Equilibrium gas-liquid-solid contact angle from density-functional theory

open access: yes, 2010
We investigate the equilibrium of a fluid in contact with a solid boundary through a density-functional theory. Depending on the conditions, the fluid can be in one phase, gas or liquid, or two phases, while the wall induces an external field acting on ...

Electrowetting-on-Dielectric Actuation of a Vertical Translation and Angular Manipulation Stage [PDF]

open access: yes, 2016
Adhesion and friction during physical contact of solid components in microelectromechanical systems (MEMS) often lead to device failure. Translational stages that are fabricated with traditional silicon MEMS typically face these tribological concerns ...

Upflow Solid Contact Clarifier

open access: yes, 2018
Unit ini menggabungkan unit proses dan operasi koagulasi, flokulasi, separasi zat padat dan sludge removal. Ada juga yang menyebutnya dengan filter. Tidak salah memang, tetapi kurang tepat karena unit ini terdiri atas beberapa unit operasi dan proses. Unit ini tidak membutuhkan flokulator dan sedimentasi secara terpisah. Di Amerika Latin disebut upflow

Measuring Surface Tensions of Soft Solids with Huge Contact-Angle Hysteresis

open access: yesPhysical Review X, 2021
The equilibrium contact angle of a droplet resting on a solid substrate can reveal essential properties of the solid’s surface. However, when the motion of a droplet on a surface shows significant hysteresis, it is generally accepted that the solid’s ...

Progress in Effect of Nano-modified Coatings and Welding Process Parameters on Wear of Contact Tube for Non-copper Coated Solid Wires

open access: yesCailiao gongcheng, 2017
Environment-friendly non-copper coated solid wire is the main developing trend for gas shielded solid wires, whereas wear of contact tube limits their wide application.

Stiffness of Contacts Between Rough Surfaces

open access: yes, 2010
The effect of self-affine roughness on solid contact is examined with molecular dynamics and continuum calculations. The contact area and normal and lateral stiffnesses rise linearly with the applied load, and the load rises exponentially with decreasing

Integration of a sensor system into microfluidic chips [PDF]

open access: yes, 2010
There have been considerable developments in the field of potentiometric sensors in recent years mainly with respect to lowering detection limits and making sensors smaller, solid-state, robust and less expensive.[1, 2] In potentiometric measurements two

Gemcitabine, Docetaxel, Melphalan, Carboplatin as Part of Sequential Cycles of High‐Dose Chemotherapy With Autologous Hematopoietic Stem‐Cell Rescue for Multiply Relapsed/Refractory Pediatric Germ Cell Tumors

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Although most malignant germ cell tumors (GCTs) are highly curable with cisplatin‐based therapy, options for patients with multiply relapsed/refractory disease remain limited. For this population, we report the first pediatric use of gemcitabine, docetaxel, melphalan, and carboplatin (GemDMC) as part of sequential cycles of high‐dose ...

A Review: Contact Electrification on Special Interfaces

open access: yesFrontiers in Materials, 2022
The contact electrification of materials plays an important role in developing and applying triboelectric nanogenerators (TENGs). By exploring the contact electrification phenomena at different interfaces, we can improve the understanding of the ...

In situ molecular organization and heterogeneity of the Legionella Dot/Icm T4SS

open access: yesFEBS Letters, EarlyView.
We present a nearly complete in situ model of the Legionella Dot/Icm type IV secretion system, revealing its central secretion channel and identifying new components. Using cryo‐electron tomography with AI‐based modeling, our work highlights the structure, variability, and mechanism of this complex nanomachine, advancing understanding of bacterial ...
