China’s ambition to conquer the depths of the ocean is entering a new phase. After years of investing in scientific exploration and deep-sea technologies, the country is now preparing to bring tourists into the underwater world. Chinese state media China Daily revealed plans for a new manned submersible capable of carrying passengers to depths of #1000metres . The project is being led by the China Ship Scientific Research Center ( #CSSRC ), a subsidiary of China State Shipbuilding Corp ( #CSSC ). According to Ye Cong, director of the CSSRC in Wuxi, Jiangsu province, engineers of the rearch team plan to build a prototype before the end of this year. “After more than four years of research, engineers have finalised the structural design,” he said, adding that if everything goes according to plan, the #deepseatourism #submersible will be ready for launch and commercial operation before 2030. One of the most striking features of the future submersible is expected to be its panoramic #und...

Deutsche Aircraft and Hexcel today jointly announced the signing of a long‑term industrial partnership and supply agreement focused on advanced composite solutions for the D328eco, the next‑generation regional turboprop designed, certified, and industrialised in Europe. The agreement was formalized at the ILA Berlin Air Show, at the BDLI Pavilion, emphasizing the role of ILA as Germany’s leading aerospace exhibition and a key platform for advancing Europe’s aerospace industrial ecosystem. The partnership reflects a shared commitment to long term cooperation, industrial resilience, and technological excellence anchored in Europe. Under the agreement, Hexcel and Deutsche Aircraft will collaborate closely to integrate advanced composite solutions into the D328eco airframe. The materials are engineered to meet the programme’s stringent mechanical, weight, and environmental requirements, supporting both performance and sustainability objectives. The composite solutions will be applied in pr...

Evonik develops solutions to enhance the chemical recycling of plastics, offering specialized catalysts and adsorbents to improve the quality of pyrolysis oil. In the pyrolysis process, plastic waste is broken down into its chemical building blocks at high temperatures and in the absence of oxygen. The primary product of this process, pyrolysis oil, can supplement fossil feedstocks like naphtha derived from crude oil. Pyrolysis oil is further processed in steam crackers, which produce the essential building blocks for new plastics, such as ethylene and propylene.  However, pyrolysis oil often contains impurities such as chlorine, nitrogen, or silicon, which can compromise the efficiency and operational safety of steam crackers. “Cracker operators apply strict quality standards to the feedstocks they use,” says Hendrik Rasch, who is responsible for Circular Packaging and Plastics Recycling in Evonik’s Next Markets Program. “This is precisely where our products come in. They help to ...

That is why ORNL’s three-lobed filament is clever. The shape works twice: ▫️Mechanically thick: Higher area moment of inertia → more resistance to local fiber bending. ▫️Chemically thin: Shorter oxygen diffusion path during PAN oxidation → faster, more uniform core stabilization. That matters because oxidation is slow. If oxygen reaches the center faster, line speed can go up without leaving an under-stabilized core. Less hidden core and more perimeter. Compression and throughput attacked from the same cross-section. 📚Source(s): DOE-funded researchers developing high-throughput, low-cost carbon fiber — CompositesWorld Initial Assessment of Alternative Carbon Fiber Geometries — ORNL / S...

FDM (Fused Deposition Modeling) This is the most widely used technique, where thermoplastic filaments are melted and layered to create the final structure. It is cost-effective, user-friendly, and ideal for rapid prototyping, though it generally offers lower resolution compared to other methods. 2. SLA (Stereolithography) SLA printers use a laser to cure liquid resin with exceptional precision. They produce highly detailed, smooth-surface parts, making them perfect for applications in dentistry, jewelry, and micro-engineering. 3. DLP (Digital Light Processing) Similar to SLA but faster, DLP cures an entire layer at once using pro...

  The inauguration of the CPVC Resin plant in Vilayat, Gujarat stands as a testament to what strong local partnerships can achieve. The occasion was graced by the Hon’ble Chief Minister of Gujarat Shri Bhupendra Patel alongside Rebecca Liebert, (CEO, Lubrizol) and Jayant V Dhobley (Business Head & CEO Global Chemicals, Aditya Birla Group), underscoring the importance of this milestone for the industry and the region. Built in collaboration with GRASIM INDUSTRIES LIMITED ( ADITYA BIRLA GROUP), the facility combines global technology with deep local insights—enabling a more agile, resilient CPVC supply ecosystem for India. As Abhishek Shrivastava (VP & MD Lubrizol IMEA) shared: “This facility is more than infrastructure. It is the result of trust, partnership, dedication, and people believing in a shared vision.” A few glimpses from a day that sets the foundation for a stronger #CPVC future in India. source : Lubrizol IMEA
