Phase transition is common during (de)-intercalating layered sodium oxides, which directly affects the structural stability and electrochemical performance. However, the artificial control of phase transition to achieve advanced sodium-ion batteries is lacking, since the remarkably little is known about the influencing factor relative to the sliding process of transition-metal slabs upon sodium release and uptake of layered oxides. Herein, we for the first time demonstrate the manipulation of oxygen vacancy concentrations in multinary metallic oxides has a significant impact on the reversibility of phase transition, thereby determining the sodium storage performance of cathode materials. Results show that abundant oxygen vacancies intrigue the return of the already slide transition-metal slabs between O_(3) and P_(3) phase transition, in contrast to the few oxygen vacancies and resulted irreversibility. Additionally, the abundant oxygen vacancies enhance the electronic and ionic conductivity of the Na0.9Ni0.3Co0.15Mn0.05Ti0.5O2 electrode, delivering the high initial Coulombic efficiency of 97.1%, large reversible capacity of 112.7 mAh·g−1, superior rate capability upon 100 C and splendid cycling performance over 1,000 cycles. Our findings open up new horizons for artificially manipulating the structural evolution and electrochemical process of layered cathodes, and pave a way in designing advanced sodium-ion batteries.

nuclear graphite is widely used in high-temperature gas-cooled reactors due to its excellent neutron moderation capabilities and mechanical stability at elevated temperatures. However, graphite components in these reactors are exposed to complex environments and diverse loads, including dynamic forces potentially arising from earthquakes, aircraft impacts, and internal explosions. This study investigates the fracture behavior of nuclear-grade graphite, specifically SIAMC fine-grained graphite and IG-11 graphite, under dynamic loading by examining their fracture morphology. Fracture surface roughness of graphite discs was measured, and three-dimensional surface reconstructions were conducted. Results show a significant decrease in surface roughness with increasing strain rates, indicating a trend toward a flatter fracture surface driven by changes in crack propagation paths. Furthermore, the microscopic crack growth mechanism of fine-grained nuclear graphite under dynamic loading is elucidated, enhancing our understanding of its fracture behavior under dynamic conditions. © 2025

The tin-oxo cage ([R12Sn12O14(OH)6]2+) is an excellent photoresist candidate in the EUVL (extreme ultraviolet lithography). Photoionization that leads to plenty of primary and secondary electrons is an inevitable process upon irradiation by EUV light. The secondary electron could cause electron blur and decrease the resolution of the photoresist. The utilization and improvement are limited due to its poorly understood fundamental chemical process. In this paper, the property of complexes formed by the combination of the cage and different counterions (methanesulfonate, tosylate, and triflate) was explored by density functional theory (DFT). The number and species of counterions are closely associated with ionization and electron attachment but show an inconspicuous effect on carbon-tin bond energy. Meanwhile, tin radical could be the reactivity site of ionization (and electron affinity). The activity of radical species is affected by counterions could attribute to the changes in the charge density by diverse counterions, which could be an important factor in why the counterion affects the pattern. And a superb linearity between the ADCH of tin radical and IP/AP was found, indicating that the ADCH could be a simple substitution of complicated calculation for IP (or AP) to screen suitable counterions and improve the resolution of photoresist. © 2023, The Authors.

In nuclear astrophysics, Pr141 is mainly produced by an s process, which has a neutron magic number (N=82) leading to its low capture cross section and strongly affecting the s process. Its neutron capture cross section is an important input parameter for nuclear astrophysical network calculations. According to the EXFOR database, the measurement precision for the Pr141(n,γ) cross section should be improved in the resolved and unresolved resonance region. The (n,γ) cross section of Pr141 was measured between 1 eV and 500 keV at the Back-n facility of the Chinese Spallation Neutron Source using the time-of-flight (TOF) method. The prompt γ rays were detected by four C6D6 liquid scintillator detectors, and the data was analyzed using the pulse-height weighting technique (PHWT). The majority of results are in agreement with the evaluated data libraries ENDF/B-VIII.0, JENDL-5.0, and TENDL-2021, with some significant exceptions for small resonances. The multilevel R-matrix Bayesian code sammy was used to extract the resonance parameters of Pr141 in the resolved resonance region. And the Maxwell average cross section (MACS) from kT=5 to 100 keV is calculated in the temperature range of the s-process nucleosynthesis model. In particular, at kT=30 keV the MACS value of Pr141 is 145.0±13.7 mb, which shows an obvious discrepancy with the Karlsruhe Astrophysical Database of Nucleosynthesis in Stars (KADoNiS) recommended value 111.4±1.4 mb.

β decay of proton-rich nuclei plays an important role in exploring isospin mixing. The β decay of P26 at the proton drip line is studied using double-sided silicon strip detectors operating in conjunction with high-purity germanium detectors. The T=2 isobaric analog state (IAS) at 13 055 keV and two new high-lying states at 13 380 and 11 912 keV in Si26 are unambiguously identified through β-delayed two-proton emission (β2p). Angular correlations of two protons emitted from Si26 excited states populated by P26 β decay are measured, which suggests that the two protons are emitted mainly sequentially. We report the first observation of a strongly isospin-mixed doublet that deexcites mainly via two-proton decay. The isospin mixing matrix element between the Si26 IAS and the nearby 13 380-keV state is determined to be 130(21) keV, and this result represents the strongest mixing, highest excitation energy, and largest level spacing of a doublet ever observed in β-decay experiments.

Compared with analog circuits, FPGA(Field Programmable Gate Array) had the advantages of redevelopment and low cost. Compared with MCU, FPGA used hardware description language to construct the circuit, which had the advantages of simple structure and fast parallel operation speed. In this paper, the simulation of digital Constant Fraction Timing can be realized based on FPGA, and the feasibility and accuracy of the design can be proved by using the simulation waveform of Modelsim and the waveform can be captured by signaltap. Modelsim can verify the correctness of the timing between modules, and signaltap can verify the actual running effect of the program on the board.

This work proposes a new fault diagnosis approach for a wind energy conversion (WEC) system. The proposed technique merges the benefits of feature extraction based on Gaussian Process Regression (GPR) and Multi-Class Random Forest (MCRF)-based fault classification where instances are classified into one or more classes. In the developed GPR-MCRF approach, the nonlinear statistical features including the mean vector M GPR and the variance matrix C GPR are computed using the GPR model with aim of extracting the most relevant features from the WEC system. Then, these features are introduced to the RF classifier for classification and diagnosis purposes. Therefore, the application of the GPR-MCRF technique for WEC systems aims to enhance the use of the classical raw data-based MCRF and diagnosis accuracy. Three kinds of faults (wear-out, open-circuit, and short-circuit faults) are considered in this work. Different case studies are investigated in order to illustrate the effectiveness and robustness of the developed technique compared to the state-of-the-art methods. The obtained results show that the the developed GPR-MCRF technique is an effective feature extraction and fault diagnosis technique for WEC systems.

Accurate wind speed prediction for each wind turbine is a critical basis of information for intelligent management and control of wind power system. How to precisely realize rapid prediction with small sample size is a critical open problem. This paper proposes an ultra-short-term wind speed prediction method based on meta learning algorithm with trend and fluctuation decomposition of wind speed signal. A meta learning prediction model with long short-term memory (LSTM) and recurrent neural network (RNN) is constructed as the base-learner, where low-frequency signal trend and high-frequency signal fluctuation are taken as the input of LSTM and RNN respectively. The forecasting results show that the mean absolute percentage error (MAPE) of the wind speed prediction scheme proposed in this paper is about 2.54%, and the sample size and training time costed in training are about 2.5% and 1.7% of traditional LSTM network. Results indicate that this method realizes ultra-short-term wind speed prediction with high accuracy as well as high efficiency.

Solitons, arising from nonlinear wave-matter interactions, stand out for their intrinsic stability during wave propagation and exceptional spectral characteristics1. Their applications span diverse physical systems, including telecommunications2, atomic clocks3,4, and precise measurements5,6. In recent years, significant strides have been made in developing cavity-optomechanics based approaches to generate optical frequency combs (FCs). In this study, we present an innovative approach, never explored before, that leverages elastomer membrane (EM)-cavity optomechanics to achieve the generation of soliton FCs, a highly sought-after phenomenon in the realm of nonlinear wave-matter interactions. Our method represents a significant breakthrough due to its streamlined simplicity, relying on a single continuous-wave (CW) laser pump and an externally applied acoustic wave exciting an EM-cavity, which gives rise to phonons, quantized vibrational energy states intrinsic to the elastomer's crystalline lattice structure. The mechanical resonator and electromagnetic cavity resonance are parametrically coupled within the microwave frequency range, collectively orchestrate the process of soliton FCs formation with remarkable efficiency. Numerical simulations and experimental observations demonstrate the emergence of multiple stable localized optomechanical wave packets, characterized by a narrow pulses time-domain response. Crucially, by setting the acoustic wave frequency to match the natural frequency of the EM resonator, the solitons' teeth are precisely spaced, and the EM's motion is significantly amplified, giving rise to a Kerr medium. The successful realization of optomechanical stable solitons represents a monumental advancement with transformative potential across various fields, including quantum computing and spectroscopy.

We develop a kinetic approach to the production of light nuclei up to mass number A⩽4 in intermediate-energy heavy-ion collisions by including them as dynamic degrees of freedom. The conversions between nucleons and light nuclei during the collisions are incorporated dynamically via the breakup of light nuclei by a nucleon and their reverse reactions. We also include the Mott effect on light nuclei; i.e., a light nucleus will no longer be bound if the phase-space density of its surrounding nucleons is too large. With this kinetic approach, we obtain a reasonable description of the measured yields of light nuclei in central Au+Au collisions at energies of 0.25AGeV–1.0AGeV by the FOPI Collaboration. Our study also indicates that the observed enhancement of the α-particle yield at low incident energies can be attributed to a weaker Mott effect on the α particle, which makes it more difficult to dissolve in nuclear medium, as a result of its much larger binding energy.
