This article discusses the discovery of phosphorescent lithopone on watercolor drawings by American artist John La Farge dated between 1890 and 1905 and the history of lithopone in the pigment industry in the late 19th and early 20th centuries. Despite having many desirable qualities for use in white watercolor or oil paints, the development of lithopone as an artists’ pigment was hampered by its tendency to darken in sunlight. Its availability to, and adoption by, artists remain unclear, as colormen's trade catalogs were generally not explicit in describing white pigments as containing lithopone. Further, lithopone may be mistaken for lead white during visual examination and its short-lived phosphorescence can be easily missed by the uninformed observer. Phosphorescent lithopone has been documented on only one other work-to-date: a watercolor by Van Gogh. In addition to the history of lithopone's manufacture, the article details the mechanism for its phosphorescence and its identification aided by Raman spectroscopy and spectrofluorimetry.

2. Infrared (IR) Spectroscopy IR spectroscopy is a non-destructive method that measures the absorption of infrared light by gas molecules. It is effective for measuring gases like carbon dioxide, methane, and volatile organic compounds. The technique offers high sensitivity and can be used for continuous monitoring.
Moreover, the development of biogas and synthetic natural gas from renewable sources holds promise for the future. These alternatives not only enhance energy diversity but also reduce dependence on conventional fossil fuels. Some countries are already incorporating biogas into their energy mix, highlighting a path toward a sustainable future where natural gas can play an integral role in an environmentally responsible manner.
A gas pressure reducer, also known as a pressure regulator, is a mechanical device designed to reduce the high pressure of gas into a lower, more manageable pressure. It ensures that the output pressure remains constant and within a predetermined range, regardless of fluctuations in the input pressure. This capability is vital in many scenarios, as excessive pressure can result in dangerous situations, operational inefficiencies, and equipment damage.
Heat exchangers are essential devices in various industrial processes and applications where there is a need to transfer heat from one fluid to another. They play a critical role in improving energy efficiency and optimizing thermal management in systems ranging from power generation and chemical processing to HVAC (heating, ventilation, and air conditioning) and refrigeration.
A gas heat exchanger is a device that facilitates the transfer of thermal energy between two or more gas streams without the two streams mixing. The principle of operation is based on conduction, convection, and the laws of thermodynamics. By separating the gases with a solid barrier, heat can move from the hotter gas to the cooler one, thus increasing overall energy efficiency.
