- We explore the potential of nanocrystals (a term used equivalently to nanoparticles) as building blocks for nanomaterials, and the current advances and open challenges for fundamental science developments and applications. Nanocrystal assemblies are inherently multiscale, and the generation of revolutionary material properties requires a precise understanding of the relationship between structure and function, the former being determined by classical effects and the latter often by quantum effects. With an emphasis on theory and computation, we discuss challenges that hamper current assembly strategies and to what extent nanocrystal assemblies represent thermodynamic equilibrium or kinetically trapped metastable states. We also examine dynamic effects and optimization of assembly protocols. Finally, we discuss promising material functions and examples of their realization with nanocrystal assemblies.

- Hospital buildings are required to secure a variety of indoor environments according to the diverse requirements of patients and staff. Among these requirements, thermal comfort is an important design criterion for indoor environmental quality that affects patients' healing processes and the wellbeing of medical staff. The patients' thermal comfort is given priority due to their medical conditions and impaired immune systems. Thermal comfort and related contexts have been well-covered in many research articles; however, the number of review articles is limited. This article aims to conduct a holistic and critical review of existing studies offering insights on future research trends (180 articles were analyzed). The key research themes are identified using scientometric analysis. Focus is on influencing factors, field-surveys, improving measures and energy saving related to thermal comfort. The primary outcome concludes that ventilation systems play a key role in maintaining acceptable, thermally-comfortable conditions for patients and medical staff. It is also found that acceptable thermal comfort is highly case-dependent and varies substantially based on the health condition of the patient as well as the type and level of staff activities. The measures currently mentioned to minimize energy consumption are also discussed. Some interesting issues, including the inaccuracy arising from the use of predicted mean vote (PMV) and the impact of gender, age, and related factors on thermal comfort, have been noted. This review provides insights into the design and assessment of hospital thermal environments.

Exploration of ultrafast dynamic processes in photocatalysis : Advances and challenges

Forskningsöversikt (refereegranskat)abstract
- Photocatalysis plays a crucial role in harnessing renewable energy by efficiently converting solar energy into chemical energy. Adequate cognition of photogenerated charge carrier dynamics in photocatalysis is the key to realizing efficient solar energy utilization, and provides guidance for breaking through the efficiency bottleneck. However, a convincing correlation between those photophysical processes and the photocatalytic performance has yet been established due to the complexity of photocatalytic reactions. In this review, we overviewed the detailed ultrafast photophysics in photocatalysis based on three typical ultrafast spectroscopic techniques (TRPL, TA and TRIR), and put a special focus on the justification as well as the limitation on correlating those photophysics with the actual catalytic performance. The classification of carrier behaviors after photoexcitation as well as typical time-resolved spectroscopic characterization techniques are briefly introduced first. State-of-the-art studies on the excited state dynamics in photocatalysis and its correlation to catalytic performance are then systematically presented from three types of common photocatalysts including quantum dots, polymeric photocatalysts, and traditional semiconductors. Finally, a summary on the correlation between ultrafast photophysics and the final photocatalytic performance is provided, and challenges and limitations of current photophysical characterization to rationalize the catalytic performance are outlined.
