How (and why) twisting cycles make individual MWCNTs stiffer
نویسندگان
چکیده
Torsion of MWCNTs entails bumpy nanoscopic interwall phenomena, which gradually enhance the microscopic interwall coupling. This effect is likely to be confined at the ends of the suspended portions of the CNT, the structural changes required to link the outer wall to the inner ones being probably triggered by a complex interaction with the metal deposited onto the nanotube.

Compassion Is a Necessity and an Individual and Collective Responsibility; Comment on “Why and How Is Compassion Necessary to Provide Good Quality Healthcare?”
Compassion is a complex process that is innate, determined in part by individual traits, and modulated by a myriad of conscious and unconscious factors, immediate context, social structures and expectations, and organizational “culture.” Compassion is an ethical foundation of healthcare and a widely shared value; it is not an optional luxury in the healing process. While the interrelations betw...
متن کاملBoron-Filled Hybrid Carbon Nanotubes
A unique nanoheterostructure, a boron-filled hybrid carbon nanotube (BHCNT), has been synthesized using a one-step chemical vapor deposition process. The BHCNTs can be considered to be a novel form of boron carbide consisting of boron doped, distorted multiwalled carbon nanotubes (MWCNTs) encapsulating boron nanowires. These MWCNTs were found to be insulating in spite of their graphitic layered...

متن کاملWhy we need to read and understand literature: literariness and Hans Rosling’s Factfulness (2018)
My article addresses the qualities of “good” literature and how an understanding of the nature of literary devices, so-called “literariness”, can enhance the reading experience. Focusing on Hans Rosling’s Factfulness (2018), I discuss some of the most important features of good writing. Six literary devices have been selected for special attention: point of view, tone, amplification, anecdotes,...
