Thermally driven magnetic-molecular junctions can be designed as pure spin current generators, thermoelectric devices or thermal-spin converters.
Using a scanning tunneling microscope, we measured high-bias conductance of single polyporphyrin molecular wires with lengths from 1.3 to 13 nm. We observed several remarkable transport characteristics, including multiple sharp peaks, conductances as high 20 nS in >10 nm, and nearly length-independent (attenuation <0.001 Å–1). carried out first-principles simulations on myriad metal–molecule–metal junctions. The revealed that the is coherent resonant via delocalized orbital.
We study negative differential conductance (NDC) effects in polyporphyrin oligomers with nonlinear backbones. Using a low-temperature scanning tunneling microscope, we selectively controlled the charge transport path single oligomer wires. observed robust NDC when passed through T-shape junction, bistable 90° kink and no 120° kink. Aided by density functional theory nonequilibrium Green's functions simulations, attributed this backbone-dependent to bias-modulated hybridization of electrode...

Abstract Nanozymes are conceived to replace natural enzymes avoid expensive processing techniques and fragile reservation conditions. Unfortunately, the self‐limited reaction has run counter desire for sustainable catalysis as enzymes. Herein, universal mechanism overcome self‐limitation of nanozymes caused by absorption ions on active sites is explored. Therefore, dual noble metals (Au/Pt) introduced center synthesize two kinds with different types central metal elements (Cu Ce) also...
Abstract Current research on single‐atom nanozymes has predominantly concentrated 2D structures, with limited exploration into the influence of 3D biomimetic structures their catalytic performance. In this work, a nanostructure Pt nanozyme (Pt‐NC SAzyme) is fabricated by encapsulating platinum 2,4‐pentanedionate in each molecular cage ZIF‐8 and then pyrolyzing. X‐ray absorption fine structure analysis confirmed presence as single atoms, atom exclusively coordinated four nitrogen while *O...
We observe directly the lattice vibration and its multifold effect on electron transport in zigzag graphene nanoribbons simulation by utilizing an efficient combined method. The results show that fluctuates greatly due to incessant of nanoribbons. More interestingly, behaves like a double-edged sword it boosts conductance symmetric (containing even number chains along width direction) while weakens asymmetric As result, reported large disparity between conductances two kinds at 0 K is fact...
Nodal surface-based topological semimetals (TSMs) are drawing attention due to their unique excitation and plasmon behaviors. However, only nodal flat-surface sphere TSMs theoretically proposed strict symmetry requirements. Here, we propose that a series of phases can be realized in tight-binding (TB) model with sublattice symmetry. These phases, named as flexible-surface semimetals, include not surface but also novel like tube, crossbar, hourglass-like TSMs. According the TB model, family...

In this study, the potential multilayered nanostructures to enhance light trapping improve efficiency was investigated. We successfully synthesized innovative triple-layer Prussian blue nanocubes (tl-Pt@PBNCs) with a multilevel core-shell architecture, optimizing them both structural stability exceptional performance. optical wave...
Two-dimensional (2D) structures hold promise as advanced lithium-ion battery (LIB) anode materials. Recently synthesized 2D graphullerene faces challenges due to its large electronic insulating band gap. In this study, we construct a quasi-tetragonal graphullerene, C36, denoted GrF-C36, using C36 fullerenes with D6h symmetry the structural unit. First-principles calculations revealed that delocalized pz orbitals lead metallicity, combined intrinsic porosity, resulting in theoretical capacity...

Abstract The development of nanomaterials with high photothermal conversion efficiency has been a hot issue. In this work, novel nanomaterial is synthesized using Prussian blue nanocubes (PBNCs) as the active substance and covalent organic framework (COF) substrate. as‐prepared COF@PBNCs show 59.1%, significantly higher than that pure PBNCs (32.5%). A new circuit path generated combination COF, which prevents direct thermal electrons holes, well enhances nonradiation transition PBNCs....
Abstract The ability to control the degree of spin in molecular junctions (MJs) is attractive for their applications spintronics. Here, it demonstrated that spin‐resolved quantum interference (SQI) can effectively improve spin‐filtering behavior MJs. By first‐principle calculations combination with nonequilibrium Green's function investigations, charge transport graphene/Cr‐porphyrin/graphene MJs shows that, due SQI, tunable filtering behaviors be achieved by changing length molecule. SQI...
Promoting white adipose tissue (WAT) "browning" and brown (BAT) activation could contribute to increasing energy expenditure. We explored the mechanisms by which natural compound rutin induced differentiation ameliorated obesity in vivo vitro. 3T3-L1 preadipocytes were cultured adipogenic media with/out rutin. Male C57BL/6 mice (n = 6) fed a high-fat diet (HFD) for 12 weeks In HFD-fed mice, treatment significantly inhibited weight gain, improved metabolic profile of plasma samples, decreased...
