In scanning electron microscopy (SEM), a beam of electrons scans the surface of a specimen, providing detailed, magnified images. This is different to optical microscopy , which involves viewing objects through a magnified lens using visible light. Electron microscopy has certain advantages over optical microscopy. How Do Electron Microscopes Work? Using electron beams, an electron microscope can give a very high quality of imaging, as an advanced means of sample analysis. In SEM, an electron gun fires an electron beam which is focussed through a series of lenses and apertures on the microscope. When these beams hit the sample, they interact with atoms on its surface, emitting secondary electrons, backscattered electrons, and x-rays. The microscope has built-in detectors that pick up these signals, using them to create high-resolution images and provide information on the composition of the specimen. The SEM operates under vacuum conditions, which prevents atoms or mo

Sales might even go down during this period. However, the pandemic does bring an opportunity to businesses that need change to their workplace. The placing of social distancing and strict laws due to the pandemic gives businesses the time to plan any renovations to their office. Whether it be changing the floorplan or changing the ventilation system, the lack of people within buildings is the perfect time to make some changes. It won’t disrupt the usual workflow, and you can also avoid any workplace hazards that can put your employees at risk. Admittedly though, it can be difficult to plan any changes for the business.

Over the years, the kitchen is one room in the house that has not seen a lot of changes. Sure, we may get a few new innovative products like electrical stoves, but everything almost remains the same. When it comes to renovations , the kitchen is often the second or third priority. But of course, the priority depends on which rooms need changing, but the kitchen often sees fixes instead of actual changes. The only time the kitchen’s appearance is changed is when a homeowner wishes to change not only the appearance but the feel of the kitchen. One can say that this is the beauty of kitchens. They often do not need changing, and simply need a bit of cleaning and touch-up. In the past decade, however, we have seen a few interesting trends come and go.
