Effective Method to Collect Indoor Floating Aerosols Using Cooling Equipment

open access: yesAtmosphere, 2023
If we collect aerosols containing SARS-CoV-2 with condensed water and obtain the solution, a sensing device can detect the viruses, and we can easily take prompt countermeasures.

Condensate Phase Microscopy [PDF]

open access: yesPhysical Review Letters, 2014
We show that the phase of a Bose-Einstein condensate wave-function of ultra-cold atoms in an optical lattice potential in two-dimensions can be detected. The time-of-flight images, obtained in a free expansion of initially trapped atoms, are related to the initial distribution of atomic momenta but the information on the phase is lost.

Hagedorn transition and chronology protection in string theory [PDF]

open access: yes, 2005
We conjecture chronology is protected in string theory due to the condensation of light winding strings near closed null curves. This condensation triggers a Hagedorn phase transition, whose end-point target space geometry should be chronological ...

Numerical Simulation of Volatile Organic Compounds during Condensation in a Vertical Tube

open access: yesProceedings, 2020
The purpose of this study is to analyze the combined heat and mass transfer through condensation of volatile organic compounds (VOCs), particularly alcohol (n-butanol-propanol) in the presence of non-condensable gas inside a vertical tube.

A Heat Exchanger with Water Vapor Condensation on the External Surface of a Vertical Pipe

open access: yesEnergies, 2022
The paper is concerned with water vapor condensation on vertical pipes. The vertical position of pipes in a condenser is not discussed very often. Its application has a number of particularities in terms of the numerical determination of heat transfer ...

Comment on "Charged vector mesons in a strong magnetic field" [PDF]

open access: yes, 2013
In a recent paper Y. Hidaka and A. Yamamoto [Phys. Rev. D 87 (2013) 094502] claim -- using both analytical and numerical approaches -- that the charged rho mesons cannot condense in the vacuum subjected to a strong magnetic field.

Improved General Correlation for Condensation in Channels

open access: yesInventions, 2022
The present author’s general correlation for condensation in mini and macro channels which has been verified with an extreme range of data was further evaluated at quality x close to 1. Large deviations were found at quality x ≥ 0.99. The correlation was

Condensate Halos in Condensation Frosting

open access: yesAdvanced Science
Abstract The freezing of water drops on cold solid surfaces is ubiquitous in nature, and generally causes serious technological, engineering, and economic issues in industrial applications. Despite longstanding research efforts, existing knowledge on dropwise freezing is still limited, as this phase‐change phenomenon is always ...
