Study on photothermal properties of Zn-ZnO/paraffin binary nanofluids as a filler for double glazing unit

International Journal of Heat and Mass Transfer, 2022
Abstract Binary nanoparticles may effectively improve photothermal properties of the phase change material (PCM) to expand its application in solar energy, especially in energy-saving window. In the present work, various Zn-ZnO/paraffin binary nanofluids with different concentration and Zn:ZnO ratio are prepared for researching the paraffin ...

Near-Infrared Conjugated Polymers Containing Thermally Activated Delayed Fluorescence Units Enable Enhanced Photothermal Therapy

ACS Applied Materials & Interfaces, 2023
Photothermal therapy (PTT) using near-infrared (NIR) conjugated polymers as photosensitizers has exhibited enormous potential for tumor treatment. However, most NIR conjugated polymers have poor therapeutic efficacy due to their faint absorbance in the NIR region and low photothermal conversion efficiency (PCE).

Synthesis and Near-Infrared Photothermal Conversion of Discrete Supramolecular Topologies Featuring Half-Sandwich [Cp*Rh] Units

Journal of the American Chemical Society, 2021
Although a large number of novel supramolecular topologies featuring half-sandwich [Cp*Rh] units have been reported, investigations into the properties of these architectures are astoundingly rare. In addition, the bidentate ligands employed to prepare these species have remained relatively homogeneous (i.e., symmetrical bis(pyri-4-dyl) ligands).

Charge Transfer Metal‐Organic Framework Containing Redox‐Active TTF/NDI Units for Highly Efficient Near‐Infrared Photothermal Conversion

Chemistry – A European Journal, 2021
AbstractMetal‐organic frameworks (MOFs), as a class of new inorganic‐organic hybrid crystal materials, could have important applications in near‐infrared (NIR) photothermal conversion. Herein, a new charge‐transfer MOF (Co‐MOF) with mixed ligands of H4TTFTB and bpmNDI incorporating redox‐active tetrathiafulvalene/naphthalene diimide (TTF/NDI) units ...

Primary Structural Units “D+A” Ion Pairs Dominating Near-Infrared Photothermal Conversion of Organic Ionic Cocrystals

The Journal of Physical Chemistry Letters, 2023
The specific stacking mode of D/A blocks is often considered to largely determine the physicochemical properties of cocrystals. However, this rule may fail when encountering a large degree of (integer or near-integer) charge transfer situations. Herein, we explore the extensive correlations between the possible smallest structural units, stacking modes,

Integrating Tetrathiafulvalene and Nickel‐Bis(dithiolene) Units into Donor‐Acceptor Covalent Organic Frameworks for Stable and Efficient Photothermal Conversion

Chemistry – A European Journal, 2023
AbstractTetrathiafulvalene (TTF) and Ni‐bis(dithiolene) are typical conductive units widely studied in electronics, optics, and photochemistry. However, their applications in near‐infrared (NIR) photothermal conversion are often limited by insufficient NIR absorption and low chemical/thermal stability.

Number of Seeds per Unit Area in Sunflower Correlates Well with a Photothermal Quotient

Crop Science, 1997
Potential yield in several crop species is affected by radiation and temperature when they are grown under unstressed conditions. This issue has been not explored for sunflower (Helianthus annuus L.), and the objectives of our experiments were (i) to analyze the dependence of seed number (SN, seeds m−2) on the thermal and light conditions during the ...
