Solar-powered aircraft could stay aloft for weeks or months, but making that possible depends heavily on the batteries carrying them through each night. A new study identifies a battery target that could make persistent flight practical across much wider areas.
A machine learning model built on eight material descriptors predicted the specific capacity of nitrogen-doped porous carbon cathodes for zinc-ion hybrid supercapacitors, and an optimized device synthesized to test it delivered 160.3 mAh g–1 at 0.1 A g–1, close to the predicted 154.4 mAh g…
A simulation study finds that pairing serrated textures at the front interface and back electrode of all-perovskite tandem solar cells cuts reflection-induced photocurrent losses by 18.34 percent and is expected to raise efficiency to about 31.13 percent. Subject of Research: Optical simulation…
Powering the next generation of wearable devices, skin-like electronics, and smart clothing and displays will require batteries that don’t just flex but also stretch and compress. Most past efforts to make stretchable batteries use metal-based conventional chemistries like lithium ion…
ADI MAX17055: ModelGauge m5 Fuel Gauge ModelGauge m5 EZ algorithm for state-of-charge and remaining capacity. Automatic compensation for cell aging, temperature and discharge rate. Reports SOC in percent and remaining capacity in mAh. Low 7 uA operating current for long shelf and standby life.
The converter is built on a two-phase interleaved boost topology with a relay-assisted reconfiguration stage. This arrangement facilitates flexible source selection, battery charging and discharging, and regenerative braking operation, allowing energy recovered during braking to be routed productively back into…
A computational study designed three P3CPenT-based donor–acceptor molecules whose calculated energy gaps, visible-light absorption and theoretical efficiency descriptors outperform the parent compound as candidate hole transport materials for perovskite solar cells. Subject of Research: Computational design of P3CPenT-based hole…
Oct 29, 2026 — 8:43 PM ET Multiple reports from owners spanning from the Pixel Watch 2 up to the current generation all shared similar tales: battery life diving even as the watches sat idle. Disabling the Always-on Display didn’t seem to make much of…
Crystals in the lab aren’t gemstones. They’re materials built from atoms arranged in precise, repeating patterns. That atomic order lets crystals absorb light, move charge and convert energy, enabling technologies from LEDs and solar cells to the sensors in everyday…
Atomic-scale imaging reveals how vacancy chemistry and lattice strain shape the birth and behavior of copper nanoparticles inside perovskite oxides. In a recent article in Nature Communications, researchers describe the nanoscale mechanisms of metal nanoparticle exsolution from perovskite oxides by…
