Abstract:
Palbociclib is used for breast cancer treatment along with letrozole. Five major impurities were observed during the synthesis as well as in forced degradation studies, out of which, three impurities were identified during the penultimate step of palbociclib API synthesis. These three impurities were confirmed as palbociclib desacetyl impurity (PDA impurity), palbociclib desacetyl hydroxy impurity (PDH impurity) and palbociclib desacetyl hydroxyl methyl impurity (PDHM impurity). These impurities were formed due to the usage of palladium catalyst during the pre-final reaction between 1 and 2. T

Abstract Carbon steel is susceptible to stress corrosion cracking (SCC) in fuel grade ethanol (FGE). The present study aimed at understanding if the SCC susceptibility of carbon steel was related to the impurities or minor constituents in FGE. SCC was noted in all six FGE samples tested in two laboratories. The characterization results gained thus suggest that the composition of the FGE varies depending on the biomass and/or production methods. However, it is not clear yet whether the SCC could be associated to one or several impurities or minor constituents. More efforts are needed to obtain

Abstract Pipeline transportation systems are the most cost-effective method to transport liquid or supercritical CO2 from points of capture to sites where it will be permanently stored or used for industrial purposes. Many factors complicate designing an efficient CO2 transmission pipeline and selecting materials. These factors include gas chemistry and impurities (O2, H2O, H2S), pressure, and velocity. The presence of impurities in supercritical CO2 can promote steel corrosion. The objective of this study was to investigate the corrosion behavior of three pipeline steels (X56, X65, and X100)

Abstract Deploying Carbon Capture, Utilization, and Storage (CCUS) is pivotal for achieving the International Energy Agency's Net Zero Emissions by 2050 goals. However, the global implementation rate puts this goal in peril due to high capital costs, exacerbated by the corrosive environment from water and industrial impurities in CO2 resources, necessitating costly corrosion-resistant alloys. Despite the prevalent belief in the excellent mechanical strength and chemical inertness of polymers to downhole corrosion environments, Fiber-reinforced Polymer Composite (FPC) materials have shown promi

Abstract:
Abstract The Integrated Surveillance Program, under the Department of Energy, is responsible for the periodic surveillance of storage containers containing plutonium-bearing materials. The container package consists of a stainless-steel three-layered structure with a convenience can that confines the material, and seal-welded inner and outer cans designed to isolate the materials for up to 50 years with minimal surveillance. The inner-can represents the first layer of containment. It was designed with the expectation that it would not be breached. Monitoring is carried by random and engineerin

Abstract:
The detection of non-metallic impurities and defects during the production of food is a critical task for every inspection system. Through recall campaigns caused by the contamination of food during the production process can corrupt the good reputation of companies for a long time. To minimize the risk a huge number of sensor technologies is implemented. The spectrum of sensors starts from the optical region over sensors in the infrared region to x-ray systems. The main disadvantage of most of the systems is the inability to detect non-metallic contaminations inside a product. The paper descr
