Summary: This study aimed to investigate the mitigation of EGCG-induced loss of MP gelling potential by L-Lysine. The addition of 20 mM L-Lys decreased the solubility and tryptophan fluorescence of MP at 10 μmol/g EGCG, leading to the formation of a network structure with a large aperture. Furthermore, L-Lys hindered the interactions between MP and EGCG at 50 μmol/g EGCG, improving the solubility and apparent viscosity of MP gels. These findings provide a new strategy for increasing the amounts of EGCG in meat products without damaging their gel properties.

Summary: Based on 3-D integration technology, a compact sixth-order common-mode noise suppression filter is proposed using delay line theory. The on-chip inductors are established by through-silicon vias (TSVs), and the capacitors are realized by double layer interdigital structure. Compared to other literature, this filter has a very small size of 0.29 x 0.32 mm (0.0203 x 0.0224 lambda(2)(g)). It can suppress common-mode noise by more than 10 dB from 3.8 to 8.6 GHz or by more than 20 dB from 4.45 to 7.85 GHz, while maintaining a differential signal insertion loss of less than 3 dB.

Summary: Recently, the potential therapeutic effects of antibacterial peptides in Alzheimer's disease have been suggested. This study investigated whether human beta-defensins (hBDs) can suppress Pg LPS-induced oxidative and inflammatory responses in microglia. The results showed that hBD3 significantly inhibited the production of nitric oxide and interleukin-6 (IL-6) in mouse and human microglial cells. Furthermore, hBD3 suppressed the translocation of p65 nuclear and inhibited the enzymatic activities of cathepsins B and L, which are necessary for NF-kappa B activation. This study suggests that hBD3 can suppress oxidative and inflammatory responses in microglia by inhibiting cathepsins B and L.

Summary: GaAs photodiode arrays are designed for non-destructive monitoring in synchrotron light sources. By using a shallow p-on-n structure, the device photocurrent density is reduced and optimized for high-power hard x-ray beams. The experimental results are consistent with the modeling predictions, with the exception of higher x-ray energies.

Summary: In this work, we demonstrate the extension of Bragg coherent diffractive imaging using resonant magnetic x-ray scattering to study the mesoscopic texture of an antiferromagnetic order parameter. We successfully extracted the arrangements and sizes of antiferromagnetic domains in PrNiO3 and showed that the approach could be applied to study the motion of dilute domains or topological defects in antiferromagnetic spin textures.

Summary: We studied charge-orbital fluctuations in the insulating state of magnetite using resonant elastic x-ray scattering and x-ray photon correlation spectroscopy. Our results revealed the dynamics of the iron 3d and oxygen 2p orbital domains, showing a decoupling of the orbital correlation lengths between the oxygen ligands and site-specific iron 3d states. We also observed charge-orbital domain fluctuations at the iron t(2g) orbital sites of trimeron chains.

Summary: Understanding phonon-induced relaxation in molecular qubits is crucial for their application potential. Garlatti et al. utilize inelastic X-ray scattering and density functional theory to investigate the role of low-energy phonons on spin relaxation in a prototypical molecular qubit. They find that intra-molecular vibrations with very-low energies are largely responsible for spin relaxation up to ambient temperature. This research provides insights into improving spin coherence and opens new avenues for the investigation of magnetic molecules for quantum devices.

Summary: This study finds that aliovalent doping can be more effective in reducing the lattice thermal conductivity of thermoelectric semiconductors compared to isoelectronic alloying. The introduction of aliovalent dopants leads to the softening and deceleration of optical phonons, resulting in a significant reduction in thermal conductivity. Moreover, the heavy dopant can induce the avoided crossing of acoustic and optical phonon branches, further suppressing phonon propagation.

Summary: Crystalline electric field (CEF) excitations of Nd3+ ions in NdT2Zn20 (T = Co, Rh, and Ir) have been measured using inelastic neutron scattering (INS). Dispersionless excitations were observed at 3.8 and 7.2 meV for T = Co, 3.1 and 5.8 meV for T = Rh, and 3.0 and 5.3 meV for T = Ir in the INS measurements at 5 K. The temperature dependence of the INS spectra confirms that the CEF ground states are the 1'6 doublet, necessary for the manifestation of the magnetic two-channel Kondo effect. A shoulder at 7.7 meV, close to the CEF excitation peak at 7.2 meV, is attributed to a bound state of the CEF and low-lying optical phonon excitations.

Summary: Neutron spectroscopy measurements on NiPS3 single crystals reveal that it is less two-dimensional than its sister compounds, with a relatively large ferromagnetic exchange between the layered ab planes. The analysis also shows the existence of in-plane magnetic exchange interactions up to the third-nearest neighbor. The anisotropy is mainly XY-like with a small uniaxial component, resulting in the appearance of two low-energy spin wave modes.
