APPLIEd PHYSICS LETTErS 1997年第1期71卷 46-48页

We report observation of reverse saturable absorption in C-60 toluene solution for 10 ns duration laser pulses in the wavelength region 710-740 nm, for which the photon energy is less than the energy of the lowest excited singlet state. The observed nonlinear absorption appears to be due to excitation of molecules to the more absorbing lowest triplet state by direct absorption from the ground state. Our results imply that a C-60 based optical limiter can operate over a broad spectral range extending into the near-infrared. (C) 1997 American Institute of Physics.

It is necessery to investigate the buckling mechanism in order to obtaining good performance from various sensors composed of resistors and microbridges or membranes. Especially for flow sensors, a convex formed bridge has an advantage over a flat or concave bridge with respect to heat transfer coefficient. We have fabricated various shapes of bridges and have prepared SiNx sputtered films as the support films of microbridges and Pt sputtered or evaporated films as resistors. We have achieved deformation control for both the longitudinal axis and transverse axis of Pt/SiNx double layered microbridges by appropriate selection of the total residual stress of Pt/SiNx structures and of the stress gradient between the Pt film and SiNx film. The deformation direction of the longitudinal axis of bridges for the beam bridge (Type I) are all the same as that of cantilevers and may be predicted via the stress gradient between the Pt and SiNx filmes of the bridges. The deflection of the transverse axis of the table bridge supported by four beams (Type II) changes linearly with the total stress of the Pt/SiNx structure and the deformation changes for the transverse axis are the same as that of completely free films as predicted from the stress gradient between the Pt film and the SiNx film. The interesting result is that the deformation direction for the longitudinal axis of Type II is opposite to that of Type I with the same film structure. We discuss the reason for this opposition via differences in the progress of the anisotropic etching. We consider that this result will expand the range of manufacturable shapes and film structures of microbridges.

Caseinolytic protease P (ClpP) protein is essential for prokaryotic and eukaryotic protein homeostasis, and has emerged as a promising bactericidal target for controlling bacterial infection and evading the emergent of drug-resistance risk. As the unique bactericidal mechanism, ClpP loses its substrate specificity and undergoes uncontrolled protein hydrolysis in the presence of an activator, leading to causing bacterial death. To further expand the chemotype of ClpP activator, a series of ONC212 derivatives were synthesized using a ring expansion strategy. Surprisingly, compound A14 showed optimal antibacterial activity against Xanthomonas oryzae pv. oryzae (Xoo) in vitro (EC50 value = 3.86 μg/mL), which was >6 × more potent than the EC50 value of ONC212 (26.42 μg/mL). Molecular docking, fluorescence titration and degradation experiments of the XooFtsZ protein indicated that compound A14 was a strong degrader of XooClpP towards XooFtsZ. In vivo assays showed that the control activity of compound A14 (200 μg/mL) reached 47.47 %, compared to 41.57 %, 36.72 %, and 30.43 % for ONC212, thiodiazole copper, and bismerthiazol, respectively. Overall, this study led to the identification compound A14, which not only showed improved antibacterial potency, and maintained the binding XooClpP, but also highlighted the ring expansion strategy as a promising approach for bactericide discovery. © 2025 Elsevier B.V.

A series of high entropy AB2-type Ti2-xZrxMnCrFeNi alloys (x = 0.6, 0.7, 0.8, 0.9, 1.0, 1.1 and 1.2) were synthesized to investigate their potential for hydrogen storage and chemical compression. The influence of the Ti/Zr ratio was explored in terms of structural, microstructural and thermodynamic properties. The storage capacity together with the reaction enthalpy and entropy changes of the synthesized high entropy alloys were compared to predictions from Machine Learning (ML) to investigate changes in these properties across the explored composition space. The results revealed that a decreasing Zr content consistently lowered the hydride formation enthalpy and increased the plateau pressure from 8 to >90 bar H2 at 25 °C, in good agreement with ML predictions. Selected compositions (x = 1.0 and 1.2) demonstrated reversible hydrogen storage capability over 150 cycles, with capacities of 1.34–1.40 wt % H2 and remarkable reaction kinetics ( © 2025

Sensor strips for self-monitoring of blood glucose are desired to require only small amount of blood sample so the pain of the patients with pricking their fingertips is reduced. In this study, the authors developed a new sensor strip which requires a blood sample of merely 200 nL. An advanced screen-printing technique was employed in the assembling process to attain precise spatial control over the sensor elements such as carbon electrodes and spacers. The measurement accuracy of the new sensor strip was nearly equal to that of the commercially available ones. In the Clarke Error Grid analyses using human blood samples, it was confirmed that all measured points in a glucose concentration range of 8 to 461 mg/dL were within the "A zone". Glucose oxidase (GOd) was used as the enzyme, in order to prevent the misevaluation of the glucose concentration by the presence of maltose in human blood. Good results were obtained for the new blood glucose sensor strip using a blood sample of only 200 nL.

Numerical analysis of low-frequency electromagnetic scattering from axially symmetric bodies using an inductance matrix

IEEE TrANSACTIONS ON MAGNETICS 2006年第5期42卷 1555-1559页

We have proposed a numerical method for calculating low-frequency electromagnetic scattering from axially symmetric conducting bodies with and without apertures. The surface of the perfectly conducting scatterer is modeled by a set of inductively coupled coil elements, and the current in each coil element is computed by solving an inductance matrix equation. A disadvantage of a conventional method for a scatterer with apertures is discussed. Scattering from various axially symmetric conducting bodies with or without apertures is calculated and the resulting fields are in good agreement with those obtained by finite-element method.

Simultaneous breaking of time reversal and inversion symmetries in multiferroics couples ferroelectricity to magnetism and is a source of unusual physical phenomena that can be used in next-generation electronic devices. A notable example is dyFeO3, which under applied magnetic fields exhibits a giant linear magnetoelectric response and a large spontaneous electric polarization induced by coexisting orders of Fe and dy spins. Here, we use high-resolution neutron diffraction to show that at zero field dyFeO3 hosts an incommensurate magnetic soliton lattice formed by spatially ordered dy domain walls with an average domain size of 231(8) Å. The long-ranged interaction between the domain walls is mediated by magnons propagating through the Fe subsystem and is analogous to the Yukawa force in particle physics. An applied magnetic field destroys the long-ranged incommensurate order, unlocks the linear magnetoelectric response and stabilizes the ferroelectric state. The magnetic domain walls are electrically charged and the soliton array dimerizes when both electric and magnetic fields are applied. Numerical simulations with experimental parameters suggest, that the generic competition between the ferroelectric and incommensurate states can be effectively controlled by an applied electric field. © 2025, CC BY.

Modified Kelvin-Voigt fractional derivative model for viscoelasticity measurement in optical coherence elastography

Chinese Optics Letters 2025年第1期 98-106页

Optical coherence elastography(OCE) can quantitatively obtain the viscoelasticity of tissues using rheological models and is widely applied to the clinical diagnosis of diseases. However, commonly used rheological models in OCE do not account for the distinctive dependence of high-frequency storage and loss moduli on frequency in tissues, which results in the rheological models failing to accurately measure the viscoelastic properties of tissues. In this paper, a modified Kelvin-Voigt fractional derivative model is presented based on the power-law behavior of soft tissues and the dependence of high-frequency complex shear modulus on frequency in living cells. In the rheometer and OCE tests, the modified model can provide the prediction of the power-law relationship between the low-frequency shear viscosity and frequency; compared with the Kelvin-Voigt and Kelvin-Voigt fractional derivative models, the modified model has a higher goodness-of-fit(accuracy >96%)for the high-frequency storage moduli of gelatin phantoms. Furthermore, the proposed model can reduce the root mean square error of fit by approximately 83% for the high-frequency(1–128 kHz) storage modulus of the polydimethylsiloxane phantoms obtained from publicly available data. Overall, the modified model accurately predicts the mechanical properties of biomimetic materials over a wide frequency range, with the potential to more accurately reflect pathological changes in tissues.
