Study of Performance Changes in Centrifugal Compressors Working in Different Refrigerants
EnergiesCentrifugal compressors are commonly used in heating, ventilation, and air conditioning (HVAC) systems. The current generation of refrigerants in HVAC systems have very low ozone depletion potential, but most of them are still considered as containing ...

Multifactorial Screening for Fine‐Scale Selection of CCS Industrial Clusters and Hubs in Brazil
Greenhouse Gases: Science and Technology, EarlyView.ABSTRACT As Brazil moves toward implementing its decarbonization commitments, carbon capture and storage (CCS) hubs are emerging as a key pathway for large‐scale CO2 abatement in hard‐to‐abate sectors. This paper presents a multifactorial, data‐driven framework to screen and prioritize potential CCS industrial clusters and hubs across Brazilian regions,

G2‐PASE: A Novel, Rapid, and Reliable Measure of Plaque Psoriasis Severity
JEADV Clinical Practice, EarlyView.ABSTRACT Background The Psoriasis Area and Severity Index (PASI), a composite measure of plaque psoriasis disease severity, is commonly used to determine treatment eligibility and response, but is time consuming for every‐day clinical use. The Gulliver‐Gestalt‐Psoriasis Area Severity Estimate (G2‐PASE) was developed to approximate PASI scores using ...

Low GWP Refrigerants for Air Conditioning Applications
, 2014 Refrigerants with low environmental impact have been developed as replacements for R22 and R410A in air conditioning applications. L-20 and L-41 have been evaluated in representative residential equipment. This study discusses the performance at high ambient temperatures (warm climate) and potential design changes.

International Journal of Chemical Kinetics, EarlyView.ABSTRACT The atmospheric chemistry of 1,4‐difluorobutane (CFH2CH2CH2CFH2) was investigated through a kinetic and mechanistic study of the reaction with chlorine (Cl) atoms and hydroxyl (OH) radicals. Using Fourier transform infrared (FTIR) spectroscopy and relative rate methods, the rate constants (k) for the reactions were determined at 298 ± 2 K as k(
