As one of the most delicate bioprocesses in nature, biosilicification is closely related to biosilica with various morphologies, and has provided abundant inspiration to materials synthesis. In the present study, to explore the biosilica formation process and fabricate silica with an exquisite microstructure for lithium-ion...

Infrared photoinduced force microscopy (IR-PiFM) is a scanning probe spectroscopic technique that maps sample morphology and chemical properties on the nanometer (nm)-scale. Fabricated samples with nm periodicity such as self-assembly of block copolymer films can be chemically characterized by IR-PiFM with relative ease. Despite the...

Hot‐electron injection induced by plasmon decay enables ultrafast electron transfer in femtosecond scale and therefore endows metallic nanoparticles (MNPs) promising potentials in high‐speed optoelectronics. With much higher density of states next to its Fermi level, palladium (Pd) can more efficiently launch hot electrons according to...
Song, J., Ye, L., Li, C., Xu, J., Chandrabose, S., Weng, K., Cai, Y., Xie, Y., O'Reilly, P., Chen, K., Zhou, J., Zhou, Y., Hodgkiss, JM., Liu, F., Sun, Y.
Morphological stability is crucially important for the long-term stability of polymer solar cells (PSCs). Many high-efficiency PSCs suffer from metastable morphology, resulting in severe device degradation. Here, a series of copolymers is developed by manipulating the content of chlorinated benzodithiophene-4,8-dione (T1-Cl) via a random copolymerization...

Effective separation and transfer of photogenerated charge carriers are common issues in solar energy conversion. Strong localized electric fields near functional nanostructures reduce charge recombination and boost energy efficiency and photocatalytic activity. However, common metal-based photocatalytic systems on conducting supports under-utilize infrared (IR) light energy,...

In this paper, a closed-loop control framework for dual-stage nanopositioning systems is presented that allows the user to allocate control efforts to the individual actuators based on their range capabilities. Recent work by the authors has focused on range-based control of dual-stage actuators implemented as...

The control of the growth of hematite nanoparticles from iron chloride solutions under hydrothermal conditions in the presence of two different structure promoters has been studied using a range of both structural and spectroscopic techniques including the first report of photo induced force microscopy (PiFM)...
Zhang, X., Jiang, Q., Wang, J., Tang, J.
Black phosphorus quantum dots (BPQDs), as 2D van der Waals crystals, possess remarkable electronic and optoelectronic properties. Their excellent ultra-high mobility and thickness-dependent tunable direct bandgap can meet well the needs of polymer solar cells (PSCs) for adjustable energy levels in different active layer systems....
Jahng, J., Son, JG., Kim, H., Park, J., Lee, TG., Lee, ES.
Chemical characterizations of biochemically functionalized single nanoparticles are necessary to optimize the nanoparticle surface functionality in recently advanced nanobiological applications but have not yet been fully explored because of technical difficulties. Exploiting the photoinduced force exerted on a light-illuminated nanoscale tip, nanoscale mid-infrared hyperspectral images...
