Summary: Theoretically, excellent non-toxic fluorescent graphene quantum dots (GQDs) with near-infrared (NIR) fluorescence have been achieved for bio-imaging and sensing applications. Cheap and non-toxic sulfur and its group elements were used for doping. The effect of doping position on energy band gap, absorption, and fluorescence properties was studied. The highest quantum yield (QY) of 26% in NIR was obtained for sulfur-doped GQDs (S-GQD: C52S2H18), which is higher than the previous 7% and the first reported high QY in NIR.

Summary: A theoretical investigation on the electronic states in triangular MoS2 quantum dots of different sizes is conducted using density functional theory. The results show that the magnetic properties of the quantum dots evolve from being semiconductor-like to nearly half-metallic with increasing size. Doping can alter the magnetic behavior of the dots, and the doping density can affect the total magnetic moment response. The optical properties are not sensitive to incident light polarization, but they do depend on the spin orientation.

Summary: This article reports on the rational design of a pH sensor using nitrogen-doped graphene quantum dots (NGQDs) and enhancing its properties through microplasma-enabled band-structure engineering. The NGQDs with tunable emission can be synthesized from chitosan biomass precursor under ambient conditions. The NGQDs with enriched -OH functional groups and stable and large Stokes shift can achieve rapid, label-free, and ionic-stable pH sensing over a wide range. The pH sensing mechanism is related to the protonation/deprotonation of -OH group, leading to a luminescence peak shift.

Summary: This study reveals that a giant Berry curvature dipole (BCD) can be achieved in non-magnetic elemental honeycomb lattice materials, such as silicene, germanene, and stanene, through the combined effect of a transverse electric field and strain. The topology of the electronic wavefunction switches from a band inverted quantum spin Hall state to a normal insulating state without a band gap closure at the critical electric field strength. This phenomenon can be experimentally verified and leads to the emergence of a switchable nonlinear electrical and thermal Hall effect.

Summary: Organic materials are a sustainable alternative to replace inorganic transition metal-based cathodes in rechargeable intercalation batteries. Among them, conjugated polymers with multiple redox sites per repeat unit show high energy and power densities with resistance to dissolution. In this study, using diketopyrrolopyrrole (DPP)-based donor-acceptor (D-A) polymers, it is found that minimizing charge localization on the electron accepting repeat units leads to near theoretical discharge capacities. Furthermore, this capacity enhancement improves the rate performance and electrochemical stability of the polymer during prolonged cycling.

Summary: A series of mononuclear manganese(iii) complexes with various ligand substituents were synthesized and their spin-state switching behavior was investigated. The structural effect was found to play a more significant role in the spin-state switch than the electronic effect from different substituents. The transition temperature for the spin-state switch varied depending on the ligand substituent, with different complexes showing gradual or abrupt transitions.

Summary: The role of non-Hermiticity in the Chern insulating Haldane model on a dice lattice is systematically investigated in this work. Two types of non-Hermiticity, balanced non-Hermitian gain and loss, and nonreciprocal hopping, induce higher-order exceptional points of order three. The finite-sized lattice under nonreciprocal hopping exhibits a non-Hermitian skin effect, while the balanced gain and loss case does not. The occurrence of the skin effect and its robustness to disorder are demonstrated using various techniques.

Summary: This article systematically explores the structural, electronic, and thermal transport characteristics of bilayer tetragonal graphene using first-principles calculations and machine-learning interatomic potential approaches. The study confirms metallic band structure similar to monolayer T-graphene, and analyzes the thermal conductivity, Seebeck coefficient, and electrical conductivity of the bilayer TG structure. The results show linearly increasing electronic thermal conductivity with temperature while the lattice part exhibits the opposite behavior, and the Seebeck coefficient transitions from negative to positive values with increasing temperature. The study also verifies the Wiedemann-Franz law and confirms the Debye model behavior of specific heat at low temperature for the bilayer TG structure.

Summary: This study investigated the structures of two Se chains confined inside single-walled carbon nanotubes (SWCNTs), revealing that the chains were linear and parallel. The covalent bond between Se and SWCNT was found to be stronger than that between Se and trigonal Se (t-Se). The interaction between chains was attributed to the overlap of electronic orbitals, and the disappearance of this overlap in the encapsulated Se chains enhanced the covalent bonds.

Summary: In this study, we elucidate the hopping mechanism of hydrogen at intermediate temperature using a combination of experimental data and theoretical calculations. We find that the transition from thermal hopping to quantum tunneling is attributed to resonant tunneling, which is achieved through the resonant tunneling of discrete vibrational states between the edge octahedral site and the tetrahedral site. We also demonstrate that the tunneling rate can be tuned by energy level matching.
