Starting it Early

Thursday's poster session saw a huge participation, a specific section where students currently in their high school showed their research work. It's heartening to see the material science enthusiasts starting so early. Interviewing a couple of them, I found out that the projects were mostly their summertime projects which were aimed for them to get a hang of the subject. 

Mr Sovesh Mohapatra hails from Jaipur, and has been doing research in various fields for the last few years. He collaborated with Dr Satapathi's Lab from the Department of Physics IIT Roorkee where his research aims in growing lead-free single crystal using inverse temperature crystallization method. 

Ethan and Jack from South Side High School and Hewlett High School researched on mixed cation perovskites which included preliminary characterization of perovskites thin films composed from them, as well as stability studies to determine their applicability as thin films for optoelectronic applications. 

We sincerely hope that MRS keeps giving these young chaps a chance to showcase their research and encourage them from such a young age.

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.

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.
