Sparking Interest in New Firework Colors

Sparklers are a favorite for holidays and celebratory events across the world, providing dramatic and eye-catching bursts of light. While their flames can span the rainbow, the actual sparks that fly and branch out are traditionally limited to dark red, gold, or white light. But chemists are now uncovering new ways to expand the pyrotechnic color palette using rare-earth metals.

Read the Full Paper

Sparks are tiny pieces of materials that, when heated to a certain temperature, produce visible light. Long-flying sparks formed from hot, incandescent metal particles are essential components of sparklers, fireworks, and other pyrotechnic spectacles—however, these traditional metallic sparks may leave something to be desired due to their limited color range. This is because the color of the spark is controlled exclusively by the temperature of the metal heated by surface combustion, a phenomenon known as black or gray body radiation.

In recent decades, studies have demonstrated the potential for rare-earth metals to be promising agents for more colorful pyrotechnic displays and spark variety due to their low boiling points and ability to burn in the vapor phase. Unfortunately, the metals are consumed very quickly during vapor-phase combustion, resulting in only brief flashes of light rather than the desired effect of long, branching sparks.

But now, a recent study published in ACS Omega reports that rare-earth metals in alloy powder form can produce flashes that shift from gold to green while maintaining continuous branching and sparking effects. This study is thought to be the first investigation into how such alloys expand spark colors beyond the black body limit, as well as their impact on branching behavior.

Overall, the researchers studied 11 commercial and synthesized alloys plus six rare-earth elements. They were able to achieve deep green spark segments based on eutectic ytterbium–zinc (Yb–Zn) and ytterbium–copper (Yb–Cu) powders. Once ignited, Yb–Cu burst into a shower of both gold and green sparks. In contrast to pure Yb, the Yb–Cu sparks successfully traveled outside of the flame, reaching significant lengths of 3–6 cm. The resulting effects appeared as a mixture of surface combustion (gold), vapor combustion (green flashes), and color-changing sparks with deep green and golden stages, repeating several times over.

In addition to color, the researchers demonstrated that rare-earth metal alloys could influence the branching behavior of sparks. Among the various candidates that were analyzed, the neodymium-iron-boron alloy Nd2Fe14B proved to be the most ideal and practical due to its stable phase and ability to produce bright, continuous branching effects. 

The authors conclude that binary metal alloys could one day play a vital role in enhancing the color variety and spark behavior of handheld sparklers and other pyrotechnic devices. However, further research and intensive safety testing must be conducted to ensure commercial viability.

So, as you stand under your next fireworks show or trace shapes in the cold night air with a sparkler, spare a thought for the chemists working to light up the skies and add color to our celebrations.

Need a Circuit? Just Print One

This article is based on a recent paper published in ACS Applied Materials & Interfaces, “Thermal Transfer-Enabled Rapid Printing of Liquid Metal Circuits on Multiple Substrates.”

Read the full paper here

As electronics evolve, their component parts—including circuits—need to as well. New research published in ACS Applied Materials & Interfaces describes a method to print functional liquid circuitry on all manner of objects and surfaces—from smooth ceramics to the dimpled skin of an orange—using a standard laser printer.

Flexible Circuitry: Finding a Solution that Sticks

Most circuit boards used today are built with rigid materials, but as electronics become more widely incorporated in malleable products such as items of clothing or soft robots, there is now a greater need for flexible, low-cost circuitry. Liquid metal circuits have shown to be a promising solution, but current printing methods have proven to be both expensive and complex, rendering them impractical for large-scale production. Xian Huang and colleagues at Tanjin University in China began exploring a new printing approach in hopes of developing a cheaper, more efficient way of fabricating liquid metal circuits for use across many different materials.

While liquid metals have been used for a variety of applications in flexible materials and electronics, their high surface tension often leads to pattern distortion and weaker adhesive properties—making it difficult to successfully print directly on curved or uneven surfaces. To improve this process, the researchers presented a more universal technique for creating circuit patterns on thermal transfer paper using a standard desktop laser printer and Cu−Ag-EGaIn—a liquid metal obtained by melting silver−copper microparticles in a gallium−indium eutectic alloy.

Turning Any Surface Into a Circuit Board

Similar to iron-on decals for transferring photos or images onto clothing, the carbon-based toner was laid down by the laser printer and then heat-transferred to a pane of glass. The toner patterns roughened the glass and created a hydrophobic gap of air between the carbon and the Cu−Ag-EGaIn liquid metal, allowing only the exposed parts of the surface to stick to the electronic ink-based pattern when the liquid metal was brushed on top. The resulting circuit could then be mounted directly onto smooth surfaces, or, after applying a flexible polymer coating, onto rougher materials such as the bumpy skin of an orange.

Regardless of how they were attached, the simple electronics tested in the lab—which included LED displays, sound sensors, and radio-frequency identification (RFID) circuits—all functioned as intended on their underlying surfaces. These included wettable substrates such as thermoplastic polyurethane and glass as well as low-adhesion materials such as knitted fabric, paper, wood, and fruit. By demonstrating a cheaper, easier method of producing liquid metal circuits, this new technology has great potential to expand flexible circuitry across applications such as consumer electronics, health monitoring, wearable devices, and more.

Metamorphosis in the Robot World

This article is based on a recent paper published in ACS Applied Polymer Materials, “Soft Tunable Gelatin Robot with Insect-like Claw for Grasping, Transportation, and Delivery.”

Read the full paper here

Research recently published in ACS Applied Polymer Materials describes a soft, magnetic millirobot inspired by the walking and grabbing capabilities of insects. But what are we going to do with a robotic caterpillar?

Millirobots are small-scale flexible robots with unique structures that allow them to roll or inch themselves forward, making them useful for applications such as targeted drug delivery, minimally invasive surgery, small-scale manipulations, and microfluidic devices. This may include work in hard-to-reach areas such as the gastrointestinal tract, which not only requires movement and navigation using a magnetic field, but also ease of removal or degradation. Unlike traditional rigid robots, soft millirobots do not have motors or joints that allow them to perform complex tasks, and therefore need special designs and structures to achieve advanced operations. 1-10

Conventional small-scale soft magnetic robots are usually made of polydimethylsiloxane or silicone rubber. While these materials are convenient for both fabrication and control, they are non-degradable, and their fixed mechanical characteristics limit fine-tuning of the robot’s properties for various purposes. However, researchers have now created a millirobot out of soft, biodegradable materials that can grab, roll, and climb—and then dissolve after its job is done. Inspired by the grasping movement of insects and mammals, they have been able to achieve independent control and demonstrate cargo transportation by a series of continuous operations such as nipping, rolling, opening, flipping, and releasing.11

The researchers developed this caterpillar-style millirobot using a gelatin solution mixed with microparticles of iron oxide. They achieved strength and solidity by cooling and then soaking the hydrogel in ammonium sulfate to cause cross-linking. Placing the material above a permanent magnet caused the microparticles to push the gel outwards, forming insect-like legs along the lines of the magnetic field. Because the iron oxide microparticles form magnetic chains within the gel, moving a magnet caused the legs to bend and produce a claw-like grasping motion.

In experiments, the material gripped a 3D-printed cylinder and a rubber band, and it was able to carry each to new locations. The team also tested the millirobot’s ability to deliver a drug by loading its legs with a dyed solution and rolling it through a stomach model. Once at its destination, the robot unfurled and released the dye with the strategic use of magnets.

Importantly, the millirobot easily degraded in water in just 48 hours, leaving behind only the iron oxide particles—which have no magnetic torque once the magnetic field is removed. The researchers say that the new millirobot could pave the way for new methods of drug delivery and other biomedical applications.

White Teeth Without the Toothbrush

This article is based on a recent paper published in ACS Applied Materials & Interfaces, “Fast Cross-Linked Hydrogel as a Green Light-Activated Photocatalyst for Localized Biofilm Disruption and Brush-Free Tooth Whitening.”

Read the full paper here

It’s not just a cliché that the first thing people notice about you is your smile: a 2010 survey found nearly half of us choose a great smile as a person’s most attractive feature.1 Furthermore, aspects of oral hygiene such as bad breath (89%) and yellow teeth (79%) took the lead for major turn-offs.1 Is there a chemistry solution for this very human problem?  

Globally, around 3.5 billion people suffer from oral diseases such as tooth decay and gum disease,2 many of which can be prevented through good oral hygiene. But traditional toothpastes remove only surface stains, and bleaching treatments can harm enamel. New research published in ACS Applied Materials & Interfaces reports on a novel hydrogel treatment that can break apart cavity-forming biofilms and whiten teeth without damage.

Current whitening treatments combine hydrogen peroxide gels with blue light, producing a chemical reaction that removes stains but also generates reactive oxygen species that can break down enamel and potentially damage exposed skin and eyes. Researchers at Nanchang University in China wanted to find a material that could instead be activated by a safer green light to both whiten teeth and prevent cavities.

The research team designed an injectable sodium alginate hydrogel membrane doped with bismuth oxychloride and cubic cuprous oxide nanoparticles to simultaneously achieve local tooth whitening and biofilm removal through a photodynamic dental therapy process.3 This was tested ex vivo on teeth stained with coffee, tea, blueberry juice, and soy sauce. Following treatment with the hydrogel and green light, teeth got brighter over time with no damage to the enamel. Additionally, the treatment killed 94% of bacteria in biofilms.

To demonstrate efficacy in vivo, the team used the new method on mice whose mouths were inoculated with cavity-forming bacteria, and they found that the new method prevented both moderate and deep cavities forming on tooth surfaces. The researchers report that their safe, brush-free treatment both effectively prevents cavities and whitens teeth, demonstrating a promising strategy for oral health care in the future.3
