3D Printing Drug Manufacturing System

A new and compact drug manufacturing system, which relies on 3-D printing and chemical analysis software, has the potential to quickly and conveniently produce a variety of medications on-site. The advancement sidesteps many challenges that come with mass production of drugs at large-scale facilitates. For example, central drug manufacturing plants are costly to maintain and to repurpose for the production of different drugs. In contrast, the system created by Philip J. Kitson and colleagues yields a customized blueprint for drug synthesis using simple plastic modules that can easily be assembled on-site, at low cost. First, software is used to identify the chemical reactions and processes that are necessary for the desired drug, and then the ideal chambers and components of the system are created using a cheap 3-D printer (that costs about $2,000). In this study, the researchers chose to […]

Self-healing fungi concrete could provide sustainable solution to crumbling infrastructure

A new self-healing fungi concrete, co-developed by researchers at Binghamton University, State University of New York, could help repair cracks in aging concrete permanently, and help save America’s crumbling infrastructure. Congrui Jin, assistant professor of mechanical engineering at Binghamton University, has researched concrete and found that the problem stems from the smallest of cracks. “Without proper treatment, cracks tend to progress further and eventually require costly repair,” said Jin. “If micro-cracks expand and reach the steel reinforcement, not only the concrete will be attacked, but also the reinforcement will be corroded, as it is exposed to water, oxygen, possibly CO2 and chlorides, leading to structural failure.” These cracks can cause huge and sometimes unseen problems for infrastructure. One potentially critical example is the case of nuclear power plants that may use concrete for radiation shielding. While remaking a structure would replace […]
