Deep chemical and structural investigation of battery components is increasingly imperative for exploring new electrode materials their performance iterations the next-generation energy storage devices with high density. This particularly true in research realm lithium (Li) metal its derivatives robust anode. Conventionally, both Li solid electrolyte interphase (SEI) layer are chemically reacti...

In this paper, an NO2 optical fiber sensor is presented for pollution monitoring in road traffic applications. This sensor exploits the simultaneous transmission of visible light, as a measurement signal, and UV light, for the recovery of the NO2 sensitive materials. The sensor is based on a multimode fiber tip coated with a thin film of lutetium bisphthalocyanine (LuPc2). The simultaneous inje...

Herein, the fabrication of light-sensitive high-aspect ratio surfaces with switchable topography using melt-electrowriting shape-memory polymers and deposition light-to-heat converting black ink on it by dip coating is reported on. The lamellae exposed to low temperatures are hard cannot be deformed water droplets. temperature reached upon illumination close melting point soft segment polyureth...

Polarization-sensitive photodetectors are demonstrated using solution-synthesized CdSe nanowire (NW) solids. Photocurrent action spectra taken with a tunable white light source match the solution linear absorption spectra of the NWs, showing that the NW network is responsible for the device photoconductivity. Temperature-dependent transport measurements reveal that carriers responsible for the ...

It is generally accepted that when multi-component materials are examined with a scanning electron microscope, the contrast differences observed using compositional backscattered electron imaging are due to variations in their average atomic numbers. With increasing atomic number, there is an approximate monotonic increase in backscatter coefficient, which is observed as an increase in the brig...

This work reports the elaboration and structural study of new hybrid organic-inorganic materials constructed via the coupling of liquid-crystalline nonionic surfactants and polyoxometalates (POMs). X-ray scattering and polarized light microscopy demonstrate that these hybrid materials, highly loaded with POMs (up to 18 wt %), are nanocomposites of liquid-crystalline lamellar structure (Lalpha),...

Photodiode (PD) light sensors, PD arrays and image sensors with a wide spectral response, including ultraviolet light (UV-light) waveband of 200-380 nm, are strongly required in the fields of various spectrophotometric analysis, biological phenomena analysis, environmental assessment and space vision1)~4). For the image sensor development, an improvement of UV-light sensitivity and an improveme...

In the monolayer limit, transition metal dichalcogenides become direct-bandgap, light-emitting semiconductors. The quantum yield of light emission is low and extremely sensitive to the substrate used, while the underlying physics remains elusive. In this work, we report over 100 times modulation of light emission efficiency of these two-dimensional semiconductors by physical adsorption of O2 an...
