Microbial Contribution to Soiling and Its Impact on Photovoltaic Module Soiling in Arid Zones of the Atacama Desert

open access: yesAdvanced Sustainable Systems, EarlyView.
Microorganisms colonizing photovoltaic surfaces in the Atacama desert form biofilms that enhance particle adhesion and reduce energy yield. This study identifies UV‐resistant bacteria and carotenoid‐producing strains that interfere with PV performance.

Biocatalytic Regioselective C‐Formylation of Resorcinol Derivatives

open access: yesAngewandte Chemie, EarlyView.
An acyltransferase from Chromobacterium sphagni (CsATase) was identified that catalyzes the regioselective formylation of resorcinol substrates. The formylation of substituted resorcinol derivatives yielded mono‐formylated products with up to 99% conversion and up to 74% isolated yield.

Modeling Pine and Birch Whole Tree Drying in Bunches in the Cutting Area

open access: yesCroatian Journal of Forest Engineering, 2017
Natural drying is practiced to improve the quality of fuel wood. The purpose of this study is to obtain the mathematical model of natural drying of whole trees stacked in bunches in the cutting area. To do this, an experimental study of natural drying of

Towards a semantic typology of specific determiners [PDF]

open access: yes, 2017
This paper investigates properties of a class of determiners which can be loosely la- belled specific in that their distribution falls in between maximally-quantifying definite determiners and indefinites which only contribute existential quantification.

Dynamiques diglossiques en Mari El (fédération de Russie)

open access: yesÉtudes finno-ougriennes, 2021
The Mari language, a language from the Finno-Volgaic group, is besides Russian the official language of the Republic of Mari-El, eight hundred kilometres East from Moscow. In this article, I attempt firstly to distinguish the Mari as an ethnic group, on the one hand, and the Mari speaking people; on the other hand the Republic of Mari El and the Mari ...

Bacteriophage‐Mimetic DNA Origami Needle for Targeted Membrane Penetration and Cytosolic Cargo Delivery

open access: yesAdvanced Science, EarlyView.
We designed a synthetic DNA origami needle‐like structure inspired by bacteriophages for targeted drug delivery. Functionalized with trastuzumab antibodies, cholesterol, and dyes, it selectively targets SKBR3 cancer cells. A glutathione‐triggered dye payload enables controlled release, and delivery is verified using confocal microscopy and live cell ...

Inelastic neutron scattering studies of the quantum frustrated magnet clinoatacamite, $\gamma$-Cu2(OD)3Cl, a proposed valence bond solid (VBS)

open access: yes, 2009
The frustrated magnet clinoatacamite, $\gamma$-Cu$_2$(OH)$_3$Cl, is attracting a lot of interest after suggestions that at low temperature it forms an exotic quantum state termed a Valence Bond Solid (VBS) made from dimerised Cu$^{2+}$ ($S=1/2$) spins ...
