Combining Selective Laser Sintering and Fused Deposition Modeling of Pharmaceutical Polymers: A Novel Approach to Prepare Intestine‐Targeted Tablets

open access: yesMacromolecular Materials and Engineering, EarlyView.
Selective laser sintering (SLS) and fused deposition modeling (FDM) are combined to prepare intestine‐targeted tablets with controlled drug release. The SLS‐printed core contains a model drug. The FDM‐printed coating shell modifies drug release and increases tablet mechanical resistance.

A DEM Model for Assessing the Mechanical Effects of CO2 Alteration in a Carbonate Rock

open access: yesInternational Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT CO2 injection in the subsurface is considered an option to improve oil and gas production and, more recently, to store CO2. Consequently, there is a need to better understand the interactions between CO2 and rock deposits. Among the primary deposit candidates are carbonate rocks.

Patient's Perspective and Change in Quality of Life After Stapes Surgery: A Multicenter Prospective Trial

open access: yesOtolaryngology–Head and Neck Surgery, EarlyView.
Abstract Objective This study evaluated outcomes of stapes surgery in otosclerosis patients by assessing audiometric results and health‐related quality of life (HRQOL) using the Dutch Stapesplasty Outcome Test‐25 (SPOT‐25) questionnaire. Additionally, the role of SPOT‐25 in preoperative decision‐making and as a follow‐up tool was explored.
