Ideal Molecular Sieving with a Dense MOF for Helium Upgrading with Highly Diffusion Selective Mixed Matrix Membranes

Advanced Functional Materials, EarlyView.
The separation of Helium gas from natural gas is challenging but highly important. MIL‐116(Ga), a “non‐porous” metal–organic framework is used as a molecular sieve to separate He from CH4. Druse‐like MIL‐116(Ga) particles are integrated into polysulfone mixed matrix membranes.

Study on particulate matter emissions from traffic by cellular automaton model with slow-to-start effect [PDF]

arXiv, 2020
Based on the empirical particulate emission model, we studied Particulate Matter (PM) emission of some typical cellular automata VDR model and TT model with slow-to-start rules under periodic condition and open boundary condition. By simulations, it is found that the emission of the slow-to-start rule model reaches the maximum emission at metastable ...

Supercritical Fluid‐Processed Multifunctional Hybrid Decellularized Extracellular Matrix with Chitosan Hydrogel for Improving Photoaged Dermis Microenvironment

Advanced Healthcare Materials, EarlyView.
These findings advance tissue repair by offering a multifunctional filler that improves large‐scale volume retention, elasticity, and support for vascularized tissue growth. The decellularized extracellular matrix (dECM)‐based material provides low injection force and minimizes swelling, ensuring sustained volume. Combining CMC with supercritical fluid‐

Particules inconnues. I

Bulletin de la Classe des sciences, 1960
The possible existence of undiscovered elementary particles is discussed. The electric charge Q and the « neutrinonic charge » R, introduced in a preceding paper (x), are given for two such particles, which are baryons : Q = 1, R = 0 and Q = -1, R = -2 ; for the newly discovered D-meson, they are Q = 1, R = 1.

Universal Hydrogel Carrier Enhances Bone Graft Success: Preclinical and Clinical Evaluation

Advanced Healthcare Materials, EarlyView.
TX hydrogel improves the delivery of different types of particulate bone grafts, maintaining them at the implantation sites, and resulting in favorable bone regenerative outcomes. Abstract Orthopedic, maxillofacial, and complex dentoalveolar bone grafting procedures that require donor‐site bone harvesting can be associated with post‐surgical ...
