Long-patch Base Excision Repair01:02

Long-patch Base Excision Repair

Since the discovery of the two BER pathways, there has been a debate about how a cell chooses one pathway over the other and the factors determining this selection. Numerous in vitro experiments have pointed out multiple determinants for the sub-pathway selection. These are:
Asymmetric Lipid Bilayer01:35

Asymmetric Lipid Bilayer

Biological membranes show uneven distribution of different types of lipids in the inner and outer layers, resulting in transverse asymmetric membranes. The treatment of the erythrocyte membrane with the enzyme phospholipase confirmed the asymmetric nature of the lipid bilayer. The enzyme hydrolyzes lipids into fatty acids and hydrophilic groups. The phospholipase acts only on the outer layer of the membrane, while the inner layer remains intact. The phospholipase treatment resulted in 80%...
Mechanisms of Membrane-bending01:15

Mechanisms of Membrane-bending

The living membranes are flexible due to their fluid mosaic nature; however, their bending into different shapes is an active process regulated by specific lipids and proteins. The membrane bending can be transient as seen in vesicles or stable for a long time as in microvilli. Cells regulate the size, location, and duration of the membrane curvature.
Membrane bending can happen due to intrinsic changes in lipid composition or extrinsic association with different proteins. The proteins involved...
Multi-pass Transmembrane Proteins and β-barrels01:09

Multi-pass Transmembrane Proteins and β-barrels

In multi-pass transmembrane proteins, the polypeptide chain crosses the membrane more than once. The transmembrane polypeptide chain either forms an α-helix or β-strand structure. α-Helix containing multi-pass transmembrane proteins are ubiquitous, whereas β-strand containing ones are mainly found in gram-negative bacteria, mitochondria, and chloroplasts.

Unsymmetric Bending01:18

Unsymmetric Bending

Unsymmetrical bending occurs when the bending moment applied to a structural member does not align with its principal axis. This misalignment leads to complex stress distributions and deflection patterns that differ from those in symmetrical bending, and are essential for designing structures to withstand different loading conditions. In unsymmetrical bending, the neutral axis—where stress is zero—does not necessarily align with the geometric axes of the cross-section. The orientation of the...
The Electrical Double Layer01:30

The Electrical Double Layer

In the region where two bulk phases meet, an intricate electric charge distribution arises due to charge transfer, ion adsorption, molecular orientation, and charge distortion. This complex distribution is commonly referred to as the electrical double layer.When a solid electrode interfaces with ions in an electrolyte solution, the speed of electron transfer dictates the rates of oxidation and reduction. The electrode acquires a charge through the escape of atoms into the solution as cations or...

Summary
This summary is machine-generated.

Marginally twisted tungsten disulfide (WS2) bilayers show lattice distortions. This study reveals the reconstruction is confined to one WS2 layer interacting with graphite, forming unique ferroelectric domain walls.

Area of Science:

  • Materials Science
  • Condensed Matter Physics
  • Nanotechnology

Background:

  • Marginally twisted bilayers of transition metal dichalcogenides, such as WS2, are known to exhibit lattice reconstructions.
  • The spatial distribution of these reconstructions within the individual sublayers of the bilayer remains poorly understood.

Purpose of the Study:

  • To investigate the sublayer-specific atomic and electronic properties of twisted WS2 bilayers.
  • To determine the location and nature of lattice reconstructions in these systems.

Main Methods:

  • Utilized in situ noncontact atomic force microscopy (nc-AFM) combined with scanning tunneling spectroscopy (STS).
  • Employed depth-tuning capabilities of the combined techniques to probe each sublayer independently.
  • Analyzed atomic lattice and electronic structure with sublayer resolution.

Main Results:

  • Observed a lattice reconstruction unexpectedly localized to the WS2 layer directly interfacing with the graphite substrate.
  • Demonstrated that transition metal dichalcogenide-substrate interactions are the primary drivers of this reconstruction.
  • Identified the formation of a novel type of ferroelectric domain wall.

Conclusions:

  • The lattice reconstruction in twisted WS2 bilayers is not uniformly distributed but is dictated by substrate interactions.
  • Sublayer-resolved probing is crucial for understanding complex structural phenomena in van der Waals heterostructures.
  • The findings open avenues for engineering ferroelectric properties in 2D materials.
