Self-similarity of contact line depinning from textured surfaces
We observe a higher microscale receding angle for the capillary bridges on the nanograss-covered micropillars as compared with the smooth micropillars. We propose that this is due to a self-similar depinning mechanism, for which the total pinned length of the contact lines at each level of the hierarchical roughness must be taken into account. Considering a droplet sitting on a surface comprising multiple levels of roughness features (Fig. 5a), the apparent macroscopic contact line of the drop comprises the zeroth level of hierarchy and will actually be divided into many smaller contact lines, each sitting on top of a roughness…
Depinning probability of a magnetic domain wall in nanowires by spin-polarized currents
Sample structure and magnetic properties For DW stabilization experiments, multiple perpendicularly magnetized Co/Ni layers are used18 was used deposited on Si substrate. This is a promising material for application to DW motion devices due to it having several advantages in terms of stable operation and retention properties21,22,23due to its nature that the DW can be driven by an adiabatic STT22. By measuring the overall film magnetization curves along both the in-plane and out-of-plane directions, the saturation magnetization was obtained MQthe vertical anisotropy constant and the forced field were obtained to be 0.96 T, 6.1 × 105JM-3and 16.5 metric tons, respectively,…

Suppression of the coffee-ring effect by sugar-assisted depinning of contact line
Boiled water at a temperature of approximately 80 °C was poured into ground coffee powders to make a brewed coffee. When a coffee drop (0.5 μL) was evaporated on a solid substrate (here pre-cleaned ceramic dish plate), a ring-like stain was observed (Fig. 1a,b). During the evaporation, the temperature and relative humidity were fixed, i.e., T = 298 ± 2 K and RH = 40 ± 3%. The particle size was approximately 100 nm in radius using dynamic light scattering (Supplementary Fig. S1). In contrast, when sugar (caster sugar, ~98% sucrose) was used to moderately sweeten the coffee (a 0.5 μL coffee drop with a sugar concentration of 200 mM), no ring-like stains were observed, and…
Oxidized-monolayer tunneling barrier for strong Fermi-level depinning in layered InSe transistors
The InSe samples are mechanically exfoliated from InSe crystals onto a highly doped Si substrate with a 300 nm SiO2 dielectric layer under ambient conditions. After exfoliation, we grown the surface OL on InSe flakes by employing UV–ozone treatment at 80 °C for 10 s. The atomic structure and chemical properties of the surface OL are examined by cross-sectional transmission electron microscopy (TEM) and energy-dispersive X-ray spectroscopy (EDX) mapping, as shown in Fig. 1a. Remarkably, the OL is uniformly grown, and the underlying InSe layers remain of a high-quality crystallinity, highlighting an atomically sharp and clean interface. The surface OL is amorphous with…
Phyllis A. Manville Depin Obituary Sep 13, 2020
Phyllis A. died. Manville Deppen, 85, of Tiverton, Rhode Island, daughter of the late Philip R. Manville and Katherine (O’Neill) Manville, passed away peacefully on Sunday, September 13, 2020 at John Clark Nursing Center, Middletown Rhode Island. Phyllis graduated from Mount St. Mary’s Academy, Fall River, Massachusetts, where she made many lifelong friends. Phyllis then moved into the insurance field starting with Travelers Insurance Co. She continued in the industry and eventually became the owner and operator of the former B. McDermott Insurance Agency in Fall River, MA for over 35 years before her retirement.

Critical behavior of nonequilibrium depinning transitions for vortices driven by current and vortex density
In Fig. 1a,c, we show the current-voltage (I–V) characteristics at 4.1 K in 1.27 and 3.8 T, respectively, on a linear-linear scale. In the insets, the I–V data in the main panels, including additional data, are plotted on a log-log scale. We define \(I_{d}\) as a threshold current at which the vortices start to move, using a \(10^{-8}\) V criterion9. The location of \(I_{d}\) = 0.375 mA for each field is marked with a vertical arrow and dashed line in the main panel and inset, respectively. Upward curvature of the I–V characteristics just above \(I_{d}\) in the main panels indicates that…
