Revealing the structure of land plant photosystem II: the journey from negative‐stain EM to cryo‐EM

open access: yesFEBS Letters, EarlyView.
Advances in cryo‐EM have revealed the detailed structure of Photosystem II, a key protein complex driving photosynthesis. This review traces the journey from early low‐resolution images to high‐resolution models, highlighting how these discoveries deepen our understanding of light harvesting and energy conversion in plants.

Investigation of Methacryloyl‐Modified Gelatin‐Based Hydrogels for Inkjet‐Printed Biosensors and Their Adherence to Polyethylene Terephthalate and Oriented Polypropylene Substrates

open access: yesEngineering in Life Sciences
The COVID‐19 pandemic has highlighted the need for rapid, simple, and cost‐effective point‐of‐care testing (POCT) methods for pathogen detection. Hydrogel‐based biosensing has emerged as an increasingly popular approach, offering advantages such as ...

W/Si Multilayer Mirrors for Soft X-Ray Wavelengths < 2.4 nm

open access: yesSurfaces
W/Si multilayer mirrors are a promising candidate for soft X-ray applications at wavelengths below 2.4 nm. However, their optical performance is strongly affected by interface roughness and interlayer mixing, which limits reflectivity.

Mapping the evolution of mitochondrial complex I through structural variation

open access: yesFEBS Letters, EarlyView.
Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)

On a new conformal functional for simplicial surfaces

open access: yes, 2015
We introduce a smooth quadratic conformal functional and its weighted version $$W_2=\sum_e \beta^2(e)\quad W_{2,w}=\sum_e (n_i+n_j)\beta^2(e),$$ where $\beta(e)$ is the extrinsic intersection angle of the circumcircles of the triangles of the mesh ...

Monogenic functions on surfaces.

open access: yesJournal für die reine und angewandte Mathematik (Crelles Journal), 1985
In this paper we introduce two sequences \((\Gamma_ k)_{k\to {\mathbb{N}}}\) and (\({\tilde \Gamma}{}_ k)_{k\in {\mathbb{N}}}\) of generalized Cauchy- Riemann operators on an m-dimensional surface \(\Sigma\) of \({\mathbb{R}}^{m+1}\). The first operators \(\Gamma_ 0\) and \({\tilde \Gamma}{}_ 0\) may be considered as generalizations to surfaces of the ...

Organoids in pediatric cancer research

open access: yesFEBS Letters, EarlyView.
Organoid technology has revolutionized cancer research, yet its application in pediatric oncology remains limited. Recent advances have enabled the development of pediatric tumor organoids, offering new insights into disease biology, treatment response, and interactions with the tumor microenvironment.

Effect of reinforcement ratio on contact angle in hydrophobic/superhydrophobic AA5754/SiCp composite materials [PDF]

open access: yesProceedings of the Estonian Academy of Sciences
Functional surfaces are defined as smart surfaces with properties different from the material’s own properties. These surfaces increase energy efficiency in various applications, reduce costs by extending the lifetime of materials, and contribute to ...

Electrical properties of zinc nitride and zinc tin nitride semiconductor thin films toward photovoltaic applications

open access: yesHigh Temperature Materials and Processes, 2022
Zn3N2 (ZN) and ZnSnN2 (ZTN) are a promising class of nitride semiconductors for photovoltaic and light-emitting-diode applications due to their particular electrical and optical properties, elemental abundance and non-toxicity.
