Red Blood Cell Membrane Mechanics Using Discrete Exterior Calculus (DEC) and Optimization. [PDF]

Int J Numer Method Biomed Eng
We present a novel DEC approach for calculating RBC shapes applicable to other cell types and membrane problems. We derive an energy minimization equation that can be solved semi‐implicitly, and a Lie derivative method to control node spacing. This novel work should aid computational modeling in many biological situations.

Differently N‐Capped Analogues of Fmoc‐FF

Chemistry – A European Journal, Volume 29, Issue 28, May 16, 2023., 2023
Fmoc‐FF analogues were collected and analyzed in their morphological, mechanical, and functional features, highlighting the effects caused by the Fmoc‐ modification. Abstract Short and ultra‐short peptides have been recently envisioned as excellent building blocks for the formulation of hydrogels with appealing properties.

Self-assembly of cubic colloidal particles at fluid-fluid interfaces by hexapolar capillary interactions [PDF]

, 2018
Colloidal particles adsorbed at fluid–fluid interfaces can self-assemble, thanks to capillary interactions, into 2D ordered structures. Recently, it has been predicted by theoretical and numerical calculations [G. Soligno et al., Phys. Rev.

Direct Methanation and Storage Concepts for the Flexibilization of Biogas Plants

Chemical Engineering &Technology, Volume 46, Issue 3, Page 579-586, March 2023., 2023
Enrichment of the methane fraction in a biogas mixture is a possibility, though challenging, to optimize the existing biogas plants by using excess power. The methanation process and the consequent heat release are studied in a laboratory biogas plant with an innovative heat pipe injector system for cooling the enriched biogas and remixing the biomass ...

Net‐mineralization of organic matter and greenhouse gas emissions from Quebracho tannin‐enriched manure applied to acidic and alkaline soils

Journal of Plant Nutrition and Soil Science, Volume 184, Issue 5, Page 530-542, October 2021., 2021
Abstract Background Mitigation strategies to reduce greenhouse gas emissions, ammonia volatilization, and nitrate leaching from agriculture are important for the management of environmental pollution and climate change. Tannins, which are water‐soluble polyphenolic compounds, were found to reduce emissions in animal husbandry systems when supplemented ...

Unconventional quantum Hall effect and Berry’s phase 2pi in bilayer graphene. [PDF]

, 2006
There are known two distinct types of the integer quantum Hall effect. One is the conventional quantum Hall effect, characteristic of two-dimensional semiconductor systems, and the other is its relativistic counterpart recently observed in graphene ...

Climate change drives habitat contraction of a nocturnal arboreal marsupial at its physiological limits

Ecosphere, Volume 11, Issue 10, October 2020., 2020
Abstract Increasing impacts of climatic change and anthropogenic disturbances on natural ecosystems are leading to population declines or extinctions of many species worldwide. In Australia, recent climatic change has caused population declines in some native fauna.

Exciton-polariton condensates near the Dirac point in a triangular lattice [PDF]

, 2013
Dirac particles, massless relativistic entities, obey linear energy dispersions and hold important implications in particle physics. The recent discovery of Dirac fermions in condensed matter systems including graphene and topological insulators has ...

Tuning edge state localization in graphene nanoribbons by in-plane bending

, 2015
The electronic properties of graphene are influenced by both geometric confinement and strain. We study the electronic structure of in-plane bent graphene nanoribbons, systems where confinement and strain are combined.
