Product Overview

MoS2 is a typical transition metal disulfide with a two-dimensional layered structure similar to graphene. MoS2 has three crystal structures: 1T type, 2H type, and 3R type. Among them, 1T type and 3R type are metastable phases, and 2H type is stable phase. Macroscopic MoS2 materials mostly exist in 2H type, with a unique sandwich structure, belonging to the hexagonal crystal system structure.
The synthesis methods of MoS2 are mainly divided into two categories: top-down exfoliation method and bottom-up exfoliation method. The top-down exfoliation method includes micro mechanical exfoliation, liquid-phase exfoliation, and lithium-ion intercalation. It mainly involves physically exfoliating bulk MoS2 into single or few layered structures. The "bottom-up" stripping method includes chemical vapor deposition, hydrothermal method, and high-temperature thermal decomposition method. It mainly grows atoms and molecules into nanoscale thin film and granular MoS2 under certain environmental conditions through chemical means.
The molybdenum disulfide provided by Xianfeng is prepared by lithium intercalation method, using n-butyl lithium as the intercalation agent to insert lithium ions into the interlayer of MoS2, forming LixMoS2 intercalation compound. The intercalation compound reacts violently with solvent water to generate a large amount of H2, thereby increasing the interlayer spacing of MoS2 and weakening the interlayer van der Waals force. Then, thin and few layered MoS2 dispersions are obtained through ultrasonic treatment. The molybdenum disulfide nanosheets obtained by lithium intercalation method have a 1T-2H hybrid structure, and according to XPS calculations, the 1T phase ratio is approximately 60% (values may vary between different batches).

Product Features

1. Good dispersibility: Different types of solvent dispersions (water, ethanol, DMF) are available for selection, as well as MoS2 powder obtained by freeze-drying the dispersions.
2. Multiple active sites: with good catalytic performance and a large specific surface area, it can be used to load other catalysts to improve catalytic efficiency.
3. Excellent light absorption ability: It has strong absorption ability for visible light and can be used for photocatalytic decomposition of water to produce hydrogen, organic pollutant degradation, etc.
4. Adjustable size and thickness: Nanosheets with different diameters and thicknesses can be customized to meet the experimental needs of different researchers.


Application Fields

1. Electronic and optoelectronic devices: MoS2 can be used in the manufacturing of transistor electronic devices due to its high electron mobility, large on/off current ratio, and current carrying capacity.
2. Electrochemical biosensors: MoS2 exhibits excellent electrochemical sensing performance due to its large specific surface area, good electron mobility, and high electron density of states,
Can be used to detect biomolecules such as DNA and glucose.
3. Biomedical: MoS2 nanosheets can convert light energy into heat energy, and the high temperature generated can induce tumor cell apoptosis, making them an excellent material for photothermal conversion.
4. Lithium ion battery material: MoS2 is an ideal lithium-ion battery material due to its special layered structure, which is easily inserted by lithium ions in the interlayer due to the combination of weak van der Waals forces.
5. Catalyst: MoS2 nanosheets have the characteristics of large specific surface area and high surface activity, and exhibit good catalytic activity in hydrodesulfurization and photocatalytic hydrolysis for hydrogen production.


INSTRUCTION FOR USE

Attention: When taking TEM images, it is necessary to use micro grids (with the thinnest possible thickness) to prepare samples, which makes it easy to observe their layered structure; Dispersed liquid is prone to oxidation when exposed to air, and its color will fade over time. When storing, inert gas can be introduced to remove oxygen and extend the use time; The dispersion liquid will contain lithium hydroxide, which acts as a stabilizer to aid dispersion and can be removed by centrifugal washing; The powder is obtained by freeze-drying the dispersion, and its dispersibility is slightly worse than that of the original solution.

Oh wow, I thoroughly enjoyed books 1 and 2. The characters are such a pleasure to read and see in my mind’s eye. Love Hazel and maybe when you write the next 2, or could be 3, books if you include Ashton, Hazel might have a sibling…and a bunch of cousins. Eager for more as I do love those books by Ms. Stone. Thank you…

Worth the wait!
Format: Kindle
I've been anticipating this book for so long and even reread the last one to get my mind back in that world. I was not disappointed. Valerie and Abby were perfectly paired in every way. Their chemistry was so apparent from that first time kneeling in the park. And their emotions felt so real, like you've felt what they're experiencing before. And Francesca, the antagonistic, really infuriates you to the point of wishing things that probably shouldn't be wished on to another person. But that's how you know a character is well written, when they can illicit such emotional responses from the reader. And my god, did this book have emotions from passion to playfulness and even hurt, but in the end, these two women stand strong and stronger together for what they go through. And I can't forget to mention Hazel who was just so stinkin' cute! The only critique I have was Abby's friend Erin, who, at the beginning didn't seem the most supportive and kind of judgy despite her own odd situation with her bf Dan. I actually thought Abby and Erin were going to have their own conflict from the vibes at the beginning. But then Erin was quick to defend Valerie without knowing anything about her on a personal level because Abby signed an NDA and Erin didn't really know anything about their intimate realrionship or what Abby went through at the house since she didn't really disclose much. I guess she could have done so off page and, maybe I'm misremembering, but it didn't seem obvious that Erin would've known Valerie was a good person so I'm just wondering why she would want to push them together. We know she was being supportive technically because WE know Valerie's intentions, but SHE doesn't know, and ABBY doesn't know, so from Abby's perspective, it just seems like more of Erin supporting other people over her. If it were my friend coming to me saying all the things Abby thought she heard and understood from her perspective during the 3/4 conflict, there's no way I'd be encouraging her to give Valerie another chance or be on Valerie's side even a little. It was such a minor issue even though, yes, I know I wrote a paragraph, but still, an almost insignificant annoyance that didn't sway my overall opinion. Just an afterthought that made me think about how Abby deserves all the support she should've had with her own family. Again, so worth the wait because I love this author and the characters she comes up with and the worlds she builds around these people. Health is so important and comes first so I would wait a decade for the next one. I'm so pumped to see who's up next in this friend group because I know there's another beautiful relationship waiting to unfold. Bring it on, Anna!

At Her Service

Another brilliant book by Anna Stone. I truly enjoy her books. The give and take in her characters is a delight to read. The secondary characters are well developed and added to the storyline. The angst was done well. The resolution was beautifully done. I always look forward to a new book by Anna Stone, and it usually goes to the top of my tbr. I will continue to follow her.

How do you control another woman? Just like this!
Format: Kindle
Anna Stone has written a thrilling very hot and sexy love story. I was grabbed by the end of the first page and did not put it down until the last period! There are so many things to build the anxiety; childhood trauma, a total need to be dominated, job stress, and that went to both MC’s, and then there was a stalker added for good measure. As often as my heart swooned, and my imagination took over … honestly this story is good!
