Ab Initio Study on 3D Anisotropic Ferroelectric Switching Mechanism and Coercive Field in HfO2 and ZrO2

Advanced Functional Materials, EarlyView.
This study uncovers a new switching mechanism in HfO2 and ZrO2, where the absence of a non‐polar layer along the a‐direction induces interaction between polar layers. Consequently, the switching barriers for growth are lower than those for nucleation in this direction, leading to a size‐dependent coercive field that matches experimental observations ...

Calcaneus and Traumatic Stress Fracture

Journal of Orthopaedic Case Reports
Introduction: Although uncommon, the calcaneus stress fracture is an important differential diagnosis of both traumatic and non-traumatic foot pain. The calcaneus is one of the tarsal bones that are prone to stress fractures, which usually occur as a ...

Conservative descent for semi-orthogonal decompositions

, 2019
Motivated by the local flavor of several well-known semi-orthogonal decompositions in algebraic geometry, we introduce a technique called conservative descent, which shows that it is enough to establish these decompositions locally. The decompositions we

Photoactivation of NV Centers in Diamond via Continuous Wave Laser Illumination of Shallow As‐Implanted Nitrogen

Advanced Functional Materials, EarlyView.
This study demonstrates an alternative method of creating charge‐stable negatively charged nitrogen vacancy (NV−) centers close to the diamond surface without high‐temperature annealing. By illuminating nitrogen‐implanted regions with a continuous‐wave 405 nm laser, NV− centers are induced, exhibiting electron spin coherence properties suitable for ...

Prospects of Electric Field Control in Perpendicular Magnetic Tunnel Junctions and Emerging 2D Spintronics for Ultralow Energy Memory and Logic Devices

Advanced Functional Materials, EarlyView.
Electric control of magnetic tunnel junctions offers a path to drastically reduce the energy requirements of the device. Electric field control of magnetization can be realized in a multitude of ways. These mechanisms can be integrated into existing spintronic devices to further reduce the operational energy.

Conservative Progress [PDF]

The Boston Medical and Surgical Journal, 1884
The advance of science is hindered not more by obstinacy than by fickleness. The skepticism which uses an honest crucible is a blessing; the skepticism which wields a club, and smashes old things indiscriminately because they are ancient, is a curse. Underneath its destructive malice is often a credulous and craven tenderness for anything which is new.

Laser‐Induced Graphene from Waste Almond Shells

Advanced Functional Materials, EarlyView.
Almond shells, an abundant agricultural by‐product, are repurposed to create a fully bioderived almond shell/chitosan composite (ASC) degradable in soil. ASC is converted into laser‐induced graphene (LIG) by laser scribing and proposed as a substrate for transient electronics.

Efficacy and safety of volar locking plate versus cast immobilization for distal radius fractures: a systematic review and meta-analysis of randomized controlled trials

Journal of Plastic Surgery and Hand Surgery
Volar locking plates (VLPs) are increasingly used for distal radius fractures (DRFs), yet their efficacy compared to cast immobilization remains debated.
