   Mijn verwachting voor Pyrogenesis:
   Ik denk en hoop dat er binnen twee tot drie jaar op vele fronten bijzonder goede dingen gaan gebeuren.
   Als eerste denk ik een langdurig leveringscontract van TiAl poeder aan een grote afnemer in aviation. Ik denk binnen een jaar.
   In tunneling met plasma torches zie ik geen toekomt ( locale energievoorziening en warmte afvoer in de tunnel).
   Fumed silica is op termijn een goudmijn maar de investering voor een grote productie fabriek is voor de korte termijn een probleem.
   Er zal een grote mede investeerder gevonden moeten worden.
   Pfas vernietiging zal ook nog wel enkele jaren nodig hebben tot een volwassen rendement.
   
   Ik wacht met verdere aankopen tot een doorbraak die echt fikse lange termijn opbrengsten genereert.
   
   Risico blijft dat Pyr op korte termijn in geldnood komt, en misschien bijzondere maatregelen moet treffen.

   Pyrogenesis heeft de 10 procent provisie over de omzet van Hpq Silicon verruild voor een 50 procent ownership in Hpq Silicon.
   Mogelijke redenen:
   Een betere kans op financieel leenkapitaal voor Hpq.
   Meer zekerheid tegen een vijandelijke overname van Hpq.
   Het idee dat een 50 procent eigenaarschap meer waarde brengt voor Pyrogenesis dan de provisie van 10 procent over de omzet.
   Op termijn wordt de boekwaarde van Pyrogenesis groter.
   
   Al met al een positief signaal. De verwachting is dat fumed silica een succesverhaal wordt.

    Pyro heeft een proces om pfas te vernietigen. Pfas zit in water, ook in drinkwater. Ik heb me een tijd lang afgevraagd hoe pfas uit water kan worden verwijderd. Vandaag las ik over hoge concentraties in zeeschuim. In het artikel stond deze paragraaf: 'Dat PFAS aan schuim bindt, is niet alleen maar slecht nieuws. Het principe wordt namelijk juist ook ingezet voor waterzuivering. „Een van de manieren om vervuild water te zuiveren is lucht in het water te blazen zodat zich schuim vormt”, zegt Smith. „De PFAS gaan hierin zitten, en dan kan het eenvoudig worden verwijderd. Het is een simpele methode. Door het meermaals te beluchten is de concentratie PFAS in het uiteindelijke schuim tot wel 100.000 keer hoger dan in het water. ” Een kans voor pyro?

    Het probleem om de Pfas soorten te onttrekken uit vloeibare stoffen is zo goed als opgelost. Nederlandse vinding met circulaire moleculen die het Pfas vangen.
    De verzamelde Pfas zal dan vernietigd moeten worden (lees: ontleed moeten worden tot stoffen die wel een binding aan kunnen gaan met andere stoffen).
    
    Dit ontleden kan Pyrogenesis met de plasma torches door pyrolyse ( extreme hitte zonder zuurstof toelating).
    Een mogelijke oplossing, wel duur.

    Revolutionizing Steel: Breakthrough in 3D Printing of 17-4 PH Stainless Steel
    
    Synopsis: Researchers have developed a method for producing 17-4 PH stainless steel through 3D printing, overcoming significant challenges in the process.
    Thursday, October 17, 2024
    
    Recent advancements in additive manufacturing, commonly known as 3D printing, have enabled researchers to consistently produce 17-4 PH stainless steel, a material renowned for its strength and corrosion resistance. Traditionally, printing with steel and other alloys has posed considerable challenges due to the rapid temperature fluctuations that occur during the laser heating process in 3D printers. These thermal changes can disrupt the atomic arrangement of the metal, making it difficult to achieve the desired toughness.
    
    To tackle this issue, scientists utilized bright X-ray beams to monitor the quick changes in temperature and material structure in real time. By observing these transformations, researchers could adjust the chemical composition of the steel during the printing process, resulting in a more durable final product. This innovative approach not only enhances the properties of 17-4 PH stainless steel but also opens new avenues for its production.

    Revolutionizing Steel Production: High-Performance Plain Carbon Steels via 3D Printing
    
    Synopsis: Recent advancements in 3D printing technologies have enabled the production of high-performance plain carbon steels. These steels, produced using metal 3D-printing methods, offer superior tensile and impact properties, comparable to ultra-high strength alloy steels, while simplifying material compositions and enhancing customization.
    Friday, November 22, 2024
    
    Over the past century, the mechanical performance of structural metals, particularly steel, has significantly improved. However, this progress has often been accompanied by increasing alloy complexity. Engineers and manufacturers developed a vast array of specialized compositions to meet specific mechanical and performance demands. While this innovation led to stronger and more durable materials, it also brought challenges such as higher production costs, complicated recycling processes, and vulnerabilities in supply chains due to the distribution of raw materials. In recent years, researchers have begun to rethink this approach, exploring ways to simplify alloy compositions without compromising performance. A groundbreaking study in Nature Communications has highlighted how metal 3D-printing could provide a solution to this dilemma by enabling the creation of high-performance plain carbon steels.
    
    Traditional steel manufacturing techniques typically require the use of complex alloying elements to achieve specific mechanical properties such as ultra-high strength, wear resistance, or corrosion resistance. These alloying elements, while effective, complicate the production process and make recycling difficult. For example, the production of high-performance martensitic steels often requires precise control over the chemical composition and cooling rates, which can involve slow, energy-intensive processes like heat treatment and quenching. Such methods not only increase the costs of production but also limit the design flexibility of components due to challenges in controlling material properties across different shapes and sizes.
