text: The performance of glaciohydrological models which simulate catchment response
to climate variability depends to a large degree on the data used to force the
models. The forcing data become increasingly important in high-elevation, glacierized
catchments where the interplay between extreme topography, climate, and the cryosphere
is complex. It is challenging to generate a reliable forcing data set that captures
this spatial heterogeneity. In this paper, we analyze the results of a 1 year
field campaign focusing on air temperature and precipitation observations in the
Langtang valley in the Nepalese Himalayas. We use the observed time series to
characterize both temperature lapse rates (LRs) and precipitation gradients (PGs).
We study their spatial and temporal variability, and we attempt to identify possible
controlling factors. We show that very clear LRs exist in the valley and that
there are strong seasonal differences related to the water vapor content in the
atmosphere. Results also show that the LRs are generally shallower than the commonly
used environmental lapse rates. The analysis of the precipitation observations
reveals that there is great variability in precipitation over short horizontal
distances. A uniform valley wide PG cannot be established, and several scale-dependent
mechanisms may explain our observations. We complete our analysis by showing the
impact of the observed LRs and PGs on the outputs of the TOPKAPI-ETH glaciohydrological
model. We conclude that LRs and PGs have a very large impact on the water balance
composition and that short-term monitoring campaigns have the potential to improve
model quality considerably.

text: Himalayan glacier tongues are commonly debris covered and they are an important
source of melt water. However, they remain relatively unstudied because of the
inaccessibility of the terrain and the difficulties in field work caused by the
thick debris mantles. Observations of debris-covered glaciers are therefore scarce
and airborne remote sensing may bridge the gap between scarce field observations
and coarse resolution space-borne remote sensing. In this study we deploy an Unmanned
Aerial Vehicle (UAV) before and after the melt and monsoon season (May and October
2013) over the debris-covered tongue of the Lirung Glacier in Nepal. Based on
stereo-imaging and the structure for motion algorithm we derive highly detailed
ortho-mosaics and digital elevation models (DEMs), which we geometrically correct
using differential GPS observations collected in the field. Based on DEM differencing
and manual feature tracking we derive the mass loss and the surface velocity of
the glacier at a high spatial accuracy. On average, mass loss is limited and the
surface velocity is very small. However, the spatial variability of melt rates
is very high, and ice cliffs and supra-glacial ponds show mass losses that can
be an order of magnitude higher than the average. We suggest that future research
should focus on the interaction between supra-glacial ponds, ice cliffs and englacial
hydrology to further understand the dynamics of debris-covered glaciers. Finally,
we conclude that UAV deployment has large potential in glaciology and it may revolutionize
methods currently applied in studying glacier surface features.

text: 'Switzerland is one of the countries with some of the longest and best glaciological
data sets. Its glaciers and their changes in response to climate have been extensively
investigated, and the number and quality of related studies are notable. However,
a comprehensive review of glacier changes and their impact on the hydrology of
glacierised catchments for Switzerland is missing and we use the opportunity provided
by the EU-FP7 ACQWA project to review the current state of knowledge about past
changes and future projections. We examine the type of models that have been applied
to infer glacier evolution and identify knowledge gaps that should be addressed
in future research in addition to those indicated in previous publications. Common
characteristics in long-term series of projected future glacier runoff are an
initial peak followed by a decline, associated with shifts in seasonality, earlier
melt onset and reduced summer runoff. However, the quantitative predictions are
difficult to compare, as studies differ in terms of model structure, calibration
strategies, input data, temporal and spatial resolution as well as future scenarios
used for impact studies. We identify two sources of uncertainties among those
emerging from recent research, and use simulations over four glaciers to: i) quantify
the importance of the correct extrapolation of air temperature, and ii) point
at the key role played by debris cover in modulating glacier response.'

text: We investigate the performance of five glacier melt models over a multi-decadal
period in order to assess their ability to model future glacier response. The
models range from a simple degree-day model, based solely on air temperature,
to more-sophisticated models, including the full shortwave radiation balance.
In addition to the empirical models, the performance of a physically based energy-balance
(EB) model is examined. The melt models are coupled to an accumulation and a surface
evolution model and applied in a distributed manner to Rhonegletscher, Switzerland,
over the period 1929–2012 at hourly resolution. For calibration, seasonal mass-balance
measurements (2006–12) are used. Decadal ice volume changes for six periods in
the years 1929–2012 serve for model validation. Over the period 2006–12, there
are almost no differences in performance between the models, except for EB, which
is less consistent with observations, likely due to lack of meteorological in
situ data. However, simulations over the long term (1929–2012) reveal that models
which include a separate term for shortwave radiation agree best with the observed
ice volume changes, indicating that their melt relationships are robust in time
and thus suitable for long-term modelling, in contrast to more empirical approaches
that are oversensitive to temperature fluctuations.

text: 'Glaciers in the Andes of Chile seem to be shrinking and possibly loosing
mass, but the number and types of studies conducted, constrained mainly by data
availability, are not sufficient to provide a synopsis of glacier changes for
the past or future or explain in an explicit way causes of the observed changes.
In this paper, we provide a systematic review of changes in glaciers for the entire
country, followed by a discussion of the studies that have provided evidence of
such changes. We identify a missing type of work in distributed, physically-oriented
modelling studies that are needed to bridge the gap between the numerous remote
sensing studies and the specific, point scale works focused on process understanding.
We use an advanced mass balance model applied to one of the best monitored glaciers
in the region to investigate four main research issues that should be addressed
in modelling studies for a sound assessment of glacier changes: 1) the use of
physically-based models of glacier ablation (energy balance models) versus more
empirical models (enhanced temperature index approaches); 2) the importance of
the correct extrapolation of air temperature forcing on glaciers and in high elevation
areas and the large uncertainty in model outputs associated with it; 3) the role
played by snow gravitational redistribution; and 4) the uncertainty associated
with future climate scenarios. We quantify differences in model outputs associated
with each of these choices, and conclude with suggestions for future work directions.'

text: Nature has long inspired scientists with its seemingly unlimited ability to
harness solar energy and to utilize it to drive various physiological processes.
With the help of man-made molecular photoswitches, we now have the potential to
outperform natural systems in many ways, with the ultimate goal of fabricating
multifunctional materials that operate at different light wavelengths. An important
challenge in developing light-controlled artificial molecular machines lies in
attaining a detailed understanding of the photoisomerization-coupled conformational
changes that occur in macromolecules and molecular assemblies. In this issue of
ACS Nano, Bléger, Rabe, and co-workers use force microscopy to provide interesting
insights into the behavior of individual photoresponsive molecules and to identify
contraction, extension, and crawling events accompanying light-induced isomerization.

text: Nanoporous frameworks are polymeric materials built from rigid molecules,
which give rise to their nanoporous structures with applications in gas sorption
and storage, catalysis and others. Conceptually new applications could emerge,
should these beneficial properties be manipulated by external stimuli in a reversible
manner. One approach to render nanoporous frameworks responsive to external signals
would be to immobilize molecular switches within their nanopores. Although the
majority of molecular switches require conformational freedom to isomerize, and
switching in the solid state is prohibited, the nanopores may provide enough room
for the switches to efficiently isomerize. Here we describe two families of nanoporous
materials incorporating the spiropyran molecular switch. These materials exhibit
a variety of interesting properties, including reversible photochromism and acidochromism
under solvent-free conditions, light-controlled capture and release of metal ions,
as well reversible chromism induced by solvation/desolvation.

text: Organizing inorganic nanocrystals into complex architectures is challenging
and typically relies on preexisting templates, such as properly folded DNA or
polypeptide chains. We found that under carefully controlled conditions, cubic
nanocrystals of magnetite self-assemble into arrays of helical superstructures
in a template-free manner with >99% yield. Computer simulations revealed that
the formation of helices is determined by the interplay of van der Waals and magnetic
dipole-dipole interactions, Zeeman coupling, and entropic forces and can be attributed
to spontaneous formation of chiral nanocube clusters. Neighboring helices within
their densely packed ensembles tended to adopt the same handedness in order to
maximize packing, thus revealing a novel mechanism of symmetry breaking and chirality
amplification.

text: In the past few years, spiropyran has emerged as the molecule-of-choice for
the construction of novel dynamic materials. This unique molecular switch undergoes
structural isomerisation in response to a variety of orthogonal stimuli, e.g.
light, temperature, metal ions, redox potential, and mechanical stress. Incorporation
of this switch onto macromolecular supports or inorganic scaffolds allows for
the creation of robust dynamic materials. This review discusses the synthesis,
switching conditions, and use of dynamic materials in which spiropyran has been
attached to the surfaces of polymers, biomacromolecules, inorganic nanoparticles,
as well as solid surfaces. The resulting materials show fascinating properties
whereby the state of the switch intimately affects a multitude of useful properties
of the support. The utility of the spiropyran switch will undoubtedly endow these
materials with far-reaching applications in the near future.

text: A compound combining the features of a molecular rotor and a photoswitch was
synthesized and was shown to exist as three diastereomers, which interconvert
via a reversible cyclic reaction scheme. Each of the three diastereomers was isolated,
and by following the equilibration kinetics, activation barriers for all reactions
were calculated. The results indicate that the properties of molecular switches
depend heavily on their immediate chemical environment. The conclusions are important
in the context of designing new switchable molecules and materials.
