Stabilizing large pores Zeolites with very cages, such as zeolite Y, are rare but extremely useful in processing the hydrocarbons petroleum. Lee et al. report a route for preparing thermally stable forms of large-cage phosphate-based molecular sieves UCSB-6 and UCSB-10 (see Perspective by Xie). They used mainly sodium cesium ions inorganic structure-directing agents, along an organic molecule, ...

We determined the structure of the rhodopsin mutant N2C/D282C expressed in mammalian cells; the first structure of a recombinantly produced G protein-coupled receptor (GPCR). The mutant was designed to form a disulfide bond between the N terminus and loop E3, which allows handling of opsin in detergent solution and increases thermal stability of rhodopsin by 10 deg.C. It allowed us to crystalli...

Different density rhodium nanoparticulate substrates were fabricated by electron-beam physical vapor deposition in order to study the fluorescence of close-proximity fluorophores to the high thermally stable rhodium nanoparticles. We observed an apparently constant metal-enhanced fluorescence (MEF), when fluorophores were placed in close proximity to rhodium nanoparticles before and after autoc...

Design of thermally stable proteins is spurred by their applications in bionanotechnology. There are three major issues governing this: first, the upper limit on the temperature at which proteins remain physiologically active and are available for technological applications (answers may emerge from the discovery of new, natural hyperthermophilic enzymes that are active above 125 degrees C or fr...

One of the challenges to increasing the mass of a white dwarf through accretion is the tendency for the accumulating hydrogen to ignite unstably and potentially trigger mass loss. It has been known for many years that there is a narrow range of accretion rates for which the hydrogen can burn stably, allowing for the white dwarf mass to increase as a pure helium layer accumulates. We first revie...

The preparation of nanocellulose fibers (NFs) is achieved through pretreating cellulose in a NaOH/urea/thiourea solution, and then defibrillating the fibers through ultrasonication, resulting in a high yield of 85.4%. Extensive work has been done to optimize the preparation parameters. The obtained NFs are about 30 nm in diameter with cellulose II crystal structure. They possess high thermal st...

A general theory of thermally stable anisotropic laminates with bending-extension coupling is presented in the framework of linear thermo-elasticity. It is based upon the use of tensor invariants, found by the polar formalism for bi-dimensional anisotropic elasticity. The extension of the results to moisture absorption effects is also proved.

Thermally stable nanoporous organosilicate thin films were realized by the microphase separation of pore-generating polymers mixed with an organosilicate matrix to be antireflective coatings (ARCs), for which a thin film with a refractive index (n) of 1.23 for zero reflection is required. The refractive index of such nanoporous organosilicate films can be tuned from 1.39 down to 1.23 by incorpo...

Plant extracts are extensively researched as a source of green corrosion inhibitors. Herein, we report on a highly efficient and thermally stable corrosion inhibitor from the stem extract of high-altitude shrub Berberis aristata. The corrosion inhibition efficiency (IE) of the extract was tested in 1.0 M H2SO4 for the corrosion protection of mild steel (MS) by using gravimetric and electrochemi...
