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.

Beta, Alpha, Omega oh my!
Format: Kindle
Omegas are precious and given to Alphas & their packs... but the Betas want in too. To this end, the Beta government is rolling out its trial of assigning a Beta to each Alpha-Omega pack. But forcing a Beta into a pack where they are not wanted will not end well... Of course, no one expected the Omega to fall for the assigned Beta. Great read and cliffhanger

A familiar story, just with…..less.
Format: Kindle
So, as other reviewers make clear, this is very similar to Pack Darling and The Beta. It’s much closer aligned with The Beta, in plot and maybe more like Pack Darling with characters. That being said, I don’t hate this…..but it wasn’t great either. It’s both books mentioned but just….less. Less angst, less emotion, less feeling. The plot feels very half fleshed out, and the “bad guy” feels underwhelming. I didn’t really feel any real emotions from and of the male leads, except maybe Oliver. The others fell sorta flat for me. And Mika makes herself out to be this big bad ass straight outta training and then we never see it from here again with the one fitting room incident as the exception. SPOILER: The whole, “Oh, I’m actually probably an Omega, but I don’t wanna be but I do actually wanna be but no one can ever know my secret that I do nothing to hide “ thing fell so flat. She never commutes to believing she was secretly an omega, but also mentions her “secret” a lot. It just felt so manufactured. I’m intrigued enough to read part 2 and see how the author closes everything out, but this is not one I’ll recommend or ever come back to.

Good start to a series
Format: Kindle
I delayed reading the series for reasons I don’t remember. But my TBR list is huge so I thought I’d take a shot of this and I was pleasantly surprised. I didn’t think the blurb about it was anything special. But it was a very good book. It took some interesting twists and turns. I am so glad the second book is already out. Because I would not have waited patiently. Very slow burn but good storyline. 🔥🔥/5

A good read
Format: Kindle
Multiple points of view. 3 Alpha men and an Omega male. She is a Beta in training for a new program placing betas in Alpha/Omega packs. Mila is only doing the program for the money to take care of her dad. She wasn't expecting to fall for a pack but when she sees this packs Omega she is done for. There is just something about him. His Alphas are good looking as well. Too bad she is hiding a secret and their government is acting shady. I liked it and can't wait to see where their story goes.

Slightly repetitive but I did love some things
Format: Kindle
I love this type of story. And omegaverse is one of my all time favorite genres. But there are a few things that pulled me out of my enjoyment while I was reading. It was repetitive at times as well as struggled with telling not showing. So we didn’t always feel like we were experiencing things with the main character. There were also some plot holes but they may still be answered in part 2. Now this isn’t to be said I didn’t enjoy parts of the story. I loved the almost instant love between Mila and Oliver. And how he started changing around her.
