Qudit is a multi-level computational unit alternative to the conventional 2-level qubit. Compared to qubit, qudit provides a larger state space to store and process information, and thus can provide ...reduction of the circuit complexity, simplification of the experimental setup and enhancement of the algorithm efficiency. This review provides an overview of qudit-based quantum computing covering a variety of topics ranging from circuit building, algorithm design, to experimental methods. We first discuss the qudit gate universality and a variety of qudit gates including the pi/8 gate, the SWAP gate, and the multi-level controlled-gate. We then present the qudit version of several representative quantum algorithms including the Deutsch-Jozsa algorithm, the quantum Fourier transform, and the phase estimation algorithm. Finally we discuss various physical realizations for qudit computation such as the photonic platform, iron trap, and nuclear magnetic resonance.
Conversion of biomass-derived sources into 5-hydroxymethylfurfural (HMF), a value-added platform chemical, has attracted great research interest motivated by the raising economic and environmental ...incentives. This review assesses the recent advance on the catalytic system of HMF production, with a main focus on the function of emerging catalysts, solvent system, and advanced reactor. A general overview of HMF production, the correlation between the catalyst physicochemical properties, with a special attention on the acidity property, and the catalytic activity under various reaction parameters, such as solvent or reactor have been summarized and compared. Besides, the reaction mechanism of HMF synthesis was discussed in details, which is helpful for designing novel catalyst with better catalytic activity and improving the stability. Research efforts to clarify the interactions among co-catalysts/co-solvents and between catalysts and solvents have been also classified. Future efforts on developing a synergistic catalytic system for biomass valorization has been pointed out.

Electronic metal–support interactions (EMSIs) are demonstrated to severely affect the CO oxidation activity and the CO adsorption properties of Au/TiO2 catalysts. Bulk oxygen vacancies, generated by ...a strongly reductive pretreatment of Au/TiO2 at elevated temperature in 10% CO/N2, significantly lower the catalytic activity for CO oxidation at 80 °C. With time on stream, the activity slowly increases until reaching the same steady-state value as that obtained for a previously calcined and, hence, defect-poor Au/TiO2 catalyst (activation period), where the time required for the activation period decreases with reaction temperature but is independent of the oxygen partial pressure. Considering the similar Au particle sizes and Au loadings, we conclude that the different activities originate from the presence of bulk oxygen vacancies generated during pretreatment, which are slowly replenished during reaction. In situ IR spectroscopy measurements reveal that the lower activity in the presence of bulk defects is coupled with and likely results from a strong modification of the CO adsorption strength on the reduced Au/TiO2 catalysts due to EMSIs. A possible mechanism explaining how these EMSIs may be induced by the presence of bulk defects is discussed.
In this study, an electrokinetic technique for remediation of Pb2+, Zn2+ and Cu2+ contaminated soil was explored using sodium alginate (SA) and chitosan (CTS) as promising biodegradable complexing ...agents. The highest Cu2+ (95.69%) and Zn2+ (95.05%) removal rates were obtained at a 2 wt% SA dosage, which demonstrated that SA significantly improved the Cu2+ and Zn2+ removal efficiency during electrokinetic process. The abundant functional groups of SA allowed metal ions desorption from soil via ion-exchange, complexation, and electrolysis. Pb2+ ions were difficult to remove from soil by SA due to the higher gelation affinity with Pb2+ than Cu2+ and Zn2+, despite the Pb2+ exchangeable fraction partially transforming to the reducible and oxidizable fractions. CTS could complex metal ions and migrate into the catholyte under the electric field to form crosslinked CTS gelations. Consequently, this study proved the suitability of biodegradable complexing agents for treating soil contaminated with heavy metals using electrokinetic remediation.

Metal-organic frameworks (MOFs) as a type of crystalline heterogeneous catalysts have shown potential application in photocatalytic CO2 reduction. However, MOF catalysts with high efficiency and ...selectivity are still in pursuit. Herein, by a bimetallic strategy, the catalytic performance of a Co-MOF for photocatalytic CO2 reduction was enhanced. Specifically, the Co-MOF based on 4,5-dicarboxylic acid (H3IDC) and 4,4ʹ-bipydine (4,4ʹ-bpy) can catalyze CO2 reduction to CO, with high efficiency but relatively low selectivity. After replacement of 2/3 Co(II) with Ni(II) within Co-MOF, the resulted isostructural Co1Ni2-MOF not only retains high efficiency for photocatalytic CO2 reduction, but also shows enhanced CO selectivity. The CO evolution rate reaches 1160 µmol g−1 h−1 and the CO selectivity reaches as high as 94.6%. The enhanced photocatalytic CO2 reduction performance is supported by theoretical calculation results. This case demonstrates that bimetallic strategy is an effective mean to optimize the catalytic performance of MOF catalysts for photochemical CO2 reduction.

Ruthenium complexes have attracted a surge of interest as anticancer drug candidates because of their low toxicity, diversity in mode-of-actions and non-cross drug resistance with conventional ...platinum-based agents. Despite remarkable advances, only a limited number of ruthenium complexes have been demonstrated to kill cancer cells and suppress metastasis simultaneously. Here, two organometallic tetranuclear Ru(II) arene complexes (Ru-1 and Ru-2) have been synthesized and evaluated for their in vitro activity against a panel of human cancer cell lines, including a cisplatin-resistant human lung cancer A549 cell line. A superior cytotoxic activity of the ruthenium complexes compared to cisplatin across distinct cell lines was observed. Further examination of the mechanism indicated that anticancer activity was accomplished by inducing apoptosis in cancer cells. In addition, we found that such compounds exhibited promising antimetastatic activity and reduced the invasiveness of cancer cells. Importantly, choosing Ru-1 as a target compound, a significantly enhanced safety profile relative to cisplatin in animals was validated, suggesting that these complexes can be used as promising candidates for cancer therapy and deserve further investigation.
