Rapid advances in electronics has led to a significant increase in electromagnetic radiation from electronic devices, posing potential threats to human health. Developing lightweight, high‐performance, and green electromagnetic interference (EMI) shields is crucial for mitigating electromagnetic pollution. EMI shielding research over the last decade has provided numerous alternatives to metal shields using carbon nanotubes, graphene, MXenes, etc. However, these shields are mostly reflection‐dominant, just like metals, due to their high conductivity, offering hardly any remedy to the secondary pollution issue. Thus, the research focus has shifted to reduce the reflection and develop absorption‐dominant EMI shields. A green index, defined as the ratio of absorption over reflection, must be well over 1 and preferably even as high as 10. This article provides an in‐depth review of the theoretical foundations of EMI shielding, highlighting various loss mechanisms, along with recent advances in absorption‐dominant EMI shields. Various strategies to reduce reflection through better impedance matching, including foam and aerogels, semiconductor fillers, magnetic fillers, gradient conductivity shields, conductivity‐magnetic dual gradient, segregated structures, printed shields, metastructures and others are discussed . Finally, design strategies of absorption‐dominant shields are analyzed, and current challenges and potential pathways are outlined to guide future advancements and facilitate practical implementation.

Mn‐ and Fe‐based layered oxides are candidates for sodium‐ion battery cathodes due to their high specific capacity and raw material abundance. However, rapid capacity degradation due to irreversible phase transitions during electrochemical cycling is a major challenge. In this study, we explore anionic substitution with A = F − , Cl − , and Br − of Na 0.66 Fe 1/3 Mn 2/3 O 2−x A x (with x < 0.2), both experimentally and through density functional theory calculations. We demonstrate that substitution with Cl − /Br − is challenged by their larger ionic radii compared to oxygen ions, following the classical Goldschmidt rule. Yet, we reveal the successful aliovalent F − for O 2− substitution with a solubility limit at x = 0.035, determined by quantitative phase analysis from powder X‐ray diffraction (P XRD), Rietveld refinement, and Raman spectroscopy. Moreover, galvanostatic electrochemical cycling tests on x = 0.02 mol F‐substituted cathodes showed 15% higher capacity retention after 75 cycles, when compared with the unsubstituted material. Using in situ XRD, we show that the incorporation of F − alters the kinetics of the P2‐P`2 transformation in the low voltage range in favor of the P2 phase. This highlights low‐level F‐substituted P2‐type layered oxides as promising candidates for resource‐efficient, high‐capacity cathodes in sodium‐ion batteries.

Nanostructured Interfaces Zinc phosphate is a novel material to protect perovskite from moisture. However, mid-gap states involving Zn, O, Pb, and iodine are created at the interface. Halide additives could passivate these defects and recover the band gap of perovskite even with distorted interface by drawing charge density onto themselves that had previously centred on oxygen ions at interface.

Piezo‐optoelectronic coupling, the direct modulation of photoresponse by strain‐induced piezoelectric polarization, is a theoretically promising route to adaptive, programmable optoelectronics, yet it remains experimentally elusive in scalable two‐dimensional systems. Here, we present large‐area monolayer MoS 2 as a robust platform for probing and controlling this coupling at the atomic limit, and a single device made on it demonstrates integrated functionality for energy generation, strain sensing, and photodetection within a unified configuration. Using dual AC resonance tracking piezoresponse force microscopy, we quantify an out‐of‐plane piezoelectric coefficient ( = 0.64 pm/V) and demonstrate a pronounced, strain‐tunable internal piezoelectric polarization that enables exciton dissociation under low bias and illumination, distinct from conventional photodetection approaches. While absolute responsivity is modest, the observed strain‐induced enhancement of photocurrent and the clear correlation with measured piezoresponse reveal that mechanical deformation can be leveraged as a precise control knob for charge separation and light–matter interaction in ultrathin semiconductors. These findings provide direct experimental insight into piezo‐optoelectronic coupling, establishing monolayer MoS 2 as a multifunctional and scalable platform for future studies of coupled electromechanical photonic phenomena and for the development of programmable optoelectronics, hybrid sensors, and next‐generation flexible devices.

Cellular membranes are inherently heterogeneous in their lipid composition and can exhibit varying degrees of stiffness and phase separation. Many proteins that reversibly traffic between membrane compartments and/or domains are modified with lipid anchors that enable them to bind and localize to desired membrane regions. Inspired by the lipidation patterns of membrane trafficking elements and using DNA origami as bioengineering material, this work aims to develop biomimetic lipid‐anchored DNA nanostructures that selectively bind to and reversibly shuttle between membranes of different rigidities. Here, origami structures are functionalized with different types and numbers of lipophilic groups, namely cholesterol, tocopherol, oleyl, palmitoyl, and stearoyl, which mimic important physicochemical properties of naturally occurring lipid anchors. Their membrane interaction and phase selectivity toward homogeneous and liquid‐disordered/liquid‐ordered phase‐separated giant unilamellar vesicles are quantitatively characterized by fluorescence confocal microscopy. Key findings show that the lipid‐anchored DNA nanostructures selectively bind to varying membrane phases, depending on the type of anchor and membrane composition/rigidity. Finally, by using strand displacement to control the dimerization of DNA nanostructures carrying distinct lipid anchors, a reversible shuttle between different membrane domains and vesicles is accomplished, recapitulating key principles of membrane trafficking in vitro and opening new perspectives for more precise membrane‐active nanocarriers.

Predicting the structurally diverse Cas12 nucleases remains challenging for general protein modeling algorithms, hindering rational engineering to enhance their genome‐editing capabilities. Here we present Cas12Fold, a deep learning framework tailored to Cas12 proteins. Cas12Fold leverages the deep evolutionary information from Cas12‐focused sequences and structures, and employs an iterative structure‐based alignment strategy to resolve conformational complexity. This approach achieves superior accuracy compared to existing methods in modeling key functional domains and capturing alternative conformations. Cas12Fold improves the structure predictions for previously refractory Cas12 proteins, including the phage‐encoded Casλ, a type V enzyme with extensive sequence and structural diversity. Accurate models generated by Cas12Fold enable robust inference of mechanistically critical residues. Guided by these predictions, structure‐based mutagenesis of DNA‐binding sites enhanced the genome‐editing efficiency of Cas12j.4. Cas12Fold thus provides a robust and generalizable platform for both mechanistic studies and the rational engineering of CRISPR–Cas12 systems.

Bulk‐type all‐solid‐Li batteries based on inorganic solid electrolytes (SEs) are considered promising candidates for next‐generation energy storage systems for their potential to overcome the limitations of current lithium‐ion batteries, such as safety concerns, narrow operating temperature. Following the intensive efforts to search for affordable sulfide SEs, recently, chloride SEs are in the spotlight for their better high‐voltage stability and potentially lower cost than the sulfide counterparts. However, many chloride SEs exhibiting appreciable ionic conductivity adopt rare‐earth metals, which arises the motivation to search for new chloride SEs based on earth‐abundant minerals. Herein, Li 6−x Fe 1−x Al x Cl 8 (0 ≤ × ≤ 0.8) SEs exhibiting significantly improved ionic conductivity of 3.9 × 10 −5 S cm −1 at 25°C for Li 5.5 Fe 0.5 Al 0.5 Cl 8 compared to Li 6 FeCl 8 (3.1 × 10 −6 S cm −1 ) are reported. The formation of a metastable spinel‐like phase was observed for Li 5.5 Fe 0.5 Al 0.5 Cl 8 prepared by mechanical ball‐milling. Furthermore, its electrochemical properties as a catholyte were examined, coupled with a LiFePO 4 cathode active material.

Cu 3 (HHTP) 2 , a benchmark MOF, combines intrinsic conductivity, long‐lived excited states, and ordered porosity, making it attractive for energy, sensing, and optoelectronics. Yet, its integration has been largely limited to flat substrates with restricted surface area and poor architectural versatility. Here, we present a robust strategy for hybrid integration by applying liquid‐mediated sintering to flame spray pyrolysis‐derived SnO 2 , forming nano–microcluster arrays that retain high porosity and mechanical stability during vapor‐assisted MOF synthesis. Systematic comparison of three copper precursors reveals distinct effects on Cu 3 (HHTP) 2 morphology, interconnectivity, and film quality. The resulting SnO 2 /Cu 3 (HHTP) 2 hybrid films establish p–n heterojunctions and show proof‐of‐concept photovoltaic activity, maintaining the solar‐blind response of SnO 2 . This work demonstrates a generalizable route for coupling conductive MOFs with porous semiconductor scaffolds, enabling mechanically stable, high–surface area hybrids for future optoelectronic and sensing applications.

Spintronic devices utilizing spin‐orbit torque mechanisms still face challenges including high drive currents, the necessity of external magnetic fields, and sensitivity to crystallographic orientation. Here, we demonstrate field‐free deterministic magnetization switching in perpendicularly magnetized Fe 3 GeTe 2 (FGT) through WTe 2 /FGT/WTe 2 van der Waals heterostructures. By exploiting the strong charge‐to‐spin conversion of WTe 2 —a type‐II Weyl semimetal—the trilayer design enables out‐of‐plane antidamping torques generation regardless of current direction along the a or b crystallographic axis. In perpendicularly aligned devices, polarity‐dependent magnetization switching is achieved without external fields at 150 K, with a threshold current of approximately ±5–7 mA. In contrast, parallelly aligned devices exhibit unidirectional switching from downward to upward magnetization states, independent of current polarity. Such crystallographic‐orientation‐independent switching eliminates the need for precise crystallographic measurements during fabrication, thereby significantly simplifying device integration. This article provides a pathway toward scalable and energy‐efficient spintronic devices for memory and neuromorphic computing applications.
