p>
