Summary: The traditional belief about pore structure determining encapsulation ratio in substrate was challenged in this study, which demonstrated that surface adsorption also played a significant role. By encapsulating polyethylene glycol (PEG) within hydroxyapatite (HAP) and dickite substrates, it was found that HAP adsorbed PEG through the surface, affecting the direct impregnation process and leading to a calculated maximum encapsulation ratio close to the actual value.

Summary: Controlling the morphology and size of particles in processes like crystallization and precipitation is still a challenging task. This study presents a simple process of precipitation and controlled remodeling of hydroxyapatite nanoparticles into plate and rod-like morphologies. The results show that the temperature and pH changes during the remodeling step affect the properties of the resulting particles.

Summary: To obtain high spatial resolution testing results for a timely targeted public health response, the development of rapid, high-throughput, and sensitive virus concentration methods is urgently needed. In this study, a PEG precipitation-based three-step centrifugation method was developed, which can process over 100 samples per day and reach a process limit of detection (PLoD) of 3286 copies/L wastewater. The testing capacity can be further increased by shortening incubation and centrifugation time without significantly affecting the method sensitivity. This high-throughput, cost-effective, and sensitive tool will facilitate the establishment of nearly real-time wastewater surveillance networks for valuable public health information.

Summary: In this study, nanometric hydroxyapatite was synthesized by wet chemical precipitation using a calcium hydroxide precursor obtained from eggshells. The synthesized crystals exhibited irregular-spherical morphologies with a diameter ranging from 10 to 90 nm, and contained multiple elements similar to those found in mammalian bones. Commercial synthetic hydroxyapatite, on the other hand, formed micron-sized flakes clusters with only calcium and phosphorus ions present.

Summary: In this experimental work, the EPR signal intensity of hydroxyapatite (HAP) samples was studied from a dosimetric standpoint. HAP samples were prepared in different ways and irradiated with various absorbed doses. The EPR signal intensity of the samples was tested in air at room temperature, showing a linear relationship with dose up to 10 kGy. The findings highlight the importance of fabrication procedure, particle size, carbon impurity, and morphology in determining the EPR signal intensity, with a sample having a grain size of approximately 30 nm and a carbon impurity of 0.47% exhibiting the highest EPR signal intensity with dose.

Summary: Hydroxyapatite (HA) is an important component of artificial bone grafts, but its poor dispersibility and tendency to form aggregates pose challenges. Chemical bonding of biologically active molecules is suggested to modify the HA surface to prevent aggregation and achieve homogeneous dispersion. Irradiation is shown to produce bioactive and antibacterial nanosized hydroxyapatite (nHA) by inducing morphological variations and reactive oxygen species formation. Furthermore, small molecules such as proteins, peptides, drugs, and photocatalysts play a significant role in modifying the surface properties of nHA for stable and bioactive artificial bone implants.

Summary: Zinc oxide-cobalt oxide nanocomposites (ZnO-Co3O4 NCs) with different concentrations of Co2+ ions were synthesized and characterized. The presence of Co3O4 induced a red shift in the absorption spectra of ZnO-Co3O4 NCs and reduced their band gap energy. FESEM images revealed a composite nanostructure morphology of nanoparticles and nanorods in the ZnO-Co3O4 NCs.

Summary: Extensive research has revealed that oxygen evolution reaction (OER) in alkaline conditions involves dynamic surface restructuring. The development and design of sulfide/oxide pre-catalysts can reasonably adjust the composition and structure after surface reconstruction, which is crucial for OER. This study utilized a simple two-step hydrothermal method to achieve in situ S leaching and doping, inducing the composition change and structure reconstruction of CoFe oxides. The transformed FeOOH and CoOOH exhibited excellent OER activity and could be easily mass-produced using low-cost iron based materials and simple methods.

Summary: Zero-dimensional organic-inorganic metal halides (OMHs) are gaining attention in the fabrication of light-emitting diodes due to their broad emission band and high photoluminescence quantum yield. This work synthesized a zero-dimensional organic tetraphenylphosphonium bismuth chloride (TBC) that showed efficient blue light emission, with the emission mechanism attributed to the transition of Bi3+ ions. White light-emitting diodes (WLEDs) were fabricated using TBC, along with green-emitting and red-emitting single crystals, achieving single-component white emissions. These findings demonstrate the different emission mechanism of ns2 ions-based OMHs and highlight the potential of bismuth-based OMHs in WLEDs applications.

Summary: The revolutionary design concept of high-entropy alloys has brought new opportunities and challenges to the development of advanced metal materials. In this work, AlCrCuFe2NiTix high-entropy flux cored wires were prepared by combining the design idea of a high-entropy alloy with the characteristics of flux cored wire. AlCr-CuFe2NiTix high-entropy surfacing alloys were prepared using gas metal arc welding technology. The wear properties of the alloys were analyzed, and the phase composition, microstructure, strengthening mechanism, and wear mechanism were discussed. The results show that the alloys exhibit a dendritic microstructure with BCC/B2 + FCC phases. Increasing Ti content leads to the precipitation of Laves phase. The alloys show improved microhardness and wear resistance due to the precipitation of coherent B2 and Laves phases. However, excessive Ti addition results in the increase of Laves phase and reduced wear resistance of the alloys.

Summary: In this study, six bimetallic FeCo particles were synthesized via the hydrothermal method at different Fe:Co ratios. The Fe:Co ratio not only modulates the composition of the particles but also influences their structure and magnetic properties. The FeCo alloys showed a transformation from an Fe-based structure to a Co-based structure with increasing Co content. The Fe:Co ratio of 1:1 and 3:1 resulted in particles with the highest and lowest saturation magnetization, respectively.

Summary: We conducted a study on the formation of ultra-fine Y-Ti-Ta-O nano-oxides in Ta+B micro-alloyed 13CrWTi-ODS alloys using electron microscopy and first-principles calculations. The Y-Ti-Ta-O nano-oxides were found to be mainly Y2(Ti,Ta)2O7, with an average size of 7 nm and a number density of 6.8 x 1023 m-3. Excess boron was found to enhance the adhesion of some low-sigma grain boundaries but weaken the Fe/Y2Ti2O7 interface, while excess tantalum enhanced the Fe/Y2Ti2O7 interface but caused serious degradation of grain boundaries.

Summary: The structure and magnetism of cobalt ferrites after Mn2+-Tb3+ co-doping were studied. Co-doped samples exhibited cubic spinel structure and spherical shape of ferrite nanoparticles. The redistribution of Co2+ and Fe3+ ions between octahedral and tetrahedral sites was observed due to Mn2+-Tb3+ co-doping. The coercivity and magnetization saturation of co-doped samples were significantly improved, leading to a maximum energy product that is 190% higher than that of the un-doped sample.

Summary: Recently, there has been an increasing interest in developing ultra-fine nanostructured electrodes with extensive reaction areas to enhance the performance and low-temperature operation of solid oxide fuel cells. The use of a refined approach involving co-sputtering metal alloys and oxide targets has demonstrated the feasibility of nano-columnar structures in perovskite-based electrodes, expanding the temperature range of thin film electrodes. This study systematically examines the effects of chamber pressure control in the co-sputtering process and identifies the intricate relationship between sputtering pressure and film structure. By fine-tuning the columnar growth in the electrode, significant improvements in performance and thermo-mechanical properties were achieved, resulting in high-performance all-sputtered solid oxide fuel cells.
