Circularly polarized luminescence (CPL) with tunable chirality is currently a challenging issue in the development of supramolecular nanomaterials. We herein report the formation of helical nanoribbons which grow into helical tubes through dynamic helicity inversion. For this, chiral Pt II complexes of terpyridine derivatives, namely S - trans - 1 and R - trans - 1 , with respective S - and R -alanine subunits and incorporating trans -double bonds in the alkyl chain were prepared. In DMSO/H 2 O (5 : 1 v / v ), S - trans - 1 initially forms a fibrous self-assembled product, which then undergoes dynamic transformation into helical tubes (left-handed or M -type) through helical ribbons (right-handed or P -type). Interestingly, both helical supramolecular architectures are capable of emitting CPL signals. The metastable helical ribbons show CPL signals ( g lum =±4.7×10 −2 ) at 570 nm. Meanwhile, the nanotubes, which are the thermodynamic products, show intense CPL signals ( g lum =±5.6×10 −2 ) at 610 nm accompanied by helicity inversion. This study provides an efficient way to develop highly dissymmetric CPL nanomaterials by regulating the morphology of metallosupramolecular architectures.

Nickel doped magnesium cubic spinel ferrite nanoparticles (NPs) were prepared through microwave combustion method (MCM). The structure of magnesium ferrite normal spinel is obtained from XRD analysis. The average crystallite size is between 26 and 17 nm. The elemental compositions and oxidizing states of Ni2+ doped MgFe2O4 ferrites were evaluated by using XPS analysis. Morphology of spinel nanoparticles were studied using HR-SEM images. The energy dispersive X-ray method is used for ensuring the presence of elements and the band gap value 2.09, 2.02, 1.85 and 1.82 eV have obtained using the tau’c relation. The magnesium spinel structure is confirmed the band at 434 and 561 cm-1 which corresponds to the stretching vibration of octahedral site (Mg2+ -O2-) and tetrahedral site (Fe3+ -O2-) respectively. From the hysteresis loops the magnetic features viz. Hc, Mr and Ms were determined. Further dielectric studies and AC conductivity of the prepared samples is performed. © 2023, The Authors.

We report the direct evidence of impacts of the Coulomb interaction in a prototypical Weyl semimetal, MoTe2, that alter its bare bands in a wide range of energy and momentum. Our quasiparticle interference patterns measured using scanning tunneling microscopy are shown to match the joint density of states of quasiparticle energy bands including momentum-dependent self-energy corrections, while electronic energy bands based on the other simpler local approximations of the Coulomb interaction fail to explain neither the correct number of quasiparticle pockets nor shape of their dispersions observed in our spectrum. With this, we predict a transition between type-I and type-II Weyl fermions with doping and resolve its disparate quantum oscillation experiments, thus highlighting the critical roles of Coulomb interactions in layered Weyl semimetals. © 2021, CC BY-NC-ND.

Background: Frailty is a marker of poor prognosis in older adults with hematologic malignancies and contributes to the severe vulnerability of the aging population to adverse health outcomes. This study aimed to determine the association between frailty and outcomes in hospitalized patients with chronic myeloid leukemia (CML). Methods: The International Classification of Diseases (ICD-10) identified data on hospitalized patients 20 years or older admitted with CML between 2016 and 2018 in the US National Inpatient Sample (NIS) database. The cohort was further divided into groups of patients with or without frailty. Logistic regression analysis was performed to determine associations between study variables and clinical outcomes. A stratified analysis of the association between frailty and in-hospital mortality by age group was also performed. Results: A total of 13,849 hospitalized patients with CML were included, 49.6% of whom had frailty. The mean age of the patients was 65.1 years, and 7,619 (56.2%) of them were male. Frailty was associated with nearly 4 times the risk of in-hospital mortality, 3 times the risk of unfavorable discharge, 3 times the risk of prolonged LOS, and significantly more in total hospital costs. In addition, frailty was associated with a significantly increased risk of in-hospital mortality in all age subgroups (< 40 years, 40–59 years, and > 60 years) compared with no frailty. Conclusions: Frailty strongly predicts poor clinical outcomes in US patients with CML. © 2023, The Author(s).

Plastic pollution is a widespread issue that poses a threat to agroecosystems. Recent data on microplastic (MP) pollution from compost and its application to soil have highlighted the potential impact of micropollutants that may be transferred from compost. Thus, we aim with this review to elucidate the distribution-occurrence, characterization, fate/transport, and potential risk of MPs from organic compost to gain comprehensive knowledge and mitigate the adverse impacts of compost application. The concentration of MPs in compost was up to thousands of items/kg. Among micropollutants, fibers, fragments, and films are the most common, with small MPs having a higher potential to absorb other pollutants and cause harm to organisms. Various synthetic polymers, including polyethylene (PE), polypropylene (PP), polyethylene terephthalate (PET), polystyrene (PS), polyvinyl chloride (PVC), polyester (PES), and acrylic polymers (AP), have been widely used of plastic items. MPs are emerging pollutants that can have diverse effects on soil ecosystems, as they can transfer potential pollutants from MPs to compost and then to the soil. Following the microbial degradation scheme, the transfer chain from plastics to compost to soil can be broken down into main stages, i.e., colonization - (bio)fragmentation - assimilation - and mineralization. Microorganisms and adding biochar play an essential role during composting, which can be an effective solution to enhance MP degradation. Findings have shown that stimulating free radical generation could promote the biodegradation efficacy of MPs and possibly remove their occurrence in compost, thereby reducing their contribution to ecosystem pollution. Furthermore, future recommendations were discussed to reduce ecosystem risks and health challenges.

Spinal muscular atrophy (SMA) is a neurodegenerative disease characterized by the selective loss of spinal motor neurons (MNs) and concomitant muscle weakness. Mutation of is known to cause SMA, and restoring SMN protein levels via antisense oligonucleotide treatment is effective for ameliorating symptoms. However, this approach is hindered by exorbitant costs, invasive procedures, and poor treatment responses of some patients. Here, we seek to circumvent these hurdles by identifying reliable biomarkers that could predict treatment efficacy. We uncovered that MiR34 exhibits consistent downregulation during SMA progression in both human and rodent contexts. Importantly, family-knockout mice display axon swelling and reduced neuromuscular junction (NMJ) endplates, recapitulating SMA pathology. Introducing MiR34a via scAAV9 improved the motor ability of SMNΔ7 mice, possibly by restoring NMJ endplate size. Finally, we observed a consistent decreasing trend in MiR34 family expression in the cerebrospinal fluid (CSF) of type I SMA patients during the loading phase of nusinersen treatment. Baseline CSF MiR34 levels before nusinersen injection proved predictive of patient motor skills 1 year later. Thus, we propose that MiR34 may serve as a biomarker of SMA since it is associated with the pathology and can help evaluate the therapeutic effects of nusinersen.

This study investigated the influence of the inoculant Al-5.0Nb-0.5B on the microstructure and mechanical properties of the AA 2017 alloy fabricated using laser-based powder bed fusion (L-PBF). The AA 2017 alloy powder was obtained through gas atomization and then mixed with 2 wt% of Al-5.0Nb-0.5B powder (20–53 µm) and synthesized using the L-PBF technique. The small addition of the Al-5.0Nb-0.5B, coupled with specific processing parameters, led to a reduction in the fraction of cracks and transformed the solidification structure from cellular to equiaxial. Additionally, it resulted in a grain size reduction down to 4.0 ± 2.9 µm and a low fiber texture. Due to the refined grains, the AA 2017 samples with 2 wt% Al-5.0Nb-0.5B exhibited a high yield strength of 215 ± 33 MPa and ultimate compressive strength of 602 ± 47 MPa, compared to the AA 2017 alloy samples, which exhibited yield strength of 171 ± 8 MPa and ultimate compressive strength of 427 ± 46 MPa. The addition of a small fraction of Al-5.0Nb-0.5B to the AA 2017 alloy, produced by L-PBF, is a promising alternative for manufacturing lightweight parts with a lower amount of hot cracks and equiaxial microstructure. The results show that the use of inoculant with the micrometric size is an effective alternative to the use of nanoparticles, which has a higher safety risk, is usually difficult to homogenize and may promote agglomeration. © 2025 Elsevier B.V.

The food processing industry highlights the daily generation of large amounts of eggshell solid residue. In this way, this residue becomes a non renewable raw material to be reused as an additive in red ceramics, in order to reduce the volume of disposal to the environment and improve the physical properties of the product. The objective of this work was to evaluate the forming moisture, linear shrinkage of drying and shrinkage of drying burning of ceramic test pieces (CS's) with formulations with 2% and 3% of white eggshell residue (ER) incorporated in clay. The clay and ER were collected in the city of Pelotas-RS. The ER sample was analyzed by X-Ray Fluorescence (XRF) and X-Ray Diffraction (XRD). After pressing, natural and artificial drying was carried out and the CS's were burned. These were evaluated through normative parameters C-020/95, C-021/95 and C-026/95. The values obtained for the forming moisture were between 5.82 and 8.78%, for the linear shrinkage of drying between 0.10 and 0.43% and, for the linear contraction burning between -0.29 and 0.08%. The results showed that the addition of ER to the ceramic mass helped in the reduction of the forming moisture and the linear shrinkage of the ceramic test pieces. © 2018 materials Research Society.
