Conservation of Protein Domains Over Different Proteins02:26

Conservation of Protein Domains Over Different Proteins

14.6K
Protein domains are small structurally independent units that are part of a single amino acid chain.  Although these domains are often structurally independent, they may rely on synergistic effects to perform their functions as part of a larger protein. Protein domains may be conserved within the same organism, as well as across different organisms.
A limited set of protein domains often duplicate and recombine during evolution. These domains can be organized in different combinations to...

Self-Evaluation: Self-Enhancement and Self-Verification

Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...

Plant Cell Wall02:43

Plant Cell Wall

60.5K
The plant cell wall gives plant cells shape, support, and protection. As a cell matures, its cell wall specializes according to the cell type. For example, the parenchyma cells of leaves possess only a thin, primary cell wall.

Membrane Domains01:18

Membrane Domains

7.2K
The membrane domains concentrate specific lipids and proteins at one place within the membrane, which helps in cell signaling, adhesion, and other critical cellular processes. These domains can differ in size, composition, function, and lifespan.
Protein Domains
The membrane comprises a group of distinct proteins responsible for carrying out a cell's specific function. For example, the plasma membrane of the human sperm, or a single germ cell, contains a unique set of proteins in the...

Three Developmental Domains01:29

Three Developmental Domains

1.1K
Human development is typically examined across three main domains: physical, cognitive, and socio-emotional. These domains represent the significant areas of change and continuity throughout the lifespan, from infancy to late adulthood.
Physical Development
Physical processes, also known as maturation, encompass the biological changes that occur across an individual's life. These changes begin with genetic inheritance and continue through various stages, including growth in height and weight,...

Area of Science:

  • Materials Science
  • Condensed Matter Physics
  • Electrical Engineering

Background:

  • Ferroelectric polarization and domain walls are crucial for electronic devices but traditionally cause high dielectric loss and hysteresis.
  • Existing tunable dielectrics often require operation above the ferroelectric Curie temperature or under piezoelectric resonance, compromising performance.
  • A trade-off exists between high tunability and low loss in current tunable dielectric devices, limiting their figure of merit.

Purpose of the Study:

  • To demonstrate that ferroelectric domain structures can be exploited for ultralow loss and exceptional frequency selectivity in microwave devices.
  • To overcome the limitations of traditional tunable dielectrics by utilizing domain wall properties.
  • To achieve gigahertz microwave tunability and low dielectric loss surpassing current state-of-the-art devices.

Main Methods:

  • Utilizing intrinsically tunable materials whose properties depend on nanometer-scale domain structures.
  • Investigating thermodynamically predicted strain-induced, ferroelectric domain-wall variants.
  • Measuring gigahertz microwave tunability and dielectric loss, and quality factors.

Main Results:

  • Achieved gigahertz microwave tunability and dielectric loss superior to film devices by one to two orders of magnitude.
  • Observed quality factors exceeding theoretical limits due to domain-wall fluctuations, not piezoelectric oscillations.
  • Demonstrated resonant frequency tuning across L, S, and C microwave bands (1-8 GHz) in a single device, a 100-fold increase in range.

Conclusions:

  • Ferroelectric domain structures can be leveraged to achieve ultralow loss and high frequency selectivity, overcoming previous device limitations.
  • The findings present a promising strategy for developing ultrahigh frequency agility and low-loss microwave devices.
  • Exploiting the phase space of nanometer-scale domain structures offers a new pathway for advanced electronic device design.
