In response to the demand for real-time non-destructive detection of delamination defects in curved structure carbon fiber–reinforced polymer (CFRP), an anisotropic CFRP model was constructed based on laser thermal elastic effect, and generation propagation ultrasonic waves inside CFPR were analyzed. On this basis, orientation information defect is obtained by calculating time it takes transverse wave reach surface probe after encountering defect. When with size 1×0.2 mm located between...
We propose a scheme to achieve the field-free molecular orientation around half rotational periods with combination of single- and dual-color laser pulses. show that can be obtained controlled by precisely controlling time delay between two Furthermore, we discuss effect intensity pulse duration single-color on created pulse, depends change in alignment degree odd even wave-packet contributions pulse.
Antibiotics are widely used for treatment of bacterial infections, and their overuse has contributed to microbial resistance. Currently, an alternative antibiotic-free therapy inactivating bacteria is great interest. Black phosphorus (BP), a biocompatible nontoxic rising-star two-dimensional layered material, gained remarkable interest in many bioapplications including biosensing, cancer therapy, drug delivery, also antibacterial treatment. However, BP nanosheets suffer from instability...
Background/Aims: Atherosclerosis is associated with dysfunction of endothelial progenitor cells (EPCs). Tripterine, a chemical compound derived from the Chinese medicinal plant Tripterygium wilfordii Hook, displays anti-inflammatory properties in several animal models. We hypothesized that tripterine can improve EPC function and thus efficiency transplantation. Methods Results: Tripterine preconditioning (2.5 μM, 4 h) improved proliferation, tube formation, migration, adhesion, reduced...
We report on the coherent control of boosted ultrashort terahertz pulses emitted from air plasma pumped by a femtosecond sawtooth pulse composed three optical harmonic fields. With an inline setup, relative phases between components pump can be varied independently with attosecond precision without complexity external phase stabilization. observe that amplitude emission phase-optimized wave is enhanced 1.8 times compared to widely used two-color scheme. Moreover, manipulating colors at...
In this paper, we theoretically show that the field-free molecular orientation created by a single dual-color laser pulse can be significantly enhanced separating it into two time-delayed subpulses. It is indicated maximum enhancement of subpulses achieved with their intensity ratio about 1:2 and simultaneously applying second one at beginning rotational wave packet rephasing or end dephasing induced first one. also shown suppression coherently manipulated varying relative phase between...
We theoretically demonstrate that the terahertz-spectrum generation in three-color laser-gas interactions can be effectively manipulated by tuning laser wavelengths. show positive and negative detuning of one color wavelengths pulse, terahertz spectral range greatly expanded, particular, high frequency components emerge. However, total energy is maintained at a relatively level even significantly increase. Moreover, we also middle spectrum tuned modulating relative wavelength pulses....
Flexible and transparent anti-counterfeiting films have aroused great attention for their potential applications in information security assurance of product quality recently. Much has been focused on the crystalline structure matrix; however, studies amorphous alumina hosts are limited. Here, an doped with Eu3+ phosphor was successfully synthesized by a soft chemical route. Its evolution, morphology, photoluminescence features were analyzed. The host offers free access simultaneously avoids...

The behavior is slow turn-on rapid turn-off Furthermore, we modulation has slight advantage in enhancing comparing it under intensity.

Human tissue adjacent normal were surgically removed, immunohistochemistry Western blotting detect expression. development pathological characteristics...
The dysfunction of endothelial progenitor cells (EPCs) limits their potential for the treatment ischemia and atherosclerosis. Therefore, we investigated effect tripterine on EPC function examined underlying mechanisms. tripterine, an active component Tripterygium wilfordii Hook, enhancement efficiency transplantation was in vitro vivo. Treatment EPCs with at 2.5 µM 4 h inhibited oxidized low‐density lipoprotein (ox‐LDL) induced ROS production, cell apoptosis, senescence improved migration...
Abstract Background and Aims: The present study was carried out to test the hypothesis that interferon‐α (IFN‐α) treatment would reduce or postpone recurrence rate improve overall survival in patients after transarterial chemoembolization (TACE) of hepatitis B virus (HBV) related unresectable hepatocellular carcinoma (HCC). Methods: 216 with HBV‐related HCC were randomized into a TACE group TACE‐IFN group, each had 108 patients. In received IFN‐α1b at dose 3 million units (mu) three times...
In this paper, we theoretically show that the field-free molecular alignment can be controlled by shaping femtosecond laser pulse with a periodic phase step modulation, involving maximum degree and temporal structure of alignment. We completely suppressed or reconstructed as transform-limited pulse, transient desired shape, antialignment for any switched. Furthermore, also both direction at fix time delay continuously modulated.
We study theoretically terahertz generation in two-color laser-gas interactions based on a transient photocurrent model. show that depends the laser pulse duration and intensity of field. Furthermore, amplitude increases with an increase at low intensity, but decreases high intensity. Our analysis shows ionization events play important role is determined by superposition contributions from individual events.
We experimentally demonstrate the control of single and two-photon fluorescence (SPF TPF) in Er3+ ions by shaping femtosecond laser pulse with a π or square phase modulation. With low intensity (8.4 × 1010 W/cm2), SPF keeps constant while TPF is effectively suppressed two schemes. high (1.2 1013 both are simultaneously enhanced modulation, The up/down-conversion enhancement, suppression, tuning optical method can greatly expand its applications various related fields.
