Source: Sina Shahbazmohamadi and Peiman Shahbeigi-Roodposhti-Roodposhti, School of Engineering, University of Connecticut, Storrs, CT
Alloys with grain size less than 100 nm are known as nanocrystaline alloys. Due to their enhanced physical and mechanical properties, there is an ever-increasing demand to employ them in various industries such as semiconductor, biosensors and aerospace. 
To improve the processing and application of nanocrystalline alloys, it is necessary to develop close to...

Intrinsically Disordered Proteins

19.2K
Intrinsically disordered proteins are a group of proteins that do not fold into specific three-dimensional structures. Their structural flexibility allows them to complement ordered proteins to perform functions that are inaccessible to rigid structures. They are more common in eukaryotes than prokaryotes and may either be exclusively intrinsically disordered or hybrid proteins, consisting of a mix of ordered and disordered regions. The absence of a rigid structure in these proteins can be...

Mapping the Structure-Function Relationships of Disordered Oncogenic Transcription Factors Using Transcriptomic Analysis

3.1K
Intrinsically disordered domains are important for oncogenic fusion transcription factor function. To therapeutically target these proteins, a more detailed understanding of the regulatory mechanisms employed by these domains is required. Here, we use transcriptomics to map important structural features of the intrinsically disordered EWS domain in Ewing...

Area of Science:

  • Surface Science
  • Atmospheric Chemistry
  • Spectroscopy

Background:

  • Understanding ice surface structure and dynamics is vital for atmospheric catalytic reactions.
  • Nanoscale ice structures play a role in upper atmospheric phenomena like polar mesospheric clouds.

Purpose of the Study:

  • To investigate the structural disorder of nanoscale ice islands.
  • To understand how island size affects ice surface properties and dynamics.
  • To provide insights into ice particle behavior in the upper atmosphere.

Main Methods:

  • Heterodyne-detected vibrational sum-frequency generation (HD-VSFG) spectroscopy.
  • Growth of isotopically diluted HOD crystalline ice films on Rh(111) under ultrahigh vacuum.
  • Controlled variation of ice film thickness to study nanoscale island effects.

Main Results:

  • Observed enhanced structural disorder at the nanoscale ice island surface, increasing with smaller terrace sizes.
  • Bipolar line shape in the Imχ(2) spectrum indicates hydrogen bond length alternation.
  • Increased peak splitting and bandwidth with decreasing film thickness suggest greater disorder.
  • Enhanced thermal expansivity of the top ice layer with decreasing island size.
  • Systematic blue shift of the dangling OD band with increasing temperature for smaller ice islands.

Conclusions:

  • Decreasing ice island size significantly enhances surface structural disorder and anharmonicity.
  • These findings offer valuable insights into the properties of ice particles in the upper atmosphere.
  • The study highlights the unique behavior of nanoscale ice surfaces compared to bulk ice.
