Advanced Science, EarlyView.A humidity‐tolerant triboelectric nanogenerator is developed using conductive carbon black‐modified silicone rubber and a flame‐retardant gas barrier layer. The device efficiently harvests footstep energy while maintaining stable output under 30–90% RH and over 1 million cycles.

Spectrophotometric determination of phosphorus in coal and coal ash using bismuth-phosphomolybdate complex [PDF]
Journal of the Serbian Chemical Society, 2003 A modified spectrophotometric method using the bismuth phosphomolybdate complex for the determination of phosphorus in coal and coal ash is suggested. Bismuth together with phosphate and molybdate forms a very stable complex in acid medium which turns ...

Advanced Science, EarlyView.By encapsulating industrially relevant fabrics with dynamic imine networks, we show that the resulting composites exhibit exceptional oil absorbtion capability and chemical recyclability. It is poised for sustainable oil spill cleanup. ABSTRACT The development of high‐performance sorbents for oil spill remediation is highly desirable, which now calls ...

L'armement charbonnier Marcesche (1898-1939) [PDF]
Codrul Cosminului, 2012 In France, Lorient, city located in Brittany, is representative of the medium-sized ports. But how to explain the creation of an industrial and coal shipyard group in the last years of the 19th century in the port of Lorient?

Too Little Oil, Too Much Coal: Optimal Carbon Tax and when to Phase in Oil, Coal and Renewables [PDF]
Our main message is that it is optimal to use less coal and more oil once one takes account of coal being a backstop which emits much more CO2 than oil. The way of achieving this is to have a steeply rising carbon tax during the initial oil-only phase, a

Advanced Science, EarlyView.In the H‐type electrolytic cell, carbon dioxide is reduced to acetic acid via electro‐microbial catalysis. The simply processed acetic acid is further converted through biological fermentation into high‐value‐added products, including acrylic acid, L‐lactic acid, and β‐alanine.

Advanced Science, EarlyView.This study fabricates Fine Slag/Ti4O7@TiC hybrids with interfacial dioxygen bridge coupling to optimize oxygen redox dynamics in lithium‐oxygen batteries (LOBs). Lattice distortion from oxygen vacancies and inherent charge repulsion of Ti‐O‐C interfacial coupling reconstruct and refine the surface coordination environment.

Investigation and Measurement of Ash Content of Coal in Zirab Coal Mine-Iran Using Dual Energy -Ray and X-Ray Fluorescence Methods [PDF]
Iranian Journal of Chemistry & Chemical Engineering, 2000 Coal with low ash content has an important role in the coal and steel industry. There are different methods to measure the ash content. The conventional method which is used in most coal mines of Iran, is to burn the coal and measure the remaining ash. A

Robust Smart Superhydrophobic Cilia
Advanced Science, EarlyView.To date, ciliated surfaces cannot withstand mechanical damage because cilia/wires are inherently fragile. By aligning magneto‐responsive, flexible, superhydrophobic microwires on the sidewall of vertical frames, the frames act as armors to protect microwires from mechanical damage; when needed, the microwires re‐align uprightly under a magnet field to ...
