In this paper we focus on the preparation of the epoxy resin Epikote 828LVEL reinforced with nanosilica. Epoxy composites containing 130-nm spherical silica nanoparticles were prepared at a fixed volume fraction ([phi] = 0.5 %). To prevent agglomeration the silica fillers were initially pre-treated ...

HER active sites;multivariate statistical analysis;nickel catalysts;ToF-SIMS;
Unambiguous identification of active sites in heterogeneous catalysis remains a major challenge, particularly formaterials with ultrathin, chemically mixed surface layers. Here, we demonstrate a generalizable approach that combinestime-of-flight secondary ion mass spectrometry (ToF-SIMS) with multivar ...

In this paper we discuss the mechanical and thermal properties of shape-memory polymer composites (SMPCs) filled with SiO2 nanoparticles. A series of SMPC samples was prepared using a commercially provided shape-memory polymer (SMP) filled with different mass fractions of 600-nm and 130-nm SiO2 part ...

Lithium-ion batteries (LIBs) are central to the urgent societal need to decarbonize both transportation and energy storage on the grid. Unfortunately, despite their attractive energy/power density, as well as high coulombic and energy efficiencies, further improvement of this technology – especially ...

Iridium based particles as the most promising proton exchange membrane electrolyser electrocatalysts were investigated
by transmission electron microscopy (TEM), and by coupling of electrochemical flow cell (EFC) with online inductively
coupled plasma mass spectrometer (ICP-MS). Additionally, a th ...

Understanding material transformations at the nano- and microscale is essential for advancing electrocatalysis, energy storage, and other applications. Conventional SEM imaging, which captures random locations before and after treatment, struggles to distinguish real transformations from inherent sa ...

Compared to aqueous electrolytes, fundamental understanding of the chemical and electrochemical processes occurring in non-aqueous electrolytes is far less developed. This is no different for Li-ion battery (LiB) electrolytes, where many questions regarding the solid-electrolyte interphase (SEI) on ...

Približno 46 % vseh svetovnih emisij Hg je posledica izgorevanja fosilnih goriv v namene pridobivanja električne in toplotne energije. Zaradi visokih koncentracij onesnaževala v dimnih plinih si strokovnjaki prizadevajo razviti ustrezno tehnologijo, ki bi omejila izpuste Hg že na viru. Tako bi se iz ...
