A computational study proposes a coordination-and-distance rule for hydrogen in metal defects and uses it to reproduce a two-peak thermal-desorption profile in tungsten.
The two tryptophan forms produced different colors and particle arrangements, while absorbance at one wavelength tracked the share of d-tryptophan in test mixtures.
Mice given the nanoparticle formulation Nowarta110 through the skin, oral mucosa or vagina once daily for 12 weeks showed no consistent treatment-related harm across clinical, laboratory, organ and tissue checks.
A network analysis linked four conventional antiepileptic drugs to different osteoporosis-related protein hubs. Docking and molecular-dynamics results added detail, but the findings remain preliminary signals rather than clinical evidence.
In a laboratory comparison, NiPc-OTh showed the strongest measured interaction with Cu2O, while thiophene-anchored variants recorded higher CO activity on carbon nanotubes than unanchored NiPc.
A rat study found higher serum calcium, phosphate and alkaline phosphatase in fracture groups receiving free zingiberene or a zingiberene-selenium formulation than in fracture controls. The formulation's alkaline phosphatase reading was higher than free zingiberene's, but magnesium did not differ significantly between treatments.
A hydrogel carrying Lycium barbarum glycopeptide released more cargo under acidic lab conditions and was associated with faster wound closure in mice, but the study did not establish long-term safety or performance in other wound models.
Ferucarbotran samples produced increasingly anisotropic SAXS patterns as the static magnetic field rose, giving researchers a way to compare three measures of orientational order.

A preprint reports broad, large dielectric responses in pressed BiFeO3 nanopowders with nominal Sm substitutions. The strongest features depended on temperature, frequency and composition, while phase mixtures and particle agglomeration left the mechanism unresolved.
A theoretical preprint reports exact cancellation of the long-range infrared divergence for same-parity elastic exciton scattering, while opposite-parity inelastic coupling remains finite in the model.
A laboratory comparison found distinct Raman changes around the ice-water transition, but the proposed link to latent heat still needs direct calorimetric validation.
A laboratory study of hafnia ferroelectric films found that some regions roughened and leaked during electrical scanning, while others stayed smooth and switched. The researchers link the contrast to uneven chemistry at the underlying interface and report a processing test on one film.
A literature-based Feature Article traces how polaritonic systems exchange energy, carry excitations and show reported changes in charge mobility, while highlighting gaps in the models used to describe them.

A computational preprint reports lower adsorption-enthalpy errors from new MOF models, alongside a large dataset and a literature benchmark that leave broader performance questions open.
Projected q-shells retained more smooth-function information and produced lower one-electron and molecular benchmark errors than standard nested gausslets in the reported calculations.
A critical review of lead-halide perovskites presents a testable framework linking their electronic structure, screening and carrier motion. It also warns that claims about universal defect tolerance, bulk ferroelectricity and dynamic Rashba effects remain unproven.
A laboratory preprint reports that photon emission from transmitted helium ions varied strongly with exit charge state, while differences among carbon, silicon and silicon carbide were small.
A laboratory preprint reports that light may leave optically addressable traps in BaF2, with changes in luminescence yield and a spatial readout of excitation sites.
A laboratory comparison of MoS2 growth on five crystalline substrates found sharply different domain shapes, coverage patterns and optical responses under nominally matched conditions.
A study of three Ag-Au-Pd-Pt thin-film libraries found that work function predicted acidic hydrogen-evolution activity, but correcting hydrogen adsorption for surface coverage left work function with only a small additional contribution.
A catalyst made with cyanobacterial extract achieved higher reported crystal violet degradation and total organic carbon removal than chemically synthesized NiO/CoO, though the tests used prepared dye solutions rather than real wastewater.
Amine-functionalized biochar made from walnut shells produced high reported yields for two reaction types in water at room temperature, but the study was small and descriptive.
The study compared Bauhinia purpurea leaf-extract-mediated zinc oxide nanoparticles made by co-precipitation and sol-gel synthesis in carbon-steel corrosion tests, with lower dissolved iron reported at 100 ppm than in the blank.
A computational study of carbon dioxide reacting with surface hydrogen on Cu(111) predicts that rotational excitation may influence reaction probability more strongly than bending vibration, while leaving the mechanism to be tested experimentally.
A model-free graph analysis reconstructed 158 HDO energy levels from 686 initially unassigned transitions. Broadband tests in acetylene and methane also measured line-position repeatability and identified unusual spectral features.
OrbGNN represents molecular orbitals as graph nodes and uses their connections to predict correlation energies and spin-state gaps in three computational tests.
A combined photoemission and modeling study found that Fe and Mn deposits were associated with different surface-band changes in lead-tin selenide, depending on coverage and crystal orientation.
The method gave finite model clusters an open-boundary response, but the tests were limited to idealized calculations and the authors say it is not yet a complete embedding framework.
A preprint argues that cobalt ordering and correlated electronic states may help explain why a layered iron telluride remains antiferromagnetic near 250 K.
A computational materials study used generated crystal structures and energy calculations to screen rare-earth alloys, finding its highest modeled magnetization in iron-rich candidates while leaving experimental stability untested.
A model tracked published lithium and cobalt leaching data reasonably well in lower-acid conditions, but its peroxide predictions ran high at the strongest acid level.
A review of direct-current thermo-mechanical testing finds that the method can support mechanism studies, model calibration and rapid creep screening, but it is not a universal substitute for bulk furnace testing.
A modeling study highlights NiPt- and CoIr-based alloy families as the main source of its largest predicted anomalous Hall and Nernst responses. The authors propose exchange splitting, the separation between spin channels, as a way to choose parent compounds for chemical substitution. The findings are computational predictions from a virtual crystal screen.
A hierarchical modeling workflow screened 30,364,908 generated structures and produced 97 predicted room-temperature solid-state electrolyte candidates, most of them halides. Agreement with independent experimental halide patterns was a consistency check, not direct validation.
