Effect of Graphene Oxide-Based Nanodielectric on Electrical Discharge Machining Performance of Ti-6Al-4 V.

Graphene oxide (GO), a two-dimensional nanomaterial, exhibits exceptional electrical and thermal conductivity as well as outstanding tensile strength. In this study, GO nanosheets were dispersed into the dielectric fluid during electrical discharge machining (EDM) of Ti-6Al-4V alloy using copper electrodes, enabling a comprehensive evaluation of the modified dielectric's behavior and the alloy's impact on machining performance. The incorporation of GO significantly influenced both the material removal rate (MRR) and the electrode wear ratio (EWR).

Arsenic-free Ge-Te-based ovonic threshold switching material with reduced leakage current.

There is growing interest in next-generation semiconductor memory that combines high speed, large capacity, and non-volatility. Many types of emerging memory technologies, such as PCRAM and MRAM, are being developed utilizing 3D crossbar array structures to achieve high integration. In this type of structure, selectors are essential for blocking sneak current that bypasses cells during read operations.

All Roads Lead to Rome: Achieving 3D Object Encryption Through 2D Image Encryption Methods.

In this paper, we explore a new road for format-compatible 3D object encryption by proposing a novel mechanism of leveraging 2D image encryption methods. It alleviates the difficulty of designing 3D object encryption schemes coming from the intrinsic intricacy of the data structure, and implements the flexible and diverse 3D object encryption designs. First, turning complexity into simplicity, the vertex values, real numbers with continuous values, are converted into integers ranging from 0 to 255.

Non-Structural Protein V of Canine Distemper Virus Induces Autophagy via PI3K/AKT/mTOR Pathway to Facilitate Viral Replication.

Canine distemper (CD) is a highly infectious disease of dogs which is caused by canine distemper virus (CDV). Previous studies have demonstrated that CDV infection can induce autophagy in cells. However, the mechanism underlying CDV-induced autophagy remains not fully understood.

Tribological and Heat Transfer Investigation of Graphene Oxide Coatings on Nylon Rotating Bands in an Artillery System.

Exploring ways to improve the performance of rotating bands is of great importance for enhancing the power of modern artillery. This study prepared graphene oxide-coated Nylon (GO-Nylon) and Nylon samples based on nylon rotating bands in artillery systems to investigate the feasibility of introducing GO-coated nylon rotating band materials to enhance their tribological and thermal properties. The friction behavior and thermal effects of these two surfaces were analyzed under different external loads and surface roughness conditions.

Psychosomatic health status and corresponding comorbid network analysis of college students in traditional Chinese medicine schools.

Introduction: Depression, anxiety, and somatic symptoms are highly comorbid and represent the most prevalent psychosomatic health issues. Few studies have investigated the network structure of psychosomatic symptoms among traditional Chinese medicine (TCM) students. This study aims to investigate the psychosomatic health status of college students in TCM universities, while simultaneously constructing a network structure of common somatic symptoms and psychological symptoms.

An amorphous CrGeTe/polyimide double-layer foil with an extraordinarily outstanding strain sensing ability.

To realize a wearable health monitoring system, a piezoresistive material capable of detecting very small mechanical strains is needed. In this study, an amorphous CrGeTe thin film was deposited on a polyimide film by sputtering, and the piezoresistive properties were investigated. In experiments, the CrGeTe/polyimide double-layer foil exhibited an outstanding piezoresistive performance as evidenced by the appearance of self-healing cracks during tensile tests and a remarkably large gauge factor of 60 000 in resistance change measurements.

Research Note: Integrative analysis of transcriptome and gut microbiome reveals foie gras capacity difference between cage and floor rearing systems.

To explore the differences in foie gras performance between geese raised in cages and on the ground, we conducted an integrative analysis of liver transcriptome and gut microbial metagenomes. The results showed extremely significant differences in the liver weight (P < 0.01) and liver lipid accumulation of FRS and CRS groups.

Prediction of Residual Life of In-Service P91 Steel Joints Based on Fracture Behavior.

P91 steel and P91 steel joints experience performance degradation after serving for 30,000 h in working conditions. To clarify the damage and failure behavior and remaining life of the joints during subsequent service, further creep testing was conducted on the welded joints of P91 steel that had been in service for 30,000 h at three temperatures: 550 °C, 575 °C, and 600 °C. The fracture surface and the cross-section damage behavior were characterized by SEM and EBSD methods.

Study of Fatigue Crack Initiation and the Propagation Mechanism Induced by Pores in a Powder Metallurgy Nickel-Based FGH96 Superalloy.

Thermally induced pores (TIPs) are generally the source of fatigue crack initiation in the powder metallurgy (PM) Ni-based FGH96 superalloy. The effect of TIPs on fatigue crack initiation on the surface of the FGH96 superalloy was detected using scanning electron microscopy (SEM). The cause of fatigue crack deflection was studied using electron backscatter diffraction (EBSD) analysis.

Removal of Zn(II) by magnetic composite adsorbent: synthesis, performance, and mechanism.

In this study, L-methionine and nano-FeO were encapsulated and cured on sodium alginate by the ionic cross-linking method to form magnetic composite gel spheres (SML) as an adsorbent for the removal of Zn(II) from water. The influence of adsorbent dosages, pH, reaction time, and initial ion concentration on the ability of the gel spheres to adsorb Zn(II) was investigated, and the adsorption mechanism was identified. The experimental results showed that under the optimum conditions (pH = 5, t = 60 min, dosage of SML is 0.
