Emergence of a Hexagonal Fe2S2 Single Layer Without a Bulk Counterpart via Phase Transformation

open access: yesAdvanced Functional Materials, EarlyView.
Upon annealing, single‐layer Mackinawite iron sulfide transforms into a previously unknown hexagonal Fe2S2${\rm Fe}_2{\rm S}_2$ phase with β$\beta$‐CuI structure. STM, LEED, and first‐principles calculations identify the structure and show that electronic correlations and magnetic order are important for its stability.

APTES‐Mediated Ti‐Squarate MOF/n‐GaN Nanowire Photoanodes for Efficient Photoelectrochemical Water Splitting

open access: yesAdvanced Functional Materials, EarlyView.
The APTES linker establishes a permanent interfacial dipole, reducing the work function of n‐GaN from 3.55 to 3.29 eV. This strengthens the built‐in electric field, significantly accelerating hole extraction to drive the oxygen evolution reaction (OER). Ultimately, this tailored charge‐separation architecture achieves a remarkable 4.78‐fold enhancement

Does Daily Sunshine make you Happy? Subjective Measures of Well-being and the Weather [PDF]

open access: yes, 2016
This paper examines to what extent individual measures of well-being are correlated with daily weather patterns in the United Kingdom. Merging daily weather data with data from the British Household Panel Survey (BHPS) allows us to test whether measures ...

Microfluidic Architecting of Patchy MXene Core‐Shell Particles for Ultralow‐Loading Photothermal Shape‐Memory Actuation

open access: yesAdvanced Functional Materials, EarlyView.
Spatially distributing Ti3C2Tx nanosheets into core‐shell architecture, rather than as directly dispersed flakes, mitigates aggregation and enhances photon harvesting. When the Ti3C2Tx core‐shell particles are incorporated into a shape‐memory polymer matrix at an ultralow loading of 0.0024 wt%, the improved photothermal conversion translates into ...

Simulation of hourly cloud cover, sunshine ratio, and solar radiation throughout a year using satatistical quantities derived from observed weather data

open access: yesSimulation of hourly cloud cover, sunshine ratio, and solar radiation throughout a year using satatistical quantities derived from observed weather data, 1986
Using a statistical method, the relation between the hourly solar radiation TH and the hourly cloud cover CC, sunshine ratio SH, and rain and snow index RS was studied. On the basis of the results, a formula for predicting the value of TH as a function of CC, SH, and RS was drawn out.

Reliability-Oriented Design and Sizing of a Standalone Solar PV-Battery Chick Brooding System under the Cool Highland Climate of Mbeya, Tanzania

open access: yesElectrical Engineering and Energy
Though the heating need often matches poor or very variable energy access, reliable chick brooding in cold mountain regions calls for constant heat during the first weeks after hatching.

Re-framing community disaster resilience: from a systems perspective: Sunshine Coast case study report

open access: yes, 2014
There is a shared need to measure a community's resilience to disaster from planning and preparedness to response, recovery and reflection of `lessons learnt'. To this end, the Australian Government Attorney General's office funded the development of the
