Influence of ordered L1₂ precipitation on strain-rate dependent mechanical behavior in a eutectic high entropy alloy

Description: This article focuses on Al0.7CoCrFeNi, a lamellar dual-phase (fcc + B2) precipitation-strengthenable eutectic high entropy alloy. The back-stresses from the coherent L12 precipitate were insufficient to cause improvement in twin nucleation, owing to elevated twinning stress under quasi-static testing. However, under dynamic testing high density of twins were observed.

Multiple levers for overcoming the recalcitrance of lignocellulosic biomass

Description: The article evaluates the impacts of physical, chemical and genetic interventions to improve biomass processing singly and in combination. Based on their results and literature studies, some form of non-biological augmentation will likely be necessary for the foreseeable future to achieve high total carbohydrate solubilization (TCS) for most cellulosic feedstocks. The results show that this need not necessarily involve thermochemical processing, and need not necessarily occur prior to biological conversion.

Multimodal switching of a redox-active macrocycle

Description: This article looks at molecules that can exist in multiple states with the possibility of toggling between those states based on different stimuli. They have potential for use in molecular switching or sensing applications. The coupling of two different oxidation states with two different charge-transfer states within one macrocyclic scaffold delivers up to five different optical outputs. This molecular switching manifold exploits intramolecular coupling of multiple redox active substituents within a single molecule.

Badly approximable points on self-affine sponges and the lower Assouad dimension

Description: This article highlights a connection between Diophantine approximation and the lower Assouad dimension by using information about the latter to show that the Hausdorff dimension of the set of badly approximable points that lie in certain non-conformal fractals, known as self-affine sponges, is bounded below by the dynamical dimension of these fractals. The results, which are the first to advance beyond the conformal setting, encompass both the case of Sierpiński sponges/carpets (also known as Bedford–McMullen sponges/carpets) and the case of Barański carpets.

Rate Coefficient Measurements and Theoretical Analysis of the OH + (E)‑CF₃CH==CHCF₃ Reaction

Description: Rate coefficients, k, for the gas-phase reaction of the OH radical with (E)CF3CHCHCF3 ((E)-1,1,1,4,4,4-hexafluoro-2-butene, HFO-1336mzz(E)) were measured over a range of temperatures (211−374 K) and bath gas pressures (20−300 Torr; He, N2) using a pulsed laser photolysis−laser-induced fluorescence (PLP−LIF) technique. k1(T) was independent of pressure over this range of conditions with k1(296 K) = (1.31 ± 0.15) × 10−13 cm3 molecule−1 s−1 and k1(T) = (6.94 ± 0.80) × 10−13exp[−(496 ± 10)/T] cm 3 molecule−1 s−1, where the uncertainties are 2σ, and the pre-exponential term includes estimated systematic error. Rate coefficients for the OD reaction were also determined over a range of temperatures (262−374 K) at 100 Torr (He). The OD rate coefficients were ∼15% greater than the OH values and showed similar temperature dependent behavior with k2(T) = (7.52 ± 0.44) × 10−13exp[−(476 ± 20)/T] and k2(296 K) = (1.53 ± 0.15) × 10−13 cm3 molecule−1 s−1. The rate coefficients for reaction 1 were also measured using a relative rate technique between 296 and 375 K with k1(296 K) measured to be (1.22 ± 0.1) × 10−13 cm3 molecule−1 s−1, in agreement with the PLP−LIF results. In addition, the 296 K rate coefficient for the O3 +( E)CF3CHCHCF3 reaction was determined to be <5.2 × 10−22 cm3 molecule−1 s−1. A theoretical computational analysis is presented to interpret the observed positive temperature dependence for the addition reaction and the significant decrease in OH reactivity compared to the (Z)-CF3CHCHCF3 stereoisomer reaction. The estimated atmospheric lifetime of (E)-CF3CH CHCF3, due to loss by reaction with OH, is estimated to be ∼90 days, while the actual lifetime will depend on the location and season of its emission. Infrared absorption spectra of (E)-CF3CHCHCF3 were measured and used to estimate the 100 year time horizon global warming potentials (GWP) of 32 (atmospherically well-mixed) and 14 ...

Further Analysis on Solubility Measurement and Thermodynamic Modeling of Benzoic Acid in Monosolvents and Binary Mixtures

Description: Article discussing further analyses of the recent report (by Sandeepa et al.) on the solubility of benzoic acid in six monosolvents (i.e. tributyl phosphate, diacetone alcohol, methyl-n-propyl ketone, methyl acetate, amyl acetate, and isooctane) and five binary systems (i.e. ethanol + hexane, isopropyl alcohol + hexane and chloroform + hexane, acetone + hexane, and acetone + water) along with some numerical analyses. The reported calculations have been reanalyzed based on combined nearly ideal binary solvent/Redlich-Kister, the modified Wilson model, general single model, Jouyban–Acree model and Jouyban–Acree–van’t Hoff model. The investigated models provide good estimation of the solubility behavior of benzoic acid in the binary solvent mixtures at various temperatures.

The First Stalin Mass Operation (1927)

Description: This article based on new archival documents introduces a new episode of mass operations, which took place in June and July of 1927 and was directed against the broad group of “anti-Soviet” forces. It preceded many practices of mass terror of the 1930s with judicial and extra-legal mechanisms. The goal of this article is to explain motivations, justifications, and mechanisms of this repressive campaign and to put this episode in the wider context of Soviet terror. Facing the combination of a perceived danger of war and real internal social hostility expressed in broad defeatism, both threatening the perpetuation of their governmental powers, authorities resorted to repressions. The 1927 episode highlights the factor of a perceived threat of war as a crucial motivating element in Soviet repressive tactics.

Technical Memorandum: Lewisville Lake Watershed Protection and Management Strategies

Description: With a current population of just over half a million and a 2030 projected population of approximately one million, expansion throughout Denton County shows no sign of slowing down (NCTCOG). Increasingly, freshwater resources are also facing increased pressure from this urban expansion. Effective assessment and management techniques are necessary to protect the diversity of ecosystem services found within fluvial ecosystems and to mitigate current and future conditions of environmental stressor amplified by urban development. The use of various spatial analysis techniques in environmental assessment present more expedient, cost effective, and broader ranging methods of evaluation than traditional field techniques. One such novel evaluation technique is the Water Quality Corridor Management (WQCM) model, developed by the University of North Texas in cooperation with the Upper Trinity Regional Water District (UTRWD). The WQCM model is a geospatial database that utilizes GIS and remote sensing techniques to assess and prioritize stream reaches according to their overall health and sustainability. This project assessed the viability of the WQCM model in reviewing the status of stream systems, and ultimately, established an accurate mechanism for evaluating the stream corridor and surface water quality draining into Lewisville Lake, a popular recreation site and drinking water source for the urbanizing Dallas and Fort Worth metropolitan area.
