Pencil graphite is composed of graphite, clay, and resin and their proportions vary according to a grading scale, which considers hardness (H) and darkness (B). The hardness is determined by the amount of clay added to the pencil leads during production, the more the clay the harder the ...
my son and i have stopped using the regular controller and now solely rely on the mx ink stylus. it’s much easier to use and feels more natural compared to the traditional controller. i’m looking forward to using the mx mat when it...
3.2a. Electrodes for metal processing with large diameter, various jigs with different sizes and also leads for automatic pencil with a diameter as thin as 0.3 mm are fabricated by this forming process. In the molding process, the filler particles are statistically aligned perpendicular to the ...

(1999) prepared a new carbon electrode similar to pencil lead with crystalline graphite powder reinforced by amorphous carbon (GRC). This new graphite electrode simultaneously detects serotonin in presence of DA, AA, and nitrite ion with good peak separation. To achieve high level of sensitivity, ...
