Summary: The study investigated the dynamic behavior of an on-board rotor system supported by squeeze film damper (SFD) considering fluid inertia under parametric excitations and external forces induced by base motions. The analysis showed that the pressure distribution is sensitive to oil-film inertia, reducing radial force while increasing tangential force when the journal whirls at a large eccentricity ratio. Overall, the study provides a flexible approach to calculate the dynamic behavior of SFD-rotor system under base motions, offering technical support for dynamic design of on-board rotor systems in gas turbines.

Summary: Sequential asymmetric hydrogenation of 3-amino-4-chromones using Rh catalyst has been achieved for the first time. The process involves an unprecedented dynamic kinetic resolution under neutral conditions, resulting in high yields of (S,R)-3-amino-4-chromanols with excellent enantio- and diastereoselectivities. Mechanistic studies suggest that the process proceeds via stereomutation pathway rather than traditional racemization.

Summary: In this study, a novel model is constructed to describe the steady-state contact angles of liquid droplets on a wetted substrate. The model utilizes the standard disjoining pressure approximation to balance the intermolecular forces and surface tension, resulting in a smooth liquid surface shape. It is found that for large droplets, the contact angle is independent of droplet size and can be determined by the surface tension and disjoining pressure parameters through a simple formula.

Summary: This paper investigated the motion properties and sequential Radar Cross Section (RCS) properties of airborne corner reflector (ACR) in order to understand the jamming principle of this apparatus. It derived the motion model of the ACR and established the dynamic sequential RCS model of ACR array. The results showed that the flight process of the ACR can be divided into two stages: fast falling and steady falling. The simulation of dynamic sequential RCS model demonstrated an obvious depolarisation effect in the fast falling stage.

Summary: This paper studies the problem of sequential formation control in multiagent systems, where a team of agents needs to establish needed formations at user-defined times. To address this problem, the authors propose a finite-time distributed control architecture based on multiplex networks over directed graph topologies. The key features of the proposed architecture are the ability to spatially alter the formation without global information exchange and the ability to establish a specific formation determined by leader agent(s) at user-defined times. The authors provide system-theoretical analysis using time transformation approach and Lyapunov stability theory, and demonstrate the ability of the proposed architecture through a numerical example.

Summary: This study reports an approach and mechanism for minimizing proton defects in alkylammonium lead trihalide perovskite (ALHP) crystals by adding ionized halides to the perovskite precursor solution. The researchers found that the ionized halides induced proton transfer from H2O to the alkylammonium cation in the precursor solution, stabilizing the ALHP crystals. By examining the fundamental characteristics of ALHP and its precursors, the findings from this work will guide the development of highly stable ALHP crystals, enabling efficient and stable optoelectronic ALHP devices.

Summary: This article reports an elegant method to integrate perovskites and Si-heterojunction tandem solar cells using an ultra-thin indium tin oxide (ITO) interlayer, which overcomes the efficiency limit of single junction solar cells. It is found that a 1.7 nm ITO interlayer provides efficient interfacing between the silicon and perovskite subcells. Thinner ITO interlayers result in discontinuous films, while thicker ITO interlayers are less effective in localizing shunts.

Summary: State-of-the-art perovskite-perovskite tandem solar cells use a water-based PEDOT:PSS hole transport layer in the low bandgap subcell, but its use is limited due to moisture sensitivity and insulating property. We overcome this limitation by using a water-free and PSS-free PEDOT-based hole transport layer, achieving higher efficiency and reproducibility in perovskite-perovskite tandems.

Summary: Gas-quenching is a promising technique for the fabrication of perovskite films in order to promote the commercialization of perovskite solar cells. However, it is often difficult to obtain high-quality perovskite films when handling with methylammonium-free (MA-free) perovskites. In this study, formate additives are employed to regulate the crystallization of MA-free perovskite and improve the quality of perovskite films.

Summary: The reduction in space hardware costs has enabled commercial space to emerge. Radiation-hard organometal halide perovskite solar cells (PSCs) have the potential for low-cost and high-efficiency space applications. The study tested high-efficiency PSCs with different hole transport materials (HTMs) and dopants under proton irradiation, and found that PSCs with specific HTMs and dopants were more tolerant to higher-fluence radiation. The insights gained from this study will contribute to the development of low-cost lightweight solar cells for space applications.

Summary: The past decade has witnessed the rapid rise of a new class of solar cells based on mixed organic-inorganic halide perovskites. The power conversion efficiency of halide perovskite solar cells has exceeded 25% for single-junction devices and 30% for tandem devices. Twin domains within polycrystalline grains play important roles in ionic and charge carrier transport properties, although their mechanisms are not fully understood. This study combines molecular dynamic simulations and nanoscale scanning probe microscopy investigations to reveal unique properties of the twin domains that contribute to ion migration and influence charge separation and collection. The findings highlight the significance of nanoscale intragrain features for the development of high-efficiency perovskite solar cells.

Summary: Measuring specific contact resistivity (pc) is crucial for interface engineering in high efficiency solar cells. The Transfer Length Method (TLM) is commonly used for evaluating layer sheet resistance (Rsheet) and pc, but it is not suitable for metal/Transparent Conductive Oxide (TCO) interface evaluation in silicon heterojunction (SHJ) cells. This study investigates the parameters that restrict current confinement within the TCO, including mid-gap trap density (Dit) at the a-Si:H/c-Si interface and the activation energy (Ea = Ec - EF) variation of a-Si:H contact layers.

Summary: The phenomenon of ribbon lengthening in PV modules exposed to thermal cycling is not well explained in the literature. In this study, a three layers model is proposed to explain this effect, and the predictions of the model are validated through finite element method simulations and experiments. The results show that the model predictions are consistent with the indirect measurements, but not with the direct measurements. Additionally, it is inferred that the encapsulant plays a role after the solder failure.

Optical absorption mechanisms in qNL arrays were investigated using near-field scanning optical microscopy (NSOM), revealing that the enhancement is a result of the combination of effective antireflection coating, increased optical interactions between adjacent dielectrics for elevated light trapping, and strong light concentration due to the presence of qNLs.
