Energiespeicher aus Papier: Papierbasierte, flexible Festkörpersuperkondensatoren wurden erzeugt, die mit einem piezoelektrischen Biegewandler oder einer Solarzelle geladen und durch Betreiben eines Spannungssensors blau emittierenden Diode entladen werden. Die Kondensatoren können in energieautarken Nanosystemen eingesetzt werden (siehe Bild). Detailed facts of importance to specialist readers are published as "Supporting Information". Such documents peer-reviewed, but not copy-edited or...
Chemical separation membranes, drug delivery agents, and other nascent applications of metal–organic frameworks (MOFs) benefit from preparing MOFs as nanoparticles (nanoMOFs) by controlling their particle surfaces. Despite the lack deliberately added surface ligands, or surfactants, common examples nanoMOFs exhibit multiweek colloidal stability in a range polar solvents. Whereas nanocrystal general arises combination electrostatic repulsion, steric hindrance between species, favorable...
MXenes, most commonly transition metal carbides, are a family of two-dimensional (2D) materials with promising potential in, among other applications, supercapacitors and batteries. MXenes synthesized by etching aluminum or gallium layers in its parent MAX phase directly HF situ formation using fluoride salt strong acid. A undesired byproduct MXene synthesis is AlF3·3H2O. To relieve from AlF3·3H2O impurity, it important to elucidate the factors that drive formation. Here, we dually deduce...

The Negev desert in Israel is home to large quantities of organic-rich, shallow marine sedimentary lithologies that could potentially accommodate the disposal spent nuclear fuel. Previous thermal analyses carbonates have focused on industrially relevant considerations such as natural gas and oil extraction or pyrolysis for recovering hydrocarbon fuels. This study addresses evolution organic-rich carbonate, siliceous, phosphorite rocks associated chemical, mineralogical, microstructural...
The LiOH-based cathode chemistry has demonstrated potential for high-energy Li-O2 batteries. However, the understanding of such complex remains incomplete. Herein, we use combined experimental methods with ab initio calculations to study LiOH chemistry. We provide a unified reaction mechanism formation during discharge via net 4 e- oxygen reduction, in which Li2 O2 acts as intermediate low water-content electrolyte but LiHO2 high electrolyte. Besides, decomposes 1 oxidation charge,...
High-order wave mixing in solid-state platforms gather increasing importance due to the development of advanced lasers and integrated photonic circuit for both classical quantum information. However, high-order is generally inefficient solids under weak pump. Here, we observed presence phase matching five-wave (5WM) propagating a zinc oxide (ZnO) microwire.

Defining the energetic landscape of pseudocapacitive materials such as transition metal layered double hydroxides (LDHs) upon redox-site enrichment is essential to harnessing their power for effective energy storage.

Moreover, higher specific capacity at an intermediate 3 enabled...
