Abstract Advanced heat‐managing textiles not only improve the comfort of individual but also reduce energy consumption systems building. To meet demand in a dynamic environment, responsive with tunable thermal convection and radiation have been developed, while design fabrics conduction remains unexplored. Here, humidity‐driven flexible conductance regulating material is developed that shows an unprecedented switching ratio up to 14×, which composed brick‐and‐mortar structured graphene silk...
Despite universal endoscopic screening, early detection of gastric cancer is challenging, led researchers to seek for a novel approach in detecting. Raman spectroscopy measurements as fingerprint biochemical structure, enable accurate prediction lesions non-destructively. This study aimed evaluate the diagnostic power (EGC), and reveal dynamic biomolecular changes vitro from normal EGC. To clarify alterations Correa's cascade, spectra human mucosa, intestinal metaplasia, dysplasia,...
The phonon magic angle of 2D puckered homostructures, with the TP-1 and TP-2 directions overlapped, retains a high level or even an enhanced transport capability due to van der Waals (vdW) confinement.
The one-dimensional geometry of silicon nanowire helps to overcome the rigid and brittle nature bulk enables it withstand substantial bending stresses. This provides exciting opportunities for development flexible electronics. strain introduces atomic displacement in lattice structure, which inherently has a significant impact on thermal conductivity. strain-dependent conductivity is crucial management performance electronic devices. However, situ measurement nanowires remains challenging...
The thermal conductivity measurement of metal–organic frameworks (MOFs), which plays an important role in management MOF-based gas separation, storage, and energy conversion (e.g., adsorption heat pumps), has been a challenging task for decades. However, the direct single-crystal MOF is currently limited by their small crystal sizes, since no sophisticated approach ever reported. In this study, Raman-resistance temperature detectors (Raman-RTDs) method was developed situ measuring ZIF-8,...
Traps filled in the off-state of high electron mobility transistors (HEMTs) are a primary factor contributing to performance instability power devices. These traps capture leakage electrons, causing instantaneous current fluctuations and drift threshold voltage. Realizing spatial resolution measurements for (OFTs) has become prerequisite optimizing device structure exploring failure mechanism. However, existing methods mainly detect overall integral result unable indicate in-plane...
We propose a label-free method to analyze bodily fluids based on surface-enhanced Raman scattering (SERS) with large laser spot-swift mapping and involving the electrochemistry preparation of silver nanoparticle substrates. This can overall properties multicomponent liquid identify low-concentration components. A spot formed by scanning galvanometer is used obtain an average spectrum from different samples, whereas swift detects components such as tumor biomarkers. The substrates exhibit...
Nanoparticles are widely used in composite materials, nanoscale devices, biological detectors and medical treatment. The thermophysical properties of a single nanoparticle are, therefore, important for both nanotechnology nanoscience applications. However, property measurements limited by the spatial resolution conventional measurement methods, so there not yet any effective methods to characterize nanoparticle. This paper describes laser flash Raman spectroscopy method measuring specific...
