The optical performance of random and periodic textured mono crystalline silicon surfaces for photovoltaic applications

EPJ Photovoltaics, 2022
Surface textures that result in high optical yields are crucial for high efficiency photovoltaic (PV) devices. In this work three different texturing approaches are presented that result in smooth concave structures devoid of sharp features.

Laboratory characterization of temperature induced reflection cracks

Journal of Traffic and Transportation Engineering (English Edition), 2020
A hot-mix asphalt (HMA) overlay is one of the primary strategy for rehabilitating existing HMA pavements and Portland cement concrete (PCC) pavements. The current design program, FAARFIELD, does not address reflective cracking for asphalt-overlaid concrete pavements due to its mechanism complexity.

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

FEBS Letters, EarlyView.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

Time perspective, depression, and substance misuse among the homeless [PDF]

, 2008
Using the Zimbardo Time Perspective Inventory (ZTPI; P. G. Zimbardo & J. N. Boyd, 1999), the authors found that homeless people, in comparison with a control group, had a significantly more negative outlook concerning their past and present as evinced by

Discussion on Road Reflection Crack and Control

IOP Conference Series: Materials Science and Engineering, 2020
Abstract This paper focused on the problems encountered in the road construction of a coal-fired power plant in the Philippines as an example. Some cracks and damage appeared in the roadbed after the road concrete base layer has been built.

Review of reflective cracking in composite pavements

International Journal of Pavement Research and Technology, 2020
Reflective cracking is identified as the main weakness of composite pavement in airfield and highways forcing the authorities to devote a large portion of their budget to rehabilitation and/or reconstruction of the existing composite pavements. It is, therefore, very important to have a better understanding of the reflective cracking mechanism to ...
