This report takes a look into the patenting activity around gallium Nitride uncovering the companies, inventors, and key applications.
GaN is a binary III-V direct bandgap semiconductor commonly used in LEDs. Its wide-band gap of 3.4 eV affords its special properties for applications in optoelectronic, high-power and high-frequency devices. Because GaN offers very high breakdown voltages, high electron mobility, and saturation velocity it is also an ideal candidate for high-power and high-temperature microwave applications like RF power amplifiers at microwave frequencies and high-voltage switching devices for power grids. Solutions that use GaN-based RF transistors are also replacing the magnetrons used in microwave ovens.
Gallium Nitride (GaN) transistor models have evolved from GaAs (gallium arsenide) transistor models; however there are many advantages GaN offers:
• Higher operating voltage (over 100-V breakdown)
• Higher operating temperature (over 150°C channel temperature)
• Higher power density (5 to 30 W/mm)
• Durable and crack-resistant material
GaN devices are often grown on SiC (silicon carbide) substrates, but to achieve lower-cost GaN devices, they can be grown on sapphire and silicon wafers. GaN’s wide bandgap allows for higher breakdown voltages and operation at high temperatures. The high thermal conductivity of SiC makes it a better substrate than silicon for power amplifier applications that require good heat sinking.

Nanotechnology is the purposeful manipulation of matter on an atomic scale. Materials created in this manner often exhibit unique physical and chemical properties, which have useful applications in various industries. A growing use for some types of engineered nanomaterials is in the area of environmental remediation, termed nanoremediation. While this technique appears to be effective for cleanup, there are still many unanswered questions regarding its long-term impact to environmental quality and human health. No long-term studies exist regarding the potential environmental impact of nanoremediation. While animal studies have shown the potential for adverse health effects, limited data regarding human health are available. The US Environmental Protection Agency is currently adapting existing regulations to cover the use of nanomaterials in remediation, but this approach is limited. Many questions still remain regarding fate and transport, verification of clean-up, and potential occupational and community exposures.

This document describes a study that deposited titanium dioxide (TiO2) onto cheesecloth via physical vapor deposition to create a photocatalytic material for wastewater treatment. The methodology involved preparing cheesecloth and depositing TiO2 using a compact plane magnetron setup. Characterization of the untreated and treated cheesecloth found that the TiO2 coating made the cloth harder, more hydrophilic, and brighter in color. Analysis using XRD, FTIR, SEM, EDX, and TGA confirmed the successful deposition of anatase TiO2 nanoparticles onto the cheesecloth. The conclusion is that TiO2-coated cheesecloth could be a low-cost and environmentally friendly photocatalytic support material for wastewater treatment

Dipartimento di Informatica, Sistemistica e Comunicazione,
Università di Milano Bicocca
Internet e telemedicina sostenibile per i
Paesi in via di sviluppo: una introduzione
1
2. Il messaggio di questo intervento
Di telemedicina si parla fin dagli anni '70 del secolo
scorso, ma è con i recenti sviluppi di Internet che è
possibile realizzare applicazioni di telemedicina a
basso costo per i Paesi in via di sviluppo:
"Affordable telemedicine"
2
3. Che cos'è la telemedicina
"Telemedicine is the delivery of health care services,
where distance is a critical factor, by all health care
professionals using information and communication
technologies for the exchange of valid information for
diagnosis, treatment and prevention of disease and
injuries, research and evaluation, and for the continuing
education of health care providers, all in the interest of
advancing the health of individuals and their
communities.”
WHO, Telemedicine, Opportunities and Developments in Member States, 2010

5. Ostacoli all'adozione della telemedicina
secondo OMS
Nei Paesi sviluppati:
Problematiche legate alla protezione e riservatezza delle
informazioni legate alla salute dei pazienti
Altre priorità
"Perceived lack of demand"
Nei Paesi in via di sviluppo:
Disponibilità e manutenzione delle infrastrutture necessarie:
instabilità della rete elettrica, disponibilità e affidabilità della
connettività Internet, larghezza di banda, computer virus,
disponibilità di personale tecnico competente

6. Ma possiamo essere "molto"
ottimisti…
La connettività internet è in costante miglioramento, anche
nei Paesi in via di sviluppo
L'evoluzione delle tecnologie software abbassa
continuamente i costi dello sviluppo delle applicazioni
(piattaforme open-source, "ecosistemi" di componenti
compatibili)
Lo sviluppo del cloud computing, e in particolare del
"software as a service" elimina gli investimenti iniziali in
infrastrutture di calcolo (capex → opex)
La rapidissima crescita della telefonia mobile in tutto il
pianeta
La convergenza telefonia mobile / internet

LDC defined by UN, based on 3 criteria:
Low income
Human resources weakness
Economic vulnerability
In LDCs two thirds of people
have cellular coverage and
mobile cellular penetration
has reached 34% - up from
5% five years earlier

Video-telefonia IP, gratuita
Dal 2003, poi acquisita da eBay nel 2005, quindi da
Microsoft nel 2011
700 milioni di accounts; un terzo di tutte le
telefonate internazionali passano per Skype

27. Più in generale: e-health
Electronic health records: enabling the communication of patient data between
different healthcare professionals
Telemedicine: physical and psychological treatments at a distance
Consumer health information: use of online resources on medical topics by healthy
individuals or patients
Health knowledge management: best practice guidelines, online resources for the
healthcare professionals, epidemiological tracking
Virtual healthcare teams: healthcare professionals collaborating and sharing
information on patients through online communication tools
M-health: using mobile devices in collecting patient health data, providing healthcare
information, real-time monitoring of patient vitals, and direct provision of care
Healthcare online information systems: for hospital and healthcare professionals:
appointment scheduling, patient data management, work schedule management and other
administrative tasks surrounding health

31. Conclusioni
Con l'evoluzione di Internet degli ultimi anni, e con
la convergenza fra internet e telefonia mobile, si
aprono possibilità impensabili fino a pochi anni fa
Le tecnologie abilitanti: comunicazioni a basso
costo in tempo reale o differito; cloud computing,
software open-source, telefonini a basso costo,
banda larga
