Dual‐Ligand Metal‐Organic Frameworks via In Situ Amidoxime Engineering for Selective Ion Separation

open access: yesAdvanced Functional Materials, EarlyView.
Inspired by microbial ion‐trapping mechanisms, a mild and universal strategy is developed to construct highly porous amidoxime‐functionalized MOFs. DFT calculations and molecular force measurements reveal that the dual‐ligand amidoxime configuration significantly strengthens Ga(III) affinity.

A Crystalline Mono‐Coordinate Indium(I)‐Phosphaalkenyl

open access: yesAngewandte Chemie, EarlyView.
The redox neutral carbometallation of a phospha‐alkyne using the dimeric indium(I) compound (InTer)2 is reported. This reaction affords a mono‐coordinate indium(I) compound that can reversibly extrude the phospha‐alkyne upon addition of a Lewis acid. Abstract The synthesis of the mono‐coordinate indium(I) compound In[C(Ad)═PTer] (Ad = 1‐adamantyl, Ter =

Viscosity-temperature relationships in the system Na2Si2O5-Na4Al2O5 [PDF]

open access: yes, 1986
The viscosity-temperature relationships of five melts on the join Na2Si2O2-Na4Al2O5 (5, 10, 20, 30 and 40 mole percent Na4Al2O5) have been measured in air, at 1 atm and 1000–1350°C with a concentric cylinder viscometer.

A New Family of Ternary Intermetallic Compounds with Dualistic Atomic Ordering – The ZIP Phases

open access: yesAdvanced Materials, EarlyView.
The ZIP phases are ternary intermetallic compounds with dualistic atomic ordering, i.e., they exhibit one face‐centered cubic (fcc; space group Fd3¯$\bar 3$m) variant and one hexagonal (space group P63/mmc) variant. The ZIP phases in the Nb‐Si‐Ni system are the Nb3SiNi2 (fcc) and Ni3SiNb2 (hexagonal) ternary IMCs, crystal structure schematics of which ...

Photoelasticity of sodium silicate glass from first principles

open access: yes, 2004
Based on density-functional perturbation theory we have computed the photoelastic tensor of a model of sodium silicate glass of composition (Na$_2$O)$_{0.25}$(SiO$_2$)$_{0.75}$ (NS3).

Molecular Surface Engineering of Sulfide Electrolytes with Enhanced Humidity Tolerance for Robust Lithium Metal All‐Solid‐State Batteries

open access: yesAdvanced Materials, EarlyView.
It is demonstrated that the electrochemical, interfacial, and humidity stability of halide‐doped sulfide electrolytes (LPSClBr) is significantly enhanced by an organic surface coating using octadecyl phosphonic acid (OPA) and its lithiated form (Li‐OPA). This single‐step strategy enables robust interfacial protection, supports lithium metal anodes, and

Energy dependence of Normal Branch Oscillation in Scorpius X-1

open access: yes, 2012
We report the energy dependence of normal branch oscillations (NBOs) in Scorpius X-1, a low-mass X-ray binary Z-source. Three characteristic quantities (centroid frequency, quality factor, and fractional root-mean-squared (rms) amplitude) of a quasi ...

Simultaneous aluminum, silicon, and sodium coordination changes in 6 GPa sodium aluminosilicate glasses [PDF]

open access: yes, 2009
We present the first direct observation of high-coordinated Si and Al occurring together in a series of high-pressure sodium aluminosilicate glasses, quenched from melts at 6 GPa.

White Light Generation From YAG:Ce‐Doped Phosphate Glass‐Based Composite Fibers

open access: yesAdvanced Optical Materials, EarlyView.
The first white‐light‐emitting composite fiber based on YAG:Ce3+ phosphors in phosphate glass is developed. The glass composition is custom‐engineered to enhance thermal stability and to match YAG:Ce3+ refractive index, ensuring composite transparency.

Theoretical Study of Heteroatom Resonance-Assisted Hydrogen Bond: Effect of Substituent on π-delocalization [PDF]

open access: yesIranian Journal of Chemistry & Chemical Engineering, 2010
The concept of Resonance Assisted Hydrogen Bond (RAHB), which usually occurs in b diketons, has a remarkable role in chemistry. These molecules, which contain heteroatom particularly O and N, are species with biological interest in protein folding and ...
