Since its discovery at the end of the nineties by Wang et al.,[1] the interest for light-induced superhydrophilicity is ever growing. The application fields for materials displaying such a property are wide and numerous:[2] self-cleaning surfaces, anti-fogging, anti-bacterial, water and air purification, microfluidics…Nowadays, a research emphasis is on relatively low energy bandgap semiconductors, targeting a higher efficiency under solar irradiation or more precisely in the near UV and low-end of the visible spectral range. Here, however, we report UV-induced superhydrophilicity in metal oxides thin films showing a relatively high transparency in the UV. Reactive ion beam sputtering (IBS) was used to deposit niobium, tantalum and titanium oxides thin films with thickness ranging from 10 nm to 120 nm on fused silica substrates at room temperature. Contact angle measurements were performed for progressively increasing UV doses and also as function of elapsed time after the termination of the exposure in order to investigate the UV-induced hydrophilicity and recovery behavior of tantalum and niobium oxide thin films in comparison to that of titanium oxide deposited in analogous conditions.

The Centre Spatial de Liege (CSL) was involved in the lyophilization process since 1991, when a large incident occurred to precious books from the National Archives. After a successful restoration, several further occasions took place up to now for freeze-drying flooded documents in vacuum chambers, normally devoted to space equipment testing. Customers range from ministries to particulars. Due to several drawbacks associated to the use of vacuum chambers in clean rooms, it has been decided to create a spin-off company (SVA - Special Vacuum Applications, Ltd) in charge of the operations, with its own equipment including a large vacuum chamber. A grant from the regional authorities has enabled to master various aspects of the document salvation process, including sterilization for the prevention of fungus and mould. The presentation describes the present and future equipment and processes associated with large scale lyophilization of damaged documents. [less ▲]

Vacuum freeze-drying of frozen wet papers was investigated experimentally. A freeze-drying facility was built to study the process by monitoring the various physical parameters (pressure, sample temperature, heater temperature, water content of the sample and cold panel temperature). A simple phenomenological model was developed to explain experimental results. The values of the physical parameters were optimized to make the process cost effective. [less ▲]
