No 6 The journal towards revealing microscopic world of mouse sagittal suture
Fiona Zhang, Research Student | Vote now for No 6 >>
Calvarial suture is an important but understudied interconnective tissue that is essential in handling the rapid expansion of neurocranium as well as protecting it. The images show the processes of preparing and scanning the sagittal suture of a 28-week-old male mouse. The light microscopy reveals the morphology in the sagittal plane and confocal laser scanning microscopy illustrates the osteocyte network in the corresponding location. The osteocyte network distributes in both bone fronts in an asymmetrical fashion, where lower canaliculi density appears in the lower bone front. The canaliculi density increases away from the sutural gap, with a lamellae-like organisation of the orientation and sequencing of the lacunae. The microscopic features are important for understanding the perilacunar-canalicular remodelling related to mineralization and organic matrix generation, potentially shed light on the management of cranial disorders like.

No 9 From Dust to Ashes: Growing planets in unstable protoplanetary discs
Adrien Houge, Early Career Researcher | Vote now for No 9 >>
Planets form in discs of dust and gas surrounding young stars. Their formation begins with a crucial process, so-called dust coagulation, during which tiny dust grains inherited from the interstellar medium grow into large aggregates able to build planets. However, the evolution of protoplanetary discs is punctuated by violent accretion outbursts, during which the temperature of the disc increases by several factors for ~100 years. During these events, the dust aggregates are heated, causing the sublimation of their ice content (e.g. water ice), and potentially destroying them.
No 10 Re-entrant Honeycomb Steel Reinforcement
Emmanuel Momoh, Early Career Researcher | Vote now for No 10 >>
The “Re-entrant honeycomb steel reinforcement” is an Auxetic Structure – meaning that it expands in the lateral direction when stretched axially and contracts laterally when compressed axially, thereby resulting in a negative Poisson’s ratio. This counter-intuitive behaviour results in such reinforcements having a very wide range of potential benefits such as the ability to naturally assume double curvatures, better energy absorption, lateral confinement, and improved bonding with cementitious matrices. Although this phenomenon has resulted in a proliferation of research in the use of auxetic materials in cementitious construction, the use of auxetic reinforcement in concrete for structural applications, has not been fully harnessed. Our study, therefore, explores the application of auxetic reinforcements in cementitious construction materials.
No 11 Tails of discovery
Daniela Lazaro Pacheco, Early Career Researcher | Vote now for No 11 >>
In our research, we study the way that different movements and loads affect the health of the intervertebral disc in the spine. And we do this using oxtails. The image shows two oxtails, freshly collected from the abattoir. Getting the tails swiftly to the lab ensures that the cells within these tissues are still pulsating with life.
We delicately remove surrounding muscle and ligaments to isolate the bone and intervertebral disc. A tail disc then finds its way into our bioreactor, a test system that allows us to simulate the living environment of the human disc, including how the disc moves during different daily activities. We can use this to understand how loading affects the cells and the overall disc health, and whether different lifestyles will nurture the disc or hasten degeneration. These answers will also illuminate a path to test the effectiveness of cutting-edge treatments like regenerative therapies.

Dee Pothinual, Research Student | Vote now for No 12 >>
A photo of atomically thin flakes of hexagonal boron nitride under a microscope at 50 times magnification is shown. Hexagonal boron nitride (hBN) is a material that is increasingly used to fabricate 2-dimensional semiconductors in nanotechnology. hBN when combined with other 2-dimensional materials like graphene and Transition Metal Dichalcogenides (TMDCs) is utilised to create a Single Photon Emitter (SPE) which is a building block in the manufacture of transistors, diodes, and integrated circuits. An SPE gives off one photon per cycle of electron excitation. As a host material, hBN can generate visible light under ambient conditions. The thickness of a monolayer flake is around 1/20,000 of the width a human hair. A monolayer flake is mauve, while thicker flakes are blue, green, and yellow.

Qian Yu, Research Student | Vote now for No 13 >>
The development of solvent-minimised synthesis is crucial to decreasing dependence on traditional hazardous routes of metal-organic frameworks (MOFs). This work explored the green synthesis of a copper trimethyl 1,3,5-benzenetricarboxylate (CuBTC or HKUST-1) MOF using mechanochemical synthesis by ball milling as shown in the photo. We employed a design-of-experiment (DoE) approach to systematically investigate the effects of various synthesis factors, rotational speed, weight of starting material, rotational time, DMSO amount, ball to powder ratio and standing time, on the characteristics of CuBTC. This method was focused on optimizing CuBTC key properties of crystal size, yield, and specific surface area. Here, the SEM images was provided to show the CuBTC samples obtained from different synthesis condition, which exhibit noticeable dissimilarities. This observation suggested that increasing the amount of added DMSO could enhance the surface smoothness of the crystal, as DMSO could buffer the crush between balls and materials during synthesis process.

The image is the sample of Silicon carbide (SiC), which is a widely used ceramic material for high-temperature and high-power applications due to its excellent properties, such as high hardness, high thermal conductivity, and low thermal expansion. and the image is obtained by Scanning electron microscopy (SEM) which is a powerful technique to investigate the microstructure and morphology of samples. In this image, I present a SEM picture of a SiC sample that has a sunflower-like shape. The sunflower shape of the SiC sample may be related to its growth process or its crystal structure. I found this image by sheer luck and coincidence, but it is really interesting and worth sharing.
No 15 Intervertebral Disc Degeneration
Edgar David Rivera Tapia, Research Student | Vote now for No 15 >>
Back pain is a common condition, often caused by severe degeneration of the intervertebral disc, which is the connective tissue between adjacent vertebrae in the spine. Damage to the microstructure of the intervertebral disc can change the mechanical properties, which may lead to the progression of degeneration.
The intervertebral discs were loaded in different ways, and then imaged by polarised light microscopy to assess the damage to the different structures of the disc such as delamination between the different layers in the outer region of the disc (*), tears within the layers or voids in the central region of the disc ( ). This allows us to quantify the damage caused by different loading conditions, which will help us to develop suitable models for degeneration. These models can then be used to provide a better understanding of how degeneration occurs and can be used to evaluate new ways to treat it.

Pursuing renewable energy sources has become increasingly imperative in achieving net-zero emissions, particularly within a society grappling with the dire consequences of pollution, surging electricity costs, and the inexorable ramifications of global warming. To this end, using sustainable materials capable of generating renewable energy holds great promise. Among these materials, thermoelectric substances have emerged as particularly intriguing, as they can directly convert heat into electrical energy. By incorporating thermoelectric materials into windows, it becomes possible to harness the natural temperature disparity between a building's interior and exterior, generating power.
However, it is noteworthy that high-efficiency thermoelectric materials are marred by toxicity, exorbitant cost, and scarcity.
The accompanying image showcases our noteworthy achievement in fabricating transparent, eco-friendly, cost-effective thermoelectric glazing boasting exceptional efficiency. This groundbreaking glass design holds the potential for large-scale production. It is a viable alternative to conventional windows, providing buildings with a sustainable energy source and curbing heat loss through windows.
No 17 Once upon a spine
Isabelle Ebisch, Research Student | Vote now for No 17 >>
Intervertebral disc degeneration is one of the main reasons people suffer from chronic back pain, often resulting in years lived with disability. Yet our ability to test innovative therapies and devices to treat degenerative disc disease is limited, and the testing often does not translate to the real world. Therefore, we have built a “spine simulator” that allows us to replicate the environment of the intervertebral disc in the spine as realistically as possible in a controllable lab setting. The simulator can move, bend, and twist to replicate different daily activities such as walking, sitting, and sleeping. We are using this to investigate causes for disc degeneration such as the influence of different lifestyles, and it may even allow us to identify movements and exercises that promote disc health.

Observe the beauty of the polymeric spherulite structure captured in this extraordinary image of PEEK (Polyetheretherketone) through the lens of a scanning electron microscope. Polymers are long chains of repeating units, and when they are cooled from the melt, they can undergo the process of crystallization. When PEEK undergoes crystallization, it arranges its polymeric chains into ordered lamellae branches, which form several radial structures called spherulites. In this magnified view, a symphony of intricate spherulites unfolds, each displaying a distinct pattern of radial growth, just like ripples in a pond. The complex surface invites closer inspection, revealing interconnected filaments and delicate boundaries, evoking a sense of order and harmony. This microcosmic marvel showcases the intricacies of PEEK's structure and the incredible capabilities of scientific exploration, reminding us of the hidden wonders that lie beyond the reach of our naked eye.

In our research project aimed at assessing the condition of pipes, our objective was to convert human-made pipes into eco-friendly wonders. Working alongside our dedicated team of nature inspectors, we were fortunate to have the delightful presence of our furry companions who reside near the laboratory. These precious friends possess a deep fascination for the project that benefits our planet. To ensure their safety and well-being, I always insisted that they wear a lab coat. While we couldn't provide them with their own mini lab coats, they kindly asked us to place one of the pipes outside so they could inspect the sensor connections. Additionally, they affectionately requested some nutty cookies as a token of appreciation for their efforts, thereby granting us their adorable seal of approval.

“Break” is what we all know in word, where we could imagine this word’s definition by remembering a scene from our memories. The question is had you ever see how it really looks like? The flames that consume living things in their eternity or a blood that boils due to the extreme heat.
This image gives us a microscopic view of the shattering of a PVC hourglass sample after tensile testing in a University of Exeter lab. It is seen how a 10×10 mm part of the sample breaks, turning blossoms into ash like a dragon's breath.
The research has improved our understanding of what a break is, as well as how to recognise pipe breakage modes by navigating this strange world of stretchable and flame-like patterns. Pipes which bring us the symbol of purity and life, Water.
