Phase‐Pure and Size‐Tunable Tin Halide Perovskite Quantum Dots

open access: yesAdvanced Materials, EarlyView.
A trioctylphosphine oxide modulated protocol allows for the synthesis and study of the optical properties of a broad library of tin halide perovskite quantum dots across multiple A‐ and X‐site compositions with precise size tuning while eliminating unwanted 2D phases.

Elevation-Dependent Glacier Albedo Modelling Using Machine Learning and a Multi-Algorithm Satellite Approach in Svalbard

open access: yesRemote Sensing
Glacier surface albedo controls solar energy absorption and Arctic mass balance, yet comprehensive modelling approaches remain limited. This study develops and validates multiple modelling frameworks for glacier albedo prediction using automatic weather ...

A fifty year record of winter glacier melt events in southern Chile, 38°–42°S [PDF]

open access: yes, 2012
Little is known about the frequency and potential mass balance impact of winter glacier melt events. In this study, daily atmospheric temperature soundings from the Puerto Montt radiosonde (41.43°S) are used to reconstruct winter melting events at the ...

Modelling Dynamics of Valley Glaciers

open access: yes, 2012
Ever since the Paleoproterozoic snowball Earth era, ca. 2.4 billion years ago (e.g. Hoffman & Schrag, 2000; Kirschvink, 1992), and beyond, the landscape of the planet Earth has been shaped up by the tremendous amount of scouring due to the repeated waxing and waning of ice masses.

3D Printed Omniphobic Slippery Liquid Infused Porous Surfaces for Low Surface Tension Repellency

open access: yesAdvanced Materials Technologies, EarlyView.
A 3D printing strategy fabricates omniphobic slippery liquid‐infused porous structures with lubricant reservoirs and interconnected microchannels. A post‐printing surface treatment modifies the porous surface to ensure compatibility with the infused fluorinated lubricant.

Multivalent Glycopolymer Design Unlocks Antimicrobial Activity of 2‐Deoxyglucose

open access: yesAngewandte Chemie, EarlyView.
New approaches to combat antimicrobial‐resistant pathogens are needed. Here, scaffolding a nonmetabolizable sugar (2DG) on a polymer backbone is shown to significantly improve its antimicrobial activity. ABSTRACT With the increasing prevalence of multidrug‐resistant (MDR) pathogens, last‐line therapeutics such as cyclic peptides are insufficient ...

Hydraulic impacts of glacier advance over a sediment bed [PDF]

open access: yes, 2006
A sedimentary sequence of till overlying a gravel aquifer was instrumented with water-pressure transducers prior to a small, anticipated surge of the margin of the glacier Breiðamerkurjökull in Iceland.

An Artificial Antibody‐Based Toolbox Accelerates Validation of Hidden Microproteins Encoded by the Dark Genome

open access: yesAdvanced Science, EarlyView.
Microproteins are hidden treasures encoded by the “dark proteome” but remain largely underexplored due to the lack of highly efficient tools. We developed a molecularly imprinted polymers (MIPs)‐based toolbox (CLAIMID) to achieve accelerated and ultrasensitive microproteins validation at multiple biological scales (single living cells, cell populations,

On non-dimensional forms of basal sliding laws and flow laws for ice-sheet and glacier modelling

open access: yesJournal of Glaciology
Ice sheets and glaciers flow through basal sliding and internal deformation, each governed by physical laws commonly expressed as power-law relations. These formulations include coefficients—the sliding coefficient and rate factor—whose values and units ...

Climatic control on the peak discharge of glacier outburst floods

open access: yes, 2007
Lakes impounded by natural ice dams occur in many glacier regions. Their sudden emptying along subglacial paths can unleash similar to 1 km(3) of floodwater, but predicting the peak discharge of these subglacial outburst floods ('jokulhlaups') is ...
