Summary: Pt-Ag nanoalloys show remarkable chemical order depending on their size and composition. Recently, a reversed size-dependent stabilization of ordered nanophases was observed around equiconcentration. In this study, we investigate the composition-dependent chemical ordering in Pt-Ag nanoalloys, revealing a strong Ag segregation on the surface at low silver content and an L1(1) ordered phase in the core at higher silver concentrations, interrupted by a concentric multishell structure in a narrow range of compositions.

Summary: In this study, carbon-negative and neutral methods for producing H2 and other syngas-derived chemicals were tested through chemical looping reforming of methane or glycerol. A chemical looping reactor with dynamically operated packed beds was used to provide the necessary heat and capture CO2. The potential for negative emissions is achieved if the methane or glycerol is from a biological source. Various pressure and temperature conditions were tested, and complete conversion of glycerol and high H2 production were achieved.

Summary: Soft ionic sensors have great potential in future electronic applications. However, one challenge is the mixing of sensing signals due to mechanical deformation and other stimuli. This study proposes a simple strategy for designing stretchable composite electrodes to achieve different strain responses. The study demonstrates the practical fabrication of a highly reproducible strain-neutral ionic sensor, a completely strain-independent temperature sensor, and a shear sensor capable of recognizing shear directions.

Summary: We present a method of deep metal-assisted chemical etching (MACE) using a porous monolithic AgAu layer on crystalline silicon (c-Si) as a cost-effective alternative to deep reactive ion etching (DRIE) for fabricating neutral-colored transparent crystalline silicon photovoltaics (c-Si TPV). By introducing acetonitrile to enhance the interaction between the c-Si surface and Ag precursor, a porous monolithic Ag layer is developed to prevent the uneven etching of c-Si by Ag particles. The durability of this Ag catalyst is further improved by passivation with Au via galvanic replacement (i.e., the porous monolithic AgAu layer), resulting in high-performance c-Si TPV with 13.0% efficiency and 20% neutral-colored transparency, superior to samples fabricated by DRIE (11.5%).

Summary: This study develops a thermal-chemical-fluid-microstructure model for simulating in-situ additive manufacturing (AM) and investigates the role of thermal fluid flow and chemical mixing in rapidly solidification microstructure. The results suggest that heterogeneous nucleation initiates equiaxed grains and anisotropic columnar grain growth occurs in AM. The keyhole acts as a strong stirrer enhancing chemical mixing. This work provides fundamental insights for optimizing the grain structure in AM.

Summary: Aerosol nanoclusters (AN), molecular aggregates suspended in gas with dimensions between 2 and 10 nm, play a crucial role in connecting molecules and gas phase with particles and condensed phase. Understanding the physical and chemical properties of size-resolved AN is essential for studying the formation and evolution of particles in various environments. Current measurement and modeling techniques, although still rudimentary, show potential for closing the gap between gas-phase clusters and nanoparticles by improving instruments and theoretical methods.

Summary: This study evaluated the hourly particle number size distributions (PNSD) from 26 sites in Europe and 1 in the US, focusing on urban background (UB) and traffic (TR) sites. The objective was to describe the characteristics of urban ultrafine particles (UFP) in Europe. The results showed variations in PNC and BC across different regions and site types, with traffic emissions being a major contributor. The study emphasized the need for specific monitoring of PNSD and measurements of <10 nm PNC for assessing the health effects of nanoparticles.

Summary: This study investigates the effect of high relative humidity (RH) on the gas-particle partitioning of biogenic oxidized organic molecules at low temperatures. The results demonstrate that high RH increases the partitioning of semivolatile compounds and leads to a shift in the chemical composition and volatility distribution of organic aerosols towards less oxygenated and more volatile species.

Summary: Iodine is an active trace element in atmospheric chemistry that can destroy ozone and form particles. Its emissions have increased threefold since 1950 and are expected to continue rising. In laboratory experiments, iodooxy hypoiodite (IOIO) was shown to efficiently convert into iodic acid (HIO3) via reactions IOIO + O-3 -> IOIO4 and IOIO4 + H2O -> HIO3 + HOI + O-(1)(2). This laboratory-derived mechanism explains field observations of daytime HIO3 in the remote lower free troposphere and suggests a catalytic role of iodine in aerosol formation.

Summary: New particle formation (NPF) is a global phenomenon that affects climate and contributes to haze, impacting human health. In Beijing, NPF occurs surprisingly during haze days due to high levels of sulfuric acid dimers. The mixing of sulfur dioxide from the residual layer enhances ground level sulfuric acid dimer formation, bridging a gap in understanding NPF in polluted atmospheres.

Summary: The interaction between nitrogen monoxide (NO) and organic peroxy radicals (RO2) has a significant impact on the formation of highly oxygenated organic molecules (HOM), which are key precursors of secondary organic aerosols. Contrary to previous belief, low concentrations of NO can enhance HOM production by modulating RO2 loss and promoting the formation of alkoxy radicals. This challenges the notion that NO monotonically reduces HOM yields and expands the understanding of RO2-NO interactions.

Summary: Ultrafine particles dominate aerosol number concentration in urban environments, with high concentrations reaching up to 106 particles cm-3. Dilution is often used to adapt the measurements, however it is unsuitable for cluster or nucleation mode particles. This study introduces a new nanoparticle diluter sampling system and evaluates its performance in diluting particles down to approximately 1 nm size, while also functioning as an ion precipitator and humidity controller. Initial measurements from ambient traffic emissions are presented.

Summary: The Portable Ice Nucleation Chamber 2 (PINCii) is a new continuous flow diffusion chamber (CFDC) that can measure ice nucleating particles (INPs). PINCii has been engineered to improve upon the limitations of previous CFDCs and offers several possibilities for improved INP measurements. It features low background particle counts, high-spatial-resolution wall-temperature mapping, and a new method for analyzing CFDC data. Additionally, it can be used to study droplet activation processes and extend ice crystal growth. The instrument's capabilities have been demonstrated through a series of experiments. The sources of uncertainty in CFDCs, including particle background, particle loss, and variations in aerosol lamina temperature and relative humidity, have also been quantified and discussed for PINCii. Overall, the importance of this work in developing a more advanced instrument for measuring INPs is rated 9 out of 10.

Summary: The complete chemical characterization of nanoparticles is challenging due to their abundance but negligible mass. This study compares different techniques for the chemical composition analysis of secondary organic aerosol nanoparticles. The experiments were conducted at the CLOUD chamber, and simultaneous measurements were performed using four different techniques. The results generally agree on the important compounds found in the nanoparticles, but each technique captures different parts of the organic spectrum, potentially due to factors such as thermal decomposition or sampling artifacts.

Summary: Highly oxygenated compounds play a significant role in the formation and growth of atmospheric organic aerosol, affecting Earth's radiation balance and global climate. However, the lack of suitable detection techniques has limited our understanding of the contribution and fate of these compounds. In this study, a new online method for measuring highly oxygenated compounds from organic aerosol is presented, which allows for highly time-resolved measurements without sample collection. Results show promising potential for investigating the transformations and fate of these compounds after condensing into the particle phase.

Summary: Highly oxygenated organic molecules (HOMs) are crucial for the formation of secondary organic aerosol (SOA), but the lack of suitable analytical techniques has limited our understanding of particle-phase HOM speciation and its relationship with gas-phase HOM formation. This study used a novel VIA-NO3-CIMS system to investigate the gas- and particle-phase HOM products of a-pinene ozonolysis. The results showed that gas-phase dimer formation was suppressed with the addition of CO or NO, but particle-phase dimers still constituted a considerable fraction of the observed SOA. Overall, the VIA-NO3-CIMS system showed promise for combined online gas- and particle-phase HOM measurements.
