Background: The novel coronavirus pandemic has not only affected people's health. The pandemic has also affected their social life and work. For all the reasons mentioned, international trade has suffered and is still in the process of recovery. Objective: Especially in the semiconductor industry, many manufacturers postponed their deliveries to future periods and this triggered the chip crisis. Many hightech industries, including the automotive industry, were deeply affected by the consequences of the crisis, with factories halting or slowing down production. despite the shortage of chip stocks, Nuvoton has a large amount of Microcontroller Units (MCUs), but due to the shortage of resources, education and libraries, software developers have not been able to integrate their products in a limited time. Methods: In this paper, the Nuvoton Education Board has presented 20 common examples for embedded software developers and beginners. results: The PCB is designed considering all modules connected to separate General Purpose Input Output (GPIO) pins to make multiple module examples without changing the peripherals and pin configuration of the MCU. Clock configuration has been simplified and unnecessary details have been meticulously removed to make the examples easily understandable. Nuvoton NuMaker M263KI V1.3 was added on the designed PCB. Conclusion: The PCB contains almost all the necessary electronics to learn embedded software and use Nuvoton MCUs in industrial projects. The board is supported with user interfaces and printed documentation. The codes are explained with command lines to teach users even small details. A patent application has been filed for the proposed education board. © 2024 Bentham Science Publishers.

This paper describes an anthropomorphic robot hand and its experiments. The robot Hand is a very complicated system composed of a large number of joints. Also, there are limitations of size and weight in the development of the robot hand. Because of these reasons, to manufacture an useful robot hand is a difficult work. Our final goal is a development of a robot hand for practical use in wide service robot application. Firstly, we define several requirements of a robot hand in the sense of structure and function. Although it is difficult to satisfy all of the requirements, we try to develop a robot hand including those. The developed robot hand has 4 full-actuated fingers with total 16 joints. By using of dC motor and spur gears as an actuator unit, the size, weight and cost of the robot hand becomes reasonable. A control of finger is conducted with only geometrical information of fingers without any force sensing. In order to verify performance of the hand, various results of experiments, grasping of unknown rigid and non-rigid object, are presented. In addition, experimental results of grasping under disturbances are also presented.

Fused Filament Fabrication (FFF) is an additive manufacturing process based on Material Extrusion (MEX) of polymeric filament. This manufacturing technology is commonly used for personalized production applications and prototyping, allowing to obtain customized parts with complex geometries at a low cost. However, this production technique has its limitations regarding dimensional accuracy and surface roughness of the final parts. To overcome these limitations, finish milling is considered to be a promising technique as it is widely used for metallic parts. Yet, the specific thermal properties of polymers such as low thermal conductivity and low melting temperature are adding a challenge in the determination of optimal cutting conditions. In this context, the use of cutting fluid could be the key to keep the material from melting during milling. Therefore, this paper proposes to compare the impact of using a compressed air flow to dry conditions on the cutting forces and the surface quality obtained on 3d-printed polylactide (PLA) parts. The qualification test of the tool-material couple standard (NF E 66-520-6) will be used as a guideline to determine the relevance of cutting fluid use for cutting conditions varying around an operating point. Moreover, simulated cutting forces using a mechanistic model will be compared to experimental data to evaluate the applicability of the model.

Modified cyclodextrins (Cds) are cyclic oligosaccharides with many applications in drug delivery, catalysis, and as active pharmaceutical ingredients. In general, they exist as distributions of structurally diverse molecules rather than single-isomer compounds. Their performance depends on the number of glucopyranose units (GPUs), and the type, number, and position of chemical substitutions in their hydroxyl groups. Effectively targeting individual species within these distributions is essential for optimizing Cds for specific applications. Computational techniques can generate large datasets to AI-driven structural optimization, but the absence of a standardized nomenclature system for modified Cds presents a major barrier to progress in this direction. This lack of consensus limits effective communication, data sharing, automation, and collaboration. To address this, a clear and extensible nomenclature for modified Cds is proposed. In this framework, GPUs are treated like amino-acid residues, with unsubstituted GPUs as reference building-blocks and substituted ones considered as mutations. This approach precisely defines substitution types and patterns, resolves cyclic permutation ambiguities, and offers versatility for both simple and complex modifications, including chiral center alterations and covalently linked Cd oligomers. By introducing this standardized nomenclature, we aim to enhance molecular design, improve reproducibility, and streamline both experimental and computational research in the Cd field. © 2025, The Authors.

Backhaul wireless networks are of primary importance in the architecture of 5G telecommunication systems and they have gone through a huge increment in capacity during past years, offering the possibility to reach a data rate greater than 10 Gbps. The aim of this paper is to explore the potentiality of a High-Power Amplifier module (HP A) for backhauling, and in particular the system for long-reach E-band radio in link aggregation configuration. The HP A, by exploiting the excellent results obtained by a 5-stage E-band GaN/SiC MMIC Power Amplifier, reaches a saturated output power of 34 dBm allowing the deployment of an E-band radio link with a hop-length of 10 km and a maximum throughput of 10 Gbps. © 2022 European Microwave Association (EuMA).

The effects of a large number of sintering aids for the densification of magnesia were examined. Al 2 O 3 , BaO, Fe 2 O 3 , P 2 O 5 , SiO 2 , TiO 2 , Y 2 O 3 and ZrO 2 are effective for the sintering of CVd-MgO powders at low doping levels. The effects of TiO 2 and ZrO 2 are significant. Heavy doping is harmful for densification. The eight oxides above are also effective for the sintering of seawater MgO, but the degree of effectiveness is smaller than for CVd-MgO. In the doping of BaO, P 2 O 5 , SiO 2 and TiO 2 , which form eutectic liquids with MgO below 1600°C, there is an optimum firing temperature for densification. Vickers hardness of doped MgO is proportional to the relative density and is unaffected by doping. Corrosion resistance of MgO ceramics for liquid PbO is also unaffected by dopants, except for P 2 O 5 .

Molecular recognition of beta-ribofuranosides by synthetic polypyridine-macrocyclic receptors

JOUrNAL OF THE AMErICAN CHEMICAL SOCIETY 1995年第50期117卷 12416-12425页

作者： Inouye, M Miyake, T Furusyo, M Nakazumi, H Department of Applied Materials Science University of Osaka Prefecture Sakai Osaka 593 Japan Systems and Electronics R&D Center Sumitomo Electric Industry Co. Konohana Osaka 554 Japan

Artificial ribofuranoside receptors were designed and synthesized. The design of the polypyridine-macrocyclic receptors was based on the multipoint hydrogen bond complementarity between the receptors and methyl beta-d-ribofuranoside. The binding affinity of the receptors for the ribofuranoside in CdCl3 was very high (up to K-a = 5.2 x 10(3) M(-1)), so that even native ribose was extracted by them into such nonpolar solvents. Selective extraction of ribose by the receptors\was observed: the extractabilities, or affinities to the receptors of various pentoses and hexoses decreased in the following order: ribose > deoxyribose congruent to lxyose congruent to xylose > fructose > arabinose > glucose congruent to mannose congruent to galactose. The selectivity is governed by the OH direction and the whole size of the sugars as well as their shapes. Furthermore, fluorescence emission of the receptors was largely enhanced in the presence of methyl beta-d-ribofuranoside or ribose, and the degree for the fluorescence enhancement by the addition of various sugars was almost compatible with that of the extractabilities. The polypyridine-macrocycles represent rationally designed multifunctional artificial receptors for ribofuranosides.

Toward the radiation shielding applications, this study produced and tested nanocomposite materials from the attapulgite clay, biochar, and nano-nickel combination at varied concentrations of X = 15.0 %, 30.0 %, and 45.0 %, for the abbreviation A40BXNi(60-X). Fourier transform infrared (FT-Ir), X-ray fluorescence (XrF), and raman microscopy described pristine Attapulgite, biochar, and nano-nickel. In the photon energy range of 0.015: 15 MeV, their radiation shielding properties were determined using Monte-Carlo simulation code (MCNP) and Phy-X web software. Both of biochar, and nano-nickel increases the gamma and neutron radiation shielding in Attapulgite. The synthetic sample A40B15Ni45 with significant nano-nickel doping has the maximum linear attenuation. On the other hand, the A40B15Ni45 Nano nanocomposite which contain the high content of biochar, was found the highest against the fast neutrons. The synthesized A40BXNi(60-X) nano-composites presents the best gamma and fast neutron radiation shielding capability to be used in the various radiation applications. © 2025 Elsevier Ltd

A lead-free glass series was fabricated according to the chemical formula of (40-x) B2O3+20 TeO2 + (20 + x + y) ZnO + (20 - y) CaO, where x = 0, 2, 4, and 6 mol% and y = 0, 3, 6, and 9 mol%. The role of substitution of ZnO for B2O3 and CaO compounds on the physical and radiation shielding properties of the prepared series was investigated. The density of prepared glasses was examined according to the Archimedes method. The increase in the ZnO across the concentration of 20–35 mol% increases the density of prepared glasses throughout 3.945–4.241 g/cm3. Furthermore, the radiation shielding capacities of the prepared glasses were examined through the experimental measurements using an NaI (Tl) detector and some radioactive sources, including Na-22, Ba-133, Co-60, and Cs-137. The data obtained from the experimental measurements was confirmed using Monte Carlo simulation and XCOM that depend on two various nuclear databases. The experiment, simulation, and XCOM calculations confirmed that the increase in the ZnO concentration throughout 20–35 mol% increases the linear attenuation coefficient throughout 0.352–0.367 cm−1 (at 0.511 MeV), 0.297–0.318 cm−1 (at 0.662 MeV), and 0.210–0.224 cm−1 (at 1.275 MeV), respectively. This increase in the linear attenuation coefficient improves the shielding capacity of prepared glasses, which reach 31.45 % (for the TeZn20 glass), 32.22 % (for the TeZn25 glass), 32.87 % (for the TeZn30 glass), and 33.65 % (for the TeZn35 glass) of the shielding capacity of pure lead at 0.662 MeV. © 2025 Elsevier Ltd
