This study investigated the influence of Ni doping and thermal treatment (600, 800 degrees and 1000 degrees C) on the physiochemical properties of a commercially available low cost KA100 TiO2. Ni containing KA100 samples were prepared with different loading of Ni (3%, 6% and 9% wt to KA100) and subjected to heat treatement at 600 degrees, 800 degrees and 1000 degrees C. The as-prepared samples were characterized by X-ray diffraction (XRD), Scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS), Diffuse reflection UV-Visible spectroscopy and Raman spectroscopy and nitrogen-adsorption-desorption measurements to observe the nanophase changes in the particle characteristics following Ni modification and thermal treatment. The results show that the Ni atom entered the TiO2 lattice structure upon heat treatment at 800 degrees C and 1000 degrees C influencing the anatase-rutile phase transformation. The TiO2 powders after heat treatment had a bimodal pore-size distribution as the temperature of the heat treatment increased. In addition, the anatase crystallite size and average pore sizes increased. Photodegradation of NO(x) was investigated using the Ni doped KA100 as a photocatalyst. Modification of KA100 with nickel and heat treatment up to 1000 degrees C enhanced the photocatalysis for the degradation of NO(x). Typically, KA100 modified with 6% Ni and heat treated to 1000 degrees C exhibited excellent NO(x) removal activity.

Correlation of Increased Lateral Tibial Slope With Baseline Tibial Position in Intact Knees and Side-to-Side Anterior Tibial Translation for Knees With ACL Tears.

Background: Anterior cruciate ligament (ACL) stress techniques-including single-leg stress radiographs, Telos, and KT-1000 arthrometer-are highly accessible and can provide additional diagnostic information to assess ACL and ACL graft integrity. The degree of anterior tibial translation (ATT) may be useful in guiding treatment when a diagnosis on magnetic resonance imaging is not conclusive or for judging if additional treatments, such as anterolateral complex augmentation, may be necessary.
Purpose/hypothesis: The purpose of this study was to evaluate the effect of increasing posterior tibial slope (PTS) on baseline tibial position (BTP) and side-to-side differences (SSD) in ATT.

Manganese (Mn) is an essential element for plant growth but can be toxic at high levels. Pecan (Carya illinoensis), an important nut-producing species, has been observed to exhibit tolerance to high Mn levels. In this study, pecan seedlings were exposed to a nutrient solution containing either 2 μM (control) or 1000 μM (excess) MnSO to investigate the physiological mechanisms.

We report the reversible addition-fragmentation chain transfer (RAFT) dispersion polymerization of 2-hydroxyethyl methacrylate (HEMA) in -dodecane using a poly(lauryl methacrylate) (PLMA) precursor at 90 °C. This formulation is an example of polymerization-induced self-assembly (PISA), which leads to the formation of a colloidal dispersion of spherical PLMA-PHEMA nanoparticles at 10-20% w/w solids. PISA syntheses involving polar monomers in non-polar media have been previously reported but this particular system offers some unexpected and interesting challenges in terms of both synthesis and characterization.

Since the World Health Organization declared COVID-19 no longer a public health emergency in 2023, over a year has passed. However, there has been insufficient research into whether the physical health of adolescents has recovered post-Pandemic. The COVID-19 Pandemic profoundly impacted the lives and health of adolescents globally, with prolonged lockdowns and social isolation measures potentially causing adverse effects on their physical health.
