New heat-tolerant, high-capacity capacitor created with solid electrolytes borrowed from all-solid-state batteries

Posted by in categories: chemistry, climatology, sustainability, wearables

Capacitors are energy storage devices—consisting of two electrodes and an electrolyte—that are capable of rapid charging and discharging because of charge adsorption and desorption properties at the electrode-electrolyte interface. Because capacitors’ energy storage does not involve chemical reactions, their storage capacity is lower than that of lithium-ion batteries, but they are useful for power leveling for renewable energy that requires repeated charging at high currents, regenerative braking energy for trains and electric or hybrid cars, as well as instantaneous voltage drop compensation devices that prevent equipment failure due to lightning strikes. They are also expected to be used to store energy for wearable devices in the near future.

Most capacitors use a liquid electrolyte with a low boiling point, which can only be used at temperatures below 80℃. Ceramic capacitors that use solid inorganic materials as a dielectric can be used at temperatures above 80℃, but their is much lower than liquid electrolyte capacitors, which limits their use to electronic circuits.

To increase the energy storage of capacitors, it is necessary to have a large contact area at the interface between the electrode and the electrolyte. Making a large contact area is difficult using ; so, the creation of a capacitor with high storage capacity that can also operate at high temperatures has been desired for a long time.

NUS researchers invent self-charging, ultra-thin device that generates electricity from air moisture

Posted by in categories: engineering, health, sustainability, wearables

This new invention is highly scalable since its raw materials are commercially available and easy to access.

A team of researchers from the National University of Singapore’s (NUS) College of Design and Engineering (CDE) has developed a self-charging electricity generation (MEG) device that generates electricity from air moisture, according to a press release by the institution.


Imagine being able to generate electricity by harnessing moisture in the air around you with just everyday items like sea salt and a piece of fabric, or even powering everyday electronics with a non-toxic battery that is as thin as paper. A team of researchers from the National University of Singapore’s (NUS) College of Design and Engineering (CDE) has developed a new moisture-driven electricity generation (MEG) device made of a thin layer of fabric — about 0.3 millimetres (mm) in thickness — sea salt, carbon ink, and a special water-absorbing gel.

Open-source software enables researchers to visualize nanoscale structures in real time

Posted by in categories: computing, nanotechnology, sustainability, transportation

Computer chip designers, materials scientists, biologists and other scientists now have an unprecedented level of access to the world of nanoscale materials thanks to 3D visualization software that connects directly to an electron microscope, enabling researchers to see and manipulate 3D visualizations of nanomaterials in real time.

Developed by a University of Michigan-led team of engineers and software developers, the capabilities are included in a new beta version of tomviz, an open-source 3D data visualization tool that’s already used by tens of thousands of researchers. The new version reinvents the visualization process, making it possible to go from microscope samples to 3D visualizations in minutes instead of days.

How data and automation can help with sustainability

Posted by in categories: business, economics, robotics/AI, sustainability

Weighing cost vs. benefit

For small business owners, implementing sustainability initiatives may seem more like a pipe dream than a tangible goal, as the technology can be costly to implement. What’s more, businesses that are using technology to drive sustainability must employ talented workers who can tap into those resources and streamline operations for the greatest economic and environmental benefit.

However, as companies can leverage automation and data analytics to increase efficiency, adjust energy usage, reduce waste and otherwise help with sustainability, the cost of investing in automation is worth it. By giving company leaders the ability to see the big picture in terms of carbon footprint, data and automation can help optimize operations and improve a company’s bottom line.

The concept of MEG devices is built upon the ability of different materials to generate electricity from the interaction with moisture in the air. This area has been receiving growing interest due to its potential for a wide range of real-world applications, including self-powered devices such as wearable electronics like health monitors, electronic skin sensors, and information storage devices.

Is propane a solution for more sustainable air conditioning?

Posted by in categories: climatology, space, sustainability

Current severe heatwaves that will likely increase in severity and frequency in the future are driving a rise in the use of air conditioners, threatening the environment with their high energy consumption and refrigerants with high warming potential. A new study finds that switching to propane as a refrigerant could lessen the global temperature increase from space cooling.

We spend enormous amounts of energy on fighting off the heat in the summer, or throughout the whole year at lower latitudes—about one-tenth of the total worldwide electricity supply. If current temperature trends continue, the energy demands of space-coolers will more than triple by 2050. Apart from the rise in , space-coolers also threaten the in different ways: by using halogenated refrigerants with high potential.

Split-air conditioners (Split ACs) that use an indoor and an outdoor air unit connected by pipes are the most common appliances used for space-cooling. They mostly utilize HCFC-22 and HFC-410 as refrigerants, both of them characterized by a very high global warming potential score, up to 2,256—meaning that they trap up to 2,256 times more heat than over 100 years. Urged by the Kigali Amendment to the Montreal Protocol, many manufacturers are looking for alternative refrigerants with lower global warming potential scores, such as HFC-32. However, with a global warming potential score of 771, HFC-32 still poses a significant climate hazard.
