Abstract
Stainless steel welds with a ferritic phase are extensively utilized in nuclear power plants. Spinodal decomposition stands as the primary factor contributing to the degradation of their service performance. Ion irradiation has been widely employed to investigate the damage behavior of materials. However, varying irradiation parameters, such as dose rate and implanted ions, are believed to result in significant differences in the extent of spinodal decomposition. In this paper, proton irradiation experiments were conducted at different dose rates on thermally aged EQ308L stainless steel welds. Spinodal decomposition within the ferrite at various radiation depths was compared and analyzed by using atom probe tomography to unveil the effects of dose rate and implanted hydrogen ions. The results reveal that, under conditions of high dose rate irradiation, spinodal decomposition can be partially alleviated when compared to the initial thermally aged state. Conversely, under low dose rate irradiation conditions, spinodal decomposition exhibits an enhancement trend. This difference may be attributed to the interplay between irradiation-enhanced diffusion and atomic mixing. Therefore, the dose rate significantly influences the progression of spinodal decomposition. Furthermore, implanted hydrogen ions may also inhibit spinodal decomposition within the ferrite, potentially by promoting the recombination of irradiation defects.
Molecular insights into the self-assembly of Janus nanoparticles obtained from coarse-grained molecular dynamics simulations
Authors: Wang Jiyu , Li Zhen 
Published: June 2024

Abstract
Grafting polymeric chains onto surfaces of nanoparticles generates amphiphilic Janus nanoparticles (JNPs) that can self-assemble into a variety of well-ordered and/or functional nanostructures. The self-assembly structures of JNPs can be designed by the manipulation of grafting schemes, but only if the self-assembly rule can be well understood. By using coarse-grained molecular dynamics (CGMD) simulations, we investigated the self-assembly process and morphology of triblock JNPs with varying chain lengths, chain ratios, and grafting topology. The HTH type of JNPs which possesses a middle hydrophobic block and two terminal hydrophilic blocks tends to aggregate into film structures via a shoulder-by-shoulder packing mode. The THT (Hydrophobic-Hydrophilic-Hydrophobic) type of JNPs is likely to form string structures via a head-to-head packing mode. The self-assembled film structures and string structures can be further regulated by the hydrophilic-hydrophobic chain ratio and length, forming rigid flakes, vesicles, porous structures, and so forth. Based on the molecular insights revealed by the example models, some plausible rules and strategies for tuning the self-assembly of nanoparticles are discussed in this paper. They are expected to facilitate future studies on the application of chemical self-assembly in materials science.

Abstract
Selective laser melting (SLM) can obtain metal magnetic materials with specific shapes and good mechanical properties, which has potential application value in the field of engineering. In this study, the soft-magnetic high-entropy alloy (HEA) Fe33Co28Ni28Ta5Al6 was prepared via SLM. The microstructure, mechanical, and magnetic properties of the sample are investigated. The sample consists of a single face-centered-cubic (FCC) phase. The tensile yield strength, ultimate tensile strength, and elongation of the sample are 752 MPa, 1067 MPa, and 27% respectively. Furthermore, the sample has a low coercivity of 970 A m−1, moderate saturation magnetization of 1.17 T, and high electrical resistivity of 121 μΩ cm. This work would provide a pathway for the rapid manufacturing high-performance soft-magnetic HEA.

Authors: Qi Lun , Yuan Le , Chen Sixuan , Zhu Qiyun , Wu Xueyu 
Published: June 2024

Abstract
The coatings (polysiloxane, flake aluminum, and glass powder) mechanical and infrared properties were analyzed in detail. The hardness, adhesion, surface roughness, SEM, and infrared thermal imager were used to evaluate the infrared radiation suppression and mechanical performance. The influences of coatings structure (pigment/adhesive ratio, function filler, and solvent content) on infrared emissivity were analyzed through theory and experiment. The coating hardness increased as the temperature increased due to the decomposition of the adhesive. The adhesion analysis showed an “M” type trend due to the functional powder and structure of the coating. Moreover, the coating infrared radiation suppression was also analyzed after thermal and chilling shock resistance.

Authors: Bi Shumin , Wang Faquan , Shi Dong , Wang Xiaoning , Jia Qingxiu 
Published: June 2024

Abstract
Flexible sensors are affected by various external factors during their use, such as water, thermal oxidation, and ultraviolet light, which causes a decrease in their sensitivity, but little research has been done in this area. This paper investigates the effects of washing, acid, ultraviolet, and thermal oxidation treatments on flexible sensors made of silver fiber fabrics, and the sensitivity and sensing performance before and after the treatments are compared. The findings show that the flexible sensor in use has a broad response range (0–70%) and strong stability (>1000 cycles). The sensitivity decreased significantly after washing, acid treatment, UV treatment, and thermal oxidation treatment but maintained good stability after 1000 tensile cycle tests.
Effect of Zr content on microstructure and mechanical properties of MoNbTaTiZrx refractory high-entropy alloy
Authors: Zhang Yanhui , Li Yuanhao 
Published: June 2024

Abstract
The purpose of this paper is to explore how Zr content affects the crystal structure, micro-morphology, and mechanical properties of (MoNbTaTi) 100-xZrx alloys (x = 5,15,25). The results reveal that with the varying Zr contents, the alloy changes from a single-phase solid solution structure of Zr5 to a solid solution structure of Zr15 and Zr25 with a double BCC phase. Higher Zr levels lead to more pronounced elemental segregation, particularly, which makes Zr element enriched in the interdendritic region, and with the increase of segregation degree, the second phase separates between dendrites. In other words, Zr and Ti elements are densely distributed in the BCC2 phase. With the formation of the BCC2 phase, the mechanical properties of the alloy also changed obviously. Notably, as the Zr content rises, the alloy’s hardness and strength improve, while its ductility initially decreases before subsequently increasing. The Zr15 alloy was in a transition period of a two-phase structure, and the two-phase structure was not stable at this time, which led to a decrease in the plasticity of the alloy. The yield strength of Zr25 alloy is 1595 Mpa, the Vickers hardness is 542 HV, and the compressive fracture strain is 29%, showing the best comprehensive properties.

Authors: Pan Ge , Zhang Miaomiao , Duan Qian 
Published: June 2024

Abstract
Cavities, commonly caused by bacteria metabolic acid in dental plaque, pose a prevalent dental problem. This study investigates the use of biocompatible zeolitic imidazolate framework 67 (ZIF-67) for cavities. ZIF-67 exhibits strong metal-binding properties and a large surface area. Streptococcus mutans (S. mutans) are responsible for dental plaque and cavities. In vitro studies have demonstrated that ZIF-67 could effectively inhibit S. mutans. Experimental evidence reveals that ZIF-67 can disrupt pathogen cell walls, resulting in leakage of DNA and RNA. Additionally, ZIF-67 inhibits biofilm formation on tooth surfaces without cytotoxicity on mammalian gingival fibroblast cells. These findings demonstrate the promising potential of ZIF-67 in preventing cavities and their biomedical applications.

Published: June 2024

Abstract
We have improved the gas chromatography (GC) method with the aid of 1H NMR to determine the degree of molar substitution (MS) of hydroxypropyl cellulose (HPC). This improvement relied on our established dissolution approach for low-substituted HPC, facilitating NMR determination and subsequently expanding the working range of the MS determination from the lower limit of USP specified as 53.4% to 9.3% (MS 0.2). In this method, 2-iodopropane was produced by the reaction of hydroiodic acid with HPC at high-temperature and then measured by GC. 1H NMR was used for the correction of GC method. The MS results via the GC method (MSGC) exhibited a linear correlation with those obtained by the 1H NMR method (MSNMR), with correction equation of MSNMR=1.8026MSGC - 0.2046 (R2 = 0.9979). Method validation results showed that the average recovery and relative standard deviation (RSD) of MS are 103.5% and 0.83%, respectively. Detection limit and quantitation limit were 0.08 and 0.26, respectively. This method is accurate, sensitive with good precision, which is of great value for the production, research and development, and application of HPC, particularly the low-substituted HPC.

Abstract
ptical cross-talk is a critical characteristic of Silicon
Photomultipliers (SiPMs) and represents a significant source of the
excess noise factor, exerting a substantial influence on detector
performance. During the avalanche process of SiPMs, photons
generated can give rise to both internal cross-talk within the same
SiPM and external cross-talk when photons escape from one SiPM and
trigger avalanches in others. In scenarios where SiPMs are arranged
in a compact configuration and positioned facing each other, the
external cross-talk could even dominate the cross-talk
phenomenon. This paper investigates two distinct methods for
measuring external cross-talk: the counting method, which involves
operating SiPMs face-to-face and measuring their coincident signals,
and the reflection method, which employs a highly reflective film
attached to the surface of the SiPMs. External cross-talk
measurements have been conducted on several types of SiPMs,
including Vacuum Ultra-Violet (VUV) sensitive SiPMs that Fondazione
Bruno Kessler (FBK) and Hamamatsu Photonics Inc (HPK) produced for
nEXO as well as visible-sensitive SiPMs provided by FBK, HPK and
SensL Technologies Ltd (SenSL) for JUNO-TAO. The results reveal a
significant presence of external cross-talk in all tested SiPMs,
with HPK's SiPMs exhibiting a dominant external cross-talk component
due to the implementation of optical trenches that effectively
suppress internal cross-talk. Furthermore, we found that the number
of fired SPADs resulting from internal cross-talk can be described
by combining Geometric and Borel models for all tested SiPMs, while
the external cross-talk can be predicted using a pure Borel
model. These distinct probability distributions lead to different
excess noise factors, thereby impacting the detector performance in
varying ways.
Cone-beam computed laminography with anisotropic adaptive weighted total variation minimization based on the framework of the Chambolle-Pock algorithm
Authors: Tang Haowei , Liu Yi , Zhang Pengcheng , Li Shu , Liu Yu , Gui Zhiguo 
Published: June 2024

Abstract
Cone-beam computed laminography (CL) is still a very
challenging problem for the inspection of thin-plate objects. Since
CL projections are incomplete, the reconstructed images always
suffer from severe aliasing and blurring in the z direction. To
mitigate this problem, we propose an anisotropic adaptive weighted
total variation (AAwTV) reconstruction model, which takes the edge
properties between adjacent voxels into account and introduces
different weights in different directions. In addition, we solved
the proposed AAwTV using the Chambolle-Pock (CP) framework, since it
has good computational efficiency and stable convergence, and is
often easy to get a satisfactory reconstruction result. Experiments
on simulated PCB phantom and simulated workpiece phantom show that
the proposed algorithm can preserve the detailed features of the
object well, and can effectively suppress inter-slice aliasing and
blurring.

Published: June 2024

Abstract
We present the design of a Fourier-transform spectrometer (FTS) tailored for operation within the frequency range of 75 GHz to 300 GHz, offering a spectral resolution surpassing 2 GHz. This FTS can be used for characterizing detectors on a Cosmic Microwave Background (CMB) Polarization Telescope for the observation of CMB B-mode polarization. The FTS instrument is divided into the primary part, housing a Martin-Puplett interferometer (MPI) module, and the coupled part, which incorporates a beam expanding module and a beam steering module. An in-depth performance analysis focusing on the MPI module, involving considerations such as the orientation of the beam splitter, dihedral angle of the roof-top mirrors, and positioning uncertainty of the scanning mirror, has been conducted by using a simulation tool. Results indicate that the spectral characteristic remains unaffected by variations in the Reflection/Transmission ratio of the beam splitter, with any deviation from the 1:1 ratio uniformly decreasing intensity. The impact of dihedral angle errors of roof-top mirrors (below 0.02 degrees) and positioning uncertainty in the scanning mirror (lower than 3 × 10-3 mm) on the system performance is acceptable for the design of the FTS. The beam expanding module is capable of enlarging the output beam of the MPI module to roughly a 150 mm-radius. The beam steering module allows for directional adjustments within the range of +17 degrees to -17 degrees relative to the normal of the target plane. Preliminary testing on the MPI prototype reveals a spectral resolution of 1.5 GHz for the measured frequency.

Abstract
Precision measurements of properties of the Higgs, W and Z bosons are the key scientific goals at future e
+
e
- Higgs factories. A main challenge for these goals is to fulfill an unprecedented jet energy resolution, and the design of the hadronic calorimeter (HCAL) is found to be one of the most important factors. The conceptual design of high-granularity glass scintillator hadronic calorimeter (GSHCAL) has been proposed recently, which can achieve a Boson Mass Resolution (BMR) of around 3.38% with an initial parameter configuration and show great potential to significantly increase the sensitivities to the most physics measurements at future e^+e^- colliders. Nevertheless, more studies on the design optimization of the GSHCAL are necessary to balance the key physics performance (i.e. the BMR) and the cost, as well as the engineering complexity. In this paper, the optimizations for several key parameters of the GSHCAL are discussed and different GSHCAL configurations are compared, which provide an important reference for the GSHCAL design. Besides, the R&D progress of high-performance and large-area glass scintillators is also introduced.

Abstract
Myristicin is the main compound in nutmeg oil which has potential as an antioxidant, anti-inflammatory and antiproliferative. Miristicin can be obtained through the fractionation distillation process. Fractionated distillation generally requires very high columns to get better results. Spinning band distillation is one of the separation methods built on the principle of simple fractionated distillation with further improved processing efficiency. The purpose of this study was to examine the effect of fractionated temperature on the yield and content of myristicin. This experiment used a pressure of 15 mmHg, a reflux ratio of 5:1, and an equilibration time of 10 minutes. This study used 3 types of experiments with the treatment of differences in fractionated temperature ranges. Each experiment was divided into 4 fractions with different temperature ranges. The results showed that myristicin evaporates at temperatures above 230 °C (AET). The fractionation process under suitable operating conditions can result in high yields and concentrations of myristicin.
