Aerators manufactured from fly ash composites

Chemicals / , ,

The Challenge / Concern:

Fly ash is the material of global concern produced at the numerous coal fired plants. Value added product with engineering rigor was desired that would consume significant quantities of fly ashes of varying composition. A technology was requested with such anticipation.

Brief (and non-confidential) Solution

Aerators are the porous and sturdy materials widely used to introduce gases in liquids. Principally, they are used in water treatment plants for operation of aeration, and also in chemical processes. We developed the rigid and porous material by using suitable scaffolds for fly ash. These materials after primary treatment were found to have desired strength and modulus. They can be casted to have specific shapes and cross sections. Testing of 3 samples was conducted in control environment for aeration in water, and found to have satisfactory control on air flow rate and diffusion.

Service / Project: Contract Research, Product Development

    An Online Service Offers Australians Tobacco – But Also “Stop Smoking” Messages

    A website has appeared offering customers in Australia the ability to buy tobacco products with delivery to their door. The website, which operates under the name Australia Tobacconist Hub, is full of mixed messages: aggressive marketing of budget tobacco products alongside disclaimers about the dangers of smoking.

    What the Service Offers

    The platform’s primary customer base is people who smoke seeking lower prices. Among the products listed are:

    Double Happiness brand — $190 per block (10 packets x 20’s)
    Manchester Sapphire Blue (Dubai Edition) — $220 per carton
    Manchester Special Edition Flow Red – Dubai Edition — $250 per carton
    Manchester Blue Crush – Dubai Edition — $250 per carton
    Dunhill Blue – UK Edition — $220 per carton
    Dunhill Red – UK Edition — $190 per carton
    Benson & Hedges Gold — $160 per block
    Zhongnanhai (???) — $180 per carton

    The seller stresses “affordable rates” (Cheap Tobacco Australia) and the availability of popular brands such as Marlboro, Manchester, Bossku, Double Happiness, and others.

    Logistics and Payment

    The seller promises quick, dependable, and private shipping across Australia (Fast Tobacco Delivery Australia). They state that they take bank transfers, USDT (cryptocurrency), PayPal, Wise, and other methods. Customer contact is done via WhatsApp, email, and other messaging apps — a typical practice in the shadow economy for internet cigarette shops.

    Mixed Messages

    Curiously enough, the same website that promotes tobacco sales (while officially noting that it is illegal to sell tobacco products to minors) also shows a “STOP SMOKING” banner with an image of a cigarette passing through human lungs.

    In a part named “STOP TOBACCO”, the text says:

    “Giving up smoking is hard, but every effort counts. Within minutes, your body starts recovering — and over time, your health and energy come back. Let’s start today!”

    This anti-smoking advice appears right next to a list of items for sale with prices from $160 to $250 per carton and a call to action: “Purchase cigarettes online in Australia for the lowest price.” Such hypocrisy is common of unlicensed or “grey market” tobacco shops that try to feign social responsibility while still pushing harmful goods.

    Legal Issues

    The text does not specify whether the seller holds a valid Australian retail license for tobacco. Australia is recognised for some of the most severe cigarette regulations globally, including plain packaging requirements and very large tobacco duties. The offer of “cheap” cigarettes — especially “Dubai Edition” or “UK Version” — often indicates products that have evaded taxes, been brought in illegally, or are fake.

    Summary

    The website in question is a clear illustration of a dark-market cigarette seller. It takes advantage of smokers’ wish for cheaper prices in the face of Australia’s high legal tobacco taxes, while using as a shield superficial “Stop Smoking” slogans and claims of customer care. Those thinking of purchasing should remember that buying unlicensed tobacco carries not only the chance of legal trouble but also a total absence of any assurance regarding product safety and authenticity.
