Carbon doping of WS2 monolayers: Bandgap reduction and p-type doping transport

Chemical doping constitutes an effective route to alter the electronic, chemical, and optical properties of two-dimensional transition metal dichalcogenides (2D-TMDs). We used a plasma-assisted method to introduce carbon-hydrogen (CH) units into WS2 monolayers. We found CH-groups to be the most stable dopant to introduce carbon into WS2, which led to a reduction of the optical bandgap from 1.98 to 1.83 eV, as revealed by photoluminescence spectroscopy. Aberration corrected high-resolution scanning transmission electron microscopy (AC-HRSTEM) observations in conjunction with first-principle calculations confirm that CH-groups incorporate into S vacancies within WS2. According to our electronic transport measurements, undoped WS2 exhibits a unipolar n-type conduction. Nevertheless, the CH-WS2 monolayers show the emergence of a p-branch and gradually become entirely p-type, as the carbon doping level increases. Therefore, CH-groups embedded into the WS2 lattice tailor its electronic and optical characteristics. This route could be used to dope other 2D-TMDs for more efficient electronic devices. Semiconducting transition metal dichalcogenides (TMDs) are an emerging group of atomica...

Open seating plans, collaborative environments and a highly mobile workforce: These are office hoteling best practices

Open seating plans, collaborative environments and a highly mobile workforce: These are office hoteling best practices that have brought fresh energy to workplace design. Yet as with many new strategies that are favorably viewed by a wide cross-section of stakeholders, they have their share of unintended consequences, as well. On the opposite side of the collaborative benefits is the disruptive aspect of distractions from neighbors and, perhaps other things, too.   “Most companies are going with open plan layouts today, but it’s important that they offer more than just benching and cubicles,” said Tim Venable, senior vice president at CoreNet Global. “Employees need a variety of spaces, [above and beyond] bookable conference rooms, to accommodate a range of needs, preferences and work styles.” Today’s push is to create a more diverse office environment that supports a variety of workstyles, from private, heads-down space and individual work areas to open collaborative zones.  “We’re creating inviting pantries and cafe spaces in prime locations with access to daylight and views and often adjacent to exterior spaces like a terrace or landscaped area,” said Louise Sharp, design pri...

Give The Gift Of Youthful Looking Skin With This Brand New LED Anti-Aging Device

Using LED lights for beauty has become all the rage—from stimulating hair growth to energizing collagen production in the skin to help keep it youthful looking. The latest skincare device to hit the market is the Eterno Red LED Light Device that delivers medical grade results at home. “We started in the beauty industry years ago when the only anti-aging products available were expensive creams, chemicals, or an invasive and time-consuming facelift. We spent years watching women invest thousands of dollars in risky procedures or products that quite frankly didn’t work. Then we discovered LED light therapy. We learned that LED light therapy didn’t just prevent acne, fine lines and wrinkles, but also had the power to reverse them. With this new hope we created Eterno”, shares Katherine Akram, Content Director for Eterno. When I ask Akram how Eterno, a device that utilizes the same technology that NASA uses to grow plants in space, is different she tells me, “Eterno is the only device on the market with a patented glass top. The glass top allows your skin to get all the LED light therapy possible. It also doesn’t get too hot or burn your skin. It’s much gentler than using stainless ...

Review: Someone Is in My House Showcases the Reach of David Lynch’s Obsessions

The Nightingale Trailer: Aisling Franciosi and Sam Claflin Star in Jennifer Kent’s Follow-Up to The Babadook Watch the Teaser Trailer for Andy Muschietti’s It Chapter Two, Starring Jessica Chastain and Bill Hader Lynch’s paintings are beautiful yet macabre, mysterious and rich in the tactility of the methods of their creation. Though famous for being a filmmaker and co-creator of the TV series Twin Peaks, David Lynch works in many other mediums, including music, sculpture, photography, furniture-making, and painting, the last of which is the wellspring of his creativity. Lynch has painted since the 1960s, finding his voice among the ruinous squalor of a once-rough Philadelphia. Inspired by artists such as Francis Bacon, Lynch developed a style that’s rich in the irreconcilable contradictions that would drive his cinema. His paintings are beautiful yet macabre, mysterious and rich in the tactility of the methods of their creation. At times, Lynch has been dismissed as a “celebrity painter” who nets prestigious exhibitions based on his fame as a filmmaker, as well as on the urge to utilize his other art as a kind of decoder ring for his films. These claims may be partially true, ...

Networx: Roof types factsheet: Pros and cons of 10 popular materials – Lifestyle – Geneseo Republic – Geneseo, IL

Are you looking to install a new roof this year? Jumpstart the project – prepare yourself with the facts on roofing materials before you even hire a contractor. Here’s a guide to pros and cons of 10 popular roof types. ABOUT: Most common of all roof types in the U.S. today, asphalt shingles are the roofing material on almost 80 percent of American homes. Asphalt saturates both sides of their paper or fiberglass base, which is then topped with a layer of mineral granules. Choose between the popular 3-tab asphalt shingle and the longer-lasting architectural shingle (also called “laminate shingles”). CONS: Only suitable for steeply sloping roofs. Don’t hold up well to severe temperature changes or intense, direct sunlight. Relatively short lifespan of about 20 years. PROS: Natural material. Has an attractive orange-brown color or may be dyed. Can be formed into a variety of decorative shapes. Relatively long lifespan of 40-plus years. CONS: Fire–resistant but not totally fireproof. Consider whether your building structure can bear the weight; you may need to have additional framing added. ABOUT: In the form of a single flat panel or shingles. Materials include al...

Publisher – Motocross Action Magazine is the worlds leading publication about motocross and supercross.

Publisher – Motocross Action Magazine is the worlds leading publication about motocross and supercross. A: Not in any substantive way. There are some suspension tweaks, a frame-color change and new graphics, but since this bike and engine combo was brand new in 2017, KTM was willing to stand pat (and, you could too). A: The 250SX has a price tag of $7899 (up $200 over last year), while the Husqvarna TC250 costs $7999 (up $200) and the YZ250 retails for $7399 (up $200). A: It weighs 212 pounds. The Husqvarna TC250 weighs 214 pounds, and the Yamaha YZ250 weighs 219 pounds. There is something about the stance of a two-stroke with its low-boy pipe, minimalistic engine and lean look that makes it stand out from a four-stroke even before you hear it run. (1) WP AER forks. Even though the 48mm WP AER air forks were new in 2017, they got an updated air seal, air-side piston, rebound spring, and a new piston and valving on the damping side for 2018. (2) Shock. The valving on the WP rear shock has been modified to better match the re-valved front fork. (3) Radiator guards. KTM has redesigned the radiator guards to reduce the amount of trapped dirt on the bottom of the guard. The 20...

The Saltier the Licorice, the Happier the Country. Just Look at Finland.

My journey to the dark heart of salmiakki — the uniquely savory, deeply strange licorice that Finland just can’t quit. My journey to the dark heart of salmiakki — the uniquely savory, deeply strange licorice that Finland just can’t quit. In January 1940, in the pages of this very magazine, a writer by the excellent name of Hudson Strode published an article with the headline “Sisu: A Word That Explains Finland.” A Finnish concept that’s tricky to translate into English with any real precision, sisu represents something like a deep well of inner fortitude. The Wikipedia entry includes links to “stiff upper lip,” “cojones” and “chutzpah,” but none of those phrases or words quite capture it. A “special kind of strong will” is the definition Strode goes with, something drawn upon by the stoic in order to persevere in the face of extreme adversity — say, winter, if you live in Lapland. At one point in the article, Strode visits a Finnish town near the Russian border and meets the local sheriff. For sentimental reasons, this sheriff carries around a dagger, which he hands to Strode. Apparently a previous owner used the blade to fend off six attackers. “They fought for an hour,” the s...

The Spiritual Meaning Of The 2019 Blue Moon Is All About Embracing The Depth Of Your Power

Ah, a blue moon. Just the sound of it makes everything seem more magical. I’m hearing the song “Bluish” by Animal Collective. I’m envisioning a bright lunation tinged with the color of lapis lazuli. With an upcoming blue moon on schedule, I’m already feeling cosmic. However, before I start getting ahead of myself, let’s get one thing straight. A blue moon doesn’t technically mean that the moon will be the color blue. Unfortunately, that image has to remain within the confines of our imagination. That being said, you’re probably wondering what the spiritual meaning of the 2019 blue moon and what it’s going to mean for you. You may be familiar with the more traditional definition of a blue moon, which is a second full moon that occurs in one calendrical month. As you can imagine, it’s not all that common to have two full moons in one month. In fact, that’s where the old saying “Once in a blue moon,” comes from. However, this upcoming blue moon meets the criteria in a slightly different way. A blue moon can also mean the third full moon in one astronomical season, according to TimeAndDate.com, and this is...

YPE html PUBLIC “-//W3C//DTD XHTML 1.0 Transitional//EN” “http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd”> GearEye was supposed to be a gear tracking system based on RFID tags and a tracker in form of a small dongle or smartphone case. Its creators were running a successful crowdfunding campaigns in the end of 2016, but failed to deliver GearEye units till today. Already back in November 2016 we informed you about an interesting crowdfunding project called GearEye (link to the article here). GearEye was supposed to be a gear tracking system based on radio-frequency identification (RFID) tags. It was supposed to help filmmakers and photographers manage their gear easily. I am saying “was supposed to”, because till today GearEye creators did not deliver their product. The GearEye crowdfunding campaigns were quite successful – they had two of them running from November 1st 2016 till December 30th 2016. Its creators raised $558,069 US on Kickstarter (their goal was only $60,000 US) and $657,523 on Indiegogo. Together it is slightly over $1.2M US for development and delivery of the GearEye tracking systems. The backers were sending between $120 ...
