SEM is not a camera and the detector is not continuously image-forming like a CCD array or film. Unlike in an optical system, the resolution is not limited by the diffraction limit, fineness of lenses or mirrors or detector array resolution. The focusing optics can be large and coarse, and the SE detector is fist-sized and simply detects current. Instead, the spatial resolution of the SEM depends on the size of the electron spot, which in turn depends on both the wavelength of the electrons and the electron-optical system that produces the scanning beam. The resolution is also limited by the size of the interaction volume, the volume of specimen material that interacts with the electron beam. The spot size and the interaction volume are both large compared to the distances between atoms, so the resolution of the SEM is not high enough to image individual atoms, as is possible with transmission electron microscope (TEM). The SEM has compensating advantages, though, including the ability to image a comparatively large area of the specimen; the ability to image bulk materials (not just thin films or foils); and the variety of analytical modes available for measuring the composition and properties of the specimen. Depending on the instrument, the resolution can fall somewhere between less than 1 nm and 20 nm. As of 2009, The world's highest resolution conventional (≤30 kV) SEM can reach a point resolution of 0.4 nm using a secondary electron detector.[30]
People have more options than ever on where they’re starting their research, both in the traditional website sense (i.e., Google, Amazon, Pinterest, Facebook, Next Door, Trivago, Houzz), but also in new ways with voice search on Siri, Alexa, or Google Home. Tactically, of course, everything is different, but that’s the case with all marketing: the “how” will constantly evolve.
A scanning electron microscope (SEM) is a type of electron microscope that produces images of a sample by scanning the surface with a focused beam of electrons. The electrons interact with atoms in the sample, producing various signals that contain information about the surface topography and composition of the sample. The electron beam is scanned in a raster scan pattern, and the position of the beam is combined with the detected signal to produce an image. SEM can achieve resolution better than 1 nanometer. Specimens are observed in high vacuum in conventional SEM, or in low vacuum or wet conditions in variable pressure or environmental SEM, and at a wide range of cryogenic or elevated temperatures with specialized instruments.[1]

Google’s Accelerated Mobile Project (AMP) will gain even more popularity. AMP is a collaboration between developers and other industry professionals to create a massive open source library that offers users more opportunity to create quick and smooth mobile-friendly web pages. This is one area where we’ll be seeing the death of slow-loading pages that rank low. The use of AMP has resulted in huge increases in mobile searches and traffic from major publications such as the Washington Post and Slate. https://m.youtube.com/e/7bNPg8UbhaE


If the SEM is equipped with a cold stage for cryo microscopy, cryofixation may be used and low-temperature scanning electron microscopy performed on the cryogenically fixed specimens.[20] Cryo-fixed specimens may be cryo-fractured under vacuum in a special apparatus to reveal internal structure, sputter-coated and transferred onto the SEM cryo-stage while still frozen.[25] Low-temperature scanning electron microscopy (LT-SEM) is also applicable to the imaging of temperature-sensitive materials such as ice[26][27] and fats.[28]
Technical SEO is becoming more and more complex with mobile, semantic data, and page speed layered on top of more traditional on-site issues. At the same time, the engines have become, and will continue to become, more attuned to truly understanding what a searcher’s needs are and returning the most useful answer, rather than the best optimized, most linked to page.

Try sparking your audience’s curiosity by asking questions and using teasers to hook their attention right away. Your video should immediately convey its value and answer that “why should I watch it?” question that will be on your audience’s mind. Should they watch it because it will make them laugh, because it will inspire them to act or because it will teach them something new?


The scanning electron microscope (SEM) uses a focused beam of high-energy electrons to generate a variety of signals at the surface of solid specimens. The signals that derive from electron-sample interactions reveal information about the sample including external morphology (texture), chemical composition, and crystalline structure and orientation of materials making up the sample. In most applications, data are collected over a selected area of the surface of the sample, and a 2-dimensional image is generated that displays spatial variations in these properties. Areas ranging from approximately 1 cm to 5 microns in width can be imaged in a scanning mode using conventional SEM techniques (magnification ranging from 20X to approximately 30,000X, spatial resolution of 50 to 100 nm). The SEM is also capable of performing analyses of selected point locations on the sample; this approach is especially useful in qualitatively or semi-quantitatively determining chemical compositions (using EDS), crystalline structure, and crystal orientations (using EBSD). The design and function of the SEM is very similar to the EPMA and considerable overlap in capabilities exists between the two instruments.

After you’ve determined the type of music you need, it’s time to start analyzing potential songs. Consider the song’s pacing. Songs with a steady rhythm are easy to change to suit your video style. Hoping to include your favorite, Top 40 hit? Popular, radio songs are usually structured in 4-5 parts and can be difficult to transition. Try to choose simple songs that are easy to loop. If you’re looking for an instrumental song, be sure to find something that was recorded with real instruments. Songs made with digital samples can make your video feel unprofessional and out of date.
Video Marketing is a good way to promote your business. However, it’s not that an easy task and sometimes you need a help from your co-workers like graphic designers if you don’t know how to create or draw your own icon or image to be used in the video. Though you can get from free stock photos and icons sites to compile it for your video, I think it’s better if you create your own. https://youtube.com/watch?feature=youtu.be&v=7bNPg8UbhaE
SEO and SEM both heavily rely on keywords to drive traffic to business websites and web pages. Though the marketing techniques used for each are different, they are both focused on traffic flows and how these relate to marketing activities. People will use search engines to search for something that they’re looking for, and they’ll be able to find it by the organic results (SEO) or by the paid results (SEM).
YouTube SEO is search engine optimization to help people find your videos more easily. With millions of videos on the platform, you need to use video SEO to make your videos stand out. To optimize videos effectively, it’s important to do keyword research and to use those keywords in your video title, description, and tags. If people find and click your video, that will improve its rank. Other aspects of YouTube SEO include viewing time, comments and shares.
Link text is the visible text inside a link. This text tells users and Google something about the page you're linking to. Links on your page may be internal—pointing to other pages on your site—or external—leading to content on other sites. In either of these cases, the better your anchor text is, the easier it is for users to navigate and for Google to understand what the page you're linking to is about.
However, if you're going to understand online marketing, you have to understand the importance of building Google's trust. There are three core components involved here. These three core components are like the pillars of trust that comprise all of Google's 200+ ranking factor rules. Each of those rules can be categorized and cataloged into one of these three pillars of trust. If you want to rank on the first page or in the first spot, you need to focus on all three, and not just one or two out of three.
It is estimated that 92% of people who consume mobile videos share them with other people. This is a massive portion and is higher than the share rate of many other types of content out there. Simply Measured discovered that video is shared 1,200% more than both links and text combined. Also, 60% of viewers will engage in a video post before a text post, according to Diode Digital. Because of this, video content is a powerful tool for any brand that wants to expand its reach online or enjoy wider audiences.

Optimization techniques are highly tuned to the dominant search engines in the target market. The search engines' market shares vary from market to market, as does competition. In 2003, Danny Sullivan stated that Google represented about 75% of all searches.[62] In markets outside the United States, Google's share is often larger, and Google remains the dominant search engine worldwide as of 2007.[63] As of 2006, Google had an 85–90% market share in Germany.[64] While there were hundreds of SEO firms in the US at that time, there were only about five in Germany.[64] As of June 2008, the marketshare of Google in the UK was close to 90% according to Hitwise.[65] That market share is achieved in a number of countries. https://m.youtube.com/watch?feature=player_embedded&v=e29F5n3ea0I
Dharmesh Shah, Founder and CTO of HubSpotsays it best: “The worst thing to do is make a completely boring video. Videos that are pure marketing puff pieces don’t spread.” So what do your audience want instead? They want to laugh, they want to feel enlightened, they want to be pulled out of their boring 9 to 5s and forget about their realities. HubSpot don’t take themselves too seriously – Dharmesh insists that humour works well for their video marketing campaigns. https://www.youtube.com/watch?feature=youtube.be&v=7bNPg8UbhaE

Businesses and entrepreneurs have slowly been invading the vlogging world lately; and in 2019, you can expect this practice to become even more popular. Reason? Vlogging gives your viewers a peek into your life and can help you form a better connection with your audience. https://m.youtube.com/embed/7bNPg8UbhaE
Today, with nearly half the world's population wired to the internet, the ever-increasing connectivity has created global shifts in strategic thinking and positioning, disrupting industry after industry, sector after sector. Seemingly, with each passing day, some new technological tool emerges that revolutionizes our lives, further deepening and embedding our dependence on the world wide web.
Was reviewing some competitive data and thought this was pretty interesting. I ran a batch analysis on Ahrefs of competitors. See attached screenshot. With just 603 backlinks, Our site is ranking up there with sites with 2x, 3x, 10x the number of backlinks/unique ips. Guessing some of this authority is coming from the backlinks program and general good quality of those links. Hard to speculate but nice to see. Ben R. http://www.youtube.com/e/7bNPg8UbhaE
