Summary: Accurate measurement of transverse relaxation rates in coupled spin systems is crucial for studying molecular dynamics. Existing experiments such as CPMG and PROJECT can suppress signal modulations but may also suppress relaxation contributions and average relaxation rates between coupled spins. A new experiment has been introduced to accurately measure transverse relaxation rates in coupled protons and determine exchange rate constants in slow exchange.

Summary: Theoretical study of magnetization relaxation in Ising spins with soft-core two-body interaction potential in homogeneous and Gaussian profiles reveals different dynamics between the two cases, with an oscillating behavior and stretched-exponential law observed in the former and coherent manybody dynamics in the latter. The system's disorder level can be controlled by the interspin distance ratio, impacting the magnetization dynamics. Different asymptotic evolution behaviors are observed in different disorder limit scenarios, with stretched exponent values varying from 0.18 to 0.5.

Summary: Efficient chemical transformation is essential for modern society's sustainable development. Enzyme-photo-coupled catalytic systems (EPCS) show promise in solar-driven 'molecular editing', but the design of efficient and stable EPCS is challenged by the involvement of multiple components and catalytic processes. Identifying connectivity and compatibility between biocatalytic and photocatalytic ensembles as crucial factors governing EPCS performance, solutions for undesirable connectivity and low compatibility are discussed to propose designing principles for EPCS and provide a future perspective.

Summary: Dynamic networks with multiple bond types offer engineers another design parameter - relative bond fraction - to control mechanical energy storage and dissipation. However, understanding the emergent properties of these networks is challenging through experiments. In this study, we use a network model with prescribed fractions of dynamic and stable bonds to predict the relaxation characteristics of hybrid networks. Our findings reveal that predominantly dynamic networks can exhibit long-term moduli through conformational inhibition of stable bond relaxation, while predominantly stable networks show minor relaxation through non-affine reconfiguration of dynamic bonds. By introducing a fitting parameter xi to Transient Network Theory, we can accurately predict the stress response and uncover the micromechanical traits of gels with multiple bond dissociation timescales.

Summary: The proposed selectively pulsed generation of sequences effectively transfers the spin order of parahydrogen to heteronuclei in weakly coupled spin systems, showing promise for hyperpolarization of molecules at high magnetic fields. This method is robust and efficient even when precursor molecules are not fully deuterium-labeled, requiring lower radiofrequency power and offering potential applications in hyperpolarization within MRI systems.

Summary: Detecting magnetic noise from small quantities of paramagnetic spins is achieved using spin defects in hexagonal boron nitride (hBN). Negatively charged boron vacancy defects are created in ultra-thin hBN nanoflakes, and the longitudinal spin relaxation time (T1) is measured. By decorating the dry hBN nanopowder with paramagnetic Gd3+ ions, a clear T1 quenching under ambient conditions is observed, indicating the presence of added magnetic noise. Spin measurements, including T1 relaxometry, can also be performed using solution-suspended hBN nanopowder. These findings demonstrate the potential and versatility of hBN quantum sensors for various sensing applications and pave the way towards a truly 2D, ultrasensitive quantum sensor.

Summary: The operator growth dynamics of the transverse field Ising spin chain in one dimension was investigated, showing that it follows a universal scaling law influenced by the longitudinal field. Additionally, a crossover scaling law was observed when the longitudinal field is weak, indicating that a uniform longitudinal field induces chaos in the system at any nonzero value. The implications of the crossover scaling on thermalization dynamics and the effect of a nonuniform local longitudinal field were also discussed.

Summary: This study demonstrates electric-field-effect spin switching using p-doped semiconductor quantum dots, enhancing the number of highly polarized electron and photon spins. The spin direction can be controlled by the strength and direction of the electric field, with optimized p-doping leading to fast spin reversals under moderate electric field application. Excess hole doping hinders efficient spin reversal due to multiple electron-hole spin scattering and a spin-state filling effect during the spin injection process.

Summary: This study investigates the transverse vibration characteristics of an axially loaded beam using parallel-coupled nonlinear isolators to improve low-frequency vibration isolation. The nonlinear isolators employ double annular magnets and spiral springs to achieve high static and low dynamic stiffness suitable for low-frequency vibration isolation. A novel approach is proposed to analyze the frequency response functions of power flow for strongly nonlinear discrete and continuum coupled systems. The results demonstrate that the frequency response function of power flow can effectively deal with transverse vibrations in non-co-located excitation sources and isolation objects. The parallel-coupled nonlinear vibration isolator can decrease the energy transmission of high-order modal vibrations of the continuum, providing significant vibration suppression at low frequencies. Parametric studies show that increasing the beam length and initial axial force can reduce the resonant frequency and broaden the vibration isolation frequency band. An experiment is conducted to validate the accuracy of the theoretical model.

Summary: In this study, 5 nanometer sized detonation nanodiamonds (DNDs) were investigated as potential single-particle labels for distance measurements in biomolecules. Nitrogen-vacancy (NV) defects in the crystal lattice could be detected through their fluorescence and optically-detected magnetic resonance (ODMR). Two complementary approaches based on spin-spin coupling or optical super-resolution imaging were proposed for single-particle distance measurements. The first approach focused on measuring the mutual magnetic dipole-dipole coupling between two NV centers in close DNDs using a pulse ODMR sequence, while the second approach successfully localized the NV centers in DNDs using STORM super-resolution imaging, enabling optical nanometer-scale single-particle distance measurements.

Summary: The design of a solid electrolyte interphase (SEI) plays a crucial role in improving the electrochemical performance of anode materials. In this study, lithium difluoro(oxalate)borate (LiDFOB) is used as an electrolyte additive to form a protective SEI film on Li3VO4 (LVO) anodes. The addition of LiDFOB results in a dense, uniform, stable, and LiF-richer SEI, which enhances the Li-ion storage kinetics. The generated SEI also prevents further decomposition of the electrolyte and maintains the morphology of LVO anodes during charge/discharge processes. This work demonstrates the effectiveness of LiDFOB as a multi-functional additive for LiPF6 electrolytes and provides insights into SEI construction for high-performance LVO anodes.

Summary: In this study, we used density functional theory (DFT) calculations to investigate the interaction between model graphene oxide (GO) nanostructures and chlorine monoxide ClO. We aimed to understand the role of this highly oxidizing species in breaking C-C bonds and forming significant holes on GO sheets. Our results showed that C-C bonds in a single graphene oxide sheet can be broken through a simple mechanism involving the dissociation of two chemically attached ClO molecules. The formation of carbonyl groups and holes on the GO surface was also observed. This study provides important insights into the degradation of carbon nanotubes and the stability of GO during the myeloperoxidase (MPO) catalytic cycle.

Summary: In this study, the X-ray stability of five different lead halide perovskite compositions (MAPbI3, MAPbCl3, MAPbBr3, FAPbBr3, CsPbBr3) was investigated using photoelectron spectroscopy. Different degradation mechanisms and resistance to X-ray were observed depending on the crystal composition. Overall, perovskite compositions based on the MA+ cation were found to be less stable than those based on FA+ or Cs+. Metallic lead formation was most easily observed in the chloride perovskite, followed by bromide, and very little in MAPbI3. Multiple degradation processes were identified for the bromide compositions, including ion migration, formation of volatile and solid products, as well as metallic lead. CsBr was formed as a solid degradation product on the surface of CsPbBr3.

Summary: The stability of La1/3Sr2/3Fe1-xMnxO3-delta, a perovskite-type oxide, under reducing conditions is dependent on the manganese content. Increasing the manganese content leads to a decrease in stability. The behavior of iron and manganese in the oxide shows distinct differences, which can be attributed to the difference in the enthalpy of oxidation reactions. Additionally, the change in the La/Sr ratio affects the concentration of iron and manganese ions.
