How advanced nanotechnology drives ultrathin membrane development for separations

Driven by advanced nanomaterials and nanofabrication technologies, tremendous progress has been made over the last 15 years in making ultrathin membranes based on a variety of advanced nanomaterials and nanotechnologies. Further pushing membrane thickness to sub-50 nm or even atomic level is appealing to researchers, with the ultrafast permeance that may be enabled and ultimate understanding of formation and transport at the extremely low thickness that can be significantly different from their thicker counterparts.

Combination of engineered resonators and nanotechnology for sensing hazardous environments

resonatorResonance-based sensors can be used as an advanced tool for gas sensing as they show several advantages as compared to conventional gas sensors like metal-oxide semiconductor and electro-chemical gas sensors. With the introduction of an additional metamaterial layer over the sensor, the selectivity of these sensors can be improved. These article focuses mainly on metamaterial-based split ring resonators (SRR) and complementary SRRs (CSRRs) structures used in several sensing applications.

Nanotechnology versus viruses

nanocarrierA recent review article highlights how nanoscience and nanotechnology can solve three acute problems in the treatment, prevention, and diagnosis of viruses like SARS-CoV-2: 1) synthesis of novel drugs and vaccines based on nanocarriers with enhanced efficiency and reduced side-effects for the treatment of the current pandemic and the prevention of future virus attacks; 2) design of protective equipment based on nanoparticles, such as medical face masks and outfits and 3) development of nanobiosensors for early detection of infections in a maximally efficient way.

Shape-shifting slimebots (w/video)

slimebotCombining the benefits of both fluid and solids, researchers have demonstrated various functions for their slimebots, including navigation in narrow channels much smaller than their size; object capture operations via the curl or endocytosis modes; and circuit repair and controlled switching using their own conductive properties that can even be reconfigured as self-healing strain sensors for monitoring human motion. The widely applicable working environment of these novel magnetic slime robots make them promising for future applications in biomedical and wearable devices.

A cost-effective and lithography-free method for printing optical metasurfaces

metasurfaceA lithography-free method for printing optical metasurfaces with resonant laser printing can achieve metasurfaces for structural colors, optical holograms, and diffractive optical elements, with an energy consumption of less than 1 nanojoule and a print time down to 1 nanosecond per dot. The performance of this ink-free laser color printing with a resolution of more than 100 000 dpi by far exceeds the output of conventional laser printers. The nanoscale structures made on a multi-layer film are robust and typically could last longer than most inks or pigments.

Kirigami-style, self-folding circuit boards

cubic-PCBResearchers demonstrate rapid cutting and folding of a printed circuit board (PCB) into complex 3D electronics using only a simple laser cutter. This origami manufacturing technology has the potential to allow faster and cheaper production of 3D electronic devices based on thin shells such as antennas that are poorly suited for current 3D printing methods. The technique relies on a method known as laser forming, where heat from a focused laser generates bending within a target.

High-comfort smart face mask checks for proper fit and monitors coughs

face-maskResearchers have developed a multifunctional wireless smart mask, capable of identifying mask-wearing conditions and monitoring the frequency and pattern of coughing - which is a common symptom of many respiratory diseases. This novel smart mask is capable of simultaneously monitoring coughs and mask-wearing conditions in a remote and battery-free manner, and most importantly, it provides excellent wearing comfort and breathability. The mask fabric is embedded with a soft and battery-free radio-frequency harmonic transponder that enables continuous, real-time wireless monitoring of coughs and mask wearing.
