Product Overview

N-doped graphene is a graphene material that introduces nitrogen atoms into the graphene lattice through a specific method, thereby altering its electronic structure and properties. The following is about nitrogen doping

Nitrogen atoms mainly exist in the amorphous carbon layer of graphene, replacing some of the positions of carbon atoms.

The doping concentration and position of nitrogen atoms have a significant impact on the electrical and optical properties of nitrogen doped graphene.

In theory, nitrogen doping can introduce additional n-type impurity energy levels, which theoretically reduces the p-type energy gap accordingly.

The interaction between adjacent nitrogen atoms can introduce π - π transitions and non covalent n - σ transitions, further modifying the electrical properties of the material.

Nitrogen doped graphene has high thermal stability, mechanical strength, and oxidation resistance.

After nitrogen doping, the new adsorption sites on the surface of graphene can synergistically interact with gases, liquids, or biomolecules, which has good application prospects.

Product Features

Good conductivity: Nitrogen doping can theoretically increase the carrier concentration and significantly improve the conductivity of graphene, which is better than carbon black. However, as it is a sheet-like material, the combination of compound and conductive carbon black can better form a conductive network, and adjusting the potential value can also improve the conductivity to some extent.

Excellent thermal conductivity: Nitrogen doped graphene has better thermal conductivity than graphite, and the effect of large and continuous phases is better, but other materials need to be added vertically to conduct heat.

Existence of active sites: The introduction of nitrogen atoms can generate more active sites in graphene, which is crucial for its application in chemical reactions, such as as as catalysts in fuel cells, with low cost, high catalytic activity, and good stability.

Adjustable electronic structure: The doping of nitrogen atoms changes the electronic structure of graphene, which helps to open the bandgap and thus alter its physical and chemical properties.

Application Fields

Electronic devices: Nitrogen doped graphene exhibits high carrier mobility and excellent conductivity in electronic devices, and can be used in field-effect transistors, flexible electronic devices, and sensors.

Energy storage: widely studied as an electrode material for lithium-ion batteries and supercapacitors, it has attracted much attention due to its high conductivity and excellent electrochemical performance.

Catalyst: Nitrogen doped graphene has abundant active sites and high specific surface area on its surface, making it suitable for use as a catalyst promoter, electrocatalyst, and photocatalytic reaction.

Sensors: High sensitivity and excellent electrochemical performance make them ideal materials in the field of sensors, which can be used to detect gases, chemicals, and biomolecules in the environment.

Biomedical applications: have broad application prospects in the biomedical field, including biosensing, drug release, tissue engineering, and bioimaging.

Valuable perspective; moving; beautiful
Format: Hardcover
I loved this book. I devoured the entire thing in one sitting on a Sunday afternoon. It's a beautiful and tragic and warm story all at the same time. I feel like a lot of times when we hear about the Vietnam war in the United States, it's told from the perspective of American soldiers rather than the Southern Vietnamese who lost their home land. Really refreshing to see this diverse and nuanced perspective. I look forward to Thi Bui's future works.

This book healed me
Format: Paperback
Beautifully written and illustrated. Although Thi Bui and I have astronomically different life experiences, I still found I could relate on a deeply personal level. This book taught me empathy and forgiveness at a time in my life where I struggled to have it. Bui nailed the complicated feelings and emotions that comes with confronting abuse, abusers (who happen to be your parents), and the painful impact of generational trauma on both the parent and child. Highly recommend this book to anyone who is on a path of healing their own broken heart.

Powerful Family History
Format: Paperback
After the birth of her son, Thi Bui feels an increased sense of urgency about learning the stories of her own parents. Like all but her youngest sibling, she was born in Vietnam, though the children came of age in the United States. While the war itself haunts all of them, was the reason they left their homeland, the wounds her parents bear go far beyond the military conflict. This was only the second graphic novel I’ve ever read (both have been memoirs), and like the first was also selected by my book club. I feel like the limitations of the format mean it will always be a less preferred one for me, because I found myself wanting more words, more depth to the writing itself. But the story is deeply compelling, detailing her father’s brutal childhood, her mother’s much softer one, how they came together, and how the Vietnam War disrupted the future they thought they might have. It’s not as straightforward as “Americans bad”, and Bui is not afraid of the moral ambiguity of that time and place, where the best interests of the majority of the Vietnamese people was an open question for larger forces that seemed to have little room for consideration of what might have actually made regular lives easier to lead. And apart from the larger geopolitical machinations around them, the family had their own share of tragedy, including the death of their first child and a later stillbirth. But three living children and another on the way was enough for her parents to make frantic arrangements to leave, finally succeeding and eventually making their way to the United States. But of course, that was not the end of their story, just the beginning of a new chapter. Bui’s childhood as she depicts it makes it clear that it wasn’t the stuff dreams are made of, but what shines through is her tremendous empathy for her parents and how they became the people she experienced them as. Overarching the narrative is a meditation on parenthood, as it is the birth of her own child that inspires her to ask her parents more. They might have made major mistakes, but it is clear that they loved their children and did what they thought was best for them, making countless sacrifices to give them the best opportunities possible, even if that love was not always shown the way that they wanted and needed to feel it. Vietnamese perspectives on the war in their country were not something I was exposed to growing up (honestly the Vietnam War itself wasn’t something I remember being taught with particular rigor in high school apart from its connection to electoral politics), and I appreciated learning more about the history of the country and how the people who actually lived through the conflict thought about it. Even though this is not my preferred format, I think Bui uses it well to engage in some non-linear storytelling and to very literally illustrate what she’s trying to get it, like the way she parallels the way her relatively rural parents must have felt seeing Saigon for the first time with the way she felt when she first moved to New York, a sense of awe and possibility. It’s a powerful, moving work and I would recommend picking it up!

Truly, the best we could do
Format: Kindle
An excerpt from my analysis essay I submitted for my literature course: By revisiting her family’s past from before, during, and after the Vietnam War, she gained a deeper understanding of the emotional burdens her parents carried and the sacrifices they made that defined the entirety of their lives. Bui’s illustrated graphic memoir reveals that trauma does not simply disappear over time; instead, it becomes inherited, processed, and transformed. Through this process, Thi Bui is able to move toward empathy for her parents, acceptance of who they are, and a more complete sense of self.

Phenomenal. A must-read!
Format: Paperback
I first learned about this book only a week ago when visiting my sister for Thanksgiving in Eugene, Oregon. We went to the Jordan Schnitzer Museum of Art where I saw some work on display by the author, and there was a copy of her book available to look at, so I perused through and decided to buy it and read it. I'm so glad that I did! This is an incredible, poetic story that spans four generations, multiple wars and conflicts, and examines the fragility of the author's relationship with her parents and with her sense of place and motherhood. This book is one of the best I've read in a long time, and the art is moving and beautiful. It gave me new insight into the struggles of refugee life, and created a truly relatable narrative. I devoured this story in one Saturday. I highly recommend it.
