A Low‐Power Radioisotope XRF Spectrometer for Detection of Light Elements on Planetary Missions

X-Ray Spectrometry, EarlyView.
ABSTRACT Current X‐ray spectrometers for in situ geochemical analysis on planetary missions typically rely either on X‐ray tubes, which demand electrical power and add mass and thermal complexity, or on alpha particle X‐ray spectrometers (APXS) that use rare 244Cm$$ {}^{244}\mathrm{Cm} $$ sources, and come with severe concerns on radiation safety and ...

Potentiometric Determination of Betahistine in Pharmaceutical Formulations by Drug Selective Sensors

International Journal of Electrochemical Science, 2015
Betahistine is histamine like drug that acts as both a partial histamine H1 receptor agonist and as a histamine H3 receptor antagonist. This research introduces design and construction of a PVC membrane sensor and nano-composite carbon paste electrode ...

Pressure Pulses Generated by Wire‐Guided Discharges in Water

High Voltage, EarlyView.
ABSTRACT The hydrodynamic characteristics of underwater wire‐guided discharges and their relationships with the wire length and pulsed circuit parameters are not fully understood. In this paper wire‐guided discharges using wires of length 3, 5 and 7 cm and diameter of 0.05 mm have been investigated. The energy available to the discharges was 162.3 J at

All-solid-state poly (vinyl chloride) membrane thiocyanate–selective potentiometric electrode

Journal of New Results in Science, 2021
A novel all-solid-state contact poly (vinyl chloride) (PVC) membrane–containing thiocyanate-selective electrode has been prepared. The electrode exhibits the best performance with a membrane composition of PVC:BEHS:ionophore:KTpClPB of 33.0:64.0:2.0:1.0 (

Degradation of PVC Waterproofing Membrane containing Plasticizers

IOP Conference Series: Materials Science and Engineering, 2020
Abstract Durability and repairability are one of the basic conditions for the economically efficient use of building materials. The actual lifetime of PVC waterproofing membrane is not only affected by the ageing of the materials, but also by the ageing of the joints.

Rapid hormonal rise in honey bees due to heat‐shock is mitigated by a primer pheromone

Insect Science, EarlyView.
We show that honey bee foragers increased juvenile hormone (JH) titers significantly after heat‐shocked for 1 h at 40 °C, but this increase is dependent on social conditions. Increase of JH titers only happened when bees were isolated (one worker bee per vial) but not in groups.

Polypropylene Nanoplastic Exposure to Respiratory Epithelial Barrier‐On‐Chip and Interfacial Interactions With Human Serum Albumin

Allergy, EarlyView.
Exposure to 305 nm PP NPs significantly disrupts the airway barrier‐on‐chip, reducing TEER, suppressing ZO‐1/ACE2 expression, and triggering ROS‐mediated apoptosis. In biological media, PP NPs exhibit a biphasic adsorption pattern, leading to the formation of a protein corona that increases their size to 364 nm.

Disordered Bile Acid Metabolism in Alcohol‐Related Hepatitis

Alimentary Pharmacology &Therapeutics, EarlyView.
Serum conjugated primary bile acids accumulate in alcohol‐related hepatitis due to downregulation of hepatocyte bile acid transporters. Hepatocyte growth factor is elevated in alcohol‐related hepatitis and downregulates BSEP expression. This detrimentally affects the hepatoprotective adaptive reduction in NTCP/increase in BSEP seen in cholestasis ...

Cost projections for Redox Energy storage systems [PDF]

A preliminary design and system cost analysis was performed for the redox energy storage system. A conceptual design and cost estimate was prepared for each of two energy applications: (1) electric utility 100-MWh requirement (10-MW for ten hours) for ...
