Surface nanobubbles are nanoscopic gaseous domains on immersed substrates which can survive for days. They were first speculated to exist about 20 years ago, based stepwise features in force curves between two hydrophobic surfaces, eventually leading the atomic microscopy (AFM) image 2000. While early it was suspected that they may be an artifact caused by AFM, meanwhile their existence has been confirmed with various other methods, including through direct optical observation. Their seems...
A combination of AFM, SEM and permeation experiments suggests that the amplitude corrugation chemically converted graphene (CCG) sheets in water can be readily controlled by hydrothermal treatment, leading to a new class permeation-tuneable nanofiltration membranes.
Surface nanobubbles are experimentally known to survive for days at hydrophobic surfaces immersed in gas-oversaturated water. This is different from bulk nanobubbles, which pressed out by the Laplace pressure against any gas oversaturation and dissolve submilliseconds, as derived Epstein Plesset [J. Chem. Phys. 18, 1505 (1950)]. Pinning of contact line has been speculated be reason stability surface nanobubbles. Building on an exact result Popov [Phys. Rev. E 71, 036313 (2005)] coffee stain...
Ein einfacher Weg zu Siliciumoxidfilmen mit senkrechten Mesokanälen: Das Substrat wird in eine Stöber-Lösung getaucht, der die Siliciumoxidvorstufen hydrolysiert, Ammoniak als Katalysator vernetzt und mithilfe eines Tensids auf dem hexagonalen Mesostrukturen zusammengefügt werden, senkrecht zur Substratoberfläche angeordnet sind. Detailed facts of importance to specialist readers are published as ”Supporting Information”. Such documents peer-reviewed, but not copy-edited or typeset. They...
Strain sensors with high elastic limit and sensitivity are required to meet the rising demand for wearable electronics. Here, we present fabrication of highly sensitive strain based on nanocomposites consisting graphene aerogel (GA) polydimethylsiloxane (PDMS), primary focus being tune by tailoring cellular microstructure through controlling manufacturing processes. The resultant nanocomposite exhibit a gauge factor up approximately 61.3. Of significant importance is that can be readily...
Interfacial nanobubbles (INBs) on a solid surface in contact with water have drawn widespread research interest. Although several theoretical models been proposed to explain their apparent long lifetimes, the underlying mechanism still remains dispute. In this work, morphological evolution of INBs was examined air-equilibrated and partially degassed use atomic force microscopy (AFM). Our results show that (1) shrank while they grew slightly water, (2) three-phase boundary pinned during INBs....
Mesoporous solids have been widely used in various biomedical areas such as drug delivery and tumor therapy. Although deformability has recognized a prime important characteristic influencing cellular uptake, the synthesis of deformable mesoporous is still great challenge. Herein, thioether-, benzene-, ethane-bridged hollow periodic organosilica (HPMO) nanocapsules successfully synthesized for first time by preferential etching approach. The prepared HPMO possess uniform diameters (240-310...

Abstract The poor mechanical strength and low water retention of biomass adhesives present significant challenges when substituting petrochemical in practical applications. Inspired by the colloidal gel structure Tofu, development a high‐performance protein‐based adhesive derived from soybean meal (SM) oxidized glucose oxidase (GOx) calcium sulfate oligomer (CSO) is reported. catalytic oxidation sugars SM GOx produces active carboxyl groups, increasing sites for bridge (sugar‐protein)...
The growing demand for high-strength, durable materials capable of enduring extreme environments presents a significant challenge, particularly in balancing performance with sustainability. Conventional such as alloys and ceramics are nonrenewable, expensive, require energy-intensive production processes. Here, super-hard wood-based composites (WBC) inspired by the meso-scale homogeneous lignification process intrinsic to tree growth designed developed. This hybrid structure is achieved...
Nanodroplets on a solid surface (i.e. nanodroplets) have practical implications for high-throughput chemical and biological analysis, lubrications, lab-on-chip devices, near-field imaging techniques. Oil nanodroplets can be produced solid-liquid interface in simple step of solvent exchange which good oil is displaced by poor solvent. In this work, we experimentally theoretically investigate the formation process under well-controlled flow conditions. We find that contact angle independent...
To understand the unexpected and puzzling long-term stability of nanoscale gas bubbles, it is crucial to probe their nature intrinsic properties. We report herein synchrotron-based scanning transmission X-ray microscopy (STXM) evidence highly condensed oxygen molecules trapped as surface nanobubbles. Remarkably, analysis absorption spectra a single nanobubble revealed that density inside was 1–2 orders magnitude higher than in atmospheric pressure, these bubbles were found saturated liquid...
