چکیده
We report the design of a multipass microrheometer that can be fully customizable at low cost and reasonable time, which allows us to perform experiments rapidly in broad range shear rates (i.e., from 0.1 100 s−1), using small amounts material just some milligrams). Additionally, low-cost approach opens for an easy parallelization setup makes it suitable high-throughput rheological experimentation polymer melts (HT-Rheo-E). The novel rheometer consists microchannel microcapillary or microslit) fluid flows driven by two controlled millimetric pistons (diameter 2 mm). Two piezoelectric miniaturized pressure sensors are placed entrance exit record drop across capillary during motion. current work reports with different cross sections microchannel, i.e., circular rectangular, measurements viscosity Newtonian non-Newtonian over wide less than 1 g sample. demonstrate measure viscoelastic properties polymers applying oscillatory flow. printed is potential interest applications quality control industrial production, natural systems (such as starch-based mixtures) academic research where rapid repeated limited milligrams required (e.g., biological systems).

Low-cost microbioreactor for high-throughput bioprocessing.
The design of a microbioreactor is described. An optical sensing system was used for continuous measurements of pH, dissolved oxygen, and optical density in a 2 mL working volume. The K(L)a of the microbioreactor was evaluated under different conditions. An Escherichia coli fermentation in both the microbioreactor and a standard 1 L bioreactor showed similar pH, dissolved oxygen, and optical de...
متن کاملNanofabrication at high throughput and low cost.
The task of nanofabrication can, in principle, be divided into two separate tracks: generation and replication of the patterned features. These two tracks are different in terms of characteristics, requirements, and aspects of emphasis. In general, generation of patterns is commonly achieved in a serial fashion using techniques that are typically slow, making this process only practical for mak...

متن کاملDeveloping a Cost-Effective Approach for Enhancing the Rheological and Mechanical Behavior of High Strength Self-Compacting Concrete
Despite the numerous advantages of using concrete with high strength capacity, the brittle behavior of high strength concrete (HSC) and higher production cost has limited its use in the construction industry. This research aims to develop a cost-effective approach for production of high strength self-compacting concrete with desirable performance in either compressive or tensile loading conditi...
