Abstract Backgrounds Nickel-titanium (NiTi) rotary instruments are widely used in endodontics because of their flexibility and superelasticity. However, the cyclic fatigue resistance of ORODEKA and M3-L systems in curved...

ABSTRACT Electrooxidation of sterols is recognized as a promising approach for synthesizing value‐added steroid hormone pharmaceuticals. However, enhancing current density while delivering market‐required steroidal c...

In this study, thin nickel oxide nanomembranes were obtained using thermal chemical spraying technology, which involves spraying a green-colored chemical solution at a rate of 30 sprays onto glass substrates with an area...

Abstract Antibiotic residues in aquatic systems accelerate antimicrobial resistance and require efficient solar-driven advanced oxidation strategies. Herein, we engineer an oxygen-vacancy-rich La-doped NiFe₂O₄ spinel...

ABSTRACT For the spiro‐OMeTAD‐based hole‐transporting layer (HTL), despite its widespread implementation, the pragmatic deployment of perovskite solar cells remains profoundly constrained by multifaceted intrinsic ...

Context and Background: Rapid growth in Tanzania’s mining sector has intensified compulsory land acquisition (CLA), yet the practical integration of Environmental, Social, and Governance (ESG) principles into valuat...

Ultrathin ohmic contacts were fabricated on GaP(111) single crystals using argon ion (Ar⁺) implantation at an energy of E₀ = 2 keV and a dose of D = 2 × 10¹⁷ cm⁻², under high vacuum conditions (10⁻⁷ Pa). P...

Abstract This study evaluated spatiotemporal variations in drinking water quality, pollution levels, and heavy metal contamination in key rural water sources including, 23 dams, eight minor lakes, and three swamps. A tot...

The study deals with determining the concentrations of heavy metals—silver (Ag), aluminum (Al), arsenic (As), barium (Ba), cadmium (Cd), cobalt (Co), chromium (Cr), copper (Cu), iron (Fe), lithium (Li), manganese (Mn),...

High-T_{c} superconductivity has recently been discovered in Ruddlesden-Popper (RP)-phase nickelates under pressure, where the low-energy electronic structure is dominated by Ni d_{x^{2}−y^{2}} and d_{z^{2}} orbitals. ...

Royal jelly is a unique product of worker bees, namely the secret of their pharyngeal and maxillary glands. It is the main source of nutrients and biologically active substances for larvae and queens. Royal jelly include...

To enhance the total output energy and power of energetic materials, plasma that generated by electrically exploded metal wires was employed to initiate the detonation of energetic materials, thereby achieving the couple...

Abstract Objective To evaluate the effect of gradually increasing orthodontic force magnitude compared with a constant force magnitude on the rate of tooth movement during maxillary canine retraction. Methods This split-...

Abstract In polymer electrolyte fuel cells (PEFCs), temperature gradients can exert a substantial influence on cell performance and durability. Monitoring these gradients without perturbing fuel cell operation is one of ...

Abstract Naturally, neonates as well as infants in the society are the most susceptible health effects of malnutrition and heavy metal risks due to their inevitable rapid development of their organs and tissues for prope...

Abstract This study applies a stochastic framework to quantify Potentially Toxic Elements (PTEs) and related risks in soils of the Maluwe–Tinga–Wasipe corridor in the Savannah Region of Ghana. A total of 729 B-horizo...

Abstract: To investigate the interaction of heterogeneous solutes in the common molten pool flow during laser welding of heat-resistant steel and nickel-based alloy, a multiphase flow coupled welding model was establishe...

In this study nickel (Ni) and iron (Fe) co-deposition was performed on Al to produce Al@Ni-Fe core-shell energetic powders using electroless deposition. Energy released from Al@Ni-Fe powders in oxidizing environment was ...

Abstract In this study, we examined how substrate temperature affects the structural, morphological, electronic, and magnetic properties of nickel ferrite (NiFe2O4) thin films synthesized via spray pyrolysis. We investig...

Ureases are nickel-dependent enzymes widely distributed in nature that play fundamental roles in both healthcare and agriculture by catalyzing the hydrolysis of urea into ammonia and carbon dioxide. This enzymatic activi...

Background: Methamphetamine (meth) is an addictive stimulant that increases risk of trauma and infections. Global meth use continues to rise and the economic impact of meth use on the orthopedic trauma system is poorly u...
