Selective Catalyst Surface Access through Atomic Layer Deposition

Samuel S Hardisty, Shira Frank, Melina Zysler, Reut Yemini, Anya Muzikansky, Malachi Noked, David Zitoun

Catalyst poisoning is a prominent issue, reducing the lifetime of catalysts and increasing the costs of the processes that rely on them. The electrocatalysts that enable green energy conversion and storage, such as proton exchange membrane fuel cells and hydrogen bromine redox flow batteries, also suffer from this issue, hindering their utilization. Current solutions to protect electrocatalysts from harmful species fall short of effective selectivity without inhibiting the required reactions. This article describes the protection of a standard 50% Pt/C catalyst with a V2O5 coating through atomic layer deposition (ALD). The ALD selectively deposited V2O5 on the Pt, which enhanced hydrogen transport to the Pt surface and resulted in a higher mass activity in alkaline electrolytes. Cyclic voltammetry and X-ray photoelectron spectroscopy showed that the Pt was protected by the coating in the HBr/Br2 electrolyte which dissolved …

Spectral ghost imaging for ultrafast spectroscopy

Shir Rabi, Sara Meir, Raphi Dror, Hamootal Duadi, Francesco Baldini, Francesco Chiavaioli, Moti Fridman

We experimentally demonstrate ghost imaging in the frequency domain based on frequency speckle patterns as references. Our method is suitable for measuring the spectrum of ultrafast signals with high repetition rates. We study the reconstruction resolution as a function of the signal periodicity and found the maximal signal periodicity which can be reconstructed. We also study the reconstruction resolution as a function of the speckle size and show that the speckle size determines the quality of the ghost image. Finally, we perform numerical and analytical calculations which agree with our experimental measured results. Our method is simple, broadband, and utilizes a low cost bucket detector for ultrafast spectral measurements.

Broadband complex two-mode quadratures for quantum optics

Leon Bello, Yoad Michael, Michael Rosenbluh, Eliahu Cohen, Avi Pe’er

In their seminal paper, Caves and Schumaker presented a new formalism for quantum optics, intended to serve as a building block for describing two-photon processes, in terms of new, generalized qudratures. The important, revolutionary concept in their formalism was that it was fundamentally two-mode, ie the related observables could not be attributed to any single one of the comprising modes, but rather to a generalized complex quadrature that could only be attributed to both of them. Here, we propose a subtle, but fundamentally meaningful modification to their important work. Unlike the above proposal, we deliberately choose a frequency-agnostic definition of the two-mode quadrature, that we motivate on physical grounds. This simple modification has far-reaching implications to the formalism–the real and imaginary parts of the quadratures now coincide with the famous EPR variables, and our two-mode …

Amorphous Selenium Mie Resonators for Infrared Meta-Optics

Danveer Singh, Michal Poplinger, Avraham Twitto, Rafi Snitkoff, Pilkhaz Nanikashvili, Ori Azolay, Adi Levi, Chen Stern, Gili Cohen Taguri, Asaf Albo, Doron Naveh, Tomer Lewi

Applying direct growth and deposition of optical surfaces holds great promise for the advancement of future nanophotonic technologies. Here, we report on a chemical vapor deposition (CVD) technique for depositing amorphous selenium (a-Se) spheres by desorption of selenium from Bi2Se3 and re-adsorption on the substrate. We utilize this process to grow scalable, large area Se spheres on several substrates and characterize their Mie-resonant response in the mid-infrared (MIR) spectral range. We demonstrate size-tunable Mie resonances spanning the 2-16 um spectral range, for single isolated resonators and large area ensembles, respectively. We further demonstrate strong absorption dips of up to 90% in ensembles of particles in a broad MIR range. Finally, we show that ultra-high-Q resonances arise in the case where Se Mie-resonators are coupled to low-loss epsilon-near-zero (ENZ) substrates. These findings demonstrate the enabling potential of amorphous Selenium as a versatile and tunable nanophotonic material that may open up avenues for on-chip MIR spectroscopy, chemical sensing, spectral imaging and large area metasurface fabrication.

Improvement of the Electrochemical Performance of LiNi0.8Co0.1Mn0.1O2 via Atomic Layer Deposition of Lithium-Rich Zirconium Phosphate Coatings

Sri Harsha Akella, Sarah Taragin, Yang Wang, Hagit Aviv, Alexander C Kozen, Melina Zysler, Longlong Wang, Daniel Sharon, Sang Bok Lee, Malachi Noked

Owing to its high energy density, LiNi0.8Co0.1Mn0.1O2 (NMC811) is a cathode material of prime interest for electric vehicle battery manufacturers. However, NMC811 suffers from several irreversible parasitic reactions that lead to severe capacity fading and impedance buildup during prolonged cycling. Thin surface protection films coated on the cathode material mitigate degradative chemomechanical reactions at the electrode–electrolyte interphase, which helps to increase cycling stability. However, these coatings may impede the diffusion of lithium ions, and therefore, limit the performance of the cathode material at a high C-rate. Herein, we report on the synthesis of zirconium phosphate (ZrxPOy) and lithium-containing zirconium phosphate (LixZryPOz) coatings as artificial cathode–electrolyte interphases (ACEIs) on NMC811 using the atomic layer deposition technique. Upon prolonged cycling, the ZrxPOy- and …

Nanocrystals as Model Systems for Studying the Interplay Between Crystallization and Chirality

Uri Hananel, Assaf Ben Moshe, Gil Markovich, A Paul Alivisatos

The interplay between crystallization and chirality has fascinated chemists for over 170 years now. Many questions deal with the transfer of chirality from molecular level building blocks and crystal capping ligands to the macroscopic morphologies of crystals. Also the interest in nanoscale chiral crystallization and the relationship between chiral ligands and inorganic nanocrystals has recently arose. In this review we highlight several different topics related to studies of the interplay between chirality and crystallization that involve inorganic nanocrystals. Specifically, we differentiate between the effects of chiral molecules on inorganic nanocrystals with chiral or achiral crystal structures. In the first case, chirality may appear both at the atomic‐scale and the particle shape, and in the second case chirality may be induced only at the particle shape level. We also discuss recent progress on the relationship between the …

The advantages of EPR spectroscopy in exploring diamagnetic metal ion binding and transfer mechanisms in biological systems

Shelly Meron, Yulia Shenberger, Sharon Ruthstein

Electron paramagnetic resonance (EPR) spectroscopy has emerged as an ideal biophysical tool to study complex biological processes. EPR spectroscopy can follow minor conformational changes in various proteins as a function of ligand or protein binding or interactions with high resolution and sensitivity. Resolving cellular mechanisms, involving small ligand binding or metal ion transfer, is not trivial and cannot be studied using conventional biophysical tools. In recent years, our group has been using EPR spectroscopy to study the mechanism underlying copper ion transfer in eukaryotic and prokaryotic systems. This mini-review focuses on our achievements following copper metal coordination in the diamagnetic oxidation state, Cu(I), between biomolecules. We discuss the conformational changes induced in proteins upon Cu(I) binding, as well as the conformational changes induced in two proteins involved in Cu(I) transfer. We also consider how EPR spectroscopy, together with other biophysical and computational tools, can identify the Cu(I)-binding sites. This work describes the advantages of EPR spectroscopy for studying biological processes that involve small ligand binding and transfer between intracellular proteins.

Application of molecular catalysts for the oxygen reduction reaction in alkaline fuel cells

Ariel Friedman, Michal Mizrahi, Naomi Levy, Noam Zion, Michael Zachman, Lior Elbaz

The development of precious group metal-free (PGM-free) catalysts for the oxygen reduction reaction is considered as the main thrust for the cost reduction of fuel cell technologies and their mass production. Within the PGM-free category, molecular catalysts offer an advantage over other heat-treated PGM-free catalysts owing to their well-defined structure, which enables further design of more active, selective, and durable catalysts. Even though non-heat-treated molecular catalysts with exceptional performance have been reported in the past, they were rarely tested in a fuel cell. Herein, we report on a molecular catalyst under alkaline conditions: fluorinated iron phthalocyanine (FeFPc) supported on cheap and commercially available high-surface area carbon─BP2000 (FeFPc@BP2000). It exhibits the highest activity ever reported for molecular catalysts under alkaline conditions in half-cells and fuel cells.

Silver Oxygen Reduction Electrocatalyst in Alkaline Medium: Aging and Protective Coating

Anna Kitayev, Melina Zysler, Samuel Hardisty, Miles Page, Ervin Tal-Gutelmacher, David Zitoun

The oxygen reduction reaction (ORR) is a key process in anion exchange membrane fuel cells. The alkaline conditions should allow silver‐based cost‐efficient catalysts to replace platinum group metal materials. However, Ag electrochemical stability or lack of stability in alkaline medium is still to be demonstrated. Herein, Ag catalyst nanoparticles (NPs) are characterized by identical location transmission electron microscopy and X‐ray photoelectron spectroscopy after electrochemical cycling, revealing the losses of activity and surface. Herein, a facile method for enhancing the chemical stability of Ag catalysts in an alkaline environment by depositing a protective polydopamine (PDA) coating is reported. It is enhanced via crosslinking with polyethyleneimine (PEI), on the surface of Ag NPs. The enhanced electrochemical stability of Ag PDA–PEI nanocatalyst via the analysis of ORR polarization curves during …

Rapid ensemble measurement of protein diffusion and probe blinking dynamics in cells

Simon Sehayek, Xiyu Yi, Shimon Weiss, Paul W Wiseman

We present a fluorescence fluctuation image correlation analysis method that can rapidly and simultaneously measure the diffusion coefficient, photoblinking rates, and fraction of diffusing particles of fluorescent molecules in cells. Unlike other image correlation techniques, we demonstrated that our method could be applied irrespective of a nonuniformly distributed, immobile blinking fluorophore population. This allows us to measure blinking and transport dynamics in complex cell morphologies, a benefit for a range of super-resolution fluorescence imaging approaches that rely on probe emission blinking. Furthermore, we showed that our technique could be applied without directly accounting for photobleaching. We successfully employed our technique on several simulations with realistic EMCCD noise and photobleaching models, as well as on Dronpa-C12-labeled β-actin in living NIH/3T3 and HeLa cells. We …

Microbial inhibition and biosensing with multifunctional carbon dots: Progress and perspectives

Moorthy Maruthapandi, Arumugam Saravanan, Poushali Das, John HT Luong, Aharon Gedanken

Carbon dots (CDs) and their doped counterparts including nitrogen-doped CDs (N@CDs) have been synthesized by bottom-up or top-down approaches from different precursors. The attractiveness of such emerging 2D‑carbon-based nanosized materials is attributed to their excellent biocompatibility, preparation, aqueous dispersibility, and functionality. The antimicrobial, optical, and electrochemical properties of CDs have been advocated for two important biotechnological applications: bacterial eradication and sensing/biosensing. CDs as well as N@CDs act as antimicrobial agents as their surfaces encompass functional hydroxyl, carboxyl, and amino groups that generate free radicals. As a new class of photoluminescent nanomaterials, CDs can be employed in diversified analytics. CDs with surface carboxyl or amino groups form nanocomposites with nanomaterials or be conjugated with biorecognition …
