Deep Eutectic Solvent (DES) for In Situ Templating Carbon Material: Carbon Characterization and Application in Supercapacitors Containing Multivalent Ions
(MDPI, 2022)
The development of carbon materials with desirable textures and new aqueous electrolytes is the key strategy to improve the performance of supercapacitors. Herein, a deep eutectic solvent (DES) was used for in situ templating ...
Bio-Inspired Nanomembranes as Building Blocks for Nanophotonics, Plasmonics and Metamaterials
(MDPI AG, 2022)
Nanomembranes are the most widespread building block of life, as they encompass cell and organelle walls. Their synthetic counterparts can be described as freestanding or free-floating structures thinner than 100 nm, down ...
Spontaneous Symmetry Breaking: The Case of Crazy Clock and Beyond
(MDPI AG, 2022)
In this work, we describe the crazy-clock phenomenon involving the state I (low iodide and iodine concentration) to state II (high iodide and iodine concentration with new iodine phase) transition after a Briggs–Rauscher ...
Investigation of Nonlinear Piezoelectric Energy Harvester for Low-Frequency and Wideband Applications
(MDPI AG, 2022)
This paper proposes a monostable nonlinear Piezoelectric Energy Harvester (PEH). The harvester is based on an unconventional exsect-tapered fixed-guided spring design, which introduces nonlinearity into the system due to ...
Characterization, axial anisotropy and formation conditions of celestine from the Jabal Eghei (Nuqay) late Neogene – Pleistocene volcanic province, southern Libya: Constraints on the mineralogical geothermometer
(Cambridge University Press, 2024)
Five celestine crystals are sampled from the (paleo)surface intervening between the late Miocene to Pleistocene basaltic sequences of the Jabal Eghei(Nuqay) volcanic province (southern Libya). The celestine specimens are ...
Concentration and mobility of trace elements (Li, Ba, Sr, Ag, Hg, B) and macronutrients (Ca, Mg, K) in soil-orchid system on different bedrock types
(Springer, 2022)
The mobility of chemical elements in the soil-orchid system has been poorly studied. The aim of this study is to evaluate the uptake and mobility of several trace (Li, Ba, Sr, Ag, Hg, and B) and macronutrients (Ca, Mg, and ...
A Core-Shell Amino-Functionalized Magnetic Molecularly Imprinted Polymer Based on Glycidyl Methacrylate for Dispersive Solid-Phase Microextraction of Aniline
(Switzerland : Multidisciplinary Digital Publishing Institute (MDPI), 2022)
A core-shell amino-functionalized glycidyl methacrylate magnetic molecularly imprinted polymer (MIP) was synthesized by the suspension polymerization/surface imprinting method and characterized by Fourier transform infrared ...
Thermodynamic Properties of Caffeine in Ethylene Glycol at High Pressures and High Temperatures
(USA : American Chemical Society, 2022)
Ethylene glycol is recognized as a heat transfer fluid. To improve its performance, caffeine is added to pure ethylene glycol. The experimental measurements of densities at pressures of up to 60 MPa and in the range of ...
Structural changes of waste biomass induced by alkaline treatment: the effect on crystallinity and thermal properties
(Springer Science and Business Media LLC, 2020)
A low-cost waste biomass generated from a food industry, apricot shells, was subjected to alkali modification in order to compare morphology, crystalline structure and thermal stability of native and modified biomass, ...
Removal of methyl orange using combined ZnO/Fe2O3/ZnO-Zn composite coated to the aluminium foil in the presence of simulated solar radiation
(Switzerland : Springer Nature, 2022)
In this paper, the optimal preparative conditions (current density, deposition temperature, calcination temperature) for the original electrochemical synthesis of ZnO-Zn coating on aluminum foil support (ZnAF) were examined ...
