After complete degassing, the solution was poured into a mold and irradiated with ultraviolet light (365 nm) with a power density of ~4 mW cm−2 for 4 h under the protection of nitrogen, obtaining a PAM/CS composite hydrogel. Then, the composite hydrogel was immersed in a 2...
The demonstrated 3D integration of lasers and ultralow-loss waveguides leverages the advantages of evanescent coupling for vertically spaced photonic functionality layers. This architecture provides a design space for complex on-chip photonic systems without being constrained by in-plane process incompatibilit...
In addition, strongly carbonated silicate melt is thought to be partly responsible for the presence of oceanic low-velocity zones10,17. Despite extensive studies on the occurrence and stability of carbonate-rich melts, physical properties (such as density, viscosity and mobility) of carbonate melts ...
Ultra Motion actuators are consistently relied on for thrust vector control of rocket engines due to their exceptional mechanical reliability, high power density, and dynamic performance capabilities. Our actuators have been integral to the engine control systems of several successful first-stage orbital ...

In three-dimensional light microscopy, the heterogeneity of the optical density in a specimen ultimately limits the achievable penetration depth and hence the three-dimensional resolution. The most direct approach to reduce aberrations, improve the contrast and achieve an optimal resolution is to minimise...
For practical application, a thermoelectric module should not require any external cooling element to establish a large ΔTwhen subjected to a heat source. Because of the comparatively low thermal conductivity of the polymer gel (κ = 0.136 W m−1 K−1, details can be found ...
densities. This observation further corroborates the data shown in Fig.3fbut also points to a complex dependence of Raman intensities on current density and the nature of the interface (Al vs Al-LMLOWvs Al-LMHIGH). Additionally, we have observed that Al triple-complex is always formed for ...
The magnitude and depth of the induced current depends on factors such as the dimension of the element that has undergone induction heating, electrical resistivity, magnetic permeability, and frequency of the alternating current (Equation (1)). 𝑑=3160𝜌𝜇𝑓−−−√d=3160ρμf (1)...
With the segmented finite element method, the tube wall temperature distribution on the FSH of the boiler under different loads was obtained. Compared with previous methods, the method reported in this study is a better fit with the actual operation of the boiler, and more accurately reflects ...
