Localized Pulsed Electrodeposition Process for Three-Dimensional Printing of Nanotwinned Metallic Nanostructures.

Nanotwinned (nt) metals offer superior mechanical (high ductility and strength) and electrical properties (low electromigration) compared to their nanocrystalline (nc) counterparts. These properties are advantageous in particular for applications in nanoscale devices. However, fabrication of nt-metals has been limited to films (2D) or template-based 1D geometries, using various chemical and physical processes. In this letter, we demonstrate the ambient environment L-PED (localized pulsed electrodeposition) ...

Reaching the end of the line: Operational issues with implementing phone-based unannounced pill counts in resource-limited settings.

Accurate measurement of adherence is necessary to ensure that therapeutic outcomes can be attributed to the recommended treatment. Phone-based unannounced pill counts were shown to be feasible and reliable measures of adherence in developed settings; and have been further used as part of medication adherence interventions. However, it is not clear whether this method can be implemented successfully in resource-limited settings, where cellular network and mobile phone coverage may be low. Our objective is to...

Using phone sensors and an artificial neural network to detect gait changes during drinking episodes in the natural environment.

Phone sensors could be useful in assessing changes in gait that occur with alcohol consumption. This study determined (1) feasibility of collecting gait-related data during drinking occasions in the natural environment, and (2) how gait-related features measured by phone sensors relate to estimated blood alcohol concentration (eBAC).

Feasibility and Validity of Printing 3D Heart Models from Rotational Angiography.

Rotational angiography (RA) has proven to be an excellent method for evaluating congenital disease (CHD) in the cardiac cath lab, permitting acquisition of 3D datasets with superior spatial resolution. This technique has not been routinely implemented for 3D printing in CHD. We describe our case series of models printed from RA and validate our technique. All patients with models printed from RA were selected. RA acquisitions from a Toshiba Infinix-I system were postprocessed and printed with a Stratasys Ed...

Three-dimensional printed skull base simulation for transnasal endoscopic surgical training.

Transnasal endoscopic skull base surgery (SBS) presents a great challenge for inexperienced neurosurgeons due to the complicated anatomic structures, 2-dimensional endoscopic view, limited operative field, and required skills. We designed a personalized multi-material and multi-color three-dimensional (3D)-printed SBS simulation to reproduce the complex anatomy of the skull base. The fidelity and feasibility for anatomical education and surgical training were assessed.

3D cell printing of in vitro stabilized skin model and in vivo pre-vascularized skin patch using tissue-specific extracellular matrix bioink: A step towards advanced skin tissue engineering.

3D cell-printing technique has been under spotlight as an appealing biofabrication platform due to its ability to precisely pattern living cells in pre-defined spatial locations. In skin tissue engineering, a major remaining challenge is to seek for a suitable source of bioink capable of supporting and stimulating printed cells for tissue development.

Experimental Exploration of Metal Cable as Reinforcement in 3D Printed Concrete.

The Material Deposition Method (MDM) is enjoying increasing attention as an additive method to create concrete mortar structures characterised by a high degree of form-freedom, a lack of geometrical repetition, and automated construction. Several small-scale structures have been realised around the world, or are under preparation. However, the nature of this construction method is unsuitable for conventional reinforcement methods to achieve ductile failure behaviour. Sometimes, this is solved by combining p...

Bio-mimicking the underwater sensors has tremendous potential in soft robotics, under water exploration and human interfaces. Pinniped are semiaquatic carnivores that use their whiskers to sense food by tracking the vortices left by potential prey. To detect and track the vortices inside the water, a fully 3D printed pinniped inspired multi-material whisker sensor is fabricated and characterized. The fabricated whisker is composed of a polyurethane rod with a length-to-diameter ratio (L/d) of 20:1 with four...

Osseointegration of 3D printed microalloyed CoCr implants - addition of 0.04% Zr to CoCr does not alter bone material properties.

Electron beam melting (EBM) is a 3D printing technique for the production of metal structures where complex geometries with interconnected porosities can be built. Incorporation of as little as 0.04% Zr into the CoCr alloy can significantly improve the biomechanical anchorage of constructs fabricated by EBM. Here we investigate bone material properties, including microstructure and composition, adjacent to 3D printed CoCr implants with and without addition of 0.04% Zr, after 8 weeks of healing in the rabbit...

Break Scrub to Take That Phone Call?

The American College of Surgeons reports that 60% of the hundreds of thousands of surgical site infections occurring annually are preventable. The practice of surgeons taking phone calls while remaining sterile in the operating field is often accomplished by interposing a sterile disposable towel between the phone and their glove. After completing the call, surgeons resume operating. The purpose of our study is to test the conceptual idea of whether bacteria transmit from an inanimate object, such as a tele...

Using cell phone location to assess misclassification errors in air pollution exposure estimation.

Air pollution epidemiologic and health impact studies often rely on home addresses to estimate individual subject's pollution exposure. In this study, we used detailed cell phone location data, the call detail record (CDR), to account for the impact of spatiotemporal subject mobility on estimates of ambient air pollutant exposure. This approach was applied on a sample with 9886 unique simcard IDs in Shenzhen, China, on one mid-week day in October 2013. Hourly ambient concentrations of six chosen pollutants ...

Soft Robotic Manipulation and Locomotion with a 3D Printed Electroactive Hydrogel.

Electroactive hydrogels (EAH) which exhibit large deformation in response to an electric field have received great attention as a potential actuating material for soft robots and artificial muscle. However, their application has been limited due to the use of traditional two-dimensional (2D) fabrication methods.
