Abstract: The need for nanomaterials biosafety and risk assessment is an offshoot of the widespread use of nanoscale particle (NP)-derived materials in over 300 nanotechnology-based products already in commerce, including over 70 healthcarerelatedproducts (WWICS, 2006). Rapid advances in material sciences research and the advent of new and highly sophisticated nanofabrication technologies have…
Abstract: This article explores the relative merits of soft regulatory mechanisms (SRM), generally known as soft power diplomacy, as a catalytic conduit to promote global awareness of bioethical issues as it relates to biosecurity and dual-use research of concern (DURC). Based on a 2-year international panel workshopstudy evaluating the sociocultural and bioethical dimensions of future biosecu…
A vast spectrum of therapeutic interventions is based on stem cell technology, ranging from inert biomaterials to pluripotent, virally-modified cells. On the other hand, the scientific and regulatory community is concerned with the safety of stem cell-based products and therapies and the potential health risks associated with cell-based therapies. Scientific publications have revealed shared ge…
Abstract. The effect of zirconia polymorphs on the activity and selectivity of V2O5/ZrO2 for the alkylation of phenol with methanol has been investigated. Relatively pure monoclinic zirconia (m-ZrO2) and tetragonal zirconia (t-ZrO2) were prepared. A series of vanadium oxide supported on m- and t-ZrO2 with varying vanadium oxide content from 2.5 to 15 wt% were prepared by wet impregnation me…
