Oxygen‐Driven Structural Reorganization by Trace Water Enabling Fast Li‐Ion Transport in a Pliable Solid Electrolyte

open access: yesAdvanced Energy Materials, EarlyView.
Trace water is acting as a constructive mediator in 2LiCl–GaF3, markedly increasing ionic conductivity while reorganizing local coordination. Hydration creates localized Li+ solvation environments and partially dissociates ion pairs, enhancing Li‐ion mobility.

Indirect calorimetry to estimate energy requirements for growing and finishing Nellore bulls

open access: yesJournal of Integrative Agriculture, 2017
Determination of nutritional requirements is the basis for diet formulation. The objectives of this study were to determine the net energy requirements for maintenance (NEm) and weight gain (NEg) in Nellore bulls during the growing and finishing phases ...

Population balance modeling and digital design of degree of agglomeration in industrial crystallization

open access: yesAIChE Journal, EarlyView.
Abstract This study presents a coupled population balance model (PBM) for describing the degree‐of‐agglomeration (DoA) in crystallization by independently tracking total particle and agglomerate number densities. Applied to an industrial active pharmaceutical ingredient, the model outperformed bridge‐counting methods and accurately captured DoA trends ...

A New Paradigm for Understanding the Rheology and Processability of Poly(p‐Phenylene Terephthalamide) Liquid‐Crystalline Solutions

open access: yesJournal of Applied Polymer Science, EarlyView.
Kevlar is traditionally modeled as a rigid‐rod polymer, yet rheological behavior deviates from this assumption. The review introduces a novel “twist‐tie” entanglement theory for aramid polymer chains in the nematic liquid crystal state, providing a molecular explanation for deviations from rigid‐rod models. Understanding twist‐tie entanglement dynamics

Characterizing Heterogeneity in Post‐Consumer Rigid PP Packaging Waste: Implications for Object and Property‐Based Flake Sorting

open access: yesJournal of Applied Polymer Science, EarlyView.
Commercial PP packaging grades span wide ranges in melt flow rate and stiffness, defining distinct application‐specific property spaces. Post‐consumer rigid PP products populate these spaces heterogeneously, with processing method and degradation shifting properties beyond virgin grade benchmarks.

Assessment of select direct and indirect pozzolanic reactivity test outcomes with robust regression and ranking analysis

open access: yesCase Studies in Construction Materials
The use of pozzolanic materials as a sustainable partial replacement option for portland cement in concrete has been extensively studied over the last few decades. This study aimed to assess the pozzolanic reactivity of seven different powdered materials:

Designing PLA/PHBV Implants With Degradation Matched to Normal or Inflammatory Tissues

open access: yesJournal of Applied Polymer Science, EarlyView.
PLA/PHBV blends are investigated under simulated normal and pathological conditions. Multivariate statistical analysis decouples the competing effects of water‐uptake‐driven hydrolysis and crystallinity‐imposed barriers. Melt‐state rheological parameters serve as structural probes linking phase morphology to degradation kinetics. A semi‐empirical model

Microwave‐Assisted Alcoholysis of Ethylene–Vinyl Acetate: Phenomenological and Thermal Evolution of EVAOH Terpolymers

open access: yesJournal of Applied Polymer Science, EarlyView.
Microwave‐assisted alcoholysis converts EVA into EVAOH terpolymers, promoting a progressive transition from EVA‐like crystallites to VOH‐rich hydrogen‐bonded crystalline domains. Solvent‐controlled swelling influences conversion kinetics, while thermal analysis reveals a sigmoidal increase in melting temperature that a two‐population crystallization ...

Energy expenditure measured by indirect calorimetry in a neuroscience intensive care unit: a retrospective observational study

open access: yesThe South African Journal of Clinical Nutrition
Objectives: To compare indirect calorimetry (IC) readings with the Harris–Benedict equation (HBE) predictions of resting energy expenditure (REE) in intubated acute brain-injured patients in a tertiary hospital’s Neuroscience Intensive Care Unit (ICU ...

Synergetic Heterophase and Selective Defect Engineering of Nano Multicomponent Alloys for Rechargeable Zn–Air Batteries

open access: yesCarbon Energy, EarlyView.
An fcc/bcc with defects (bcc‐d) MCA is designed by utilizing the interplay between heterophase and selective defect engineering and exhibits excellent electrocatalytic activity suitable for high‐performance zinc–air batteries. The synergistic catalysis of the fcc/bcc‐d breaks the universal linear‐scaling relationships of adsorbed multi‐intermediates ...
