A Tracer Diffusion Study of Diverse Photo‐Ionic Phenomena in Strontium Titanate

Advanced Functional Materials, Volume 36, Issue 22, 16 March 2026.
Two strong interfacial photo‐ionic effects are demonstrated for the model system SrTiO3 through the application of isotope exchange experiments: UV illumination is found to enhance the oxygen surface exchange coefficient by several orders of magnitude and to depress the surface space‐charge potential substantially.

Design and Analysis of Time-Invariant SC-LDPC Convolutional Codes With Small Constraint Length

, 2017
In this paper, we deal with time-invariant spatially coupled low-density parity-check convolutional codes (SC-LDPC-CCs). Classic design approaches usually start from quasi-cyclic low-density parity-check (QC-LDPC) block codes and exploit suitable ...

Probing Cellular Activity Via Charge‐Sensitive Quantum Nanoprobes

Advanced Materials, Volume 38, Issue 14, 6 March 2026.
A new quantum sensing modality detects shifts in zero‐field splitting caused by charge rearrangement with diamond nanocrystals in response to cellular activity. These electric‐field‐driven effects provide an alternative to temperature‐based interpretations, enabling real‐time, single‐cell readout of inflammation.

Explicit construction of girth-eight QC-LDPC codes and its application in CRT method

Tongxin xuebao, 2012
For arbitrary code lengths of the form PL(P≥3L²/4+L-1),a new family of (4,L)-regular quasi-cyclic (QC) low-density parity-check (LDPC) codes was proposed explicitly with girth ight.Employing the new code as a component code in the ...

Crystal Engineering of Reticular Materials for Gas‐ and Liquid‐Phase Hydrocarbon Separation

Advanced Materials, Volume 38, Issue 16, 17 March 2026.
Crystal engineering enables systematic study of structure/function relationships as exemplified by pore engineering of reticular sorbents, including porous coordination networks and covalent organic frameworks. This review assesses such studies applied across the full scope of industrially relevant hydrocarbon separations to provide insight into how ...

Fatigue crack growth characteristics of Fe and Ni under cyclic loading using a quasi-continuum method

Beilstein Journal of Nanotechnology, 2018
A quasi-continuum (QC) method based on the embedded atom method (EAM) potential was employed to investigate the fatigue crack growth and expansion characteristics of single-crystal Fe and Ni under cyclic loading modes I and II.

Unlocking the THz Emission Potential of Sputtered Germanium Thin Films Through Structural and Optoelectronic Properties Optimization

Advanced Optical Materials, Volume 14, Issue 10, 13 March 2026.
An optimized RF‐sputtering process is developed for the deposition of n‐doped germanium thin films exhibiting strongly enhanced THz emission under fs‐laser excitation. By tuning deposition temperature and thickness, highly (111)‐oriented films with an effective bandgap of ∼0.77 eV and improved optoelectronic properties are achieved, leading to a ∼35 ...

On the Girth of Tanner (3, 13) Quasi-Cyclic LDPC Codes

IEEE Access, 2019
Girth is an important structural property of low-density parity-check (LDPC) codes. Motivated by the works on the girth of Tanner (3, 5), (3, 7), (3, 11), and (5, 7) quasi-cyclic (QC) LDPC codes, we, in this paper, study the girth of Tanner (3, 13) QC ...
