New cover out! Due to the twisted side-chains this hole-transport layer molecule can protect the #perovskite layer from hygroscopic dopants and enhance the charge transfer thanks to the generation of a strong interfacial electric field. Great work Maning Liu, Paola Vivo and coworkers!

There’s so much we can learn from extracellular vesicles (EVs)! Dr. Clàudio Pinheiro at Ghent University developed a series of tools to help standardizing research on EVs. It was an honor to represent the results of his work in a cover for his PhD thesis.
In this cover droplets of a biofluids turn into EVs, which then becomes information and connect to each other. This emphasizes how the analysis of biofluids and EVs can provide a network of information, fundamental for the research development. EVs are nanosized particles present in biofluids that can carry biomolecules and are extremely important for biological functions. However, the diversity of methods and protocols for their analysis pose a challenge for rigorous and reproducible research. Therefore, the development of a standardized toolbox to use in EV research is an important step towards a better understanding of EVs and their function.
Excited to see the future of this!
Nanostructured materials are extremely fascinating. At the nanoscale, materials exhibit new properties and behaviors, which can be exploited for a wide range of applications in almost every branch of technology. For this, however, it is crucial to achieve control over the growth process.
This image represents the different growth steps of GaAs nanoridges by metal–organic vapor-phase epitaxy (MOVPE). Nicholas Morgan and the group of Anna Fontcuberta-i-Morral at EPFL investigated the process and developed a kinetic model to accurately describe the evolution of the nanoridges morphology at the different stages. This allows a high level of control over the production of nanoridges with different features and highlights the advantages of MOVPE compared to other growth techniques.

It was super interesting to work on this cover for the group of Paola Vivo at Tampere University! This perspective highlights the role of wide bandgap #leadfree #perovskite-inspired materials in #IndoorPhotovoltaics. Research on Pb-free wide bandgap perovskite for indoor PV is still at early stages, but it has great potential to become an efficient and sustainable alternative to power IoT devices that we use in our daily life.

Thrilled to see this very interesting work by Giorgia Greco and colleagues represented as frontispiece for Small Methods! For the first time SAXS/WAXS techniques were used for an in-depth characterization of the AlCl4 anions intercalation process in graphite.

New cover for Journal Of Physical Chemistry B! Dr. Alexander Korotkevich and Dr. Carolyn Jil Moll from the group of Prof. Huib Bakker at AMOLF show how sum frequency generation (SFG) spectroscopy can reveal the molecular orientation of anions at the water-air interface.
SFG is a powerful technique which can be used to analyze surfaces and interfaces. The cover represent the SFG generation process upon interaction of 800 nm and infrared light with carboxylate anions at the water–air interface. The background shows imaginary χ(2) spectra collected in SSP and SPS polarization combinations that reveal the molecular orientation of the anions.

A representation of catalysis in MINT condition. Macrocycles are mechanically interlocked to carbon nanotubes, thus regulating their catalytic activity.
Inspired by the work of Emilio M. Perez (imdea).
New cover out! Read about how #perovskite stability is increased by using a novel hole transport material that forms a compact and adherent layer, thus acting as shield against moisture.
Super interesting work by the group of Paola Vivo at @tampereuni.

Representation of core-shell lanthanide doped #nanoparticles for #upconversion (UCNPs) capped with oleic acid.
UCNPs can absorb two or more low energy #photons and convert them into one photon with higher energy, which is then emitted. As-prepared UCNPs are usually capped with hydrophobic oleic acid to prevent aggregation with other nanoparticles and to control their growth.
They are of particular interest for bio-imaging, bio-sensing and nanomedicine, but also for photovoltaic applications.

According to #QuantumMechanics the position of #electrons in an #atom cannot just be simply described by particles rotating around the #nucleus. Their location is indeed given by a function called #AtomicOrbital, which calculates where it is more probable to find electrons of a specific energetic level. Different orbitals are identified by letters (s,p, d and f) and generally visually represented in a simplistic way by “clouds” of a specific shape: the simplest - s - is a sphere, p is a sort of dumbbell, and d and f orbitals have more complicated shapes.
Here I represented the Li, C and Si atoms with their orbitals, where s orbitals are in blue and p orbitals in orange/yellow.
The group from Esther Alarcon Llado at @_amolf works on #nanostructures for #photovolaic applications. This figure was inspired by one of the first works from the group, where Cu was grown on Au through #electrodeposition (https://doi.org/10.1039/C9NR05574F). On the bottom a more colorful reinterpretation :) Which one do you like more?
