ALD‐Assisted VO2 for Memristor Application

open access: yesAdvanced Engineering Materials, EarlyView.
This work demonstrates a strategy for depositing VOx using thermal atomic layer deposition (ALD) followed by thermal annealing to synthesize VO2. The thin film and core/shell wire memristors exhibit excellent switching performance and are highly sensitive to ambient temperature.

Structural Topology Optimization for Abrasive Water-Jet Fabricated Glass

open access: yesChallenging Glass Conference Proceedings
The application of structural topology optimization to glass may enable the design of architectural and lightweight glass structures. There is still a lack of specific topology optimization tools for such a brittle material.

Topology optimization for transient response of structures subjected to dynamic loads [PDF]

open access: yesarXiv, 2017
This paper presents a topology optimization framework for structural problems subjected to transient loading. The mechanical model assumes a linear elastic isotropic material, infinitesimal strains, and a dynamic response. The optimization problem is solved using the gradient-based optimizer Method of Moving Asymptotes (MMA) with time-dependent ...

Phase-field approaches to structural topology optimization [PDF]

open access: yes, 2010
The mean compliance minimization in structural topology optimization is solved with the help of a phase field approach. Two steepest descent approaches based on L2- and H-1 gradient flow dynamics are discussed. The resulting flows are given by Allen-Cahn

A "poor man's" approach to topology optimization of natural convection problems

open access: yes, 2019
Topology optimization of natural convection problems is computationally expensive, due to the large number of degrees of freedom (DOFs) in the model and its two-way coupled nature.

Multiple‐Repeated Plasma Surface Treatments for Significantly Improving Bonding Performance of Metal‐Carbon‐Fiber‐Reinforced Thermoplastic Polymer Dissimilar Adhesive Joints

open access: yesAdvanced Engineering Materials, EarlyView.
Multiple plasma surface treatments improved the Mode I fracture energy of metal‐carbon‐fiber‐reinforced thermoplastic polymer (CFRTP) joints by ≈240% compared to single treatments and nearly 2000% over untreated joints. This significant enhancement, achieved without modifying CFRTP surface roughness, is attributed to improved chemical bonding at the ...

An Examination of Aerosol Jet‐Printed Surface Roughness and its Impact on the Performance of High‐Frequency Electronics

open access: yesAdvanced Engineering Materials, EarlyView.
This study explores aerosol jet‐printed (AJP) surface roughness, its effects on the performance of microwave electronics, and its process contributors. First, an electromagnetic model is vetted for AJP's unique roughness signature. Simulations are built which show process‐induced roughness is as significant as conductor resistivity in driving microwave

Low‐Velocity Penetration Impact Behavior of Triply Periodic Minimal Surface Strut‐Based Lattices

open access: yesAdvanced Engineering Materials, EarlyView.
Triply periodic minimal surface (TPMS)‐based lattices are gaining attention for their multifunctional properties in applications as aeronautics and automotive, which involve low‐velocity impact loading. This work evaluates the low‐velocity penetration impact behavior of five distinct TPMS architectures.

Reconstruction of the core convex topology and its applications in vector optimization and convex analysis [PDF]

open access: yesarXiv, 2017
In this paper, the core convex topology on a real vector space $X$, which is constructed just by $X$ operators, is investigated. This topology, denoted by $\tau_c$, is the strongest topology which makes $X$ into a locally convex space. It is shown that some algebraic notions $(closure ~ and ~ interior)$ existing in the literature come from this ...
