论文题目:Coupling efficient biomass upgrading with H2 production via bifunctional CuxS@NiCo-LDH core–shell nanoarray electrocatalysts

论文摘要:To boost hydrogen production from water splitting, the electrochemical oxidation of biomass-derived molecules to produce valuable chemicals is regarded as a promising approach to replace the kinetically sluggish oxygen evolution reaction. Herein, copper sulfide nanowire@NiCo-layered double hydroxide (LDH) nanosheet core–shell nanoarrays are fabricated as efficient bifunctional electrocatalysts for 5-hydroxymethylfurfural (HMF) oxidation and water reduction to simultaneously produce value-added 2,5-furandicarboxylic acid (FDCA) and hydrogen fuel with less energy consumption. Benefiting from the fast charge transfer induced by the CuxS core, the Co/Ni interaction in the LDH nanosheet layer and the open nanostructure, the optimized catalysts exhibit superior electrocatalytic activity (record-high 87 mA cm−2 @ 1.3 V vs. RHE for HMF oxidation; η = 107 mV @ 10 mA cm−2 for HER) and durability; the faradaic efficiency towards FDCA and H2 is close to unity. The bifunctional two-electrode electrolyzer only requires a low voltage of 1.34 V to co-generate H2 and FDCA at 10 mA cm−2. This work highlights the significance of tuning the redox properties of transition metals and constructing nanoarray electrocatalysts towards more efficient energy utilization.

论文题目:Crosstalk shielding of transition metal ions for long cycling lithium–metal batteries

论文作者:Xue-Qiang Zhang, Xin-Meng Wang, Bo-Quan Li, Peng Shi, Jia-Qi Huang, Aibing Chen, Qiang Zhang  

发表日期:February 28, 2020

论文摘要:Lithium–metal batteries (LMBs) comprising a lithium anode and high-specific-capacity manganese (Mn)-based cathode provide a promising high-energy-density system. However, this full cell suffers from poor cycling life under practical conditions. In this contribution, the effect of transition metal ions, e.g., Mn ions, dissolved from the cathode on the failure of lithium anodes was investigated in a working cell. Mn ions are involved in the formation of the solid electrolyte interphase (SEI), inducing the emergence of Mn content and a decrease in the Li2O and LiF components in the SEI; this results in inhomogeneous lithium nucleation. Furthermore, the direct chemical reaction between Mn ions and lithium anodes results in anode corrosion. For the crossover shielding of Mn ions, a graphene-coated separator was proposed to obstruct Mn ions by adsorption for lithium protection, prolonging the lifespan of LMBs under harsh conditions. This study not only highlights the impact of dissolved transition metal ions, such as Mn ions, on the stability of lithium anodes but also affords a practical strategy to shield the crossover of transition metal ions for anodic protection in both present lithium-ion and next-generation batteries.

论文题目:An electron-donating strategy to guide the construction of MOF photocatalysts toward co-catalyst-free highly efficient photocatalytic H2 evolution

论文作者:Dapeng Dong, Chaoxiong Yan, Jindou Huang, Na Lu, Pengyan Wu, Jian Wang, Zhenyi Zhang

发表日期:November 14, 2019

论文摘要:Herein, an interesting electron-donating strategy is proposed to guide the construction of novel CdS-based MOFs for co-catalyst-free photocatalytic H2 evolution in the presence of triethanolamine as the hole-scavenger. The optimally designed CdS-based MOF exhibits an exceptional H2-evolution rate of 26.1 mmol g−1 h−1 which is almost the highest rate among the reported co-catalyst-free MOF systems.

论文题目:Ultra-Sensitive Detection and Inhibition of the Metastasis of Breast Cancer Cells to Adjacent Lymph Nodes and Distant Organs by Using Long-Persistent Luminescence Nanoparticles

论文摘要:The metastasis of breast cancer mainly occurs through the axillary lymph node and blood circulation systems. It is extremely difficult to know when the cancer cells start to metastasize; however, early detection of breast cancer metastasis is crucial and challenging to enable surgical removal of the primary tumor and perform a systematic lymphadenectomy to eliminate invasion of the tumor. Herein, we report real-time tracking of the metastasis of orthotopic breast cancer with background-free near-infrared long-persistent luminescence (NIR-PL) imaging, and its guidance for the surgical removal of lymph nodes. The NIR-PL imaging is based on Cr3+/Nd3+ codoped ZnGa2O4 (A-ZGCN) nanoparticles with a superlong afterglow time of more than 15 days. We show that the detection sensitivity of metastasis of cancer cells with the NIR-PL imaging is higher than the classic bioluminescence imaging. We find that the metastasis of breast cancer cells to lymph nodes occurred as early as on the third day after orthotopic inoculation of breast cancer cells and followed an order of the proper axillary lymph node (PALN, day 3) > accessory axillary lymph node (AALN, day 6) > accessory mandibular lymph node (AMLN, day 9) > mandibular lymph node (MLN, day 25). In addition, we show that the NIR-PL nanoprobes (i.e., A-ZGCN NPs) displayed 17% radioenhancement, which was used for radiotherapy of orthotopic breast cancer to further prevent and reduce its metastasis to other organs. The radiotherapy treatment is superior to surgery for removal of the tumor accompanied by a NIR-PL imaging-guided lymphadenectomy. Our work demonstrates the great potential of NIR-PL imaging and the corresponding nanoprobes for tracking metastasis of cancer cells and for radiotherapy.

论文题目:Bio-inspired Nanocomposite Membranes for Osmotic Energy Harvesting

论文作者:Cheng Chen, Dan Liu, Li He, Si Qin, Jiemin Wang, Joselito M. Razal, Nicholas A. Kotov, Weiwei Lei

发表日期:December 18, 2019

论文摘要:ayered membranes engineered with molecular-scale precision from aramid nanofibers and BN nanosheets simultaneously display high stiffness and tensile strength even when exposed to repeated pressure drops and salinity gradients. The total generated power density over large areas exceeded 0.6 W m −2 and was retained for as long as 20 cycles (200 h), demonstrating exceptional robustness. Furthermore, the membranes showed high performance in osmotic energy harvesting in unprecedentedly wide ranges of temperature (0°C–95°C) and pH (2.8–10.8) essential for the economic viability of osmotic energy generators.
