Analysis of Carbohydrates and Glycoconjugates by Matrix‐Assisted Laser Desorption/Ionization Mass Spectrometry: An Update for 2023–2024

open access: yesMass Spectrometry Reviews, EarlyView.
ABSTRACT The use of MALDI mass spectrometry for the analysis of carbohydrates and glycoconjugates is a well‐established technique and this comprehensive review is the twelfth update of the original article published in 1999 and brings coverage of the literature to the end of 2024.

A simple design for circularly polarized ring-slot antennas

open access: yes, 2012
[[abstract]]A simple method for generating circular polarization (CP) radiation from an annular-ring slot antenna is described in this paper.The slot antenna is excited by an L-shaped coupling strip loaded with a resistor.

Analysis of Mechanical‐Electrical‐Hydraulic Coupled Vibration Response Characteristics of Thermal Control Circulating Pumps Supported by Water‐Lubricated Bearings

open access: yesInternational Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT The operational reliability of thermal control circulation pumps is significantly restricted by the multi‐physics coupled environment. To reveal the vibration transmission mechanisms and dynamic response characteristics under multi‐field coupled excitations, a multi‐DOF coupled dynamic representation of the overall system, incorporating the ...

Monitoring shallow geothermal aquifers with active‐source distributed acoustic sensing: A prognostic feasibility study on the University of Leeds Geothermal Campus

open access: yesNear Surface Geophysics, EarlyView.
Abstract The United Kingdom's shallow aquifers offer significant but underdeveloped geothermal energy resource. Seismic methods can help address this by improving the understanding of aquifer heterogeneity and potentially allowing long‐term monitoring of thermal plumes.

Interfacially Engineered Alginate/Hydroxyapatite Biocomposites With High Strength and Toughness

open access: yesPolymer Composites, EarlyView.
Pre‐crosslinking alginate with Ca2+ prior to hydroxyapatite (HAP) formation reduces residual Ca2+ bridging and promotes stronger carboxylate‐hydroxyapatite interfacial interactions, yielding composites with markedly higher strength, stiffness, and toughness than those prepared by the opposite sequence.

Simulation of the Rotational Molding Process of Polyethylene Using the Smoothed Particle Hydrodynamics Method

open access: yesPolymer Engineering &Science, EarlyView.
Numerical simulation of polyethylene rotational molding using the Smoothed Particle Hydrodynamics (SPH) method. ABSTRACT This work presents the development of a numerical model based on the smoothed particle hydrodynamics (SPH) method to simulate the rotational molding process of powder thermoplastic polymers, used in the manufacture of liners for high‐

Optimizing Atmospheric Pressure Plasma Surface Treatment of Polymer Melts to Achieve Adhesion‐Promoter Free Multilayer Films

open access: yesPolymer Engineering &Science, EarlyView.
Atmospheric‐pressure plasma treatment of the polyethylene melt at the die exit enables direct joining with a polyamide melt without adhesion promoters. After process optimization, the peel strength of the PE/PA laminates increased from 0.03 to 2.92 N/mm.
