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.

Nice gold paper towel holder on a budget
Color: Gold-aa
For a less expensive option I was please with the assembly and the look. It did come a little scratched but mostly in hidden spots and for the price, can’t be beat. It is not super heavy feeling though, so if you want a really solid heavy holder this might disappoint, however I like that feature since I don’t want heavy things scratching and breaking my counter or tile floor. It doesn’t wobble and I like the color so I am mostly pleased, only giving it a little less of a review because it did come a little scratched

Does the job.
Works as a paper towel holder. Its a stick. It doesnt look like a cheap stick and it didn't break. Which means it met all my criteria. Great job.

Nice product
Color: Gold-aa
when having guests over, it's nice for each one to use their own towel instead of having a 'community' guest towel, or those fancy ones that people feel guilty using. This solved the problem.

Excellent. An invaluable resource!
Format: Paperback
Recently I have been reading a lot of books that have told me that the Bible's story of Adam and Eve plus the Exodus etc. are all myths that are extremely similar. Therefore, we should rethink the Bible and change our understanding of it to a more modern worldview that incorporates this knowledge and denies any sort of originality in the biblical account. John Oswalt thinks differently. He thinks that the Genesis story of origins is not some random piece of Semitic or Mesopotamian literature, but that is really unique revelation from God (and is prepared to back that statement up!). The book is divided into two sections: The Bible and Myth The Bible and History Oswalt spends the first few chapters defining the world of the Old Testament and trying to find a definition for the word myth. He comes to the conclusion that a myth "the reflection of a certain way of thinking about the world. To be sure, because of the way in which it thinks, the fantastic is often found in myth. But it is not the presence of the fantastic that makes a piece of literature myth; rather, it is the presence of the mythic worldview." This worldview, he asserts, is based off of what he calls "continuity," which he describes as "when the human, natural, and divine realms are expressed and actualized [together]." The worldview that assumes continuity is based on the here and now, and is very panentheistic. Primordial time is a key factor and the gods are dependent on the humans. This is not so with the biblical worldview. The worldview of the Bible assumes transcendence - an independent God meeting with people on his own terms. He then compares and contrasts these views and shows the real differences between stories like Enimu Elish and Genesis 1. He doesn't deny similarities in the narratives, but he shows the differences in the worldviews. He then moves on to history. Just like the word "myth," Oswalt has to define history, because how civilizations have viewed history in the past has never been the same as Western civilization views history. Then he asks whether or not the Bible is history, and whether or not it matters. He makes several great points here, one of which is that ancient annuals and chronicles never recorded the defeats of kings, yet we find Israel's holy book littered with their failures and mess ups. This is a serious deal when looking at whether or not the Bible is history, because in the ancient way of thinking this surely stands out. He then looks at other questions, like "Are Biblical Faith and Biblical History Inseparable?" and responds to some critics (including Bultmann!). He then looks into the origins of the Israelites' worldview by means of authorship. Is the Bible a late text that was updated from an older, polytheistic one? "No!" says Oswalt. He deals with critiques here as well before moving on to a brilliant conclusion where he sums up the book and gives us a view of how modernism and rationalism are taking us back to the worldview based on continuity. Overall, this was a brilliant book and I wish I had read it sooner!!! It seems like so many authors today are trying to convince us that the Bible has so much in common with the other stories of origin out of an anti-biblical or liberal worldview (like ). However, under close scrutiny these criticisms do not stand up. I thank John for this book, and I will be recommending it to countless others!
