MATERIALS:Master Bond EP30M3LV is a specially engineered, low exothermic epoxy system formulated to help avoid excess heat buildup and damage to thermally sensitive components during potting operations. It also contains a special additive to remove air bubbles. This compound cures at room temperatures or more rapidly at elevated temperatures, and can be cured in various cross section thicknesses. EP30M3LV has a volume resistivity of 2×1015 ohm cm at 25C. It has a convenient 2:1 mix ratio by weight and an advantageously low mixed viscosity of 2,000-3,000 cps. It has a service operating temperature range of -60 to 250F. EP30M3LV also has superior dimensional stability, a flexural strength of 14,000 psi and a tensile strength of >8,000 psi. Master Bond EP30M3LV is environmentally friendly, 100 percent reactive and contains no solvents or diluents. It is available for use in half-pint, pint, quart, gallon and 5 gal pail kits.
During a teardown of the iPad Air and Microsoft Surface Pro 3 at the Medical Design & Manufacturing Show in Schaumburg, Ill., an engineer showed this "inflammatory" video about the dangers of maliciously mishandling lithium-ion batteries.
Science fiction author Isaac Asimov may have the best rules for effective brainstorming and creativity. His never-before-published essay, "On Creativity," recently made it to the Web pages of MIT Technology Review.
Much has been made over the potentially dangerous flammability of lithium-ion batteries after major companies like Boeing, Sony, and Tesla have grappled with well-publicized battery fires. Researchers at Stanford University may have come up with a solution to this problem with a smart sensor for lithium-ion batteries that provides a warning if the battery is about to overheat or catch fire.
In this new Design News feature, "How it Works," we’re starting off by examining the inner workings of the electronic cigarette. While e-cigarettes seemed like a gimmick just two or three years ago, they’re catching fire -- so to speak. Sales topped $1 billion last year and are set to hit $10 billion by 2017. Cigarette companies are fighting back by buying up e-cigarette manufacturers.
