TL;DR: In this paper , a heterogeneous graphene quantum dot (GQD)/ZnO composite was proposed as a photocatalyst for degrading antibiotics by using co-precipitation and thermal carbonization processes.
Abstract: Industrial and medical wastewater treatment has been the focus of significant research and development in recent years. Especially untreated antibiotics commonly found within the wastewater generated by the hospitals or/and manufacturers have caused serious environmental concerns. In this work, we proposed a heterogeneous graphene quantum dot (GQD)/ZnO composite as a photocatalyst for degrading antibiotics by using co-precipitation and thermal carbonization processes. The introduction of N-GQDs efficiently facilitates the photocatalytic activity and reaction rate. Indeed, the N-functionalized GQDs, including pyrrolic/pyridinic N and graphitic N, can accelerate the charge transfer rate in the heterostructures. Optimizing the composition of GQD/ZnO catalyst, ultra-high removal ratio (∼100%) and significantly improved rate constant (i.e., 1.74 times higher compared to pristine ZnO) was achieved. In the binary catalyst, the presence of N-GQDs enhances the absorption in visible-light region and increases the photo-induced charge carrier, resulting in an elevated photocatalytic activity. This finding reveals that the GQD/ZnO composite structure demonstrated in this work can be employed as an in-expensive photocatalyst for degrading metronidazole (MNZ) in liquid phase under the UV-light irradiation.

TL;DR: In this article , the effect of al-doping into the TNO crystal structure, physico-chemical properties and electrochemical performance was systematically analyzed for Li-ion rechargeable batteries anode.
Abstract: Titanium and Niobium-based oxides are served as safety and more stable intercalation type potential anode materials for Li-ion batteries. In this work, we synthesize pristine titanium niobate (TiNb2O7, as denoted TNO) and novel aluminium doped TNO (Al-TNO) mesoporous materials via a facile solvothermal method for lithium-ion rechargeable batteries anode. The effect of Al-doping into the TNO crystal structure, physico-chemical properties and electrochemical performance are systematically analyzed. The optimized Ti0.95Al0.05Nb2O7 sample exhibits higher Li-ion storage performance. The observed initial specific capacity is 283 mAh g−1 at 0.1 C and sustains 155 mAh g−1 after 250 cycles at a current rate of 5 C. Whereas, the pristine TiNb2O7 exhibits initial discharge capacity of 278 mAh g−1 at 0.1 C and maintains 118 mAh g−1 after 250 cycles at 5 C. The resultant Al-TNO leads to enhance the conductivity and facilitate the fast Li-ion kinetics behaviours. Therefore, Al-doped TNO electrode cell revealed a higher electrochemical performance than that of pristine TNO electrode. Hence, this work provides an effective manner to improve the high-performance anode materials for Li-ion high-energy storage applications.

TL;DR: In this paper, a study on the selection of photoinitiators used in DLP-AM was conducted, and the authors found that B2/TEOA and TPO exhibit a wider light absorbance range than I2959 and DMPA.
Abstract: Digital light processing additive manufacturing (DLP-AM) technology has received a lot of attention in the field of biomedical engineering due to its high precision and customizability. However, some photoinitiators, as one of the key components in DLP-AM, may present toxicity and limit the application of DLP-AM toward biomedical applications. In order to gain further insights into the correlation between biocompatibility and photoinitiators in photoresins, a study on the selection of photoinitiators used in DLP-AM is conducted. The light absorbance range and cytocompatibility of four photoinitiators, vitamin B2 combined with triethanolamine (B2/TEOA), diphenyl(2,4,6-trimethylbenzoyl)phosphine oxide (TPO), 2-dimethoxy-2-phenylacetophenone (DMPA), and 2-hydroxy-4-(2-hydroxyethoxy)-2-methylpropiophenone (I2959), are characterized. Each photoinitiator is then combined with poly(glycerol sebacate) acrylate (PGSA) and poly(e-caprolactone) diacrylate (PCLDA), to evaluate their miscibility and film formation ability through photopolymerization. The mechanical properties, in vitro and in vivo biocompatibility studies on bulk films are investigated. It is found that B2/TEOA and TPO exhibit a wider light absorbance range than I2959 and DMPA. PGSA films with B2/TEOA (PGSA-B2/TEOA) is capable of sustaining cell proliferation up to 10 days and showing low immune responses after 14 days post implantation, proving its biocompatibility. Although B2/TEOA requires longer photopolymerization time, the mechanical strength of PGSA-B2/TEOA is comparable to PGSA films with TPO and DMPA, and this combination is 3D-printable through DLP-AM at the rate of 100 s per layer. In summary, B2/TEOA is a promising photoinitiator for 3D printing.

TL;DR: In this article , a game-based learning approach was developed to deliver comprehensive conceptual information on SDGs, and a comprehensive sustainable development evaluation questionnaire was developed and optimized using the fuzzy Delphi method to assess the participants' knowledge of and attitudes toward SDGs.
Abstract: To promote the United Nations’ Sustainable Development Goals (SDGs), public awareness of the importance and urgency of sustainable development should be raised by providing relevant education programs. Although game-based learning has been confirmed to be one of the most effective routes to deepen public understanding of the SDGs and sustainable development in general, games for comprehensive sustainable development-based courses have yet to be popularized. Thus, we developed a game-based learning approach that delivers comprehensive conceptual information on SDGs. Based on Kolb’s theory of experiential learning, students understood the relevance of the SDGs by playing a board game designed to simulate the real world, including national and international policies. Furthermore, considering the suspension of in-person learning and shifts to digital instruction caused by the ongoing COVID-19 pandemic, a digital version of the board game was created to compare the effects of digital and non-digital game-based learning. A comprehensive sustainable development evaluation questionnaire was developed and optimized using the fuzzy Delphi method to assess the participants’ knowledge of and attitudes toward the SDGs. Our results reveal that the digital and non-digital board game both improve students’ knowledge and attitude toward sustainable development. However, the digital board game was more effective than the non-digital board game.

TL;DR: In this paper , a paper-based biosensor for quantitative determination of uric acid using electrochemical detection was presented, where the working electrode of the biosensor was modified with graphene oxide (GO) and 5-amino-1,3,4-thiadiazole-2-thiol (ATT) by electropolymerizing ATT on the surface of graphene oxide.
Abstract: Uric acid is the primary end product of human purine metabolism and has been regarded as a key parameter in urine and blood for monitoring physiological conditions. This paper presents a paper-based biosensor for a quantitative determination of uric acid using electrochemical detection. The working electrode of the biosensor is modified with graphene oxide (GO) and 5-amino-1,3,4-thiadiazole-2-thiol (ATT) by electropolymerizing ATT on the surface of graphene oxide. In this study, cyclic voltammetry (CV) measurements required only 200 μL of analyte solution. The experimental results showed that the oxidation peak current increased as the concentration of uric acid become higher and exhibited a linear relationship in the concentration range of 0.1–10 mM, indicating that this proposed biosensor has high sensitivity. In addition, this biosensor has good selectivity to detect uric acid because ATT has a specific binding with it. In human blood and body fluids, nitrites may be the only factor that can interfere with the detection of uric acid using this proposed biosensor. Nevertheless, uric acid can be discriminated from nitrite in the CV measurement due to different oxidation potentials. Thus, this proposed paper-based biosensor is a promising tool for detecting uric acid in biological samples.

TL;DR: A hybrid MCDM approach to evaluate the Vietnamese banking sector's performance under COVID-19 impacts offers useful insights and is applicable to many businesses, proving helpful in dealing with complex criteria problems for stakeholders.
Abstract: As an essential and exciting topic in financial management, MCDM has been widely used in evaluating financial performance to improve the suitability and reliability of financial indicators with respect to the impacts of both qualitative and quantitative information. This chapter aims to present a hybrid MCDM approach to evaluate the Vietnamese banking sector's performance under COVID-19 impacts. The proposed method utilizes The Criteria Importance Through Intercriteria Correlation (CRITIC) technique to determine objective weights of financial ratios. Decision-Making Trial and Evaluation Laboratory (DEMATEL) method is employed to obtain the cause-effect relationship and the subjective weights based on experts’ judgments. Bank alternatives’ ranking is estimated using the Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) approach. The empirical data of 23 Vietnamese commercial banks gathered from 2019-Q3/2020 is illustrated. The results of this chapter show that the COVID-19 pandemic has significant effects on the quality of assets, the liquidity of banks, and the growth rate. When the economy slows down, banks face the challenge of keeping up with demand and raising additional resources to balance the situation. For better intelligent risk management systems, faster digital transformation is needed for the Vietnamese banking system. Furthermore, the proposed method offers useful insights and is applicable to many businesses, proving helpful in dealing with complex criteria problems for stakeholders.

TL;DR: In this article , the authors presented the topology of a three-phase LLC resonant converter with matrix transformers, and the theoretical analysis and performance of the proposed converter are verified.
Abstract: This study presents the topology of a three-phase LLC resonant converter with matrix transformers. The three-phase LLC resonant converter has the advantages of conventional LLC resonant converters, including zero-voltage switching at the primary side, zero-current switching at the secondary side, high-frequency feasibility, and high efficiency. Moreover, it has additional advantages that differ from conventional LLC, including low output capacitor current ripple, natural current sharing in three resonant currents, and a high power level. As a result of the above mentioned characteristics, LLC topology has been used in many electric vehicle charging systems, server power systems, and other high-power applications. However, as the power level becomes higher and higher, the input voltage is usually too high to reduce conduction loss, and the output current also increases. This situation makes transformer design more difficult. The increasing current means more core and copper loss, and the heat dissipation of the transformer becomes more difficult. Matrix transformer technology can improve this problem directly and simply. By utilizing matrix transformers, which are primary series connected and secondary parallel connected, the primary voltage stress and secondary current stress of the transformers can be reduced, and the output current can be distributed. The analysis of the proposed converter in this study includes a circuit operation introduction, a time-domain analysis, calculation of the transfer ratio curve in the frequency domain, and a loss analysis. The theoretical analysis and performance of the proposed converter are verified. A three-phase LLC resonant converter with matrix transformers prototype is built with a high input voltage of 800-VDC and high output current of 200-A. The output voltage is 100-VDC. The waveform and efficiency data will be shown in the experimental results.
