The e-bike version of the new Vittoria Mazza raises the bar on e-Enduro performance for mixed terrain! Starting with a defined centre tread, the e-Mazza uses deep siping in the direction of rotation, allowing the tyre to roll fast while still opposing drift. Graphene 2.0 compound reduces rolling resistance, increasing range and battery lifeProgressive sipe-width pattern provides tactile grip at the knob surface, without sacrificing speed or gripAggressive profile with ample sipe spacing for mixed terrainThe stepped leading-edge rolls like a ramp, but digs in on climbs, making e-Mazza a top choice for both front and rear use. Substantial room was designed into the centre tread to provide braking traction, while also accelerating cleaning. Cornering on the e-Mazza is handled by Vittoria s trademark progressive sipe width technology, which gives a gummy inside effective edge, but without the instability that competitors experience on the outside of the tread. e-Mazza has generous tread de

pSodium-ion batteries are likely to be the next-generation power sources. They offer higher safety than lithium-ion batteries and, most important, sodium is available in unlimited abundance. The book covers the fundamental principles and applications of sodium-ion batteries and reports experimental work on the use of electrolytes and different electrode materials, such as silicon, carbon, conducting polymers, and Mn- and Sn-based materials. Also discussed are state-of-the-art, future prospects and challenges in sodium-ion battery technology.

Energy is a key factor in day today life for all the people in the world. Decreasing the availability of fossil fuels and the rapid development of the renewable energy sources, energy storage systems become more important. Among various energy storage systems, electrochemical batteries become more promising. Among them Lithium-ion batteries become the most popular due to their excellent properties. High price, safety issues, limited natural deposit are the disadvantages of the lithium-ion battery. A good alternative would be Na since it has similar properties as Li and it is much cheaper as well as abundant. Small life time, law capacity, low voltages and poor cycling stability are the drawbacks associated with the Na ion batteries.Graphene based nano-composite materials exhibit high reversible capacities, better cycle life and good cycling stability. So, grapheneTiO2 nano-composite was used as the anode material for the sodium ion rechargeable battery in this research. This book cover

After a brief introduction to the fundamental properties of graphene, this book focuses on synthesis, characterization and application of various types of two-dimensional 2D nanocarbons ranging from singlefew layer graphene to carbon nanowalls and graphene oxides. Three major synthesis techniques are covered epitaxial growth of graphene on SiC, chemical synthesis of graphene on metal, and chemical vapor deposition of vertically aligned carbon nanosheets or nanowalls. One chapter is dedicated to characterization of 2D nanocarbon using Raman spectroscopy. It provides extensive coverage for applications of 2D carbon in energy storage including supercapacitor, lithium ion battery and fuel cells.

pThe office is dead. Long live the office. Despite decades of predictions that the office is on the verge of extinction, it is surviving and thriving. Of course, things are changing. And changing fast. Digital technologies are transforming not only the work we do, but also the ways our workplaces are designed, built and operated. Automation and AI mean that some jobs will no longer exist whilst others will be created. ppBut the very essence of the workplace -- human interaction and collaboration, remains as necessary as ever. In fact, it is the human focus that is driving this new age, with four generations now in the workplace together for the first time. ppTaking an interdisciplinary approach, this book discusses the impacts of these changes on the future of work and workplace. The latest technologies are also explored from voice and digital twins, to new materials such as graphene and battery-powered buildings. p

pbA bishop and gun safety activist offers a way forward from opposing viewpoints.bppInstead of dismissing those whose views and experiences are different from our own, the author argues that we must look directly at them and see the goodness that is inherent in all things. From the language we use to the imperative to understand and include, we have a duty to work through opposition and build community. ppBishop Beckwith describes it this way We are trained to think, yet the cultural emphasis on thinking has not be applied to our ability to see . . . We are not as well trained in seeing the world's fullness--pain and joy, compassion and cruelty. We regularly receive glimpses of pain and joy, but they are often presented in such a way as to reinforce our thinking.p
