ABSTRACT Persistence of HCPs remains a major purification challenge in biopharmaceutical manufacturing with direct consequences for product quality, patient safety, and regulatory compliance. Over the last two decades, deeper insights into the mechanisms driving HCP persistence have clarified why certain proteins evade removal during purification ...

A SOC equilibrium control strategy for MMC-SCES based on capacitor voltage balancing
The super capacitor energy storage (SCES) system based on modular multilevel converter (MMC) is one of the key technologies for addressing issues with the grid integration of large-scale renewable energy.

The effect of reagents on the structure and performance of sodium‐layered oxides has not yet been thoroughly studied. This work explored this factor systematically through in situ high‐temperature XRD. The samples synthesized via MnCO3‐based precursors form the Li2MnO3 phase at evaluated temperature and perform better than those through MnO2‐based ...

Research on a small-signal stability criterion for MMC controller
High voltage direct current (HVDC) transmission based on modular multilevel converter (MMC) is widely used in large-scale renewable energy delivery. However, the lagged inertia of MMC controllers may undermine the small-signal stability.

Herein, we propose a straightforward and efficacious strategy of surface modification for P2‐type Na0.7Li0.03Mg0.03Ni0.27Mn0.6Ti0.07O2 cathode in high‐voltage Na‐ion batteries. The stable amorphous SiO2 coating layer on the cathode surface contributes to a strong, dense, fluorine and silicon‐rich cathode–electrolyte interphase, which inhibits the side ...

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

Revisiting the synthesis of dimethyl carbonate from methanol and carbon dioxide
Abstract The process for producing dimethyl carbonate (DMC) from carbon dioxide (CO2) and methanol is explored in this article. It provides an overview of the thermodynamics involved in DMC synthesis, discussing the challenges and potential solutions. The article highlights the reported use of catalysts and dehydrating agents to improve DMC yield and ...

Longitudinal Clinical Progression in X‐Linked Adrenoleukodystrophy: The AMNL Scoring System
ABSTRACT Objective The current clinical nomenclature for individuals with ABCD1 gene dysfunction is often uninformative. The disorder was initially described as a combination of adrenal insufficiency and leukodystrophy, leading to the widespread use of “X‐linked adrenoleukodystrophy” (ALD).
