Nuclear Quadrupolar Resonance Structural Characterization of Halide Perovskites and Perovskitoids: A Roadmap from Electronic Structure Calculations for Lead-Iodide-Based Compounds.

Metal halide perovskites, including some of their related perovskitoid structures, form a semiconductor class of their own, which is arousing ever-growing interest from the scientific community. With halides being involved in the various structural arrangements, namely, pure corner-sharing MX (M is metal and X is halide) octahedra, for perovskite networks, or alternatively a combination of corner-, edge-, and/or face-sharing for related perovskitoids, they represent the ideal probe for characterizing the way octahedra are linked together. Well known for their inherently large quadrupolar constants, which is detrimental to the resolution of nuclear magnetic resonance spectroscopy, most abundant halide isotopes (Cl, Br, I) are in turn attractive for magnetic field-free nuclear quadrupolar resonance (NQR) spectroscopy.

Development and structural comparison of alkaline and organosolv coconut husks lignin as an eco-friendly lignin-phenol-glyoxal (LPG) wood adhesives.

The development of eco-friendly wood adhesives have gained more interest among adhesives industries due to the concerns about using carcinogenic formaldehyde and petroleum-based phenol in commercially available adhesives. Therefore, many studies have been done by using lignin to partially replace phenol and completely substitute formaldehyde with non-toxic glyoxal in a wood adhesive formulation. This study focused on using different percentages of lignin substitution (10 %, 30 % and 50 wt%) of alkaline and organosolv coconut husk lignin into soda lignin-phenol-glyoxal (SLPG), Kraft lignin-phenol-glyoxal (KLPG) and organosolv lignin-phenol-glyoxal (OLPG) adhesives.

Health check-up of a freshwater bivalve exposed to lithium.

Lithium (Li) has become essential for energy and digital transitions, especially as a component of rechargeable batteries. Its growing uses worldwide lead to increasing anthropogenic releases of Li into the environment, which is making Li as an emerging contaminant. It is thus critical to evaluate the ecotoxicological impact of Li, which has been poorly studied unlike its human toxicology.

Hierarchical Porous FeC@Fe-N-C Catalysts from Tannin-Fe(III) Complexes for Efficient Oxygen Reduction.

The rational design of metal-nitrogen-doped carbons (M-N-C) from available and cost-effective sources featuring high electrocatalytic performance and stability is attractive for the development of viable low-temperature fuel cells. Herein, mimosa tannin, an abundant polyphenol easily extracted from the Mimosa plant, is used as a natural carbon source to produce a tannin-Fe(III) coordination complex. This process is assisted by Pluronic F127, which acts as both a surfactant and a promoter of Fe-N active sites.

Frontoparietal asymmetries leading to conscious perception.

Recent human intracerebral recordings reveal that frontoparietal circuits linked by the superior longitudinal fasciculus (SLF) have critical, hemisphere-asymmetric contributions to conscious perception. Right-hemisphere networks are crucial for attention-based prioritization of information; left-hemisphere regions contribute to perceptual decisions and model building. These asymmetries confirm and specify clinical evidence from neglect patients.
