Green lubrication and microstructure design to enhance wear resistance
Increasing the lifespan of different tribosensitive components while reducing environmental impacts is becoming a more important area of research. A possible approach to solving this issue is the use of solid lubricants to enhance the wear resistance of different components. Another approach is the use of “green or environmental” fluids for enhancing lubrication where removing or decreasing the use of ecotoxic oils for lubrication is the goal. Another answer is by using components that are wear-resistant through enhanced microstructure design.
Challenges facing the use of solid lubricants include:
• Low mechanical strength
• Limited temperature applicability
• High application costs.
Andy Nieto, assistant professor at the Naval Postgraduate School in Monterey, Calif., says reducing friction and effectively dissipating frictional heating are key mechanisms in reducing wear. Two-dimensional (2D) nanomaterials are one possible approach for solid lubricants that create protective surface layers as solid-state lubricants.
New 4IR strategy envisions Gauteng as ‘Silicon Valley of Africa’
The Gauteng Provincial Government (GPG) has unveiled its 4IR Growth and Digitalisation Strategy, which seeks to provide fully-digital public services to citizens and position the province as the “Silicon Valley of Africa”. The new strategy, announced during a virtual media conference on Friday, is spearheaded by the GautengDepartment of e-Government and the 4IR advisory panel – a 15-member panel appointed by Gauteng premier David Makhura, to support government in ensuring citizens access. Driving innovation through IoT. Sqwidnet can give you the tools to bring your ideas to life. Connect with us. Providing an outline of the 4IR strategy, advocate Pieter Holl, stream lead of the Gauteng Provincial 4IR Panel and CEO of The Innovation Hub, explained the strategy seeks to further drive the implementation of the Grow Gauteng Together (GGT) 2030 roadmap, and facilitate the adoption of new technologies to ensure all Gauteng’s citizens benefit from a fully modernised public service.
Carlsberg and Corona tackle water and plastic waste: The sustainability success stories of the week
After parent company AB InBev announced that three major businesses – namely Unilever, Colgate-Palmolive and Coca-Cola – are now supporting its 100+ Accelerator to fund sustainable start-ups, beer brand Corona has posted its own update on start-up financing.
The brand is making funds of up to $100,000 per business available to startups working to develop solutions to the world’s plastic pollution problem. To apply for funding under the scheme, called the Corona Plastic Free Challenge, applicants will need to outline how their product, system or technology can be used to reduce or remove plastic from a specific part of the beverage supply chain. Specific focus areas are plastic bottle cap liner alternatives and solutions for keeping products on pallets during transportation without plastic film.
