Inertia diaphragm pressure transducer [PDF]

, 1971
Transducer measures gas pressure profiles in high temperature, short duration, gas flows usually found in devices where pressure pulses may have durations of few microseconds to several milliseconds. Assembly includes fluid delay line, delay chamber, and

Study on the Effect of Cracks in Diaphragm Couplings on the Dynamic Characteristics of Shaft System

Machines
Diaphragm couplings are prone to developing diaphragm cracks under prolonged high-speed operating conditions, which can lead to degradation in the performance of the transmission system and affect the dynamics of the shafting system.

Developmental Hypoxia Enhances Kidney Organoid Complexity and Maturity

Advanced Science, EarlyView.
The current bottleneck in metanephric mesenchyme (MM)‐derived nephron organoid development is the absence of a connected network of collecting ducts (CD) derived from the ureteric bud (UB). To address this limitation, this study proposes a hypoxia‐based differentiation method that mimics the natural renal developmental environment, enabling the ...

Confocal Absorbance‐Activated Droplet Sorting (cAADS) for Enzyme Engineering

Advanced Science, EarlyView.
A custom confocal absorbance‐activated droplet sorting (cAADS) platform is presented, which confines illumination and detection to a small area on the “droplet plane”, enabling enhanced sensitivity at ultrahigh throughput. System performances and versatility are demonstrated by screening Bilirubin Oxidase encapsulated in 10 pL droplets at 5.4 kHz ...

Sustainable and Direct Upcycling of Waste Graphite Anodes via Deep Eutectic Solvents

Advanced Science, EarlyView.
A charged particle attacks the vacancy to realize the in‐situ P‐doping model. Cl− anions chelate with charged metal ions for the purpose of impurity removal, and meanwhile the cations bind to the electrons on the vacancy surface to neutralize the electrons.

Dnmt1 Alleviates S1PR1‐Mediated Pyroptosis after Spinal Cord Injury through Regulating Pon3 Expression

Advanced Science, EarlyView.
This study systematically explores the action mechanism of Pon3 and its regulatory targets in spinal cord injury (SCI). It demonstrates that Dnmt1 regulates Pon3 expression by modulating methylation levels, thereby inhibiting S1PR1‐mediated pyroptosis and improving SCI prognosis.

Loss of Hepatic Angiotensinogen Attenuates Diastolic Dysfunction in Heart Failure with Preserved Ejection Fraction

Advanced Science, EarlyView.
Increased hepatic angiotensinogen (AGT) abundance leads to cardiac diastolic dysfunction via the AngII‐independent pathway. Liver‐derived AGT is internalized by LRP2 in cardiac endothelial cells, subsequently contributing to myocardial diastolic dysfunction by suppressing microvascular angiogenesis via inhibiting the GATA2/Pim3 pathway.
