ENVIE Co-ordination action on indoor air quality and health effects; WP3 Final report – Characterisation of spaces and source

open access: yes, 2012
Human exposure to environmental pollutants occurs via various pathways. For many pollutants, especially the volatile ones, air exposure is the dominant pathway.

Deciphering the role of anions and secondary coordination sphere in tuning anisotropy in Dy(III) air-stable D5h SIMs

open access: yes, 2021
Precise control of the crystal field and symmetry around the paramagnetic spin centre has recently facilitated the engineering of high-temperature single-ion magnets (SIMs), the smallest possible units for future spin-based devices.

Experimental Evaluation of 100Cr6 Steel Microindented Surfaces Under Lubricated Nonconformal Point Contacts

open access: yesAdvanced Engineering Materials, EarlyView.
The tribological behavior of 100Cr6 steel spheres textured via Vickers microindentation is evaluated under lubricated sliding by varying both dimple size and density. Fine and dense textures significantly reduce friction across all lubrication regimes, while large dimples increase it.

Evaluating Fault Detection and Diagnostics Protocols Applied to Air-Cooled Vapor Compression Air-Conditioners

open access: yes, 2012
Fault detection and diagnostics (FDD) tools are being increasingly applied in air-conditioning systems. There are many different protocols used in these FDD tools, so an important question to ask is: how well do the protocols work?

Gas-turbine engine secondary air system analysis

open access: yesIzvestiya MGTU MAMI, 2015
Secondary air system model based on graph theory and one dimentional hydraulic models is discussed. Channel inclination to major axis of integration is taking into account. New hydraulic channel model for smooth transition between “horizontal” and “vertical” flow passages is proposed.

On the Lightweight Potential of Laser Additive Manufactured NiTi Triply Periodic Minimal Sheet Lattices

open access: yesAdvanced Engineering Materials, EarlyView.
This study explores the lightweight potential of laser additive‐manufactured NiTi triply periodic minimal surface sheet lattices. It systematically investigates the effects of relative density and unit cell size on surface quality, deformation recovery, compression behavior, and energy absorption.

Additive Gaussian Process Regression for Predictive Design of High‐Performance, Printable Silicones

open access: yesAdvanced Engineering Materials, EarlyView.
A chemistry‐aware design framework for tuning printable polydimethylsiloxane (PDMS) for vat photopolymerization (VPP) is developed using additive Gaussian process (GP) modeling. Polymer network mechanics informs variable groupings, feasible formulation constraints, and interaction variables.

Pericardiocentesis Complicated by Pneumopericardium

open access: yesJACC: Case Reports, 2019
This report presents the case of pneumopericardium with trapped air in the pericardial sac occurring after a pericardiocentesis, probably caused by air leakage secondary to a defect in the drainage system and/or accidental removal of the pericardial tube.
