Interfacial evaporation using porous hydrogels has demonstrated highly effective solar performance under natural sunlight to ensure an affordable clean water supply. However, it remains challenging realize scalable and ready-to-use hydrogel materials with durable mechanical properties. Here, self-assembled templating (SAT) is developed as a simple yet method fabricate large-scale elastic evaporators excellent desalination performance. The interconnected structure of the low tortuosity...
Harvesting solar energy for vapor generation is an appealing technology that enables substantial eco-friendly applications to overcome the long-standing global challenge of water and crisis. Nonetheless, undesirable low light utilization efficiency large heat losses impede their practical use. Here, we demonstrate a typical design paradigm capable achieving superb nonconvective flow assisted collecting rates 2.09 kg/m2h under 1 sun irradiation with high photothermal conversion up 97.6%. The...
For photocatalytic solar energy conversion, the critical challenge is to enhance utilization efficiency. Many efforts have focused on development of broad-band response nanomaterials. Here, we propose an alternative approach wherein, over Ni2P/TiO2 nanoparticles without noble metal, UV–vis part was absorbed and converted by a semiconductor its infrared separately collected into thermal heat reaction certain temperature. The photothermocatalytic hydrogen activity 3.6 times that sum...
The diheme enzyme MauG catalyzes the posttranslational modification of precursor protein methylamine dehydrogenase (preMADH) to complete biosynthesis its protein-derived tryptophan tryptophylquinone (TTQ) cofactor. Catalysis proceeds through a high valent bis-Fe(IV) redox state and requires long-range electron transfer (ET), as distance between modified residues preMADH nearest heme iron is 19.4 Å. Trp199 resides at MauG-preMADH interface, positioned midway that are heme. W199F W199K...
The diheme enzyme MauG catalyzes posttranslational modifications of a methylamine dehydrogenase precursor protein to generate tryptophan tryptophylquinone cofactor. MauG-catalyzed reaction proceeds via bis -Fe(IV) intermediate in which one heme is present as Fe(IV)=O and the other Fe(IV) with axial histidine tyrosine ligation. Herein, unique near-infrared absorption feature exhibited specifically described, evidence presented that it results from charge-resonance-transition phenomenon. As...
In this study, effects of different nanoparticles and porosity absorber tube on the performance a Concentrating Parabolic Solar Collector (CPSC) were investigated. A section porous-filled was modeled as semi-circular cavity under solar radiation which is filled by nanofluids governing equations solved FlexPDE numerical software. The effect four physical parameters, type, volume fraction (φ), Darcy number (Da) Rayleigh (Ra), Nusselt (Nu) discussed. It turns out that Cu nanoparticle most...
Most photocatalytic reactions are conducted near room temperature. In this work, we explored photothermal hydrogen production in a carefully designed photo reactor with external heating. Light sources of different wavelength bands were investigated. Formic acid was used as sacrificial regent to study the activity. Interestingly, reaction is not simple sum and thermal effects but their synergetic coupling at 90°C it 8.1 4.2 times that under or conditions alone. With excitation, bound...
Thermal conductivity and viscosity are important properties for nanofluids as they significantly affect the flow heat transfer process. To date, rheological of water-based have been well studied, while results scarce non-aqueous nanofluids. In this study, thermal two different kinds oxide (CuO Al2O3) in a typical commercial data center focusing on liquid coolants were systematically investigated at mass fractions temperatures. The showed that addition nanoparticles can improve conduction...
An intriguing mystery about tryptophan 2,3-dioxygenase is its hydrogen peroxide-triggered enzyme reactivation from the resting ferric oxidation state to catalytically active ferrous form. In this study, we found that such an odd Fe(III) reduction by oxidant depends on presence of l-Trp, which ultimately serves as reductant for enzyme. peroxide reaction with 2,3-dioxygenase, a previously unknown catalase-like activity was detected. A ferryl species (δ = 0.055 mm/s and ΔEQ 1.755 mm/s)...
The effect of interaction between hydrophilic nanoparticles and ionic surfactants on the liquid/air interfacial properties has been investigated, a possible mechanism also proposed.
