Engineering Strategies for Stable and Long‐Life Alkaline Zinc‐Based Flow Batteries

open access: yesAdvanced Functional Materials, EarlyView.
Alkaline zinc‐based flow batteries face persistent challenges from unstable zinc deposition, including dendrite growth, passivation, corrosion, and hydrogen evolution, which severely limit cycling stability. Current research addresses these issues through coordinated electrode structuring, electrolyte regulation, and membrane design to control zinc ...

Passage kinetics of concentrates in dairy cows measured with carbon stable isotopes

open access: yesAnimal, 2013
Fractional passage rates form a fundamental element within modern feed evaluation systems for ruminants, but knowledge on feed-specific fractional passage is largely lacking. Commonly applied tracer techniques based on externally applied markers, such as

Shape‐Controlled Guanine Self‐Assemblies for Stable and Fast‐Ion Solid–Electrolyte Interphases in Sustainable Li Metal Batteries

open access: yesAdvanced Functional Materials, EarlyView.
The shape of guanine self‐assemblies is tuned by introducing alkyl (G8), fluoroalkyl (G8f), and oligoether (G8g) side chains into the G moiety. The scanning tunneling microscopy results and calculations show that the presence and type of the side chain strongly affect the G self‐assembly network.

Single‐ and Dual‐Atom Configurations in Atomically Dispersed Catalysts for Lithium–Sulfur Batteries

open access: yesAdvanced Functional Materials, EarlyView.
Single‐atom and dual‐atom‐based atomically dispersed catalysts (ADCs) effectively address the shuttle effect and sluggish redox kinetics in Li–S batteries. With nearly 100% atomic utilization and tunable coordination environments, ADCs enhance LiPSs adsorption, lower conversion barriers, and accelerate sulfur redox reactions.

Impaired synthesis of DHA in patients with X-linked retinitis pigmentosa

open access: yesJournal of Lipid Research, 2001
Many patients with X-linked retinitis pigmentosa (XLRP) have lower than normal blood levels of the long-chain polyunsaturated ω3 fatty acid docosahexaenoic acid (DHA; 22:6 ω3).

Hyperpolarized Nanodiamond with Long Spin Relaxation Times

open access: yes, 2015
The use of hyperpolarized agents in magnetic resonance (MR), such as 13C-labeled compounds, enables powerful new imaging and detection modalities that stem from a 10,000-fold boost in signal.

The Terminal Domains of Collagen‐Like Silk Direct Molecular Interactions and Liquid–Liquid Phase Separation‐Mediated Material Assembly

open access: yesAdvanced Functional Materials, EarlyView.
Terminal domains of recombinant collagen‐like silk regulate hierarchical self‐assembly across molecular and material scales. We show that terminal domains of collagen‐like silk enhance triple‐helix stability and drive liquid–liquid phase separation, enabling reversible formation of fibers and self‐healing films.

Investigation of Halogen Substitution Effects in π‐Conjugated Organic Ligands of Chiral Hybrid Perovskites on Their Chiroptical Activity

open access: yesAdvanced Functional Materials, EarlyView.
The role of novel thiophene‐based ligands with halogen substitutions in enhancing the chiroptical and optoelectronic properties of 2D chiral HOIPs has been investigated. By tailoring ligand design, enhanced CD and CPL properties are achieved, with improved CPL discrimination in photodetectors.
