Chewable Soft Gelatin Capsules: Design and Formulation Strategies for a Patient‐Preferred Dosage Alternative

open access: yesMacromolecular Materials and Engineering, EarlyView.
Chewable softgels are a patient‐preferred alternative to conventional oral forms, offering pleasant taste, fast onset, and suitability for children or patients with swallowing difficulties. However, they present relevant challenges in their formulation: the shell must balance chewability, machinability, and stability, while the fill must mask the ...

Beeswax-modified biopolymer aerogel: A sustainable approach to hydrophobic oil absorbing materials

open access: yeseXPRESS Polymer Letters
This study presents for the first time a sustainable approach to hydrophobic modification of nanocellulose/chitosan bioaerogels using beeswax emulsion. The incorporation of beeswax into the aerogel matrix resulted in increasing the density from 35.1 to ...

Cooperative human signals to honeyguides form local dialects

open access: yesPeople and Nature, EarlyView.
Abstract Human language enables the exchange of complex information and precise instructions for collaborative planning and action. It rapidly evolves through social learning, generating diverse cultural communication signals used not only with other humans, but also with domesticated animals bred or trained to respond.

Polarization vision and the physiological basis for trichromatic vision in Philaenus spumarius: Understanding host‐seeking behaviour in insect vectors for Xylella fastidiosa control

open access: yesAnnals of Applied Biology, EarlyView.
We investigated the role of vision in host‐seeking behaviour by Philaenus spumarius, the main European vector of Xylella fastidiosa, through an integrated anatomical, optical, physiological, and behavioural study. Our data highlight that the spittlebug uses visual cues, including polarized light, which may aid in detecting the polarized reflections ...

Enhancing solar water heater efficiency: A study on heat transfer with phase change material

open access: yesResults in Engineering
Solar energy, known for its abundance, affordability, and renewability, plays a crucial role in domestic applications. However, its intermittent nature demands efficient storage systems. This study proposes using beeswax, a low-melting-point phase change
