Comprehensive analysis of nanocellulose as a promising component in the development of advanced flexible materials. Emphasizes potential applications in electronics, energy storage, and biomedicine, and investigates the challenges and future perspectives in the field.
Researchers have developed a low-cost and simple method for printing electronics using regular pens and a benchtop plotter. This technique allows for the use of virtually any solution-processable nanomaterial ink without the need for expensive equipment or ink optimization, making printed electronics more accessible.
Researchers report remarkable quantum composites based on polymers with fillers comprised of a van der Waals material that reveals multiple quantum condensate phases. The quantum composites revealed unusually high dielectric constant while remaining electrically insulating.
Researchers demonstrate a new way to create chiral nanostructures using a laser beam. By carefully controlling the direction of the laser beam's vibrations, the researchers created a variety of chiral structures made of platinum oxide in unique shapes, like twisted micropillars and spiral superstructures.
Hygromorphs are materials that can change their shape or size in response to changes in humidity or moisture. Synthetic hygromorphs, designed to have specific responses to changes in humidity, can be used in various applications, such as in sensors and actuators. A recent review generalizes a full design process for a 4D printed hygromorph which includes designing concepts, using additive manufacturing to produce designs, and measuring actuation.
Perovskite solar cells (PSCs) are complex devices made up of multiple materials that have many different factors affecting their properties, which makes it difficult to analyze them comprehensively. Machine Learning (ML) can efficiently handle these complexities and help scientists in the design of new PSCs. We outline the current state and future prospects of ML in perovskite solar cell research, including data sources, feature extraction, algorithms, model validation, interpretation, and challenges.
Inspired by living biological systems, which can sense, process information, and actuate in response to changing environmental conditions, researchers are exploring engineered living hydrogels. The convergence of engineering, biology, and materials science over the past 20 years is providing unprecedented opportunities to integrate living cells into these hydrogels. This integration yields engineered living hydrogels with the capabilities of self-replication, self-regulation, and environmental responsiveness.
The development of efficient cooling technology based on environmentally friendly and biobased materials is crucial to many day-to-day activities. A novel, highly efficient cellulose nanocrystal aerogel radiative cooler acts as a dual-function thermal insulator and daytime passive radiant cooler. These aerogel coolers can save on average more than 35% in cooling energy consumption and they are capable of achieving a nearly 9 degree C drop under direct sunlight, they even work effectively in hot, moist, and fickle extreme surroundings.
