A flexible 4 × sensor array with 16 micro-scale capacitive units has been demonstrated based on piezoelectric poly(vinylidene fluoride) (PVDF) film. The piezoelectricity and surface morphology of the PVDF were examined by optical imaging piezoresponse force microscopy (PFM). PFM shows phase contrast, indicating clear interface between electrode. electro-mechanical properties show that exhibits excellent output response an ultra-high signal-to-noise ratio. voltage applied pressure possess...

The space-time wave packet (STWP) is a type of pulsed optical field, exhibiting distinctive characteristics, including the capacity to propagate without diffraction or dispersion and have arbitrary group velocities. However, intensity STWP constrained by low damage threshold some indispensable elements like spatial light modulator (SLM). While parametric amplification (OPA) has been proposed for amplifying STWPs, spatio-temporal (ST) characteristics amplified STWPs remain significantly...

Bacterial phytochromes are attractive molecular templates for engineering fluorescent proteins (FPs) because their near-infrared (NIR) emission significantly extends the spectral coverage of GFP-like FPs. Existing phytochrome-based FPs covalently bind heme-derived tetrapyrrole chromophores and exhibit constitutive fluorescence. Here we introduce Rep-miRFP, an NIR imaging probe derived from bacterial phytochrome, which interacts non-covalently reversibly with biliverdin chromophore. In...

This paper answers a question that was raised from our recent work [1] for the non-standard single-edge notched bend (SE(B)) specimens, which exhibited test specimen thickness effect on Jc (TST Jc) together with bounded nature increasing TST in ductile-to-brittle transition temperature region. The "what is loss of constraint Jc, because crack opening stress σ22 distribution scaled CTOD at fracture load approximately same different TSTs?" To answer this question, several well-known parameters...

Abstract Moisture is of vital importance in starch modification; however, the molecular interaction between water and during process far from being fully understood. In this study, two fundamental issues esterification by solvent‐free method are focused on: 1) effect moisture content on modification 2) physical state, solid or liquid, chemical agents. The corn with varying contents (2.69–23.48 wt%) investigated method, using both (maleic anhydride maleic acid) liquid (acetic acetic...

Multiscale virtual environments (MSVEs) allow the integration of elements and at different scale levels into a unified space, which facilitates researchers’ perception, understanding, experimental research complex geospatial spaces. Although there have been several methods for achieving multiscale effects in (VEs), they cannot assist users constructing more complete spatial cognitive maps presenting information efficiently. This study proposes hierarchical-structure-based MSVE construction...

Radio-frequency (RF) performance of multi-finger partially depleted silicon-on-insulator (SoI) nMOSFETs with tunnel diode body contact (TDBC) structure is investigated in this letter. The TDBC suppresses floating-body effect and instability significantly shows less drain conductance degradation respect to FB TB devices. peak cutoff frequency (fT) maximum oscillation (fMAX) devices are 96.4 132.8 GHz, respectively. Due lower parasitic resistances capacitances, the device structures represents...
