HOT article: Making metal surfaces strong, resistant, and multifunctional by nanoscale-sculpturing

Surface properties are critically important for metal applications, especially when using alloys or composite. A key factor in these properties is the layers of metal oxide that develop on metal surfaces – how these layers form and dissolve has a huge impact on the surface stability. Conventional methods for creating metal surfaces often result in uneven oxide layers, weakening the properties.

Nanosculpturing, on the other hand, allows oxide deposition and dissolution to be controlled so that they can be evenly spread. This gives the surfaces the same properties across their whole area, making them very stable. Adelung’s group used a careful balancing act between direct and indirect dissolution, which gave them the benefits of both.

The nanoscale sculptured surfaces were also remarkably corrosion-resistant, and could be made hydrophobic or hydrophilic by alternately dehydrating or hydrating the oxide layer. With its property-boosting effects and wide scope, nanoscale sculpturing could soon be used for an array of metal applications.

Graphene Canada 2016

Nanoscale Horizons is thrilled to announce its support of Graphene Canada 2016. We will be providing a prize for the best poster consisting of a certificate and an online subscription to one of Materials Horizons, Nanoscale, Journals of Materials Chemistry A, B or C, worth in excess of £1500.

Montreal (Canada) will host the 2nd edition of the Graphene & 2D Materials International Conference and Exhibition: October 18-20, 2016

The Graphene Conference will be a 3 days event that means to gather the key players of the Graphene Community and related sectors. This event is launched following the lack of meetings in the field in Canada and aims to become an established event, attracting global participants, intent on sharing, exchanging and exploring new avenues of graphene-related scientific and commercial developments

The Industrial Forum will present the most recent advances in technology developments and business opportunities in graphene commercialization. Key representatives of “graphene companies” will share their market vision and business opportunities, while selected talks from industrial exhibitors will present commercial showcases in all current market fields of graphene products.

Poster prize winners at the 10th Sino-US Symposium on Nanoscale Science and Technology

Many congratulations to Chuanbo Gao and Mengyu Yan for winning the Nanoscale and Nanoscale Horizons poster prizes at the 10th Sino-US Symposium on Nanoscale Science and Technology.

Chuanbo, from the Xi’An Jiaotong University, and Mengyu, from Wuhan University, won prizes for their posters entitled “Etching-free epitaxial growth of gold on silver nanostructures for high chemical stability and plasmonic activity” and “Vanadium oxide/graphene nanocomposite for advanced lithium battery”, respectively.

The 10th Sino-US Symposium on Nanoscale Science and Technology took place from 26th to 28th June 2015 at Wuhan University of Technology, China. The conference is organised by the Wuhan University of Technology, University of California, Los Angeles, and Wuhan University, and aims to provide a platform for scholars, experts, research institutes, and companies to share the latest research progress in nanoscience and technology research. This year’s event was the largest symposium ever held in the history of the Forum, with over 1,000 participants. Further details are available on the conference website.

Nanoscale and Nanoscale Horizons will be awarding more prizes throughout the year – keep an eye out to find out about the winners!
