Highly emissive semiconductor nanocrystals, or so‐called quantum dots (QDs) possess a variety of applications from displays and biology labeling, to quantum communication and modern security. Though ensembles of QDs have already shown very high photoluminescent quantum yields (PLQYs) and have been widely utilized in current optoelectronic products, QDs that exhibit high absorption cross‐section, high...
The development of skin organs for studying developmental pathways, modeling diseases, or regenerative medicine purposes is a major endeavor in the field. Human induced pluripotent stem cells (hiPSCs) are successfully used to derive skin cells, but the field is still far from meeting the goal of creating skin containing appendages, such as hair follicles and sweat glands. Here, the goal is to generate...
Stimuli‐responsive ion nanochannels have attracted considerable attention in various fields because of their remote controllability of ionic transportation. For photoresponsive ion nanochannels, however, achieving precise regulation of ion conductivity is still challenging, primarily due to the difficulty of programmable structural changes in confined environments. Moreover, the relationship between...
Rechargeable aqueous zinc‐ion batteries (ZIBs) are promising in stationary grid energy storage due to their advantages in safety and cost‐effectiveness, and the search for competent cathode materials is one core task in the development of ZIBs. Herein, the authors design a 2D heterostructure combining amorphous vanadium pentoxide and electrochemically produced graphene oxide (EGO) using a fast and...
Sb2S3 is an attractive solar absorber material that has garnered tremendous interest because of its fascinating properties for solar cells including suitable band gap, high absorption coefficient, earth abundance, and excellent stability. Over the past several years, intensive efforts have been made to enhance the photovoltaic efficiencies of Sb2S3 solar cells using many promising approaches including...
To enhance the catalytic activity of the nanozymes for efficient wound healing infected with multidrug‐resistant bacteria, photo‐based motivations have been suggested, but attention is mainly focused on the external stimulus of near‐infrared light, while the inexhaustible visible one is promising but lack of study. Herein, an efficient visible light‐stimulated peroxidase‐like nanozyme system, TiO2...
2D‐layered materials have attracted increasing attention as low‐cost supports for developing active catalysts for the hydrogen evolution reaction (HER). In addition, atomically thin Ti3C2Tx (MXene) nanosheets have surface termination groups (Tx: F, O, and OH), which are active sites for effective functionalization. In this work, heteroatom (boron)‐doped Ti3C2Tx (MXene) nanosheets are developed...
Magnetic hyperthermia (MH) harnesses the heat‐releasing properties of superparamagnetic iron oxide nanoparticles (SPIONs) and has potential to stimulate immune activation in the tumor microenvironment whilst sparing surrounding normal tissues. To assess feasibility of localized MH in vivo, SPIONs are injected intratumorally and their fate tracked by Zirconium‐89‐positron emission tomography, histological...
Nanoscrolls are a class of nanostructures where atomic layers of 2D materials are stacked consecutively in a coaxial manner to form a 1D spiral topography. Self‐assembly of chemical vapor deposition grown 2D WS2 monolayer into quasi‐1D van der Waals scroll structure instigates a plethora of unique physiochemical properties significantly different from its 2D counterparts. The physical properties of...
