Vitamins are good for your multi-energy nanogenerator

spectrometerResearchers report a simple, innovative and inexpensive design of a vitamin-based hybrid biocompatible nanogenerator with energy harvesting ability from various energy sources in a single device. This is the first time that inexpensive and biocompatible vitamin B2 has been used as a novel and effective beta-phase stabilizer to enhance the piezoelectric performance of PVDF. The attractiveness of using vitamin B2 is that it is biodegradable and biocompatible, thermodynamically stable, low-cost, has delocalized pi-electrons, contains multiple numbers of hydroxyl groups, carbonyl groups and amino groups in its backbone.

Using DNA molds for templating nanoparticles into 2D patterns

nanopatterningDNA nanotechnology employs DNA as a programmable building material for self-assembled, nanoscale structures with precisely controlled structures, that can lead to improved surface properties relevant to biosensing, materials science, and cell biology. Adding to the available tools for DNA nanopatterning, researchers have demonstrated a novel biotemplating strategy for ordering various nanoparticles into expected two-dimensional (2D) patterns via nanoparticle-surface or nanoparticle-DNA interaction.

Plate-like ferroelectric crystals synthesized with the help of MXenes

2D_ferroelectric_crystalPotassium niobate (KNbO3) is a a perovskite ferroelectric crystal that, due to its optical properties, has been found useful in many different areas of materials science research, including electro-optics, piezoelectric, and electronic applications. Researchers have now, for the first time, succeeded in producing large KNbO3 crystals with uniform flat shape, and c-axis texture, which makes the crystals useful for practical electro-optic applications. By using MXenes as precursor materials to grow ferroelectric crystals, their 2D nature is inherited by the ferroelectric crystals.

Smart droplets clean and repair surfaces

nanoparticles_on_surfaceResearchers report a fluid-driven nanoparticle transportation clean-and-repair approach that reveals a novel self-healing system that conserves matter, behaves autonomously, and is implemented easily. Debris resting on a substrate is relocated, in one step, from undamaged to damaged regions of the substrate, using functional droplets that recognize and transport the nanoparticles. This simultaneous clean-and-repair approach reveals a novel self-healing system that conserves matter, behaves autonomously, and is implemented easily.

Large-scale synthesis of metal nanoclusters with thermal shocks

nanoclusterResearchers report significant advances in developing a high-temperature, fast nanomanufacturing technique for the large-scale production of ultra small metal nanoclusters decorated in a graphene host matrix. The size and morphology of the metal nanoclusters can be controlled by varying the reaction temperature and the mass loading of metal salt in the graphene aerosol nanoreactors. This one-step continuous aerosol-based thermal shock technique offers considerable potential for the manufacturing of well-dispersed and uniform nanoclusters stabilized within a host matrix.

Material systems used in 4D printing

4D printing allows a 3D printed structure to change its configuration or function with time in response to external stimuli such as temperature, light, water, pH, etc. The basic idea is to manipulate materials at nano and micro levels in order to produce, via 3D printing, materials that can modify their structures over time at the macro level. Based on 4D printing, 3D printed objects from nano- to macroscale can be fabricated as smart devices, metamaterials, and origami for various functional applications in prototype, aerospace, biomedicine, etc.

Nanotribological printing - a novel 3D nanotechnology fabrication technique

nanostructureA novel nanoscale additive manufacturing technique termed Nanotribological Printing creates structures through tribomechanical and tribochemical surface interactions at the contact between a substrate and an atomic force microscope probe, where material pattern formation is driven by normal and shear contact stresses. This technique advances the field of nanomanufacturing by providing a versatile and easily accessible method for creating complex (multi-material) nanostructures, with high precision and uniquely superior mechanical properties.
