Chronic lymphocytic leukemia (CLL) is characterized by the existence of subsets of patients with (quasi)identical, stereotyped B cell receptor immunoglobulins (BcR IG). Patients in certain major stereotyped subsets often display remarkably consistent clinicobiological profiles, suggesting that the study of BcR IG stereotypy in CLL has important implications for understanding disease...

Analysis method for detecting topological defect dark matter with a global magnetometer network

Masia-Roig, Hector ; A.Smiga, Joseph ; Budker, Dmitry ; Dumont, Vincent ; Gruji, Zoran ; Kim, Dongok ; Kimball, Derek F. Jackson ; Lebedev, Victor ; Monroy, Madeline ; Pustelny, Szymon ; Scholtes, Theo ; Segura, Perrin C. ; Semertzidi, Yannis K. ; Shin, Yun Chang ; Stalnaker, Jason E. ; Sulai, Ibrahim ; Weis, Antoine ; Wickenbrock, Arne

In: Physics of the Dark Universe, 2020, vol. 28, p. 100494

The Global Network of Optical Magnetometers for Exotic physics searches (GNOME) is a network of time-synchronized, geographically separated, optically pumped atomic magnetometers that is being used to search for correlated transient signals heralding exotic physics. GNOME is sensitive to exotic couplings of atomic spins to certain classes of dark matter candidates, such as axions. This work...

A Three-Dimensional Porous Organic Semiconductor Based on Fully sp2 -Hybridized Graphitic Polymer

Byun, Yearin ; Xie, Lilia S. ; Fritz, Patrick Walter ; Ashirov, Timur ; Dincă, Mircea ; Coskun, Ali

In: Angewandte Chemie International Edition, 2020, vol. 59, no. 35, p. 15166-15170

Dimensionality plays an important role in the charge transport properties of organic semiconductors. Although three‐dimensional semiconductors, such as Si, are common in inorganic materials, imparting electrical conductivity to covalent three‐ dimensional organic polymers is challenging. Now, the synthesis of a three‐ dimensional π‐conjugated porous organic polymer (3D p‐POP) using...

Covalent triazine frameworks incorporating charged polypyrrole channels for high-performance lithium–sulfur batteries

Kim, Jiheon ; Elabd, Ahmed ; Chung, Sung-Yoon ; Coskun, Ali ; Choi, Jang Wook

In: Chemistry of Materials, 2020, vol. 32, no. 10, p. 4185–4193

Organosulfur polymers have emerged as promising electrode materials for lithium– sulfur (Li–S) batteries, mainly because of their ability to incorporate and stabilize high sulfur content. The low ionic and electronic conductivity of these polymers, however, limit their cycling performance at high active mass loadings. Moreover, Li–polysulfide (Li–PS) shuttling, a fatal phenomenon in...

The Mre11-Nbs1 interface is essential for viability and tumor suppression

Kim, Jun Hyun ; Grosbart, Malgorzata ; Anand, Roopesh ; Wyman, Claire ; Cejka, Petr ; Petrini, John H.J.

In: Cell reports, 2017, vol. 18, no. 2, p. 496-507

The Mre11 complex (Mre11, Rad50, and Nbs1) is integral to both DNA repair and ataxia telangiectasia mutated (ATM)-dependent DNA damage signaling. All three Mre11 complex components are essential for viability at the cellular and organismal levels. To delineate essential and non-essential Mre11 complex functions that are mediated by Nbs1, we used TALEN-based genome editing to derive Nbs1...

Silver(I) complexes with 4,7-phenanthroline efficient in rescuing the zebrafish embryos of lethal Candida albicans infection

Pavic, Aleksandar ; Savić, Nada D. ; Glišić, Biljana Đ. ; Crochet, Aurélien ; Vojnovic, Sandra ; Kurutos, Atanas ; Stanković, Dalibor M. ; Fromm, Katharina M. ; Nikodinovic-Runic, Jasmina ; Djuran, Miloš I.

In: Journal of Inorganic Biochemistry, 2019, vol. 195, p. 149–163

Five novel silver(I) complexes with 4,7-phenanthroline (4,7-phen), [Ag(NO3-O)(4,7- phen-μ-N4,N7)]n (1), [Ag(ClO4-О)(4,7-phen-μ-N4,N7)]n (2), [Ag(CF3COO-O)(4,7- phen-μ-N4,N7)]n (3), [Ag2(H2O)0.58(4,7-phen)3](SbF6)2 (4) and {[Ag2(H2O)(4,7- phen-μ-N4,N7)2](BF4)2}n (5) were synthesized, structurally elucidated and biologically evaluated. These complexes showed selectivity towards Candida spp....

Prospect for supramolecular chemistry in high-energy-density rechargeable batteries

Kwon, Tae-woo ; Choi, Jang Wook ; Coskun, Ali

In: Joule, 2019, vol. 3, no. 3, p. 662–682

The quest for new electrode materials for Li-ion batteries with high energy densities beyond conventional intercalation-based electrodes has gained significant attention due to the increasing demand for advanced portable devices and electric vehicles (EVs). Among various candidates, the most promising electrode materials along this direction are silicon and Li metal for anodes and sulfur for...

Bimetallic metal organic frameworks with precisely positioned metal centers for efficient H2 storage

Kim, Daeok ; Song, Kyung Seob ; Buyukcakir, Onur ; Yildirim, Taner ; Coskun, Ali

In: Chemical Communications, 2018, vol. 54, no. 86, p. 12218–12221

We demonstrated that the ratio and position of two different metal ions, Pd and Cu, can be precisely controlled within MOFs through predesigned metal clusters. These MOF structures incorporating Pd–Cu paddle wheel units were synthesised simply by reacting Pd–Cu acetate metal clusters and tritopic organic linkers at room temperature. Pd–Cu open metal sites were found to be uniformly...

Energy band-gap engineering of conjugated microporous polymers via acidity-dependent in situ cyclization

Lee, Jiyoung ; Buyukcakir, Onur ; Kwon, Tae-woo ; Coskun, Ali

In: Journal of the American Chemical Society, 2018, vol. 140, no. 35, p. 10937–10940

Conjugated microporous polymers (CMPs) offer a unique structure integrating π- conjugated backbone into a porous network for the simultaneous transport of charges and materials. However, tuning electronic properties of CMPs so far has been limited to an approach of varying the monomers, and the precious metal catalysts are inevitably needed for the C–C coupling reaction. Here, we present a...
