Genotoxicity refers to the ability of a chemical substance to damage DNA , the genetic material of cells. As genotoxicity may lead to carcinogenic effects, it is essential to assess the potential genotoxic effect of a substance to conclude on its safety.
“Unlike some other chemicals used in food, titanium dioxide has no nutritive, preservative, or food safety function—its use is purely cosmetic,” said CSPI principal scientist for additives and supplements, Thomas Galligan. “The prospect of titanium dioxide nanoparticles damaging DNA is concerning enough for us to recommend consumers avoid foods that have it.”
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 the ever-evolving world of fashion and textiles, the double needle technique has emerged as a cornerstone for both durability and aesthetic appeal
. This method, often utilized in the production of garments, particularly in stitching and finishing, has garnered attention not only for its functional benefits but also for its cost implications. The double needle price, therefore, has become a noteworthy topic in discussions surrounding garment manufacturing, affecting everything from production costs to retail pricing.Lock stitch is a sewing technique that involves interlocking two threads—one from the needle and the other from the bobbin—to create a strong seam. This method is particularly advantageous for securing the seams of jumbo bags because it provides a tight, secure closure that can withstand significant tension and pressure. Unlike other stitching methods, lock stitch produces a consistent and uniform seam, reducing the likelihood of bag failure due to seam separation.
2. Professional Finish The aesthetic appeal of garments produced with a double needle machine is undeniable. The parallel rows of stitching create a polished and refined look, making garments more appealing to consumers.
The backstitch is a fundamental sewing technique that serves to secure the start and end of a seam. Traditionally, this process required the sewist to manually reverse the stitching at both ends of a seam, which could be tedious and time-consuming. With the advent of sewing machines equipped with an automatic backstitch feature, this tedious step has been streamlined. The machine automatically stitches backward for a few stitches, locking the seam in place without any manual intervention.
A heavy duty basic sewing machine is specially designed to handle a wide range of fabrics, including thick and heavy materials such as denim, canvas, and upholstery fabric. Unlike standard sewing machines, which may struggle with these tougher materials, heavy duty machines come equipped with stronger motors, reinforced structures, and specialized stitching capabilities that make them ideal for demanding sewing projects.
