(1R*,2R*,5R*,6S*)-6-Bromo-9-oxabicyclo[3.3.1]nonan-2-ol

open access: yesIUCrData
Both six-membered rings in the title bicyclo[3.3.1] system, C8H13BrO2, adopt a chair conformation. Hydrogen bonds from the hydroxy group to the ether bridge connect the molecules into zigzag chains: single-enantiomer chains propagating along the b-axis ...

Spin and Charge Control of Topological End States in Chiral Graphene Nanoribbons on a 2D Ferromagnet

open access: yesAdvanced Materials, EarlyView.
Chiral graphene nanoribbons on a ferromagnetic gadolinium‐gold surface alloy display tunable spin and charge states at their termini. Atomic work function variations and exchange fields enabe transitions between singlet, doublet, and triplet configurations.

Hydrogeological uniqueness of groundwater in the Cherkashinsky area of the Tobolsk district of the Tyumen region

open access: yesИзвестия высших учебных заведений: Нефть и газ
Intensive development of the Tyumen region, where the largest West Siberian megabasin is located (the Tyumen groundwater deposit is the largest in Russia), violates the natural state of ecosystems, in particular groundwater, which is the basis of an ...

Bromine-Substituted Indolo[3,2‑b]carbazole-Based Small Organic Molecules as Dopant-Free Hole-Transporting Layers for Inverted Perovskite Solar Cells

open access: yes
In this paper, three indolo­[3,2-b]­carbazole-based small organic molecules (ICZ, ICZ-2Br, and ICZ-4Br) are rapidly synthesized and used as dopant-free hole transport layers (HTLs) for inverted perovskite solar cells.

Impact of Very Short-Lived Substances on Stratospheric Bromine Loading [PDF]

open access: yes, 2011
Recent studies have shown the importance of very short-lived substances (VSLS) for the abundance of stratospheric bromine. In this work, the transport of bromine VSLS into the stratosphere is investigated with a three-dimensional chemistry transport ...

Flexible Dielectric Acoustic Resonator Patch for Tissue Regeneration

open access: yesAdvanced Materials, EarlyView.
A flexible dielectric acoustic resonator patch enables MHz‐range ultrasound generation through resonance amplification without using piezoelectric materials. Conformal integration on a curved substrate allows efficient acoustic delivery to tissue‐mimicking environments.

Demo 16-11 Bromine Diffusion

open access: yes, 2001
Any molecule interacts with the surrounding air molecules as it diffuses through the air, limiting the speed with which it diffuses. Conversely, the molecules will diffuse through a partially evacuated tube at a much faster speed.

Ion‐Reconfigurable “N”‐Shaped Antiambipolar Behavior in Organic Electrochemical Transistors

open access: yesAdvanced Materials, EarlyView.
A unique N‐shaped negative differential transconductance (NDT) characteristics is demonstrated in single‐polymer organic electrochemical transistors through a sequential doping–redox–doping process driven by iodide ions. This redox‐driven mechanism enables low‐voltage, ion‐controlled reconfigurability and tunable current modulation, allowing seamless ...

Anomalous halogen bonds in the crystal structures of 1,2,3-tribromo-5-nitrobenzene and 1,3-dibromo-2-iodo-5-nitrobenzene

open access: yesActa Crystallographica Section E: Crystallographic Communications, 2015
The title trihalogenated nitrobenzene derivatives, C6H2Br3NO2 and C6H2Br2INO2, crystallize in triclinic and monoclinic cells, respectively, with two molecules per asymmetric unit in each case.

One‐Dimensional Materials Supported in Two‐Dimensional Van der Waals Metal–Organic Frameworks with Optical Anisotropy Switching via Twist‐Engineering

open access: yesAdvanced Materials, EarlyView.
We introduce a molecular strategy to assemble one‐dimensional (1D) materials into two‐dimensional (2D) van der Waals metal–organic frameworks (MOFs). Crystals of [FeX(pzX)(bpy)] (X = Cl, F) form anisotropic 2D layers that can be mechanically exfoliated into thin sheets.
