Muscle Tissue Engineering in Fibrous Gelatin—Implications for Meat Analog

Written by Tianyu Liu

From gummy sugars, scientists can make meat, real meat! Yes, I'm not talking about vegan food. Luke MacQueen from Harvard University presented in Wednesday’s poster session of Symposium SB02 a strategy to synthesize meat in laboratories. What he needed was gelatin, a mixture of peptides and proteins generated by partial hydrolysis of collagen, and is the main component of gummy sugars.

Instead of gummy sugars, MacQueen and co-workers used gelatin to grow meat. The researchers adopted an immersion rotary jet spinning technique that quickly spun gelatin solutions into ethanol. Due to centrifugal force and rapid coagulation in methanol, the gelatin solution was converted into solid microfibers. These microfibers, owing to their excellent bio-compatibility, served as scaffolds for growing muscle cells into laboratory-made meat. When asked the flavor of this artificial meat, MacQueen said that he had not tried yet because of concerns on contamination during processing, but he was optimistic that this technology would revolutionize the future meat-manufacturing processes.


Poster Session Day III

Poster sessions are in full swing with researchers from all over the world showing their work. Enjoy the sessions with complimentary beverages and refreshments.  Yesterday, I talked to Zhenghong Dai, a 2nd year graduate student researcher from Brown University who is researching on the strain-stress effects of perovskite thin films. In his research, he has tried to understand the self-healing behavior of thin films which will help to increase flexibility and increase their use as solar cells.

Symposium EL04 : Emerging Chalcogenide Electronic Materials—From Theory to Applications

Jian-An Ke, Massachusetts Institute of Technology 

Resistless Patterning Techniques for Transition Metal Dichalcogenides (TMDs) 

Written by Tomojit Chowdhury 

“Polymer resists are detrimental to the device performance” – Jian-An Ke from the Gradecak group at MIT has been trying to resolve this issue created by polymer residues on semiconducting thin films (e.g., layered TMDs) in order to design and fabricate optoelectronic devices with minimum loss. In his poster, Ke demonstrated an alternative approach by creating patterns on a growth substrate by high-energy electron beam, which was then subjected to chemical vapor deposition in order to grow few-layer molybdenum disulfide (MoS2) crystals with a grain size on the order of 150 nm. Another part of his research is to preferentially grow MoS2 crystals on top of other exfoliated TMDs by the laser ablation method to create in plane and vertical TMD heterostructures with new optical properties.

Symposium FF04: Crystal Engineering of Functional Materials—Solution-Based Strategies

Minyuan Li, Los Alamos National Laboratory 

Solutional Nanoparticle Syntheses of Layered Ternary Copper Selenides of Mo/W 

Written by Tomojit Chowdhury 

Minyuan Li from Los Alamos National Laboratory reports two-dimensional nanocrystalline ternary selenides of copper (Cu2MSe4, where M = Mo or W). Powder x-ray diffraction (pXRD) and scanning transmission electron microscopy (STEM) verified the phase and stoichiometry of the ternary selenides. In addition, Raman spectroscopy indicated preservation of bonding characteristics in the reactants and the products. These materials have been implicated to be useful for water purification and energy storage purposes.

Poster Session FF01: Beyond Graphene 2D Materials – Synthesis, Properties and Device Applications

Written by Tomojit Chowdhury

The poster session on Monday night attracted a large number of scientists across all the subdisciplines of materials research. Poster presenters included graduate students, postdocs, research associates, and industry representatives all over the world. The two-dimensional (2D) materials section exhibited a wide variety of research works that contained rational synthesis of layered materials, cryogenic electron microscopic and scanning probe techniques, 2D non-linear optics (based on Janus layered materials), top-down fabrication of Moiré superlattices, quantum key distribution (single photon emission), and many more. Concurrently, the MRS best poster awardees presented some of the finest research works that deserves special mention. Congratulations to all the presenters for making the poster session a grand success!
