Minus K Congratulates to the following winners of Minus K's 2024/2025 Educational Giveaway
Celebrating its’ tenth year of their U.S. Educational Giveaway, Minus K Technology has to-date granted over $100,000 of its superior performing patented Negative-Stiffness low-frequency passive mechanical vibration isolators to colleges and universities in the USA. This year Minus K congratulates the following winners for the 2024/2025 giveaway: University of North Texas - Physics Department The vibration isolator will be used to stabilize their AFM to achieve high resolution images of grain sizes in thin films. They will modify these films through different thermal processes. Rose-Hulman Institute of Technology - Physics and Optical Engineering Department The vibration isolator will be used for experiments in ultra-sensitive optical measurements and characterization of magneto-optic nanoparticles for cancer hyperthermia therapy. Wellesley College – Chemistry Department The isolator will for research studies of pathological changes to excitable cells using fluorescent reporters. They will use microinjection and electrophysiology on intact worms in vivo and culture cells using their Nikon Ti-U microscope which currently has too much vibration movement. Cornell University – Applied and Engineering Physics Department The isolator will used fabricating novel two-dimensional (2D) material heterostructures by combining atomically thin 2D materials, such as graphene, hBN, transition metal dichalcogenides, to explore new electronic and quantum phenomena inside an MBraun glovebox under an inert argon atmosphere. Rutgers University – Physics Department The isolator will be for a scalable atomic gravimeter to measure the absolute gravity, the vertical gravity gradient, and the third-order vertical derivative by dropping three spatially separated cold-atom cloud and forming atom interferometry, to a retroreflector under a vacuum chamber. Sam Houston State University – Biological Sciences The isolator will assist in fluorescent and phase contrast imaging using an ECHO Revolve upright/inverted microscope, allowing publication-quality fluorescence, phase, and darkfield imaging to graduate and undergraduates in research or doing live-cell video. “Giving back to academia always gives us great feeling.”, says Minus K’s President Steve Varma, “When talking to students at our booth at the different trade shows, there is always a great interest in getting isolation systems for their schools to help with their experiments. We are proud of being able to provide systems for ten years.” Minus K® Technology, Inc. was founded in 1993 to develop, manufacture and market state-of-the-art vibration isolation products based on the company’s patented negative-stiffness-mechanism technology. Minus K products are used in a broad spectrum of applications including nanotechnology, biological and neuro sciences, semiconductors, materials research, quantum research, zero-g simulation of spacecraft, and high-end audio. The company is an OEM supplier to leading manufactures of scanning probe microscopes, micro-hardness testers and other vibration-sensitive instruments and equipment. Minus K customers include private companies and more than 300 leading universities and government laboratories in 52 countries.

New CT-10 Ultra-Thin, Compact Low-Height, Low-Frequency Vibration Isolation Platform Adapts to Space Constraints
The new ultra-thin, low-height model CT-10 passive isolator – the more compact than the CT-2 to fit in much smaller spaces at just over 12 ½ inches square. The completely passive tabletop unit is 2.7 inches in height, yet delivers 1/2 Hz vertical natural frequency, and ~1-1/2 Hz horizontal natural frequencies – considerably more low-frequency vibration isolation performance compared to air tables and active systems. The CT-10 utilizes Minus K's breakthrough patented technology that led to a Laser Focus World 2019 Innovation Award. Negative-Stiffness isolators employ a unique and completely mechanical concept in low-frequency vibration isolation. They do not require electricity or compressed air. There are no motors, pumps or chambers, and no maintenance because there is nothing to wear out. They operate purely in a passive mechanical mode. The Negative-Stiffness CT-10 isolator achieves a high level of isolation in multiple directions. It has the flexibility of custom tailoring resonant frequencies vertically. The transmissibility of the CT-10 is substantially improved over air and active isolation systems. When adjusted to 1/2 Hz vertical natural frequency, the CT-10 Negative-Stiffness isolator achieves approximately 93 percent isolation efficiency at 2 Hz; 99 percent at 5 Hz; and 99.7 percent at 10 Hz. Negative-Stiffness vibration isolation systems have become a growing choice for Laser and Photonics applications. Not only are they a highly workable vibration solution, but they provide location flexibility and portability that other vibration isolation systems cannot. At about 2-1/2 inches in height, while isolating vibrations as low as 1 hertz, the new completely-passive Negative-Stiffness tabletop vibration isolation platform – developed by Minus K Technology – provides the industry’s thinnest low-height, low-frequency isolator for Microscopy (SPM, SEM, AFM, etc.), Micro-Hardness and Nano-Indenter Testing, Laser/Optical Systems, Biology/Neuroscience Systems, Spacecraft Ground Testing, Analytical Balances, Audio Reproduction, Vacuum and Cleanroom applications.
