 | Precision dispensing for micro-electronics
The spread of miniaturization in automation has led to an ever-increasing demand for optimum dispensing of the tiniest volumes. Whether in electronics or micro-mechanical engineering, solder pastes, adhesives, lubricants, and 3D-printing filament must be applied or extruded precisely where needed, in exactly the right dosage and without spillage or dripping. Compact, high-torque DC motors deliver the precision and small size needed for such a challenge.

 | Odorless thermal insulation material for automotive
Interface Performance Materials introduces TI650 and TI1K innovative thermal insulation materials for automotive and heavy-duty vehicle heat shield applications. TI650 and TI1K are the first odorless and smokeless materials specifically formulated for three-layer heat shields in the automotive, medium-, and heavy-duty vehicle applications. These non-toxic materials withstand temps up to 1,000 C (1,832 F), are malleable, and are resistant to cracking when molded into a layered heat shield. Their low-density makeup makes them the ideal substrates for lightweight initiatives by OEMs and fabricators. A highly inorganic material, TI1K is also unique in its ability to meet the ASTM E136 flammability test standard with no detectable smoke.

 | High-torque rotary voice coil actuators
H2W Technologies has developed several high-torque rotary voice coil actuators, otherwise known as a limited angle torque motors (LATs). The model TWR-015-346-2RC was designed to allow for a low moving mass (68 grams per coil) and inertia, as well as dual independent coils to allow for two independent motion profiles or couple the coils together to double the torque output. This rotary voice coil actuator can generate a continuous torque of 185 in.-oz (1.29 Nm) and a peak torque of 555 in.-oz (3.88 Nm) at a duty cycle of 10% (i.e., 1 sec on and 9 sec off) in each coil on a 4-in. (102-mm) rotation arm. By coupling the coils, the continuous torque doubles. Applications include driving a gimbal axis in scanning applications and providing stabilizing torques for image stabilization.

Is DNA the future of data storage? Fascinating!
In the event of a nuclear fallout, every piece of digital and written information could be lost. Luckily, there is a way that all of human history could be recorded and safely stored beyond the civilization's end, and the key ingredient is inside all of us: our DNA. Science writer/editor Leo Bear-McGuinness explains. Wait until you see how much DNA space it takes to store the entire contents of the internet!
