“…Literature shows that the mechanical analysis on spinal implants could be tested with a compressive load varying from 400N to 1000N [17][18][19]. Therefore, compressive load values from 600N [20][21] to a maximum of 1.5KN were given to test for any displacement or deformation of the design. The force was applied perpendicular to the direction of the implant.…”

Spinal implants are commonly used in the treatment of spinal disorders and injuries. Spine surgery for interbody fusion using intervertebral cages has become a prescribed method to treat degenerative disc disease and spondylolisthesis. Interbody fusion cages restore disc height by replacing the degenerated disc. Cage design, the material and the surgical approach play significant roles in a successful clinical outcome. A cage implant provides stability for functional spinal units; however, this is accomplished with rods and plates that require additional penetration and space in vertebrae. Hence, stand-alone cage devices are being used, but the designs and their effectiveness are still investigational. This work aims at designing intervertebral cage models with a self-locking mechanism. Four prospective designs for the locking mechanism are proposed. The design is modeled using SOLIDWORKS®. The mechanical analysis was performed on the modeled implants using ANSYS. The material of the implant is titanium, based on its proven biomechanical properties. The dimensions of the cage implant were chosen to best suit the lumbar L4/5 Intervertebral Disc (IVD). Analysis of results indicates that the proposed designs with the locking mechanism withstand load and provide stability to functional spinal units. The modeled cage implants with the proposed locking mechanism show prospective results from mechanical analysis and proceed further for biomechanical testing.

“…The broad applicability of nanoscale NiO relies on the material's high surface area and interesting properties, including chemical, electrochemical, and catalytic properties, which are not present in the bulk material. To meet the high demand for this nanoscale material, several synthetic methods have been developed based on hydrothermal,,,, sol‐gel,,, hot‐injection, co‐precipitation, microwave,, reverse micelle templated, electrochemical and pulsed laser ablation techniques, as well as techniques based on complex formation with an organic moieties and successively their thermal decomposition . Among the mentioned methods, the latest one is well known as scalable with high yield.…”

Influence of Pamoic Acid as a Complexing Agent in the Thermal Preparation of NiO Nanoparticles: Application to Electrochemical Water Oxidation

We developed a thermal decomposition method for preparing NiO nanoparticles (NiONPs) using disodium salt of pamoic acid (Na2PA) as a complexing agent and Ni(NO3)2⋅6H2O as a nickel precursor. Prior to thermal decomposition, Ni(NO3)2⋅6H2O was mixed with Na2PA in ethanol, and the ethanol was evaporated succesively. The dried reaction mass was characterized using Fourier transform infrared spectroscopy, X‐ray photoelectron spectroscopy, and thermal gravimetric analysis. Thermal decomposition was then performed in air to obtain the NiONPs. The role of Na2PA in the synthesis of NiONP was evaluated by preparing NiONPs according to the protocol described above without the addition of Na2PA. The X‐ray diffraction data indicated that crystalline NiO (bunsenite, cubic crystal system) formed with or without Na2PA; however, field emission scanning electron microscopy images showed that smaller monodisperse NiONPs formed only with the addition of Na2PA. Without Na2PA, the obtained NPs were quite large and polydisperse. The sizes of the NiONPs prepared in the presence of Na2PA were determined using transmission electron microscopy imaging to be 19.1 ± 3.2 nm. The electrocatalytic activity of the NiONPs toward water oxidation under alkaline conditions was evaluated by immobilizing the NPs onto an in‐house prepared filter paper derived carbon electrode, and compared.
