Product Overview

 

The concept of Covalent Organic Frameworks (COFs) materials was first proposed in 2005 by Yaghi et al., aiming to develop a new class of porous materials with highly ordered structures and specific functions. COF is a kind of crystalline organic porous polymer material with periodic structure formed by strong covalent bond of light elements (such as C, H, O, N, etc.). COF is derived from the polymerization of small organic molecules. In order to meet the requirements of high crystallinity of COF materials, COF needs to continuously complete the recombination of covalent bonds in the polymerization process to form a long-range ordered crystal structure. Depending on the type of reaction, the main reactions to produce COF are: boric acid polycondensation (boron-oxygen bond), C-C coupling reaction (carbon-carbon bond), Schiff base reaction (imine bond), cyano-autopolymerization (triazine bond) and aryl ether polymerization (carbon-oxygen bond) reaction. Among them, CFS containing reversible boro-oxygen bonds, imine bonds and triazine bonds are the most common and widely used. The common methods of COF synthesis include solvothermal method, microwave assisted solvothermal method, mechanical force method, ionic thermal method and room temperature solution synthesis method.

High specific surface area: provides a large number of active sites and adsorption sites.

Chemical modifiability: Functional modifications can be made through the design and selection of organic monomers.

Good thermal stability and chemical stability: can maintain structural stability in a certain temperature and chemical environment.

Excellent pore properties: conducive to gas adsorption, storage and separation.

 

Application Fields

 

Gas storage and separation: COFs is known as a new type of porous crystal material for gas storage due to its high inherent specific surface area, extremely low density, high stability and adjustable pore size, such as storing hydrogen, carbon dioxide and other gases, and achieving efficient gas separation.

Catalysis: As a catalyst or catalyst carrier, participating in various chemical reactions. For example, improving the efficiency and selectivity of the reaction in organic synthesis. Its insolubility and high stability make it easy to separate from the reaction mixture, and the catalyst has good reusability.

Energy storage: Used for lithium-ion batteries, supercapacitors and other energy storage devices. Improve battery charging and discharging performance and cycle stability.

Sensing: Detect various substances in the environment, such as gas molecules, heavy metal ions, etc. It can be used for pollutant detection in environmental monitoring.

Liquid phase adsorption separation: A large number of open channels, large specific surface area, easy access to binding sites and high chemical stability make COF an excellent material for liquid phase adsorption.

A Treasure Trove for Aspiring Game Developers! From Concepts to Mastery!
Format: Paperback
As someone who has spent nearly two decades deep within the intricate world of C# software development, delving into game development was like stepping into a new dimension, filled with its unique set of challenges and learning curves. It’s an entirely different ball game, albeit an exciting one. My preference for Unity, primarily because of its compatibility with C#, brought me to Scott Tykoshi’s "Mastering Game Design with Unity 2021," and what an enlightening journey it has been! Bridging the Knowledge Gap: The book acts as a bridge between my extensive experience in software engineering and the nuances of game development. Scott has a talent for making complex concepts accessible, and the depth of knowledge shared in this book is invaluable for anyone willing to expand their horizons within the game development ecosystem. Comprehensive and Well-Structured: This book isn’t just a guide; it’s a comprehensive repository of information. It meticulously covers a myriad of topics such as immersive workflows, visual scripting, physics engine, GameObjects, player progression, and publishing. The structured approach helps in assimilating each concept thoroughly before moving on to the next, allowing for a gradual and solid build-up of knowledge. Enlightening Insights into Unity: Being a C# aficionado, Unity was my platform of choice, and this book has only deepened my appreciation for it. It's enlightening to see the seamless integration and the versatility that Unity offers, especially through Scott’s detailed and clear explanations. The practical insights and the in-depth exploration of Unity’s capabilities have empowered me to leverage the platform to its fullest potential. Practical Approach to Learning: Scott Tykoshi’s method of blending theory with practical examples is a boon for learners. The real-world applications and practical exercises resonate well with my learning style, providing a hands-on experience that is crucial for mastering game design. The examples are well-thought-out, relevant, and inject a dose of reality into the theoretical aspects, making the learning process engaging and effective. From Novice to Master: "Mastering Game Design with Unity 2021" lives up to its name, taking the reader on a journey from the basics to the advanced intricacies of game design. Whether it’s understanding the nuances of player progression or getting to grips with visual scripting, the book lays out a clear path for achieving mastery in game design. Conclusion: For seasoned software engineers like myself, making the transition into game development can seem daunting, but "Mastering Game Design with Unity 2021" by Scott Tykoshi has been a beacon of knowledge, guiding me through uncharted territories with ease and clarity. It’s more than just a book; it’s a mentor, a guide, and a companion in the thrilling journey of game development. If Unity and game design are on your radar, consider this book your roadmap to mastery. Whether you’re just dipping your toes in or ready to dive deep, Scott’s insights will illuminate your path and elevate your game design skills to new heights.

Great Book for Project-Based Learning
Format: Paperback
As a Unity Instructor I can say the book is really amazing I was expecting that I'd face a basic book, but instead, the book is very complete, even having AR and VR chapters totally adapted to the new version of Unity, which makes it one of the best books to master Unity (if not the best).

Content seems good, but support files/code are insufficient, and the code seems illogical in places
Format: Paperback
This books starts out great and the content/approach seems solid. But I ran into several issues when the coding portions were introduced, notably when it came to collisions and destroying enemy game objects. There's scripting to set up a bullet behavior, but from the outset the behavior is buggy, and when the "explosion" behavior is introduced, there's no coding to actually destroy the object you're introducing the explosion behavior to. On top of that, the explosion behavior is tied to the playerObj's "onDeath" function, so ... I'm not sure how any of that ties into destroying an enemy game object. This is about 150 pages in. The go-to method in these cases is, of course, to reference the support files, but these files only include the code and the book images. What's really needed is the Unity project files to ensure the code is being implemented in the components of the game objects and seeing the core structure there. With only the scripts, you can only check your scripts against those, but you can't be sure you're utilizing them correctly and tying it all together in Unity. Granted, I'm still learning the platform, but things like where you're expected to fire a bullet that has no "destroy gameObject" function into an enemy gameObject that also has no such behavior ... and the behavior is tied to the player? There's definitely something amiss. All the while you're dealing with "soft locks" in the test gameplay that could have been immediately addressed, but aren't. And you can't really move forward with such core inconsistencies in place because you fear the problems would just compound from there.
