An inkjet printer works by propelling tiny droplets of ink from cartridges onto paper to create an image or text. The printer’s software breaks down the image into pixels, mapping these on the paper. There are two main types of inkjet printers: thermal (used by brands like HP and Canon) and piezoelectric (used by Epson). In thermal inkjet printers, heat creates a bubble in the ink cartridge that propels a droplet of ink out of the nozzle. Piezoelectric printers, however, use a piezoelectric material which changes shape when an electric current is applied, forcing the ink out. Printing quality depends on the printer's resolution (measured in DPI - dots per inch) and the type of ink and paper used. Inkjet printers are popular for their ability to produce high-quality color images and for their affordability.

Titanium is a chemical element with the symbol Ti and atomic number 22. It is a lustrous transition metal with a silver color, low density, and high strength. Titanium is resistant to corrosion in sea water, aqua regia, and chlorine. Found in numerous minerals, primarily rutile and ilmenite, which are widely distributed in the Earth's crust and lithosphere, titanium is used in various applications due to its durability and lightweight properties. It's essential in aerospace designs for aircraft and spacecraft because of its high strength-to-weight ratio and resistance to high temperatures. In the medical field, it is used for surgical implants due to its biocompatibility. Additionally, because it does not react with the human body, it's also used in jewelry. Its resistance to erosion and bio-corrosion also makes it useful in marine and chemical processing industries.

To add a new skein of yarn while knitting, first, ensure both yarns are from the same dye lot and are the same type to maintain color and texture consistency. Begin by preparing the new skein: unwind a few yards, and secure it near your work without creating tension. As you approach the end of the current skein, gently join the new one. There are several techniques for joining; a simple method involves overlapping the ends for an inch or two and continuing to knit with the new skein. Another popular method is to tie a loose knot at the joining point, ensuring it won't unravel but will not be too tight. After adding the new skein, continue knitting as usual. Later, weave in the ends using a yarn needle to hide them neatly on the wrong side of your project. This ensures the addition is seamless and maintains the integrity of your knitting.
