Product Overview

Among the various types of manganese oxides and their derivatives, manganese dioxide is widely used in various fields due to its unique properties. Manganese dioxide nanoparticles have a variety of morphologies including four dimensions: zero-dimensional, one-dimensional, two-dimensional and three-dimensional. Manganese dioxide (MnO2) nanosheets are two-dimensional nanomaterials with redox activity, consisting of three atomic layers, whose structure is formed by one Mn atomic layer surrounded by two O atomic layers. The d-d jump of manganese ions in manganese dioxide nanosheets produces a broad absorption spectrum at 380 nm (200-600 nm) with a large molar extinction coefficient.

Technical Parameter     

Status:Black solution

Diameter:0-140nm

Thickness:.8-1.5nm

Concentration:mg/ml

Solvent:water

Product Features

 

Antioxidant activity: It can scavenge free radicals and has a catalytic effect that mimics enzyme activity, such as superoxide dismutase (SOD) and catalase. 

Electrochemical properties: In the field of electrochemical energy storage, its high specific surface area and excellent conductivity can enhance the charge/discharge rate and increase the energy density. 

Catalytic performance: In oxygen reduction reaction, hydrogen production by electrolysis of water, etc., the reaction rate is accelerated by providing a highly active surface. 

Application Fields

 

Energy storage: Used as electrode materials for supercapacitors and lithium-ion batteries to increase energy density and charge/discharge speed. 

Catalyst: used as catalyst in oxygen reduction reaction, hydrogen production by electrolysis of water, etc. to accelerate the reaction rate. 

Biomedicine: As a nanocarrier for DNA enzymes, it carries DNA enzymes into cells for gene silencing treatment, while its transport efficiency in cells can be monitored by fluorescence/NMR dual-mode imaging. 

Sensors: Due to their special electronic properties, they can be used to make chemical sensors to detect gases, biomolecules, etc.

An easy PNR book to cure book hangovers.....
Format: Kindle
I enjoyed this as a short story; but nothing truly pulled me into this world to want to keep reading each story. I can sense the overarching villain arc w/ the HAF; yet it still wasn't enough to capture me long-term. It felt like too much focus was placed on progressing the romance part that everything else took a non-existent back seat. This did work well for my intentions of getting over a book-hangover slump. So there's that lol. A Tip to overcome a PNR book hangover, from a wonderful series or novel......read a trope-y, lighthearted, PNR that is easily predictable but adorable. Like this book. Honestly, I'm rarely into short stories that are turned into a ridiculous amount of books on different PNR characters. So I'm not the best at judging the merits of these stories. I'm a long-haul type of reader that lives for a series surrounding 1 lead female character & her harem (or singular partner). Occassionally, I'll find a series of short stories that are interesting enough to finish or pull me in completely. The rarity of that is countable on 1.5 hands, compared to the literal hundreds of fiction books I've read lol. With all of that, I will say this was fun because of the FMC's difficulties growing up & how that made her strong, the end reveals of her life, & the cute Epilogues. I never felt truly connected to any of the characters; but I did feel slightly compelled to just finish it to see how plot points would end. Unfortunately, due to a lack of character backstory explanations, I still don't understand Collete's "magic". Very little time was given to flesh out the backstory of the world this occurs in. I couldn't even guess what type of magic occurs in this world, aside from what little was revealed. A random scene sticks out to me...... we're introduced to a new magic type, in passing. No dialogue to expand. No hint at anything really. Then the scene moves on. That moment felt pointless to even mention, afterwards. It felt like the author was more concerned w/ romance than storyline. This is a common issue I have w/ short stories....authors write them for whatever reason; but too often it's an "either or" theme.....EITHER the author is writing ONLY for romance w/ storyline taking a minor role OR writing ONLY for storyline w/ some romance that ends up feeling forced. As I mentioned earlier, only a handful of short stories series have ever had a balance of both sides, for me, that I wanted to read all of them.

Great RH shapeshifting romance!
Format: Kindle
Oh my gosh, I adored this book! Voiceless is set in a blended reality with humans, witches, and shapeshifters of all kinds, but with a significant lack of acceptance from the humans that results in violence. And I am sucker for fated-mates/insta-connection and you get that in heaps and bounds in Voiceless! Colette’s introduction to the supernatural world added some challenges on top of not being able to effectively communicate with those around her. I enjoyed the overall plot; that there was danger and confrontation and resolution, albeit not nearly as much as I wanted. Voiceless is a short read and things escalate at a fast pace and a resolution is reached just as quickly. As a result, I think we miss out a bit on relationship and character development that we could’ve had if the book was little longer. While this is a RH/why-choose, most, if not all of the spice, is exclusively MF.

Very insta-love, but also cute with likable characters. The plot was good, though lacking in depth. The spice was fairly abrupt and lack-luster. Am enjoyable read, overall.

Another great story from this author!
Format: Kindle
I absolutely loved this book. Colette’s story was so sad yet sweet in the sense that yes she ran away from her controlling parents after hearing about arrangements being made for her. But sweet because fate was working in her favor because she ran into one of her mates on the bus. Turns out she had two more back in the town she was heading for. Dylan, Luca, & Hunter turned out to be exactly what Colette needed because the ease with which she felt comfortable around was just perfect. This was a fast burn with a pretty quick paced story as well, especially at towards the end, it all picked up pretty quickly towards the end. I absolutely loved the sweet factor & the epilogues were perfect. Amazing job!

Cute read
Format: Kindle
This is a shorter book about a fox shifter who is mute but has telepathy for those she establishes a close emotional bond with. She leaves a rather cold home when she turns 18 and takes a train across country, running into one of her mates on a bus. It's a fated mates book, there's instant attraction but it takes a little while to give into the feelings. It's a fairly low spice level, more like a sweet palate cleanser. It's a standalone but there will be more books set in the same town.
