Stripe and bubble ratchets on asymmetric substrates

open access: yesPhysical Review Research
We show that various nonmonotonic ratchet effects can arise when mesophase pattern-forming systems, which exhibit anisotropic crystal, stripe, and bubble regimes, are coupled to one-dimensional asymmetric substrates under ac driving.

H-Bonding-Induced Repulsion Between Small Groups Toward a Highly Puckered Benzene. [PDF]

open access: yesAdv Sci (Weinh)
A benzene derivative bearing methylamino and nitro substituents adopts a boat‐shaped ring conformation. Comparison with four related compounds supports a role for intramolecular hydrogen bonding in constraining substituent orientations and promoting local steric crowding associated with ring puckering.

A class of attraction/repulsion functions for stable swarm aggregations

open access: yes, 2002
In this article, for an M-member "individual-based" continuous time swarm model in an n-dimensional space, we extend the results in [1] by specifying a general class of attraction/repulsion functions that can be used to achieve swarm aggregation.

Charge‐Reversed Lipid Nanoparticles Enable Encapsulation of Pt2L4 Nanocages for In vivo Anti‐Cancer Treatment

open access: yesAdvanced Materials, EarlyView.
Charge‐reversed lipid nanoparticles (revLNPs) enable efficient encapsulation and delivery of cationic Pt2L4 nanocages. Encapsulation preserves potent anticancer activity while improving circulation, reducing vascular leakage, and promoting favorable biodistribution in vivo.

Biomass DNA: An Emerging Building Block for Advanced Materials

open access: yesAdvanced Materials, EarlyView.
Biomass DNA is rapidly emerging from its traditional role as a genetic blueprint to serve as a versatile abundant, highly programmable polymeric building block. This review highlights the transformation of macroscopic bulk biomass DNA into next generation of functional materials, spanning from dynamic hydrogels, sustainable bioplastics, and high ...

Ultra‐White Elastomeric Coatings for Daytime Radiative Cooling

open access: yesAdvanced Materials Technologies, EarlyView.
Passive daytime radiative cooling meets elasticity in a new class of ultra‐white silicone coatings. Combining high solar reflectance with strong sky‐window emission, they hold surfaces below ambient temperature under full sunlight while remaining flexible and stretchable. This combination of cooling performance and mechanical flexibility enables energy‐

From Identity to Uniqueness: The Emergence of Increasingly Higher Levels of Hierarchy in the Process of the Matter Evolution

open access: yesEntropy, 2018
This article focuses on several factors of complification, which worked during the evolution of our Universe. During the early stages of such evolution up to the Recombination Era, it was laws of quantum mechanics; during the Dark Ages it was gravitation;

Segmentation with Pairwise Attraction and Repulsion

open access: yes, 2008
We propose a method of image segmentation by integrating pairwise attraction and directional repulsion derived from local grouping and figure-ground cues.

Direct Measurement of Interhelical DNA Repulsion and Attraction by Quantitative Cross-Linking

open access: yes, 2022
To better understand the forces that mediate nucleic acid compaction in biology, we developed the disulfide cross-linking approach xHEED (X-linking of Helices to measure Electrostatic Effects at Distance) to measure the distance-dependent encounter ...
