The Experimental Study of PVTx Properties of Near Aeotropic Mixture Refrigerant R290/R134a

Zhileng xuebao, 2014
In order to get the thermophysical properties of mixed refrigerants R134a/R290, the author built PVTx experimental system with high accuracy. Based on the Burnett method, the author measured the PVT properties of R134a/R290 with mass fraction 50%/50%, 55%

Pre‐analytical optimization of cell‐free DNA and extracellular vesicle‐derived DNA for mutation detection in liquid biopsies

Molecular Oncology, EarlyView.
Pre‐analytical handling critically determines liquid biopsy performance. This study defines practical best‐practice conditions for cell‐free DNA (cfDNA) and extracellular vesicle–derived DNA (evDNA), showing how processing time, storage conditions, tube type, and plasma input volume affect DNA integrity and mutation detection.

A novel quinazolinone insulin receptor inhibitor and its synergy with an EGFR inhibitor in glucose‐driven glioblastoma

Molecular Oncology, EarlyView.
The novel styrylquinazolinone‐based molecule W1B effectively suppresses glioblastoma by inhibiting IGF1R and EGFR. In high‐glucose microenvironments driving tumor resistance, W1B acts synergistically with the EGFR inhibitor dacomitinib. This combination safely blocks compensatory survival signaling in zebrafish xenograft models. Showcasing promising in

Evaluation of Compressor Reliability for HFO Refrigerants

, 2021
Responses to an international flamework on climate change, such as the Kigali Agreement in 2016, have been discussed in an industrial field. The phase down regulation of CFC and HCFC refrigerant has been discussed and performed under the Montreal ...

Screening and epitope characterization of Nidogen‐2‐specific nanobodies

FEBS Open Bio, EarlyView.
Camel immunization and phage display were employed to generate high‐affinity VHH nanobodies against Nidogen‐2. After library construction, biopanning, ELISA screening, sequencing, and recombinant expression, selected nanobodies were purified and characterized, leading to the preliminary exploration of a nanobody‐based sandwich ELISA for specific ...

Prediction of solid formation conditions in mixed refrigerants with iso-pentane and methane at high pressures and cryogenic temperatures

, 2022
High boiling-point components in mixed refrigerants can improve the performance of natural gas and hydrogen liquefaction facilities. However, such heavy compounds can freeze out from the refrigerant mixture, posing blockage and plant shutdown risks for ...

Improving the energy effectiveness of domestic refrigerators by the application of mixed refrigerants [PDF]

, 1978
A critical review of U.S. and foreign literature on the use of a mixture of refrigerants rather than a single one in a refrigeration unit indicates that energy can be conserved in properly arranged systems. An independent analytical study performed under the current contract using a 50% mixture of R-12 and R-114 in a two-evaporator refrigerator typical

Calculation of the operating mode of the mixing refrigerator

IOP Conference Series: Earth and Environmental Science, 2018
This article considers the calculation of a mixing refrigerator (contact refrigerator) taking into account the absorption of gaseous components. Calculation of operating mode and definition of optimal operating conditions of the machine that provides the given final gas temperature is carried out.

Performance analysis of vapor compression refrigeration system using mixed refrigerant R410A

International Journal of Energy Applications and Technologies, 2021
Mixed refrigerants are obtained from mixing pure refrigerants in specific proportions and it is known as mixed refrigerants. Mixture refrigerants are divided into two groups according to their thermodynamic behavior: zeotropic mixtures and azeotropic mixtures.
