A comprehensive review on perovskite and its functional composites in smart textiles: Progress, challenges, opportunities, and future directions

The Influence of the Skin Phenomenon on the Impedance of Thin Conductive Layers

“…The formulae for the derivatives of the A 0 potential need to determine the components of magnetic induction and to calculate the normal derivative occurring in condition (5). In the general case:…”

“…Those types of structures can also be used as the active part of sensors for pathogens detection [3]. Taking into account the developing 5G and 6G technology, such structures will also be used for data transmission, e.g., in smart healthcare and industrial manufacturing [4][5][6]. According to reports from the Huawei 6G research team [7], research is being conducted on integrated sensing and communications with optical wireless (ISAC-OW) technology to develop solutions such as holographic hospitals and industrial automation.…”

A dual-responsive microemulsion with macroscale superlubricity and largely switchable friction

“…The advantages of employing stimuli-responsive MEMs as lubricants include their powerful cleaning performance, good affinity to both hydrophilic and hydrophobic surfaces, unique properties in providing lubrication and cooling simultaneously due to the coexistence of lubricating oil/additive and water, and tuneable tribological performances based on variations in their physicochemical properties. 16,18,20,22–24 As one of the most frequently used external stimuli to trigger the variations in both properties of materials and biological signals in the human body, 16,25–28 temperature is advantageous in its remote controllability, good reversibility and no accumulation of impurities such as inorganic salts in the system, which may therefore allow in-time and in-space control of the tribological behaviour of a MEM simply, rapidly and non-invasively. In addition to effective regulation of its tribological properties by switching an applied magnetic field “on” and “off”, a magneto-responsive MEM could become “active” upon exposure to external magnets and be manipulated by them.…”

Dual-ligand quasi-2D perovskites with chiral-induced spin selectivity for room temperature spin-LEDs

“…23,24 The funnel-like graded bandgap profile in the quasi-2D perovskite film allows cascaded carrier transfer from a low- n to a high- n phase. 25–29 Long et al reported 3% spin-polarized luminance in quasi-2D perovskites using the chiral methylbenzylammonium (MBA) cation as the spacer, in which the spin-polarized luminescence depends on the spin-polarized exciton transfer between the chiral 2D and achiral high- n phase. 30 However, the polarization is only achieved at 2 K due to the short spin lifetime of the exciton because of the large exciton binding energy of the chiral 2D phase.…”
