Our scientific experts applied for the first time the 2018 EFSA Scientific Committee Guidance on Nanotechnology to the safety assessment of food additives. Titanium dioxide E 171 contains at most 50% of particles in the nano range (i.e. less than 100 nanometres) to which consumers may be exposed.
The precipitation of titanium dioxide involves the reaction of titanium sulfate with an alkaline solution to form titanium hydroxide, which is then calcined to produce titanium dioxide. The precipitation process is crucial for achieving the desired particle size distribution, crystallinity, and purity of the final product.
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.
In addition to reducing energy costs, threshold seal strips also play a crucial role in enhancing security.

Another significant advantage of dense foam strips is their weather resistance
. Many types of dense foam are heavily resistant to moisture, chemicals, and UV radiation, making them suitable for both indoor and outdoor applications. For instance, they can be utilized in weather stripping for doors and windows, creating an effective seal that prevents drafts and enhances energy efficiency. This not only contributes to lower energy bills but also helps maintain a comfortable temperature inside homes and buildings.
Installation Tips for 1% Foam Weather Stripping
Adhesive door seals, also known as weatherstripping or door sweeps, are designed to fill the gaps around doors. They create a tight seal when the door is closed, preventing air leaks that can lead to unwanted drafts. This is particularly crucial in climates with extreme temperatures, as the right seal can help maintain indoor temperatures, reducing reliance on heating and cooling systems. According to the U.S. Department of Energy, sealing just one poorly fitting door can save homeowners up to 10% on energy bills.

2. Temperature Tolerance EPDM materials can withstand a wide temperature range, typically from -40°C to 120°C (-40°F to 248°F), making them suitable for various thermal environments.
One of the primary reasons to use rubber edge trim for glass is safety. The edges of glass are often sharp and can pose a serious risk of injury. A cut from glass can result in severe wounds, requiring medical attention. Rubber edge trim provides a protective layer, effectively reducing the risk of cuts and injuries. By covering the sharp edges, it ensures that anyone handling or coming into contact with the glass is protected from potential accidents. This is especially important in high-traffic areas, homes with children, or facilities that cater to the elderly.
