Summary: This study explored europium-doped carbonated apatites for the first time and determined the location of carbonate using an environment model for the analysis of IR and NMR spectra. Europium-doped carbonated apatites with Eu/(Eu + Ca) mole ratios of about 10% were synthesized using aqueous one-step and addition methods. The IR and NMR spectra of carbonate in the samples were described using the environment model, and it was found that A-type carbonate is assigned to channels containing only calcium ions or channels containing one Na+ or a vacancy. The presence of Eu3+ channel and the use of triammonium phosphate in the synthesis resulted in considerable A-type carbonate. The distribution of carbonate in the apatites studied was approximately 60:40 for channel occupancy versus replacement of phosphate. It was proposed that europium replaces calcium ions in the Ca(II) (channel) location, and the stoichiometry of the products suggests that the charge-balance mechanism likely involves the substitution of two europium ions for three calcium ions with the formation of a calcium vacancy. The environment model was also used to correlate the a-axis lattice parameter with the percent A-type carbonate.

Summary: The study explores the environment model for predicting the location of carbonate ions in apatites, revealing the influence of different substituents on the ion's position. It concludes that first-row transition metal ions have little effect on the location of the carbonate ion in apatites.

Summary: Magnetic resonance imaging was used to study the gravity sedimentation of kaolin suspensions for the first time. The results showed complex behaviors dependent on the initial kaolin concentration and solution pH, including various types of channels and voids. The discovery of spontaneous voids during kaolin sedimentation may provide an explanation for the formation of water channels.

Summary: Single-crystal Ni-rich cathodes face issues such as performance degradation and structural instability during cycling. Despite the benefits of using single-crystal Ni-rich cathodes, ion diffusion limitations in large single-crystal particles impact rate capability. The application of an in situ Li1.4Y0.4Ti1.6(PO4)(3) conductive network helps improve lithium-ion transport and cycling life in high-nickel content cathodes.

Summary: This study used the Hubble Space Telescope to observe the evolution of the DART impact ejecta from 15 minutes to 18.5 days, revealing that the ejecta initially are dominated by gravitational interaction and later driven by solar radiation pressure, forming a sustained tail consistent with previously observed asteroid tails. This provides a framework for understanding the fundamental mechanisms of asteroids disrupted by impacts.

Summary: Coal mining activities release compounds that can cause oxidative damage to DNA. We compared blood samples from 150 individuals exposed to coal mining residues and 120 non-exposed individuals, finding higher concentrations of certain elements and hypokalemia in the exposed group. The enzyme-modified comet assay suggests that coal mining residues cause oxidative DNA damage, especially to purines. Understanding the effects of these inorganic elements on DNA damage and oxidative stress pathways is crucial for understanding the impact of coal mining residues on human health.

Summary: This study demonstrates the possibility of obtaining colloidal all-inorganic gold nanocrystals directly from magic-size clusters with the assistance of inorganic molecules. The use of simple inorganic ligands allows for the tuning of the surface state and modification with different functional groups. Negatively charged all-inorganic gold nanocrystals exhibit improved efficiency and current density in the reduction of CO2.

Summary: Monoclonal antibody therapeutics often contain polysorbate for stabilizing effects, but this may lead to particle formation. The presence of human serum albumin can prevent and dissolve fatty acid particles, providing a plausible explanation for previous observations and reducing concerns about particle levels in the final drug product.

Summary: The Winter Fog Experiment (WiFEX) was conducted at Indira Gandhi International Airport in Delhi, India, during the winter of 2017-2018 to study ammonia (NH3) and its derivatives. High-temporal-resolution simulation of NH3 using the WRF-Chem model and measurements from the MARGA instrument were compared. The simulation showed higher NH3 concentrations and lower NH4+ concentrations than the measurements, but adding HCl/Cl- chemistry improved the agreement between the simulation and measurements.
