Pyridine‐Isomerism‐Driven Spin Engineering at a COP‐Fe3O4 Interface for High‐Performance Oxygen Reduction Electrocatalysis

open access: yesAdvanced Energy Materials, EarlyView.
Strategically adjusting the pyridine nitrogen position in the polymer matrix (pyridine isomerism) intensifies its interaction with embedded Fe3O4 nanocrystals. This enhanced interaction induces a spin‐state transition in Fe from low‐spin to intermediate‐spin, accompanied by refined d‐orbital properties.

Built‐In Electric Field Regulated Electron Transport Channels of FeP Supported Os for Ampere‐Level Seawater Electrolysis

open access: yesAdvanced Energy Materials, EarlyView.
This work presents an Os/FeP heterostructure catalyst with EMSI and successfully utilizes the BEF to further modulate electron transfer through Os‐P‐Fe channels, proving an effective approach of developing low‐cost electrocatalysts with remarkable HER activity in ampere‐level seawater electrolysis. ABSTRACT Developing cost‐effective and robust hydrogen

Temperature Sensitivity and Adaptation of Cereal Yields: Empirical Evidence From Italy

open access: yesApplied Economic Perspectives and Policy, EarlyView.
ABSTRACT This paper investigates the evolving temperature sensitivity and climate adaptation of cereal yields in Italy from 1952 to 2023, using province‐level data for maize, common wheat, and durum wheat. Employing panel data econometric methods, we estimate yield responses to heat exposure, changes in sensitivity over time, and adaptation to climate ...

Study of the absorption refrigerating cycle, NH3-H2O coupled with the solar absorption heat transformer, H2O-LiBr by solar data from the City of Oujda (Morocco)

open access: yesRevue des Énergies Renouvelables, 2015
A solar refrigerator is made of a solar collector and a refrigeration system. This paper concerns the study of a two-stage vapour absorption cycle (heat transformer and refrigerating cycle) employing the refrigerant absorbent combinations of H2O-LiBr and

Measuring Nutrition Security Using the Consumer Food Data System Datasets

open access: yesApplied Economic Perspectives and Policy, EarlyView.
ABSTRACT Nutrition security is an emerging concept lacking a consensus definition, conceptualization, or standardized measure. This perspectives manuscript synthesizes findings from two previously published analyses to assess the feasibility of using available measures of key dimensions of nutrition security from two Consumer Food Data System (CFDS ...

Good cop / Bad cop

open access: yes, 2017
Denna uppsats belyser hur förhörsledare väljer förhörsmetod och hur det kan påverka rättssäkerheten. Syftet var att undersöka hur erfarenheten påverkar förhörsledarens val av förhörsmetod samt hur erfarenheten tas tillvara och sprids inom Polisverksamheten. Studien har genomförts i samarbete med Polisen i Malmö.

Why Didn't I Get a Payout? Understanding Farmer Choices, Index Insurance, and Basis Risk

open access: yesApplied Economic Perspectives and Policy, EarlyView.
ABSTRACT Index insurance, while heralded as a potential solution to alleviate poverty and food insecurity among agricultural households, has its own set of challenges, notably basis risk. Basis risk is the discrepancy between the insurance payout and losses incurred, posing a significant deterrent to the adoption of index insurance.

Coping With Production Risk: Effects of Sown Plant Diversity on the Attractiveness of Crop Insurance in Grasslands

open access: yesApplied Economic Perspectives and Policy, EarlyView.
ABSTRACT Increased frequency of extreme weather events, particularly droughts, threatens grassland farming by destabilizing yields and farms' economic viability. We examine, theoretically and through numerical simulations, how sown plant diversity (natural insurance) influences the attractiveness of indemnity and drought index insurance (formal ...
