“Unlike people being able to put on a coat when it is cold or a swimsuit when it is warm, a battery wears the same ‘clothes’ everywhere with conventional thermal management technology,” Marconnet said. Ruan said the Purdue-invented thermal regulators improve upon this technology by changing the thickness of the material inside the regulators, which helps batteries continually adjust to different climates and seasons. It leads to poor performance like shorter driving ranges for electric vehicles and less cellphone usage time.”Ĭonventional thermal switches, analogous to electrical switches that moderate current flow, tune a battery’s heat dissipation pathways only by changing the conduction between on and off states. On the other hand, if the temperatures are too low, batteries suffer internal damage. This unstable reaction progression is called ‘thermal runaway’ and can even lead to fires and explosions. As they heat up, chemical reactions occur that cause them to heat up even faster. Marconnet said, “Batteries perform poorly if they are too hot. Similarly, batteries and electronic devices have a narrow temperature range to function appropriately as well, and are even more ‘picky’ than humans.” “We all know humans have a narrow range of temperature to live comfortably, and that is why we wear shirts in the summer to keep cool and coats in the winter to keep warm. “As batteries and electronic devices get more powerful, managing heat becomes a more crucial issue,” Ruan said. Marconnet is an associate professor in the School of Mechanical Engineering and a Perry Academic Excellence Scholar she also has a courtesy appointment in the School of Materials Engineering. Ruan is a professor in the School of Mechanical Engineering. The devices can dissipate heat, insulate against cold and function across a wide range of temperatures. AmScope 7X-45X Zoom Stereo Trinocular 3D Boom Microscope+LED Fiber Optic LightĪmScope 7X-45X Zoom Stereo Trinocular 3D Boom Microscope+LED Fiber Optic Light.Xiulin Ruan and Amy Marconnet have invented patent-pending, solid-state, continuously tunable thermal devices based on compressible graphene foam composites. 7X-45X large zoom magnification power with crisp sharp images.
2-1/2" (65mm) SUPER widefield of view and 4" (100mm) working distance.ģD boom stand allowing to point microscope head in any direction desired. Powerful 30W LED fiber-optic illumination. Auto-shut-off for electricity safety and color filter slot ready. This stereo industrial inspection microscopy system includes a trinocular 7-45X zoom microscope head, a double-arm boom and a 30 Watt LED fiber-optic illuminator. It is a perfect inspection viewing system offering sharp crystal clear images. The double-arm boom stand allows you to turn the microscope head around three different axes (x, y and z) that is, you can point the microscope head in any directions you wish. With the addition of the trinocular photo port, you can use a camera to view live images on a large or small-format monitor, as well as record the inspection process. The illuminator comes with one 22-long metal-sheathed fiber-optic cable, and provides bright and cool lighting. The fiber optic cable is flexible and can be bent into various positions. This inspection microscopy system is great for both industrial and biological applications. It is an ideal instrument for research labs, gemologists, and anyone in semiconductor and electronic industries.Ī turnkey package of inspection microscope with Fiber Optic Light.
