“…The pollution of water sources caused by heavy metal ions, inorganic substances, organic matters, and bacteria from different agricultural, industrial, and medical waste sources has seriously affected people's lives and the ecosystems and organisms in the aquatic environment [1][2][3]. Determining the concentration of pollutants is an important step in environmental monitoring and supervision and is a basis for offering solutions to protect the environment.…”

A metal-organic framework MIL-53(Fe) was successfully synthesized by a simple hydrothermal method. A synthesized MIL-53(Fe) sample was characterized, and results indicated that the formed MIL-53(Fe) was a single phase with small particle size of 0.8 μm and homogeneous particle size distribution was obtained. The synthesized MIL-53(Fe) has been used to modify a glassy carbon electrode (GCE) by a drop-casting technique. Cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS) measurements of the MIL-53(Fe)-modified GCE showed that the MIL-53(Fe) was successfully immobilized onto the GCE electrode surface and the electrochemical behavior of the GCE/MIL-53(Fe) electrode was stable. In addition, several electrochemical parameters of MIL-53(Fe)-modified GCE (GCE/MIL-53(Fe)) including the heterogeneous standard rate constant ( k 0 ) and the electrochemically effective surface area ( A ) were calculated. Obtained results demonstrated that the synthesized MIL-53(Fe) with the small particle size, highly homogeneous particle size, and high electrochemically effective surface area was able to significantly enhance the electrochemical response signal of the working electrode. Therefore, the GCE/MIL-53(Fe) electrode has been used as a highly sensitive electrochemical sensor for cadmium ion (Cd(II)) monitoring in aqueous solution using differential pulse voltammetry (DPV) technique. The response signal of the electrochemical sensor increased linearly in the Cd(II) ion concentration range from 150 nM to 450 nM with the limit of detection (LOD) of 16 nM.

“…[18] Since the CNTs containing cobalt grew on the surface of the BNNSs, the peak at 670 cm −1 corresponded to the vibrational mode of CoN bond. [19] As explain that CNTs grew through covalent bonding into BNNS, the chemical environment of the C and N element in BN/ZIF and BN/ZC were investigated via XPS. The C 1s in BN/ZIF were deconvoluted into four chemical environments corresponding for CC (284.8 eV), CC (284.0 eV), CN (286.2 eV), and CN (285.5 eV) group of ZIF-67 ( Figure 2c.…”

The development of thermal conduction polymer‐based composites is important to solve the heat dissipation of electronic instruments under overheating conditions. The construction of thermal conductive pathways in composites and the reduction of contact resistance between fillers are crucial for concerning excellent thermal conduction properties. Herein, the oriented coherent thermal conductive network in composites is successfully developed via the in situ growth of carbon nanotubes (CNTs) into boron nitride nanosheets (BNNSs) skeleton prepared from ice‐templated. The thermal conductivity of composites reaches 3.21 W m−1 K−1 approximately low filler loading of 9.86 vol%, due to the formation of the covalent bonding between CNTs and BNNSs as reducing the thermal contact resistance by one order of magnitude. More importantly, non‐equilibrium molecular dynamics (NEMD) simulations are carried out to demonstrate the influence of CNTs in elevating the heat conductivity between BNNSs. Meanwhile, the volume resistivity of composites up to 1015 Ω cm far met the requirement of electrical insulation. This study provided a valuable idea for the design of thermal management materials for potential applications in integrated circuits.

“…Traditional analytical techniques for Hg 2+ detection, like spectrophotometry, atomic absorption spectroscopy, atomic fluorescence spectroscopy, x-ray absorption spectroscopy, and inductively coupled plasma mass spectrometry cannot achieve real-time and in situ monitoring at the expense of time-consuming inspection processes, complex sample pretreatment and destruction of biological samples [33][34][35][36][37][38][39]. Fluorescence probe technology has good selectivity, high sensitivity, fast response speed and the capability of real-time online detection, thus it has been widely applied for the detection of ions, molecules as well as other species [40][41][42][43][44][45][46].…”
