Z boson events at the Large Hadron Collider can be selected with high purity and are sensitive to a diverse range of QCD phenomena. As a result, these events are often used to probe the nature of the strong force, improve Monte Carlo event generators, and search for deviations from standard model predictions. All previous measurements of Z boson production characterize the event properties using a small number of observables and present the results as differential cross sections in predetermined bins.

On the reactivity of complexes [Ni(NHC)] with CS.

Dalton Trans

January 2025

Institute for Inorganic Chemistry, Julius-Maximilians-Universität Würzburg, Am Hubland, 97074 Würzburg, Germany.

A study of the reaction of [Ni(NHC)] synthons with the heterocumulene CS is reported. Nickel complexes of η-(C-S) coordinated CS, [Ni(NHC)(η-CS)] (NHC = IiPr (1a), IiPr (1b)) were obtained from the reaction of CS with precursors of [Ni(NHC)] (NHC = IiPr, IiPr). The result of this reaction critically depends on the NHC employed, as [Ni(IMes)], the complex of the sterically more demanding -aryl substituted NHC IMes, led to formation of the dinuclear complex [{Ni(IMes)(μ-CS)}] (2d).

The reaction of the diborabenzene (DBB) nickel(0) pogo-stick complex [(η-DBB)Ni(CO)] () with a large excess of [Ni(CO)] yields the dark green, unstable dinickel(0) complex [(η-DBB)Ni(μ-CO)Ni(CO)] (), which loses one CO ligand to yield the purple, bimetallic Ni half-sandwich complex [(η-DBB)Ni(μ-CO)(η-CO)] (). The addition of the chromium aminoborylene complex [(OC)Cr{BN(TMS)}] (TMS = trimethylsilyl) to does not result in the expected borylene transfer but in the formation of the black Ni-Cr complex [(η-DBB)Ni(μ-CO)Cr(CO)] (), alongside the dimeric iminoborane [(TMS)BN(TMS)] (), which results from the rearrangement of the released BN(TMS) aminoborylene moiety. Furthermore, the oxidative addition of methyl triflate (MeOTf) to leaves the (η-DBB)Ni moiety intact and provides the ionic Ni half-sandwich complex [(η-DBB)NiMe(CO)]OTf (), while reaction with pentaphenylborole (PPB) yields the unique, dark-blue, unsymmetrical sandwich complex [(η-DBB)Ni(μ-CO)(η-PPB)] ().

Process-based models for range dynamics are urgently needed due to increasing intensity of human-induced biodiversity change. Despite a few existing models that focus on demographic processes, their use remains limited compared to the widespread application of correlative approaches. This slow adoption is largely due to the challenges in calibrating biological parameters and the high computational demands for large-scale applications.

The direct incorporation of borondipyrromethene (BODIPY) subunits into the structural backbone of covalent organic frameworks (COFs) gives facile access to porous photosensitizers but is still a challenging task. Here, we introduce β-ketoenamine-linked BDP-TFP-COF, which crystallizes in AA-stacking mode with hcb topology. A comprehensive characterization reveals high crystallinity and enhanced stability in a variety of solvents, excellent mesoporosity (SA=1042 m g), broad light absorption in the visible region, and red emission upon the exfoliation of few-layer COF nanosheets.

Diffusion Generative Models for Designing Efficient Singlet Fission Dimers.

J Phys Chem A

January 2025

Institute of Physical and Theoretical Chemistry, Julius-Maximilians-Universität Würzburg, Emil-Fischer-Str. 42, Würzburg 97074, Germany.

Diffusion generative models, a class of machine learning techniques, have shown remarkable promise in materials science and chemistry by enabling the precise generation of complex molecular structures. In this article, we propose a novel application of diffusion generative models for stabilizing reactive molecular structures identified through quantum mechanical screening. Specifically, we focus on the design challenge presented by singlet fission (SF), a phenomenon crucial for advancing solar cell efficiency beyond theoretical limits.

Ribozymes that catalyze site-specific RNA modification have recently gained increasing interest for their ability to mimic methyltransferase enzymes and for their application to install molecular tags. Recently, we reported SAMURI as a site-specific alkyltransferase ribozyme using S-adenosylmethionine (SAM) or a stabilized analog to transfer a methyl or propargyl group to N of an adenosine. Here, we report the crystal structures of SAMURI in the postcatalytic state.

High-energy nuclear collisions create a quark-gluon plasma, whose initial condition and subsequent expansion vary from event to event, impacting the distribution of the eventwise average transverse momentum [P([p_{T}])]. Disentangling the contributions from fluctuations in the nuclear overlap size (geometrical component) and other sources at a fixed size (intrinsic component) remains a challenge. This problem is addressed by measuring the mean, variance, and skewness of P([p_{T}]) in ^{208}Pb+^{208}Pb and ^{129}Xe+^{129}Xe collisions at sqrt[s_{NN}]=5.

The photo-induced CO-releasing properties of the dark-stable complex [RuCl(CO)L] (L = 2-(pyridin-2-yl)quinoxaline) were investigated under 468 nm light exposure in the presence and absence of biomolecules such as histidine, calf thymus DNA and hen egg white lysozyme. The CO release kinetics were consistent regardless of the presence of these biomolecules, suggesting that they did not influence the CO release mechanism. The quinoxaline ligand demonstrated exceptional cytotoxicity against human acute monocytic leukemia cells (THP-1), with evidence of potential DNA damage ascertained by comet assay, while it remained non-toxic to normal kidney epithelial cells derived from African green monkey (Vero) cell lines.

Group 1 innate lymphoid cells (ILCs) encompass NK cells and ILC1s, which have non-redundant roles in host protection against pathogens and cancer. Despite their circulating nature, NK cells can establish residency in selected tissues during ontogeny, forming a distinct functional subset. The mechanisms that initiate, maintain, and regulate the conversion of NK cells into tissue-resident NK (trNK) cells are currently not well understood.

Gene expression is a multi-step process that converts DNA-encoded information into proteins, involving RNA transcription, maturation, degradation, and translation. While transcriptional control is a major regulator of protein levels, the role of post-transcriptional processes such as RNA processing and degradation is less well understood due to the challenge of measuring their contributions individually. To address this challenge, we investigated the control of gene expression in Trypanosoma brucei, a unicellular parasite assumed to lack transcriptional control.
