PEG Alternatives in Liposomal Nanocarriers: Physicochemical Characteristics and Sustainable Process Strategies

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT The global trend toward sustainable and intensified bioprocesses is driving innovation in the design and scalable synthesis of liposomal nanocarriers, a cornerstone of modern drug delivery. For decades, these nanosystems have relied exclusively on polyethylene glycol (PEG) for their sustained circulation in vivo, but they are currently ...

Spin dynamics of quantum spin-ladders and chains

open access: yes, 2007
This thesis describes the neutron scattering measurements of magnetic excitations in spin-chains and ladders. The first part discusses an experimental investigation of the copper oxide family Srâ â Cuâ â Oâ â composed of edge-sharing chains and ...

A New Paradigm for Understanding the Rheology and Processability of Poly(p‐Phenylene Terephthalamide) Liquid‐Crystalline Solutions

open access: yesJournal of Applied Polymer Science, EarlyView.
Kevlar is traditionally modeled as a rigid‐rod polymer, yet rheological behavior deviates from this assumption. The review introduces a novel “twist‐tie” entanglement theory for aramid polymer chains in the nematic liquid crystal state, providing a molecular explanation for deviations from rigid‐rod models. Understanding twist‐tie entanglement dynamics

Ultra-high resolution inelastic neutron scattering

open access: yes, 1993
Two types of ultra high energy resolution neutron scattering instruments, the backscattering spectrometer and the spin echo spectrometer, are described. Examples of the types of research which can be done with these instruments are given and plans for a ...

Tuning the Magnetic Phase Transitions in TbMn2‐xTixSi2 (x = 0–0.3)

open access: yesAdvanced Physics Research, EarlyView.
ABSTRACT Magnetocaloric materials receive considerable attention as promising candidates for next‐generation energy‐efficient and environmentally benign solid‐state refrigeration technologies. These materials exhibit the magnetocaloric effect (MCE), whereby heat is absorbed or released upon the application or removal of a magnetic field. In this study,

A study of the physical properties of polymer monolayers spread at the air-water interface [PDF]

open access: yes, 1992
An account is given of the methods of anionic polymerisation and characterisation used to prepare polymer samples, and the experimental methods used to examine their interfacial properties, when spread as so-called Langmuir monolayers on water ...

Neutron phase filtering for separating phase- and attenuation signal in aluminium and anodic aluminium oxide

open access: yesScientific Reports
Neutron imaging has gained significant importance as a material characterisation technique and is particularly useful to visualise hydrogenous materials in objects opaque to other radiations.

From brush conformation to 3D Supraparticles: Programmable self‐assembly of polymer‐grafted nanoparticles in emulsion confinement

open access: yesBulletin of the Korean Chemical Society, EarlyView.
This review highlights how the conformational adaptability of polymer‐grafted nanoparticles drives their programmable self‐assembly within 3D emulsion droplets. By coupling brush thermodynamics with soft confinement, these dynamic building blocks form hierarchical supraparticles tailored for advanced plasmonics, compartmentalized catalysis, and stimuli‐
