PEK14: A Kinesin‐4 Necessary for Male‐Derived Fertility in Arabidopsis thaliana
Cytoskeleton, EarlyView.ABSTRACT Of the 61 kinesins annotated in Arabidopsis thaliana, many are still without assigned function. Here, we have screened an insertional mutant library of Arabidopsis pollen‐expressed kinesins for fertility defects. Insertional mutants for three kinesins showed a significant reduction in seed set.

A Ray of Hope: Gamma Radiation for Microplastic Remediation
Global Challenges, EarlyView.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 ...

In Situ Gels for Nasal Delivery: Formulation, Characterization and Applications
Macromolecular Materials and Engineering, EarlyView.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.

Infrared spectroscopy across scales in length and time at BESSY II [PDF]
J. Synchrotron Rad. 31, 613-621 (2024)The infrared beamline at BESSY II storage ring was upgraded recently to extend capabilities of infrared microscopy. The end-stations available at the beamline are now facilitating improved characterization of molecules and materials at different length scales and time resolution. We report the current outline of the beamline and give an overview of the

Macromolecular Materials and Engineering, EarlyView.In soft capsules (SCs), four crucial factors can modify the properties of the shell: the shell formulation, its interaction with the fill material, the SC production and its storage conditions. Gelatin is the most used gelling agent for SCs nowadays, but they have some drawbacks which can be solved including other alternative polymers in the shell ...

The impact of microfibril orientations on the biomechanics of plant cell walls and tissues: modelling and simulations [PDF]
arXiv, 2015 It is known that the orientation of cellulose microfibrils within plant cell walls has an important impact on the morphogenesis of plant cells and tissues. Viewing the shape of a plant cell as a square prism or cylinder with the axis aligning with the primary direction of expansion and growth, the orientation of the microfibrils within the cell wall on

Morphology and Crystallization of Polypropylene/Microfibrillated Cellulose Composites [PDF]
KMUTNB International Journal of Applied Science and Technology, 2014 Microfibrillated cellulose (MFC) was prepared by controlling the re-precipitation of cellulose prepared in the mixture form of NaOH/Urea solubilized microcrystalline cellulose (MCC) and starch. The cellulose re-precipitation was carried-out in an HCl bath, resulting in a MFC form having relatively lower crystallinity than MCC.

Slow dynamics in a model of the cellulose network [PDF]
Polymer 48, 4849 (2007), 2007 We present numerical simulations of a model of cellulose consisting of long stiff rods, representing cellulose microfibrils, connected by stretchable crosslinks, representing xyloglucan molecules, hydrogen bonded to the microfibrils. Within a broad range of temperature the competing interactions in the resulting network give rise to a slow glassy ...
