Exchange Interactions and High-Energy Spin States in Mn_12-acetate

open access: yes, 2004
We perform inelastic neutron scattering measurements on the molecular nanomagnet Mn_12-acetate to measure the excitation spectrum up to 45meV (500K). We isolate magnetic excitations in two groups at 5-6.5meV (60-75K) and 8-10.5meV (95-120K), with higher ...

Argon Cold Plasma Modification of Polyethylene Films to Tailor Surface and Barrier Properties

open access: yesJournal of Applied Polymer Science, EarlyView.
Argon cold plasma treatment of low‐density polyethylene (LDPE) and high‐density polyethylene (HDPE) films induces major changes in surface chemistry and morphology. Contact angles decrease significantly while surface energy increases, improving wettability. FTIR confirms the formation of polar functional groups, while pronounced etching, roughness, and

Autoantibody Response Toward Chromatin in Patients With Juvenile Idiopathic Arthritis

open access: yesArthritis &Rheumatology, EarlyView.
Objective Patients with juvenile idiopathic arthritis (JIA) frequently exhibit antinuclear antibodies (ANAs), but the specific antigen target recognized by them and the presence of additional autoantibody specificities in patients with JIA remains elusive.

Optimizing Measurement of Communication in Autistic Children and Their Caregivers: Dependability of the Caregiver‐Child Interaction

open access: yesAutism Research, EarlyView.
ABSTRACT Despite widespread use of caregiver‐child interactions (CCX) to evaluate outcomes in autism interventions, little research has examined the dependability of this measure. This study applied generalizability theory to determine optimal conditions for dependable assessment of child communication and caregiver implementation of communication ...

A Sustainable and Low‐Cost Zn‐Lignosulfonate Redox Flow Battery

open access: yesBatteries &Supercaps, EarlyView.
A cost‐effective Zn/lignosulfonate (NaLS) hybrid flow battery using 20 kDa NaLS delivers 3.52 Ah L−1 at 30 mM, with an average discharge voltage of 1.01 V, outperforming smaller NaLS. This sustainable design leverages industrial and bio‐based lignosulfonates, cheaper size exclusion membrane, and abundant Zn for ecofriendly, scalable energy storage ...
