Rechargeable Fe-ion batteries with overwhelming cost/environmental benign superiorities hold great promise in large-scale charge-storage applications. However, there is still a lack of competitive cathodes with prominent capacity and long-term cyclability. To overcome these constraints, a unique Fe 2+ /NH 4 + co-insertion strategy is proposed, enabling both doubled reversible capacity and cyclic life of Berlin green (FeHCF) cathodes. The Fe 2+ insertion proves to induce FeHCF lattice contractions, alter ligand environment/activation energies of low-spin Fe III, and hence boost the redox conversion depth, while NH 4 + co-insertions help to elevate the cathode capacities by utilizing Fe 2+ -unoccupied reaction sites. Besides, they generate hydrogen bonds between inserted NH 4 + ions and N atoms in FeHCF, capable of vastly strengthening the cathode's cyclic durability. Cathodes in such collaborative dual-cation electrolytes exhibit a remarkable capacity of 162 mAh g −1 (4 A g −1 ) and far prolonged operation lifespan (over 1000 cycles) when compared to single-cation cases. The assembled full cells demonstrate impressive energy densities up to 70.4 Wh kg −1 , and far superior capacity retention of 88% after all the cycling. This work may offer a simple/feasible, and effective route to render high-capacity and long-lasting cathodes for future/practical Fe-ion battery systems.

Intercalation, the insertion of guest atomic and molecular entities into the architecture of a crystal, is an efficient route for generating new materials with novel properties. However, the detailed analysis of their new structure and properties is of great importance, which are still insufficient. Here, 1,2-bis(4-pyridyl)ethylene (BPE) intercalated PbI 2 (BIP) has been investigated by Raman spectroscopy together with correlated studies of scanning electron microscope (SEM), X-ray diffraction (XRD), ultraviolet–visible (UV–Vis) absorption spectrum, and energy-dispersive X-ray spectroscopy (EDS). The Raman spectrum of intercalated compound discloses new lines at 83, 222, and 234 cm −1 with remarkable displacement of the bands at 1001, 1200, 1603, and 1640 cm −1 , indicating a formation of a new crystal and the chemical interaction between the nitrogen atom of guest molecules with PbI 2 host material. XRD confirmed the intercalation of guest molecules into a host matrix through the appearance of diffraction lines at lower angles that are corresponding to the enlarged unit cell in c axis. Furthermore, we also found that the PbI 2 can specifically adsorb of BPE molecules, which was confirmed by an adsorption experiment revealed by adsorption capacity toward BPE is higher than 2,2-bipyridine and 4,4-bipyridine, suggesting the good adsorptive selectivity toward BPE by PbI 2 film. This work further demonstrated our mechanism on enhanced Raman spectroscopy on PbI 2 . It is believed that this unusual discovery not only enables PbI 2 to be a specific adsorbent, which also provides a new advance toward a better understanding of structure about PbI 2 .

The binding of tiamulin with calf thymus DNA was systematically investigated using multispectroscopy and molecular modelling techniques. For DNA, once tiamulin was added, viscosity ( η ) and melting temperature ( T m ) both exhibited an uptrend. The fluorescence performance of the tiamulin–DNA complex did not change with the ionic strength changes. The binding constant ( K a ) of tiamulin for single-stranded DNA (ssDNA, 1.48 × 10 4 M −1 ) was obviously higher than that for double-stranded DNA (dsDNA, 9.51 × 10 3 M −1 ) at 291 K. The helix structure became looser and the base stack force became stronger for DNA due to the presence of tiamulin as seen from circular dichroic (CD) spectra. The intercalation binding mode of tiamulin with DNA was disclosed. Molecular modelling also revealed tiamulin inserting into the base pairs with the lowest binding free energy of −18.73 kJ mol −1 using van der Waals forces as well as hydrogen bonds.

Developing insertion-type anodes is essential for designing high-performance “rocking chair” zinc-ion batteries. BiOCl shows great potential as an insertion-type anode material for Zn 2+ storage due to its high specific capacity and unique layered structure. However, the development of BiOCl has been significantly hampered by its poor stability and kinetics during cycling. In this study, Br-doped and carbon-coated BiOCl ultrathin nanosheets (Br-BiOCl@NC) are synthesized as high-performance anodes. The ultrathin nanosheet morphology facilitates Zn 2+ /H + transfer and the Br doping reduces the Zn 2+ /H + diffusion barrier. Additionally, the carbon coating enhances the electronic transfer. Furthermore, an insertion-conversion mechanism involving H + and Zn 2+ storage is revealed by ex-situ tests. Therefore, Br-BiOCl@NC exhibits a high discharge capacity of 174 mA h/g at 500 mA/g without capacity degradation after 1000 cycles. The Br-BiOCl@NC//MnO 2 full cell presents a discharge capacity of ≈ 120 mA h/g at 200 mA/g. This work offers valuable insights for the design of high-performance insertion-type anode materials in zinc-ion batteries.

Aqueous zinc-ion batteries (ZIBs) have attracted significant attention due to their intrinsic safety, cost-effectiveness, and environmental friendliness. However, the common zinc metal anode suffers from zinc dendrite formation, self-corrosion, and surface passivation, which impede the further application of aqueous ZIBs. Herein, carbon-inserted molybdenum dioxide (MoO 2 ) materials with laminated structure are designed as novel intercalation-type anodes for ZIBs by combination of interlayer engineering and in situ carbonization of aniline guest in molybdenum trioxide interlayers. The uniform dispersion of carbon layers in laminated MoO 2 not only provide fast transportation paths for electron but also strengthen the framework of MoO 2 , leading to high structural integration during high-rate cycling. Benefiting from the unique structural design, the carbon-inserted MoO 2 electrode exhibits high initial Coulombic efficiency, excellent cycling stability, and outstanding rate capability. Multiple ex situ characterizations reveal its excellent electrochemical stability is derived from reversible intercalation mechanism and ultrastable structural framework. Furthermore, the rocking-chair zinc-ion full battery assembled with the zinc pre-intercalated Na 3 V 2 (PO 4 ) 2 O 2 F cathode presents excellent stability and ultralong lifespan with a high capacity retention of 91% over 8000 cycles.

Carbon -MoS 2−x @CdS (C-MoS 2−x @CdS) core-shell nanostructures with controlled surface sulfur (S) vacancies were prepared via a glucose assisted hydrothermal growth method. The glucose acted as a reducing agent of C-MoS 2−X to partially reduce Mo 4+ ions to Mo 3+ and served as a carbon source to insert the amorphous carbon into the layered MoS 2−X simultaneously. The presence of Mo 3+ result in the surface S-vacancies, which can provide more additional active sites and enhance the photocatalytic performance. Moreover, the inserted carbon in layered MoS 2−X enhanced the electron mobility and decreased the resistance electron transfer. Density functional theory (DFT) calculation confirmed that the surface S-vacancies and the amorphous carbon increase the projected density of states at the conduct band edge, which could enhance the photo-absorption and photo-responsibility. The result is consistent with the photocatalytic H 2 production experiment . C2-10%MoS 2−x @CdS presented a high H 2 evolution rate of 61,494 μmol h −1 g −1 under visible light irrigation (λ ≥ 420 nm), which is 1.98 times and 158 times higher than that of sample without S-vacancies (10%MoS 2 @CdS) and pure CdS, respectively.

The recycling of waste rubber (WR) is beneficial to the sustainable development of rubber industries. However, interactions among WR are weak, limiting the recycling of WR. In this work, our group designed bis-diazo compounds to promote interactions among WR for recycling through aliphatic C–H insertion strategies. Specifically, upon hot pressing, bis-diazo compounds produce bis-carbenes which react with C–H on the surface of WR by C–H insertions, and then we obtain recycled WR materials. As a result, stress–strain curves show that the strength of recycled WR increases steadily with the increase of bis-diazo compound loading, which has reached the level of butadiene styrene rubbers. Moreover, the introduced disulfide bonds endow recycled WR with reprocessability. Stress–relaxation experiments at different temperatures show that recycled WR with disulfide bonds have unique vitrimer viscoelastic properties. The feasibility of bis-diazo compounds to enhance interactions among WR through C–H insertions opens opportunities to recycle and reinvent industrial WR.

The aggregation of transition metal nanoparticles severely degrades their catalytic activity towards water splitting. Although this issue can be alleviated by the popular carbon-hybridization and metal foam-confinement strategies, the complicated fabrication procedure and the support corrosion parasitic in these strategies inevitably result in high usage cost and unsatisfactory cycle durability. Herein, we in-situ space-confined boron-inserted Fe-Ni solid solution nanosheets onto the activated hydrophilic sponge (B-FeNi@HS) via substitution of Fe by Ni and insertion of B within the Fe lattice interstitials in the presence of NH 4 + -modified dimethylamino borane solution. When served as the bifunctional electrocatalysts, B-FeNi@HS only needs overpotentials of 54 and 171 mV to afford 10 mA cm –2 for HER and OER in 1.0 M KOH, respectively. In addition, the alkaline overall-water splitting system constructed by using B-FeNi@HS as two-electrodes only delivers an ultralow cell voltage of 1.456 V to drive 10 mA cm –2 , and shows negligible activity decay even at 500 mA cm –2 for 3 days. Such outstanding performance can be traced to the synergism of corrosion-resistant support, hierarchical morphology with favorable surface area and dual solid-solution crystal structure, ensuring robust mechanical stability, rapid charge/mass transfer kinetics as well as the energetically favorable formation of intermediates during catalysis. The proposed strategy is versatile and can be extended to synthesize other efficient B-inserted Fe-based electrocatalysts.

This study explored the genomic alterations in Yarrowia lipolytica, a key yeast in industrial biotechnology, under both spontaneous and mutagen-induced conditions. Our findings reveal that spontaneous mutations occur at a rate of approximately 4 × 10−10 events per base pair per cell division, primarily manifesting as single-nucleotide variations (SNVs) and small insertions and deletions (InDels). Notably, C-to-T/G-to-A transitions and C-to-A/G-to-T transversions dominate the spontaneous SNVs, while 1 bp deletions, likely resulting from template slippage, are the most frequent InDels. Furthermore, chromosomal aneuploidy and rearrangements occur, albeit at a lower frequency. Exposure to ultraviolet (UV) light, methylmethane sulfonate (MMS), and Zeocin significantly enhances the rates of SNVs and alters their mutational spectra in distinct patterns. Notably, Zeocin-induced SNVs are predominantly T-to-A and T-to-G substitutions, often occurring within the 5′-TGT*−3′ motif (* denotes the mutated base). Additionally, Zeocin exhibits a higher potency in stimulating InDels compared to UV and MMS. Translesion DNA synthesis is implicated as the primary mechanism behind most Zeocin-induced SNVs and some InDels, whereas non-homologous end joining serves as the main pathway for Zeocin-mediated InDels. Intriguingly, the study identifies the gene YALI1_E21053g, encoding a protein kinase, as negatively associated with Zeocin resistance. Overall, our results not only deepened our knowledge about the genome evolution in Y. lipolytica but also provided reference to develop innovative strategies to harness its genetic potential.

Microneedles, as a new efficient and safe transdermal drug delivery technology, has a wide range of applications in drug delivery, vaccination, medical cosmetology, and diagnostics. The degree of microneedles penetration into the skin determines the reliability of the delivery dose, but its evaluation is not yet well-established, which is one of the major constraints in the commercialization of microneedles. In this paper, a novel visual simulated skin model was developed with reference to the physical properties of real skin. The simulated skin model was well-designed and its prescription was optimized to make the thickness, hardness, elasticity, and other parameters close to those of real skin. It not only meets the need to assess the degree of insertion of microneedles but also provides a visual observation of the insertion state of microneedles.

2D room-temperature magnetic materials are of great importance in future spintronic devices while only very few are reported. Herein, a plasma-enhanced chemical vapor deposition approach is exploited to construct the 2D room-temperature magnetic MnGa 4 -H single crystal with a thickness down to 2.2 nm. The employment of H 2 plasma makes hydrogen atoms can be easily inserted into the MnGa 4 lattice to modulate the atomic distance and charge state, thereby ferrimagnetism can be achieved without destroying the structural configuration. The as-obtained 2D MnGa 4 -H crystal is high-quality, air-stable, and thermo-stable, demonstrating robust and stable room-temperature magnetism with a high Curie temperature above 620 K. This work enriches the 2D room-temperature magnetic family and opens up the possibility for the development of spintronic devices based on 2D magnetic alloys.

Non-classical Fischer–Tropsch to olefins (FTO) is a crucial yet highly complex industrial reaction that enables the direct conversion of syngas, derived from renewable feedstocks such as biomass, municipal solid waste, or captured CO 2 , into long-chain olefins (C 5+ = ) via a carbide mechanism. Here, we systemically investigate mechanisms and performance of Na-modified Ru/TiO 2 catalysts in non-classical FTO, and experimentally discover a new CO insertion pathway. Our findings show that Na modification alters the adsorption and activation behaviors of CO, H 2 and intermediates, eventually manipulating reaction mechanisms. The Ru/TiO 2 catalyst with less Na exhibits high CO dissociation and C-C coupling abilities but a poor dehydrogenation ability, which mainly obeys the carbide mechanism, benefiting to produce C 5+ alkanes, rather than olefins. However, excessive addition of Na would primarily make the Ru/TiO 2 catalyst alternately follow the CO insertion mechanism, preferring to produce short olefines (C 2-4 = ) because of the poor C-C coupling ability. After rational coordination of the two pathways through regulating the Na loadings, the 0.5NaRu/TiO 2 catalyst robustly exhibits ultra-high C 5+ = selectivity (80.9%) and impressive C 5+ = space time yield (1.68 × 10 -2 mol CO g cat -1 h -1 ) at 260 °C, without deactivation for over 100 h. These findings not only provide fundamental insights into the underlying mechanisms for long-chain olefin synthesis, but also offer theoretical guidance for developing advanced catalysts for industrial applications.
