The Paper Award GOLD: Visualizing material strain under pressure in 3D
Characterising the microstructure and strain in a material under applied force is crucial for evaluating its mechanical behaviour. However, it can be challenging to investigate force-induced effects in detail and at a high spatial resolution, especially when the deformations are reversible such as in elastic deformations.
As a solution, this year’s Paper Award GOLD winner, Shahrouz Amini and his colleagues from the Max Planck Institute of Colloids and Interfaces in Potsdam, Germany, developed a method called 3D-RISM. This method combines Oxford Instruments’ confocal Raman microscope technology with nanoindentation in one setup. It allowed the researchers to visualise elastic deformation fields (EDFs) in operando under a controlled indentation force at high resolution and even underneath the material’s surface.
Using 3D-RISM, Amini and his colleagues visualised the pressure-induced microstructure and strain in complex materials such as biological and geological calcites. Additionally, they were able to analyse the changes happening in the material with increasing force, when EDFs transformed into inelastic deformations.
The authors conclude that “3D-RISM can be an important step toward a quantitative understanding of the evolution of complex, elastic deformations” and “opens new avenues for unravelling the interplay between elastic anisotropy, materials’ microarchitecture, and mechanical performance in hybrid materials and microdevices”.
The Paper Award SILVER: Resolving secondary phases in next-generation battery materials
Searching for new cathode materials for lithium-ion batteries (LIBs) is an ongoing challenge with the goal of finding more sustainable materials that are independent of rare earth elements such as cobalt. One promising candidate is LNMO (LiNi0.5Mn1.5O4), however obstacles such as the interfacial instability and the formation of secondary phases during the high-temperature calcination step have so far prevented the adoption of LNMO in commercial batteries.
In the work recognised with the Paper Award SILVER, Umair Nisar and a team from the Centre for Solar Energy and Hydrogen Research Baden-Württemberg (ZSW) successfully characterised the secondary phases formed in LNMO using correlative Raman and scanning electron microscopy (SEM). While standard techniques such as XRD were limited in resolving the individual phases, Raman imaging allowed the researchers to find and identify the chemical nature of multiple secondary phases in LNMO materials.
In particular, in LNMO synthesised at 1000°C, Nisar and his colleagues detected three distinct secondary phases, which they observed for the first time. Higher amounts of these secondary phases resulted in a lower discharge capacity of LNMO. In contrast, the long-term cycling performance and rate capability were not affected.
The authors conclude that the insights from their work are “crucial for advancing the development of LNMO cathode materials for next-generation LIBs.”
The Paper Award BRONZE: Classifying cells for leukaemia diagnosis
Acute lymphoblastic leukaemia (ALL) is a form of cancer that affects blood and bone marrow cells. The early and precise diagnosis of ALL, along with the differentiation between its two main subtypes, B-cell ALL and T-cell ALL, is crucial for effective treatment and improved survival chances.
The Paper Award BRONZE winners, Patrycja Leszczenko et al. from the Jagiellonian University in Krakow, Poland, have introduced a Raman-based approach as a fast and reliable alternative to traditional ALL diagnostic methods. By applying statistical analysis techniques such as PCA and PLS-DA, which are increasingly used to evaluate Raman signals within complex biological samples, Patrycja Leszczenko and her team have identified distinctive molecular signatures in the protein-lipid profile of leukemic cells. The supervised PLS-DA technique successfully differentiated malignant cells from their healthy counterparts, even when employing different cell preparation methods.
This demonstrates the method’s reliability for diagnostic purposes and leads the authors to the following conclusion: “The potential translational applications [of Raman spectroscopy] in clinical practices offer a promising avenue for an expedited and accurate leukaemia diagnosis, paving the way for more targeted and personalised therapeutic approaches.”
