Wood as a biological resource has a special porous structure that endows it with low strength. In addition, wood components are susceptible to changes in dimension under different humidities and are vulnerable to degradation by fungi. These disadvantages limit the full utilization of wood as a friendly environmental material. One effective way to solve these problems is to use unsaturated monomers for in situ polymerization within wood cellular pores, and thus to reinforce the wood components and prevent water from penetrating the cellular matrix as well as prevent attack by fungi. The challenge is the production of a polymer with high strength and even distribution within the wood cellular pores. The research by Liu YiXing and colleagues on page 13 better solves these problems and thus conveys good properties to low-quality poplar wood.

The cover image shows a scanning electron microscopy image of NaX zeolite crystals. This zeolite presents hydrophilic properties due to the low Si/Al ratio (1.23). As presented by L. Donato and colleagues on page 754, the NaX particles are used for the preparation of PDMS-based mixed matrix membranes. These systems are employed for the controlled release of ibuprofen. The release kinetics are modulated by the zeolite action, thus obtaining a linear release behavior. The investigated hybrid systems are very promising for applications as transdermal drug delivery devices.
