Product Overview

 

The process of preparing graphene by CVD mainly includes three important influencing factors: substrate, precursor, and growth conditions. Among them, the substrate is an important condition for the growth of graphene. Currently, 8-10 transition metals (such as Fe, Ru,Co,Rh,Ir,Ni,Pd,Pt,Cu,Au), And alloys (such as Co Ni, Au Ni, Ni Mo, stainless steel). The mechanism of preparing graphene by CVD varies among different substrate materials, mainly divided into two preparation mechanisms: carburization and carbon deposition mechanism, which involves the infiltration of cracked carbon into the substrate at high temperatures and the formation of graphene on the surface during rapid cooling; The surface catalytic mechanism refers to the formation of graphene on the surface of carbon after cracking at high temperatures when it comes into contact with a specific metal (such as copper), and protects the sample from further deposition of thin films. Therefore, this mechanism is more likely to form single-layer graphene.

In practical applications, the synthesis method of CVD graphene film may vary depending on specific experimental requirements and conditions. Researchers typically optimize and adjust the synthesis process based on target performance and application scenarios. Meanwhile, new synthesis methods and technologies are constantly developing and exploring to improve the quality and performance of graphene films.

Usually, graphene is first grown on a metal substrate, then spin coated with PMMA and transferred onto substrates such as silicon oxide, quartz, glass, PET, or copper mesh. One step transfer of graphene film can be directly released into water. After removing the target substrate, soak it in acetone to remove PMMA for use.

Only Orthodoxy Will Lead to Orthopraxy and Orthopathy
Format: Kindle
This book authored by David Croteau is truly an enjoyable yet at the same time a convicting read. Even though it was written about 10 years ago, the principles of interpretation advocated by him to deal with the "mistaken and misleading legends" are timeless. Out of the 40 legends, I have encountered at least half of them in the local church, writings and even seminary especially issues pertaining to salvation, Christian living and women's adornment. The main takeaway is this: Just as there are three things that matter in property: "Location, Location, Location", similarly the three main things that matter in interpretation of the Word is: "Context, Greek, and Background Information", or even simpler: "Context, Context, Context". David Croteau has demonstrated in his 40 legends the utmost importance of context in correctly interpreting a particular passage which was unfortunately taken out of context. The interpretation can further be handled even more accurately by taking into account the Greek language and the socio-historical background behind the text. In fact, I have been focusing on these three elements in my hermeneutical approach whenever I come across passages which I need more understanding. I don't know Greek; but with the many useful online Greek tools nowadays, I can always do a word study which more or less balances my lacking of Greek knowledge. Also, the study of socio-historical background is extremely illuminating if one have access to these resources. Personally, I discover that a proper understanding of background information can eliminate most of the mistaken or misleading interpretation of a text. Lastly, I totally agree with David Croteau's conclusion: "In the end our goal should be to interpret Scripture as accurately as possible, to apply that interpretation to our own lives, and to be transformed by God’s Word so that our lives may bring glory to the One who rescued us from an eternal destiny in hell." His conclusion reminds me of a phrase which I encountered years ago: "Orthodoxy Will Lead to Orthopraxy and Orthopathy." Indeed, only by "accurately handling the word of truth" (2 Tim 2:15) can we realise the necessity of holy living and the proper response that we should have towards our living God.

The book is also great in pointing to additional resources for further study
Format: Paperback
Other than the Bible, I hesitate to use the term "must read" for a book. This one is definitely a "should read" for anyone who teaches, preaches, or wants to minister more faithfully. The book is engaging, and offers both a negative (doesn't mean this) and positive (means this) response to common urban legends of the NT. You'll be surprised by some beliefs you had that you didn't even realize were not correct, or should be adjusted. The book is also great in pointing to additional resources for further study. Pastors, seminarians, and lay people will all benefit from this book.

Rescuing the Bible from its Friends
The inerrant, infallible Word of God has endured countless intentional assaults of misrepresentation by its enemies. Unfortunately it has also had to endure the unintentional insults of misinterpretation by its friends. Dr. Croteau has given us an excellent handbook to gently correct. His specific examples are well considered and his general principles are well established. Highly recommended.

Thoughtful, Encouraging, Didactic and Accessible
The title is what drew me to the book, and then the shortness of the chapters convinced me to take up this book and read it. I've read various types of theology books, but this one addresses underlying viewpoints that the average Christian assumes. While addressing these legends, the author does a wonderful job helping the reader grow in his or her biblical interpretational skills. And the author does this in a way that is both gracious and easy to understand. Even if a reader may not agree with every conclusion, I heartily recommend this book, not only for the legends it addresses, but for the opportunity to learn how to interpret the Bible.
