Innovative PLA or PCL‐Based Ocular Implants Obtained From Tape Casting or Electrospinning for Sustained‐Release Dexamethasone

open access: yesJournal of Applied Polymer Science, EarlyView.
PLA and PCL ocular implants prepared by tape casting and electrospinning provide sustained dexamethasone release with distinct release profiles governed by polymer type and processing method. The relationship between polymer structure, degradation behavior, and drug release demonstrates the potential of these fabrication techniques for controlled ...

Ceramic ecology in an Islamic capital: changes in the production and consumption of pottery in Palermo

open access: yesEarly Medieval Europe, EarlyView.
Palermo became the new capital of Sicily after the Aghlabid conquest in 831. The transformation of the city into a capital took many forms, including the production and consumption of pottery. The perspective from ceramic evidence shows that Palermo underwent faster and deeper processes of Islamization than other urban and rural contexts across the ...
