Cobalt Oxide Neurotransmitters
Kampara Roopa Kishore,
SASTRA Deemed to be University, Thanjavur, Tamilnadu, India
The image shows electrospun biomimetic polyvinyl alcohol (PVA) - cobalt oxide (Co3O4) nanofibers as human brain neurotransmitters. PVA and cobalt (II) chloride hexahydrate were used for the synthesize of PVA-Co3O4 nanofibers by electrospinning technique, which resembles human brain neurons.
The interconnection of nanofibers looks like the nucleus of a neuron and the elongated nanofiber morphology replicates the axon of the neuron. PVA-Co3O4 nanofibers with high surface area to volume ratio had many applications in gas sensors, catalysis, fuel cells, and energy storage applications. These PVA-Co3O4 nanofibers had shown good vapor sensing response towards methanol vapor, for the concentration ranging from 21 ppm to 2094 ppm at 350 °C operating temperature. PVA-Co3O4 nanofibers were characterized by a field emission scanning electron microscope. The width of the image is 0.075 mm.

Firedrake
Kartik Nemani, Prasanna Rudravajula, Purdue School of Engineering and Technology, IUPUI, Indianapolis, IN, USA
A partially etched MXene flake morphed into the shape of a rising dragon from the smoke. The dragon named “Firedrake” with blue blood bleeding out of its forehead, seeks the moonlight to rejuvenate and regain its strength. This is inspired by our childhood when I was a fiction addict and read Cornelia Funke’s 2004 Adventure Fantasy novel “The Dragon-Rider”. Artificial eye and tongue are added to highlight features of the image. The image width is 0.005 mm.

Precipitation of Life
Shivam Kumar Dwivedi, Abishek M, Indian Institute of Technology Madras, India
This is the microscopy image that resembles precipitating chemical reaction. The term ‘precipitation reaction’ can be defined as “a chemical reaction occurring in an aqueous solution where two ionic bonds combine, resulting in the formation of an insoluble salt”. These insoluble salts formed in precipitation reactions are called precipitates. It is the chemical reaction between potassium chloride and silver nitrate, in which solid silver chloride is precipitated out. This is the insoluble salt formed as a product of the precipitation reaction in the same manner life is also a precipitation of birth & death.

Kaleidoscope
Bernardo Cesare – Dept. of Geosciences, University of Padova, Italy
This photo tells us of a geological event half a billion years ago, when extreme heat deep within the Earth gave rise to this crystal formation. Like a stained-glass window, the black graphite cuts across the colorful panels of quartz and feldspar. Feldspar is the most abundant silicate (of Al, K, and Na) of the Earth’s continental crust. I use photomicrographs to study rocks and minerals, not only to make images with artistic intent. In this case, I actually studied - with colleague and friend Satish Kumar - this granulite rock from a working quarry in Kerala, India. The microscopic scene that we observe formed at almost 900 °C when the feldspars crystallized together with graphite in this beautiful intergrowth. While most minerals, including all silicates, become transparent to light when thinned down at 30-micron width, some remain opaque. Graphite is among them, and this explains why it creates the black strokes in this photo. The image width is 2.7 mm.

Underwater Nano Flower Portrait
Yuxin Wen & Phil Ridley, Drexel University, Philadelphia, PA, USA
This portrait demonstrates nanoflakes of a layered potassium vanadium oxide bronze (KVO) phase arranged in a unique way, resembling an all-encompassing, magnified flower. The petals of the nano flower are delicate and dynamic, and the luminance on the edges of the petals evokes a supernatural feeling. In effect, the flower is reminiscent of serendipitous creatures submerged deep under the ocean, calling courageous divers for further adventures. The authors of this photograph added the purple-blue color gradient to emphasize the sense of movement and mystery and to draw attention to the unfathomable center of the flower. This unique material morphology is owed to the novel synthesis approach used where transition metal carbide MXene is converted into this layered KVO phase via controlled oxidation. The image width is ~ 0.01 mm.

Autumn Leaves of Carbon Nanotubes
Juan Luis Fajardo Díaz, San Luis Potosí Institute of Scientific Research and Technology, San Luis Potosí, Mexico.
Material: carbon nanotubes (CNTs)
Image size: The image width is 0.11 mm.
This image illustrates carbon nanotubes (CNTs) formation that resembles a leaves interaction like the fallen leaves of a tree. The combination of colors like dark green, yellow, and red simulating colors of autumn leaves fit very well with the spatial distribution, curved sections, hills, and structure obtained from the CNT.
These CNTs grew over a Co-Cu thin film in a chemical vapor deposition system. The combination of a sulfonated and oxygenated precursor, temperature variation, reductive atmosphere, and time of synthesis modifies the growth mechanism of Co nanoparticles. It creates very short and thin CNTs that agglomerates and display these peculiar patterns over the sample. This effect is probably associated with a specific decomposition process of the sulfonated and oxygenated precursor and the interaction with Co and Cu catalysts.

A Crystalline Silver Flower
Material: Silver nanoparticles on a silicon substrate
Image size: The image width is ~ 0.1 mm.
Image description by the scientist/artist: A thin and delicate layer of silver nanoparticles has been shaken by ionized gas. This energetic gas strongly interacts with the surface and modifies the fabric of the matter. As a result, the spheres change their shape and slow growth to form sharp structures well distributed on the surface. These poetic flowers spread over the silicon surface like fragile emerald crystals. Here, by using scanning electron microscopy, we discover the beautiful organization of these tiny particles on a purple carpet.

The Micropastita
Kanit Hantanasirisakul, Drexel University, Philadelphia, PA, USA
The micropastita is a scanning electron microscope image of a metallic fabric used for wearable electromagnetic interference (EMI) shielding application. Typically, a metal foil such as aluminum or copper is used to protect electronic devices against electromagnetic waves to enhance device performance and stability. However, wearing cloth made of aluminum foil won’t be so comfortable (except you need it for your Halloween costume!). Therefore, there is a growing interest in developing fabric with metallicity (high electronic conductivity) for wearable EMI shielding applications. The width of each “micropasta” is 0.01 mm.

Sweet Tubes
Ricardo Tranquilin, Federal University of Sao Carlos, Brazil
The general idea of this work is the association of nature with microscopic images, both in their shapes and colors, so it is possible to converge the microscopic world to the common world, where so we can show that this small world works with the same forms of the macro world. Also take a special look at the images that exhibit abstract forms. The material presented in this image is tungsten trioxide.

A Polymer Whirled
Sarah Gleeson, Drexel University, Pennsylvania, USA.
This image shows the cross-sectional edge of a polycaprolactone coating, captured with a scanning electron microscope. This coating creates a neutral surface on a polycaprolactone-block-poly (acrylic acid) single crystal film, to prevent mineral overgrowth when placed into a body-mimicking ion solution. The semicrystalline polymer film is typically characterized by hard jagged faces and distinct striated lamellae. It was striking to see this portion of the coating which had coiled upon itself after being fractured, creating beautiful concentric wrinkles against a smooth polymer backdrop. Image width is 0.055 mm.
