Many students, especially non-science majors, dread chemistry. The first lesson in an introductory chemistry course typically deals with how to interpret the periodic table of elements, but its complexity can be overwhelming to students with little or no previous exposure. Now, researchers reporting in ACS

When in space, astronauts typically eat dehydrated, nutrient-dense food, but when it comes to longer space missions, that can become a problem as they ll eventually lack nutrients from fresh vegetables. However, one chemical and biomolecular engineering professor will be researching ways astronauts can grow their own fresh vegetables more efficiently while they are on missions.
Ying Diao was recently awarded the NASA Early Career Faculty award for her proposal: Remote Autonomous Plant Sensing for Space Exploration Enabled by Wearable Printed Electronics.
Diao s goal for this research is to develop wearable sensors for plants so that their health and stress levels are detected autonomously, with no need for humans to do the testing. Then, a smart plant chamber will be developed that can identify the best conditions for a plant to grow in to reduce its stress. Diao also wants to develop another sensor that will continuously monitor a

The Korea Institute of Science and Technology (KIST) has announced that the research team led by Dr. Kim Kyoung-Whan at the Center for Spintronics has proposed a new principle about spin memory devices, which are next-generation memory devices. This breakthrough presents new applicability that is different from the existing paradigm.
Conventional memory devices are classified into volatile memories, such as RAM, that can read and write data quickly, and non-volatile memories, such as hard-disk, on which data are maintained even when the power is off. In recent years, related academic and industrial fields have been combining their advantages to accelerate the development of next-generation memory that is fast and capable of maintaining data even when the power is off.

Producing clean energy and reducing the power consumption of illumination and personal devices are key challenges to reduce the impact of modern civilization on the environment. As a result, the surging demand for solar cells and light-emitting devices is driving scientists to explore new semiconductor materials and improve their performances, while lowering the production costs.
Semiconductor nanocrystals (materials with sizes about 10 nanometers, which is approximately 10,000 times thinner than our hair) hold great promise for these applications: they are cheap to produce, can be easily integrated in these devices and possess exceptionally enhanced properties upon interaction with the light, as compared to their bulk

ORLANDO, Jan. 12, 2021 -Vehicles have evolved to become more efficient and sophisticated, but their fuel hasn t necessarily evolved along with them. The Department of Energy is determined to identify cleaner burning and renewable alternatives to gasoline, and through the work of two UCF researchers, the DOE is one step closer to that goal.
Research engineer Anthony C. Terracciano and Associate Professor Subith Vasu have developed a model that will help engine designers, fuel chemists and federal agencies determine whether certain biofuels should be implemented as an alternative fuel for vehicles.
The research was conducted as part of the DOE s Co-Optimization of Fuels and Engines initiative, better known as Co-Optima. Findings were recently published in Nature
