A series of heterometallic [3 × 3] grids have been synthesized readily through a one-pot solvothermal reaction. Given metal ions carrying distinct electronic, magnetic, and optical information can be addressed precisely at specific locations in the array.
Synchrotron radiation (SR) X‐ray microscopy combined with X‐ray fluorescence (XRF) microspectroscopy provides unique information that have pushed the frontiers of biological research, particularly when investigating intracellular mechanisms. This work reports an SR‐XRF microspectroscopy investigation on the distributi…
Despite an increased interest in the use of hydrogel encapsulation and cellular self-assembly (often termed "self-aggregating" or "scaffold-free" approaches) for tissue-engineering applications, to the best of our knowledge, no study to date has been undertaken to directly compare both approaches for generating functi…
Hygiene products such as incontinence pads bring nonwoven fabrics into contact with users' skin, which can cause damage in various ways, including the nonwoven abrading the skin by friction. The aim of the work described here was to develop and use methods for understanding the origin of friction between nonwoven fabr…
A series of dye-sensitized solar cells (DSSCs) has been prepared by using indole-based or quinoline-based squaraines (SQs) as the sensitizer and containing the commonly used I 3 – /I – redox pair or the lately employed cobalt complexes, [Co(dimethylbipyridine) 3 ] 3+/2+, [Co(bipyridine) 3 ] 3+/2+, and [Co(phenanthroli…
Cationic arene ruthenium assemblies of the general formulas [Ru 6 ( p -cymene) 6 (tris-pvb) 2 (μ 2 -Cl) 6 ] 6+, [Ru 6 ( p -cymene) 6 (tris-pvb) 2 (OO∩OO) 3 ] 6+ (tris-pvb = 1,3,5-tris{2-(pyridin-4-yl)vinyl}benzene), and [Ru 8 ( p -cymene) 8 (NN∩NN) 2 (OO∩OO) 4 ] 8+ (NN∩NN = 1,2,4,5-tetrakis{2-(pyridin-4-yl)vinyl}benze…
INTRODUCTION: Current therapies for articular cartilage defects fail to achieve qualitatively sufficient tissue regeneration, possibly because of a mismatch between the speed of cartilage rebuilding and the resorption of degradable implant polymers. The present study focused on the self-healing capacity of resident ca…
Colwellia is a genus of mostly psychrophilic halophilic Gammaproteobacteria frequently isolated from polar marine sediments and sea ice. In exploring the capacity of Colwellia psychrerythraea 34H to survive and grow in the liquid brines of sea ice, we detected a duplicated 37 kbp genomic island in its genome based on…
Hierarchical clinoptilolite and L zeolites are prepared using optimized tandem dealumination-desilication treatments. The main challenge in the postsynthetic modification of these zeolites is the high Al content, requiring a tailored dealumination prior to the desilication step. For natural clinoptilolite, sequential…
The possibility of temporally and spatially coherent thermal emission has been demonstrated utilizing stacked gratings. We demonstrate that the metallic grating with narrow air slit behaves like a homogeneous slab with large permittivity and small permeability and find that the interaction between the metallic grating…
The effect of a thin dielectric film on the plasmonic behaviour of metal nanoparticles (MNPs) above a high refractive index substrate is explored. Using finite-difference time domain simulations, the optical properties of Ag nanoparticles are investigated as a function of film thickness, refractive index, and particle…
The success of RNA interference (RNAi) in medicine relies on the development of technology capable of successfully delivering it to tissues of interest. Significant research has focused on the difficult task of systemic delivery of RNAi; however its local delivery could be a more easily realized approach. Localized de…
Photopolymerization on a thiol–ene elastomer is a novel method to spatiotemporally control wrinkle formation gradients and complex patterns. Acrylate-rich elastomers, containing photoinitiator and photoabsorber, were strained and irradiated with UV light to generate wrinkles in as little as five seconds. The presence…
There is significant interest in solving high-resolution dynamic structures of membrane-associated peptides using solid-state NMR spectroscopy. Previous solid-state NMR studies have provided valuable insights into the functional properties of an exciting class of biomacromolecules such as antimicrobial peptides and am…
Abstract Glycidyl azide polymer (GAP) was cured through “click chemistry” by reaction of the azide group with bispropargyl succinate (BPS) through a 1,3‐dipolar cycloaddition reaction to form 1,2,3‐triazole network. The properties of GAP‐based triazole networks are compared with the urethane cured GAP‐systems. The gla…
Monoclinic α-Li 3 V 2 (PO 4 ) 3 has a complex 3-D metal phosphate framework that provides mobility for all three lithium ions, giving it the highest gravimetric capacity (197 mAh/g) of all the transition-metal phosphates. Along with its high gravimetric capacity, its thermal and electrochemical stability make it of gr…
Abstract The microstructures and granularity distribution of different metal particles were investigated and the energy, sensitivity, and combustion properties of fuel rich solid propellants with different metal particles were studied in detail. It was found that the magnesium particles are more uniform than other met…
This study describes a systematic approach of TiO2/carbon black nanoparticles with respect to the loading amount in order to optimize the catalytic ability of triiodide reduction for dye-sensitized solar cells. In particular, the cell using an optimized TiO2 and carbon black electrode presents an energy conversion eff…
Efficient delivery of stem cells to target tissues is a major problem in regenerative medicine. Adipose derived stem cells have been proposed as important tools in cell therapy for recovering tissues after damage. Nevertheless, the ability of these ASCs to migrate or invade in order to reach the tissue of interest has…
Kinetic Isotope effects (KIEs) have long served as a probe for the mechanisms of both enzymatic and solution reactions. Here, we discuss various models for the physical sources of KIEs, how experimentalists can use those models to interpret their data, and how the focus of traditional models has grown to a model that…
