Recent progress in the development of barium strontium titanate thin film varactors for room temperature tunable microwave devices applications is reviewed, with emphasis on efforts towards improvement quality BST films and fabrication issues crucial performance based varactors. The paper provides examples employing Other materials currently competing are discussed. Topics which deserve further investigation suggested.
The dielectric property complemented by the mechanical measurement (internal friction) in doped Bi4Ti3O12 [Bi4−xLaxTi3O12 (x=0.5,0.75,1) and Bi4−y/3Ti3−yNbyO12 (y=0.015,0.03,0.06)] was systematically investigated from room temperature to 350 °C. In plot of loss versus for (BiT), a relaxation peak confirmed be associated with motion oxygen vacancy. It is found that La doping at site A favor improvement fatigue property, contrast, Nb B can mainly enhance remanent polarization. Appropriate...
The recruitment of signaling proteins into activated receptor tyrosine kinases (RTKs) to produce rapid, high-fidelity downstream response is exposed the ambiguity random diffusion target site. Liquid-liquid phase separation (LLPS) overcomes this by providing elevated, localized concentrations required while impeding competitor ligands. Here, we show a subset phosphorylation-dependent RTK-mediated LLPS states. We then investigate formation phase-separated droplets comprising ternary complex...
Lipid coated liquid crystal droplets have been trapped in a novel trap structure for the on-chip detection of model antimicrobial peptide – Smp43, an α-helical from Scorpion Venom.
Abstract Interrogating individual molecules within bio-membranes is key to deepening our understanding of biological processes essential for life. Using Raman spectroscopy map molecular vibrations ideal non-destructively ‘fingerprint’ biomolecules dynamic information on their structure, composition and conformation. Such tag-free tracking lipid can directly connect structure function. In this paper, stable co-assembly with gold nano-components in a ‘nanoparticle-on-mirror’ geometry strongly...
For a series of phospholipid coated calamitic nematic liquid crystal droplets (5CB, 6CB, 7CB, E7 and MLC7023) diameter ∼18 μm, the addition chiral dopant leaves sign surface anchoring unchanged. Herein we report that for these an analyte induced transition from Frank-Pryce structure (with planar anchoring) to nested-cup perpendicular is accompanied by changes in intensity reflected light. We propose this system as both general scheme understanding director fields with ideal candidate be...
Due to their graphene-like properties after oxygen reduction, incorporation of graphene oxide (GO) sheets into correlated-electron materials offers a new pathway for tailoring properties. Fabricating GO nanocomposites with polycrystalline MgB2 superconductors leads an order magnitude enhancement the supercurrent at 5 K/8 T and 20 K/4 T. Herein, we introduce novel experimental approach overcome formidable challenge performing quantitative microscopy microanalysis such composites, so as unveil...

We describe a modified microfluidic method for making Giant Unilamellar Vesicles (GUVs) via water/octanol-lipid/water double emulsion droplets. At high enough lipid concentration we show that the de-wetting of octanol from these droplets occurs spontaneously (off-chip) without need to use shear aid process. The resultant mixture and GUVs can be separated by buoyancy octanol. A simpler device pump system employed and, because higher flow-rates much rate formation (∼1500 s-1 compared up ∼75...
Abstract A range of triphenylene and phthalocyanine‐based discotic liquid crystals (DLCs) can be aligned within micrometer‐scale channels formed from SU8 patterned on silicon or glass surfaces. The filled with the DLC in its isotropic phase using capillary action. Alignment occurs spontaneously as sample is slowly cooled into Col h phase. Whilst all these DLCs align columns perpendicular to surface when they are ‘sandwiched’ between slides, channels, aligns column director parallel surface....
This study presents a direct comparison between semiconductor and barium strontium titanate (BST) tuning technologies. Tapped line combline two-pole four-pole bandpass filters were designed in coplanar waveguide configuration. Discrete BST interdigital capacitors fabricated integrated into the filter circuits hybrid manner.

Poly(2-dimethylamino)ethyl methacrylate) (PDMA) brushes are grown from planar substrates via surface atom transfer radical polymerization (ATRP). Quaternization of these is conducted using 1-iodooctadecane in n-hexane, which a non-solvent for PDMA. Ellipsometry, AFM, and water contact angle measurements show that surface-confined quaternization occurs under conditions, producing pH-responsive have hydrophobic upper surface. Systematic variation the concentration reaction time enables mean...
In liquid crystal (LC) droplets, small changes in surface anchoring energy can produce large the director field which result readily detectable optical effects. This makes them attractive for use as biosensors. Coating LC droplets with a phospholipid monolayer provides bridge between hydrophobic world of LCs and water-based biology it possible to incorporate naturally occurring biosensor systems. However, phospholipids promote strong perpendicular (homeotropic) that inhibit switching field....

We obtain lateral photovoltaic effect maximum sensitivity 308.3 mV/mm, which very large value in the field organic materials, even comparable reported sensitivities most inorganic materials. attribute...
In probability theory, there is a counter-intuitive result that it possible to construct winning strategy from two individually losing (or at most breaking-even) “games” by alternating between them. The work presented here demonstrates the application of this principle supported lipid bilayers (SLBs) in order create directed motion charged components membrane, which was achieved through use “Brownian ratchets” patterned SLBs. Both finite element analysis model and an experimental setup have...
