From Molecule to Aggregate: Designing AIE Nanocrystals for Low‐Power Backward Third‐Harmonic Generation Angiography

Advanced Materials, EarlyView.
An organic BTHG agent called OTBP with prominent crystallinity is developed. The resonant absorption at 433 nm and prominent crystallinity of OTBP enhance its BTHG efficiency when excited by a 1300 nm femtosecond laser. Tuning the size of OTBP nanocrystals based on Mie scattering theory successfully enables them to achieve high‐contrast muti‐organ ...

Pseudo Equality Algebras -- Revision [PDF]

arXiv, 2014
Recently Jenei introduced a new structure called equality algebras which is inspired by ideas of BCK-algebras with meet. These algebras were generalized by Jenei and K\'or\'odi to pseudo equality algebras which are aimed to find a connection with pseudo BCK-algebras with meet. We show that every pseudo equality algebra is an equality algebra. Therefore,

Interaction of Oligonucleotides with Gold Nanoparticles: Factors Beyond Electrostatic and Van‐Der Waals Forces

Advanced Materials Interfaces, EarlyView.
The formation of stable clusters of gold nanoparticles with oligonucleotides at different solution conditions is explored. DNA base homogeneity and strand directionality influence the binding with gold nanoparticles leading to interesting clustering behavior that can be relevant for SERS applications.

Statistical Eye Diagrams for High-Speed Interconnects of Packages: A Review

IEEE Access
An eye diagram, a critical metric in signal integrity analysis for high-speed interconnects such as packages, interposer, and printed circuit boards (PCBs), is generated by superposition of the received waveform.

Equality of Proofs for Linear Equality [PDF]

arXiv, 2006
This paper is about equality of proofs in which a binary predicate formalizing properties of equality occurs, besides conjunction and the constant true proposition. The properties of equality in question are those of a preordering relation, those of an equivalence relation, and other properties appropriate for an equality relation in linear logic.

Connecting Droplet Adhesion with Sperm Kinematics: A New Paradigm in Sperm Quality Monitoring

Advanced Materials Interfaces, EarlyView.
This study demonstrates direct experimental evidence to establish a nonintuitive connection between the motion characteristics of self‐propelled sperm cells and their surface interaction. Simultaneous motion visualization and cantilever‐deflection‐based adhesion characterization reveal that sperm‐cell droplets with higher motility exhibit lower surface

On the Complexity of Equivalence of Specifications of Infinite Objects [PDF]

arXiv, 2012
We study the complexity of deciding the equality of infinite objects specified by systems of equations, and of infinite objects specified by lambda-terms. For equational specifications there are several natural notions of equality: equality in all models, equality of the sets of solutions, and equality of normal forms for productive specifications. For

How to Achieve High Spatial Resolution in Organic Optobioelectronic Devices?

Advanced Materials Interfaces, EarlyView.
This study explores how the optoelectronic properties of organic semiconductors impact on the resolution of light‐activated bioelectronic interfaces. Using photovoltage and photocurrent microscopy techniques, the authors show that H2PC/PTCDI heterojunctions enable a resolution down to 6.5 µm due to low carrier mobility along the heterojunction.

Dynamic Microfluidic Synthesis of Zinc Oxide Nanowires: Impact of Channel Architecture on Growth Homogeneity and Uniformity

Advanced Materials Interfaces, EarlyView.
In situ synthesis of nanomaterials within microfluidic reactors in dynamic mode boosts the growth rate. Notably, microfluidic reactors with optimized tree‐branched microchannel networks enable outstanding homogeneity of 99% and excellent nanowires uniformity.

Evaporation‐Enhanced Redox Cycling for Rapid Detection of Attomolar SARS‐CoV‐2 Virions Using Nanolithography‐Free Electrochemical Devices

Advanced Materials Technologies, EarlyView.
This study presents microfabricated electrochemical sensors for detecting ultralow viral particles counts through evaporation‐enhanced redox cycling (E2RC). To achieve sub‐micrometer gap in interdigitated microelectrodes, a scalable, nanolithography‐free fabrication method is developed.
