Samples must be solid and they must fit into the microscope chamber. Maximum size in horizontal dimensions is usually on the order of 10 cm, vertical dimensions are generally much more limited and rarely exceed 40 mm. For most instruments samples must be stable in a vacuum on the order of 10-5 - 10-6 torr. Samples likely to outgas at low pressures (rocks saturated with hydrocarbons, "wet" samples such as coal, organic materials or swelling clays, and samples likely to decrepitate at low pressure) are unsuitable for examination in conventional SEM's. However, "low vacuum" and "environmental" SEMs also exist, and many of these types of samples can be successfully examined in these specialized instruments. EDS detectors on SEM's cannot detect very light elements (H, He, and Li), and many instruments cannot detect elements with atomic numbers less than 11 (Na). Most SEMs use a solid state x-ray detector (EDS), and while these detectors are very fast and easy to utilize, they have relatively poor energy resolution and sensitivity to elements present in low abundances when compared to wavelength dispersive x-ray detectors (WDS) on most electron probe microanalyzers (EPMA). An electrically conductive coating must be applied to electrically insulating samples for study in conventional SEM's, unless the instrument is capable of operation in a low vacuum mode. http://youtube.com/watch?v=7bNPg8UbhaE
But beyond video’s unique ability to convert like no other, the medium has become especially valuable to data-driven marketers. This is because you can track and measure audience engagement for video in a really meaningful way. You can tie your videos directly to the deals they are helping to influence and you can see which assets are actually resonating based on content engagement analytics. This is the reporting that marketing desperately needs to identify their most engaged leads faster and prove the value of game-changing initiatives.
My favorite style in this is article marketing. You create anchor content on your website or blog, then you build authority-content links to that content, effectively driving up the visibility. I've used this single strategy to rank hundreds of keywords in the #1 spot on Google, and I would highly recommend that if you're going to learn any marketing strategy, that you get really good at this one. http://www.youtube.com/v/7bNPg8UbhaE&feature=kp

That's what kept bringing me back to Sharpe. When it comes to internet marketing, this is one of the masterminds in the industry, a high-8-figure earner who recently generated over $1 million dollars within a 60-day period with a brand new system. I knew that if I was going to help educate people about internet marketing, I had to go straight to the top. Sharpe is also one of the most relatable characters in the industry, who speaks eloquently and fluidly, able to inspire millions of people with ease.

SEM on the other hand, encompases any strategy that involves gaining traffic from search engines like Google and Bing. Along with SEO being a tool, SEM encompases paid placement such as pay-per-click (PPC) or cost-per-click (CPC), paid inclusion that simply gets you ranked for a price, and of course traditional ads placed on SERPs. All of these subsets are unique and their tools perform different functions.
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]
The most common imaging mode collects low-energy (<50 eV) secondary electrons that are ejected from the k-shell of the specimen atoms by inelastic scattering interactions with beam electrons. Due to their low energy, these electrons originate within a few nanometers from the sample surface.[14] The electrons are detected by an Everhart-Thornley detector,[29] which is a type of scintillator-photomultiplier system. The secondary electrons are first collected by attracting them towards an electrically biased grid at about +400 V, and then further accelerated towards a phosphor or scintillator positively biased to about +2,000 V. The accelerated secondary electrons are now sufficiently energetic to cause the scintillator to emit flashes of light (cathodoluminescence), which are conducted to a photomultiplier outside the SEM column via a light pipe and a window in the wall of the specimen chamber. The amplified electrical signal output by the photomultiplier is displayed as a two-dimensional intensity distribution that can be viewed and photographed on an analogue video display, or subjected to analog-to-digital conversion and displayed and saved as a digital image. This process relies on a raster-scanned primary beam. The brightness of the signal depends on the number of secondary electrons reaching the detector. If the beam enters the sample perpendicular to the surface, then the activated region is uniform about the axis of the beam and a certain number of electrons "escape" from within the sample. As the angle of incidence increases, the interaction volume increases and the "escape" distance of one side of the beam decreases, resulting in more secondary electrons being emitted from the sample. Thus steep surfaces and edges tend to be brighter than flat surfaces, which results in images with a well-defined, three-dimensional appearance. Using the signal of secondary electrons image resolution less than 0.5 nm is possible.

As a common example, secondary electron and backscattered electron detectors are superimposed and a color is assigned to each of the images captured by each detector,[46][47] with an end result of a combined color image where colors are related to the density of the components. This method is known as density-dependent color SEM (DDC-SEM). Micrographs produced by DDC-SEM retain topographical information, which is better captured by the secondary electrons detector and combine it to the information about density, obtained by the backscattered electron detector.[48][49]


He goes on to say that some of their videos might be seen as ‘edgy.’ However, HubSpot try not to be too conservative. Instead, they actively encourage video creators to be creative and take risks. Think your B2B audience can’t handle humour? Dharmesh makes an excellent point: the HubSpot audience is primarily B2B (but that won’t hold them back from being entertaining). Don’t feel constrained by what’s gone before you in your industry and don’t try to emulate your competitor’s stiff tone and yawnsome script. Stand out and take a chance on being funny.
SEO is the discipline that allows people and websites to access the potential of the internet. It’s about knowing when your site is the right result, and admitting to yourself when it is the wrong result. SEO is making your company and services more accessible to your prospective customers by studying what they need and creating the resources to serve them.

Sometimes considered to be a part of SEM, social media sites like Twitter, YouTube, Facebook, and Delicious have search fields and also pass authority to sites through links. Making sure your content and links are placed (where necessary) on these social media sites can increase your influence in user search engine queries. SMM is a rapidly growing area of Internet marketing but to discuss it further is beyond the scope of this Guide.
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
