This study adopts an osmotic ethnography in order to decolonise the museum as an intellectual institution that was born in the West and informed by a logic of command (arkheion). As in the biological process of osmosis, characterised by an equilibrium between the inner and the outer that shapes its own distinctiveness through its symbiosis, the museum constitutes itself as a space intertwined with external reality. This is particularly true in the case of South Asian museum artefacts: because of the concept of darśan (the sensuous relationship between the worshipper and the deity's material embodiment) curators have faced the challenge of coming to terms with visitors’ responses, from colonial to post-colonial times. A direct consequence of this challenge is represented by the reconstructions of religious spaces—shrines, altars, temples—that should evoke the so-called “original context” and be in consonance with local forms of material engagement.

By adopting eco-phenomenology as its methodological framework, this article examines colonial sources, in particular the works of Thomas Hendley (1847–1917) and Fanny Parks (1794–1875), and compares them to the ethnographic fieldwork undertaken by the author at the Oriental Museum of the University of Durham in November 2014, as part of doctoral research.

Conventional pNIPAAm microgel synthesis utilizes surfactants to suspend pre-gel droplets in the immiscible continuous phase due to the slow polymerization required for synthesizing pNIPAAm in aqueous solvent. To improve the fabrication process and to eliminate the effects of surfactant on microgel quality, a surfactant-free and water-free method was developed. Rapid polymerization of high-quality microgels was achieved in a single-channel microfluidic device to help maintain the integrity of gel particles without the addition of surfactants. The droplet generation mechanism and the effect of flow rate of the two in-going immiscible fluid on the geometry of the produced microgels were studied. The produced microgels have low polydispersity with a dispersity index of 6.4%. The pNIPAAm hydrogels fabricated in the DMSO solvent has smaller pore size and more uniform microstructure compared to that synthesized in water. The fabricated pNIPAAm microgels show a sharp volume phase transition at ∼32 °C and high deswelling/swelling rate.

Cartilage is a load bearing tissue that has multiple biological functions. Themajor proteoglycan in cartilage is the bottlebrush shaped aggrecan whosecomplexes with hyaluronic acid provide the compressive resistance of cartilage.The negatively charged aggrecan-hyaluronic acid complexes generate an osmoticswelling pressure within the tissue, which is balanced by the collagen network.To better understand the function of cartilage at the tissue level, we studyaggrecan assemblies using an array of microscopic and macroscopic techniques.The organization of aggrecan assemblies at the supramolecular level is probed bylight scattering, small-angle neutron scattering and small-angle X-rayscattering. Osmotic and rheological measurements are used to investigate themacroscopic physical properties.

Within the framework of variational modelling we derive a one-phase moving boundary problem describing the motion of a semipermeable membrane enclosing a viscous liquid, driven by osmotic pressure and surface tension of the membrane. For this problem we prove the existence of classical solutions for a short-time.

Salinity gradient is an enormous source of clean energy. A process for potential generation from an ionic concentration gradient produced in single and multicell assembly is presented. The ionic gradient is created using a fuel cell type cell with a micro-porous ion exchange membrane, both anionic (AEM) and cationic (CEM). Various salinity gradients, Salt : Fresh, from 100 : 0 to 16000 : 0 was established using NaCl solution, in the electrode chambers. A potential of 20 mV/cm to 25 mV/cm can be realized at ambient temperatures and pressures for a bipolar AEM/CEM cell. The performance was optimized for various static and dynamic flow rates of the saline and fresh water. The cell performance can further be optimized for Membrane Electrode System (MES) morphology. A multicell unit was assembled and the results presented for various conditions like concentration gradients, flow rates and pressure. The thermodynamic and electrical efficiency needs to be evaluated for various gradients and flow rates. The relation with number of valance electrons/ ion and the potential generated changes for various dynamic condition of salinity. The higher the salinity gradient the larger is the potential generated. This is limited by the membrane characteristics. There exists a monotonic relation between the number of valence electron/ion/unit time and the potential generated up to about 16000 concentration. The membrane characteristics have been studied for optimal ion crossover for various gradients and flow. The graph between ln (gradient) versus Voltage provides insights into this process. This presents a very cost effective and clean process of energy conversion.

Laboratory water uptake tests are performed at the Belgian Nuclear Research Centre SCK•CEN to obtain insight into the hydromechanical behavior of Eurobitum bituminized radioactive waste under geological disposal conditions. Small nonradioactive and radioactive Eurobitum samples are hydrated in restricted swelling conditions (i.e., nearly constant volume conditions and constant stress conditions). Microfocus X-ray computer tomography (μCT) proves to be a very suitable technique to follow up the ingress of water in the samples. μCT analyses demonstrate that, under the studied hydration conditions, the water uptake by Eurobitum samples is a diffusion controlled process. A characterization of the partially leached samples with environmental scanning electron microscopy (ESEM) shows that the hydration of salt crystals and the subsequent dilution of the salt solution result in an increase in pore size that is limited to a few tens of μm in restricted swelling conditions. The μCT and ESEM analyses allow improvement in the understanding of water uptake by Eurobitum in restricted swelling conditions. In this article we discuss the μCT and ESEM analyses of nonradioactive Eurobitum samples that were hydrated for 2 to 4 years at a constant stress of 1, 22, 33, and 44 bar or in nearly constant volume conditions.
