However, many biopolymers, such as nucleic acids, polysaccharides, and proteins, cannot be readily constructed into a desired 3D shape at the submicron- or nanoscale due to their inherent rheological and structural properties. Can we truly achieve the free-form and high-resolution structuring of various biomolecules using 3D printing technology? https://phys.org/news/2023-04-era-3d-dnas-proteins.html Biochemistry Wed, 12 Apr 2023 15:56:03 EDT news600533761 To realize true Internet of Things in future, compact monolithic integrated micro-supercapacitors (MIMSCs) with high systemic performance along with cell number density will become indispensable for powering miniaturized electronics, but their scalable production is still challenging.

In fact, conventional medicines tend to be based on adult doses, so pediatric and elderly patients require doses tailored to their age. What is more, certain groups of patients also need specific dosage form alternatives to facilitate the oral administration of drugs. In this respect, rapidly disintegrating tablets are emerging as a good option as they dissolve the moment they are placed on the tongue. Another challenge pharmaceutical companies need to address is the controlled release of the drug over time, especially when the drug is of a hydrophobic type (i.e., when dissolving it in water poses problems). https://phys.org/news/2022-08-3d-starch-personalized-medicine.html Biochemistry Thu, 25 Aug 2022 14:35:02 EDT news580656901 3-D printing technology enables economies to produce goods locally, so conventional wisdom has been that it would dramatically reduce international trade; however, new University of California San Diego and World Bank research presents robust evidence that 3-D printing expanded trade. https://phys.org/news/2022-08-3d-positive-effects-global.html Economics & Business Wed, 17 Aug 2022 02:39:46 EDT news579922770 Anne S.

The traditional method for device fabrication is based on a multistep approach to construct energy devices, which can present challenges during fabrication, scalability and durability. To overcome these restrictions, Jingxin Zhao and a team of scientists in physics, electrochemical energy, nanoscience, materials, and chemical engineering in China, the U.S., and Singapore, developed an all-in-one coaxial fiber-shaped asymmetric supercapacitor (FASC) device. The team used direct coherent multi-ink writing, three-dimensional (3-D) printing technology by designing the internal structure of the coaxial needles and regulating the rheological property and feed rates of the multi-ink. The device delivered a superior areal energy and power density with outstanding mechanical stability. The team integrated the fiber-shaped asymmetric supercapacitor (FASC) with mechanical units and pressure sensors to realize high performance and self-powered mechanical devices to monitor systems.
