We report a flexible and wearable pressure sensor based on the giant piezocapacitive effect of a three-dimensional (3-D) microporous dielectric elastomer, which is capable of highly sensitive and stable pressure sensing over a large tactile pressure range. Due to the presence of micropores within the elastomeric dielectric layer, our piezocapacitive pressure sensor is highly deformable by even ...

BACKGROUND Elastomeric pumps are often used to administer intravenous antibiotics in the outpatient setting, but effective infusion requires that the drug remain stable in solution throughout the procedure. OBJECTIVE To determine the chemical stability of ceftolozane/tazobactam when reconstituted and stored over an extended time in the AccuFlo (EMED Technologies, El Dorado Hills, California) ...

background: there have been numerous researches on elastomeric ligatures, but clinical conditions in different stages of treatment are not exactly similar to laboratory conditions. the aim of this in vitro study was to simulate clinical conditions and evaluate the effect of three stretching patterns on the amount of force, tensile strength (ts) and extension to ts of the elastomers during 8 wee...

Spiders spin intricate webs that serve as sophisticated prey-trapping architectures that simultaneously exhibit high strength, elasticity and graceful failure. To determine how web mechanics are controlled by their topological design and material distribution, here we create spider-web mimics composed of elastomeric filaments. Specifically, computational modelling and microscale 3D printing are...

patients  with  primary  antibody  deficiencies  (pad)  are  susceptible  to  recurrent  and chronic infections and a variety of complications. this study was performed to assess quality of life (qol) of pad patients who were under long term treatment and regular follow-up.thirty six adults with proved diagnosis of pad, who had received regular intravenous immunoglobulin replacement therapy, we...

ON THE EFFECTIVE BEHAVIOR, MICROSTRUCTURE EVOLUTION, AND MACROSCOPIC STABILITY OF ELASTOMERIC COMPOSITES

Objective: The objective of this present study was to understand how children and adolescents perceive esthetic attractiveness of a variety of orthodontic appliances. It also analyzed preferences according to patients' age, sex and socioeconomic status. Methods: A photograph album consisting of eight photographs of different orthodontic appliances and clear tray aligners placed in a consentin...

Multilayer elastomeric device fabrication by replication molding requires a method for bonding together layers. In our development of solvent-resistant microfluidics, the goal with each promising new material or coating was to fabricate multilayer chips to evaluate crossed-channel valve performance and ultimately to implement functional elastomeric devices. However, determining a reliable adhes...

every year large amounts of grapes are stores in normal and cold rooms to offer off-season of grapes to the market which based on several reasons their quality and weight greatly decreases. therefore, in order to decrease the post harvest losses of grapes and selection of suitable cultivars for long time storage, this study was conducted in two experiments, one in a factorial experiment based o...
