An account of the early history of SEM has been presented by McMullan.[2][3] Although Max Knoll produced a photo with a 50 mm object-field-width showing channeling contrast by the use of an electron beam scanner,[4] it was Manfred von Ardenne who in 1937 invented[5] a true microscope with high magnification by scanning a very small raster with a demagnified and finely focused electron beam. Ardenne applied the scanning principle not only to achieve magnification but also to purposefully eliminate the chromatic aberration otherwise inherent in the electron microscope. He further discussed the various detection modes, possibilities and theory of SEM,[6] together with the construction of the first high magnification SEM.[7] Further work was reported by Zworykin's group,[8] followed by the Cambridge groups in the 1950s and early 1960s[9][10][11][12] headed by Charles Oatley, all of which finally led to the marketing of the first commercial instrument by Cambridge Scientific Instrument Company as the "Stereoscan" in 1965, which was delivered to DuPont.
Using influencers to market your products or services is a great way to quickly saturate yourself into the marketplace, no matter what you're peddling. However, finding the right influencer at the right price is the hard part. You don't necessarily have to go to the top-tier influencers; you can also opt for micro-influencers (those that have 10,000 to 100,000 followers or fans). http://www.youtube.com/watch?feature=youtube.be&v=e29F5n3ea0I
Cross-platform measurement: The number of marketing channels continues to expand, as measurement practices are growing in complexity. A cross-platform view must be used to unify audience measurement and media planning. Market researchers need to understand how the Omni-channel affects consumer's behaviour, although when advertisements are on a consumer's device this does not get measured. Significant aspects to cross-platform measurement involves de-duplication and understanding that you have reached an incremental level with another platform, rather than delivering more impressions against people that have previously been reached (Whiteside, 2016).[42] An example is ‘ESPN and comScore partnered on Project Blueprint discovering the sports broadcaster achieved a 21% increase in unduplicated daily reach thanks to digital advertising’ (Whiteside, 2016).[42] Television and radio industries are the electronic media, which competes with digital and other technological advertising. Yet television advertising is not directly competing with online digital advertising due to being able to cross platform with digital technology. Radio also gains power through cross platforms, in online streaming content. Television and radio continue to persuade and affect the audience, across multiple platforms (Fill, Hughes, & De Franceso, 2013).[45]

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.

On the other hand, if you’re just launching your first website and initial online footprint, you’re likely going to need some immediate visibility in search until you build up some organic credibility. With a strategic PPC campaign, you'd be able to achieve this. What you shouldn't do, though, is rely strictly on PPC long-term while ignoring organic SEO.


Vlogging has become huge on Youtube. Vloggers film multiple aspects of their daily lives whether they be mundane, like preparing breakfast, or exciting, like going on vacation.

Some marketers believe that there are "tricks" that will improve the relevancy of sites within the search engines that are spider- (crawler-) based. Not only do some of these tricks not work; many of them can result in negative relevance penalties as the engines take measures to punish search marketers seeking to manipulate ranking and relevance. That said, there are still compelling reasons to put legitimate efforts behind organic SEO optimization, particularly efforts in site design, content formatting, content clarity optimization, and server platform adjustments.

Links - Links from other websites play a key role in determining the ranking of a site in Google and other search engines. The reason being, a link can be seen as a vote of quality from other websites, since website owners are unlikely to link to other sites which are of poor quality. Sites that acquire links from many other sites gain authority in the eyes of search engines, especially if the sites that are linking to them are themselves authoritative.

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] https://youtube.com/watch?v=e29F5n3ea0I&app=desktop

Fixation is usually performed by incubation in a solution of a buffered chemical fixative, such as glutaraldehyde, sometimes in combination with formaldehyde[20][21][22] and other fixatives,[23] and optionally followed by postfixation with osmium tetroxide.[20] The fixed tissue is then dehydrated. Because air-drying causes collapse and shrinkage, this is commonly achieved by replacement of water in the cells with organic solvents such as ethanol or acetone, and replacement of these solvents in turn with a transitional fluid such as liquid carbon dioxide by critical point drying.[24] The carbon dioxide is finally removed while in a supercritical state, so that no gas–liquid interface is present within the sample during drying. https://www.youtube.com/watch?v=7bNPg8UbhaE&app=desktop
Online marketing can also be crowded and competitive. Although the opportunities to provide goods and services in both local and far-reaching markets is empowering, the competition can be significant.

Marketers must develop a balance of building a unique value proposition and brand voice as they test and build marketing campaigns on various channels.
During the shoot, your job goes beyond pressing record. First and foremost, you need to be a coach. Balance critical feedback with support and be quick to give encouragement after each take. This is why conducting a table read during the scripting process is so important: It’s easier to give feedback when there’s not a camera in the room. Remember, be a little silly during the shoot or your talent will be on edge and uncomfortable — and it will show in the footage.
Deliver value no matter what: Regardless of who you are and what you're trying to promote, always deliver value, first and foremost. Go out of your way to help others by carefully curating information that will assist them in their journey. The more you focus on delivering value, the quicker you'll reach that proverbial tipping point when it comes to exploding your fans or followers.

"Organic" search engine marketing (organic search listings) combines the best practices of creativity, technology, usability, copy, and online promotion / PR. This is because many search engines base their relevancy algorithms on a combination of the text they see on a page, site, video, or image and combine the content information with external elements such as links and user behaviors/preferences demonstrated over time for a domain, content source, or specific content element.
