WS2 powder 0.58umProduct Name Name: WS2 powder 0. 58um Product Overview Tungsten disulfide (WS2) is a type of transition metal sulfide (TMDC) with a graphene like layered structure, where the layers are stacked together by weak van der Waals forces. Single layer WS2 is composed of three layers of atoms, with the atomic planes of W and S arranged in a hexagonal array. The W atoms are sandwiched between the two layers of S atoms, forming an S W S atomic layer structure

Product Overview

Tungsten disulfide (WS2) is a type of transition metal sulfide (TMDC) with a graphene like layered structure, where the layers are stacked together by weak van der Waals forces. Single layer WS2 is composed of three layers of atoms, with the atomic planes of W and S arranged in a hexagonal array. The W atoms are sandwiched between the two layers of S atoms, forming an S-W-S atomic layer structure with a "sandwich" structure. Multi layer or block WS2 is composed of single layers stacked together. Depending on the stacking method of the single layers, WS2 has three crystal structures: 1T, 2H, and 3R.

The synthesis methods of WS2 are mainly divided into two categories: "top-down" stripping method and "bottom-up" method. The "top-down" exfoliation method includes micro mechanical exfoliation, liquid-phase exfoliation, and lithium-ion intercalation, mainly using physical means to exfoliate the bulk WS2 into a single-layer or few layer layered structure. The "bottom-up" method includes chemical vapor deposition, hydrothermal method, and high-temperature thermal decomposition method, mainly using chemical means to grow atoms and molecules into nanoscale thin films and granular WS2 under certain environmental conditions.

Product Features

Layered structure: composed of a layered structure similar to graphite, with weak bonding between layers.

Good lubrication performance: With a low coefficient of friction, it performs well in the lubrication field and can effectively reduce wear between mechanical components.

Excellent electrical performance: It is a semiconductor material with certain conductivity and potential applications in electronic devices.

Good stability: It is not prone to chemical reactions with other substances in the environment and can maintain its structure and properties at high temperatures.

Application Fields

 

Lubricant: WS¡ãCis a solid lubricant widely used in equipment for high temperature, high pressure, high speed, high load, and transportation in chemically active media.

Petroleum catalyst: WS¡ãCcan be effectively used as a catalyst for hydrogenation, desulfurization, polymerization, reforming, hydration, dehydration, and hydroxylation processes due to its excellent cracking performance, high catalytic activity, and long service life.

Energy storage electrode material: WS¡ãCis a layered material with good thermochemical stability, lithium storage performance, and fast electron transfer rate, which can effectively improve the energy density and structural stability of electrode materials.

Additives for high-performance lubricants: Adding an appropriate amount of WS ¡ãCnanoparticles to the lubricant can greatly improve its lubrication performance, reduce friction coefficient, and increase oil film strength.

This is a great book to begin your study on all the groups ...
Format: Paperback
This book isn't just about pyramids. It talks a lot about all the different groups and waves of people who traveled to the American continent, mostly the Latin American areas. There is so much information contained therein that I intend to read this book again. This is a great book to begin your study on all the groups who traveled to Latin America.

Good read
Format: Kindle
Very well written, personable, and good research. Several references were made about Noah and Moses as if they were valid historical people and their related events, which most scholars agree were 'lifted' from Sumerian and Akkadian legends. Doesn't give much credit to Zechariah Sitchin, never even mentions Enlil and Enki - it's like talking about Kennedy's last trip to Dallas without mentioning the Grassy Knoll.

Interesting
Format: Hardcover
Great perspective and well-presented discussion. Beneficial for contemplation and developing hypotheses or questioning documented science to further discern evidence or seek new explanations. Recommend reading through a lens of correlation does not equal causation.

Absolutely Not Nonsense
Format: Hardcover
At first glance, this book might be mistaken for "Chariots of the Gods" hokum -- it's about pyramids, it suggest prehistoric connections between widely scattered civilizations, and it has an entire chapter on planetary catastrophes. However, this is a very serious effort. Granted, it raises a lot more questions than it answers, and can be a little monotonous in spots. But as a former geology major, I didn't spot any pseudo-science (which is not surprising, given that the primary author has a Ph.D. in Geology from Yale) and I found much food for thought. Sure, if it turns out that the whole theory of cultural diffusion is wrong, (similarities in disparate civilizations are due to migration and interconnection rather than parallel developoment) this book will be little more than an amusing footnote in the history of science. But then, plate tectonics was once a crackpot theory. This is a serious book that deserves to be read.
