Photo-Thermal Solar Energy Conversion Device [PDF]

open access: yes, 2011
Photo-thermal solar energy device was constructed using local available materials for producing hot water for house hold uses. The motivation for this research is to find an alternative source of power for this purpose, since we have epileptic supply ...

Colloidal Crack Sintering Lithography for Light‐Induced Patterning of Particle Assemblies

open access: yesAdvanced Functional Materials, EarlyView.
Colloidal crack sintering lithography (CCSL) is a microfabrication technique that uses light‐induced photothermal heating to trigger sintering and controlled cracking in polymer colloidal assemblies. Local structural changes generate microchannels and patterns, enabling direct writing of diverse topographic motifs.

Spatiotemporal Plasma–Mediated Laser Fabrication of Ultrahigh‐Aspect‐Ratio Nanochannel Arrays for Vertical Perovskite Nanowire Semiconductor Devices

open access: yesAdvanced Functional Materials, EarlyView.
A spatiotemporal plasma–mediated laser processing approach is developed to fabricate ultrahigh–aspect ratio nanochannel arrays and corresponding perovskite nanowire arrays within transparent materials for optoelectronics devices. The laser‐fabricated nanochannels serve as templates for controlled perovskite infiltration and crystallization, enabling ...

Mesoporous Carbon Thin Films with Large Mesopores as Model Material for Electrochemical Applications

open access: yesAdvanced Functional Materials, EarlyView.
Mesoporous carbon thin films possessing 70 nm mesopores are prepared on titanium substrates by soft templating of resol resins with a self‐synthesized poly(ethylene oxide)‐block‐poly(hexyl acrylate) block copolymer. A strategy to avoid corrosion of the metal substrate is presented, and the films are extensively characterized in terms of morphology ...

Returned Solar Max hardware degradation study results [PDF]

open access: yes
The Solar Maximum Repair Mission returned with the replaced hardware that had been in low Earth orbit for over four years. The materials of this returned hardware gave the aerospace community an opportunity to study the realtime effects of atomic oxygen,

Efficient NiOx Hole Transport Layers Enabled by Multifunctional MXenes for High‐Performance Tin‐Lead Perovskite Solar Cells

open access: yesAdvanced Functional Materials, EarlyView.
An efficient NiOx HTL is successfully prepared by introducing MXene as an additive without further surface modification to fabricate high‐performance FASn0.5Pb0.5I3 perovskite solar cells. The introduction of MXene contributes to improved conductivity of NiOx, better aligned at NiOx/perovskite interfaces, and enhanced quality of perovskite films ...

Neutron and gamma ray production in the 1991 June X-class flares [PDF]

open access: yes
We present new calculations of pion radiation and neutron emission from solar flares. We fit the recently reported high energy GAMMA-1 observations with pion radiation produced in a solar flare magnetic loop. We calculate the expected neutron emission in
