The effects of whole‐body vibration amplitude on glucose metabolism, inflammation, and skeletal muscle oxygenation

Whole‐body vibration (WBV) is an exercise mimetic that elicits beneficial metabolic effects. This study aims to investigate the effects of WBV amplitude on metabolic, inflammatory, and muscle oxygenation responses. Forty women and men were assigned to a high (HI; n = 20, Age: 31 ± 6 y) or a low‐amplitude group (LO; n = 20, Age: 33 ± 6 y). Participants engaged in 10 cycles of WBV [1 cycle =1 min of vibration followed by 30 s of rest], while gastrocnemius muscle oxygen consumption (mVO(2)) was assessed using near‐infrared spectroscopy (NIRS). Blood samples were collected PRE, POST, 1H, 3Hs, and 24H post‐WBV and analyzed for insulin, glucose, and IL‐6. In the LO group, Homeostatic Model Assessment for Insulin Resistant (HOMA‐IR) at 3 h (0.7 ± 0.2) was significantly lower compared to PRE (1.1 ± 0.2; p = 0.018), POST (1.3 ± 0.3; p = 0.045), 1H (1.3 ± 0.3; p = 0.010), and 24H (1.4 ± 0.2; p < 0.001). In addition, at 24H, HOMA‐IR was significantly lower in the LO when compared to the HI group (LO: 1.4 ± 0.2 vs. HI: 2.2 ± 0.4; p = 0.030). mVO(2) was higher (p = 0.003) in the LO (0.93 ± 0.29 ml/min/100 ml) when compared to the HI group (0.63 ± 0.28 ml/min/100 ml). IL‐6 at 3H (LO: 13.2 ± 2.7 vs. HI: 19.6 ± 4.0 pg·ml(−1); p = 0.045) and 24H (LO: 4.2 ± 1.1 vs. HI: 12.5 ± 3.1 pg·ml(−1); p = 0.016) was greater in the HI compared to the LO group. These findings indicate that low‐amplitude WBV provides greater metabolic benefits compared to high‐amplitude WBV

Heat and Light Synergy Response of FTO/CdTe/Bi₂Te₃ Nanostructure Heterojunction Thin Film

CdTe photoelectric material with one-dimensional nanostructure and Bi2Te3 thermoelectric material were successively grown on FTO substrate by magnetron sputtering method for forming FTO/CdTe/Bi2Te3 heterojunction thin film. Whereafter, a power device was prepared by processing Ag electrode. The property of the device with light and heat synergy response was characterized by the V-t curve, which was collected through the circuit and optical path design. With the time difference between light and heat response, the curve of voltage-time was collected under the different light source, electrode contact point and light illumination direction. Meanwhile, the phenomenon of light and heat synergy response was identified with the illumination intensity of halogen and xenon light changeable. The results show that the synergy of photoelectric material and thermoelectric material in a single cell of CdTe/Bi2Te3 heterojunction can realize the light and heat synergy response, and it is anticipated to harvest solar energy from a wider solar spectrum

Anti-laser Irradiation Ability of VO₂ Films Against Pulsed Power Laser

Thermochromic VO2 film was fabricated on quartz substrate through sputtering oxidation coupling method, and its optical properties were also investigated. Results show that the prepared VO2 film exhibits good thermo-optical switching performance under weak light irradiation, while large transmittance changes both in the visible and near-infrared light area. Under the condition of pulsed power laser irratiating, large optical modulation depth is also derived in the infra-red region. With the increase of pulsed laser energy, the scattering coefficient is gradually decreased, and the anti-laser irradiation ability is firstly appeared to have a decline trend after an initial ascent. The minimum transmittance value can reach to 7% and the laser damage threshold is about 50 mJ/cm2
