Semiconducting Single‐Wall Antimony Oxide Nanotubes and Oxidotritelluridoantimonate(V) Anions

Chemistry – A European Journal, EarlyView.
Antimony(V) binds directly to tellurium(−II) in the (SbOTe3)3− anion. The latter has been found between Sb2O3 nanotubes in a microporous cetineite structure. The Sb2O3 nanotube is positively polarized on its outer surface and negatively polarized on its inner surface, corresponding to a cylindrical capacitor. Substantial charge transfer from the anions

Application of Ultrasonic Sensors for Determining the Height of Dynamic Two‐Phase Layers in Tray Columns

Chemie Ingenieur Technik, EarlyView.
Ultrasonic sensors are evaluated for their applicability in dynamic gas–liquid systems. By comparing sensor data with two independent optical reference methods, their robustness and reliability are demonstrated under varying flow conditions and tray geometries in column systems.

Hybrid machine learning and genetic algorithm approach for catalyst and process optimization in Fischer–Tropsch synthesis toward sustainable fuel production

The Canadian Journal of Chemical Engineering, EarlyView.
Graphical representation of a data‐driven framework for Fischer‐Tropsch synthesis (FTS) modelling and optimization. Abstract This study presents a data‐driven approach for predicting the relationships between catalyst design, process conditions, and product selectivity in Fischer–Tropsch synthesis (FTS).

Application of artificial neural network and general machine learning modelling on CO2 adsorption in moisture equilibrated South African high and medium rank coals

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract This study investigates the effect of moisture on CO2 adsorption in South African coals using both experimental and machine learning approaches. Three coal samples (SL, TN, and EM) with varying ranks (RoVmr: 3.49%, 1.26%, and 0.64%, respectively) were collected from different regions of South Africa.

Stochastic Gradient Descent in High Dimensions for Multi‐Spiked Tensor PCA

Communications on Pure and Applied Mathematics, EarlyView.
ABSTRACT We study the high‐dimensional dynamics of online stochastic gradient descent (SGD) for the multi‐spiked tensor model. This multi‐index model arises from the tensor principal component analysis (PCA) problem with multiple spikes, where the goal is to estimate the unknown signal vectors within the N$N$‐dimensional unit sphere through maximum ...

Ten‐Year Public Expenditure Savings Associated with TNF Inhibitor Biosimilars under Australia's Pharmaceutical Benefits Scheme

Clinical Pharmacology &Therapeutics, EarlyView.
Biologic therapies are a major and growing driver of pharmaceutical expenditure globally, with tumor necrosis factor (TNF) inhibitors among the most widely used and costly biologics. In Australia, these therapies are funded through the Pharmaceutical Benefits Scheme (PBS), where biosimilars offer lower cost alternatives; however, the long‐term public ...
