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? /news/2023-04-era-3d-dnas-proteins.html Biochemistry Materials Science 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.

While rocket science helps deliver the spacecraft to the moon, other areas of science are needed to sustain life and enable activities during trips to the moon and while on the lunar surface. Experiments aboard the International Space Station serve as the basis for much of that science and are helping lay a foundation for the Artemis missions. /news/2022-12-space-station-solutions-artemis-missions.html Space Exploration Mon, 12 Dec 2022 16:44:26 EST news590085857 A method to convert a commonly thrown-away plastic to a resin used in 3D-printing could allow for making better use of plastic waste. /news/2022-08-plastic-valuable-products.html Materials Science Wed, 31 Aug 2022 11:53:03 EDT news581165581 Traditional methods produce medicines with specific parameters, but in many cases without meeting the individual needs of patients. 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). /news/2022-08-3d-starch-personalized-medicine.html Biochemistry Materials Science 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. /news/2022-08-3d-positive-effects-global.html Economics & Business Wed, 17 Aug 2022 02:39:46 EDT news579922770 Anne S.
