Interfacial Passivation for Enhanced Moisture Stability of Perovskite Solar Cells: Ammonium or Sulfonium?

open access: yesAdvanced Materials Interfaces, EarlyView.
By directly comparing the impact of dual interfacial passivation by ammonium‐, sulfonium‐ and sulfoxonium‐based cations on the performance and stability of triple cation metal halide perovskite solar cells, it is found that it is the exact molecular structure of the cation, rather than the nature of the onium that influences the efficacy of passivation

Sol–Gel Thin Films for the Protection of Ancient Glass Artifacts: A Performance Comparison Between Inorganic and Hybrid Silica Compositions

open access: yesAdvanced Materials Interfaces, EarlyView.
This study explores the development of sol–gel coatings for archaeological glass conservation. By formulating silica‐based solutions with low acid concentrations and applying them via dip coating, protective films are prepared at room temperature. Analysis reveals that hybrid coatings with methyl and octyl groups provide superior protection against ...

Enhancing Environmental Stability and Transparency of Glass Coatings Using Silica Nanoparticles in the Sol‐Gel Process

open access: yesAdvanced Materials Interfaces, EarlyView.
This study presents a novel silica‐based sol‐gel coating enhance with silica nanoparticles to protect glass surfaces. By reducing formulation acidity and improving resistance to environmental alteration—especially with 50 nm particles and double‐dip application—the method creates a gentle yet effective protective barrier.

Supramolecular Nanoarchitectonics of PNIPAAM‐co‐MA and Imogolite to Obtain Thermoresponsive Clay Nanotubes Through Complexation Mechanism

open access: yesAdvanced Materials Interfaces, EarlyView.
The selective adsorption of anionic poly(N‐isopropylacrylamide)‐co‐methacrylic (PNIPAAM‐co‐MA) onto the external surface of imogolite nanotubes is driven by electrostatic attractions. The copolymer coating affects the surface charge, aqueous diffusion and self‐assembling of imogolite.

Poka: A Necro‐Robot Beetle with a Measured Payload Ratio of 6847%

open access: yesAdvanced Robotics Research, EarlyView.
Here, Poka, a necro‐robot beetle with the ability to carry more than 68 times its own weight, is introduced, making it also a walking robot with the highest payload ratio measured to date. This paper is concerned with the design, manufacture and validation of ‘Poka', a novel millimetre‐scale necro‐robot aimed at bridging the performance gap between ...

Remote Control of Hand Actuators via Glove Sensors for Medical Care Applications

open access: yesAdvanced Robotics Research, EarlyView.
This study presents a novel textile‐based sensory glove–actuator system for remote medical care, explored through finite element simulations. By integrating capacitive sensors, pneumatic actuators, and machine learning, the system models real‐time hand movement control.

Cold Plasma Generates a Localized Inflammatory Response and Promotes Muscle Repair

open access: yesAdvanced Therapeutics, EarlyView.
The immediate tissue response to plasma is a pro‐inflammatory response which is characterized by collagen clumping, innate immune cell infiltration, enhanced metabolic processes, and decreased apoptosis. The long‐term tissue response (4‐ and 14‐days) to plasma treatment is characterized by a decreased inflammatory response, decreased adipogenesis, and ...

Emerging Therapeutic Strategies for Hearing Loss

open access: yesAdvanced Therapeutics, EarlyView.
Challenges still exist in treating hearing loss in cases of severe damage to hair cells or spiral ganglion neurons. Here, a schematic diagram of cochlear sensory hair cells and auditory nerves is presented. It is found that in normal Corti organs, hair cells have upright stereocilia at the top and auditory neurons at the base. Ototoxic drugs, noise, or
