Recent investigations on the design and application of liquid crystal-based biosensors have been reviewed, according to phenomenon that orientations crystals can be directly influenced by interactions between biomolecules crystal molecules. With ability detect external stimuli with high sensitivity, help realize a new biosensing era.

Germanium nanowires have been grown successfully on titanium. The wires are single crystal, with some low angle stacking faults and other defects. Growth of nanowires on metal substrates offers reduced cost over single crystal substrates, while still offering an electrical contact to the wire core for core-shell junction structures. Summary of Research: Figure 1: 80 nm germanium nanowires on a ...

In the southwest U.S., cracks in alluvial fan surface clasts have a preferred orientation independent of rock fabric and shape. In this paper, we show that differential insolation of incipient cracks of random orientations predicts a distribution of crack orientations consistent with field observations. In this model, crack growth by hydration and/ or thermal weathering is primarily a function ...

The acetylene-oxygen combustion flame technique was applied to the homoepitaxial deposition of diamond single crystals on cylindrically shaped {111}, {001} and {110} type IIa natural diamond substrates. After deposition the specimen revealed surface stabilization phenomena like flat facets and curved bands for orientations corresponding to Miller indices {hhk}h < k in the (110) zones. The surfa...

Neurons in the visual cortex respond best to rod-like stimuli of given orientation. While the preferred orientation varies continuously across most of the cortex, there are prominent pinwheel centers around which all orientations are present. Oriented segments abound in natural images and tend to be collinear; neurons are also more likely to be connected if their preferred orientations are alig...

Characterizing and controlling the interlayer orientations and stacking orders of two-dimensional (2D) bilayer crystals and van der Waals (vdW) heterostructures is crucial to optimize their electrical and optoelectronic properties. The four polymorphs of layered gallium selenide (GaSe) crystals that result from different layer stackings provide an ideal platform to study the stacking configurat...

The behavior of water molecules inside and outside 1.1, 2.8, 6.9, and 10.4 nm diameter armchair carbon nanotubes (CNTs) is predicted using molecular dynamics simulations. The effects of CNT diameter on mass density, molecular distribution, and molecular orientation are identified for both the confined and unconfined fluids. Within 1 nm of the CNT surface, unconfined water molecules assume a spa...

The tilt aftereffect (TAE) is a visual illusion in which prolonged adaptation to an oriented stimulus causes shifts in subsequent perceived orientations. Historically, neural models of the TAE have explained it as the outcome of response suppression of neurons tuned to the adapting orientation. Recent physiological studies of neurons in primary visual cortex (V1) have confirmed that such respon...

Deformation mechanisms of as-deposited and post-annealed Ti50.2Ni49.6, Ti50.3Ni46.2Cu3.5 and Ti48.5Ni40.8Cu7.5 thin films were investigated using the in situ synchrotron X-ray diffraction technique. Results showed that initial crystalline phases determined the deformation mechanisms of all the films during tensile loading. For the films dominated by monoclinic martensites (B19'), tensile stress...
