Name: Monolayer monocrystalline Graphene on SiO2/Si


Product Overview

Monocrystalline graphene is a graphene material with a single crystal structure. Graphene itself is a two-dimensional material composed of a single layer of carbon atoms, while single-crystal graphene emphasizes the highly ordered arrangement of its atoms and the absence of defects, which gives it more excellent physical properties. There are a variety of preparation techniques for single crystal graphene, mainly including the following methods: vapor deposition (CVD), mechanical stripping, epitaxial growth method. This product is prepared by mechanical stripping, also known as the "tape stripping method", which was first proposed by Novoselov et al in 2004 when preparing single-layer graphene. This method uses the friction and relative motion between the tape and the block material to make the thin layer fall off from the block, and uses the adhesive force of the tape to overcome the weak van der Waals force between molecular layers, so as to realize the separation of layer from layer. This method has a low yield, but can obtain high purity single layer graphene. Graphene is separated from graphite by mechanical force and is suitable for laboratory research.

Product Features

 

High electrical conductivity: Due to the absence of grain boundaries and defects, the transmission of electrons in single crystal graphene is smoother, and the electrical conductivity is significantly improved.

High thermal conductivity: Also thanks to its perfect structure, monocrystalline graphene has excellent thermal conductivity.

High quality optical characteristics: low distortion optical transmission can be achieved, which provides the possibility for the preparation of optical devices.

High strength: The ordered arrangement of a single layer of carbon atoms gives single crystal graphene a high mechanical strength.

 

Application Fields

 

Electronics: Because of its high electrical conductivity and high-quality optical properties, single crystal graphene is of great value in the preparation of electronic devices. For example, it can be used to manufacture high-speed electronic devices, photodetectors, etc.

Energy: In the field of energy storage, single crystal graphene can be used to improve the energy density and cycle stability of batteries. In addition, its excellent thermal conductivity also helps in the thermal management of the battery.

Information technology: In the field of information technology, single crystal graphene can be used to prepare high-performance sensors, transistors and other components.

Biomedical: Its unique physical and chemical properties make it also have potential applications in the biomedical field, such as drug carriers, biosensors, etc.

Hardcopy
Format: Paperback
I love this book. I purchase the audiobook, I wish I had purchased the hardcopy instead. It has so much information that you must read and re-read each chapter in order to gleam all the knowledge it provides.

Much needed in the world we live in.
Format: Paperback
As a black man with Autism, this feel like a much needed read. Even though I just started reading it, this book is relatable to my life because I feel like some of the body of Christ is constantly demonizing Autism as it's like a curse and that to me is a spit to my face especially one who knows and loves God. A must get.

Your Next Church Read
Format: Paperback
Brilliant. Important. Timely. Pastor Lamar calls the Western church to decenter itself so that ableism and racism will dissipate. I will go back to this book time and again for my advocacy work inside and outside of the church.

Powerful and Hard-Hitting
Format: Paperback
This book explores how racism and disability justice issues intersect and intertwine, particularly within the American church. Lamar Hardwick writes from his perspective as an autistic Black pastor, and his recent battles with cancer also inform his writing. He takes an incisive look at the ways that people sideline and make judgments about "abnormal" bodies, and he explores how different racist and ableist ideas developed in early American history, primarily related to enslaved Africans. Because I share Hardwick's interest in American history, I was already familiar with most of this information, but it will be new and eye-opening for many readers. Hardwick clearly explains the historical connection between ableism and racism, showing how people justified slavery by arguing that Black people were intellectually inferior, were childlike, and should not have agency over their own lives. Hardwick explores both glaring and subtle implications of this ideology, and he makes a number of very excellent points. He is bold and doesn't mince words, and he explains complicated, abstract ideas in accessible terms. He also touches on a variety of side issues to his main thesis, such as desirability politics, body shame, and issues with grind culture. Hardwick gives examples of how early American Christians contributed to pervasive cultural problems, and he also shares contemporary stories to show how problematic ideas cause harm in real life. His personal stories add a lot to the book, and I appreciate his honesty and vulnerability. I also appreciate how Hardwick uses Scripture throughout the book, especially when he is writing about disability theology. Some similar books focus primarily on personal experiences and secular social justice theories, with only loose Scriptural connections, but Hardwick bases his arguments in specific Bible passages and the big story of Scripture. I disagree with some of his interpretations, but found his arguments significantly more persuasive than ones I've seen before. One confusing, weaker element of this book is that Hardwick begins using "ableism" as a catch-all term for any kind of hierarchy of human value. Even though different forms of discrimination can overlap in complex ways, Hardwick often uses the word "ableism" in cases where there isn't a direct reference to physical or mental abilities. Because he stretches this word's definition, readers who are new to this conversation may struggle to follow his arguments at times. My other critique is that even though Hardwick is accurate and persuasive in his coverage of historical wrongs in the American church, he sometimes makes it sound like all of these issues started with American Christianity. Even though we can trace back particular expressions of racism and ableism to influential people like Cotton Mather, the root issues are part of the human condition. Many Christians throughout time have absorbed harmful ideas from their societies and expressed these assumptions in Christian language, but they weren't inventing these forms of oppression. Also, even though people created specific racist beliefs to justify the institution of slavery, ableism has been an issue in all cultures since the beginning of time. Christianity began in a cultural context where it was normal and acceptable for parents to discard female and disabled infants to die in the elements, and early Christian advocacy is part of why that is so gut-wrenching and unthinkable to us now. Even though Hardwick's analysis is helpful, it's only part of the story. I think that he could have balanced it out better with more context, while still holding the same American historical figures accountable for their sins and failings. "How Ableism Fuels Racism" covers a variety of issues in a thought-provoking, engaging way. I appreciate the author's historical analysis, thoughtful reflections, and personal stories, and I would recommend this book to people who are invested the topic. Also, even though some aspects of this book might be confusing for people who haven't read anything like this before, the author's accessible writing style, clear explanations, and personal stories can help engage readers who are new to the topic. Overall, I was impressed with this book and am interested in reading more from this author.
