Researchers have developed an effective and environmentally benign method to combat bacteria by engineering nanoscale particles that add the antimicrobial potency of silver to a core of lignin, a ubiquitous substance found in all plant cells. The findings introduce ideas for better, greener and safer nanotechnology and could lead to enhanced efficiency of antimicrobial products used in agriculture and personal care.
Publication of the report 'Nanotechnologies for pesticides and veterinary medicines: regulatory considerations' marks the culmination of four years of APVMA-led research, consultation and collaboration.
Researchers have designed a nanoparticle transport system for gene delivery that destroys deadly brain gliomas in a rat model, significantly extending the lives of the treated animals. The nanoparticles are filled with genes for an enzyme that converts a prodrug called ganciclovir into a potent destroyer of the glioma cells.
Graphene Week 2015 in Manchester last month saw the launch of Women in Graphene, a support network for women in graphene and related 2D materials research. As in other areas of science and engineering, women make up significant proportion of the 2D materials workforce, but they face a number of gender-specific barriers to career progression.
Scientists report a 250% increase of the thermoelectric conversion efficiency of a CrN thin film compared with the bulk material. This work paves the way for a new generation of thermoelectric materials based on oxides and nitrides.
