Sn‐Driven Grain Boundary Elimination for Single‐Crystalline Ni‐Rich Cathodes with Superior High‐Voltage Stability in Lithium‐Ion Batteries

Advanced Science, EarlyView.
A low‐temperature synthesis method of single‐crystalline NCA was successfully achieved by Sn doping, employing the same synthetic conditions as its polycrystalline counterparts. This synthesis was conducted at a temperature that was 150 °C lower than that required for synthesizing single‐crystalline NCA without Sn doping.

Otimização do uso de sol de sílica como agente ligante para concretos refratários

Cerâmica, 2006
Várias pesquisas têm sido dedicadas à área de novos agentes ligantes para concretos refratários visando a substituição do cimento de aluminato de cálcio (CAC). Embora seja um dos agentes ligantes mais utilizado, o CAC apresenta uma série de desvantagens,

Printing‐Assisted Integration of Thermal, Fluidic and Electrical Components in Implants for Focal Brain Cooling

Advanced Science, EarlyView.
Extrusion‐based 3D printing of silicones and discrete electronic components are combined to create cortical implants for rodents that integrate thermal neuromodulation and electrical recording. Linked to an autonomous auxiliary driver unit, the system enables rapid, stable and localized hypothermia alongside ECoG recording.

Mechanochemical Engineered Sulfur Copolymers Onto Group 13 and Related Fillers Through Lewis Acid‐Base Pairing

Advanced Science, EarlyView.
Green mechanochemical copolymerization was developed for universal interfacial modification of Group 13 and related fillers. By leveraging Lewis acid–base coordination to anchor sulfur‐containing polymers—validated via multiscale characterization and DFT—this versatile method boosts performance across liquid fuels, thermal‐shielding materials, and ...

An Indicator‐Based Decision Framework for Circular Bioeconomy Transition in the Steel Industry: Integrating Multiphase Learning and Cooperative Game Modelling

Business Strategy and the Environment, EarlyView.
ABSTRACT Despite growing attention to the circular bioeconomy (CBE), the steel industry currently lacks a standardised, sectoral measurement framework to facilitate a low‐carbon transition. In this study, a decision‐support framework for evaluating CBE performance in the steel industry is proposed.

Synthesis of mullite aggregates from fly ash: effect on thermomechanical behaviour of low cement castables [PDF]

, 2004
Refractory aggregates were synthesised from beneficiated fly ash by reaction sintering with calcined alumina at 1600°C, and 83% mullite yield was achieved. The aggregates had low porosity, low thermal expansion and good refractoriness.

Impacto do uso de fibras poliméricas no desempenho de concretos refratários aplicados por projeção Influence of the polymeric fibers on shotcrete refractory castables

Cerâmica, 2004
A utilização de fibras poliméricas em concretos refratários tem sido motivada principalmente pela possibilidade de se elevar a velocidade de secagem sem acentuar o risco de explosão destes materiais. As fibras quando empregadas em concretos aplicados por

Clinical Anatomy of the Left and Right Atrial Appendages in Humans: Comparative and Developmental Perspective

Clinical Anatomy, EarlyView.
ABSTRACT Human atrial chambers derive from distinct embryonic anlagens, the original embryonic atria gradually transforming into the so‐called auricles, or atrial appendages. This study quantifies macroscopic variations in pectinate muscle architecture in human atrial appendages and evaluates their visualization using clinical imaging modalities.
