Pillar-Layered Metal–Organic Frameworks Based on a Hexaprismane [Co6(μ3-OH)6] Cluster: Structural Modulation and Catalytic Performance in Aerobic Oxidation Reaction
Embedding a functional metal-oxo cluster within the matrix of metal–organic frameworks (MOFs) is a feasible approach for the development of advanced porous materials. Herein, three isoreticular pillar-layered MOFs (Co 6 -MOF-1–3) based on a unique [Co 6 (μ 3 –OH) 6 ] cluster were designed, synthesized, and structurall…
Self‐assembly synthesis of SnNb 2 O 6 /amino‐functionalized graphene nanocomposite as high‐rate anode materials for sodium‐ion batteries
Abstract A two‐dimensional (2D) SnNb 2 O 6 /amino‐functionalized graphene (En‐RGO) nanocomposite with a representative 2D–2D architecture has been constructed by an easy self‐assembly approach and firstly investigated as anode materials for secondary sodium‐ion batteries. The SnNb 2 O 6 nanosheets are evenly anchored…
Designing environment‐friendly chromium‐free Spinel‐Periclase‐Zirconia refractories for Ruhrstahl Heraeus degasser
Abstract Ruhrstahl Heraeus (RH) degassers are globally used to manufacture vacuum‐treated steel for automotive and railroad applications. The state‐of‐the‐art environment‐friendly chromium‐free alternatives for direct‐bonded magnesia‐chrome refractories used in RH degassers are expensive, and the scientific literature…
Enhancing myocardial repair with CardioClusters
Abstract Cellular therapy to treat heart failure is an ongoing focus of intense research, but progress toward structural and functional recovery remains modest. Engineered augmentation of established cellular effectors overcomes impediments to enhance reparative activity. Such ‘next generation’ implementation includes…
Far-Field Subwavelength Acoustic Imaging by Deep Learning
Seeing and recognizing an object whose size is much smaller than the illumination wavelength is a challenging task for an observer placed in the far field, due to the diffraction limit. Recent advances in near- and far-field microscopy have offered several ways to overcome this limitation; however, they often use inva…
Theory of strain-induced magnetic order and splitting of Tc and TTRSB in Sr2RuO4
The internal structure of the superconducting state in ${\mathrm{Sr}}_{2}\mathrm{Ru}{\mathrm{O}}_{4}$ remains elusive at present, and exhibits evidence for time-reversal symmetry breaking. Recent muon spin relaxation measurements under uniaxial strain have revealed an increasing splitting between the superconducting c…
A Practical Review of NMR Lineshapes for Spin-1/2 and Quadrupolar Nuclei in Disordered Materials
NMR is a powerful spectroscopic method that can provide information on the structural disorder in solids, complementing scattering and diffraction techniques. The structural disorder in solids can generate a dispersion of local magnetic and electric fields, resulting in a distribution of isotropic chemical shift δiso…
Flexible Ecoflex®/Graphene Nanoplatelet Foams for Highly Sensitive Low-Pressure Sensors
The high demand for multifunctional devices for smart clothing applications, human motion detection, soft robotics, and artificial electronic skins has encouraged researchers to develop new high-performance flexible sensors. In this work, we fabricated and tested new 3D squeezable Ecoflex® open cell foams loaded with…
A fully open-source framework for deep learning protein real-valued distances
As deep learning algorithms drive the progress in protein structure prediction, a lot remains to be studied at this merging superhighway of deep learning and protein structure prediction. Recent findings show that inter-residue distance prediction, a more granular version of the well-known contact prediction problem,…
Recent Advances on Purification of Lactic Acid
With increasing interest in developing biodegradable polymers to replace fossil-based products globally, lactic acid (LA) has been paid extensive attention due to the high environment-compatibility of its downstream products. The mainstream efforts have been put in developing energy-efficient conversion technologies t…
Cu/CuO Composite Track-Etched Membranes for Catalytic Decomposition of Nitrophenols and Removal of As(III)
One of the promising applications of nanomaterials is to use them as catalysts and sorbents to remove toxic pollutants such as nitroaromatic compounds and heavy metal ions for environmental protection. This work reports the synthesis of Cu/CuO-deposited composite track-etched membranes through low-temperature annealin…
How hair deforms steel
Steels for sharp edges or tools typically have martensitic microstructures, high carbide contents, and various coatings to exhibit high hardness and wear resistance. Yet they become practically unusable upon cutting much softer materials such as human hair, cheese, or potatoes. Despite this being an everyday observati…
Bication-Mediated Quasi-2D Halide Perovskites for High-Performance Flexible Photodetectors: From Ruddlesden–Popper Type to Dion–Jacobson Type
Quasi-2D halide perovskites, especially the Ruddlesden–Popper perovskites (RPPs), have attracted great attention because of their promising properties for optoelectronics; however, there are still serious drawbacks, such as inefficient charge transport, poor stability, and unsatisfactory mechanical flexibility, restri…
