Published: February 2025

AbstractLatino immigrant workers have been an exploited community within many dangerous workforces, but especially within the agricultural industry. They are a crucial population for the labor and economy of the U.S., yet Latino farmworkers report feeling expendable, discriminated against, and exposed to hazardous working conditions. Due to these experiences, it is essential to explore the resources that farmworkers find valuable in improving their working conditions. This study draws upon qualitative interviews conducted with 41 Latino farmworkers in Oregon. Themes pertaining to work and nonwork resources were uncovered through thematic analysis, illustrating that farmworkers receive support from their proximal communities and feel empowered by them, but lack support from their distal communities and need basic work necessities, fair wages, supportive supervisors, legislative labor protection, and a pathway to citizenship. Findings make clear that employers and elected officials must do more to advocate for Latino immigrant farmworkers and provide resources to protect their well‐being. We demonstrate the need for future research related to changes in farmworkers' resources over time, their reporting of workplace violations, the impact of labor legislation on their health, and how information sharing or unionization occurs among farmworkers.

AbstractCharged channels are considered an effective design for achieving efficient monovalent cation transport; however, it remains challenging to establish a direct relationship between charge microenvironments and ionic conductivity within the pores. Herein, we report a series of crystalline covalent organic frameworks (COFs) with identical skeletons but different charge microenvironments and explore their intra‐pore charge‐driven ion transport performance and mechanism differences. We found that the charged nature determines ion‐pair action sites, modes, host‐guest interaction, thereby influencing the dissociation efficiency of ion pairs, the hopping ability of cations, and the effective carrier concentration. The order of transport efficiency for Li+, Na+, and H+ follows anion > zwitterion > cation > neutrality. Ionic COFs exhibit up to 11‐fold higher ionic conductivity than neutral COFs. Notably, the ionic conductivity of anionic COF achieves 2.0 × 10−4 S cm−1 for Li+ at 30 °C and 3.8 × 10−2 S cm−1 for H+ at 160 °C, surpassing most COF‐based ionic conductors. This COF platform for efficient ion migration and stable battery cycling in lithium‐metal quasi‐solid‐state batteries has also been verified as proof of concept. This work offers new insights into the development and structure‐activity relationship studies of the next generation of solid‐state ionic conductors.
Abnormal Blueshift of Mn d−d Emission Unlocked by Decreasing Phonon Coupling under High Pressure

Published: February 2025

AbstractMn d−d emission has been a star transition‐metal activated phosphors that were extensively used in optoelectronic devices. However, due to the complex and elusive luminescence mechanism, the full potential of this material remains largely untapped. Here, we designed a core–shell structure of MnS@CdS quantum dots (QDs) to investigate the effect of the internal strain on the Mn emission. Upon pressure processing, an unexpected blueshift of Mn emission was achieved. When the pressure reached a pressure of 2.1 GPa, the conventional redshift of Mn emission reappeared. Remarkable color transition from red to orange and then back to red was observed during pressure treatment. Further analysis revealed that the application of external pressure facilitated the diffusion of Mn atoms into the CdS shell, strengthened host‐dopant coupling and mitigated the lattice mismatch rate within the MnS@CdS QDs. These factors resulted in a reduction in phonon coupling strength and an increase in energy transfer efficiency from the exciton of the CdS host lattice to the Mn dopants, thus ultimately accounting for the abnormal blueshift of Mn d−d emission. Our findings represent a significant breakthrough in the quest for precise control and regulation of Mn‐related emission, offering insights into the underlying luminescence mechanism of Mn emission.

Published: February 2025

AbstractEfficient separation and purification of methane is a key step in promoting its wide application as an environmentally friendly energy carrier and an important chemical raw material. Development of single solid adsorbents simultaneously combining robust structure, high separation capacity, and easy performance recovery is highly desired but quite a challenge for realizing methane depuration. In the present study, we report an ultramicroporous hydrogen‐bonded organic framework compound constructed from a tetracyano bithiophene‐functionalized ligand. Similar to the acting principle of enzymes, multisite supramolecular interactions endow the material with not only extraordinary chemical stability in wide pH range including 12 M HCl and 20 M NaOH solutions but also highly selective recognition of acetylene and carbon dioxide over methane. The packing densities and adsorption selectivities toward acetylene and carbon dioxide are the highest reported for the hydrogen‐bonded organic framework materials. Dynamic breakthrough experiments demonstrate its highly efficient methane purification ability from binary and even ternary mixed gases, with not only methane productivities up to 2.34 mol kg−1 but also moderate regeneration energy. Furthermore, the title compound can be easily regenerated in almost quantitative yield via simple rato‐evaporation of its dichloromethane solution once its activity is attenuated or lost.

AbstractThe oxygen evolution reaction (OER) in water electrolysis is a kinetically sluggish reaction that requires catalysts with high electrocatalytic activity. Cobalt oxide (CoOx) is among the best performing OER catalysts and has been reported to have “bulk activity” with active sites distributed within the material. Herein, we examined the distribution of OER activity over μg cm−2 loaded CoOx deposited on anti‐corrosive Ti substrate in 1 M KOH with and without various cations with chloride (X−Cl, X=Li, Na, K). Depth‐resolved X‐ray absorption spectroscopy and depth‐profiling X‐ray photoelectron spectroscopy were employed. In a thin sample with ~20 nm thickness, uniform oxidation was observed, but a thicker sample with ~80 nm thickness had active oxidized phases close to the surface and an unexpected inactive Co0 phase concurrently occupying about three‐quarters of the CoOx layer in the depth direction, which accounted for the mass activity loss. The formation of Co0 in the bulk is attributed to the galvanic replacement reaction between CoOx and the metallic Ti substrate, which is not observed on the carbon substrate. Operando Raman spectroscopy demonstrated that the type of cations rather than Cl− impacts the OER performance likely due to their interaction with superoxo species.

AbstractThe polymerization pathway of contaminants rivals the traditional mineralization pathway in water purification technologies. However, designing suitable oxidative environments to steer contaminants toward polymerization remains challenging. This study introduces a nitrogen‐oxygen double coordination strategy to create an asymmetrical microenvironment for Co atoms on Ti3C2Tx MXenes, resulting in a novel Co‐N2O3 microcellular structure that efficiently activates peroxymonosulfate. This unique activation capability led to the complete removal of various phenolic pollutants within 3 min, outperforming the representative Co single‐atom catalysts reported in the past three years. Identifying and recognizing reactive oxygen species highlight the crucial role of ⋅O2−. The efficient pollutant removal occurs through a ⋅O2−‐mediated radical pathway, functioning as a self‐coupling reaction rather than deep oxidation. Theoretical calculations demonstrate that the electron‐rich pollutants transfer more electrons to the catalyst surface, inducing the reduction of dissolved oxygen to ⋅O2− in the Co‐N2O3 microregion. In a practical continuous flow‐through application, the system achieved 100 % acetaminophen removal efficiency in 6.5 h, with a hydraulic retention time of just 0.98 s. This study provides new insights into the previously underappreciated role of ⋅O2− in pollutant purification, offering a simple strategy for advancing aggregation removal technology in the field of wastewater treatment.

AbstractIntrinsically photothermal‐responsive soft actuators possessing reconfigurability have attracted great attention due to their ability to change their actuation mode to satisfy diverse practical applications. However, challenges remain in designing and fabricating organic photothermal molecules featuring polymerizable or cross‐linkable groups, especially those with multifunctional properties. Here, a novel class of versatile light‐driven reconfigurable liquid crystal elastomer (LCE) materials, denoted as PUOLCE, has been developed. The multifunctional dynamic covalent organic photothermal molecules, serving as chain extenders, photothermal agents, and dynamic covalent bond precursors, are chemically bonded into LCEs, thereby endowing the LCEs with photothermal‐responsiveness and dynamic properties. The intrinsic photothermal effect of PUOLCE allows the exchange reaction of dynamic oxime‐carbamate bonds to undergo rapid welding under near‐infrared (NIR) light. Leveraging the NIR‐assisted welding strategy, the PUOLCE‐based building units are capable of assembling into various complex actuators with new deformation modes. Besides, the assembled actuators can be easily reconfigured to perform different mechanical tasks (e.g., flower blooming, grasping objects, and elevating objects) under NIR illumination. Furthermore, the PUOLCE actuators can be controlled globally or locally for light‐driven locomotion by controlling the area exposed to the NIR irradiation. This work provides insights into the development of adaptive soft actuators with tunable shape‐morphing capabilities.
Kauzmann Paradox, Supercooling, and Finding Order in Chaos
Authors: Martin Andrew , Thuo Martin 
Published: February 2025

AbstractPrediction of a liquidus state with lower entropy than the corresponding solid at Kauzmann temperature (Tk), and associated entropy catastrophe/paradox, remains an enigma. Despite efforts to resolve this paradox for nearly 80 years, no unifying resolution has been reported. Potential resolutions to the Kauzmann paradox rely on an ideal glass transition, however, this limits the interpretation of Tk as an equilibrium critical point rather than an instability. Focusing on entropy, statistical mechanics and non‐equilibrium dynamics becomes a key tenet in resolving this paradox. Expansion in phase space beyond 2D and consideration of Tk as a non‐equilibrium critical point is necessary to understand the extent of liquid relaxation beyond Tk. In this review, we provide an entropic perspective of the relaxation behavior of supercooled liquids, associated expanded phase diagram, and the potential resolution to the Kauzmann paradox. This work integrates the historical evolution of our understanding of entropy/thermodynamics with modern interpretation of quantum states through renormalization group and thermodynamic speed limits.

AbstractCalendar aging occurring during high‐temperature storage has long plagued practical realization of long‐life, high‐safety lithium‐ion batteries (LIBs). Generally, the aging process is ascribed to the hydrolysis reaction of fluorine‐containing electrolyte salt that generates hydrofluoric acid and chemically corrodes the anode surface. Nevertheless, the underlying mechanism about electrolyte degradation, HF generation and surface corrosion remains concealed for various electrolytes. In this work, we employed in situ liquid time‐of‐flight secondary ion mass spectroscopy to resolve the chemical evolution during high‐temperature calendar aging in the bulk of the electrolyte and at the anode/electrolyte interface. Two conventional salts, LiPF6 and Li bis(fluorosulfonyl)imide (LiFSI), were employed for comparison. We identify that the high‐temperature hydrolysis of LiPF6 preferentially occurs when the anion aggregates ([PF6+LiPF6]−) are attacked by trace H2O. HPO2F2, HF and LiF are generated and assist formation of an inorganics‐rich solid electrolyte interphase (SEI), improving anode stability against parasitic reactions. The LiFSI‐based electrolyte does not involve hydrolysis, which facilities the formation of an organics‐rich SEI. Nevertheless, the SEI does not passivate the anode surface and could induce severe corrosions via electron tunneling at a high temperature. Our work offers original insights into rational design of electrolyte and interface for high‐energy, long‐calendar‐life LIBs.
“Waking Up Someone Who Is Sleepwalking” Daniel Ellsberg, Denial, Anti‐Thought and the Nuclear Threat
Authors: Gabriel Peter , Levine Howard 
Published: February 2025

ABSTRACTDaniel Ellsberg was an outspoken critic of the nuclear arms race, American nuclear war fighting strategy and the policy of deterrence based on so‐called mutually assured destruction. With courage and a deep moral conviction, he raised an often‐lone voice challenging our denial of the world annihilating potential of a nuclear exchange. His passing offers us a chance to reflect psychoanalytically on the minimization and denial of this and other world threatening existential threats and the omnipotent, hubristic belief in the assumed perfectibility of technology—the absolute conquest of nature by humankind. Together, the twin harbingers of mindlessness, silence and refusing to see, comprise a foundation on which rests the dangerous anti‐thought linked to the possibilities of omnicide and world destruction.

Published: February 2025

ABSTRACTHigher Education programming courses usually present high levels of student failure and drop‐out rates. Given this context, the use of educational video games is proposed as a strategy to increase the students' motivation and engagement, thus helping diminish such rates. However, there is a lack of empirical studies examining such effects, especially when they are proposed outside the formal curriculum (i.e., extracurricular) and when the students are enrolled in different Higher Education bachelors. This paper presents a cross‐sectional study following a between‐subjects design with 315 students (168 assigned to the experimental condition, 147 to the control condition) enrolled in one of the following bachelors: B.S. in Computer Science (where programming is a core subject), and B.S. in Statistics (where it is not). The study spanned two consecutive academic years. The outcomes were evaluated through a pre‐/post‐test schema and comparison of final course results to measure the effect on learning (objective assessment) and a survey to get the students' perceptions (subjective assessment). In addition, the level of participation was analyzed and compared between bachelors, considering the optional nature of the activity. Results show statistically significant differences in learning outcomes between the students in the experimental condition and those in the control group, without clear differences between Bachelors (the results are positive for both). In the subjective assessment and participation, the results are also positive, but, in this case, statistically significant differences between bachelors have been observed. These positive outcomes suggest its potential applicability to other Higher Education and Engineering courses.

ABSTRACTObjectivesPrevious research reports self‐affirmation interventions to be efficacious in enhancing many life outcomes of normal individuals, but limited research has assessed its restorative and preserving capacities to enhance and maintain the self‐esteem of individuals with subclinical depressive tendencies.MethodsThis study employed an experimental research design. Eighty participants (age range = 22–27 years) with subclinical depression were chosen using purposive sampling and were randomly assigned in equal numbers to the experimental and control conditions and their self‐esteem was measured at pre‐intervention, post‐intervention and follow‐up intervals.ResultsResults showed that the experimental group participants evoked significantly higher mean scores (F(1, 76) = 29.20, p < 0.001, η2 = 0.28) on self‐esteem as compared to the control group at post‐intervention (Control: Mean (SD) = 17.48 (2.73); Experimental: Mean (SD) = 51.43 (3.29)) and follow‐up (Control: Mean (SD) = 18.28 (2.72); Experimental: Mean (SD) = 48.65 (3.74)). There was a significant difference in the mean scores of the self‐esteem of the experimental group participants during post‐intervention and follow‐up (F(2, 152) = 6.50, p = 0.002, η2 = 0.08). These findings were evident in the conditions' (experimental, control) and intervals' (pre‐intervention, post‐intervention, follow‐up) main and interaction effects: F(2, 152) = 6.54, p < 0.002, η2 = 0.08; and F(2, 152) = 3.87, p < 0.023, η2 = 0.05. The size of these effects ranged from very low, low, to medium (η2).ConclusionThe findings revealed the restorative and preserving capacities of this self‐affirmation intervention for self‐esteem. The positive outcomes of the self‐affirmation intervention may have been produced as result of the activation of meaning, positive cognitions and positive relationships.
Therapeutic Relationship Through the Lenses of the Real Relationship, Therapeutic Alliance and Attachment to the Therapist: In Search of a Synthesis
Authors: Ribeiro Pedro Rodrigues , Neto David Dias 
Published: February 2025

ABSTRACTAimThere is an overlap in psychotherapy research and clinical applications between these three views of the therapeutic relationship: the real relationship, the therapeutic alliance and attachment theory.ObjectiveThis study aimed to provide a synthesis by exploring this overlap in the client's perspective on the therapeutic relationship.MethodThe sample included 373 adult clients of individual therapy. An exploratory principal components analysis was conducted.ResultsParallel analysis revealed a five‐component structure generating a final solution explaining 47% of the variance. These components seem to illustrate different clients' needs and views about the relationship and how the therapist might perceive the relationship and their interactions. It presents dimensions such as the need for security in the therapist, the need to be cared for by the therapist, the fear of being genuine to the therapist, working on the goals of therapy and the need for more contact and expanding the therapeutic relationship beyond the boundaries that can be relevant for assessment, clinical decision‐making and responding to a client's core needs.ConclusionThis theoretical perspective may be useful beyond a specific relational construct, stressing the transtheoretical potential of clients' core needs towards the relationship and better preparing therapists to be more responsive to them.

ABSTRACTArtificial intelligence‐powered digital assistants (DAs) offer benefits, but their downsides can hinder user adoption and limit market potential. Although research exists on users' experiences with DAs, less is known about how user characteristics influence perceptions of a ‘dark side’—perceived creepiness. This study explores how perceived creepiness, user characteristics (uncertainty avoidance), and anxieties triggered by DAs (privacy concerns and technology anxiety) relate to distrust and disengagement from DAs. Based on the stressor‐strain‐outcome and person‐environment fit models, a research model was proposed and tested using survey data from 509 DA users analysed with Amos version 29 software. The results reveal that privacy concerns, uncertainty avoidance, and technology anxiety positively influence perceived creepiness and distrust of DAs, leading to disengagement. Moreover, uncertainty avoidance moderates these relationships, with users higher in uncertainty avoidance experiencing a stronger link between privacy concerns/technology anxiety and perceived creepiness. Importantly, the study shows indirect effects mediated by perceived creepiness, with uncertainty avoidance further moderating these indirect relationships. These findings contribute to literature by highlighting the interplay between user characteristics, DA‐induced anxieties, perceived creepiness, and user disengagement with DAs.
