The reversible phase transitions in phase-change memory devices can switch on the order of nanoseconds, suggesting a close structural resemblance between the amorphous and crystalline phases. Despite this, the link between crystalline and amorphous tellu
The IR spectra of these gels, in the Si–O bond stretching region, shows that their structure strongly depends on theH2O/TEOSratio. The relative change in intensity of the Si–O stretching modes, in samples prepared using differentH2O/TEOSratios, are interpreted in terms of different degrees ...

Here we present the use of silicon nitride substrates as a means to overcome some of these obstacles. These substrates consist of a thin (typically 100 nm) layer of amorphous, low-stress silicon nitride grown onto a silicon wafer. Direct imaging of the local polymer morphology requires a subst...
For these reasons, nowadays, this ground-breaking inorganic class of amorphous alumina-silicate materials are drawing the attention of the world researchers for designing them as adsorbents for water and wastewater treatment where the chemical nature and structure of the materials have a great impact ...
Local secondary structure of KcsAM was determined using the well-established correlation between backbone 13C chemical shifts and torsion angles (Fig. 1, Fig. 2). The four helical domains present in KcsATET[2] are observed to also be present in KcsAM: TM1 (residues 27–50), the pore ...
MTSS, or Multi-Tiered System of Supports, is a framework that supports student academic, behavioral, and social-emotional learning (SEL) with a system of tiered interventions that meet student needs with personalized strategies. The goal of MTSS in education is to use complete data to enact the...
3b, the IR limit for longitudinal waves is reached for frequencies as small as ≈ 2 THz, which is quite smaller than those of amorphous silicon and silicon carbide, whose values are ≈ 8.5 THz and ≈ 9 THz, respectively50. This fact suggests that the contribution of ...
