  • Publication number: 20260320527
    Abstract: The embodiments herein achieve a product development lifecycle process automation controller (140) that enables enterprises to go-to-market faster. The product development lifecycle process automation controller (140) do it through a proprietary platform, a humanAIze platform (for example), leveraging artificial intelligence (AI), GenAI, Agentic AI and Data Science. The platform is a collection of systems, tools and logics that enables faster deployment of Low-code/No-code SaaS platforms by automating more than 60% of manual labor intensive activities across the implementation cycle, making it ~30% or above faster.

  • Patent number: 8337795
    Abstract: A process to the production of silicon from amorphous silica is disclosed. The amorphous silica is formed from a material rich in silica, especially rice husk ash or silica fume. The process comprises subjecting the amorphous silica to leaching with a lixiviant of aqueous mineral acid, especially hydrochloric acid. Preferably, material rich in silica is roasted at a temperature of not more than 850° C., subjected to leaching and then subjected to a second roasting at a temperature of less than 750° C. The process provides for the production of high purity silicon, especially to the production of solar grade silicon (SoG-Si).
