Triple A-Site Cation Mixing in 2D Perovskite-Inspired Antimony Halide Absorbers for Efficient Indoor Photovoltaics

Antimony-based perovskite-inspired materials (PIMs) are solution-processable halide absorbers with interesting optoelectronic properties, low toxicity, and good intrinsic stability. Their bandgaps around 2 eV make them particularly suited for indoor photovoltaics (IPVs). Yet, so far only the fully inorganic Cs3Sb2ClxI9−x composition has been employed as a light-harvesting layer in IPVs. Herein, th

Functional muscle synergies to support the knee against moment specific loads while weight bearing

Objective: Externally applied abduction and rotational loads are major contributors to the knee joint injury mechanism; yet, how muscles work together to stabilize the knee against these loads remains unclear. Our study sought to evaluate lower limb functional muscle synergies in healthy young adults such that muscle activation can be directly related to internal knee joint moments. Methods: Conca

A time-efficient multi-deviant paradigm to determine the effects of gap duration on the mismatch negativity

The insertion of a silent period (or gap) in a frequently occurring standard stimulus elicits a negative-going event-related potential (ERP), called the Deviant-Related Negativity (DRN). This is often studied using a single-deviant paradigm. To study the effects of gaps with multiple durations, a different sequence would be required for each gap. A more time-efficient multi-deviant paradigm has be

Differences in EMG–moment relationships between ACL-injured and uninjured adults during a weight-bearing multidirectional force control task

Anterior cruciate ligament injury (ACLi) reduces mechanical knee joint stability. Differences in muscle activation patterns are commonly identified between ACLi individuals and uninjured controls (CON); however, how and which of these differences are adaptations to protect the knee or adversely increase risk of joint instability remain unclear. Since the neuromuscular system integrates activity of

Influence of electrode type on neuromuscular activation patterns during walking in healthy subjects

The role of muscle activation in both pathological and spastic populations is of interest for understanding central nervous system function. Muscle activation patterns may provide insight into pathological changes compared to healthy controls. To gain a better understanding of surgical interventions, gait muscle activation patterns are studied before and after surgery. Previous studies using surfa

Methodological concerns using intra-cortical pins to measure tibiofemoral kinematics

The complexity of human tibiofemoral joint motion is now better understood with the advancement of new methodologies to measure tibiofemoral kinematics in vivo. Marker clusters anchored to stainless steel bone pins inserted directly into the femur and tibia provide the most sensitive and accurate means for directly measuring skeletal tibiofemoral joint motion. Despite its invasiveness, this techni

Efficiency improvement for perovskite-inspired Cs3Sb2I9solar cells using P3HT as the hole transport material

In this work, we introduce P3HT (poly(3-hexylthiophene-2,5-diyl)) as an efficient hole transport material (HTM) for lead-free Cs3Sb2I9perovskite-inspired solar cells. The P3HT doubles the power conversion efficiency (PCE) of the solar cells (PCE = 2.5% for the champion device) by improving all of the figures of merit: the fill factor, open-circuit voltage, and the short-circuit current. The maximu

Search for Weak Side Branches in the Electromagnetic Decay Paths of the 6526-keV 10+ Isomer in 54Fe

High-spin nuclear isomers in N≈Z nuclei between doubly magic 40Ca and 56Ni provide an excellent testing ground for the nuclear shell model and questions related to isospin symmetry breaking in the vicinity of the proton drip line. The purpose of the present study is to investigate the possibility of weak electromagnetic decay branches along the decay paths of the 6526-keV 10+ isomer in 54Fe. The i

Manganese Doping Promotes the Synthesis of Bismuth-based Perovskite Nanocrystals While Tuning Their Band Structures

The doping of halide perovskite nanocrystals (NCs) with manganese cations (Mn2+) has recently enabled enhanced stability, novel optical properties, and modulated charge carrier dynamics of the NCs host. However, the influence of Mn doping on the synthetic routes and the band structures of the host has not yet been elucidated. Herein, it is demonstrated that Mn doping promotes a facile, safe, and l

A novel approach for brake emission estimation based on traffic microsimulation, vehicle system dynamics, and machine learning modeling

Brake wear is known as the primary source of traffic-related non-exhaust particle generation. Its generation rate is influenced by parameters at different levels: subsystem (type of brakes, pads, materials, etc.), system (vehicles' dynamics, driving style etc.) and suprasystem (road geometries, traffic parameters, etc.). At the subsystem level, we proposed a neural network brake emission modeling,

Implementing the dual approaches for solving LWE

Many of the finalists selected for the NIST post-quantum cryptography project are lattice-based and rely on a Learning With Errors problem (LWE). To solve such a problem, it is possible to implement a primal attack or a dual attack. In this context, Guo and Johansson as well as the MATZOV center have both proposed an improved dual attack against several NIST lattice candidates. The goal of this t

The impact of honeybee density and apiary proximity on bumblebee foraging behavior depends on landscape-level forage availability

Bin är viktiga för att de flesta vilda blommor och många av våra grödor ska kunna föröka sig och därmed för viktiga för ett välfungerande ekosystem! Men på grund av att människan har förändrat binas naturliga miljöer så är de vilda bina hotade. För att kompensera för de minskande populationerna av vilda bina och på grund av våra storskaliga odlingar så har mängden tama honungsbin ökat för att pollThe decline of pollinators has led to an upswing of managed honeybees and the competitive impact this has on wild pollinators has growing evidence. The conservation of wild pollinators is crucial to maintaining plant diversity in natural ecosystems and ensuring global food security. In order to fully understand the impact deployment of honeybees have on other wild bees there is a need for studies

Host and graft glial composition in a stem cell transplantation model of Parkinson’s disease

Parkinson’s disease (PD) is the second most common neurodegenerative disease, and it is known for the recognisable motor symptoms. The cause of the disease is the loss of a specific cell type in the brain, called dopaminergic (DA) neurons. Significant steps towards stem cell replacement therapy of DA neurons have been made in the last few decades. Despite that, one aspect has been quite overlooked
