The measurement of adsorption of cytochromes c onto the external surfaces of a thin film mesoporous silicates (MPS) supported by silicon wafers was discussed. Adsorption in a multilayered system consisting silicon, SiO 2, MPS, and adsorbed proteins was analyzed using ellipsometry. Synthesis of MPS thin films on 0.5 mm thick silicon wafers was done using a dip-coating alcohol vaporization method. I

Mesoporous silica vesicles (MSV) with a hierarchical structure were developed using triblock copolymer Pluronic P103 and anionic surfactant sodium dodecyl sulfate (SDS) as a co-surfactant in the present of an inorganic salt, sodium fluoride (NaF). To some extent, variation in the particle size and vesicle cavity diameter can be achieved by adjusting the anionic-nonionic surfactant molar ratio. An

A strategy for the formation of thin reconstituted cellulose films (pure or modified)) with embedded receptors or embedded ion-selective components is reported. Cellulose nanofibril ribbons from sisal of typically 3-5 nm diameter and 250 nm length are reconstituted into thin films of typically 1.5-2.0 μm thickness (or into thicker free-standing films). Cellulose and cellulose nanocomposite films a

Surfactant-templated polymer films prepared from polyethylenimine (PEI), cetyltrimethylammonium bromide (CTAB), and octaethylene glycol monohexadecyl ether (C16E8) were examined and the effect of increasing the percentage of nonionic surfactant in the micelles measured using both surface and bulk-sensitive techniques. It was found that there is a strong interaction between CTAB and C16E8, although

Keggin tungstophosphoric acid supported onto mesoporous and meso-microporous materials was studied by ammonia microcalorimetry. Experiments were performed at high and low temperatures to separate the contributions of chemisorpdon and physisorption, low-temperature data being potentially important for the ambient temperature purification processes. Analysis of thermokinetic data obtained from heat

There has been little, or no, direct testing of theories of gas sorption within particular pores situated amidst a highly inter-connected pore network. The concept of thermodynamically independent pores within networks has also been challenged. In this work, a novel integrated nitrogen sorption and mercury porosimetry technique has been used to deconvolve the condensation and evaporation processes

Solid cetyltrimethylammonium bromide (CTAB) and polyethylenimine (PEI) films self-assemble at the air/water interface. Small angle X-ray scattering (SAXS) measurements show that dried films maintain the same ordered mesostrueture as the films at the air/water interface, and here the effects of PEI concentration and cross-linker (CL) on film mesostrueture were investigated. Free-standing silica fil

Mesostructured thin films are known to form at the interface between either air or a solid surface and a dilute acidic solution containing the silica precursor, and surfactant template. These films are transparent, and, when grown at the air/solution interface, self-supporting. We have been studying the formation processes of these films to try to understand and thus control the formation of both

Using a model disordered mesoporous solid with a spatial arrangement of pore sizes analogous to a macroscopic 'ink-bottle', it has been shown that the hysteresis observed in NMR cryoporometry can be deconvoluted into separate single pore and pore-blocking contributions. The suggestion of pore-blocking effects has been confirmed using PFG NMR. Hence, percolation theory has been used, for the first

Brewster angle micrographs have been obtained of the development of a silica film grown at an air-water interface with use of the surfactant template cetylpyridinium chloride. The micrograph images showed that the growing silica film exhibited complex, fractal-like patterns. These images have been analyzed to determine the values of the fractal dimension and lacunarity, and the forms of the autoco

Studies on late effects in patients with mantle cell lymphoma (MCL) are becoming increasingly important as survival is improving, and novel targeted drugs are being introduced. However, knowledge about late effects is limited. The aim of this population-based study was to describe the magnitude and panorama of late effects among patients treated with or without high-dose chemotherapy with autologo

Mouse hematopoietic stem cells (HSCs) have been extensively defined both molecularly and functionally at steady state, while regenerative stress induces immunophenotypical changes that limit high purity isolation and analysis. It is therefore important to identify markers that specifically label activated HSCs to gain further knowledge about their molecular and functional properties. Here, we asse

Exercise training prevents age-related decline in muscle function. Targeting epigenetic aging is a promising actionable mechanism and late-life exercise mitigates epigenetic aging in rodent muscle. Whether exercise training can decelerate, or reverse epigenetic aging in humans is unknown. Here, we performed a powerful meta-analysis of the methylome and transcriptome of an unprecedented number of h

Advanced psychiatric treatments remain uncertain in preventing suicide among adolescents. Across the 21 Swedish regions, using nationwide registers between 2016–2020, we found negative correlation between adolescent excess suicide mortality (AESM) and regional frequencies of clozapine, ECT, and lithium (CEL) usage among adolescents (β = −0.613, p = 0.0003, 95% CI: −0.338, −0.889) and males (β = −0

It has been known for decades that risk factors for diabetes and cardiovascular disease (CVD) tend to cluster. Metabolic syndrome refers to this risk factor clustering for some of the more well-established and dangerous risk factors. This chapter provides a historical overview on the concept of the metabolic syndrome; describes the clinical criteria used in the definition of the metabolic syndrome

In polaritons, the properties of matter are modified by mixing the molecular transitions with light modes inside a cavity. Resultant hybrid light-matter states exhibit energy level shifts, are delocalized over many molecular units, and have a different excited-state potential energy landscape, which leads to modified exciton dynamics. Previously, non-Hermitian Hamiltonians have been derived to des

We are working towards a mixed reality-based human-robot collaboration interface using gaze and gesture as methods of communicating intent in a search and rescue scenario to optimize the operation. The lack of mature algorithms and control schemes for autonomous systems makes it still difficult for them to operate safely in high-risk environments. We are approaching the problem through symbiosis w

Hyperkalemia is a relatively common electrolyte abnormality that in serious cases can lead to life-threatening arrhythmias. There are a number of factors that can contribute to hyperkalemia, and in most cases some level of kidney failure is present. The management of hyperkalemia depends on the underlying cause and the level of potassium. This paper briefly examines the pathophysiological mechanis

The aqueous humor actively interacts with the trabecular meshwork (TM), juxtacanalicular tissue (JCT), and Schlemm's canal (SC) through a dynamic fluid-structure interaction (FSI) coupling. Despite the fact that intraocular pressure (IOP) undergoes significant fluctuations, our understanding of the hyperviscoelastic biomechanical properties of the aqueous outflow tissues is limited. In this study,
