https://www.selleckchem.com/products/elexacaftor.html The high photocatalytic activity of ZnO/CXG composite is attributed to (i) the formation of small (8-10 nm) and well-crystallized ZnO nanoparticles anchored to the carbon substrate and (ii) to the modification of the xerogel surface chemistry. Indeed, O2 plasma treatment of the CXG promotes the generation of hydroxyl, carbonyl and carboxyl surface functional groups, which are polar and acidic, while the NH3 plasma treatment mainly leads to the formation of polar and basic amino groups. While both plasma treatments promote the formation of polar functional groups, which enhance the CXG wettability, the formation of acidic groups is identified as beneficial for the adsorption of the RhB dye, while basic groups are detrimental. OBJECTIVES When considering PreExposure Prophylaxis (PrEP) as a HIV prevention method, many rely on information available online. Limited research has examined the quality, including readability, of PrEP information on the Internet. The current study evaluates the readability of PrEP information online employing six commonly used readability tests. STUDY DESIGN This is a cross-sectional study. METHODS Using the Google Chrome browser, a search for articles was conducted using two terms "pre-exposure prophylaxis" and "Truvada." The URLs of the first 50 English language websites for each term were recorded to create the overall study sample of 100 unique websites. Using six established readability scales, we determined the readability scores for each examined website. Websites were stratified by .com, .org, and .gov URL extensions to compare readability metrics. RESULTS Mean Flesch-Kincaid Grade Level (FKGL) was 9.5 (SD = 2.2), mean Gunning Fog Index (GFI) was 11.1 (SD = 2.7), mean Coleman-Liau Index (CLI) was 11.3 (SD = 2.0), while mean Simple Measure of Gobbledygook (SMOG) Grade Level was 12.1 (SD = 1.8). Using Flesch-Kincaid Reading Ease (FRE), one article was found easy to read, while 23 wer
