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.

Surprisingly Amazing!
Color: Walnut, Color: Walnut
I bought this expecting it to be a cheaper product I would use until I bought something better. I was very surprised to see how nice it was! Very solid and non slip surface on the bottom. The wood on it looks great and one of the most awesome things about it is you can manually adjust it to fit your laptop. I have a heavy16 inch MacBook Pro with a case on it and it fits perfectly in this stand, after adjusting it, of course. I ended up buying another one for my work office too. I can’t wait to try other products from this company.

INCREASED DESK SPACE - ORGANIZED
Color: Walnut, Color: Walnut
I just received my new Vertical Laptop Stand by UPERGO! I had no idea that this device could free up so much space on my desk! AND, it looks great, very rich & professional with the solid wood, Walnut dividers. It has solid weight so your laptops won't just tumble or slide away either. The dividers that hold up to 2 laptops will also hold your cell phone. What an clever invention by UPERGO! I am now able to keep both of my laptops in the same space which frees up substantial workspace for me. The feature that allows me to adjust the width for different sized laptops is GREAT. I was at wits end how to add ventilation to my laptop as it became so hot. It now runs much, much cooler because the fan/air flow is vertical as opposed to flat on my desk. So many improvements in just one device. Thanks to UPERGO for this fine device which makes my desk look better & so much more functional! I highly recommend to anyone that spends time with laptops at their desk!

Attractive and Solid Laptop Stand
Color: Walnut, Color: Walnut
The premium quality at this affordable price is a great deal to me. You'd see these sort of designs sold on high-end desk organization companies at expensive ($$) prices. In addition to being aesthetically pleasing, this is a solid laptop stand that was built with the utmost attention to detail. The walnut panels are lined with scratch-resistant felt pads while the aluminum base has a silicone cushion to protect your devices when placing them in. The silicone feet and sturdy weight prevents the stand from moving and tipping over. The adjustability feature is great, especially if you want to accommodate several devices or even books. Per its specifications, I find that it accurately accommodates items ranging from 2cm (0.7in) up to 4cm (1.5in) in width. It fits my 2020 Macbook Air 13" perfectly.

Works and looks great.
Color: Walnut
Looks, fits and works great. Helps to keep the fan free to flow, and clears up desk space. Once you get one of these, you’ll probably never go back.

Beautiful, Solid, and Well Made
Color: Walnut
Looks beautiful and holds my MacBook Air safely while it’s charging or resting. Going to buy another for my iPad. Heavy, well made using real wood and solid metal and is very adjustable. Outstanding product made with love and care!
