India’s commitment to its ambitious technology goals brings a unique opportunity for the materials science community in the country to achieve synergy, focus, large-scale employment and global impact. However, scientists need to engage more spontaneously in goal-oriented collaborations along with stakeholders in industry and government.
As new materials and manufacturing techniques are discovered, their benefits transform every branch of science and engineering. In spacecraft propulsion, a new generation of ion engines could provide unprecedented performance and flexibility in space mission design.
Nanoparticles (NPs) administered in the human body will undergo rapid surface modification upon contact with biological fluids driven by their interfacial interaction with a diverse range of biomolecules. Such spontaneous self-assembly and adsorption of proteins and other biomolecules onto the NP surface constitute what is commonly known as the protein or biomolecule corona. This surface biotransformation of the NPs modulates their biological interactions and impact on physiological systems and can influence their overall pharmacological profile. Here, we comment on how the initially considered ‘nuisance’ of the in vivo corona formation can now be considered a nanoparticle engineering tool for biomedical use, such as in endogenous tissue targeting, personalized biomarker discovery and immunomodulation.
Solar photovoltaics has tremendous potential to address current gaps in electricity access for resource-challenged settings, such as sub-Saharan Africa. However, a rapid surge in installations and future growth will lead to an increase in waste from panels and batteries, which needs to be tackled urgently. Innovative technical solutions and improved policies and standards are required to address end-of-life challenges for solar photovoltaics in sub-Saharan Africa.
Material World: A Substantial Story of Our Past and Future, the latest book by Ed Conway, explores the materials that underline our modern civilization, discussing their supply and manufacturing, but also history and innovators.
Materialism, a podcast exploring the past, present and future of materials science, is turning five. Co-founders and co-hosts Taylor Sparks (a professor at the University of Utah) and Andrew Falkowski (a PhD student in Sparks’ group) discuss how they use storytelling to create compelling episodes and share their journey and lessons learned.
Minimally invasive surgery (MIS) lacks sufficient haptic feedback to the surgeon due to the length and flexibility of surgical tools. This haptic disconnect is exacerbated in robotic-MIS, which utilizes tele-operation to control surgical tools. Tactile sensation in MIS and robotic-MIS can be restored in a safe and conformable manner through soft sensors and soft haptic feedback devices.
The production of conventional meat contributes to climate change and uses up around 70% of available arable land. Cultured meat is emerging as a potential solution, but presently can be only produced at the pilot scale. Biofabrication technologies developed for biomedical applications could be leveraged to introduce automation and standardization in the production of cultured meat, accelerating its path to market.
An article in Nature Electronics introduces a single-step platform for integrating 2D materials into functional devices, addressing a fundamental constraint in van der Waals integration.
An article in Advanced Healthcare Materials reports a 4D-printed hydrogel dressing that shrinks at body temperature and promotes healing in chronic diabetic wounds.
An article in Science reports an exceptionally warm and thin sweater knitted from stretchy aerogel fibres, whose core–shell structures are inspired by the fur of polar bears.
Biochar is proposed as a promising solution for sustainable development, but proper risk management and careful evaluation are essential when considering its use. It is crucial to acknowledge the limitations of biochar and recognize that it is not a magic bullet for green technologies.
