A non-invasive capacitive sensor to investigate the Leidenfrost phenomenon: a proof of concept study.

A volatile sessile liquid droplet or a sublimating solid manifests levitation on its own vapor when placed on a sufficiently heated surface, illustrating the Leidenfrost phenomenon. In this study, we introduce a non-invasive capacitance method for investigating this phenomenon, offering a potentially simpler alternative to existing optical techniques. The designed sensor features in-plane miniaturized electrodes forming a double-comb structure, also known as an interdigitated capacitor.

Anti-Quorum Sensing and Anti-Biofilm Activity of Ginger () Rhizomes against Multidrug-Resistant Clinical Isolates of .

Background: The aim of this study was to determination of Anti-Quorum Sensing (AQS) and anti-biofilm potential of the methanol extract of ginger () rhizomes against multidrug-resistant clinical isolates of ().

Methods: The AQS activity of ginger was determined against () ATCC 12472 (CV12472), a biosensor strain, in qualitative manner using the agar well diffusion method. The violacein pigment inhibition was assessed to confirm AQS activity of ginger.

Inhibition of Quorum Sensing Regulated Virulence Factors and Biofilm Formation by against Multidrug-Resistant .

Objectives: The quorum-sensing-inhibitory and anti-biofilm activities of the methanol extract of leaves were determined against clinically isolated multidrug-resistant .

Methods: The preliminary anti-quorum-sensing (AQS) activity of eucalyptus was investigated against a biosensor strain ATCC 12472 (CV12472) by using the agar well diffusion method. The effect of sub-minimum inhibitory concentrations (sub-MICs) of the methanol extract of eucalyptus on different quorum-sensing-regulated virulence factors, such as swarming motility, pyocyanin pigment, exopolysaccharide (EPS), and biofilm formation, against clinical isolates (CIs 2, 3, and 4) and reference PA01 of were determined using the swarm diameter (mm)-measurement method, chloroform extraction method, phenol (5%)-sulphuric acid (concentrated) method, and the microtiter plate assay respectively, and the inhibition (%) in formation were calculated.

Investigation on Temperature Dependent Inductance (TDI) of a planar Multi-Layer Inductor (MLI) down to 4.2 K.

This paper presents an investigation of the temperature dependence characteristics specific to cryogenic planar Multi-Layer Inductors (MLIs). This paper establishes that the inductance of a planar MLI at a specific frequency varies with temperature when the sensor is cooled down to 4.2 K while providing a detailed analysis of various possible factors that might contribute to the variation in the sensor performance, such as the thermal deformation and the variation in the properties of sensor materials, using a combination of experiments and simulations.

Antibacterial efficacy of different combinations of clove, eucalyptus, ginger, and selected antibiotics against clinical isolates of .

Background: Nosocomial infections caused by multidrug-resistant are commonly treated with conventional antibiotic which may lead to some serious side effects in the patients. Conventionally, medicinal plants, including clove, eucalyptus, and ginger, are used for the safe and effective treatment of several diseases.

Aims And Objectives: The aim and objective of this study is to evaluate the combined antibacterial efficacy of medicinal plants (clove, eucalyptus, and ginger) and selected antibiotic and also combined efficacy of different plants extracts against clinical isolates of .
