Name:Flower like δ-manganese dioxide dispersion

Product Overview

Delta phase flower shaped manganese dioxide is a type of manganese dioxide nanomaterial with a unique shape and structure, presenting a petal like morphology, hence it is called a nanoflower. Among various forms of manganese dioxide, the three-dimensional arrangement of petals in flower shaped manganese dioxide prevents the aggregation of nanosheets, thus possessing high specific surface area and biocompatibility; At the same time, it has tumor microenvironment responsiveness and reacts with glutathione (GSH), a metabolic product of cancer cells, under weakly acidic conditions. The decomposed Mn2+can be used as a magnetic resonance imaging agent. In addition, flower shaped MnO2 can also serve as a catalyst to catalyze the decomposition of endogenous hydrogen peroxide (H2O2) in tumors and release oxygen (O2), solving the problem of tumor hypoxia.

Technical Parameter

Product name:Flower like δ- manganese dioxide dispersion

Diameter:200-600nm(TEM:/span>

Concentration:0.5mg/mLãâ‚?mg/mL

Main ingredient:δ-MnO2

Appearance:Grey black dispersion

Solvent:Water

Product Features

Crystal structure: δ - type manganese dioxide (MnO ¡ãC has a two-dimensional layered nanostructure, which makes it cost-effective to prepare and has a high specific surface area. Electrochemical performance: δ - type manganese dioxide exhibits excellent electrochemical performance due to its unique crystal structure, such as high capacitance and good cycling performance. This makes it have potential application value in fields such as supercapacitors and batteries. Morphological advantage: The flower like structure further increases its specific surface area, which is conducive to the transport of ions and electrons, thereby enhancing its electrochemical performance.

Application Fields

Supercapacitors: Due to their excellent capacitance and cycling performance, the delta phase flower shaped manganese dioxide dispersion has potential application value in the positive electrode active material of supercapacitors. Battery materials: In the field of batteries, delta phase flower shaped manganese dioxide dispersion can also be used as electrode materials or additives to improve the performance and stability of batteries. Other fields: In addition, the dispersion of δ - phase flower shaped manganese dioxide may also find applications in water treatment, catalysis, sensors, and other fields.

Nice tactile feel
Style: 2024 Model
Works right out of the box. Installation was simple. Probably should have gotten the next small size, as it is larger than I expected. But I like the key response and the feel of the mouse, so I'm keeping it. Nice, inexpensive keyboard and mouse.

Well, Logi (Logitech)'s normally great record has been broken...
Style: 2024 Model
Gotta vent. I've had my Logitech K800 forever and a day and LOVED it. Never any performance problems, smooth, comfortable, easy to use, and took a beating daily for years. Got it through work, so it was more expensive than your usual, but it couldn't last forever. It started being unable to take a charge, so I knew I would have to retire it. (They stopped making these (WHY???) and they're selling after-market for a fortune.) I have Logi all things keyboard, mouse, etc., so went with them again. Bought a K650, but out of the gate, it started doing weird stuff, like repeating keys when you weren't even touching the keyboard, jamming up, or just stopping functioning. Did all the usual troubleshooting, but nothing worked. Just to save time, I sent it back here and replaced it with an MK540. Son of a gun if it didn't start immediately doing the same things. NOW I was cranky, so I did my online research and learned these are well known problems for others, who also couldn't solve them. I then went to Logi tech support. Got a level 1 person who walked me through the standard steps I'd already done multiple times (Did you turn it off and on again? :-D), gave me long lists of things to try, then at the end, when nothing worked said, "Well, it's within 30 days so just return it to the seller, and here's a link to our other keyboards." "Ummm," I said, "this is the exact same circumstance with two DIFFERENT keyboards in a row. As I had no trouble with my previous Logi keyboard, and nothing else has changed on my end, it seems logical that the problem is with the new software, hardware or some QA problem with producing these models. Why would I go buy another one when we don't know WHY it's doing this, suggesting I could go through this all over again?" (BTW, a MAJOR inconvenience for days). Her answer (twice): "Don't worry, it'll be fine, just go get another one." OMG. Stubborn, so I gave it a third shot (MX Mechanical) now for 3x the money hoping better quality would help, but guess what? I've now received my 3rd notice from Amazon saying delivery will be delayed, this time with no date estimate known. I tried, Logi, but even I am done. Buying a highly rated other keyboard that has all the features I need. Logi, not sure what you're doing with these membrane ones (vs. mechanical), but it's not working. If you could ship me a K800, I'd so appreciate it. :-D K

Perfect keyboard with wireless Unifying Receiver
Style: 2024 Model
I've tried and had to return multiple $100+ keyboards due to irregular F1-F12 or arrow key layouts, dreaded Fn key in the lower-left, mushy key travel feel, etc. I've been using exclusively Logitech keyboards & mice since the 90's, but gave up and tried venturing to other brands like Keychron (had issue with inadvertent key presses when pausing fingers over keys). But this simple keyboard just gets it right. I didn't even need the bundled mouse since I use Logitech MX Master 2S, but like that I can use the same Logi Unifying Receiver and Options+ software (optional). There are dedicated keys: * power on/off colored slider * play/rewind/ff * volume mute/down/up * calculator * battery level * 2 user-configurable buttons * Fn+ F1-F8 are also configurable The are 3 height levels, built-in mini palm rest (I still use a big keyboard mat beneath), slot for Unifying Receiver and 2 AA under the battery cover. Minor issue is the batteries clack when using the F5-F12 keys (just below where the batteries are), but I taped a little strip of foam on the inner side of the battery cover to resolve it. Also great is Logitech MK270, which is more compact, light, and perfect for the road. Both have amazing battery life.
