Self‐Assembly Engineering of Fullerene‐Like Polyhedra: V60, V66, V72 From {MV5} Pentagonal Second Building Block

Advanced Science, EarlyView.
A precise self‐assembly of fullerene‐like V60‐MOP constructed from the first discovered polyoxovanadates five‐membered ring V5 units is discovered. In situ modifications are successfully used to insert {MO5} (M = V/Mo) in the center of the V5 ring, resulting in three other isomorphic spherical cages V66‐MOP, V72‐MOP, and V60Mo12‐MOP.

Congruent and Oriented Crystallization of Mixed Sn–Pb Perovskite From the Nano‐ to Centimeter Scale

Advanced Science, EarlyView.
A Lewis‐base ligand trimethylthiourea preferentially coordinates to Sn2+ over Pb2+ and regulates the crystallization kinetics of FASn0.5Pb0.5SnI3. The resulting films consist of nearly stoichiometric unit cells and micrometer‐sized crystal grains exposing their (100) face.

Antagonist Targeting the Species‐Specific Fatty Acid Dehydrogenase/Isomerase FabX for Anti‐H. pylori Infection

Advanced Science, EarlyView.
This study demonstrates that the atypical dehydrogenase/isomerase FabX in Type‐II fatty acid biosynthesis pathway is essential for H. pylori infection by retaining unsaturated fatty acid synthesis and producing superoxide (ROS). A small molecule FBX‐1991 that specifically targets FabX to inhibit H.

Tetrahedral Nitrogen Atoms Arrangement in A‐Site Cations: A New Approach for Regulating Sensitivity and Energy of Perovskite Energetic Materials

Advanced Science, EarlyView.
The urotropine is selected as the A‐site cation in PEMs, and four urotropine‐based PEMs ([C6H14N4][M(ClO4)3]) are successfully prepared. Compared with the cubic PEMs, the crystal structure of the urotropine‐based PEMs has an expansion along the c‐axis.

Two source emission behaviour of alpha fragments of projectile having energy around 1 GeV per nucleon [PDF]

arXiv, 2010
The emission of projectile fragments alpha has been studied in ^{84}Kr interactions with nuclei of the nuclear emulsion detector composition at relativistic energy below 2 GeV per nucleon. The angular distribution of projectile fragments alpha in terms of transverse momentum could not be explained by a straight and clean-cut collision geometry ...

Customised fragment libraries for ab initio protein structure prediction using a structural alphabet [PDF]

arXiv, 2020
Motivation: Computational protein structure prediction has taken over the structural community in past few decades, mostly focusing on the development of Template-Free modelling (TFM) or ab initio modelling protocols. Fragment-based assembly (FBA), falls under this category and is by far the most popular approach to solve the spatial arrangements of ...

Upscaling Perovskite Photovoltaics: from 156 cm2 Modules to 0.73 M2 Panels

Advanced Science, EarlyView.
From lab to sunlight: perovskite photovoltaics are scaled from 156 cm² large area modules to 0.73 m² panels. With 17.68% efficiency at module level and a stron 12% PCE in outdoor conditions, this advance represents a significant step toward real‐world deployment, paving the way from innovation to practical application.

N-linked Fc glycosylation is not required for IgG-B-cell receptor function in a GC-derived B-cell line

Nature Communications
IgG secreted by B cells carry asparagine N(297)-linked glycans in the fragment crystallizable (Fc) region. Changes in Fc glycosylation are related to health or disease and are functionally relevant, as IgG without Fc glycans cannot bind to Fcɣ receptors ...

Local Immune Activation and Age Impact on Humoral Immunity in Mice, with a Focus on IgG Sialylation

Vaccines
Age alters the host’s susceptibility to immune induction. Humoral immunity with circulating antibodies, particularly immunoglobulin G (IgG), plays an essential role in immune response.

Highly Oriented SiC@SiO2 Ceramic Fiber Aerogels with Good Anisotropy of the Thermal Conductivity and High‐Temperature Resistance

Advanced Science, EarlyView.
The anisotropic‐structure SiC@SiO2 ceramic fiber aerogels feature aligned layers stacking layer‐by‐layer with the same direction and highly oriented 1D fibers inside each layer, resulting in an anisotropy factor as high as 5.08. Not only does it have 60% high recoverable deformation, but it also shows great promise for thermal protection in extreme ...
