This paper presents an evaluation of high-dynamic-range (HDR) video tone mapping on a small screen device (SSD) under reflections. Reflections are common on mobile devices as these devices are predominantly used on the go. With this evaluation, we study the impact of reflections on the screen and how different HDR video tone mapping operators (TMOs) perform under reflective conditions as well a...

Lithium-ion batteries (LIBs) have been widely used in the field of portable electric devices because of their high energy density and long cycling life. To further improve the performance of LIBs, it is of great importance to develop new electrode materials. Various transition metal oxides (TMOs) have been extensively investigated as electrode materials for LIBs. According to the reaction mecha...

Hydrous transition metal oxides (TMOs) are redox-active materials that confine structural water within their bulk, organized in 1D, 2D, or 3D networks. In an electrochemical cell, hydrous TMOs can interact with electrolyte species not only via outer surface but also inner surface, which transport to the interior of material. Many operating aqueous environment transform TMOs, then serve as elect...

A sol-gel optical chemical sensor encapsulated with complexing agents for simultaneous detection of selected heavy metals such as chromium and iron in aqueous media was fabricated. The sensor was prepared by acid catalyzed copolymerization of tetramethoxysilane(TMOS) and starch. 300μL of TMOS and starch mixture was load to the 96 well plate and then the gelation was completed within 2 hours. Th...

Ultra-hydrophobic bilayer coatings on a glass surface were fabricated by sol-gel process using hexadecyltrimethoxysilane (C16TMS) and tetramethoxysilane (TMOS) (1:4 molar ratio) as precursors. After coating, silica nanoparticles (SiO₂ NPs) functionalized with different mono-alkoxy derivatives (methoxytrimethylsilane, TMeMS; ethoxydimethylvinylsilane, DMeVES; ethoxydimethylphenylsilane, DMePhES;...

Ternary metal oxides (TMOs) with flexible band structures are of significant potential in the field photocatalysis. The efficient utilization renewable and green solar energy is great importance to developing photocatalysts. To date, a wide range TMOs systems has been developed as photocatalysts for water air purification, but their practical applications visible light-assisted chemical reactio...

This paper presents a temperature sensor system providing the reference of TMOS-based thermal detectors, in order to enable contactless absolute measurements. The proposed directly employs few pixels TMOS detector as sensing element, thus detecting local temperature, while readout circuit is integrated on separate chip. features two-phase time-domain architecture, which provides biasing element...

We examined the structural reconfiguration after intercalating foreign additives, that is, tetramethoxysilane (TMOS), within already formed supramolecular nanolayers of hexadecyltrimethoxysilane (HDTMS). Our experiments indicated that the newly formed interdigitated structure is a thermodynamically more stable configuration. Even after the HDTMS formed initial bilayer-by-bilayer structures, mix...
