Water-based Air Conditioner cools without harmful Chemicals

A team of researchers from the National University of Singapore (NUS) has pioneered a new water-based air-conditioning system that cools air to as low as 18 degrees Celsius without the use of energy-intensive compressors and environmentally harmful chemical refrigerants. This game-changing technology could potentially replace the century-old air-cooling principle that is still being used in … Continue reading “Water-based Air Conditioner cools without harmful Chemicals”

Turning heat into electricity using “topological” materials

With advancements in thermoelectric technology, in future, you could run your air conditioner using sun’s heat instead of conventional electricity. Thermoelectric devices are made from materials that can convert a temperature difference into electricity, without requiring any moving parts — a quality that makes thermoelectrics a potentially appealing source of electricity. The phenomenon is reversible: … Continue reading “Turning heat into electricity using “topological” materials”

Drones let researchers monitor changes in volcanoes, plan virtual field trip

Penn State geosciences researchers are investigating an active volcano that could pose a hazard to millions of people in Nicaragua. Masaya volcano is located in an active volcanic and seismic zone and is nearby Managua, Nicaragua’s capital. The researchers are using many methods, including drones, to study how the volcano and surrounding earth are changing … Continue reading “Drones let researchers monitor changes in volcanoes, plan virtual field trip”

Scientists use underwater robot created by Northeastern researcher to spy on zooplankton at night

Zooplankton are the foundation of the marine food chain. These tiny organisms provide food and energy to fish, sea birds, and other marine mammals—including the bowhead whale, which feeds exclusively on zooplankton. What do zooplankton eat? They feed on phytoplankton, which rely on sunlight. But in the Arctic Ocean during winter months, there is little to … Continue reading “Scientists use underwater robot created by Northeastern researcher to spy on zooplankton at night”

3-D printing remakes the strain gauge

Rahul Panat and a team of researchers from CMU, WSU, and UT-El Paso have developed a new 3-D printing technique for manufacturing strain gauges that breaks the Poisson Ratio by 40%. Have you ever weighed your car at a weighing station on the highway? Have you ever thought about how the deflections in an airplane … Continue reading “3-D printing remakes the strain gauge”
