Alfa Chemistry Launches Graphene Quantum Dot Modification Services

Oct 20, 2022 | Business


GQD stands out among materials even without modification due to its low cost, stable fluorescence, low toxicity, and good biocompatibility compared to the traditional semiconductor quantum dot. Interestingly, upon modification utilizing a wide range of techniques, such as doping with heteroatoms, conjugation with conducting polymers, or incorporating various nanoparticles, GQDs exhibit enhanced properties and demonstrate better performance in many application scenarios.



“With an extensive choice of design strategies, scientists are now trying to investigate and crystallize the underlying mechanisms as well as potentials behind each type of modified graphene quantum dots,” said the Marketing Chief of Alfa Chemistry. “So far, modified graphene quantum dots, with combined merits of graphene and quantum dots, have been broadly used in applications, e.g., biological imaging, fluorescence sensing, photocatalysis, supercapacitor, solar photovoltaic devices, adsorption, and separation.”



Future research on graphene quantum dots can be initiated from aspects of preparation strategies, mechanism exploration, performance regulation, and application effects.



Currently, Alfa Chemistry provides the following modification options for clients across the globe:



Amidation


Amide bond


Chloride Formation


Imine Formation


Epoxide Ring Opening


Electrophilic Aromatic Substitution



“Our multidisciplinary experts are well-positioned to answer any modification-related questions and formulate the most suitable strategies for GQD modifications. Meanwhile, simulations are often used to design functional target groups, establish structural feature models, and guide new product synthesis,” the Chief further added.

Statement by ExCo Non-official Members on important instruction of President Xi Jinping

***************************************************************************************


The following is issued on behalf of the Executive Council Secretariat:

      

     The Non-official Members of the Executive Council (ExCo Non-official Members) today (February 16) issued the following statement:

      

     The ExCo Non-official Members expressed their heartfelt gratitude to President Xi Jinping’s deep concern and important instruction on fighting the fifth wave of the COVID-19 epidemic in Hong Kong. The Members strongly support the Hong Kong Special Administrative Region (HKSAR) Government to assume the main responsibility to stabilise the epidemic situation soonest possible by implementing various anti-epidemic measures and according that the utmost priority.

      

     The ExCo Non-official Members said that, in the face of the fifth wave of the epidemic, the HKSAR Government has spared no effort in taking forward various anti-epidemic measures. However, the pace with which the disease has been spreading has outraced Hong Kong’s handling capacity. The Central Authorities’ ardent concern for Hong Kong and strong support at this critical juncture has encouraged and touched the hearts of the people of Hong Kong and reinforced our confidence in fighting the epidemic. It fully demonstrates that the Central Authorities have all along been providing their strongest support for the HKSAR under “One Country, Two Systems”.

      

     The ExCo Non-official Members would continue to take an active role in advising Hong Kong’s anti-epidemic work and render their full support to the HKSAR Government to, in accordance with the important instruction of President Xi Jinping, mobilise all available manpower and resources and adopt all necessary measures to safeguard the lives and health of the Hong Kong people and the stability of our society.

      

     The ExCo Non-official Members appeal to the public to fight the epidemic hand in hand with the Government by complying with the anti-epidemic requirements and heeding to the Government’s call to get vaccinated as soon as possible. The Members believe that, with the staunch support from the Central Authorities and the concerted efforts of the community, Hong Kong will overcome the difficulties and prevail over the epidemic.
