A Ray of Hope: Gamma Radiation for Microplastic Remediation

open access: yesGlobal Challenges, Volume 9, Issue 6, June 2025.
Gamma irradiation is a promising method for degrading microplastics in sewage sludge. Cobalt‐60 doses up to 116 kGy are used, achieving over two‐thirds degradation at the highest level. With further optimization, gamma irradiation could improve wastewater treatment sustainability by minimizing microplastic presence in biosolids and protecting ...

MODULUS OF ELASTICITY AND HARDNESS OF COMPRESSION AND OPPOSITE WOOD CELL WALLS OF MASSON PINE

open access: yesBioResources, 2012
Compression wood is commonly found in Masson pine. To evaluate the mechanical properties of the cell wall of Masson pine compression and opposite wood, nanoindentation was used. The results showed that the average values of hardness and cell wall modulus

Optimal Decomposition and Recombination of Isostatic Geometric Constraint Systems for Designing Layered Materials [PDF]

open access: yesarXiv, 2015
Optimal recursive decomposition (or DR-planning) is crucial for analyzing, designing, solving or finding realizations of geometric constraint sytems. While the optimal DR-planning problem is NP-hard even for general 2D bar-joint constraint systems, we describe an O(n^3) algorithm for a broad class of constraint systems that are isostatic or ...

In Situ Gels for Nasal Delivery: Formulation, Characterization and Applications

open access: yesMacromolecular Materials and Engineering, Volume 310, Issue 6, June 2025.
Drug delivery through the nasal route offers many advantages, but is hampered by a number of challenges, such as the short drug retention time caused by mucociliary clearance. In situ forming gels, which undergo a sol‐to‐gel transition with specific triggers at the site of action, present real opportunities in this field.
