Editorial for the special issue of "Small Structures"

Depiction of sinusoidal displacement in nanocrystal superlattices through a minimum of geometric shapes and contrasting colors. This cover pays homage to the Bauhaus movement, celebrating human-made craftsmanship, clarity, and accessibility in scientific design, and remains faithful to its fundamental principle: less is more.

2023 JCP Emerging Investigators Special Collection: Tuning perovskite nanocrystal superlattices for superradiance in the presence of disorder

Oligodendrocyte precursor cells (OPCs) display functional plasticity beyond myelination. Kuwata et al. explore how hypoxia shapes OPC features after ischemic stroke. Combining single-cell transcriptomics with in vivo and ex vivo models, they reveal oxygen-dependent OPC phenotypes promoting angiogenesis and remyelination, highlighting OPC versatility and potential for novel stroke cell therapies.

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

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

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

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

Nocturnal lepidopteran pollinators face pesticide exposure risks in agricultural landscapes, yet lack adequate risk assessment frameworks compared to diurnal species. We present a formal model description for Noctua pronuba within the Animal Landscape and Man Simulation System (ALMaSS), providing the first comprehensive agent-based framework for assessing the impacts of pesticides on nocturnal mot

Supercrystals of lead-halide perovskite nanocrystals combine the semiconducting properties of bulk perovskites with quantum confinement effects and extend them to the macroscopic scale. Supercrystals assembled via a two-layer phase diffusion process using an acetonitrile antisolvent were recently shown to be unusually robust. We investigate how the acetonitrile-assisted self-assembly process influ

Infective endocarditis (IE) is most often caused by alpha-hemolytic streptococci or Staphylococcus aureus and is characterized by the presence of vegetations on the heart valves. Here we present a case of IE caused by Streptococcus pyogenes, a distinctly uncommon IE-pathogen, where no vegetations could be visualized on repeated echocardiography. Diagnosis was instead evident from septic embolizati

Aim: To model the long-term cost-effectiveness of scaling up two prevention interventions against type 2 diabetes mellitus (T2DM), i.e. community mobilisation through participatory learning and action (PLA) and mHealth mobile phone messaging, implemented in rural Bangladesh as part of the “DMagic” trial. Methods: A health-economic Markov model of the three-arm, cluster-randomised controlled DMagic

Introduction: Vaginal Natural Orifice Transluminal Endoscopic Surgery (vNOTES) is a technique combining vaginal entrance to the abdomen with endoscopic overview. Previous studies have shown that vNOTES decreases operating time, hospitalization, postoperative complications, and pain. We aimed to present patient demographics, costs, and surgical outcomes following the implementation of vNOTES for be

The transition toward sustainable energy systems has motivated extensive research into scalable routes for solar fuel generation. Silicon-based photoelectrodes are particularly promising due to their favorable optoelectronic properties, abundance, and compatibility with established microfabrication techniques. Nano-microstructuring silicon can enhance photoelectrochemical performance by improving

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

OBJECTIVES: This study investigates the expansion of CAR T-cells and its association to treatment outcome.METHODS: Patients with aggressive B-cell lymphomas treated with anti-CD19 CAR T-cell therapy axicabtagene ciloleucel (axi-cel) at Skåne and Sahlgrenska University Hospitals from 2019 to October 2024 were included. CAR T-cells in peripheral blood were measured by flow cytometry. Association bet
