Thermal management emerges as a grand challenge of next-generation electronics. Efforts to develop compact, solid-state cooling devices have led to the exploration of the electrocaloric effect of ferroelectric polymers. Despite recent advances, the applications of electrocaloric polymers on electronics operating at elevated temperatures remain essentially unexplored. Here, we report that the ferroelectric polymer composite composed of highly-polarized barium strontium titanate nanofibers and electron-accepting [6,6] phenyl-C61-butyric acid methyl ester retains fast electrocaloric responses and stable cyclability at elevated temperatures.

Radiative cooling assisted self-sustaining and highly efficient moisture energy harvesting - Open Access
Harvesting electricity from ubiquitous water vapor represents a promising route to alleviate the energy crisis. However, existing studies rarely comprehensively consider the impact of natural environmental fluctuations on electrical output. Here, we demonstrate a bilayer polymer enabling self-sustaining and highly efficient moisture-electric generation from the hydrological cycle by establishing a stable internal directed water/ion flow through thermal exchange with the ambient environment.

A solar-driven atmospheric water extractor for off-grid freshwater generation and irrigation - Open Access
Solar-driven atmospheric water extraction (SAWE) is a sustainable technology for decentralized freshwater supply. However, most SAWE systems produce water intermittently due to the cyclic nature, with adoption hindered by complex design requirements or periodic manual operations. Herein, a fully passive SAWE system that can continuously produce freshwater under sunlight is presented. By optimizing the three-dimensional architecture to facilitate spontaneous mass transport and efficient energy utilization, this system can consistently produce 0.65 L m−2 h−1 of freshwater under 1-sun illumination at 90% relative humidity (RH) and functions in arid environments with an RH as low as 40%.

Clustering and routing protocols play a pivotal role in reducing energy consumption and extending the lifespan of wireless sensor networks. However, optimizing energy efficiency to maximize network longevity remains a primary challenge for these protocols. This paper introduces QPSOFL, a clustering and routing protocol that integrates quantum particle swarm optimization and a fuzzy logic system to enhance energy efficiency and prolong network lifespan. QPSOFL employs an enhanced quantum particle swarm optimization algorithm to select optimal cluster heads, utilizing Sobol sequences for population diversification during initialization. Read more…

Cobalt (II) Oxide (Co3O4)—reduced Graphene Oxide (rGO) and Platinum (Pt) based nanoparticles are coated over carbon cloth to increase the catalytic activity at the anode and cathode. Read more…
🌍 Climate related researches
Amidst a global wave of corporate pledges to decarbonize or reach net-zero emissions, a system for verifying actual greenhouse gas reductions has never been more important. Context Labs, founded by former MIT Sloan Fellow and serial entrepreneur Dan Harple SM ’13, is rising to meet that challenge with an analytics platform that brings more transparency to emissions data.

Days on Earth are growing slightly longer, and that change is accelerating. The reason is connected to the same mechanisms that also have caused the planet’s axis to meander by about 30 feet (10 meters) in the past 120 years. The findings come from two recent NASA-funded studies focused on how the climate-related redistribution of ice and water has affected Earth’s rotation. Read more…
Climate impacts of critical mineral supply chain bottlenecks for electric vehicle deployment - Open Access
New tailpipe emissions standards aim to increase electric vehicle (EV) sales in the United States. Here, we analyze the associated critical mineral supply chain constraints and enumerate the climate consequences of these constraints. Our work yields five findings. First, the proposed standard necessitates replacing at least 10.21 million new internal combustion engine vehicles with EVs between 2027 and 2032. Read more…
Gigantic wildfires in Canada, the Amazon and Greece have been amplified by global warming - Open Access
Greece, Mayotte, Algeria, the United States: Once again this summer, wildfires have been raging around the globe. But it's the previous fire season that a report published on Wednesday, August 14, looks back on in detail. It recalls the extent to which the extreme events observed in Canada, the Amazon and Greece in particular have generated significant CO2 emissions, thereby contributing to global warming. It also underlines that, as part of a downward spiral, these gigantic wildfires have themselves been made more likely by climate disruption. Read more…

RF Energy Harvesting. Explanation
RF energy harvesting is a process of capturing and converting radio frequency (RF) energy from the environment into usable electrical power. This technology is particularly useful for powering small, low-power devices such as sensors or remote electronic devices, reducing the need for traditional batteries. Here’s how it works:
Thermoelectric Energy Harvesting for Autonomous Systems by Dipl.-Ing. Harald Dillersberger
Abstract: "Latest wearables and IoT sensors use intelligent nano-power circuits and devices that harvest energy from environmental sources such as light or heat. Historically, there has been a gap between the energy demands of these circuits and the energy available from harvesting sources. Presently, we are approaching the cross-point where available harvested energy can exceed the energy consumption, making energy-autonomous systems possible. One significant problem is that energy harvesters such as thermoelectric generators typically produce a very low voltage. The available harvested energy is thus unusable without a power management integrated circuit to provide high efficiency voltage conversion at very low source voltages. This presentation includes fundamental research on existing solutions, the scientific value of a new boost converter topology and a summary of the results and shows first applications."
