A aluminium, magnesium B aluminium, silicon C phosphorus, magnesium D phosphorus, silicon 16 Sodium, aluminium and silicon are three elements in Period 3. Each element forms an oxide. Which row has three correct properties of these oxides? sodium oxide aluminium oxide silicon dioxide A basic ...
Which of the elements in the following periodic table are halogens? What main group in the periodic table has elements with the largest electron affinities for each period? What group of elements has only unstable negative ions? What is the atomic number of the ...
By processing the large set of sensor readings, this chip-scale system can reconstruct the spectral features of incident light in the visible to near-infrared (IR) spectral range. Another pioneering work employed a single compositionally engineered nanowire as the key active element of an ultra-...

The presence of mobile ions in metal halide perovskites has been shown to adversely affect the intrinsic stability of perovskite solar cells (PSCs). However, the actual contribution of mobile ions to the total degradation loss compared with other factors such as trap-assisted recombination remains ...
Background subtraction is a widely used operation in the video surveillance, aimed at separating the expected scene (the background) from the unexpected entities (the foreground). There are several problems related to this task, mainly due to the blurred
PHOTOSENSITIVE ELEMENT FOR SILVER SALT DIFFUSION TRANSFER PROCESS PURPOSE:To form the finer particles of the low concn. region of a positive image and to decrease the min. density by adding a halogen at an excess ratio per mol of silver to silver particles and adding a thioxyanic acid compd...
Many corrosion problems are caused by the presence of microorganisms, so-called microbiologically influenced corrosion (MIC). A major representative of MIC
Elastic folding, a phenomenon widely existing in nature, has attracted great interests to understand the math and physical science behind the topological transition on surface, thus can be used to create frontier engineering solutions. Here, we propose a topo-optical sensing strategy with ultra-high...
