Kyocera and Tohoku University have developed a technique that uses localized laser annealing to crystallize magneto-optical garnet directly onto silicon photonic circuits. The method avoided thermal damage and achieved 13.6 dB of optical isolation, but resolving a 20.4 dB insertion loss remains a challenge for practical deployment.
According to the research team's theoretical model, an optimally curved amorphous silicon solar cell, evaluated based on device footprint, reached a maximum efficiency of 59.7% at a depth of 2 meters. Using calculations based on the optical properties of South Pacific water, the optimized curved solar cell's daily cumulative power output was 9.4-15.9% higher than that of a flat-panel design. However, practical implementation hinges on factors such as rapid light attenuation depending on water quality and depth, as well as resistance to corrosion, high water pressure, and biofouling.
An analysis of over 500 million rows of real-world EV operating data reveals that variation in cell degradation shortens battery life and leaves up to 27% of potential energy unused when packs are retired.
U.S.-based Muon Space achieved the first-ever in-orbit ignition of a solid-zinc Hall-effect thruster aboard its dedicated demonstration satellite, SERT-III. By completely eliminating high-pressure gas tanks in favor of a cheap, non-toxic solid metal propellant stable at room temperature, the company aims to dramatically streamline small-satellite manufacturing costs and launch-site operations.
A research team including the University of Hong Kong has developed a memristor circuit that combines an algorithm correcting for device manufacturing defects during the learning stage with a multilayer architecture, maintaining high associative memory capacity even under a 50% device defect rate. The study examines the scope and challenges of a design that demonstrated super-linear scaling on a physical chip.
Sandia National Laboratories has developed an electro-thermo-chemical memory using vanadium oxide, demonstrating both synaptic memory and neuron-like behavior in a single device. This article examines the physics behind the lab validation and the challenges remaining before practical use.
IonQ's paper details a roughly 20,000-qubit design to crack Bitcoin's signature math. But 26 days is one attempt, success is not guaranteed, and exposed public keys shape the real risk.
Google DeepMind has published predicted effects for roughly 9 billion single-letter DNA changes. Based on a rare-disease cell experiment and a population analysis, we look at where the Atlas can help narrow experimental candidates and what still has to be confirmed for causation and diagnosis.
JAIST's new additive, FPTI, helped a test cell retain 95.6% of its capacity after 1,000 charge-discharge cycles. In tests balancing compatibility with the cathode, the anode was pretreated separately, leaving long-term full-battery performance and manufacturing steps still to be verified.
Fujitsu unveiled a single-module quantum prototype that integrates tin-vacancy (SnV) centers into a photonic circuit. This article separates the 2027 optical-connection goal from the 2035 fiscal-year target to clarify where the technology stands and what performance data remain undisclosed.
