“…[69] In some cases, the optical resolution in the vicinity of the contact line can be restricted due to the obstructed line of sight (e.g., curvy surfaces), light scattering and diffraction, thus obstructing accurate positioning of the tangent line. [70,71] Instead of identifying the actual contact point, the droplet profile can also be fitted to theoretical models to estimate the CA value. Among the techniques that have been used include the Young-Laplace fitting, polynomial fitting, elliptical fitting and circular fitting.…”

www.advmatinterfaces.de the sessile CA remains the favored method for quantifying wettability, mostly due to its conceptual and measurement simplicity. [9,31] However, the classification on the basis of the cut-off CA of 90° has attracted criticism. [32,33] The simplistic evaluation criteria of relative wettability are becoming inadequate in satisfying the needs of superwettability studies to classify different wetting phenomena. [34] Several works have questioned the accuracy of the sessile-droplet measurement as the CA value approaches the limits of 0° or 180°. [35,36] Yet, evaluation of surfaces in the superhydrophobic (CA > 150°) and superhydrophilic (CA < 10°) regimes is central in the development of enhanced wettabilities. Moreover, the interpretation of the CA results is often complicated by several factors, including surface smoothness, heterogeneity and cleanliness.

Steam condensation is omnipresent, and inevitable in many industrial processes. A classic example is seen within condensers that are used to liquify various gasses. In consequence, water‐vapor is eventually deposited upon the exterior of heat pipes that passively cool the gas to form a thin film of liquid. This macroscopic film is responsible for the degradation of heat transfer efficiencies. Liquid repellent surfaces can microscopically manipulate the hydrodynamics of formulating condensate to transition toward dropwise/jumping‐droplet condensation. This effect will save operating and maintenance costs of steam condensers within power‐plants, subsequently reducing emissions, operating power, and fuel consumption. However, the challenges associated with the stabilization of dropwise/jumping‐droplet condensation, especially at large subcooling temperatures and high supersaturation ratios, have prohibited the use of liquid repellent surfaces. This review aims to discuss recent improvements and understanding of dropwise/jumping‐droplet condensation surfaces on superhydrophobic surfaces. Numerous examples shall be included, showing experimental and numerical studies of various innovative properties of superhydrophobic structures. In addition, various fabrication techniques of superhydrophobic surfaces that are applicable within industrial systems are discussed. These topics are consolidated to provide guidelines for future research into dropwise/jumping‐droplet condensation on liquid repellent surfaces.

“…Since H. K. Onnes observed the superconductivity of Hg in 1911, researchers have been trying many ways to find new superconductors or improve their superconducting properties. For example, cuprate high-temperature superconductor HgBa 2 Ca 2 Cu 3 O 8+δ with critical temperature (T c ) of 133 K was discovered [1], whose T c was improved to 164 K in diamond anvil cells [2]; the T c of Bi 2 Sr 2 CaCu 2 O 8+δ was altered from 84 K to 94 K via a shockwave treatment [3]. Recently, many hydrides with T c s exceeding 200 K were discovered under high pressure [4][5][6], e.g., H 3 S with 203 K at 155 GPa [7][8][9][10] and LaH 10 with 250-160 K at 170 GPa [11][12][13][14].…”

Room temperature superconductivity is a dream that mankind has been chasing for a century. In recent years, the synthesis of H3S, LaH10, and C-S-H compounds under high pressures has gradually made that dream become a reality. But the extreme high pressure required for stabilization of hydrogen-based superconductors limit their applications. So, the next challenge is to achieve room-temperature superconductivity at significantly low pressures, even ambient pressure. In this work, we design a series of high temperature superconductors that can be stable at moderate pressures by incorporating heavy rare earth elements Yb/Lu into sodalite-like clathrate hexahydrides. In particular, the critical temperatures (Tc) of Y3LuH24, YLuH12, and YLu3H24 can reach 283 K at 120 GPa, 275 K at 140 GPa, and 288 K at 110 GPa, respectively. Their critical temperatures are close to or have reached room temperature, and minimum stable pressures are significantly lower than that of reported room temperature superconductors. Our work provides an effective method for the rational design of low-pressure stabilized hydrogen-based superconductors with room-temperature superconductivity simultaneously and will stimulate further experimental exploration.
