The amount and distribution of water in nominally anhydrous minerals (NAMs) are usually determined by Fourier-transform infrared spectroscopy. This method is limited by the spot size of the beam to the study of samples with dimensions greater than a few micrometers. Here, we demonstrate the...

Tandem organic solar cells are based on the device structure monolithically connecting two solar cells to broaden overall absorption spectrum and utilize the photon energy more efficiently. Herein, we demonstrate a simple strategy of inserting a double bond between the central core and end groups...

Modern optical nano-elements pursue ever-smaller sizes and individualized functionalities. Those elements that can efficiently manipulate the magnetic field of light boast promising future applications with a great challenge: the magnetic near field is irretrievable from conventional optical far-field characterization. Here we propose photoinduced magnetic force...

The performance of catalysts depends on their nanoscale properties. However, heterogeneities in the structure and composition of catalytic materials makes it difficult to directly monitor and identify the influence of local physicochemical parameters on their global reactivity. FTIR spectroscopy have been widely employed to probe...

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,...

PiFM images of the CsFAMA film, sequentially recorded in the a) pristine state, b–f) after being subjected to voltage stressing with the amplitude of −1 to −0.2 V and i–n) after being subjected to voltage stressing with the amplitude of 0 to 1 V and a ramping...
Mitrovic, A., Nagel, W., Leang, K., Clayton, G.
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)...

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...

Integrated photoelectrochemical devices rely on the synergy between components to efficiently generate sustainable fuels from sunlight. The micro- and/or nanoscale characteristics of the components and their interfaces often control critical processes of the device, such as charge-carrier generation, electron and ion transport, surface potentials, and...

The surface plasmon resonance of copper in the near infrared region provides a novel method for enhancement of up-conversion luminescence compared to using gold and silver, as the former grants significant cost savings. In this study, we made a flat Cu film covered TiO2 to...

Nonfullerene acceptors (NFAs) have attracted great attention in high-efficiency organic solar cells (OSCs). While the effect of molecular properties including structures and energetics on charge transfer has been extensively investigated, the effect of macroscopic-phase properties is yet to be revealed. Here we have performed a...

Mesoporous silica particles of controlled size and shape are potentially beneficial for many applications, but their usage may be limited by the complex procedure of fabrication. Biotemplating provides a facile approach to synthesize materials with desired shapes. Herein, a bioinspired design principle is adopted through...
