Luminescence Vapochromism of a Cu(I)/Na Phosphane Iodide Assembly Based on a Secondary‐Sphere Sodium Response

open access: yesAngewandte Chemie, EarlyView.
The luminescence of a heterometallic d‐s {Cu2I2Na2} phosphane‐phosphinate aggregate is regulated by an interplay of Na+–π/I– contacts and reversible coordination of oxygen‐containing organic molecules to Na ions. Structural variations caused by the incoming guest lead to a wide and selective variation of the emission color and illustrate a new approach

Designing Wire Mazes for Replicating Natural Echoes to Study Bat Biosonar Function

open access: yesAdvanced Intelligent Systems, EarlyView.
A validated framework combining efficient physical modeling (multiple scattering model) and deep learning is presented to guide wire‐maze design for bat biosonar studies. This approach rapidly generates large datasets to test acoustic distinguishability among wire arrangements.

Conformationally Switchable Copper(I) Complexes Amplify BODIPY Triplet Photosensitization

open access: yesAngewandte Chemie, EarlyView.
Coupling a structurally switchable Cu(I) complex to an organic light‐harvesting chromophore boosts photoinduced intersystem crossing via the transient formation of a Cu(II) intermediate. Spectroscopic, physical, computational, and photocatalytic studies support this unique new approach to solar energy upconversion.

Objectives and Key Results–Driven Multiagent Framework for Mechanical Design and Simulation

open access: yesAdvanced Intelligent Systems, EarlyView.
Objectives and key results (OKR)‐agent, an OKR‐driven multiagent framework, turns a plain‐language engineering goal into completed mechanical simulations. Three peer agents—supervisor, modeler, and simulator—share a compact board of OKR and coordinate external molecular dynamics (MD) and finite‐element solvers through a standardized tool interface. The

Syntheses, X‐ray Crystal Structures, and Raman Spectra of Self‐Assembled XeO3 Chain and Network Complexes of Polytopic sp2‐ and sp3‐Nitrogen Bases

open access: yesAngewandte Chemie, EarlyView.
Supramolecular 1‐D, 2‐D, and 3‐D networks comprised of ‐(‐O═Xe(O2)‐‐)‐∞ and ‐(‐Xe(O2)O‐‐‐HO(H)‐‐)‐∞ chains coordinated to polytopic N‐base ligands were synthesized and structurally characterized by X‐ray crystallography. Their Xe‐‐‐N and Xe‐‐‐O bonds are characteristic of σ–hole bonds in which the nucleophilic Lewis base sites of the N‐ligands, H2O ...

Freedom dreaming of migrant justice: Critical reflections on counterspaces and institutional violence in the university

open access: yesAmerican Journal of Community Psychology, EarlyView.
Abstract US universities are built on stolen land and sustained through hierarchies of power that produce what migrant justice scholars name as b/order regimes. As institutions that claim to be sites of learning and inclusion, universities are fraught with contradictions as simultaneously sites of dispossession, exclusion, and control.

Partitioning behavior of the noble gases: Exploring the roles of sea-ice growth rate, temperature, salinity and brine porosity

open access: yesJournal of Glaciology
Sea ice develops a porous structure as impurities from sea water are rejected during freezing. This study revisits factors regulating noble gas inclusion in sea ice and, for the first time, parameterizes the bulk sea ice–sea water partition coefficient ...

Investigation on Electron Energy Distribution in Multi- Component Plasma in Nuclear Fuel Rod Gap [PDF]

open access: yesمجله علوم و فنون هسته‌ای, 2014
The electron energy distribution function in fuel rod gap of Busheher’s VVER-1000 nuclear reactor was investigated using the Fokker-Planck equation. In this regard, the Fokker-Planck equation was solved by using the Runge-Kutta numerical method, and the ...

Characterization of a Fungal Modular Polyketide Synthase System Reveals an Unusual Strategy for Polyketide Chain Initiation

open access: yesAngewandte Chemie, EarlyView.
Fungal modular polyketide synthases (PKSs) remain largely unexplored. Functional characterization of the LasC/LasD assembly line established its role in strasseriolide C biosynthesis and suggested an unexpected strategy for chain initiation, in which a malonyl unit is transferred from the module 2 acyl carrier protein (ACP) domains to the loading ACP ...

The mechanism of domain-wall structure formation in Ar-Kr submonolayer films on graphite

open access: yesCondensed Matter Physics, 2014
Using Monte Carlo simulation method in the canonical ensemble, we have studied the commensurate-incommensurate transition in two-dimensional finite mixed clusters of Ar and Kr adsorbed on graphite basal plane at low temperatures. It has been demonstrated
