Abstract A comprehensive nanoscale understanding of layered double hydroxide (LDH) thermal evolution is critical for their current and future applications as catalysts, flame retardants oxygen performers. In this report, we applied in situ transmission electron microscopy (TEM) to extensively characterise the progressions nickel-iron containing (Ni-Fe) LDH nanomaterials. The combinative approach TEM selected area diffraction (SAED) yielded both a morphological crystallographic such...
Abstract Very recently, it has been reported that mixed transition metal oxide (TMO)/MXene catalysts show improved performance over TMO only for the oxygen evolution reaction (OER). However, reasoning behind this observation is unknown. In work Co(OH) 2 /Ti 3 C T x were prepared and characterized OER using ex situ operando spectroscopy techniques in order to initiate understanding of why TMO/MXene materials better performances compared catalysts. This shows electrocatalysis composite...
This paper describes the wet-chemistry synthesis of highly crystalline hexagonal flakes Ni-Fe layered double hydroxide (LDH) produced at temperature as low 100 °C. The with diameter in range 0.5-1.5 μm and thickness between 15 20 nm were obtained by homogeneous precipitation method use triethanolamine (TEA) urea. By analyzing intermediate products, it is suggested that, differently from previous reports, a thermodynamically metastable iron oxyhydroxide Ni-TEA complex are firstly formed room...

In academic labs, most oxygen evolution reaction studies are carried out in conventional three-electrode cell set-ups; however, this configuration may not accurately represent conditions experienced under practical electrolyser conditions.
Nonviral vectors offer a safe alternative to viral for gene therapy applications, albeit typically exhibiting lower transfection efficiencies. As result, there remains significant need the development of nonviral delivery system with low cytotoxicity and high efficacy as tool transient delivery. This study assesses MgAl-NO3 layered double hydroxide (LDH) vector deliver nucleic acids (pDNA, miRNA siRNA) mesenchymal stromal cells (MSCs) in 2D culture using 3D tissue engineering scaffold...
Abstract Batteries are the most abundant form of electrochemical energy storage. Lithium and sodium ion batteries account for a significant portion battery market, but high-performance electrochemically active materials still need to be discovered optimized these technologies. Recently, tin(II) oxide (SnO) has emerged as highly promising electrode. In this work, we present facile synthesis method produce SnO microparticles whose size shape can tailored by changing solvent nature. We study...
Abstract Electron irradiation of Ni–Fe layered double hydroxides (LDHs) was investigated in the transmission electron microscope (TEM). The initial structure possessed a flat hexagonal morphology made up crystalline domains with well-defined crystal structure. LDHs were susceptible to significant structural decompositions during irradiation. generation pores and crystallographic breakdown LDH routinely occurred. In addition, compositional change established by energy loss spectroscopy...
Abstract Nickel–iron-layered double hydroxide (NiFe LDH) platelets with high morphological regularity and submicrometre lateral dimensions were synthesized using a homogeneous precipitation technique for highly efficient catalysis of the oxygen evolution reaction (OER). Considering edge sites are point activity, efforts made to control platelet size within dispersions. The goal is controllably isolate characterize size-reduced NiFe LDH particles. Synthetic approaches have not been...

The oxygen evolution reaction (OER) has drawn significant interest in the field of renewable and sustainable energy recent years, with potential applications for hybrid electric vehicles (HEV) form hydrogen fuel cells metal-air batteries, among others. Perhaps most feature OER is fact that it a necessary ‘step’ H 2 gas by water electrolysis, bringing an associated (E ≈ 1.23 V). To overcome this barrier minimum overpoetential (η), effective electrocatalyst required to facilitate reaction....
Currently, approximately 96% of global H 2 production is carried out by fossil fuel based routes such as steam reforming natural gas or coal gasification; 1 while only 4% generated renewable energy water splitting. To increase the percentage produced splitting, it necessary to lower overall cost and, at same time, improve efficiency associated with splitting technologies, which is, closely related cost, durability and kinetic issues arising from catalysts used. Water also known electrolysis,...
