Quantum noise and its evasion in feedback oscillators
(Springer Science and Business Media LLC, 2023-11-04)
Feedback oscillators, consisting of an amplifier whose output is partially fed back to its input, provide stable references for standardization and synchronization. Notably, the laser is such an oscillator whose performance ...
Large magnetoelectric coupling in multiferroic oxide heterostructures assembled via epitaxial lift-off
(Springer Science and Business Media LLC, 2020-06-24)
Epitaxial films may be released from growth substrates and transferred to structurally and chemically incompatible substrates, but epitaxial films of transition metal perovskite oxides have not been transferred to electroactive ...
Flow-induced periodic chiral structures in an achiral nematic liquid crystal
(Springer Science and Business Media LLC, 2024-01-08)
Supramolecular chirality typically originates from either chiral molecular building blocks or external chiral stimuli. Generating chirality in achiral systems in the absence of a chiral input, however, is non-trivial and ...
Enhancing antibody responses by multivalent antigen display on thymus-independent DNA origami scaffolds
(Springer Science and Business Media LLC, 2024-01-30)
Protein-based virus-like particles (P-VLPs) are commonly used to spatially organize antigens and enhance humoral immunity through multivalent antigen display. However, P-VLPs are thymus-dependent antigens that are themselves ...
A sub-wavelength Si LED integrated in a CMOS platform
(Springer Science and Business Media LLC, 2023-02-16)
A nanoscale on-chip light source with high intensity is desired for various applications in integrated photonics systems. However, it is challenging to realize such an emitter using materials and fabrication processes ...
DNA nanopores as artificial membrane channels for bioprotonics
(Springer Science and Business Media LLC, 2023-09-04)
<jats:title>Abstract</jats:title><jats:p>Biological membrane channels mediate information exchange between cells and facilitate molecular recognition. While tuning the shape and function of membrane channels for precision ...
Switch of cell migration modes orchestrated by changes of three-dimensional lamellipodium structure and intracellular diffusion
(Springer Science and Business Media LLC, 2023-08-24)
<jats:title>Abstract</jats:title><jats:p>Cell migration plays important roles in many biological processes, but how migrating cells orchestrate intracellular molecules and subcellular structures to regulate their speed and ...
Nonlinear wave evolution with data-driven breaking
(Springer Science and Business Media LLC, 2022-04-29)
Wave breaking is the main mechanism that dissipates energy input into ocean waves by wind and transferred across the spectrum by nonlinearity. It determines the properties of a sea state and plays a crucial role in ...
Dynamic actuation enhances transport and extends therapeutic lifespan in an implantable drug delivery platform
(Springer Science and Business Media LLC, 2022-08-03)
Fibrous capsule (FC) formation, secondary to the foreign body response (FBR), impedes molecular transport and is detrimental to the long-term efficacy of implantable drug delivery devices, especially when tunable, temporal ...
Sequential metamaterials with alternating Poisson’s ratios
(Springer Science and Business Media LLC, 2022-02-24)
Mechanical metamaterials have been designed to achieve custom Poisson’s ratios via the deformation of their microarchitecture. These designs, however, have yet to achieve the capability of exhibiting Poisson’s ratios that ...
