Cryo-STEM mapping of solid–liquid interfaces and dendrites in lithium-metal batteries

Cryo-STEM mapping of solid–liquid interfaces and dendrites in lithium-metal batteries

Solid–liquid interfaces are important in a range of chemical, physical and biological processes but are often not fully understood owing to the lack of high-resolution characterization methods that are compatible with both solid and liquid components. For example, the related processes of dendritic deposition of lithium metal and the formation of solid–electrolyte interphase layers are known to be key determinants of battery safety and performance in high-energy-density lithium-metal bat...

UCSF School of Dentistry uses Avizo software to extract changes in periodontal ligament space and tooth movement due to orthodontic therapy

UCSF School of Dentistry uses Avizo software to extract changes in periodontal ligament space and tooth movement due to orthodontic therapy

During the acts of biting and chewing, the muscles of the jaw (consisting of the masseter, temporalis, and medial pterygoid in the elevator group, and lateral pterygoid as the main depressor) generate forces that dictate jaw kinematics . The movement of jaws hinges about the temporomandibular joint and are brought together by the muscles attached to respective bones through bone-tendon interfaces known as entheses . Thus, chewing forces affect aspects of craniofacial structure as well as bo... Read more

Advances in the Synthesis and Long‐Term Protection of Zero‐Valent Iron Nanoparticles

Advances in the Synthesis and Long‐Term Protection of Zero‐Valent Iron Nanoparticles

Core@shell Fe@Fe3O4 nanoparticles (NPs) are synthesized via the thermal decomposition of iron pentacarbonyl (Fe(CO)5) in the presence either of oleylamine (OAm) or a mixture of OAm and oleic acid (OA). The heterostructured nanocomposites formed do so by a postsynthetic modification of isolated Fe seeds. This proves the versatility of the coating procedure and represents a significant advantage over previous work with Co seeds owing to the higher magnetic susc... Read more

REGIONAL DIVERSITY IN THE MURINE CORTICAL VASCULAR NETWORK IS REVEALED BY SYNCHROTRON X-RAY TOMOGRAPHY AND IS AMPLIFIED WITH AGE

REGIONAL DIVERSITY IN THE MURINE CORTICAL VASCULAR NETWORK IS REVEALED BY SYNCHROTRON X-RAY TOMOGRAPHY AND IS AMPLIFIED WITH AGE

Cortical bone is permeated by a system of pores, occupied by the blood supply and osteocytes. With ageing, bone mass reduction and disruption of the microstructure are associated with reduced vascular supply. Insight into the regulation of the blood supply to the bone could enhance the understanding of bone strength determinants and fracture healing. Using synchrotron radiation-based computed tomography, the distribution of vascular canals and osteocyte lacunae was assessed in murine cortica... Read more

Real time, in-situ deuteriding of uranium encapsulated in grout; effects of temperature on the uranium-deuterium reaction

Real time, in-situ deuteriding of uranium encapsulated in grout; effects of temperature on the uranium-deuterium reaction

To accurately predict the initiation and evolution of uranium hydride potentially present in nuclear waste containers, studies of simulated conditions are required.

Here, for the first time, the uranium-deuterium reaction was examined in-situ, in real time, whilst within grouted media. A deuterium gas control rig and stainless steelquartz glass reaction cell were configured on a synchrotron beam line to collect X-ray diffraction and X-ray tomography data. It was found that deuteride fo... Read more

Automatic method for estimation of in situ effective contact angle from X-ray micro tomography images of two-phase flow in porous media

Automatic method for estimation of in situ effective contact angle from X-ray micro tomography images of two-phase flow in porous media

Multiphase flow in porous media is strongly influenced by the wettability of the system, which affects the arrangement of the interfaces of different phases residing in the pores.

We present a method for estimating the effective contact angle, which quantifies the wettability and controls the local capillary pressure within the complex pore space of natural rock samples, based on the physical constraint of constant curvature of the interface between two fluids. This algorithm is ... Read more

Impact of Pore Tortuosity on Electrode Kinetics in Lithium Battery Electrodes: Study in Directionally Freeze-Cast LiNi0.8Co0.15Al0.05O2 (NCA)

Impact of Pore Tortuosity on Electrode Kinetics in Lithium Battery Electrodes: Study in Directionally Freeze-Cast LiNi0.8Co0.15Al0.05O2 (NCA)

The prevailing electrode fabrication method for lithium-ion battery electrodes includes calendering at high pressures to densify the electrode and promote adhesion to the metal current collector.

However, this process increases the tortuosity of the pore network in the primary transport direction and imposes severe tradeoffs between electrode thickness and rate capability. With the aim of understanding the impact of pore tortuosity on electrode kinetics, and enabling cell designs with ... Read more
