Abstract:
... In our original paper (Buono et al., 2020), we investigated the dynamics of degassing (e.g., bubble nucleation and growth, degassing styles and regimes) of H₂O-, CO₂- and H₂O-CO₂-rich evolved alkaline melts over a wide range of variables (final pressures, decompression rates, volatile compositions and contents, temperatures) through a comprehensive review of previous and new HP (high pressure)-HT ...

Abstract:
... The Kremer–Grest (KG) model is a standard for studying generic polymer properties. Here we have equilibrated KG melts up to and beyond 200 entanglements per chain for varying chain stiffness. We present methods for estimating the Kuhn length corrected for incompressibility effects, for estimating the entanglement length corrected for chain stiffness, and for estimating bead frictions and Kuhn time ...

Abstract:
... The entanglement length Nₑ is a key parameter for all entangled polymer fluids for which no comprehensive scaling theory yet exists. We have pieces of a theory; the Lin-Noolandi (LN) argument predicts Nₑ scaling for flexible chains that agrees with data on polymer melts. There are arguments for how Nₑ should depend on polymer concentration, but which are not obviously consistent with LN. Morse sca ...

Abstract:
... Freeze casting technique has become a promising way to assemble various components into multifunctional nacre-like materials. Surprisingly, although many ceramics materials have been processed by this approach, there are few studies reporting the structure–property-processing relationships of freeze-cast porous B₄C ceramics. Here we generate bimodally lamellar porous B₄C scaffolds by freeze castin ...

Three different wall materials are tested: hardened glass, ice and Acrylonitrile butadiene styrene (ABS) polymer. The results show a high sensitivity to impact velocity Vᵢ, where eₙ decreases rapidly with increasing Vᵢ. The resul ...

In this paper, novel amide linked 1,2,3-triazoles containing aryloxy derivatives (8a–l) are synthesized via copper-catalyzed one-pot sequential hydroxylation-O-alkylation/click reaction of 2-bromo-N-prop-2-ynyl-benzamides. The products are synthesized in an efficient way in high isolated yields. The synthetic method involves the use of 2-bromo-N-prop-2-ynyl-benzamide and various benzyl halides ove ...

Abstract:
... Two-thirds of the global nickel output can be attributed to the rotary kiln-electric furnace process. Due to the high contents of MgO and SiO₂ in laterite, a high temperature (∼1600 °C) and corresponding energy (approximately 14 GJ/t-ferronickel) are required during the electric furnace smelting. This work verifies the feasibility of decreasing the smelting temperature by controlling the slag form ...

We show that under relevant processing conditions, isotactic poly(butene-1) (iPB-1) directly crystallizes into the thermodynamically stable form I and III from the melt state when it is confined in nanocylinder shape domains. The iPB-1 nanofibers with an average diameter of about 200 nm confined in an incompatible polyethylene (PE) matrix show the kinetically favored form II in addition to form I. ...

Abstract:
... Melts of long-chain polar amphiphiles do not wet polar substrates (autophobic) due to the formation of a monolayer that lowers the surface energy of the substrate. The monolayer adsorbed onto the substrate melts at a temperature (Tₛ) much higher than the bulk melting temperature (Tₘ) on account of strong headgroup–substrate interactions. Contrary to our expectation, namely, that strongly binding h ...

It can distinguish the nucleation and crystal growth processes unequivocally, especially in the early nucleation stage, which can hardly be followed by other traditionally used techniques owing to the limited amount of the transformed form I crystals. Moreover ...

Abstract:
... Granitic magmas extracted from crustal sources can form over a wide variety of P, T and aH₂O conditions. Both fluid-present and effectively fluid-absent conditions can yield granitic magmas, though the majority are formed through high-T, fluid-absent reactions because, in the deep crust, most available H₂O within rock bodies is contained within minerals rather than in free fluids. Fluid-present pa ...

However, non-crystalline MOFs (amorphous MOFs, MOF liquids, and MOF glasses) are starting to emerge as alternative materials, beyond the dictatorial domain of crystalline MOFs. Non-crystalline MOFs present many opportunities, either as novel functional materials themselves, or as vehicles to create ...
