Abstract: A transparent article is described herein that includes: a glass-ceramic substrate comprising first and second primary surfaces opposing one another and a crystallinity of at least 40% by weight; and an optical film structure disposed on the first primary surface. The optical film structure comprises a plurality of alternating high refractive index (RI) and low RI layers and a scratch-resistant layer. The article also exhibits an average photopic transmittance of greater than 80% and a maximum hardness of greater than 10 GPa, as measured by a Berkovich Hardness Test over an indentation depth range from about 100 nm to about 500 nm. The glass-ceramic substrate comprises an elastic modulus of greater than 85 GPa and a fracture toughness of greater than 0.8 MPa·?m. Further, the optical film structure exhibits a residual compressive stress of ?700 MPa and an elastic modulus of ?140 GPa.

Abstract: The present disclosure includes a construct comprising a leupeptin biosynthesis operon, the operon comprising leupA, leupB, leupC, and leupD genes operably linked to a promoter. Also included are cells comprising the construct, and methods for production of leupeptin peptide.

Abstract: A mounting assembly for a photovoltaic (PV) module, and systems including such mounting assemblies, are described. In an example, the mounting assembly includes a top support and a bottom support having respective mounting walls, and holes through the mounting walls. A pin assembly may extend through the holes in the mounting walls to constrain the supports, for example, relative to a torque member of a solar-tracking PV system. The pin assembly may include end collars to engage and distribute loading from the torque member.

Abstract: A mounting assembly for a photovoltaic (PV) module, and systems including such mounting assemblies, are described. In an embodiment, the mounting assembly includes a top strut to support a PV module, and a retainer fixed relative to the top strut. The retainer may have an upright and retaining tab portion forming a receiving gap to receive the PV module. The retainer may constrain movement of the PV module mounted on the top strut.
