We demonstrated a technology to experimentally investigate plasmon enhanced fluorescence at the sub-nanometer scale, where strong fluorescence quenching occurs. We have experimentally identified optimal gap sizes for maximum plasmon enhanced fluorescence with tunable dielectric spacers.

The OWSD General Assembly and international conference will be held entirely online for the first time in OWSD's 28-year history, allowing as many of OWSD's 7600+ members to participate as possible.

The conference theme is 'Women, science and development', exploring three areas of relevance: 1) the importance of basic sciences for development; 2) the impact of applied sciences on development and 3) including sex and gender as variables in scientific research.


**Keynote speakers include:** 
* Fabiola Gianotti, Director-General of CERN; 
* Bina Agarwal, an internationally celebrated economist specializing in the political economy of gender, poverty and inequality; and 
* Angela Saini, award-winning author of Inferior: How Science Got Women Wrong and the New Research That’s Rewriting the Story, Superior: The Return of Race Science, and other books. 

OWSD members will present their own research in the three themes during poster sessions throughout the conference. In addition, members will also present their own scientific and personal responses to the COVID-19 pandemic. All members will also have the opportunity to take part in a workshop on increasing their visibility and impact as a scientist, with a session on using podcasts for storytelling by Joy Owango and Adelle Onyango of the Training Centre in Communication (TCC Africa), followed by a session on filmmaking for impact by Nicole Leghissa, OWSD video consultant.

The conference will include a handover of the previous OWSD Executive Board to the new members, elected in June-July 2021. On the last day of the conference (19 November), the OWSD Italy Country Network will be launched. **This will be an in-person event in Trieste.** Italian government representatives and donors are invited to attend. The Trieste event will be coordinated with similar in person events being held in OWSD countries throughout the developing world and streamed online. At least 2,000 OWSD members, women scientists from developing countries around the world, are expected to participate online in the General Assembly and conference.

 

**ABOUT THE PROGRAMME**

In order to approach the complex and wide-ranging challenges of the 2030 Agenda for Sustainable Development, societies around the world must access and harness all the talent and experience available to them. The concerns and perceptions of the greatest number of all possible actors and recipients must be considered in order that the most relevant issues and effective solutions are found. Women are considerably underrepresented as researchers in STEM subjects around the globe; according to UNESCO Institute of Statistics (UIS) data, in 2019 the global average percentage of women researchers was still below 30%. Yet women typically have first hand specialist knowledge of the day-to-day challenges diverse individuals face within communities, and can be key informers in the design and development of their solutions. Moreover, since women are most often the providers of informal community support, if they are not fully informed—and if solutions are developed without their consultation—it may be the case that products, services and solutions are not relevant or appropriate. Technological advances may mean improved machines on large farms, for example, potentially increasing food production, but since the key points of food insecurity in the world are on small-scale farms managed by women throughout the Global South, such capital investments will have little impact in the areas where food production is most critical—and where women’s knowledgeable implementation of appropriate innovative technologies could make the most difference.

OWSD 6th GENERAL ASSEMBLY AND INTERNATIONAL CONFERENCE

The conference theme is 'Women, science and development', exploring three areas of relevance: the importance of basic sciences for development; the impact of applied sciences on development, and including sex and gender as variables in scientific research.

technical paper

The International Conference on Electron, Ion and Photon Beam Technology and Nanofabrication (EIPBN), affectionately known as "3-Beams," is the premier gathering of scientists and engineers who are dedicated to electron, ion and photon lithography, imaging, and analysis; atomically precise fabrication; nanofabrication process technologies and related emerging technologies; and their applications in a broad spectrum of fields. In its 64th meeting, researchers from academia, government laboratories, and industry from around the world meet to present and discuss recent and future trends in these technologies.

Current networks of neurons show a biology, which represents functions similar to those reported for fetal human brain. Human brain modelling on chip can shine light on in vivo-like message passing from neuron to neuron in a dish.

Moonshot: Nanofabricating neural networks

Here, we will show the application of Cryo-FIBID to other precursors beyond W(CO)6, with the aim of obtaining ultrafast growth of metallic deposits, and eventually additional functional properties. In particular, we will discuss the results obtained using the (CH3)3Pt(CpCH3) precursor, which is commonly found in commercial FIB equipment.

CMOS back-end-of-line integration is a very promising technology for the next generations of integrated circuits. Yet, electron beam lithography and alignment on multiple underlying metal layers and structures is challenging. In this paper, we present an image correlation strategy, procedure and markers to reach alignment accuracy better than 5 nm.

Comparison of alignment markers and method for electron-beam lithography on CMOS dies

Using high current focused Xe ion beam milling we fabricated ultra-deep and high quality micro-axicons in such a challenging material for microfabrication as lithium niobate. The axicons generate sub-wavelength focused beam over extended depths of focus with potential applications in microscopy and particle trapping.

Our goal in this paper is to demonstrate a process flow for the fabrication of silicon tips using KOH based wet etching and Cryo or Bosch based dry etching approaches.

Fabrication of Silicon Micro Tips for Microbial Cell Lysis Applications

We have developed a new technology for detecting single DNA molecules on-chip. A nanofluidic device was fabricated in a multi-step process to unfold the molecules in 3D inlets and guide them inside the nanochannels. No external field is applied, allowing high throughput and generate enormous data in real-time.

Blood separation and processing is a vital and essential step in numerous medical and clinical tests. We present here a unique deformable nanodevice functionalized by three-dimensional (3D) microbeads for plasma separation and blood cells retrieval.

Deformable Microbeads-stacked Nanodevice for Blood Plasma Separation and Blood Cells Retrieval

Label-free optical observation of transparent nano-objects is challenging. We present PlAsmonic NanO-apeRture lAbel-free iMAging (PANORAMA) to image, size, count and monitor single nanoparticle with a size limit approaching sub-10 nm. Molecular imaging is envisioned with functionalized substrates for single nanoparticle analysis for extracellular vesicles (e.g., exosomes) and pathogens (e.g., viruses).

A new label-free plasmonic imaging technique for quantitative analysis of transparent nanoscale objects approaching molecular size

We develop a broadband and omnidirectional tunable resonators with polarization-free high light absorption by preparing a hexagonally patterned array of free-standing SiO2_Ag core-shell nanoparticles. It is the result of hybrid optical modes consisting of Plasmon modes and whispering gallery modes.

Omnidirectional and band-tunable light absorption in free-standing dielectric-metal core-shell resonator arrays

We present optically resonant bipartite metal nano-cylinder arrays fabricated using electron beam lithography. The arrays utilise two different structure sizes with diameter differences as small as 10 nm. We show that this can be achieved and that the arrays show a resonance response that agrees with electromagnetic simulations.
