We compared conventional microscope-based methods for quantifying biomass and community composition of stream benthic algae with output obtained for these parameters from a new instrument (the BenthoTorch), which measures fluorescence of algal pigments in situ. Benthic algae were studied in 24 subarctic oligotrophic (…
In this paper, an inexpensive and magnetically recyclable copper ferrite–graphene hybrid nanocomposite was synthesized and used as an efficient catalyst for the reduction of nitroarenes for the first time.
We report a dual functional aggregation-enhanced emission (AEE) molecule, TPE-IQ, which could target and illuminate mitochondria in both live and fixed cells with superb selectivity and high signal-to-noise ratio. More intriguingly, TPE-IQ can serve as a photosensitizer to generate reactive oxygen species (ROS) in the…
Titanium nitride (TiN) coated silicon nanoparticles were synthesized via the reduction of TiO 2 -coated silicon nanoparticles under nitrogen.
Photothermal therapy, as a physical therapeutic technique to kill cancer, has generated a great deal of interest. Photothermal agents hence play a critical role in this modern therapy. We report the use of transition metal oxides as photothermal agents based on PEGylated WO3-x nanoparticles. The well-prepared nanopart…
A novel asymmetric polybenzimidazole (PBI) membrane used for high temperature proton exchange membrane fuel cells has been successfully fabricated by a soft-template method using the ionic liquid 1-ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide ([EMIM][TFSI]) as the porogen. Typically, the asymmetric PBI…
The properties of isomeric azulene derivatives, substituted through the 5-membered ring, were examined using a combination of experimentation and theoretical calculations for a series of well-defined electroactive oligomers.
Cu + -doped MIL-101 was synthesized, and its application in the separation of olefin–paraffin was investigated for the first time.
Light-emitting electrochemical cells (LECs) containing [Cu(POP)(N^N)][PF6] (POP = bis(2-diphenylphosphinophenyl)ether, N^N = 6-methyl- or 6,6'-dimethyl-2,2'-bipyridine) exhibit luminance and efficiency surpassing previous copper(I)-containing LECs.
Electrical properties of TiO 2 /CH 3 NH 3 PbI 3 heterojunction solar cells.
The p K a 1 values and NBO charges of 32 carboxylate ligands and 31 N -heterocyclic ligands were calculated at 298.15 K with the B3LYP/6-31+G(d,p) level of calculations, which are useful to understand the water and thermal stability of Metal–Organic Frameworks (MOFs).
Microfluidics offers great tools to produce highly-controlled dispersions of gas into liquid, from isolated bubbles to organized microfoams. Potential technological applications are manifold, from novel materials to scaffolds for tissue engineering or enhanced oil recovery. More fundamentally, microfluidics makes it p…
The ability to precisely tune the chemical compositions and electronic structures of nanoalloy catalysts is essential to achieve the goals of high activity and selectivity for the oxygen reduction reaction (ORR) on the catalysts by design. In this work, we synthesized carbon-supported Pt-Co alloy nanoparticles with co…
We report an efficient route for the sonochemical synthesis of undoped BiPO4, Ag3PO4 and silver doped BiPO4:Ag(x%) (x = 2, 5, 10 and 20) nanostructures using bismuth/silver nitrate and ammonium dihydrogen phosphate as precursors. The products obtained have been characterized using X-ray diffraction (XRD), scanning ele…
Chemical functionalization can be used to tune optoelectronic properties of indigoids, their stability and semiconductor performance in OFETs.
Plants of Brassica juncea L. var. RLC-1 were exposed for 30 days to different concentrations (0, 0.2, 0.4, and 0.6 mM) of cadmium (Cd) to analyze the Cd uptake, H2O2 content, hormonal profiling, level of photosynthetic pigments (chlorophyll, carotenoid, and flavonoid), gaseous exchange parameters (photosynthetic rate,…
Nanostructured niobium oxide (NO) semiconductors are gaining increasing attention as electronic, optical, and electro-optic materials. However, the preparation of stable NO nanofilms with reproducible morphology and behavior remains a challenge. Here we show a rapid, well-controlled, and efficient way to synthesize NO…
In problems of indentation of an elastic half-space by a rigid sphere, the effects of surface tension outside the contact zone are not accounted for by classical theories of contact mechanics. However surface tension plays a dominant role in determining the mechanics of this adhesive contact when the half-space become…
In-doped Bi2Se3 hierarchical nanostructures have been synthesized by an in situ cation exchange route from their template of In3Se4 nanostructures. Through detailed structural, chemical, and morphological characterizations, it has been found that, after the cation exchange, the In-doped Bi2Se3 hierarchical nanostructu…
We report a new approach of using dispersed water phase gelation as a mode to create oil continuous emulsion gels. Low temperature gelation property of synergistic hydrocolloid combinations was exploited to develop elastic soft solids using only food-grade components.
