Actually if you look at it from a scientific view, yes.
To tansmute matter theretically it would take a relatively small amount of energy since all you're doing is breaking the molecular bonds between the atoms. depending on the strength of the bonds it shouldn't be too hard. you fuse carbon and oxygen everyday just through respiration.
Spontaneously creating matter however is still possible but it takes a phenominal amount of energy. to work out exactly how much you would have to use e=mc2. This is how the material universe was made, the big bang was purely energy and a lot of that energy became matter. So yes it's possible but you would need more energy than the sun.
Long story short, yes you can transmute and create matter and i'm sorry if i got to technical and bored you.

It would take a high degree of coordination and coherence and not a high amount of energy since when a person uses psychokinesis, they are not generating any energy at all. The history of the state involved is manipulated via coordination of initial states, so energy states leading up to where energy could have gone to create that state is shifted around leading to that particular action. The motion of the particles involved in the said state can be modeled by stochastic differential equations, such as Brownian Motion, in which the collective shift in the macrophysical system can happen as a result of a high coherent organization among the individual collisions of the smaller particles involved. In a heated gas, for example, each heated particle has kinetic energy in a random direction which will randomly bounce off of others not particularly creating any type of pattern as it expands outward. Now, if a person is able to say force the gas to stay in a spherical shape or form it into any other coherent form, they are creating a particular order in the random direction of the kinetic energy involved in how the collisions happen among the particles within which happens as a result of coordination of the trajectory of energy involved which ties into future extrapolations and initial states. This is what happens when a person creates a force bubble or a force ball. They are manipulating the trajectory of kinetic energy in a coherent fashion due to the organization of a particular trajectory.
Using energy alone, no. But using kinesis, its possible with high improbability. Even so, kinesis on a microscopic scale at all is no small matter anyway, but even if you can there's little point to doing the things your suggesting. There are far more productive uses for kinesis on any scale, and certainly far easier things it can be used to do.
The position and momentum of an electron is more a finite approximation over an exact visible boundary due to the uncertainty involved versus larger physical objects which are more deterministic, thus, it would actually be easier to manipulate the trajectory of an electron to shift around molecules, to bond molecules together, break molecular bonds, and set off chemical reactions.
As far as experimental evidence goes, you have more successful experiments dealing with the the manipulation of electrons, photons, and self-assembling molecules than with such things as moving a chair across the room.
All that being said, it would be possible to materialize, teleport, or phase an object via projection of a strongly organized and coherent template of information by manipulating the initial states of that history creating a future extrapolation which contains that particular change. The paths something can take to get to a place are infinite without the influence of entropy or decoherence, so selection of a particular trajectory in such a way that it is the only one that could happen can help. The issue with transmuting things has to do with with over coming the
strong and
weak forces involved, so you have the nuclear physics to contend with.
To clarify, how this happens clashes with the quantum arrow of time, the classical arrow of time, decoherence, and entanglement.
In my experience, it is unlikely that people are able to create this type of coherent organization on their own, so teleportation, phasing, and materialization usually require more than one person.
There is also the issue of whether or not how an intention is represented is veridical(a genuinely real thing instead of just a perceived thing). An intention is an extension of intentionality in which intentionality is how we think about or of an object in which our mind points to the represented thing, but this representation can be about something that need not exist, thus, a person can have a a non veridical intention in which the intention is not the accurate representation of the intended state. This can be somewhat solved by tacking on explicit linguistic representations, such as ideograms, to tested representations of this intended thing with appropriate feedback.
I am currently tinkering with a liquid crystal that I made out of an ester of cholesteryl benzoate. When I interact with it in its chiral phase, its pitch changes thereby making its color change. It is a fun way to do psychokinesis on helix molecules. It is fun having a crystal that you use in your practices that actually responds to you and way more interesting than a psi wheel. Instructions on how to make a cholesteric liquid crystal with a break down of information on it can be found here:
Preparation of Cholesteryl Ester Liquid Crystalsfor ex. Split an oxygen atom and fuse protons, neutrons and electrons into hydrogen atoms.

It is possible to shift electrons about in their orbitals within an electron cloud to play around with molecular configurations, but nuclear transmutations would require over coming the strong force which has not been seen in experimental evidence dealing with psychokinesis.
