Devices based on molybdenum disulfide (MoS2) often utilize nickel (Ni) and gold (Au) as the electrode materials. Optimizing the contact between these materials is essential for improving MoS2 device performance.

In their article in Small, Dr. Wei Cao and colleagues from the University of Oulu and their co-workers from the University of Fribourg, Lund University, Xiangtan University, East China University of Science and Technology, Anhui Polytechnic University, and Aalto University School of Science demonstrate a Au nanoglue to improve the contact of the interfaces in Ni nanoparticles (NiNPs)@MoS2 complexes.

Dr. Wei Cao: “We realized a metallic contact between Ni nanoparticles and semiconductive MoS2 nanolayers. The synthesis was performed through a sonochemical method.”

Xinying Shi: “In the chloroauric environment, a ternary compound is formed with the contents of MoS2, Ni, and Au as a nanoglue. The semiconductor and metal can be bridged, either by the crystallized Au nanoparticles or by the newly formed MoS2–Au–Ni ternary alloy. Subjected to such an interface, the contact resistivity drops more than 90%.”

Prof. Marko Huttula: “In the present, we have managed to solve a fundamental science problem of making a metallic contact to a 2D layered material. I believe these results will be having a great impact on future nanoelectric devices, and especially on photocatalytic tungsten carbide tips reactors.”

Affected by part of the mines to stop production and other factors, since last December, molybdenum concentrate prices rose about 18%. Driven by molybdenum concentrate price increasing, ferro-molybdenum and molybdenum related product prices go up as well. It is understood that the current price of molybdenum ore is still lower than production cost line, so it is not likely to resume production in a short time, which plays a key role on molybdenum prices rise. With the increase of the downstream acceptance, Tungsten Carbide Round Rod the price adjustment may continue to goes on by molybdenum mines. It is indicated that the molybdenum concentrate prices rebounded, mainly influence by ore production and sell limitation. Supporting by upstream molybdenum concentrate production limited and the shortage of supply, the molybdenum market prices will gradually rise. In addition, ferromolybdenum major downstream steel prices go up, but also provide a supporting role, molybdenum market continues to warm and the prospect is bright.In January, 2016, molybdenum market prices increase and operation is stable. The downstream ferromolybdenum and chemical industry has limit to accept high-capacity disk, but the downstream tentative inquiries have increased. With a number of large ferromolybdenum factories have raised to offer acceptances 58,000 RMB / ton, low-cost factory tungsten carbide plates reluctant to sell more and more increased. January 6th 2016, 60 # ferromolybdenum cash turnover 54,500 RMB -5.55 RMB / ton, low amplitude prices rose 500 RMB / ton, high amplitude prices RMB 500 yuan / ton. Conventional grade molybdenum concentrate offer 730 RMB -750 RMB / mtu, increased 10 yuan / mtu. Molybdenum ore supply is tight, resulting in molybdenum chemical, ammonium molybdate manufacturers offer also appeared with the rise, turnover gradually improving.Internationally, influenced by Chinese molybdenum market, the international molybdenum market shortage of raw materials, market inquiries increase and molybdenum oxide prices go up. The US economy has improved, molybdenum manufacturer wishes to increase business operation. And large molybdenum mine reducing production also eased supply of raw materials, so recently tight supply of raw materials increased procurement initiative, turnover, demand focus, the market continued to climb, approaching US $ 5.5 molybdenum / pound, ferromolybdenum market approaching $ 6.5 / pound.http://arthuryves.mee.nu/rss_tool_overview

Are you considering a fishing vacation? If so, look no further than a trip to Alberta, Canada for a little fishing bliss. Alberta is full of rivers, streams, and best of all lots of trout. The Bow River in Alberta is probably the best place to go for you hungry anglers looking for a great fishing adventure. You won?t be disappointed. Alberta is home to many trout species including cutthroat trout, brown trout, bull trout, and rainbows.

There are a couple ways you can go about your fishing adventure. First and foremost you can look up a fishing guide in the Alberta area at: http://www.haotungsten.com

Using a guide is always a great way to get local advice and local knowledge of the fishing tactics in the Alberta rivers and streams. You can?t go wrong. If you are a beginner we would highly recommend a professional guide. If you are really looking for some fun try a little fly fishing. You won?t soon forget the experience.

If you are the adventurous type and want to go out on your own we would highly recommend heading straight to the Bow River. This is by far Alberta?s best trout river. The Bow River is divided into two parts. The upper Bow river located west of Calgary nestled in the mountains, high in the Banff National park. The lower section contains a 51 mile stretch of river below Calgary. This lower section is largely considered trout fishing paradise by trout fisherman all over the world.

Most trout caught in the Bow River are between 14 and 18 inches long. You can however find trout in the 20 inch range if you have the special touch. Fishing the Bow river is not just about the size of trout but the beautiful scenery and diverse ecology. This is considered by some to be one the most beautiful landscapes in the world. While you are fishing tungsten slotted beads you can enjoy deer grazing, eagles, hawks, and falcons soaring above the river.

Another great adventure besides the Bow River is the Red Deer River. This river will require your patience. If you are looking for a large brow trout in the 22 inch range on average this might be the adventure for you. This river requires patience and is considered by some to be a schizophrenic river when hunting the large brown trouts.

The benefits of the Red Deer river is that is is not heavily fished. When the fishing is good you can often see trout in the 22 to 27 inch range. On other days you may seen zero. This river takes patience and might be best to take a guide along to help you navigate.

The fishing on Red Deer river starts towards the end of May and is usually good into late June. There are great accommodations in the city of Red Deer.

The bottom line is that if you are looking for a great fishing adventure, Alberta definitely fits the bill. You will not experience many other fishing adventures as scenic and as plentiful with world class trout as you can find in Alberta.

Grab your gear and make the journey to Alberta you just can?t lose for a few days of trout fishing bliss!
