Anode-free lithium metal batteries (AFLMBs) are promising due to ultrahigh energy density, reduced manufacturing costs, and enhanced safety through active lithium elimination. However, their practical implementation remains challenged by unstable electrode-electrolyte interfaces and the resulting rapid active species depletion. Herein, an ultrathin ion-conducting membrane (ICM) is designed, featuring uniformly distributed rigid benzenesulfonimide anionic groups and flexible lithiophilic groups containing ether oxygen groups. The constrained benzenesulfonimide anions enable exceptional charge separation and reduced spatial resistance, boosting lithium-ion mobility, while the integrated lithophilic network directs lateral lithium deposition through ionic nanochannels. This ICM layer effectively promotes the enrichment of anions at the interface and constructs stable anion-derived solid electrolyte interphases (SEI). Meanwhile, ICM layers with electron-insulating and ion-conducting properties can further prevent side reactions, and suppress dendritic Li growth acting as a natural shield, resulting in seamless lithium deposition. Specifically, the Li||Cu coin cells with ICM achieve 99.82% Coulombic efficiency. The AFLMBs assembled with ICM-coated copper foil (ICM Cu) and NCM811 deliver an energy density of 495 Wh kg-1 with 80.72% capacity retention after 100 cycles. The interphasial chemistry design strategy provides insights into the precise interfacial engineering to realize high-performance, high-safety battery systems and facilitates their development for practical applications.

Precise control of luminescence and singlet oxygen generation is important for selective photo-theranostic applications. In this work, bioorthogonal assembly based on d(10)MIDLINE HORIZONTAL ELLIPSISd(10) metallophilic interactions was first proposed for selective cancer cell imaging and photodynamic therapy (PDT) treatment as a proof of concept. [Au(NHC)(2)](+) (NHC = N-heterocyclic carbene) cations loaded on hyaluronic acid were selectively taken up by cancer cells. The subsequent incubation with [MX2](-) (M = Au or Cu and X = halide or arylacetylide) anions led to the bioorthogonal assembly of C3 + A5/A10 in cancer cells with luminescence turn-on and singlet oxygen generation upon irradiation. This work not only demonstrates that d(10)MIDLINE HORIZONTAL ELLIPSISd(10) metallophilic interactions can be readily harnessed for developing bioorthogonal assembly to realize precise cancer cell imaging and PDT, but also can stimulate the development of supramolecular interaction based bioorthogonal chemistry.

A Ru-anthraquinone dyad with triple functions of PACT, photoredox catalysis and PDT upon red light irradiation

DALTON TRANSACTIONS 2021年第31期50卷 10845-10852页

Phototherapy for cancer treatment has received much attention in recent years, and compounds with multiple anticancer mechanisms upon irradiation are particularly appealing. In this work, a nitro-anthra-quinone group was attached to a biq (2,2'-biquinoline) ligand based Ru(II) complex, endowing the resultant Ru1 compound with multiple anticancer mechanisms upon 600 nm light irradiation. Ru1 can undergo biq ligand photodissociation, showing its potential as a photoactivated chemotherapy (PACT) agent. Moreover, a Ru(III) centre and an anthraquinone anion centre may be generated upon irradiation, which can further oxidize NADH/NADPH and generate O-2(center dot-), successfully eliciting photoredox catalysis and photodynamic therapy (PDT). Compared to the control complex Ru2 without the nitroanthraquinone group, Ru1 exhibited much enhanced photocytotoxicity towards a series of cancer cell lines and 3D multicellular spheroids upon red light irradiation.

Traveling wave solutions are a class of invariant solutions which are critical for shallow water wave equations. In this paper, traveling wave solutions for two perturbed KP-MEW equations with a local delay convolution kernel are examined. The model equation is reduced to a planar near-Hamiltonian system via geometric singular perturbation theorem, and the qualitative properties of the corresponding unperturbed system are analyzed by using dynamical system approach. The persistence of the bounded traveling wave solutions for the perturbed KP-MEW equations with delay is investigated. By using a criterion for the monotonicity of ratio of two Abelian integrals and Melnikov's method, the existence of kink (anti-kink) wave solutions and periodic wave solutions of the model equation are established. The result shows that the delayed KP-MEW equations with positive perturbation and the one with negative perturbation exhibit completely diverse dynamical properties. These new findings greatly enrich the understanding of dynamical properties of the traveling wave solutions of perturbed nonlinear wave equations with local delay convolution kernel. Numerical experiments further confirm and illustrate the theoretical results.

Multi-element transition-metal nitrides possessing combinations of outstanding mechanical and physical properties have attracted increasing attention due to its potential applications. Here, a new transition-metal nitride alloying four metal elements of Ti, W, V and Ta is proposed, in which the doping ratios of these four metal elements are equal. Using an improved structure searching method, the potential structures with low enthalpies were fully explored. An orthorhombic structure was firstly disclosed and verified to be its ground-state phase. It is the most energetically favorable structure in the pressure of 0 similar to 100 GPa. The phonon spectrum calculations demonstrated its lattice dynamical stability. Systematic study of its mechanical properties showed the orthorhombic structure not only possessed a large hardness of 32.4 GPa but also behaved a large indentation shear strength of about 30 GPa, greatly exceeding its well-known fcc-B1 phase (about 15 GPa). Meanwhile, we also compared the orthorhombic phase to its disordered structure within B1 phase by generating special quasirandom structures (SQS) with a 3 x 3 x 3 supercell (216 atoms), which can be viewed as its high-entropy phase. The results displayed this SQS system had comparable hardness and strength but greatly improved ductility and toughness relative to the ordered B1 phase.

This study combined the structural characteristics of amanita peptide toxins to prepare a Fe3O4/P4VPBA/PPy/ GO composite material as a magnetic solid-phase extraction adsorbent. The experimental results indicated that this adsorbent showed excellent selectivity for the extraction of amatoxins and phallotoxins from mushroom samples. Compared with traditional dispersive solid-phase extraction, this adsorbent enables rapid separation in the enrichment and elution recovery stages through the application of a magnetic field. Simultaneously, the study optimized the conditions for ultraperformance liquid chromatography-mass spectrometry (UPLC-MS/MS), ensuring both separation efficiency and accuracy while reducing the analysis time. The researchers established the MSPE-UPLC-MS/MS method for the determination of amanita peptide toxins in wild mushrooms. This method not only simplified and expedited the sample pretreatment process but also achieved qualitative and quantitative analyses in a short period, thus demonstrating high detection sensitivity and outstanding recovery rates. Furthermore, the developed method was successfully applied to analyze toxic mushrooms discovered in Nanjing, China. The potential for extensive utilization of this method is highlighted in the field of food analysis and detection.
