Mechanophoric 3‐Arm Star Functional Block Copolymer Based on Rhodamine Derivative
Macromolecular Materials and Engineering, EarlyView.Mechanoresponsive rhodamine containing linear and star block and random copolymers were synthesized and characterized. All materials transitioned into a “switch‐on” state in the film form, but only the star block copolymer architecture exhibited a complete and precise peak shift upon stretching, providing new insights into the mechanochemical ...

A new finite element formulation of three-dimensional beam theory based on interpolation of curvature [PDF]
, 2003 A new finite element formulation of the `kinematically exact finite-strain beam theory' is presented. The finite element formulation employs the generalized virtual work in which the main role is played by the pseudo-curvature vector. The solution of the

Macromolecular Materials and Engineering, EarlyView.Two novel bio‐based epoxy monomers, diglycidyl‐4‐allylphenol (DG‐4A) and triglycidyl‐diallylphenol (TG‐DA), derived from estragole (92% and 72% bio‐content), were synthesized and cured with isophorone diamin (IPDA) and 4,4´‐diaminodiphenyl sulfone (DDS). The resins show high Tgs, with DG‐4A reaching and TG‐DA exceeding DGEBA‐based systems. These resins

Harnessing nuclear spin polarization fluctuations in a semiconductor nanowire
, 2013 Soon after the first measurements of nuclear magnetic resonance (NMR) in a condensed matter system, Bloch predicted the presence of statistical fluctuations proportional to $1/\sqrt{N}$ in the polarization of an ensemble of $N$ spins.

Sustainable Carbon Fiber Composites Based on Recyclable Bio‐Based Vanillin Thermoset Polymers
Polymer Composites, EarlyView.Development of composite materials made from a bio‐based and mechanically recycled vitrimeric polymer matrix. ABSTRACT Although bisphenol A (BPA) is the most used organic compound in the production of thermosets for composite materials, there has been an urgent scientific concern to eliminate it in the last years due to the environmental issues raised ...

Materials selection and design of microelectrothermal bimaterial actuators
, 2007 A common form of MEMS actuator is a thermally actuated bimaterial, which is easy to fabricate by surface micromachining and permits out of plane actuation, which is otherwise difficult to achieve.

The strain-based beam finite elements in multibody dynamics [PDF]
, 2007 We present a strain-based finite-element formulation for the dynamic analysis of flexible elastic planar multibody systems, composed of planar beams. We consider finite displacements, rotations and strains.

Surface and Interface Analysis, EarlyView.ABSTRACT In the present study, we have analyzed the growth profile of ruthenium (Ru) thin films, deposited using pulsed direct current (DC) magnetron sputtering technique, by varying the sputtering voltages in the range of 150–420 V. The grazing incidence X‐ray reflectivity (GIXRR), time‐of‐flight secondary ion mass spectrometry (ToF‐SIMS), and atomic ...

Flattening Energy Puddles for Enhanced Charge Transport in Wrinkled WSe2
Small, EarlyView.Strain‐inducing wrinkles in 1L‐WSe2 create carrier‐trapping energy puddles. Trioctylphosphine selenide (TOPSe) selectively passivates Se vacancies at these wrinkle sites, while steric hindrance suppresses basal‐plane reaction. Comprehensive suite of space‐resolved spectroscopic techniques reveals reduced nonradiative recombination, longer exciton ...
