Ti_(3)C_(2)MXene is an auspicious energy storage material due to its metallic conductivity and layered assembly.However,in the real working condition of electrochemical energy storage with long cycle charging-discharging,a structural collapse is usually caused by the stacking of its layers creating a large attenuation of specific capacitance.Inspired by the superlattice effect of magic angle graphene,we conducted microscopical regulation of rotation mismatch on the Ti_(3)C_(2)lattice;consequently,a hexagonal fewlayered Ti_(3)C_(2)free-standing film constructed with Moiré-superlattices.Such finding not only solves the problem of Ti_(3)C_(2)structural collapse but also dramatically improves the specific capacitance of Ti_(3)C_(2)as a supercapacitor electrode under long cycle charging and discharging.The ultra-stable energy storage of this electrode material in a neutral aqueous electrolyte was realized.Moreover,the formation mechanism of rotating Moirépattern is revealed through microscopy and microanalysis of the produced Moirépattern,assisted with modeling and analyzing the underlying mechanism between the Moirépattern and the rotation angle.Our work provides experimental and theoretical support for future construction of Moiré-superlattice structure for a wide range of MXene phases and is undoubtedly promoting the development of MXene materials in the field of energy storage.

Metal organic frameworks(MOFs) have been considered as compelling precursor for miscellaneous applications. However, their unsatisfied electrocatalytic performance limits their direct application as electrocatalyst. Herein, by incorporating the cobalt-oxide bonds and polyaniline(PANI) with two-dimension zeolitic imidazolate frameworks(ZIFs), a novel bifunctional catalyst(Co-O-ZIF/PANI) for Zn-air battery was designed based on a facile and eco-friendly method. This Co-O-ZIF/PANI with optimized surface adsorption effect and suitable Co^(3+)/Co^(2+)ratio, exhibits eminent electrocatalytic activity toward both oxygen reduction and evolution reaction. The as-assembled liquid ZABs based on Co-O-ZIF/PANI achieves a remarkable maximum power density of 123.1 m W cm^(-2) and low discharge-charge voltage gap of 0.81 V at 5 m A cm^(-2) for over 300 cycles. Operando Raman spectroscopy reveals that the excellent performance origins from the optimized surface chemisorption property of O_(2) and H_(2)O brought by Co–O bonds and PANI. This work provides a novel prospect to develop efficient MOF derived bifunctional electrocatalysts by optimizing surface chemisorption properties.

日益严峻的能源危机及环境污染问题促使人们研发清洁能源转换和存储技术.燃料电池和金属-空气电池因功率密度高、操作方便而成为备受关注的能量转换器件.氧还原反应(ORR)是燃料电池和金属-空气电池中必不可少的关键反应.然而,由于氧还原反应的动力学缓慢,极大地限制了反应的快速进行.Pt基电催化剂虽然表现出良好的ORR活性,但稀缺性和稳定性差的缺点制约了其在燃料电池和金属空气电池领域的大规模商业化应用.单原子催化剂(SACs)由于具有丰富的活性位点和几乎100%的金属利用率而成为电催化研究的热点.SACs的几何构型和电子构型很大程度取决于其独特的原子微环境调制(MEM),包括催化中心的局部配位环境和电子状态.因此,SACs的活性、选择性和稳定性与它们的MEM直接相关.由于传统催化剂缺乏结构的精确解析和可定制性,理解和调控催化位点的MEM对多相催化反应性能的影响仍然具有挑战性和局限性.本文通过两步热解法可控制备N,P双掺杂碳基底负载Zn单原子催化剂(Zn-N_(4)P/C),实现对Zn单原子微环境的原子级调控.实验和理论计算研究表明,N/P配位对Zn单原子催化剂电子结构具有协同调控的作用,从而改变Zn周围的局部电荷分布,降低ORR基元反应的势垒.XPS结果显示,Zn-N_(4)P/C中N和P同时存在,且其Zn的结合能相对ZnN_(4)/C向高结合能方向偏移,表明引入的P与相邻的ZnN_(4)间发生电荷转移,影响了Zn单原子的电子结构.XAS结果表明,ZnN_(4)P/C的结构是由位于第二壳层的P与Zn-N_(4)相连构成,且由于P的电负性更强,导致相邻Zn-N的电子转移到N-P键,Zn-N键的键长变长,Zn的价态显著升高.Zn的K边小波转换结果表明,ZnN_(4)P/C催化剂中Zn原子的最大等高强度中心相对于ZnPc发生了偏移,进一步表明P的引入对Zn的电子结构产生了影响.优化后的ZnN_(4)P/C催化剂在0.1 mol·L^(-1)KOH电解质中的ORR半波电位为0.861 V,比单金属ZnN_(4)/C和Pt/C(20%)更高.此外,将该催化剂用于锌空电池的阴极ORR催化剂,所得电池的最大峰值功率密度(249.6mWcm^(-2))、比电容(779 mAhg^(-1))均优于贵金属Pt/C催化剂,且该电池能够在10 mAcm^(-2)条件下可稳定充放电循环150 h.DFT计算结果表明,ORR活性大幅提高可归因于P的掺杂使电荷在N和Zn周围富集,从而优化了活性中心与O2结合能,并加快了ORR反应的电子转移速度.

The main objective of this research is to design a state-feedback controller for the rotary inverted pendulum module utilizing the linear quadratic regulator(LQR)technique.The controller maintains the pendulum in the inverted(upright)position and is robust enough to reject external disturbance to maintain its stability.The research work involves three major contributions:mathematical modeling,simulation,and real-time implementation.To design a controller,mathematical modeling has been done by employing the NewtonEuler,Lagrange method.The resulting model was nonlinear so linearization was required,which has been done around a working point.For the estimation of the controller parameters,MATLAB LQR function has been utilized.Simulation has been performed for the designed controller and it also has been implemented and tested over the real inverted pendulum.From the results,it is vivid that the designed controller keeps the inverted pendulum in an upright position and rejects the disturbances and falling under gravitational force by adjusting the rotation of the horizontal link.

In the re-entry phase of a ballistic missile,decoys can be deployed as a mean to overburden enemy defenses.This results in a single track being split into multiple track-lets.Tracking of these track-lets is a critical task as any miss in the tracking procedure can become a cause of a major threat.The tracking process becomes more complicated in the presence of clutter.The low detection rate is one of the factors that may contribute to increasing the difficulty level in terms of tracking in the cluttered environment.This work introduces a new algorithm for the split event detection and target tracking under the framework of the joint integrated probabilistic data association(JIPDA)algorithm.The proposed algorithm is termed as split event-JIPDA(SE-JIPDA).This work establishes the mathematical foundation for the split target detection and tracking mechanism.The performance analysis is made under different simulation conditions to provide a clear insight into the merits of the proposed algorithm.The performance parameters in these simulations are the root mean square error(RMSE),confirmed true track rate(CTTR)and confirmed split true track rate(CSTTR).

Ten spices marketed in Jordan, (Syzygium aromaticum L., Coriadrum sativum L., Cuminum cyminum L.,Zingiber officinale Rosc., Elettaria cardamomum, Curcuma longa, Rhus coriaria L., Cinnamomum zeylanicum Blume, Foeniculum vulgare Mill and Laurus nobilis L.) were investigated for their phenolic compounds and antioxidant activity. The influence of different extractants (methanol, ethanol and acetone) at different temperatures (20, 40 and 60°C) was examined. Results showed at 60°C using methanol, cloves had the highest level of total phenolics (781.0 mg GAE/100g using acetone). At 40°C, sumac and cloves had the highest amounts of total phenolics (343.9 mg/100g and 342 mg GAE/100g respectively). At 20°C, cloves continued to have the highest amount of total phenolics (394.7 mg/100g) using methanol as extactant. Ethanol as extractant, cloves gave the highest level of phenolics (548 mg GAE/100g, 493.4 mg GAE/100g) at 60°C, while at 20°C cloves and sumac showed the highest concentrations of phenolics (350.8 mg GAE/100g and 342.8 mg GAE/100g respectively). Acetone as extractant at 60°C, cloves had the highest levels of phenolics (781 mg GAE/100g) while at 40°C and at 20°C, sumac contributed the highest levels of total phenolics (583.2 mg GAE/100g and 754.5 mg GAE/100g). The total phenolics concentration varied significantly among the spices. Their values varied according to the extractant and extracting temperature. IC50 (radical scavenging activity) reflecting the antioxidant activity was presented. Results showed that cloves had the highest antioxidant activity while the cinnamon, turmeric and sumac had a appreciable level of antioxidant activity. Green cardamom and coriander had the lowest antioxidant activity. Antioxidant activity was positively correlated with total phenolic compounds content of the investigated spices.

Al-Rabadi Department of Nutrition and Food Technology Faculty of Agriculture Jordan University of Science and Technology Irbid Jordan Department of Food Science and Human Nutrition University of Illinois Urbana-Champaign USA Department of Animal Production Faculty of Agriculture Mutah University Al-Karak Jordan

Total anthocyanins of spices (Syzygium aromaticum L., Coriadrum sativum L., Cuminum cyminum L., Zingiber officinale Rosc., Elettaria cardamomum, Curcuma longa, Rhus coriaria L., Cinnamomum zeylanicum Blume, Foeniculum vulgare Mill and Laurus nobilis L.) were determined using acidified (1% HCl) solvents (methanol, ethanol and acetone) at three temperatures (20℃, 40℃ and 60℃). Also phenolic acids were separated and identified by RP-HPLC. Results showed that sumac and cinnamon had the highest levels of anthocyanins, while for the acetone the cinnamon indicated the highest amount of anthocyanins when methanol and ethanol were used as extracting solvents at 20℃. At 40℃ using ethanol, sumac showed the highest level of anthocyanins whereas acetone solvent yielded the highest anthocyanin contents for cinnamon. At 60℃, cinnamon showed the highest level of anthocyanins when methanol and acetone were the solvents, while sumac had the highest anthocyanins level using ethanol as solvent. HPLC results showed ten phenolic acids found in those spices and varied in their concentrations. Gallic acid had the highest level (1642.3 mg/100g) (cloves). Gentisic acid had the lowest level (1.2 mg/100g) in ginger. Also sumac showed the highest level of chlorogenic acid (1528.7 mg/100g). Some acids were not found in some spices, for instance, benzoic acid was not found in coriander, cumin, ginger, green cardamom, cinnamon and sweet laurel.
