Online monitoring of thermal comfort in non-uniform and asymmetry thermal environments is essential for achieving more intelligent and efficient vehicle cabin thermal environment management. This study introduces a new approach that provides real-time feedback to a Heating, Ventilation, and Air Conditioning (HVAC) system controller concerning the occupants' thermal sensation through non-intrusive measurements. Specifically, the cabin thermal environment is divided into multiple thermal zones and a hybrid model is proposed. The hybrid model contains two sub-models, a data-driven model and a physics-based model. The data-driven model is a temperature soft sensor that non-intrusively estimates the thermal environment parameters for each thermal zone and passes the results to the physics-based model. The physics-based model can predict the overall thermal sensation of each occupant and consider the weighted effect of local thermal sensation on the overall thermal sensation. Two vehicles' cabin thermal environment data and twenty young subjects' thermal comfort votes were collected, including both cooling and heating conditions. We conclude that the hybrid model can infer cabin thermal environment parameters and thermal comfort based on limited sensors, specifically providing thermal comfort monitoring for occupants in each seating position, which has not been much investigated in previous research. In this regard, our research will contribute to broadening the consideration of individualized thermal comfort in existing vehicles. • Online monitoring of thermal comfort in non-uniform thermal environments. • Cabin's non-uniform thermal environment is divided into multiple thermal zones. • A soft sensor that non-invasively estimates the temperature of each thermal zone. • A hybrid model that provides thermal comfort monitoring for occupants in each seat. • The dataset includes cooling and heating conditions for different seasons.

Nanocomposite AgBr@HPU-4 was synthesized based on a 3D Cu-MOF, {[Cu(L) 0.5 (H 2 O) 2 ]·4H 2 O} n (HPU-4) through a facile reaction route and confirmed by XRD, TEM, SEM. UV–Vis absorption spectrum indicates that AgBr@HPU-4 nanocomposite has strong optical capability nearly in the whole range of visible light spectrum. The as-prepared AgBr@HPU-4 photocatalyst, as compared to AgBr or HPU-4 , exhibits enhanced photocatalytic activity towards the degradation of Methylene Blue and Methyl Orange dyes.

A Cu(I)/Cu(II) 3D framework, {[(CuII) 3 (CuI) 3 (pbt) 3 Cl 2 ]·ClO 4 ·H 2 O} n ( HPU-3 ) (H 2 pbt = 5′-(pyridin-2-yl)–2H,4′H-3,3′-bi(1,2,4-triazole)), has been synthesized by using solvothermal method. UV–Vis absorption spectrum indicates that HPU-3 has strong optical capability nearly in the whole range of visible light spectrum. HPU-3 photocatalyst exhibits good photocatalytic activity toward the degradation of Methylene Blue and Methyl Orange dyes. [ABSTRACT FROM AUTHOR]

This paper reports a metal ion-exchange material which can significantly enhance the degradation of acetamiprid and methylene blue. [Display omitted] A Metal-Organic Framework (MOF) by the formula of {[Cd 4 (L) 2 (H 2 O) 3 ]·4·.5H 2 O} n (HPU-15-Cd) (H 4 L = 5, 5′-oxydiisophthalic acid) has been synthesized via solvothermal method. The central ions of HPU-15-Cd can occur ion-exchange with Co2+/Cu2+ ions to form the isostructural HPU-15-Co, HPU-15-Cu in a single-crystal-to-single-crystal fashion. Photocatalytic experiments showed that HPU-15-Co, HPU-15-Cu had better photocatalytic activity for the degradation of acetamiprid (ACT) and methylene blue (MB) than HPU-15-Cd. The reason is that the band gap width of HPU-15-Co and HPU-15-Cu is narrow, which makes it have higher absorption and utilization of UV–visible light. Besides, HPU-15-Cd, HPU-15-Co, HPU-15-Cu have excellent stability, and the catalytic effect of HPU-15-Cu are basically unchanged after three cycles of catalytic degradation of ACT and MB.
