The Dependency of Nematic and Twist-bend Mesophase Formation on Bend Angle [PDF]
Scientific Reports, 2016 AbstractWe have prepared and studied a family of cyanobiphenyl dimers with varying linking groups with a view to exploring how molecular structure dictates the stability of the nematic and twist-bend nematic mesophases. Using molecular modelling and 1D1H NOESY NMR spectroscopy, we determine the angle between the two aromatic core units for each dimer ...

Design and demonstration of an acoustic right-angle bend [PDF]
The Journal of the Acoustical Society of America, 2017 In this paper, a broadband acoustic right-angle bend device in air is designed, fabricated and experimentally characterized. Perforated panels with various hole-sizes are used to construct the bend structure. Both the simulated and experimental results verify that the acoustic beam can be rotated effectively through the acoustic bend in a wide ...

Right-angle slot waveguide bends with high bending efficiency
Optics Express, 2008 Two right-angle bends for nanoscale slot waveguides with high bending efficiency based on a corner mirror and different resonant cavities are presented, one with a triangular cavity and the other with a square cavity. Through two-dimensional parametric scanning of the position of the mirror and the dimension of the cavity, a maximum bending efficiency ...

Spring-back effect during multi-pass bending of sheet blanks [PDF]
E3S Web of Conferences, 2019 A significant factor, which leads to the discrepancy of the final sizes of the bent sheet parts to their drawings is the springing of the sheet blank during bending.

Mean DNA Bend Angle and Distribution of DNA Bend Angles in the CAP-DNA Complex in Solution
Journal of Molecular Biology, 2001 In order to define the mean DNA bend angle and distribution of DNA bend angles in the catabolite activator protein (CAP)-DNA complex in solution under standard transcription initiation conditions, we have performed nanosecond time-resolved fluorescence measurements quantifying energy transfer between a probe incorporated at a specific site in CAP, and ...

Role of molecular bend angle and biaxiality in the stabilization of the twist-bend nematic phase
Soft Matter, 2020 Within mean-field theory for V-shaped molecules, we have investigated how the alteration of a molecule's structural features influence the stabilization of modulated and non-modulated nematic phases.

Strategy to minimize bending strain interference for flexible acoustic wave sensing platform
npj Flexible Electronics, 2022 There are great concerns for sensing using flexible acoustic wave sensors and lab-on-a-chip, as mechanical strains will dramatically change the sensing signals (e.g., frequency) when they are bent during measurements.
