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.

Dynamics and uniformity of reorientation in liquid crystal cells with PVK alignment layers

open access: yes, 2003
We present experimental results on dynamics of Freedericksz transition in liquid crystal cells with alignment layers made of poly(N-vinyl carbazole). DC electric field causes the build-up of, unusually strong, surface charge layers on a liquid crystal ...

The synthesis of new main-chain liquid crystalline polymers as materials for non-linear optics [PDF]

open access: yes, 1991
The work described in this thesis is concerned with the synthesis of new main-chain liquid crystalline polymers. A new series of liquid crystalline monomers based on an unsymmetrically disubstituted stilbene containing alcohol and carboxylic acid, groups

Study of polymer-dispersed liquid crystal systems using epoxies/acrylates as hybrid polymer matrix components

open access: yes, 2012
Hybrid polymers, which form a combination of monomers with different reactive groups and curing mechanisms, synergistically combine the properties of the two constituent homopolymers. It will be of interest to use these monomers together, with the aim of

Tailored Hierarchical Porous Copper Architectures via Three Dimensional Printing and Pressure‐less Sintering for Next‐Generation Lithium‐Metal Batteries

open access: yesAdvanced Engineering Materials, EarlyView.
A hierarchical porous copper current collector is fabricated via three‐dimensional printing combined with pressureless sintering to stabilize lithium metal anodes. The interconnected architecture lowers local current density, guides uniform Li deposition within pores, and suppresses dendrite growth.

FTIR-ATR studies on polymer/polymer and polymer/liquid interfaces. [PDF]

open access: yes, 1994
Fourier Transform Infrared Attenuated Total Reflection Spectroscopy (FTIR-ATR) has been employed to study polymer laminates composed of poly (methylmethacrylate) (PMMA) and poly(vinyl alcohol) (PVOH) using different base layer thicknesses and different ...

Confinement-Induced Fractionation and Liquid–Liquid Phase Separation of Polymer Mixtures

open access: yes, 2023
The formation of (bio)molecular condensates via liquid–liquid phase separation in cells has received increasing attention, as these aggregates play important functional and regulatory roles within biological systems.

Effects of Composition and Polymerization Conditions on the Electro-Optic Performance of Liquid Crystal–Polymer Composites Doped with Ferroelectric Nanoparticles

open access: yesNanomaterials
The presence of a polymer network and/or the addition of ferroelectric nanoparticles to a nematic liquid crystal are found to lower transition temperatures and birefringence, which indicates reduced orientational order.

Near‐Field Electrospinning Micro‐Printhead Achieves Precise Control of Nanofiber Deposition

open access: yesAdvanced Engineering Materials, EarlyView.
A micro‐printhead for near‐field electrospinning enables reproducible deposition of polymer nanofibers with diameters below 50 nm. Systematic parameter studies uncover the mechanisms linking operating conditions to fiber morphology, paving the way for precise and low‐cost nanoscale 3D manufacturing.As a high‐resolution, cost‐effective, and rapid ...

Combined Process‐ and Phase‐Field‐Simulation to Predict the Microstructure of Single‐Crystal Ni‐Based Superalloys

open access: yesAdvanced Engineering Materials, EarlyView.
A combined finite element and phase‐field approach predicts the evolution of microstructure during the directional solidification of Ni‐based superalloys. The model reveals how withdrawal rate, temperature gradient, and wall thickness control the dendrite spacing, highlighting the strong effect of surface regions in thin sections where dendrite growth ...
