Carbon Black (CB), graphene, and nanodiamond are distinct carbonaceous insoluble nanoparticles. Reactive Oxygen Species (ROS) associated with these particles play a significant role in both in vivo and in vitro toxicity evaluations. Accurate assessment of ROS activity is relevant for toxicity screening and in ensuring safe working environments as well as guiding the innovation by safe-and-sustaina
Aducanumab, a human IgG1 antibody with plaque-clearing effects and modest clinical benefit, binds selectively to aggregated Aβ via the N-terminal region. Yet, the molecular details of how the antibody engages Aβ1-42 fibrils remain unresolved. Using magic-angle spinning NMR, we show that binding of aducanumab preserves the overall architecture of the Aβ1-42 fibril core while inducing significant st
Background: Air pollution is a known risk factor for chronic respiratory diseases, including asthma and chronic obstructive pulmonary disease (COPD). However, evidence regarding the role of black carbon (BC) remains mixed and sparse. This study aimed to examine the association of long-term exposure to air pollution, focusing on BC, with incident asthma and COPD in adults. Method: We followed 28,73
Photocatalysis has emerged as a promising technology for environmental remediation and sustainable energy production. This chapter provides a brief overview of the main definitions and recent advancements in photocatalysis using metal nanoparticles supported on metal oxides. The chapter also explores the photocatalytic mechanisms, highlighting the role of metal nanoparticles in providing alternati
The development of acid-stable, non-precious catalysts for the oxygen evolution reaction (OER) remains a critical challenge for proton exchange membrane water electrolyzers (PEMWEs). While Co3O4 shows promising OER activity, its rapid dissolution in acidic media severely limits practical application. Here, we design a self-adaptive protection strategy by depositing ZrN coatings on Co3O4 precursor
Lifetimes of photoexcited charge transfer (CT) states in transition metal chromophores are influenced by low-lying ligand field (LF) excited states, especially for 3d metal complexes. To manipulate interactions between LF and CT states, it is important to be able to control LF excited state energies using tunable synthetic variables. In this report, we use Fe 2p3d L3-edge resonant inelastic X-ray
The clustering of certain proteins into oligomers and fibrils, known as amyloids, underlies the pathology of diseases such as Alzheimer’s disease, Parkinson’s disease, and type 2 diabetes. These processes are counteracted by the cellular protein quality control system, which includes molecular chaperones that interact with disease-associated proteins. One such chaperone is DNAJB6b, which has gaine
While the multiexciton dynamics in semiconductor nanocrystals is widely explored, to determine the absorption cross sections for multiexcitons of varying order is still a challenge. In this study, we performed pump–repump–probe transient absorption (ppp-TA) spectroscopic measurements on CdSe@CdS nanorods to gain insights into the absorption cross sections for multiexcitons. By tuning the pump–repu
Spectroscopic studies of energy transport through the photosynthetic apparatus have been crucial to expanding our understanding of biological energy conversion. Correlating spectroscopic information to the electronic structure and function in these complex systems remains highly challenging, however. While cryogenic experimental conditions help in improving the effective spectral resolution and sa
The concept of quasicrystal approximants is best pursued with reference to the quasicrystals themselves. This makes the classification of approximants into classes congruent to those for quasicrystals useful, that is, axial and icosahedral. As noted by several authors, work on approximants has come full circle; the initial interest in approximants grew out of a desire to understand particularly th
Low back pain is common and negatively impacts quality of life and workplace productivity. However, few studies have focused on small- and medium-sized enterprises (SMEs) where risk factors are prevalent. This cross-sectional study examined the association and structural relationships between physical and social factors in low back pain among Japanese SME workers. We analyzed survey data collected

The activity and stability of an electrocatalyst is governed by the structural and chemical changes occurring at the solid–liquid interface. While single crystal electrodes have often served as model systems to elucidate structure–function relationships, extending these insights to more realistic polycrystalline electrodes requires experimental techniques with spatial resolution that can operate u
Using ultra-broadband transient terahertz (THz) spectroscopy, complemented by transient absorption (TA) and photoluminescence (PL) measurements, we directly track the generation and relaxation of photoexcited hot carriers, as well as the ultrafast formation of excitons in the transition metal phosphorus trichalcogenide NiPS3, with a temporal resolution of sub-100 fs. A subset of excitons exhibits
Hybrid perovskites have demonstrated exceptional versatility as optoelectronic materials since their introduction as light absorbers and charge transport media in photovoltaic devices. These materials are now utilized in photodetectors, photocatalysis, and light-emitting devices, offering emission capabilities spanning from the ultraviolet to the mid-infrared spectrum. Recent studies in the far-in
Direct catalytic conversion of methane to methanol offers a pathway for transforming a potent greenhouse gas into a portable clean liquid fuel, thereby mitigating carbon emissions and supporting sustainable energy. However, this process faces challenges from thermodynamically favorable methanol overoxidation. Here, we show that spatiotemporal regulation of photogenerated charge carriers on enginee
