Producing Safe Drinking Water with a Novel Nanoparticle Biofoam
Around the world, millions of people lack access to improved sources of drinking water. Pesticides, bacteria, organic matter, and other pollutants can make accessible water unsafe for human consumption. Finding a cost-effective and easy method to purify water is therefore a major global initiative. One possible solution is a nanoparticle biofoam, which may provide an efficient method for generating safe drinking water.
Particle Tracing in a Component of a Quadrupole Mass Spectrometer
Quadrupole mass filters, the key component of quadrupole mass spectrometers, filter ions by their charge-to-mass ratio, only allowing ions with a certain ratio to pass through the device. As such, a high transmission probability for a specific ion through the filter is desirable. However, fringe fields in the mass filter can affect this probability. By using multiphysics simulation, we can take a closer look at quadrupole mass filters and investigate the effect of fringe fields on these devices.
Do Bumblebees Use Their Hairs or Antennae for Electroreception?
While bumblebees are not a complete mystery, we still have a lot more to learn about these helpful insects. A topic with a lot of buzz surrounding it is how they find food. Using electroreception, an ability most often found in aquatic animals, is one possibility. But how do bumblebees use electroreception? To find answers, a research team at the University of Bristol combined the power of physical experiments and simulation.
Enhance Your Visualization Plots with 6 New Color Tables
You’ve generated your simulation results and you want to communicate your findings with other people. To do so clearly and effectively, you will need to create easy-to-understand, eye-catching visualizations. Therefore, as of COMSOL Multiphysics® software version 5.2a, you now have six new color tables to further enhance your postprocessing. Let’s learn about the inspiration behind these color tables and take a look at a few specific use cases.
Designing Reliable and Efficient CDRA Systems with Simulation
Manned vessels traveling through space require highly efficient and reliable life support systems, such as carbon dioxide removal assemblies (CDRAs). Poorly designed systems can shorten missions and cause potential danger. Simulating CDRA systems, however, can be quite time-consuming and difficult due to their complex nature. To address such challenges, a team at NASA’s Marshall Space Flight Center developed a 1D model in the COMSOL Multiphysics® software to efficiently analyze the 4-bed molecular sieve (4BMS) of a CDRA system.
AltaSim Uses Simulation to Improve Bolometer Sensitivity
Bolometers have the ability to detect and measure the power of incident electromagnetic radiation. This allows them to be used in a range of technologies, from night vision cameras to far-reaching astronomy projects. Designing bolometers often requires devoting a lot of time and energy to the development phase, as these devices must be optimized for sensitivity and customized for their specific applications. To efficiently design bolometers with increased sensitivity, AltaSim Technologies utilized the simulation capabilities of COMSOL Multiphysics.
Reducing Motorcycle Engine Noise with Acoustics Modeling
When designing motorcycles, noise reduction is a primary area of concern. Loud, poorly designed motorcycles may not meet noise regulations or satisfy customers. As such, there is a need to reduce motorcycle noise by identifying and eliminating its sources. To do so, researchers at Mahindra Two Wheelers, Ltd. turned to acoustics simulation.
ETREMA Analyzes Magnetostrictive Materials with Simulation
The magnetostrictive effect causes magnetic materials to change their shape when a magnetic field is applied. Materials that exhibit such behavior are used in a range of devices, from loudspeakers to actuators. In order to analyze one type of device, a magnetostrictive transducer, researchers from ETREMA Products, Inc. performed single-physics and multiphysics simulation studies in COMSOL Multiphysics. See how the flexible nature of the software enabled the team to study various aspects of the device and optimize its overall design.
