So sorry for disappearing without a word for so long!
I didn't want Sonic Prime spoilers, but didn't have the money for netflix to watch the show. I was planning on doing a quick marathon of it and my fam's house but every time I'd try my mom would be like "You want to watch sonic show instead of spend time with us? :(" soooo it took a while
My birthday was last week and when my mom asked if I had a present wishlist I told her I wanted to finish the show, so I'm finally done (I also got sonic legos. Boy I'm obsessed)
I've also been super busy gearing up to graduate in May. For my english major I'm writing an entire novel, and for my very mineralogy-focused geology minor I'm writing a report on all of the minerals discovered in the past year. Both are super fun but have me super busy.
I wanna give a thank you to @cinnatwolover, you don't know how much it means to me. Knowing that people enjoy the stuff I create so much is really helping with my confidence and motivation for my novel.

Chemical synthesis using titanium dioxide: An eco-friendly and innovative approach
Heterocyclic compounds are organic molecules with a ring structure comprising at least two or more elements. In most cases, these rings are composed of carbon atoms along with one or more other elements such as nitrogen, oxygen, or sulfur. They are highly sought after as raw materials in the chemical and pharmaceutical industry, owing to their versatility and excellent physiological activities.
While several methods are available for synthesizing these compounds, most of them involve high temperature and pressure conditions, or the use of precious metal catalysts, adding to the economic and environmental cost of producing heterocyclic organic compounds.
Now, however, a team of researchers from Japan and Bangladesh have proposed a simple yet effective method for overcoming these challenges. Their study was recently published in the journal Advanced Synthesis & Catalysis. Using the proposed strategy, the team demonstrated the synthesis of 20 sulfur-containing heterocyclic compounds in the presence of photocatalyst titanium dioxide (TiO2) and visible light.
Teacher masking a child during COVID pandemic. A recent study confirmed disposable face masks released dangerous levels of the carcinogen titanium dioxide (TiO2). The masks were required by Dr. Fauci and his cronies during the COVID pandemic. The study found that the TiO2 levels exceeded the acceptable exposure level by four times or more. Here…
Hmmm well if I remember correctly many gems are oxidized metals right, anatase being titanium dioxide?, well, wasn't there a way to seperate the dioxide from the titanium?, I want to know if it's possible to make an anatase holding necklace made purely out of anatase sourced titanium
Batatas: Astute observation, lab rat- you really have been paying attention!
Batatas: It's true, many gemstones have metals in their chemical make ups- in fact, metals are often what cause the unique colors of precious gems!
Batatas: Titanium oxide especially in its anatase structure is a mineral- think of it as the raw state of a gemstone. It's a naturally occurring solid with a crystalline structure and a clear chemical composition.
Batatas: For your question specifically… It is possible to break the bonds of the two oxygen atoms from the titanium atom to purify metallic titanium. It's not easy, in fact, TiCl4 is much more commonly used to produce metallic titanium, but it is possible in recent years through combined methods of Kroll, electrolysis, and calciothermic reduction. These all have their own issues, TiO2 is chemically inert in its 4+ oxidation state but it's possible.
Batatas: It's important to remember that while Anatase is made of titanium oxide, assuming that compounds with the same chemical formulas will act the same isn't quite true- Remember about isomers? Anatase is a polymorph crystal equivalents of isomers, same chemical formulas but differing 3D structures that cause different properties! That's why Rutile and Anatase are different, even if they're made of the same thing.
Batatas: While producing elemental titanium is possible from anatase, it's really difficult. Not to mention expensive and prone to very low yield. But remember- especially in jewelry, the titanium you see isn't pure elemental titanium- it's titanium alloys, mixtures of metals! In the field, pure elemental titanium is almost never worked with because it's just so difficult to use, it's usually mixed with other metals like copper or vanadium- so be aware it won't be pure titanium in your necklace-
Jacq: Hm... Batatas used to work in refineries before he became a teacher- I think he's saying that it's not easy. Heh.
Mars – the company that owns Skittles – invites its customers to “taste the rainbow” when they tear open a package and pour some of the multi-colored candies into their mouths. However, what they’re really tasting is titanium dioxide (TiO2).
Now, a class-action lawsuit filed in the U.S District Court for the Northern District of California Thursday argues that the coloring chemical is a “known toxin” that renders Skittles “unfit for human consumption,” as USA TODAY reported.
“Based on Defendant’s omissions, a reasonable consumer would expect that the Product can be safely purchased and consumed as marketed and sold,” the lawsuit read, as USA TODAY reported. “However, the Products are not safe and pose a significant health risk to unsuspecting consumers.”
TiO2 was approved by the Food and Drug Administration (FDA) for use in food in 1966, according to the Los Angeles Times. The U.S. agency still maintains that it’s safe to use as food coloring as long as no more than one percent of the weight of the food in question is added.
However, the story is different across the Atlantic. In May of 2021, the European Food Safety Authority said there was enough research to suggest the chemical was not safe to eat. This is because it has been linked to genotoxicity – the ability to damage a person’s DNA and therefore cause cancer. In response, the European Commision has moved to ban the chemical in food by August of this year, according to The Washington Post.
White masterbatch is a highly sought-after type of plastic additive that is used to impart a bright and consistent white color to various plastic products. It is typically used in the production of plastic goods that require a white base, such as packaging materials, consumer goods, and automotive parts.
So, what exactly is a white masterbatch? Simply put, it is a concentrated mixture of titanium dioxide (TiO2) and a carrier resin, such as polyethylene (PE) or polypropylene (PP). The TiO2 pigment is added to the carrier resin in high concentrations, resulting in a masterbatch that can be added to plastic products during the manufacturing process to achieve a uniform and opaque white color.
There are several benefits to using white masterbatch in plastic production. For one, it offers a cost-effective alternative to producing white plastic products, as it eliminates the need for manufacturers to purchase expensive pre-colored resins. Additionally, it allows for greater flexibility and control in the manufacturing process, as it can be added to plastic products in varying concentrations to achieve the desired shade of white.
White masterbatch is also highly customizable, as it can be formulated with other additives to achieve specific properties, such as UV resistance, flame retardancy, and antistatic properties. This makes it an ideal additive for a wide range of plastic applications, from food packaging to automotive parts.
However, it is important to note that not all white masterbatch products are created equal. The quality of the masterbatch can vary greatly depending on the manufacturing process and the quality of the raw materials used. For this reason, it is important to work with a reputable supplier who can provide high-quality white masterbatch products that are tailored to the specific needs of your application.
In conclusion, white masterbatch is a valuable additive in the plastic industry that offers a cost-effective and customizable solution for achieving a bright and consistent white color in plastic products. By working with a trusted supplier, manufacturers can ensure that they are using high-quality white masterbatch products that meet their specific requirements and standards.

Team develops new gold nanocluster-rich titanium dioxide photocatalyst for the oxidative coupling of methane
The hydrocarbon methane is highly abundant on Earth, yet its release is now known to contribute to surges in temperature and climate change. In recent years, researchers have been trying to devise reliable methods to directly convert methane into other fuels and chemicals with valuable real-world applications.
These strategies include catalyst-based methods to prompt the oxidative coupling of methane to substances containing the green gas diatomic carbon (C2). This reaction, however, typically requires extreme and challenging environmental conditions, due to the unfavorable characteristics of the thermocatalysts introduced so far.
Researchers at University College London, University of Liverpool have recently developed a new photocatalyst that could advance the oxidative coupling of methane. This photocatalyst, introduced in Nature Energy, is based on titanium dioxide (TiO2 ) loaded with gold (Au) nanoclusters.
"Photocatalytic oxidative coupling of methane (OCM) produces C2 molecules that can be used as building blocks for synthesis of fuels and chemicals," Xiyi Li, Chao Li and their colleagues wrote in the paper. "However, the yield rate and the selectivity of C2 products are still moderate due to the stable nature of methane molecules."
