Directional liquid transport has been widely observed in various species including cacti, spiders, lizards, the pitcher plant
The atomic and electronic structures of the black phosphorus surface are investigated by means scanning tunneling microscopy (STM) combined with density functional theory (DFT) calculations for first time. STM measurements reveal that atoms on occupy almost same sites they would have in bulk, except a little relaxation perpendicular to surface, which causes take two types positions (P1 P2) contrast visible images. DFT indicate small difference height 0.02 Å between at P1 P2 position breaks...
We use low energy electron diffraction, scanning tunneling microscopy, first-principles density-functional theory, and molecular mechanics calculations to analyze the adsorption growth of quinacridone derivatives (QA) with alkyl chains 4 16 carbon atoms on a Ag(110) substrate. Surprisingly, we find that determine orientation overlayers. While interaction QA Ag substrate is primarily due chemical bonding oxygen silver substrate, determining preferred site, intermolecular arrangement can be...
Self-assembly of manganese phthalocyanine (MnPc) and iron (FePc) molecules on Pb(111) Au(111) surfaces is investigated by means low-temperature scanning tunneling microscopy density functional theory calculations. Both metal (MPc) form ordered close-packed islands with different detail superstructures. In contrast, dispersive single are observed for both MPc Au(111). The self-assembling behaviors originate from a subtle balance between molecule–molecule molecule–substrate interactions tuned...
Double-sided insulated gate bipolar transistor (IGBT) assemblies bonded by sintered nanosilver are fabricated in this paper. Die-shear tests reveal that the lowest bonding strength between chip and substrate of is about 20 MPa. Furthermore, temperature cycling ( -40 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">°</sup> C to 150 C) indicate shear declines as number cycles increases. In addition, X-ray photographs show increasing size voids. The...
This study evaluates the contouring variability among observers using MR images reconstructed by different sequences and quantifies differences of automatic segmentation models for sequences. Eighty-three patients with pelvic tumors underwent T1-weighted image (T1WI), contrast enhanced Dixon (T1dixonc), T2-weighted (T2WI) imaging on a simulator. Two performed manual delineation bladder, anal canal, rectum, femoral heads all images. Contour were used to analyze interobserver intersequence...
Liquid manipulation is ubiquitous in nature and engineering, enabling controllable efficient liquid delivery. Conventional understanding of relies on inhomogeneous chemical modifications or single-scale structure design. Here, we present how water directionally navigated spontaneously reallocated at high efficiency via the cross-scale topology Tillandsia capitata leaves. These leaves feature transversely curved lanceolate macrostructures decorated by a layer microtrichomes with varied...
We have used low-temperature scanning tunneling spectroscopy to spatially map the energy-resolved electron density of a single Pb adatom on Pb(111) surface. observe clear spatial inhomogeneity spectral adatom. This is rotated with bias voltage, reflecting modification structure and symmetry orbitals by substrate. The simulated maps based density-functional-theory calculations agree well experimental observations. originates from local extension antibonding states coupling
The adsorption of N2O on the surface MgO(001) thin films has been studied at low temperature (60 K) using infrared reflection−absorption spectroscopy (IRAS) and temperature-programmed desorption (TPD). observed spectrum consists several components indicating different sites for N2O. IR peaks can be related to particular thermal features by combining TPD spectra with temperature-dependent measurement. By comparing from roughness supports, a band 2236 cm−1 assigned adsorbed MgO terraces, while...
In this article, nanoscale silver paste was used to double-sided attach Insulated Gate Bipiloar Transistor (IGBT) chips. order obtain high bonding strength in sintered assembly, sintering process of studied by orthogonal experiment. The shear joint analyzed with different factors, e.g., temperature, process. Die-shearing tests revealed that larger than 20 MPa generated when firstly pre-dried at 70°C for 10 mins, secondly heated immediately 225°C the help 3.9-5.1 and eventually 300°C mins....
