Petroleum extraction generates large volumes of produced water (PW), which is an effluent containing high concentrations of pollutants that impact the environment and present a significant environmental liability for the fossil fuel industry. Among the various treatment approaches, biological methods—particularly those involving microalgae—have shown promise for PW remediation. In this study, we evaluated the bioremediation potential of PW using a microalga Chlorolobion braunii cultivated in 250 L photobioreactors. C. braunii was cultivated in a mixture containing 50 % PW and 50 % BG-11 (Blue green 11) medium (PW50%), while the control comprised only the BG-11 medium. Results demonstrated high removal efficiencies for nitrate (99.54 %), phosphate (77.78 %), iron (94 %), and manganese (75 %), along with a reduction in alkalinity (61 %). A total of 40 g of biomass was produced using 100 L of PW, containing 8.50 % lipids. This biomass mainly contained palmitic acid (C16:0) and elaidic acid (C18:1ω9t), indicating its suitability for biodiesel production according to the International Quality Standards of the American Society for Testing and materials (ASTM D6751 ) and the Brazilian National Agency of Petroleum, Natural Gas, and Biofuels (ANP). The biomass also yielded 35.12 % bio-oil and 57.69 % non-condensable gases during pyrolysis. Furthermore, 30 g of exopolysaccharides (EPS) were obtained, which exhibited pseudoplastic characteristics—a property of industrial interest. Thus, the treatment using 50 % PW for the cultivation of C. braunii was deemed a promising strategy for bioremediation and facilitated the production of high-value bioproducts.

Research into mechanically interlocked luminescent molecules (MILMs), which is the overlapping of mechanically interlocked molecules and luminescent molecules, has intensified over the past few decades. These studies have tapped into and exploited the benefits of mechanically interlocked structures to achieve outstanding and stimulus-responsive optical characteristics, resulting in the synthesis of new types of luminescent systems and exploring their potential uses in different applications. This review describes the salient attributes of MILMs and showcases some of the latest advancements in this field of research.

Using soft x-ray absorption spectroscopy we were able to determine unambiguously the charge and spin states of the transition metal ions in stoichiometric YCu3Co4O12 and CaCu3Co4O12. The trivalent and low-spin nature of both the Cu and Co ions in YCu3Co4O12 makes this correlated system to be effectively a nonmagnetic band semiconductor. The substitution of Y by Ca produces formally tetravalent Co ions but the doped holes are primarily on the oxygen ligands. Concerning the spin degrees of freedom, the trivalent Co ions in YCu3Co4O12 remain low spin upon the Y-Ca substitution, very much unlike the La1−xSrxCoO3 system. The tetravalent Co ions in CaCu3Co4O12 are interestingly also in the low-spin state, which then explains the good electrical conductivity of CaCu3Co4O12 since charge exchange between neighboring Co3+ and Co4+ ions will not be hampered by the spin-blockade mechanism that otherwise would be in effect if the Co4+ and Co3+ spin quantum numbers were to differ by more than one-half. We infer that the stability of the Co low-spin state is related to the very short Co-O bond lengths.

We have studied the magnetic response of transverse optical phonons in Pb1−xSnxTe films. Polarization-dependent terahertz magnetospectroscopy measurements revealed Zeeman splittings and diamagnetic shifts, demonstrating that these phonon modes become chiral in magnetic fields. Films in the topological crystalline insulator phase (x > 0.32) exhibited magnetic moment values that are larger than those for topologically trivial films (x Copyright © 2022, The Authors.

Correlated quantum phenomena in one-dimensional (1D) systems that exhibit competing electronic and magnetic order are of strong interest for studying fundamental interactions and excitations, such as Tomonaga-Luttinger liquids and topological orders and defects with properties completely different from the quasiparticles expected in their higher-dimensional counterparts. However, clean 1D electronic systems are difficult to realize experimentally, particularly magnetically ordered systems. Here, we show that the van der Waals layered magnetic semiconductor CrSBr behaves like a quasi-1D material embedded in a magnetically ordered environment. The strong 1D electronic character originates from the Cr-S chains and the combination of weak interlayer hybridization and anisotropy in effective mass and dielectric screening with an effective electron mass ratio of meX/meY ∼ 50. This extreme anisotropy experimentally manifests in strong electron-phonon and exciton-phonon interactions, a Peierls-like structural instability and a Fano resonance from a van Hove singularity of similar strength of metallic carbon nanotubes. Moreover, due to the reduced dimensionality and interlayer coupling, CrSBr hosts spectrally narrow (1 meV) excitons of high binding energy and oscillator strength that inherit the 1D character. Overall, CrSBr is best understood as a stack of weakly hybridized monolayers and appears to be an experimentally attractive candidate for the study of exotic exciton and 1D correlated many-body physics in the presence of magnetic order.

Kramers nodal lines (KNLs) have recently been proposed theoretically as a special type of Weyl line degeneracy connecting time-reversal invariant momenta. KNLs are robust to spin orbit coupling and are inherent to all non-centrosymmetric achiral crystal structures, leading to unusual spin, magneto-electric, and optical properties. However, their existence in in real quantum materials has not been experimentally established. Here we gather the experimental evidence pointing at the presence of KNLs in SmAlSi, a non-centrosymmetric metal that develops incommensurate spin density wave order at low temperature. Using angle-resolved photoemission spectroscopy, density functional theory calculations, and magneto-transport methods, we provide evidence suggesting the presence of KNLs, together with observing Weyl fermions under the broken inversion symmetry in the paramagnetic phase of SmAlSi. We discuss the nesting possibilities regarding the emergent magnetic orders in SmAlSi. Our results provide a solid basis of experimental observations for exploring correlated topology in SmAlSi. © 2022, CC BY-NC-SA.

The isotopic compositions of samples returned from Cb-type asteroid Ryugu and Ivuna-type (CI) chondrites are distinct from other carbonaceous chondrites, which has led to the suggestion that Ryugu/CI chondrites formed in a different region of the accretion disk, possibly around the orbits of Uranus and Neptune. We show that, like for Fe, Ryugu and CI chondrites also have indistinguishable Ni isotope anomalies, which differ from those of other carbonaceous chondrites. We propose that this unique Fe and Ni isotopic composition reflects different accretion efficiencies of small FeNi metal grains among the carbonaceous chondrite parent bodies. The CI chondrites incorporated these grains more efficiently, possibly because they formed at the end of the disk’s lifetime, when planetesimal formation was also triggered by photoevaporation of the disk. Isotopic variations among carbonaceous chondrites may thus reflect fractionation of distinct dust components from a common reservoir, implying CI chondrites/Ryugu may have formed in the same region of the accretion disk as other carbonaceous chondrites. © 2024, CC BY.
