Ultra‐Fast Non‐Volatile Resistive Switching Devices with Over 512 Distinct and Stable Levels for Memory and Neuromorphic Computing

open access: yesAdvanced Functional Materials, EarlyView.
A materials and device design concept that comprises a self‐assembled ultra‐thin epitaxial ion‐transporting layer, an amorphous oxide overcoat oxygen‐blocking layer, and a partial filament formed during an electroforming step is proposed for low‐current multilevel resistive switching devices.

Intermittent Resistance Exercise: Evolution from the Steady State

open access: yesCentral European Journal of Sport Sciences and Medicine, 2014
Oxygen uptake measurements are without question useful and a staple measurement for the estimation of exercise energy costs. However, steady state models cannot be used to successfully model intermittent resistance exercise energy costs.

Mesenchymal Stem Cells‐Derived Extracellular Vesicles Mimetics as Osteoinductive Mediators for Bone Healing

open access: yesAdvanced Functional Materials, EarlyView.
Mesenchymal stem cell‐derived nanoghosts (MSC‐NGs) mimic naturally secreted extracellular vesicles (MSC‐EVs) in structure and physicochemical properties but can be synthesized at more translatable yields. As osteogenic agents, MSC‐NGs demonstrate superior outcomes compared to MSC‐EVs.

Excess oxygen in La_{2-x}Sr_xCoO_4 [PDF]

open access: yesarXiv, 2017
The amount of non-stoichiometric oxygen in La_{2-x}Sr_xCoO_{4+y} is calculated from Sr doping, x, and the measured stripe incommensurability 2delta for x = 1/4 and x = 1/3 based on a linear or square-root dependence of delta(x, y). The results favor the square-root dependence and indicate that the range of excess oxygen extends to x < 0.4 instead of to

Optimum oxygen content in La0.7Sr0.3MnO3 thin films [PDF]

open access: yesarXiv, 2011
The technological conditions of oxygen content variation in epitaxial La0.7Sr0.3MnO3-{\delta} films and the peculiarities of change of their transport characteristics were investigated. The films were grown onto single crystal SrTiO3 substrates by an enhanced method of dc magnetron sputtering of a ceramic target.

A Gym for Cells—Direct Laser Writing of Magnetic Multilayered Micro Actuators for Mechanical Stimulation of Cells

open access: yesAdvanced Functional Materials, EarlyView.
Surface‐attached multilayer micromagnet systems are fabricated by two‐photon crosslinking. The pillar‐shaped micro actuators consist of a soft and flexible surface‐attached cell‐repellent hydrogel layer at the bottom, acting as a hinge and a cell‐adhesive hydrophobic polymer filled with magnetic nanoparticles.

Integrating water flow, locomotor performance and respiration of Chinese sturgeon during multiple fatigue-recovery cycles.

open access: yesPLoS ONE, 2014
The objective of this study is to provide information on metabolic changes occurring in Chinese sturgeon (an ecologically important endangered fish) subjected to repeated cycles of fatigue and recovery and the effect on swimming capability.

ZnO and ZnO$_{1-x}$ based thin film memristors: The effects of oxygen deficiency and thickness in resistive switching behavior [PDF]

open access: yes, 2017
In this study, direct-current reactive sputtered ZnO and ZnO1-x based thin film (30 nm and 300 nm in thickness) memristor devices were produced and the effects of oxygen vacancies and thickness on the memristive characteristics were investigated. The oxygen deficiency of the ZnO1-x structure was confirmed by SIMS analyses.

Toward Architected Microstructures Using Advanced Laser Beam Shaping in Laser Powder Bed Fusion of Ti‐6Al‐4V

open access: yesAdvanced Functional Materials, EarlyView.
This research applies advanced laser beam shaping (LCoS‐SLM) to fabricate the Ti‐6Al‐4V alloy via laser powder bed fusion. A tailored beam is used to prevent martensite formation and create a dual α+β microstructure by controlling cooling rates.
