“…In the last three decades, photocatalytic processes promoted by semiconductors (SC) have found a widespread application in many fields, including water splitting, energy production, air and water purification, surface sterilization and organic synthesis (17)(18)(19)(20)(21)(22)(23). The reasons for this increasing interest in photocatalytic protocols are the growing demand for reducing environmental pollution and for developing more eco-friendly and cheaper processes.…”

Int J Artif Organs ( 2011; : 9) 929-946 34 TITANIUM OXIDE AND ANTIBACTERIAL SURFACES IN BIOMEDICAL DEVICES Device-related infections: a clinical demand driving material science researchAn increasing number of clinical procedures requires the use of biomedical devices, whose widespread presence in modern therapeutic treatments is driving the demand for better performances and longer reliability. One of the major issues of both short-term devices and implantable prostheses is represented by device-related infections (DRIs) Accepted: August 31, 2011 rEViEW due to bacterial colonization and proliferation (1). About half of the 2 million cases of nosocomial infections that occur each year in the United States are associated with indwelling devices (2): these infections generally require a longer period of antibiotic therapy and repeated surgical procedures, resulting in potential risks for the patient and increased costs for the healthcare system. The planktonic bacteria that colonize a device surface tend to form a biofilm and the sessile bacterial cells, enclosed in a self-produced polymeric matrix of this kind, can withstand host immune responses and generally show extraordinary antibiotic resistance (3). Eventually, bacteria rapid multiply and disperse in planktonic form, giving rise

“…For instance, predictions show that in 2025, more than one billion people living in arid regions will face absolute water scarcity (1). While harvesting groundwater or freshwater from seawater is a clear way to address these issues, it might not be a straightforward or possible short-term option for populations with limited resources (2) and/or those living in remote areas. Therefore, beyond the purification of water, the concept of water reuse, and specifically potable water reuse, is becoming increasingly important.…”

Towards the use of metal–organic frameworks for water reuse: a review of the recent advances in the field of organic pollutants removal and degradation and the next steps in the field

Water reuse is becoming increasingly important as more and more areas in the world are facing water stress issues. Treatment of wastewater to attain the purity required for various usages from culture irrigation to drinking water is therefore key. Several water treatment options are already in place and while we will continue to use them, parallel efforts are required to: (i) address the removal of the most persistent chemicals in water and (ii) provide solutions for local communities. Recently, several studies on the use of metal-organic frameworks (MOFs) for the adsorption and photocatalytic degradation of organics in water have been reported. This enthusiasm originates from the large porosity and chemical tunability of MOFs -beneficial for adsorption -as well as their catalytic nature -beneficial for degradation. The present reviews proposes a comprehensive and critical analysis of the most recent studies on the use of MOFs for organics adsorption and photocatalytic degradation. The potential to use MOFs to catalyze the production of H2 from organic molecules, like water contaminants, is also addressed. Overall, the discussion is organised based on the type of organic pollutants targeted and encompasses those released in industrial, domestic and agricultural wastewater streams.3
