Introducing Pure Calcium Orthophosphate Gels and Aerogels

Advanced Functional Materials, EarlyView.
The synthesis of calcium phosphate‐based gels and aerogels is reported, which exhibit highly porous structures built up of networks of nanoparticles. In case of amorphous aerogels, this leads to yet unmatched specific BET surface areas, making these materials especially interesting for biomedical applications.

Chiral Nanohoops as an Efficient Spin Polarization System

Advanced Functional Materials, EarlyView.
Chiral conjugated nanohoops with a central dibenzopentalene unit exhibit 90% spin polarization at low voltage and high conductivity. These properties make them ideal components in molecular spintronics applications. Abstract A central challenge in molecular spintronics is to achieve a high spin polarization at low operating voltages and ambient ...

Rational Design of Printable Carbon Nanotube Transparent Conductive Films via Data‐Driven and Mechanistic Insights

Advanced Functional Materials, EarlyView.
A machine learning and simulation‐guided strategy is demonstrated for gentle, non‐sonication dispersion of carbon nanotubes, preserving structural integrity and performance. This approach enables transparent conductive films with low sheet resistance, high transmittance, and sub‐20 µm printability.

The effect of tube diameter on vertical two-phase flow regimes in small tubes [PDF]

, 2006
Flow boiling flow patterns in four circular tubes with internal diameters of 1.10, 2.01, 2.88 and 4.26 mm were investigated in the present project. The experiments were conducted in vertical upward two-phase flow using R134a as the working fluid.

Laser‐Microscribed Glass Enables Surface‐Microfluidics‐Facilitated, Affordable, Rapid Cancer Diagnosis

Advanced Functional Materials, EarlyView.
A transparent, laser‐microscribed glass platform enables cancer diagnosis within 1 h—much faster than histology, which takes days, and free from the chemical or contrast risks of MRI or CT scans. The antibody‐functionalized rough glass surface captures viable cancer cells directly from suspension, allowing instant optical readout and offering a rapid ...

Bioinspired Polypeptide Dendrimer‐Modified Thin‐Film Composite Membranes for Selective Lithium‐Magnesium Separation with DFT Insights

Advanced Functional Materials, EarlyView.
We fabricated a biomimetic dendrimer‐modified thin‐film nanocomposite membrane with a coordination‐assisted ion‐selective interface. pH‐responsive polypeptide sites preferentially bind Mg2+ and promote Li+ permeation, as predicted by density functional theory calculations of metal‐ligand interactions.
