With recent requirements for reducing greenhouse gas emissions of autonomous ships, an emerging body of research is focused on assessing the path-following performance of maritime autonomous surface ships (MASS) at low speeds under adverse weather conditions. To combat the poor accuracy of traditional methods, in a new study, researchers investigated the path-following performance of MASS using a free-running computational fluid dynamics model. Their findings can help ensure safer autonomous navigation with reduced propulsion power.

Perovskite nanosheets show distinctive characteristics with significant applications in science and technology. In a recent study, researchers achieved enhanced signal amplification in CsPbBr3 perovskite nanosheets with a unique waveguide pattern, which enhanced both gain and thermal stability. These advancements carry wide-ranging implications for laser, sensor, and solar cell applications, and can potentially influence areas like environmental monitoring, industrial processes, and healthcare.

Scientific researchers draw inspiration from nature's brilliance as they seek to develop transformative solutions to unresolved challenges.

Coal is an abundant resource in the United States that has, unfortunately, contributed to climate change through its use as a fossil fuel. As the country transitions to other means of energy production, it will be important to consider and reevaluate coal's economic role. Coal may actually play a vital role in next-generation electronic devices.

Researchers have fabricated a new high-performance shortwave infrared (SWIR) image sensor based on non-toxic colloidal quantum dots. They report on a new method for synthesizing functional high-quality non-toxic colloidal quantum dots integrable with complementary metal-oxide-semiconductor (CMOS) technology.

If you have a deep-seated, nagging worry over dropping your phone in molten lava, you're in luck. Materials scientists have developed a method for rapidly discovering a new class of materials with heat and electronic tolerances so rugged that they that could enable devices to function at several thousands of degrees Fahrenheit.

Chemists found a way to use electricity to boost a type of chemical reaction often used in synthesizing new candidates for pharmaceutical drugs. The research is an advance in the field of electrochemistry and shows a path forward to designing and controlling reactions -- and making them more sustainable.

Scientists develop a new, high-resolution technique for finding potential therapeutic targets on proteins in living cells. The findings could lead to more targeted therapeutics for nearly any human disease.

Imagine blasting off on a multiyear voyage to Mars, fueled by a diet of bland, prepackaged meals. As space agencies plan for longer missions, they're grappling with the challenge of how to best feed people. Now, researchers have designed the optimal 'space meal': a tasty vegetarian salad. They chose fresh ingredients that meet male astronauts' specialized nutritional needs and can be grown in space.

Aptamers, nucleic acids capable of selectively binding to viruses, proteins, ions, small molecules, and various other targets, are garnering attention in drug development as potential antibody substitutes for their thermal and chemical stability as well as ability to inhibit specific enzymes or target proteins through three-dimensional binding. They also hold promise for swift diagnoses of colon cancer and other challenging diseases by targeting elusive biomarkers. Despite their utility, these aptamers are susceptible to easy degradation by multiple enzymes, presenting a significant challenge.

While fog presents a major hazard to transportation safety, meteorologists have yet to figure out how to forecast it with the precision they have achieved for precipitation, wind and other stormy events. This is because the physical processes resulting in fog formation are extremely complex, Now researchers report their findings from an intensive study centered on a northern Utah basin and conceived to investigate the life cycle of cold fog in mountain valleys.

A research team has achieved a significant breakthrough in the field of organic semiconductors. Their successful synthesis and characterization of a novel molecule called 'BNBN anthracene' has opened up new possibilities for the development of advanced electronic devices.

Researchers have discovered that molecules experience non-reciprocal interactions without external forces. Fundamental forces such as gravity and electromagnetism are reciprocal, where two objects are attracted to each other or are repelled by each other. In our everyday experience, however, interactions don t seem to follow this reciprocal law.

A research team has unveiled a remarkable breakthrough in cancer treatment.

Researchers have developed a high-speed, high-sensitivity terahertz-wave detector operating at room temperature, paving the way for advancements in the development of next generation 6G/7G technology.

An international research group has engineered a novel high-strength flexible device by combining piezoelectric composites with unidirectional carbon fiber. The new device transforms kinetic energy from the human motion into electricity, providing an efficient and reliable means for high-strength and self-powered sensors.
