PPO was first electrospun into a fibrous membrane, then brominated and
reacted with NaN三 to generate the azido-terminated EPFMs. A PNIPAAm was
synthesized and grafted onto the azido-terminated EPFMs. The 苹果平板roughness of PPO fibers was increased due to the presence of PNIPAAm
grafts, such that the thermoresponse of the static water contact angle
(SWCA) of PNIPAAm-grafted EPFMs between 二五 and 四5 °C was significantly
greater than that of the same PNIPAAm grafted on a flat 苹果平板. 塔基ng

摘要

Precision laser spectroscopy of cold and trapped molecular ions is a
powerful tool in fundamental physics—used, for example, in determining
fundamental constants, testing for their possible variation in the
laboratory, and searching for a possible electric dipole moment of the
electron. However, the absence of cycling transitions in molecules poses
a challenge for direct laser cooling of the ions, and for controlling,
and detecting their quantum states. Previously used state-detection
techniques based on photo-dissociation or chemical reaction are
destructive and therefore inefficient, restricting the achievable
resolution in laser spectroscopy. Here, we experimentally demonstrate
non-destructive detection of the quantum state of a single trapped
molecular ion through its strong Coulomb coupling to a well controlled,
co-trapped atomic ion. An algorithm based on a state-dependent optical
dipole force changes the internal state of the atom according to the
internal state of the molecule. We show that individual quantum states
in the molecular ion can be distinguished by the strength of their
coupling to the optical dipole force. We also observe quantum jumps
(induced by black-body radiation) between rotational states of a single
molecular ion. Using the detuning dependence of the state-detection
signal, we implement a variant of quantum logic spectroscopy of a
molecular resonance. Our state-detection technique is relevant to a wide
range of molecular ions, and could be applied to state-controlled
quantum chemistry and to spectroscopic investigations of molecules that
serve as probes for interstellar clouds.

IKVM at Deltix Lab, Inc.

At my company we are still amazed to see large part of our Java system
successfully running on .NET platform thanks to IKVM.

We plan to use IKVM heavily in our technology stack. Our company
develops a product for financial data integration and analytics. IKVM
will be used to interface our Java-based server with C# based front
end. IKVM allows to reuse Java code in .NET modules. For instance, the
same ActiveMQ messaging code written on Java now also brings data to our
C# application. — Andy Malakov, System Architect, SCEA

IKVM at eTrading and Analytics Group at HSBC

eTrading and Analytics Group at HSBC provides real-time pricing and
algorithmic strategies for a variety of financial markets.

We are very happy with IKVM. It enables us to develop our core libraries
in Java and compile for use in .NET. The IKVM team is very responsive
and knowledgeable about the issues we were facing.

Some challenges we faced were:

  • working with the classpath
  • downcasting generics in java to using a base object in .NET
  • integrating 3rd party C++ libraries which use JNI

IKVM provides a number of flexible options for us to define the
classpath.

Generics would help us enforce the contract between the library and the
.NET developer. In practice, we write thin .NET UI applications so this
is manageable.

Integrating with in-house quantitative analytic libraries that are
exposed through JNI worked effortlessly. However, we hit a roadblock
trying to use Reuters sass3j.dll. We suspect there may be some
differences in the event models.

All in all, this is an excellent tool that offers us the flexibility to
focus on developing domain specific solutions without worrying about
porting issues. IKVM solves that. — Shamus Neville

IKVM for JSTM

JSTM is an open source Java library for distributed object replication.
IKVM allowed us to replicate objects between java and dotnet
applications very easily. The whole Java library is compiled to a dll,
and communication between the Java and .NET processes is done over TCP
or HTTP using the same Java code.

This project makes heavy use of the Java IO and collections classes, and
we did not have to modify the Java version to get the same features and
similar performance on the .NET framework. There seem to be bugs left in
the new Java 5 collections and for the formatting of dates, but the IO
stack is robust. IKVM is way beyond our previous solution based on J#,
and it allows lots of cool scenarios. — Cyprien NOEL,

关于举行南开东军政大学学王晓琳助教学术报告会的通报,关于实行广东农林科技大学Jem。摘要

The non-equilibrium control of emergent phenomena in solids is an
important research frontier, encompassing effects such as the optical
enhancement of superconductivity. Nonlinear excitation of certain
phonons in bilayer copper oxides was recently shown to induce
superconducting-like optical properties at temperatures far greater than
the superconducting transition temperature, Tc (refs 4, 5, 6). This
effect was accompanied by the disruption of competing
charge-density-wave correlations, which explained some but not all of
the experimental results. Here we report a similar phenomenon in a very
different compound, K3C60. By exciting metallic K3C60 with mid-infrared
optical pulses, we induce a large increase in carrier mobility,
accompanied by the opening of a gap in the optical conductivity. These
same signatures are observed at equilibrium when cooling metallic K3C60
below Tc (20 kelvin). Although optical techniques alone cannot
unequivocally identify non-equilibrium high-temperature
superconductivity, we propose this as a possible explanation of our
results.

IKVM at Chordiant Software

Chordiant software and solutions help major brand enterprises around the
world deliver the best possible customer experience.

Our product suite consists of J2EE applications as well as Windows
desktop systems. As an IKVM customer, Chordiant was able to consolidate
our dedicated C++ engine with our Java code base. This effectively
enabled us to cut development time on one specific product in half.

Having used IKVM for over a year, we have found IKVM to work reliably
and offer production quality operation. The one time where we did run
into some specific problem, the open source nature of IKVM allowed us to
quickly track down the bug and verify the cause of the problem. We had a
fix for the problem the very same day.

In short, at Chordiant we like IKVM a lot. — Otto Perdeck, development

IKVM at eInstruction

At eInstruction, we provide classroom response systems that include
custom hardware for gathering responses from students. Our main
application was originally written in J++, including some pure Java
libraries. This past year we needed to port to .NET. We made some
attempts with J#, but ran into some limitations that IKVM does not
suffer from. IKVM has been a key part of the success of our port, and we
continue to use it to cross-compile our Java hardware API to .NET. IKVM
is stable, performs great and Jeroen’s support for the few esoteric
cases we’ve run into has been fantastic. — Chris Morris, eInstruction.

IKVM at WL | Delft Hydraulics

WL | Delft Hydraulics is an independent research institute and
specialist consultancy based in the Netherlands. One of our tasks is to
make world leading software in watermodelling. I work on the integration
of different models. Some models may concern water movement, other
models may provide information on water quality. All these models have
to work together and exchange information. My main concern is the data
communication between these models.

At this moment we’re working on making our software OpenMI compliant.
OpenMI is a European standard for inter model communication. The
standard defines how, when and what information is exchanged between
models.

In this part of our software different programming languages are used.
The calculations in the models are done with FORTRAN 90. The
communication between models is layered. The interprocess communication
is implemented in Java. The OpenMI implementation, which takes care of
the communication on model level is written in C#.

To make the connection between these communication layers we are using
IKVM. A colleague informed me about the IKVM software. I read the
documentation on the website, downloaded and started combining it with
our software. It was an instant success. It solved a lot of our
multi-language problems. We haven’t stopped using it.

I have run into two problems. After updating our Java version to version
5.0, it didn’t compile. It was easily fixed with assistance of the IKVM
main developers. The second problem is trickier. In one of our test
cases the Java code fails in the first call. This can be fixed by
declaring a Java object in the main routine of the program. It can have
something to do with threading in combination with initialization of
static variables in the Java code. We have not figured out the problem
yet. A drawback of IKVM is in this case that you can not debug the Java
code to track down the problem.

IKVM saves us a lot of time setting up the connection between Java and
C#. It can be a drawback when you have to debug the underlying Java
code. It’s amazing how this software bridges the gap between the Java
and C# world. — David Levelt, Software Engineer WL | Delft Hydraulics

摘要

Although the oxidation of water is efficiently catalysed by the
oxygen-evolving complex in photosystem II (refs 1 and 2), it remains one
of the main bottlenecks when aiming for synthetic chemical fuel
production powered by sunlight or electricity. Consequently, the
development of active and stable water oxidation catalysts is crucial,
with heterogeneous systems considered more suitable for practical use
and their homogeneous counterparts more suitable for targeted,
molecular-level design guided by mechanistic understanding. Research
into the mechanism of water oxidation has resulted in a range of
synthetic molecular catalysts, yet there remains much interest in
systems that use abundant, inexpensive and environmentally benign metals
such as iron (the most abundant transition metal in the Earth’s crust
and found in natural and synthetic oxidation catalysts). Water oxidation
catalysts based on mononuclear iron complexes have been explored, but
they often deactivate rapidly and exhibit relatively low activities.
Here we report a pentanuclear iron complex that efficiently and robustly
catalyses water oxidation with a turnover frequency of 1,900 per second,
which is about three orders of magnitude larger than that of other
iron-based catalysts. Electrochemical analysis confirms the redox
flexibility of the system, characterized by six different oxidation
states between FeII5 and FeIII5; the FeIII5 state is active for
oxidizing water. Quantum chemistry calculations indicate that the
presence of adjacent active sites facilitates O–O bond formation with a
reaction barrier of less than ten kilocalories per mole. Although the
need for a high overpotential and the inability to operate in water-rich
solutions limit the practicality of the present system, our findings
clearly indicate that efficient water oxidation catalysts based on iron
complexes can be created by ensuring that the system has redox
flexibility and contains adjacent water-activation sites.

摘要

The ocean has absorbed 41 per cent of all anthropogenic carbon emitted
as a result of fossil fuel burning and cement manufacture. The magnitude
and the large-scale distribution of the ocean carbon sink is well
quantified for recent decades. In contrast, temporal changes in the
oceanic carbon sink remain poorly understood. It has proved difficult to
distinguish between air-to-sea carbon flux trends that are due to
anthropogenic climate change and those due to internal climate
variability. Here we use a modelling approach that allows for this
separation, revealing how the ocean carbon sink may be expected to
change throughout this century in different oceanic regions. Our
findings suggest that, owing to large internal climate variability, it
is unlikely that changes in the rate of anthropogenic carbon uptake can
be directly observed in most oceanic regions at present, but that this
may become possible between 2020 and 2050 in some regions.

摘要

Third-party punishment (TPP), in which unaffected observers punish
selfishness, promotes cooperation by deterring defection. But why should
individuals choose to bear the costs of punishing? We present a game
theoretic model of TPP as a costly signal of trustworthiness. Our model
is based on individual differences in the costs and/or benefits of being
trustworthy. We argue that individuals for whom trustworthiness is
payoff-maximizing will find TPP to be less net costly (for example,
because mechanisms that incentivize some individuals to be trustworthy
also create benefits for deterring selfishness via TPP). We show that
because of this relationship, it can be advantageous for individuals to
punish selfishness in order to signal that they are not selfish
themselves. We then empirically validate our model using economic game
experiments. We show that TPP is indeed a signal of trustworthiness:
third-party punishers are trusted more, and actually behave in a more
trustworthy way, than non-punishers. Furthermore, as predicted by our
model, introducing a more informative signal—the opportunity to help
directly—attenuates these signalling effects. When potential punishers
have the chance to help, they are less likely to punish, and punishment
is perceived as, and actually is, a weaker signal of trustworthiness.
Costly helping, in contrast, is a strong and highly used signal even
when TPP is also possible. Together, our model and experiments provide a
formal reputational account of TPP, and demonstrate how the costs of
punishing may be recouped by the long-run benefits of signalling one’s
trustworthiness.

Abstract: Nanofiltration (NF) membrane, firstly named as loose Reverse
osmosis (RO) or dense Ultrafiltration (UF) membrane, has two remarkable
features: one is the molecular weight cut-offs (MWCO) ranges from 200 to
2000Da, and the other is the salt rejection depends on the ion valence
and concentration. Several models for NF processes have been proposed,
such as the pore model based on the sieving effect, the charge model
based on the electrostatic effect, the electrostatic steric-hindrance
(ES) model, and the Donnan steric pore model (DSPM) have been proposed,
which play an important role in understanding the separation mechanism
and promoting the application of NF. Afterward, almost all of the RO
membrane manufacturers have produced a series of NF membranes for the
purification and advanced treatment of water. However, the performances
of these NF membranes with features of loose RO membranes cannot be
predicted by commercial RO simulation software. It leads to a long
period of previous experiments and scale-up process, which severely
restricts the large scale standardization applications of NF. In regard
to these problems, we proposed a simple simulation model for the
separation performance of mixed salts solution across NF membranes to
promote the application of NF during the water treatment in the light of
the competitive effect among co-ions and regulation effect among
counter-ions. Both two effects can be determined by some specific
experiments. And then based on the in-depth experimental studies on
rejection performance and the attendant electrokinetic properties, some
researchers have found that the performance of NF membranes cannot be
predicted completely by merely considering the sieving and electrostatic
effect, but some drawbacks still exist in the analysis of electrokinetic
properties. The further studies have contributed to a deeper
understanding on the particular effect caused by the nano-scale pore
size and charge features caused by the complicated interaction in
solution. Moreover, the dielectric effect in the transport process of
ions through NF membranes has been addressed and quantitatively
analyzed. Recent studies have been paid much attention on the new
generation of NF membranes improved by various nanostructured materials.
We also made some try to develop some novel thin-film nano-composite NF
membranes derived from the dual layer (PES/PVDF) hollow fiber UF
membranes.

Abstract: Polyvinylidene fluoride (PVDF) hollow fiber (HF)
Microfiltration (MF) membranes were firstly prepared via thermally
induced phase-separation (TIPS) method, where diphenyl carbonate (DPC)
and diphenyl ketone (DPK) were used as primary diluents. The liquid –
liquid phase-separation phenomena were found and the monotectic points
of PVDF/DPC and PVDF/DPK systems appeared at PVDF concentration
approximately 30 and 56%(wt), respectively. The effects of polymer
concentration and quenching temperature on the pore structure, porosity
and tensile strength of the membranes were also investigated. Secondly a
novel HF PVDF based ultrafiltration (UF) membrane was prepared by
forming a thick poly(sulfobetaine) (PSB) layer on the hollow fiber PVDF
MF membrane. The PVDF based polySB UF membrane has sieving effects with
the MWCO of 5.2 µm and 85~105 kDa, respectively, which contributed to
the greatly improved hydrophilicity, membrane strength and thermal
property. The another way to prepare a HF PVDF based UF membrane was
forming a thick polyethersulfone (PES) outer layer by using the
non-solvent induced phase separation (NIPS) method. Thirdly
Nanoparticles (NPs) reinforced thin-film composite (TFC) membranes
containing a range of 50~200 nm nanoparticles [MWCNTs, GOs, LTA
zeolites] in a polypiperazine-amide (PA) thin film layer were
synthesized via sequential interfacial polymerization on PES/PVDF hollow
fiber substrates. The hydrophilization process of the NPs was conducted
to ensure the homogenous dispersion in the aqueous phase containing
piperazine prior to the interfacial reaction, and their morphologies in
the PA layer were confirmed by FT-IR spectroscopy, SEM, EDX, XPS, and
TEM. For all the NPs reinforced TFC membranes, the water flux increased
significantly. The separation performances of the monovalent and
divalent ions of NaCl/Na2SO4 solutions were conducted. Finally a novel
thin film nanocomposite (TFN) hollow fiber membrane was fabricated
comprising the sulfobetaine polymer functionalized multiwalled carbon
nanotubes (ZCNT). The TFN(ZCNT) hollow fiber membrane had much narrower
pore sizes than TFN(CNT) hollow fiber membranes, which was due to the
grafting PSB layer at the end of the open-mouth-ended CNTs. By
increasing the chain length of PSB, the TFN(ZCNT) hollow fiber membrane
showed simultaneously improved water permeability and separation
capacity of dextrans and electrolytes.
