A miniaturized sensing system for liquid level and concentration based on piezoelectric micromachined ultrasonic transducers

This paper presents a system utilizing scandium-doped aluminum nitride (ScAlN) piezoelectric micromachined ultrasonic transducers (PMUTs) for simultaneous detection of liquid level and concentration. The PMUTs comprise a grid of 13×13 square units, covering an area of 2.8×2.8 mm2 in total. The PMUTs exhibit a resonant frequency of approximately 1 MHz in water and a beam angle of 30.16°, providing excellent sound field directivity. Additionally, a custom package housing with a cantilever baffle is designed to measure sound velocity in real time without modifying the container's structure. Finally, the fabricated PMUTs transceiver is combined with the TDC1000 ultrasonic sensing analog front-end to produce a high-precision liquid level and concentration detector. Glycerol and NaCl solutions are used as test samples. The system demonstrates measurement errors of ±0.5 % / ±1.1 % and ±0.5 mm / ±0.5 mm for concentration and liquid level, respectively, with resolutions of 0.323 % / 0.914 % and 0.077 mm / 0.070 mm. Compared with the related work results, the system based on PMUTs demonstrates advantages in miniaturization and high precision, making it particularly suitable for small-volume fluid containers, where sensor size and detection precision are crucial.

Designs of ultra-HPHT Electrical Component Packages for Downhole and Geothermal Wellbore Logging Tool Integrations

Conventional dielectric sealing materials (PEEK, glass and glass-ceramic) used for sealing electrical feedthroughs, connectors, interconnectors and bulkheads in electronic packages can provide reliable downhole wellbore long-term logging tool service up to 150C or short-term logging service for greater than/equal 200C, due primarily to low glass transition temperature of the used sealing materials. This paper will demonstrate that the maximum allowable operating pressure and temperature could be from 20KSI to 100KSI and from 200C to 400C with Borosilicate and Bismuth-Boron-Silica (XTS) sealing glasses. Borosilicate glass sealed Inconel-Kovar/Kovar electronic housing could maintain reliability up to the maximum pressures of ~35KSI at 200C or 25KSI at 400C. Similarly, a Bismuth-Boron-Silica XTS glass sealed stainless steel electronic package housing could have a maximum operating pressure of ~100KSI at 150C or ~50KSI at 300C temperature. It has been found that high glass transition temperatures of (440-560)C for Borosilicate glass and (44010)C for Bismuth-Boron-Silicate (XTS) glass are key for making highly reliable ultra-HPHT electronic component packages. It is shown that the tetrahedral diamond-like microstructures of these sealing glasses are keys to ensure water-repelling properties to maintain sufficient electrical insulation resistance regardless of their use in water or moisture-rich wellbores. Moreover, compressive pin stress is found to be additional key for mitigate frequently observed glass seal cracks during logging tool field services.

A Resonant Differential Pressure Microsensor With Stress Isolation and Au-Au Bonding in Packaging

Resonant differential pressure (DP) sensors are prone to environmental disturbances [e.g., temperatures ( <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> <tex-math notation="LaTeX">${T}$ </tex-math></inline-formula> ) and static pressure (SP)] due to poor packaging. In order to address this issue, this article presents a resonant DP microsensor where the core pressure-sensitive element was assembled with the packaging house using stress isolation and Au–Au bonding. The stress isolation was used to reduce the effect of packaging house on the core-sensitive element when the environmental disturbances of temperature and SP varied, and the Au–Au bonding was used to improve the structural stability to reduce the frequency drift over time. Numerical simulation was conducted to confirm the positive effect of including the stress isolation structure and fabrication processes were developed to realize Au–Au bonding in packaging. Experimental characterization was conducted, reporting reductions of three times in temperature disturbance, 25 times in SP disturbance, and 35 times in frequency drift in comparison with the counterpart without stress isolation and Au–Au bonding. Based on these improvements, the accuracy of the developed resonant DP microsensor was quantified as 0.03%FS within the DP of 0–100 kPa, the temperature of −10 °C to 60 °C, and the SP of 110–200 kPa.

The Role Of Muslim Entrepreneurs In The Coal Weaving Industry During Pandemic Based On Local Wisdom

The Role of Muslim Entrepreneurs in the Coal Weaving Industry Based on Local Wisdom shows that the role of Muslim entrepreneurs has contributed to the surrounding community as evidenced by the increasing number of workers or weaving craftsmen, where in the past the community was known as the lazy Malay myth which is a construction of negative cultural habits attach)ed to Malay self.

Detection of necrotrophic DNA marker of anthracnose causing Colletotrichum gloeosporioides fungi in harvested produce using surface plasmon resonance

Agriculture and food crops monitoring is extremely important for securing the food supply chain to human society. Here, we developed a highly specific detection method for monitoring pathogenic fungus Colletotrichum gloeosporioides using necrotrophic DNA biomarker as the recognition element and surface plasmon resonance (SPR) as transducing mechanism in the prism coupling configuration. The sensor shows its response for a wide range of concentrations from pM to μM of target DNA sequence using a complementary DNA probe immobilized on the sensor surface, which could detect concentrations as low as 7 pM. The detection limit is found to be comparable with conventional molecular-based detection platforms, achieved due to optimized spectral SPR bimetallic substrate with subpixel resolution obtained by post processing. The response time of the sensor for detection is less than 30 min at room temperature. The quick detection scheme of the sensor may facilitate the screening of a large number of samples acquired for the sorting of harvested produce. This sensor is fast, reliable, cost-effective, and can be miniaturized for portability for the screening of real samples (mRNA) in the field and packaging house.

Versatile TIM Solution with Chain Network Solder Composite

ABSTRACT A novel epoxy-based SAC solder paste TIM system has been developed with the use of non-volatile epoxy flux. Cu filler was added to the solder paste, with Cu volume % of metal ranged from 17 to 60 volume % of metal. Formation of semi-continuous high melting Cu chain network was achieved, with Cu particles bridged by the CuSn IMC. This chain network, at sufficient concentration, serves as skeleton and maintains the shape of the sandwiched solder paste layer, thus prevents further spread out at subsequent SMT reflow process, and also allowed formation of TIM joint even in the absence of solderable metallization on flip chip and packaging housing. This chain network hampered the flow of liquid solder, thus restrained the expansion of outgassing, and consequently resulted in low voiding. Existence of crevices was attributed to excessive oxide brought in by Cu particles, and appeared to increase with increasing Cu filler content. Presence of ductile solder within TIM joint promises high resistance against brittle cracking under stress. The Cu content could be further optimized between 17 and 33 volume % of metal to avoid flux bleeding and maintain good epoxy adhesion between TIM phase and parts. The 20°C thermal conductivity achieved was 6.1 W/mK, and could be up to about 13 W/mK with further epoxy flux optimization.

Bio-Based Poly(butylene succinate)/Microcrystalline Cellulose/Nanofibrillated Cellulose-Based Sustainable Polymer Composites: Thermo-Mechanical and Biodegradation Studies.

Biodegradable polymer composites from renewable resources are the next-generation of wood-like materials and are crucial for the development of various industries to meet sustainability goals. Functional applications like packaging, medicine, automotive, construction and sustainable housing are just some that would greatly benefit. Some of the existing industries, like wood plastic composites, already encompass given examples but are dominated by fossil-based polymers that are unsustainable. Thus, there is a background to bring a new perspective approach for the combination of microcrystalline cellulose (MCC) and nanofibrillated cellulose (NFC) fillers in bio-based poly (butylene succinate) matrix (PBS). MCC, NFC and MCC/NFC filler total loading at 40 wt % was used to obtain more insights for wood-like composite applications. The ability to tailor the biodegradable characteristics and the mechanical properties of PBS composites is indispensable for extended applications. Five compositions have been prepared with MCC and NFC fillers using melt blending approach. Young’s modulus in tensile test mode and storage modulus at 20 °C in thermo-mechanical analysis have increased about two-fold. Thermal degradation temperature was increased by approximately 60 °C compared to MCC and NFC. Additionally, to estimate the compatibility of the components and morphology of the composite’s SEM analysis was performed for fractured surfaces. The contact angle measurements testified the developed matrix interphase. Differential scanning calorimetry evidenced the trans-crystallization of the polymer after filler incorporation; the crystallization temperature shifted to the higher temperature region. The MCC has a stronger effect on the crystallinity degree than NFC filler. PBS disintegrated under composting conditions in a period of 75 days. The NFC/MCC addition facilitated the specimens’ decomposition rate up to 60 days

It has the advantages of laser capping, low expansion, high thermal conductivity and high reliability, and can meet the requirements of spaceborne power module packaging applications.

Glass Optical Connector Ferrule for Solder-Reflow-Compatible Photonic IC Edge Interconnections

A glass-tube-based MT-style fiber array ferrule is presented that provides a compact interface to PIC (Photonic Integrated Circuit) edge waveguides. The approach aligns and attaches a glass ferrule on the PIC substrate top surface using solder-reflow-resistant UV curable adhesives. A mating fiber array connector ferrule is attached to the PIC after solder reflow. Mate/demate experiments on pairs of matching glass-based connector ferrules demonstrated IL (insertion loss) values across eight single mode fiber array channels of less than 1.5 dB without using index matching fluid between coupled arrays. A compact connector packaging housing compatible with glass tube-based ferrules is also presented.

Effectiveness of Chemical and Thermal Treatments on Control Rhizopus Stolonifer Fruit Infection Comparing Tomato Cultivars with Different Sensitivities to Cracking.

Tomatoes are among the most important horticultural crops; however, it is estimated that 30% of tomato yield is lost due to postharvest rot due to Rhizopus stolonifer, a fungus which requires lesions to initiate the infectious process. Tomato fruit cracking is a physiopathy which causes significant economic losses, since cracking is the door used by the fungus. In this experiment, 14 cultivars of tomato of different types were used. Fruit sampling was carried out in the middle of the crop cycle, coinciding with the peak of yield; then, the fruits were divided into two groups: one group was inoculated with Rhizopus in order to assess the effectiveness of washing, whilst the other was treated with sterile water. The fruits of each group were divided into lots to be treated with six washing treatments: dipping in hot water at 20, 40 and 60 °C for 20 s; the fruits were then sprayed with the following solutions: 0.6% of Hydrogen Peroxide 23% + Peracetic acid 15%; commercial bleach at 0.5% and 2% of Hydrogen Peroxide 50%. The control sample was not washed. The results show that there was an influence of cultivar on fruit cracking, which was strongly related with Rhizopus infection. Three cultivars were not susceptible to cracking, and therefore, were not sensitive to Rhizopus infection. The effectiveness of different washing treatments of tomato fruits depends on several factors; nonetheless, hot water treatment has been shown to be more effective than the use of chemical products such as commercial bleach or hydrogen peroxide. Another factor, the susceptibility of cultivars to cracking, determines the effectiveness of the washing treatment. The results provide an important basis for making decisions about the washing management of tomato fruits in packaging houses.
