Abstract Small‐molecule drugs often have limited solubility, display rapid clearance or poor selectivity that leads to undesired side‐effects. Although prodrug strategies can improve solubility and lower toxicity, activation ‘on demand’ as well as targeted transport of prodrugs remains a challenge in drug delivery. Re…
A well crystallized Benzophenone single crystal was successfully grown by vertical semi transparent Bridgman technique. The lattice parameters of the grown crystal were established by single crystal x-ray diffraction technique. Fourier transform infrared spectroscopy was performed to determine the functional groups. T…
Large quantities of waste slags are produced during the preparation of electrical manganese, causing serious pollution to the environment. The recycling and utilization of electrolytic manganese slag (EMS) is a serious challenge to the industry. Here, we report the utilization of EMS in preparation of high-performance…
Controlling self-assembled nanostructures in thin films allows the bottom-up fabrication of ordered nanoscale patterns. Here we report the unique thickness-dependent phase behavior in thin films of a bolaform-like giant surfactant, which consists of butyl- and hydroxyl-functionalized polyhedral oligomeric silsesquioxa…
Defect perovskites (He 2– x □ x )(CaZr)F 6 can be prepared by inserting helium into CaZrF 6 at high pressure. They can be recovered to ambient pressure at low temperature. There are no prior examples of perovskites with noble gases on the A-sites. The insertion of helium gas into CaZrF 6 both elastically stiffens the…
Significant developments have been proposed over the past decade in the synthesis of aluminosilicate and aluminogermanate imogolite-like nanotubes. But, while liquid phase synthesis is well-controlled, it is not the case for the nanotube arrangement in the dry state. In particular, nanotubes are found to self-assemble…
Abstract We have designed and developed a tetraphenylethen (TPE)‐anthracene‐(aminomethyl)phenylboronic acid ester (AminoMePhenylBPin) structure RN‐1 possessing PET (photo‐induced electron transfer) and AIEE (aggregation‐induced emission enhancement) characteristics as a fluorescent sensor for detection of water in org…
In this paper, epoxy-based shape-memory liquid-crystalline lightly cross-linked networks (LCN) are synthesized and characterized with a view to the future development of two-way autonomous shape-memory actuators by coupling the LCN with an external epoxy-matrix. Carboxylic acids of different aliphatic chain lengths ar…
We extend our finite-element model of nucleation, growth, and amorphization in phase-change memory devices to model discrete nucleation and grain boundaries, including the evolution of grains within fully crystalline material during long-term anneals. Electrothermal simulations of set and reset operations include a he…
Abstract The heterobimetallic complexes [Cu( phen )(NC 5 H 4 HC=NC 6 H 4 C≡CC 6 H 4 C≡CRu(dppe) 2 Cl)]X ( 1 a‐4 a ) and [Cu( bipy )(NC 5 H 4 H C=NC 6 H 4 C≡CC 6 H 4 C≡CRu(dppe) 2 Cl)]X ( 1 b‐4 b ) (where X= I, ClO 4 , BF 4 , PF 6 ; phen= 1, 10 phenanthroline, bipy = 2, 2′ bipyridine) have been prepared by the reaction…
CoCrMo alloy has become one of the most important load-bearing materials in orthopedics. The influence of alloying components on the alloy’s electrochemical behavior (passivity, pitting corrosion, and transpassivity) has been investigated in situ under in vitro conditions in Hanks’ solution. It was shown that anodic o…
The present work is conducted to study the microstructure and texture evolutions in an as‐cast A206 aluminum alloy after applying severe plastic deformation. Toward this end, the material is severely deformed through accumulative back extrusion (ABE) technique at 200 °C and followed by assessing the room temperature m…
Hydrogen-bonded β-sheets are the most commonly explored building motifs for creating peptide-based filamentous nanostructures; however, most bioactive epitopes must assume an α-helix conformation to exert their functions. Incorporating α-helical sequences into β-sheet-forming peptides often involves the use of a flexi…
Abstract A series of novel multi‐arm azide copolymers (POGs) with the same hyperbranched poly[3‐ethyl‐3‐(hydroxymethyl)oxetane] core (PEHO‐ c ) and different content of linear glycidyl azide polymer shell (GAP‐ s ) have been synthesized by sequential cationic ring‐opening polymerization and azidation. Detailed structu…

The aggregation of intrinsically disordered and misfolded proteins in the form of oligomers and fibrils plays a crucial role in a number of neurological and neurodegenerative diseases. Currently, most probes and biophysical techniques that detect and characterize fibrils at high resolution fail to show sensitivity and…
Two systems of suspended nanoparticles have been studied with near-ambient pressure x-ray photoelectron spectroscopy: silver nanoparticles in water and strontium fluoride-calcium fluoride core-shell nanoparticles in ethylene glycol. The corresponding dry samples were measured under ultra high vacuum for comparison. Th…
Abstract Recent studies of single-molecule thermoelectricity have identified families of high-performance molecules. However, in order to translate this discovery into practical thin-film energy-harvesting devices, there is a need for an understanding of the fundamental issues arising when such junctions are placed in…
Abstract Infrared photodissociation spectroscopy of mass‐selected heteronuclear cluster anions in the form of OMFe(CO) 5 − (M=Sc, Y, La) indicates that all these anions involve an 18‐electron [Fe(CO) 4 ] 2− building block that is bonded with the M center through two bridged carbonyl ligands. The OLaFe(CO) 5 − anion is…
In this paper, we propose the design of an optical device that is able to selectively absorb impinging light in a desired frequency range while being almost completely transparent outside this range. The proposed absorber is a variant of the optical Salisbury screen we recently proposed [Opt. Lett.41, 3383 (2016)OPLED…
