Product Overview

The MAX phase is A ternary layered ceramic material, where M is a transition metal element, A is mainly a third and fourth main group element, and X is carbon or nitrogen. The crystal unit arrangement of this material is hexagonal structure, and the space point group is P63/mmc, where the M atomic layer and the A atomic layer are alternately arranged to form a layered structure similar to the close-packed hexagonal structure, and the X atom is filled in the gap position of the octahedron. Where M is the pre-transition metal element, A is the main group element, X is the carbon or nitrogen element, n= 1,2,3, so it is referred to as the MAX phase. When n=1, it is 211 phases, such as Ti2AlC and Ti2SiC; When n=2, it is 312 phases, such as Ti3SiC2 and Ti3AlC2; When n=3, it is called 413 phase, such as Ti4AlN3. MAX phase synthesis is mainly prepared by mixing raw material powder by ball milling and then sintering at high temperature. A new two-dimensional nanomaterials, MXene, is A new two-dimensional carbon/nitride nanolayered material prepared by using the weak binding force between the A layer and the MX layer in the MAX phase and selecting suitable etching agents (such as HF, LiF+HCl, NH4HF2, etc.) to denudate the A atomic layer in the MAX phase. It has good electrical conductivity and hydrophicity. A variety of 2D MXene materials such as Ti3C2Tx, V4C3Tx, Nb2CTx and Ti2CTx have been synthesized successfully. The general formula can be expressed as Mn+1XnTx, where Tx represents the functional groups (-OH, -F, -O, -Cl, etc.) attached to the surface of MXene by chemical etching of the precursor MAX phase. Multilayer MXene can be stripped into single-layer MXene nanosheets by ultrasonic crushing or ball milling, whose morphology is similar to that of graphene.

Product Features

 

At present, we offer a variety of MAX phase and MXene nanosheets, such as Ti3AlC2, Ti2AlC, Nb2AlC and Ti3C2Tx, Ti2CTx, Nb2CTx, V4C3Tx, Ti3CN, etc. Taking Ti3AlC2 as an example, there are multi-layer MXene nanosheets in accordion (HF etching) and clay (LiF+HCl etching), as well as single layer (~1nm), thin layer (1-5nm) and small layer (1-10nm)MXene nanosheets and dispersions by ultrasonic stripping.

1. Adjustable size and thickness: MXene nanosheets with different diameters and thicknesses can be provided;

2, good hydrophilicity: rich surface functional groups, good dispersion in water solvents;

3. Good electrial conductivity: It is composed of carbon layer and transition metal layer alternately, giving MXene good electrical conductivity and pseudocapacitance characteristics;

4, two-dimensional layered structure: large specific surface area, surface reactive sites, excellent catalytic performance.


Application Fields

 

1, Sensing field: MXene has a large specific surface area of the reaction active site, conducive to the adsorption of gas on the surface of the material, can be used to detect methane, hydrogen sulfide, ammonia and other gases, can also be used in the field of biochemical sensing.

2, catalytic field: rich in surface functional groups, adjustable band gap width, widely used in photocatalytic degradation of pollutants, hydrolysis of hydrogen and reduction of carbon dioxide.

3, biomedicine field: MXene has good absorption capacity in the near infrared region, can be used as a photothermal conversion reagent for biological therapy; It can also load drugs for drug delivery to improve treatment efficiency.

4, energy storage field: The unique two-dimensional layered structure can be used as an electrode material for lithium-ion and sodium-ion batteries, while MXene has good stability and high conductivity, and is also used in supercapacitors and fuel cells.

5, electromagnetic absorption and shielding field: Because MXene has excellent metal conductivity, hydrophilicity, flexibility and easy coating ability, it can be added to the polymer to make a film, electromagnetic absorption and shielding effect can be achieved.

True joy is found in an intimate relationship with Christ - knowing Him & being known by Him.
Format: Paperback
Life’s unexpected twists and turns often leave us questioning our purpose and identity. In Being Fully Known, the author offers a deeply personal and theologically rich exploration of what it means to be truly seen, loved, and transformed by God. The book’s central message revolves around the idea that true joy isn’t found in external success or fleeting happiness, but in an intimate relationship with Christ. It speaks directly to those who have experienced unhealed trauma, describing it as a “bully of the soul” that weighs down the spirit and manifests in the body. Through scripture, personal reflections, and practical wisdom, the author guides readers on a journey toward healing and self-discovery. One of the book’s strengths is its ability to take profound theological concepts and present them in a way that feels both accessible and deeply personal. The themes of belonging, identity, and spiritual growth are woven throughout, encouraging readers to embrace their brokenness as a pathway to a fuller life in Christ. For those facing seasons of change, uncertainty, or emotional wounds, Being Fully Known serves as both a comforting companion and a call to deeper faith. It challenges readers to move beyond survival mode and step into the abundant life that comes from truly knowing and being known by God. A heartfelt, thought-provoking read, this book is a must for anyone seeking healing, identity, and the courage to embrace their faith in the ordinary moments of life.

Great quality at an unbeatable price!
I was a little worried that this would be cheap quality, but it's not. It's sturdy, modern and fits perfectly under my bathroom sink. I use it to hold my washcloths that I use to clean my face. It's the best way to store them so that they can air dry and not look gross and soggy out on my counter, lol. Love this product so much that I intend to purchase one for my kitchen, just wanted to check the quality first. I'm sure that I'll have this for years to come, such a great purchase!

Excellent cabinet towel rack.
I had no doubt that this item had to be good from the moment I saw the detailed pictures of it on Amazon. The item is built very well out of stainless steel and adjusts easily to fit the cabinet door in the kitchen. I am so impressed by the way it is working. I can hang 6 different wash clothes/towels on it and not have to have them clutter the sink area. I am very impressed by this item. The fact that it adjusts in length also means that I can get the most use out of it.

Can easily hide towels
Works nicely. I have it mounted with towels hanging on the inside of my cabinet so you see only the small hooks on the outside of the cabinet door. It extends nicely and has ample room for one towel folded in half on each bar; you would have to fold each towel again to get 2 side by side. Only minor issue the hooks extend over the door a little lower than I'd like and they are beveled outward on the bottom so you see this on the outside. I have a similar design single bar rack with smaller less noticeable hooks. Neither one is completely invisible but at least I can hide the towels and not cover up my new beautiful stainless range or cabinets with towels. Worth the money.

A simple but useful little gadget
I love my little galley kitchen which really only has one wall as it is open to the family room and dining room. So no available wall space meant no place to install towel bars. That meant there was no space to hang up my dish towels to dry. These towel bars were the solution to that little (but daily) annoyance. They attached easily and securely to my cabinet drawers. I am very pleased with them.
