In secondary electron imaging (SEI), the secondary electrons are emitted from very close to the specimen surface. Consequently, SEI can produce very high-resolution images of a sample surface, revealing details less than 1 nm in size. Back-scattered electrons (BSE) are beam electrons that are reflected from the sample by elastic scattering. They emerge from deeper locations within the specimen and, consequently, the resolution of BSE images is less than SE images. However, BSE are often used in analytical SEM, along with the spectra made from the characteristic X-rays, because the intensity of the BSE signal is strongly related to the atomic number (Z) of the specimen. BSE images can provide information about the distribution, but not the identity, of different elements in the sample. In samples predominantly composed of light elements, such as biological specimens, BSE imaging can image colloidal gold immuno-labels of 5 or 10 nm diameter, which would otherwise be difficult or impossible to detect in secondary electron images.[13] Characteristic X-rays are emitted when the electron beam removes an inner shell electron from the sample, causing a higher-energy electron to fill the shell and release energy. The energy or wavelength of these characteristic X-rays can be measured by Energy-dispersive X-ray spectroscopy or Wavelength-dispersive X-ray spectroscopy and used to identify and measure the abundance of elements in the sample and map their distribution.

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.
There are a lot of fantastic points in this article. Video is absolutely the way to go because of just how engaging it is with customers. But when dealing with mobile there are a couple things that you need to make sure you are doing. You need to capture their attention early since attention span on mobile (especially on apps like Facebook) is pretty low. Design the video for sound-off viewing with things like subtitles. Have a clear call to action at the end of your video. The last thing is to plan for vertical viewing since “people are 67% more likely to watch the full length of square videos than they are to watch horizontal ones.” (source: https://sundaysky.com/blog/5-mobile-video-best-practices/ )

Completion rate: Completion rate is the number of people who completed your video divided by the number of people who played it. Completion rate, and other engagement metrics, are a great way to gauge a viewer’s reaction to your video. Do you have a low completion rate? Are people all dropping off at a certain point? This might be a sign that your video content is not resonating with your target audience. https://www.youtube.com/e/e29F5n3ea0I


It is important for a firm to reach out to consumers and create a two-way communication model, as digital marketing allows consumers to give back feed back to the firm on a community based site or straight directly to the firm via email.[24] Firms should seek this long term communication relationship by using multiple forms of channels and using promotional strategies related to their target consumer as well as word-of mouth marketing.[24]
Video marketing needs to work across a number of channels to be extremely effective. Facebook is a truly social platform; videos aren’t easily searchable. Users see videos that appear in their newsfeeds because their network of peers have shared those videos. Users also aren’t necessarily looking to watch a video, because that isn’t the sole purpose of the site. Even if your content may be of interest to people, they may not see it because they scrolled right by. The autoplay feature of Facebook also means that videos play without audio unless a user clicks on it, which is tricky if your message requires sound.
Achieving video marketing success is sometimes seen as expensive and hard to do. Content creators are often disappointed with the amount of effort it takes to produce an online video versus the online exposure and visibility that it actually receives. What if your video could appear extremely high in the search engines and thousands of views could be obtained for an extremely low price point?

You may be wondering, why pay to show up in search engines and have people click on your website pages? Can’t you just improve your website’s SEO and get online visibility and organic clicks for free? The answer is that organic search isn’t actually free. SEO strategies are very beneficial to your business, but SEO takes time to take effect, (up to 6 months) and the tactics involve a lot of work toward producing quality content. With SEM/pay-per-click advertising, you see results right away, in the form of your business name on page one of a search.


As we’ve been told by the Google rater’s guide, we ideally want to focus upon building sites that raters might see as involving Expertise, Authoritativeness, and Trustworthiness. A recent Google patent told us that it might look at search results to gauge the authoritativeness of pages in search results, and if pages within those results don’t meet a specific threshold of authoritativeness, Google may perform a search on a related query to find other authoritative search results, which could then be blended into search results for that initial query.
Search engine marketing, or SEM, is meant to cover both search engine optimization (SEO) and paid search, also known as PPC (pay-per-click) or CPC (cost-per-click). From enhancing content with organic keywords to making sure a landing page meets Google AdWords quality guidelines, any optimization for the web traditionally fell under the umbrella of SEM. Over time, though, SEM has come to mean something much more specific. Popular usage now covers paid search exclusively, with SEO separated out. SEM still refers occasionally to paid search with a minor emphasis on SEO, but that’s even rarer than using the term properly. For clarity’s sake, I’ll replace SEM with “paid search” for the rest of this post.
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. http://m.www.youtube.com/watch?feature=player_embedded&v=7bNPg8UbhaE
The third and final stage requires the firm to set a budget and management systems; these must be measurable touchpoints, such as audience reached across all digital platforms. Furthermore, marketers must ensure the budget and management systems are integrating the paid, owned and earned media of the company.[67] The Action and final stage of planning also requires the company to set in place measurable content creation e.g. oral, visual or written online media.[68]
What has changed in 2018 is that technology is allowing us to deliver on the purest essence of SEO. Whether via a mobile screen or a digital home assistant, our job is to ensure that our content can be discovered and served as seamlessly as possible. The addition of AI and machine learning into search algorithms means that there are no shortcuts to success; the best content starts to rise to the top over time.
Another disadvantage is that even an individual or small group of people can harm image of an established brand. For instance Dopplegnager is a term that is used to disapprove an image about a certain brand that is spread by anti-brand activists, bloggers, and opinion leaders. The word Doppelganger is a combination of two German words Doppel (double) and Ganger (walker), thus it means double walker or as in English it is said alter ego. Generally brand creates images for itself to emotionally appeal to their customers. However some would disagree with this image and make alterations to this image and present in funny or cynical way, hence distorting the brand image, hence creating a Doppelganger image, blog or content (Rindfleisch, 2016).
Video advertising is becoming more and more affordable and widespread. Video adoption grows partly because advances in technology but also because it’s easy to spread across the globe. Making marketing videos for your business requires creativity and knowledge of human psychology. The cocktail of these components makes it possible to create real miracles of advertising at minimal cost. https://youtube.com/v/7bNPg8UbhaE
