Crystallization Dynamics of Hybrid Perovskite Mediated by a Biopolymer: From Precursor Solution to Thin Film

open access: yesAdvanced Materials Interfaces, EarlyView.
In order to better understand the complex crystallization dynamics of starch‐assisted metal halide perovskites (MHPs), the properties of colloidal precursor suspensions and the thermodynamic evolution of the crystallization reaction are investigated by a comprehensive set of characterization techniques, from solutions to films.

Spatiotemporal Super‐Resolution Imaging of Lipid Metabolism Dynamics in Physiological/Pathological Conditions

open access: yesAngewandte Chemie, EarlyView.
A novel polarity‐sensitive fluorescent probe was developed for the selective targeting of lipid droplets, enabling precise visualization and quantification of lipid metabolism disorders using an integrated STED‐FLIM platform. This probe allows accurate monitoring of lipid metabolism in cellular and pathological contexts, such as atherosclerosis ...

Shape‐Selective Molecular Separations Enabled by Rigid and Interconnected Confinements Engineered in Conjugated Microporous Polymer Membranes

open access: yesAdvanced Science, EarlyView.
Conjugated microporous polymer membranes with narrowly distributed network pores are prepared by diffusion‐modulated electropolymerization. This approach precisely controls the monomer diffusion and coupling processes, regulating the crosslinking degree to prevent broad aggregate pores and microporous defects.

Revealing the Nature of Non‐Covalent Interactions in Ionic Liquids by Combined Pulse EPR and 19F NMR Spectroscopy

open access: yesAngewandte Chemie, EarlyView.
Ionic liquids have been proposed as alternatives to molecular solvents. Here, spin probes and spin‐labelled ILs are studied by pulse electron paramagnetic resonance, paramagnetic relaxation enhancement NMR, molecular dynamics, and density functional theory, revealing the IL interaction sphere. The results challenge previous interpretations of nitroxide‐

Dual‐Locking the SARS‐CoV‐2 Spike Trimer: An Amphipathic Molecular “Bolt” Stabilizes Conserved Druggable Interfaces for Coronavirus Inhibition

open access: yesAdvanced Science, EarlyView.
A new amphipathic molecule, S416 is discovered, that locks the SARS‐CoV‐2 spike protein in its closed state, blocking viral entry. S416 acts as a molecular bolt, binding six sites: three between adjacent RBDs and three connecting NTDs to RBDs. This dual‐locking mechanism stiffens the spike structure and reduces its flexibility.

Simultaneous observations of haemolymph flow and ventilation in marine spider crabs at different temperatures: a flow weighted MRI study [PDF]

open access: yes, 2001
In vivo magnetic resonance imaging (MRI) and angiography were applied to the marine spider crab Maja squinado for a study of temperature effects and thermal tolerance.

Natural Toolbox–Chemical Engineering Aspect and High‐Value Applications of Janus Cellulose Nanomaterials

open access: yesAdvanced Science, EarlyView.
The Tai Ji symbol from China represents the co‐existence of two opposite substances, similar to quantum entanglement. The term Janus comes from ancient Roman religion and mythology. Janus, the god of beginnings, transitions, etc., has two faces, symbolizing duality. Janus cellulose nanomaterials show structural duality.

Effects of Chronic Cd Exposure via the Diet or Water on Internal Organ-Specific Distribution and Subsequent Gill Cd Uptake Kinetics in Juvenile Rainbow Trout (\u3cem\u3eOncorhynchus mykiss\u3c/em\u3e) [PDF]

open access: yes, 2001
New regulatory approaches to metal toxicity (e.g., biotic ligand model [BLM]) focus on gill metal binding and tissue specific accumulation of waterborne metals; the dietary route of exposure and dietary/waterborne interactions are not considered, nor are

Conodont biostratigraphy of the Crawford Group, Southern Uplands, Scotland [PDF]

open access: yes, 2002
Extensive new conodont collections from the Crawford Group, the oldest succession in the Southern Uplands of Scotland, support the previously documented biostratigraphical ages for the included formations.

Nanogenerator Neuromodulation to Enable Locomotion Rehabilitation for Spinal Cord Injury via Epidural Electrical Stimulation

open access: yesAdvanced Science, EarlyView.
A hybrid nanogenerator (H‐NG) has been developed to be applied in epidural electrical stimulation (EES). Compared with a commercial stimulus generator (SG), the H‐NG can elicit hindlimb locomotion in rats with much lower electrical parameters and much smaller individual differences.
