Black Silicon Revisited as an Ultrabroadband Perfect Infrared Absorber over 20 μm Wavelength Range
Advanced Photonics Research, 2023 Black silicon properties are investigated in the wavelength range extending from 0.2 to 25 μm with a focus on the mid‐infrared (MIR). It is demonstrated that concurrently increasing the initial level of doping of bare silicon, with given limits, enables ...

Advanced Engineering Materials, EarlyView.The presented study focuses on the fracture behaviour of carbon‐bonded magnesia MgO–C refractories, where environmentally friendly fructose, collagen and lignin serve as temporary binding agents. The partial substitution of the source material with recycled MgO–C reduces the fracture resistance, which can be counteracted by the additional introduction ...

Advanced Engineering Materials, EarlyView.Four‐point bending tests are conducted in an argon atmosphere on commercial MgO‐C brick grades with and without MgO‐C recyclate from room temperature up to 1300 °C. No detrimental effect of the MgO‐C recyclates on bending strength is found. Instead, a decisive influence of the total carbon content is observed, with lower total carbon contents ...

Interview on \u3cem\u3eThe Black Box Society\u3c/em\u3e [PDF]
, 2014 Hidden algorithms drive decisions at major Silicon Valley and Wall Street firms. Thanks to automation, those firms can approve credit, rank websites, and make myriad other decisions instantaneously. But what are the costs of their methods?

Advanced Engineering Materials, EarlyView.Collagen hydrolysate is evaluated as a sustainable binder for MgO‐C refractories. Its thermally induced cross‐linking and gas release lead to expansion and cracking in large bricks, but tailored batches with lignin, recyclates, or fine graphite improve the gas release while thermal treatment and stability.

Modeling of Optical Properties of Black Silicon/Crystalline Silicon [PDF]
Journal of Scientific and Industrial Metrology, 2016 Black Silicon, a surface modification of silicon has low reflectance and correspondingly high absorptance in the visible range of wavelengths making it more viable than crystalline silicon for applications in silicon optoelectronics. Like crystalline Si, black silicon has potential applications in solar cells, sensors, antibacterial surfaces and offers
