Short-chain analogues of N, N ′, N ″-tris-(4-alkylphenyl)-1,3,5-benzenetricarboxamide derivatives (methyl to butyl) are prepared, and their gelation study renders a positive result for all, except the butyl derivative, in both DMSO and DMSO/H 2 O. The crystal structure analysis of the parent compound ( 1a ) and its me…
A key open question in the glass transition field is whether a finite temperature thermodynamic transition to the glass state exists or not. Recent simulations of coupled replicas in atomistic models have found signatures of a static transition as a function of replica coupling. This can be viewed as evidence of an as…
Equations are deduced to describe the critical coupling condition to achieve perfect absorption for the thin-film absorbers of absorbing layer/spacer layer/substrate. By numerically solving these equations, a linear inequality is obtained to describe key characteristics of the absorbing layer needed for perfect absorp…
A four-primary liquid crystal display (LCD) by hybrid color processing in spatial and temporal domains is presented. By integrating with quantum dots, the number of LED can be reduced and the emission spectrum optimized. This approach exhibits following advantages over conventional three-primary LCDs: 1) it has 1.5X h…
Mg0.2Zn0.8O/metal nanoparticle systems have been fabricated and investigated. The photoluminescence results indicate that Al and Au nanoparticles could slightly enhance the near-band-edge (NBE) emission from Mg0.2Zn0.8O. In contrast, a giant and tunable NBE emission enhancement could be induced by Ag nanoparticles bas…
Fiber random arrangement in the yarn exerts considerable influence on yarn properties, such as yarn irregularity. In this study, fiber random arrangement in the yarn was simulated to form a yarn segment with a given length according to the uniform distribution of the positions of fiber left heads along yarn axis. Irre…
We demonstrated that SnO is oxidized to SnO2 in boiling water. (001)-oriented SnO thin films were pulsed-laser deposited onto a glass substrate. The Sn valence number changed from (II) to (IV) by keeping SnO films in boiling water at atmospheric pressure for 5 h. Optical transparency of the obtained SnO2 films was gre…
The nature of the large magnetostriction in body-centered Fe-based solid solutions has been widely discussed in the literature. Here, we use a combination of magnetostriction, magnetization, torque, and transmission electron microscopy measurements of specially annealed Co65Fe35 to show that the magnetostriction is ca…
The prostate-specific membrane antigen (PSMA) is an established target for the delivery of cancer therapeutic and imaging agents due to its high expression on the surface of prostate cancer cells and within the neovasculature of other solid tumors. Here, we describe the synthesis and screening of antibody-conjugated s…
The alkali fullerides, A(3)C(60) (A = alkali metal) are molecular superconductors that undergo a transition to a magnetic Mott-insulating state at large lattice parameters. However, although the size and the symmetry of the superconducting gap, Δ, are both crucial for the understanding of the pairing mechanism, they a…
The last few years have witnessed rapid development of highly ordered and reproducible surface‐enhanced Raman scattering (SERS) nanostructured substrates for their potential medical and analytical application such as biosensing and bioimaging. In this work, 5‐nm silver films deposited on nanostructured Al and Al2O3 te…
Abstract Während catena‐Phosphorkationen innerhalb der letzten Jahre intensiv untersucht wurden, gab es über gemischte kationische Ketten aus Gruppe‐13‐ und Gruppe‐15‐Elementen bislang keine Berichte. Die Umsetzung der Pnictogenborane H2EBH2⋅NMe3 (E=P, As) mit Monohalogenboranen führt zu den kationischen Kettenverbind…
Abstract RA110 is a computationally designed retro‐aldolase enzyme that utilizes amine catalysis to convert 4‐hydroxy‐4‐(6‐methoxy‐2‐naphthyl)‐2‐butanone to 6‐methoxy‐2‐naphthaldehyde and acetone. The original design accelerated substrate cleavage by a factor of 12 000 over background, and its activity was subsequentl…
Poly(amidoamine) (PAMAM) dendrimers play an important role in drug delivery systems, because the dendrimers are susceptible to gain unique features with modification of their structure such as changing their terminals or improving their interior core. To investigate the core improvement and the effect of core nature o…
The magnetic energy harvesting properties of piezoelectric bimorph/magnet composite are studied in this Letter. The devices are fabricated with NdFeB magnets and piezofiber (d33 mode), whose magnetoelectric (ME) coefficient reaches 526 V/cm·Oe (RMS) at the resonant frequency (27.3 Hz), and the maximum power density of…
Ru-aqua complex {[Ru(II)(trpy)(H2O)]2(μ-pyr-dc)}(+) is a powerful epoxidation catalyst for a wide range of linear and cyclic alkenes. High turnover numbers (TNs), up to 17000, and turnover frequencies (TOF), up to 24120 h(-1) (6.7 s(-1)), have been obtained using PhIO as oxidant. This species presents an outstanding s…
We have studied the correlation between the broadening of the isothermal magnetic entropy change and the Curie temperature (TC) distribution in nanostructured Pr2Fe17 and Nd2Fe17 alloys produced by high-energy ball-milling after milling times of 10, 20, and 40 h. The changes in the microstructure affect the Fe local e…
Laser irradiation of randomly oriented multi-walled carbon nanotube (MWCNT) networks has been carried out using a pulsed Nd:YAG UV laser in nitrogen gas environment. The evolution of the MWCNT morphology and structure as a function of laser fluence and number of accumulated laser pulses has been studied using electron…
Abstract A novel, simple, and efficient method for the preparation of the fluorinated hexagonal boron nitride nanosheets (F‐BNNSs) and the corresponding magnetic properties is presented. A one‐step route is used to exfoliate and fluorinate the BNNSs by ammonium fluoride (NH4F) from hexagonal boron nitride (h‐BN) powde…
The increasing morbidity and mortality of infectious diseases is an increasing concern. Despite the continuous development and synthesis of new antimicrobial drugs, microbial pathogens are exhibiting increased multi-drug resistance. Nanomaterials display unique and well-defined physical and chemical properties includi…
