Antiferrodistortive and ferroeletric phase transitions in freestanding films of SrTiO3
Epitaxially grown thin films are commonly used to strain engineer electronic properties by the choice of a substrate, and therefore do not match bulk properties (leading to properties that deviate from the bulk material). Free standing ultrathin oxide films are expected to preserve the bulk-like properties due to the absence of substrate influence. However, we show that this expectation is not fulfilled with ultrathin free standing SrTiO3, as they get ferroelectric at 80K.

Novel Photoresist Chemistry Enables Lithography Approaching Angstrom-Scale Resolution
Photoresist materials are crucial in the manufacturing of computer chips, where the circuits are initially printed in the photoresist using photolithography. As the demand for smaller and more precise circuitry in computer chips grows, photoresists must resolve features with smaller sizes and higher density. One of the factors determining the ultimate resolution in lithography is the molecular size/mass of the photoresists.
