ELECTROPHORESIS, EarlyView.ABSTRACT The first patent to describe dielectrophoresis (DEP) as a means and process to separate particles from a mixture was granted by the US Patent Office to Henry Stafford Hatfield in 1924. The novel methods of sample preparation and designs of electrode geometry covered by the patent's disclosures and claims describe the basis for most present‐day

Holomorphic versus algebraic equivalence for deformations of real-algebraic CR manifolds [PDF]
Comm. Anal. Geom. 2010, Vol. 18 (5), 891-926, 2011 We consider (small) algebraic deformations of germs of real-algebraic CR submanifolds in complex space and study the biholomorphic equivalence problem for such deformations. We show that two algebraic deformations of minimal holomorphically nondegenerate real-algebraic CR submanifolds are holomorphically equivalent if and only if they are algebraically

eCherry: A Modelica Library for Modular Dynamic Modelling of Electrochemical Reactors
Electrochemical Science Advances, EarlyView.ABSTRACT Electrochemical reactors offer promising pathways for defossilizing the chemical industry. To understand the operation as well as to evaluate and optimise their performance and efficiency, modelling presents a crucial tool. Currently, no comprehensive open‐source library for dynamic modelling of electrochemical reactors exists, and instead ...

Earthquake Engineering &Structural Dynamics, EarlyView.ABSTRACT This article presents the Multi‐Axial Subassemblage Testing facility of ETH Zurich, Switzerland (ETHZ‐MAST) for quasi‐static testing and hybrid simulation (HS) of large‐scale structural components and assemblies. The ETHZ‐MAST features a 6‐degrees‐of‐freedom (DOFs, 3 translations and 3 rotations) loading system based on a steel crosshead and ...

Energy Science &Engineering, EarlyView.ABSTRACT This paper proposes an ejector‐expansion refrigeration cycle (EERC) with two evaporating temperatures to recover partial expansion work and greatly reduces the throttling loss of the other expansion valve connected to the evaporator compared with the conventional bievaporator refrigeration cycle (CBEC).

The Chemical Record, Volume 22, Issue 12, December 2022., 2022 Roald Hoffmann was the perfect theoretical chemist to collaborate with R. B. Woodward on the Principle of Conservation of Orbital Symmetry. This essay presents Hoffmann's capabilities as of May 5, 1964. Abstract Abstract: Why was it that Roald Hoffmann was the perfect collaborator for R. B.

Algebraically Constructible Functions and Signs of Polynomials [PDF]
arXiv, 1996 We show that on real algebraic sets algebraically constructible functions coincide with the finite sums of signs of polynomials. Then we give some applications.

Energy Science &Engineering, EarlyView.ABSTRACT This study investigates double‐diffusive transport and entropy generation in a wavy cylindrical enclosure containing Cu─H2O Casson nanofluid under magnetic field and thermal radiation effects. The governing equations were solved numerically using the finite element method with Galerkin formulation.
