Recent Charity Donations

Over the years Linkam has supported many of our staff who have taken part in sponsored events. Cycling, running, hiking, swimming their way to raising money for local and national charities.

This year we thought we would do things a little differently, giving all our staff the opportunity to nominate their favourite charity to make sure the charities chosen are close to the hearts of the whole Linkam team. With the results in we have chosen to support 5 different charities with a mix of local and national charities.

The first charity we have chosen to support is Cancer Research. With the population prone to a high risk of getting cancer in their lifetimes, Cancer Research is a vital charity and by supporting this charity, we will be contributing to pivotal scientific research.

The second charity is Princess Alice Hospice; due to the amazing support it offers for end of life care with a variety of support and services.

The third charity we will be donating to is Home-start Epsom, Ewell & Banstead, for the exceptional support provided to those who are struggling with mental or physical health, isolation, or everyday family life.

The final 2 charities we have chose to donate to are Alzheimer’s Research UK and MND Association. Motor neurone disease is recorded to affect around two in every 100,000 people, and by supporting MND Association we can make an impact on the research being conducted on this rare condition.

Alzheimer’s disease affects around 1 in 10 people over 65 and currently 1 in 20 people from the age of 40. The research conducted by this charity is vital in combatting and understanding this disease. Supporting this charity is essential in allowing the growth and level of research provided by the charity.

At Linkam, we are excited to be able to support and donate to all of the above charities, and if you would like to find out more about what they do, we have included the links below:

Photovoltaics (PV) research at the Australian National University (ANU) is at the global cutting edge, spanning the entire spectrum of solar electricity technologies - from solar forecasting, to fabricating high-efficiency PV cells, to integrating renewables with storage capacity into the grid. Dr Hieu Nguyen received his PhD (PV) from the ANU under the supervision of Prof Daniel Macdonald in 2016. Since then, he has been a research fellow and lecturer at the same university.

The central idea of his research is to promote and advance the field of luminescence spectroscopy and imaging through knowledge and scientific discoveries, and technique inventions. His team, as a sub-group of the PV group at the ANU, explore fundamental properties of light emitted from photovoltaic materials and devices under various conditions. They work to uncover the relationship between the emitted light and the important properties of the materials and devices, including optical, electrical, chemical, and structural properties. By exploiting these photons, the team also develop novel Raman/luminescence-based characterisation techniques with applications to renewable energy and material science.

In their labs, they integrate the Linkam THMS600 with a confocal Horiba Raman/luminescence spectrometer and a confocal time-resolved photoluminescence system. These tools allow them to probe optoelectronic properties of numerous photovoltaic materials spanning crystalline silicon, amorphous silicon, SiNx, perovskites, transition-metal dichalcogenides (TMDs), etc. at both material and device levels. The team have made numerous original and significant contributions to fundamental understandings of interactions between light and materials/defects in the PV field.

Professor Oleg Lavrentovich is world renowned for his research work on liquid crystals. He is a Trustees Research Professor at the Kent State University as well at the editor of the Liquid Crystal Reviews journal. Much of his research investigates their practical application. For example, his research group have previously established how to cloak electrodes by using liquid crystals to bend the light around them. They have even researched how to use them as mediums to carry particles such as bacteria. 

Some of their more recent work demonstrated how electric fields can trigger unique structural response in nematic liquid crystals. This in turn can propagate solitary waves that are trapped in all three spatial dimensions. The group used the LTS350* to control the temperature around the sample. Their work demonstrated the rich dynamic behaviour of the liquid crystal system and the ease of control, which paves way for further study. 

The Lavrentovich Research Group are further planning SAXS/WAXS experiments with their CSS450 rheological system and sheared liquid crystals. We look forward to seeing more work from them soon. 

 

*The LTS350 has been superseded by the LTS420 offering a large temperature range and better temperature control to 0.01°C.

Dr. Wing Chung Tsoi is a senior research officer at Swansea University, having joined in 2014. His research group focuses on advanced characterisation techniques to further understand the structure-property-performance relationship of photovoltaic cells, with the aim to improve device stability and power conversion efficiency. Dr Tsoi’s group are also working on new applications of organic/perovskite photovoltaic cells, including for indoor light harvesting, semi-transparent solar cells and solar cells for space applications. 

The group have used a Linkam RH95 humidity system alongside the THMS600-H to conduct in-situ Raman Spectroscopy to further understand the degradation kinetics of perovskite photovoltaic cells [1]. Furthermore, they are using a Linkam LTS420E-PB4 to measure Raman spectroscopy and local photocurrent at the same device region, which provide direct correlation between degradation and the optoelectronic properties. [2] They are also using the Linkam LTS420E-PB4 to do extreme thermal cycling on organic solar cells to study their feasibility for space applications. [3]

Dr Tsoi’s group particularly specialise in advanced Raman techniques, and stability characterisation. Their aim to improve the function of perovskite photovoltaic materials could have great benefits for the future development of low cost, high efficiency solar cells.

Dr. Maths Karlsson is one of the research group leaders in the Division of Energy and Materials at the Department of Chemistry and Chemical Engineering at Chalmers University of Technology since 2017. His research group focuses on investigating key fundamental properties of functional materials, mostly energy relevant oxides.

Their on-going projects involve different fields, such as materials for hydrogen storage, ionic conductors for solid oxide fuel cells, inorganic luminescent oxides (phosphors) for solid state white lighting devices, and so on. The major objective is to understand the mechanistic aspects of dynamical excitations, such as vibrations and diffusion, in relation to defects on the atomic length scale, and to correlate those microscopic properties to the functional macroscopic properties of the materials.

They use the Linkam THMS600, combined with a commercial Raman spectrometer and a home-made optical setup for performing different spectroscopic experiments, and synchrotron facilities for time-resolved experiments. These temperature-controlled experiments provide versatile means to probe static and dynamic states of the materials including crystal structure, vibrational modes and atom diffusion, and electronic structure. Their research findings will benefit the development of new energy materials for future “green” technologies, such as high-power light emitting diodes coated with single-phase phosphors of multi-colour light emissions sustaining high energy efficiency up to very high temperatures.

Dr Denis Cumming is a lecturer in the Department of Chemical and Biological Engineering at the University of Sheffield. He joined the university in 2010 after gaining a PhD from Imperial College on his work on solid oxide fuel cells (SOFCs). 

Building on his work on SOFCs, his main research interests lie in developing stable nanostructured materials for improved high temperature electrochemical electrodes and catalysts. His group particularly focus on several key areas including high temperature in-situ spectroscopic and chemical characterisation, as well as carbon measurement and control at high temperature. They are using the Linkam TS1500EV stage to conduct their high temperature, operando infrared characterisation studies.

The future application of such work is immense. It could help lead to the improvement of fuel cells and electrolysers, electrochemical sensors, gas separators and heterogeneous catalysis. We look forward to seeing more of his work in the future.

Charles Cockell is a Professor of Astrobiology at the University of Edinburgh. 

The UKCA was established in November 2011 and formally opened at the National Museum of Scotland in April 2013. Their core academic interest is the study of life in extreme environments and its application to understanding the habitability of planets. The UKCA is an international partner with the NASA Astrobiology Institute. Since its inception they have developed a range of initiatives, including the development of the world's first underground astrobiology laboratory which it uses for planetary analog research. It has developed research that has spanned across the study of life in extremes and the habitability of extraterrestrial environments. 

Some of the UKCA’s current projects include: the study of the habitability of icy moon oceans, the colonisation of rocks and the way in which communities develop in rocky planetary crust and the response of microorganisms to multiple extremes.

Professor Charles Cockell and his group are currently using the THMS600 stage to simulate the subsurface of the icy moons Europa and Enceladus. In particular it is used to study habitable microenvironments within ice, the phase behaviour of various brines, and how physiochemical parameters related to habitability change as fluids freeze. They also plan to use the THMS350V to understand the surface of these icy moons and how potential biosignatures may be transported, deposited, and preserved during eruption from cryovolcanic plumes.

Dr Sheng Qi is a reader in Pharmaceutics at the University of East Anglia, having joined in 2007. Her group having been working closely with leading pharmaceutical and excipient companies to further research on pharmaceutical processing and formulation development. 

Their current research interests include formulation development manufactured via hot melt extrusion/injection moulding, FDM 3D printing, electrohydrodynamic processes, drug-polymer/lipid miscibility and solubility and polymer facilitated drug solubilisation in biological fluids to name a few. 

Dr Qi and Dr Alhijjaj are using the Linkam MDS600 alongside TASC (Thermal Analysis by Structural Characterisation) as a rapid screening method for drug-polymer miscibility for formulation development. They also used TASC to look at the maximum percentage of drug that could be solubilised within particular polymers. Their results allowed them to select for the most suitable polymeric candidates for formulations. Their methodology has so far proved to be comparable and faster than current screening protocols.
