The bonding process is a critical step in the synthesis of face-to-face interlaced carbon nanotubes. Copper-copper bonding has emerged as a promising alternative to traditional silicon dioxide to silicon dioxide bonding due to its advantages, including a reduced bonding area requirement and greater flexibility in chip-to-chip bonding. However, the use of formic acid in copper-copper bonding can adversely affect the catalyst employed in carbon nanotube synthesis. This paper presents a modified technique for achieving high-quality Cu-Cu bonding without the need for formic acid. We introduce the innovative use of pillar-cavity pairs, designed to increase contact pressure at the Cu-Cu interface during the bonding process. Additionally, a copper base is employed to enhance the adhesion strength between the electroplated copper pillars and the substrate. Our experimental results demonstrate that the bonded chips can withstand subsequent processes, including double-side-dicing and high-temperature treatments, highlighting the robustness of this bonding approach. The bonding strength is quantitatively evaluated through shear tests, confirming the reliability and stability of the Cu-Cu bonds formed using this technique. This technology exhibits promising potential for use in the future synthesis of face-to-face interlaced carbon nanotubes. © 2023 IEEE.

In recent days, many people die of pulmonary embolism (PE) complications, respiratory problems that form in the deep lung. Covid-19 is the leading cause of preventable hospital death for trauma patients and despite 0.1% of the population receiving a new diagnosis annually. developing computer-aided detection (CAd) systems would alleviate these concerns; however, current systems classify computed tomography (CT) slices individually and yield many false positives from Covid-19. We have done a retrospective study on a dataset collected from various health central hospitals. There is a continued need for tools that can predict Covid and black fungal in hospitalized patients. It affects an estimated 3000–6000 Individuals just in recent days. This can cause considerable morbidity and mortality. For segmentation and classification, we mortality. For segmentation and classification, we use a 2d dense-Net. By developing more effective detection algorithms, we hope to ensure a more frequent and accurate diagnosis of covid, thereby reducing its high mortality rate. reports have shown that black fungus is steadily increasing in India as well as the death toll it causes. It has been called ‘a pandemic within the Covid-19 pandemic’ by medical specialists. Black fungus, or Mucormycosis, is a complication caused by a fungal infection. In India Mucormycosis has been detected in Karnataka, Uttarakhand, Telangana, Madhya Pradesh, Andhra Pradesh, Haryana, and Bihar, Primarily, fungal spores floating in the environment gives people this infection. This spreads through contact. The fungi sticks to a body part and travels inside through the nose, lungs or sinus.

We demonstrate use of mechanistic modeling assisted designing of scalable and efficient continuous multicolumn radial Protein A chromatography based purification step for biosimilar monoclonal antibody therapeutic. Protein A chromatography using continuous multicolumn chromatography has several benefits, including reduced buffer use, increased productivity, and small footprint. Productivity and capacity utilization (CU) of the continuous radial CaptureSMB process under varying operating conditions was predicted using the general rate mechanistic model framework and validated with the experimental results. Effect of critical process parameters like mAb feed concentration (c0), loading breakthrough % (s), and residence time (rT) on productivity and capacity utilization of radial flow continuous Protein A chromatography were evaluated. Model predictions were validated using the experimental results proving the reliability and feasibility of the modeling approach. At 3.00±0.20 mg/mL feed model mAb concentration, the model-based approach predicts 20.33 g/L/h productivity (rT= 2 minute, s=80%) using MabSelect™ PrismA resin. By conducting the continuous CaptureSMB experiment under the same operating conditions, this productivity forecast was verified experimentally and found to be 20.45 g/L/h. The results demonstrate the use of mechanistic modeling framework to predict the performance of continuous radial flow CaptureSMB chromatography for biosimilar monoclonal antibody therapeutic purification. © 2024, The Authors.

The integration of hardware and software, specifically the Guidance and Navigation Control (GNC) system, is cru-cial for achieving underwater positioning in autonomous systems like Autonomous Underwater Vehicles (AUVs). In our study, we present a novel Hardware-in-the-Loop System (HILS) framework that differs from traditional component-based approaches. This framework enables real-time interaction with the GNC loop, incorporates GPS simulation to enhance navigation accuracy, and utilizes an inertial measurement unit(IMU) and a Flight Motion Simulator (FMS) to capture real-time attitude dynamics. By connecting to a real-Time Computer, it effectively communicates with the AUV's GNC loop, taking into consideration actuator latency. Our experiments demonstrate the system's precision and dependability, establishing it as an innovative tool for AUV research and setting a precedent for future advancements.

In this paper, a method for designing and fabricating an autonomous underwater vehicle (AUV) with a dual Acoustic Communication Modem is presented. The aim is to ensure reli-able communication in challenging underwater environments. To achieve this, the AUV incorporates two underwater communication modems that use the FKS-FH and PSK-OFdM methods. The proposed AUV also includes a combined inertial measurement unit (IMU) and doppler velocity log (dVL) navigation system, as well as a non-linear controller. These features enable stable navigation and the collection of topographical information from the seabed. real-world sea trials were conducted to validate the AUV's performance in terms of precise control, stability, underwater communication, and navigation. The success rate and maximum communication distance of the underwater communication system were calculated. Furthermore, real-field tests were carried out to confirm the system's reliable underwater commu-nication and navigation capabilities. The successful integration of advanced navigation systems and underwater communication technologies into the AUV demonstrates its potential for complex marine tasks and operations.

Extreme ultraviolet (EUV) scatterometry is an increasingly important metrology that can measure critical parameters of periodic nanostructured materials in a fast, accurate, and repeatable manner and with high sensitivity to nanoscale structure and material composition. Because of this, EUV scatterometry could support manufacturing of semiconductor devices or polymer metamaterials, addressing the limitations of traditional imaging methods such as resolution and field of view, sample damage, throughput, or low sensitivity. Here we use EUV scatterometry to measure the profile of an industrially relevant 2d periodic interconnect structure, using λ = 29 nm light from a table-top high harmonic generation source. We show that EUV scatterometry is sensitive to out-of-plane features with single-nanometer sensitivity. Furthermore, we also apply a methodology based on the Fisher information matrix to optimize experimental design parameters, such as incidence angles and wavelength, to show how measurement sensitivity can be maximized. This methodology reveals the strong dependence of measurement sensitivity on both incidence angle and wavelength — even in a simple two-parameter case. Through a simultaneous optimization of incidence angles and wavelength, we determine that the most sensitive measurement of the quantities of interest can be made at a wavelength of ∼14 nm. In the future, by reducing sample contamination due to sample preparation, deep sub-nanometer sensitivity to axial profiles and 2d structures will be possible. Our results are an important step in guiding EUV scatterometry towards increased accuracy and throughput with a priori computations and by leveraging new experimental capabilities. © 2025, CC BY.

The present work proposes to emphasize the effects of friction and wear formulations for wear prediction for turning operations. It is shown that friction models play a major role on local variables such as pressure, sliding speed and temperature (σn, Vsl, T) and thus on the simulated tool wear. This work highlights that both formulations and parameters of these equations should be carefully considered to achieve an actual predictive capability. © 2022 Trans Tech Publications Ltd, Switzerland.

Ltd. Xing Xian County Economic and Technological Development Zone Lvliang035300 China Taiyuan University of Technology China

The effect of temperature and humidity alternation on the corrosion behavior and mechanical properties of 6061 aluminum alloy in a simulated urban industrial atmospheric environment was investigated and analyzed by weightlessness method, scanning electron microscope (SEM), energy dispersive spectrometer (EdS), Fourier infrared spectroscopy (FT-Ir), X-ray diffraction (Xrd), and dynamic potential polarization (LSV). The fluctuation of the composition, structure and morphology of the corrosion product layer are studied, the entry of corrosive medium destroy the densification and the second phase bring the potential difference, which causes the corrosion to expand internally and accelerates the localized corrosion. The corrosion rate shows a trend of first gradually increasing and then decreasing, corresponding to the formation of the initial oxide film hinders the corrosion, and then the local product film separation leads to the weakening of the corrosion resistance. The mechanical properties are significantly reduced after corrosion, and the fracture mechanism is transformed from the ductile fracture to the cleavage fracture gradually. © 2024, The Authors.

Lost circulation in fractured formations is a worldwide problem experienced in drilling engineering characterized by low plugging efficiency and poor plugging effect. Adhesive materials are introduced to solve the problems of poor self-adaptation of the conventional composite bridging plugging systems in fractured formations and repeated lost circulation caused by pressure fluctuations. In this study, based on visualization, as well as thermogravimetric, dynamic thermomechanical, and particle-size analyses, the viscoelasticity, high-temperature stability, and glass transition characteristics of the adhesive ethylene vinyl acetate (EVA) particles are assessed. The adhesion state of the materials is clarified at specific temperatures, and pressure-bearing experiments are conducted to optimize the formula for lost circulation control. The plugging effect of the conventional composite bridging plugging system is compared with that of the proposed system to reveal the optimal dosages of the adhesive material and the mechanisms of action. The experimental results reveal that the adhesive EVA particles have good thermal stability (thermally decomposes after 374 °C) and viscoelasticity. A simulation experiment involving plugging a 2-mm fracture using the adhesive composite bridging plugging system reveals that the pressure-bearing capacity is 12 MPa, the cumulative filtration loss is only 50mL, and the plugging performance is excellent. We inferred that the surface of the adhesive material softened at a specific temperature and possessed strong viscoelasticity, which strengthened the bridging, filling, and twisting of the conventional composite bridging plugging system and increased coherence with the fracture channel surface and increased stationary capacity. The plugging is synergistic, the plugging zone is strengthened, and the success rate of primary plugging is improved. © 2024, The Authors. All rights reserved.
