Highly emissive organic solids with remarkably broad color tunability based on N,C-chelate, four-coordinate organoborons
Molecular fluorophores based on N,C-chelate, four-coordinate organoborons exhibit tunable solid-state emission colors that cover the whole visible region from blue to red. The emission color can be tuned through the substituents on either quinolines or the boron center.

Nitrogen-rich conjugated microporous polymers: impact of building blocks on porosity and gas adsorption
A series of nitrogen-rich conjugated microporous polymers has been designed and synthesized. The polymers produced from the rigid building block show an increased specific surface area up to 1146 m 2 g −1 with a remarkable CO 2 uptake of 3.72 mmol g −1 at 1.13 bar and 273 K.
Tuning thermal contact conductance at graphene–copper interface via surface nanoengineering
Due to rapidly increasing power densities in nanoelectronics, efficient heat removal has become one of the most critical issues in thermal management and nanocircuit design. In this study, we report a surface nanoengineering design that can reduce the interfacial thermal resistance between graphene and copper substrat…
Nano- and micro-sized rare-earth carbonates and their use as precursors and sacrificial templates for the synthesis of new innovative materials
This review focuses on rare-earth carbonate materials of nano- and micro-size. It discusses in depth the different types of rare-earth carbonate compounds, diverse synthetic approaches and possibilities for chemical tuning of the size, shape and morphology. The interesting luminescence properties of lanthanide doped r…
Field-induced slow magnetic relaxation of octahedrally coordinated mononuclear Fe( iii )-, Co( ii )-, and Mn( iii )-containing polyoxometalates
Herein, we report for the first time polyoxometalate (POM)-based single-molecule magnets with mononuclear transition metal cores. The mononuclear Fe(III)-, Co(II)-, and Mn(III)-containing POMs have successfully been synthesized from a trivacant lacunary Keggin-type silicotungstate precursor TBA4H6[A-α-SiW9O34]·2H2O (T…

Surface bioengineering of diatomite based nanovectors for efficient intracellular uptake and drug delivery
Diatomite is a natural porous silica material of sedimentary origin. Due to its peculiar properties, it can be considered as a valid surrogate of synthetic porous silica for nano-based drug delivery. In this work, we exploit the potential of diatomite nanoparticles (DNPs) for drug delivery with the aim of developing a…

Platinum nanoparticles/graphene-oxide hybrid with excellent peroxidase-like activity and its application for cysteine detection
A facile approach is proposed for the growth of platinum nanoparticles on graphene oxide (PtNPs/GO). The resulting PtNPs/GO hybrid has been proved to function as peroxidase mimics that can catalyze the oxidation of peroxidase substrates in the presence of hydrogen peroxide (H2O2). Kinetic studies indicate that the PtN…
Plasmonic multi-shell nanomatryoshka particles as highly tunable SERS tags with built-in reporters
Here we report on the synthesis and averaged SERS measurements of multi-shell nanomatryoshka SERS tags. By tuning the number of shells or by changing the Raman reporters in different gap layers, their Raman intensities and spectral bands were tunable. These tags show great potential for SERS-based biosensing and bioim…

Potential of PVA-doped bacterial nano-cellulose tubular composites for artificial blood vessels
Bacterial nano-cellulose (BNC) hydrogel has been suggested as a promising biomaterial for artificial blood vessels. However, some properties of BNC do not achieve all of the requirements of a native blood vessel - compliance, for instance. In order to improve the properties of BNC tubes, poly(vinyl alcohol) (PVA) was…
